Chapter 1: The Decision to Incorporate — Owner-Manager Compensation Planning

Section 1.1: Why Incorporate?

A private corporation occupies a central position in Canadian tax planning for business owners. Incorporation creates a separate legal entity distinct from its shareholders, enabling business income to be taxed at the corporate rate rather than flowing directly to the individual at marginal personal rates. In Canada, the small business deduction (SBD) under ITA section 125 reduces the federal corporate tax rate for Canadian-controlled private corporations (CCPCs) earning active business income (ABI) below $500,000 per year to roughly 9% federally, dramatically lower than the top personal marginal rates of 45–54% depending on province.

Canadian-Controlled Private Corporation (CCPC): A private corporation incorporated in Canada that is not controlled, directly or indirectly, by non-residents or public corporations (ITA s. 125(7)). CCPCs enjoy preferential tax treatment including the small business deduction, the refundable dividend tax on hand (RDTOH) regime, and shareholder eligibility for the lifetime capital gains exemption on qualifying shares.

The deferral advantage is the primary driver of incorporation for high-income owner-managers. When business profits remain inside the corporation, the tax owing on retained earnings is at the low corporate rate. The owner-manager pays personal tax only when funds are extracted — through salary, dividends, or other means — creating a pool of after-tax corporate funds that can be invested and compounded before the personal tax is triggered. The deferral amount is roughly the difference between the top personal marginal rate and the corporate SBD rate, which in Ontario is approximately \(53.53\% - 12.2\% = 41.33\%\) on every dollar retained. This is a profound long-term advantage when compounded over decades.

The integration system in Canada aims to eliminate the double taxation inherent in corporate structure. True integration means a business owner should pay the same total tax whether income flows through a corporation or is earned personally. Canada achieves approximate integration through the dividend tax credit (DTC) system: when a CCPC pays an eligible or non-eligible dividend, the shareholder grosses up the dividend and receives a credit intended to represent the corporate tax already paid. Perfect integration rarely exists because provincial rate variations and the SBD create gaps.

Integration Gap: In Ontario, integration for active business income taxed at the CCPC SBD rate is slightly negative — meaning there is a small tax cost (rather than savings) to earning income through a corporation and paying it out as a non-eligible dividend compared to earning it personally. This is because the non-eligible dividend gross-up and DTC were calibrated for the general corporate rate, not the lower SBD rate. Practitioners must run province-specific integration calculations to quantify the actual gap.

Section 1.2: Salary vs. Dividends — The Compensation Mix Decision

The owner-manager who controls a CCPC must decide how to extract value from the corporation. The two primary channels are salary (and bonuses) and dividends. Each carries distinct tax implications.

Salary is deductible to the corporation under ITA s. 9, reducing its taxable income dollar-for-dollar. Salary creates earned income for RRSP contribution room (18% of prior year earned income, subject to the annual dollar limit — $32,490 for 2025), CPP contributions (both employee and employer portions), and may be required to substantiate the corporation’s claim for the SBD if the owner provides management services. However, the employer (corporation) must remit payroll source deductions monthly and contribute to CPP and EI on the owner-manager’s behalf, adding administrative burden.

Dividends are paid from after-tax corporate profits and are not deductible at the corporate level. They are taxed at the personal level but at reduced effective rates due to the dividend gross-up and tax credit mechanism. Non-eligible dividends (from a CCPC paying SBD-rate tax) carry a 15% gross-up and a federal DTC of roughly 9.03%, while eligible dividends (from income taxed at the general corporate rate) carry a 38% gross-up and a 15.02% federal DTC.

Example — Salary vs. Dividend in Ontario (2025): A CCPC earns \$200,000 of active business income qualifying for the SBD. Scenario A: the corporation pays \$100,000 salary to the owner-manager in the top bracket (53.53% combined federal-provincial). Scenario B: the corporation retains the same amount after SBD rate (12.2% = 9% federal + 3.2% Ontario), leaving approximately \$87,800 after corporate tax, and pays a non-eligible dividend.

Under Scenario A: salary reduces corporate income by $100,000. The owner-manager pays $53,530 in personal tax, netting $46,470.

Under Scenario B: corporate tax on $100,000 = $12,200, leaving $87,800. Non-eligible dividend gross-up: \( \$87,800 \times 1.15 = \$100,970 \). Personal tax at top rate less DTC ≈ 44.7% effective on grossed-up amount. Net after personal tax ≈ $47,600.

The dividend route provides a small net benefit here, but the salary route generates RRSP room and CPP benefits that may justify the difference.

The optimal salary-dividend mix depends on the owner’s personal tax bracket, RRSP room needs, provincial tax rates, and whether CPP coverage is desired. Many practitioners recommend paying enough salary to maximize RRSP room (\( \text{RRSP room} = 18\% \times \text{prior year earned income} \)) and then extracting additional amounts as dividends.

Bonuses are a special case. A year-end bonus declared but not yet paid is deductible by the corporation in the fiscal year declared, provided it is paid within 180 days after the corporation’s fiscal year end (ITA s. 78(4)). This allows income-shifting: a corporation with a non-calendar fiscal year can declare a bonus at fiscal year-end and pay it in the owner’s next personal tax year, creating a further deferral.

Section 1.3: Tax on Split Income (TOSI)

The Tax on Split Income rules, substantially expanded in 2018, are designed to prevent income-splitting with family members who do not genuinely contribute to a business. Before TOSI, owners commonly paid dividends to adult children or spouses holding shares in the family company, diverting income taxed at lower personal rates.

Tax on Split Income (TOSI): A set of rules under ITA section 120.4 that applies the highest personal marginal rate to certain types of income received by a specified individual from a related business. TOSI applies when the recipient has not made an adequate labour or capital contribution to the business. TOSI overrides the normal rate structure and cannot be offset by personal tax credits (other than the basic personal amount and dividend tax credit).

TOSI applies to split income which includes dividends and shareholder benefits received by a specified individual (generally a person related to a business owner who is resident in Canada) from a related business unless an exclusion applies. Key exclusions include:

  • Reasonable return exclusion: The income does not exceed a reasonable return given the recipient’s labour contribution, property contribution, and risk assumed. The “reasonable return” test is inherently fact-specific and may require professional judgment.
  • Excluded business rule: A specified individual who is aged 18 or older and who has made a regular, continuous, and substantial labour contribution (generally at least 20 hours per week on average in the current taxation year, or in any five prior taxation years) is excluded from TOSI for dividends.
  • Excluded shares rule: Available to individuals 25 or older if they hold shares representing at least 10% of votes and value of the corporation, the corporation earns less than 90% of its income from services, and it is not a professional corporation.
  • Safe harbour for adults 25+: Dividends received by a specified individual aged 25 or older are excluded if they relate to a business in which a source individual is actively engaged (excluding “safe harbours” that have been revoked).

The effect of TOSI is to tax the split income at the top personal marginal rate applicable to the individual, regardless of their actual bracket. Planning around TOSI requires careful documentation of family members’ contributions to the business.


Chapter 2: Shareholder Benefits and Loans

Section 2.1: Shareholder Benefits

When a corporation confers a benefit on a shareholder or a person connected to the shareholder, section 15(1) of the ITA includes the value of that benefit in the shareholder’s income. This prevents disguised distributions that avoid the dividend gross-up and tax credit mechanism.

Shareholder Benefit (ITA s. 15(1)): Any benefit or advantage conferred on a shareholder by a corporation, the value of which is included in the shareholder's income. Common examples include personal use of corporate assets (automobiles, vacation properties), payment of personal expenses by the corporation, and below-market loans. The benefit is valued at fair market value (FMV).

The valuation of benefits follows FMV principles. If the corporation owns a vacation property and the owner-manager uses it for personal weeks, the benefit is the FMV of the rental value for those weeks. Where a benefit is included under s. 15(1), it is not deductible by the corporation (preventing a second tax saving), and does not generate dividend gross-up or DTC entitlement — making shareholder benefits generally the least efficient method of owner-manager compensation.

Connected shareholder: The benefit rules extend to persons “connected” with a shareholder (defined in s. 186(4)), meaning benefits conferred on family members can also be caught.

Double Inclusion Risk: Where both s. 15(1) and s. 6(1) (employment benefits) could apply, the courts have generally held that s. 6(1) takes priority where the individual is also an employee. However, where the individual receives the benefit solely in their capacity as shareholder (not as an employee), s. 15(1) applies. The distinction matters because employment benefits attract CPP and EI withholdings while s. 15(1) amounts do not.

Section 2.2: Shareholder Loans

Section 15(2) of the ITA requires a shareholder who is also an employee (or related person) to include amounts owing from the corporation in income unless the loan:

  1. is repaid within one year after the end of the corporation’s taxation year in which the loan was made, and
  2. is not part of a series of loans and repayments.

If the loan is not repaid in time, the full amount is included in the shareholder’s income in the year the loan was made. When it is eventually repaid, a deduction under s. 20(1)(j) is available to prevent double-taxation.

Prescribed rate loans: Even if a shareholder loan avoids s. 15(2) inclusion, s. 80.4 may still apply an interest benefit if the loan bears interest below the CRA-prescribed rate. The deemed interest benefit is the difference between the prescribed rate and the actual rate charged, included in the shareholder’s income. The prescribed rate for Q4 2025 is set quarterly based on the 90-day T-bill rate plus 2 percentage points.

Bona fide exceptions (ITA s. 15(2.2)): Certain loans are excluded from s. 15(2) if they are made in the ordinary course of the corporation’s business (e.g., a financial institution lending to an employee-shareholder on the same terms as to other customers), or if the loan is made to enable the employee-shareholder to purchase a home, buy shares of the corporation (or a related corporation) under a stock option plan, or purchase an automobile for employment use — provided a bona fide arrangement for repayment exists at the time the loan is made.


Chapter 3: Employment Benefits and GST/HST Considerations

Section 3.1: Employment Benefits

Owner-managers who are also employees of their corporation may receive employment benefits subject to the employment income rules under section 6 of the ITA rather than the shareholder benefit rules. Where a benefit can be characterized as employment income, it is still taxable but may carry more favourable treatment in some circumstances.

Key employment benefits include:

  • Company vehicle: The standby charge for the personal use of a company automobile is calculated as 2% per month of the original cost (or lease payments) for each month the car is available (ITA s. 6(1)(e)). An operating expense benefit of $0.33 per kilometre (2025 rate) for personal use may apply in addition.
  • Life insurance premiums: Group term life insurance premiums paid by the employer beyond $25,000 of coverage are a taxable benefit under s. 6(1)(a).
  • Low-interest loans: Employment-related loans at below-prescribed rates trigger a taxable benefit equal to the difference between prescribed and actual rates (ITA s. 80.4(1)).

Section 3.2: GST/HST and the Owner-Manager

The Goods and Services Tax / Harmonized Sales Tax (GST/HST) regime under the Excise Tax Act (ETA) intersects with corporate and personal tax planning in several important ways.

GST/HST: A federal value-added tax (5% GST or combined with provincial component as HST at 13% in Ontario, 15% in Atlantic provinces, 12% in B.C.) that applies to most supplies of goods and services in Canada. Registrants collect GST/HST on taxable supplies and claim input tax credits (ITCs) on business inputs.

Registration thresholds: A corporation (or individual) must register for GST/HST once its taxable supplies exceed $30,000 in a calendar quarter or in four consecutive quarters. Owner-managed corporations almost always exceed this threshold quickly.

Salary vs. dividends — GST/HST angle: Salary paid to an owner-manager is not a taxable supply and carries no GST/HST implications. Dividends are also not subject to GST/HST. However, where an owner-manager provides management services personally (as opposed to through the corporation) to a third party, that supply may be subject to GST/HST.

Employee vs. independent contractor: When an individual provides services as an employee, no GST/HST is charged. When they provide services as an independent contractor or through a corporation, GST/HST applies. The ITA and ETA tests for employment vs. self-employment differ somewhat; advisors must apply both.

Quick Method Election: Small registrants with taxable supplies under $400,000 per year may elect the Quick Method, remitting a flat percentage of HST collected rather than computing actual ITCs. This can simplify compliance and sometimes create a financial benefit.


Chapter 4: Share and Asset Sales — Structuring Corporate Dispositions

Section 4.1: Capital Dividends and the Capital Dividend Account

The capital dividend account (CDA) is a notional account maintained by a private corporation that tracks certain tax-free surpluses that can be paid out as tax-free capital dividends to Canadian-resident shareholders.

Capital Dividend Account (CDA): A notional account for private corporations under ITA section 89(1) that accumulates the non-taxable portion of capital gains, life insurance proceeds (net of adjusted cost basis of the policy), and other tax-free items. Amounts in the CDA can be distributed to shareholders as tax-free capital dividends elected under ITA s. 83(2).

When a corporation realizes a capital gain, only the taxable capital gain (the included fraction — 2/3 for 2025 for gains above $250,000 threshold, or 1/2 for gains up to that threshold after the June 2024 Budget changes) is included in taxable income. The excluded portion (the non-taxable portion) is added to the CDA. A corporation elects under s. 83(2) to pay a capital dividend equal to the CDA balance; the shareholder receives the dividend completely tax-free.

CDA Planning Note: The 2024 Federal Budget proposed increasing the capital gains inclusion rate from 1/2 to 2/3 for gains realized on or after June 25, 2024, for corporations and trusts (with a \$250,000 annual threshold for individuals). As of Fall 2025, this increase was legislated but remains politically contentious following the change in government. Advisors should confirm the current status. For gains below the individual annual threshold, the 1/2 inclusion still applies.

Section 4.2: Paid-Up Capital

Paid-up capital (PUC) represents the legal stated capital of shares as modified for tax purposes under the ITA. PUC is the amount that can be returned to shareholders without triggering a deemed dividend. When PUC is reduced — for example, when shares are redeemed or repurchased — any excess of the redemption price over PUC is deemed a dividend under section 84.

PUC reduction planning: Advisors use PUC to structure tax-efficient returns of capital to shareholders. Where a corporation has built up PUC (e.g., through share subscriptions at high prices), shareholders can receive funds in excess of their ACB without dividend treatment — though they still face a capital gain on any excess over their ACB.

PUC Grinding (ITA s. 84.1): Where an individual transfers shares of a private corporation to another private corporation with which they do not deal at arm’s length, s. 84.1 grinds (reduces) the PUC of the shares issued by the acquiring corporation. The grind prevents individuals from converting what would otherwise be a dividend into a return of PUC followed by a capital gain eligible for the LCGE. This is a specific anti-avoidance rule targeting surplus stripping.

Section 4.3: Share Redemptions

When a corporation redeems its shares (buys them back from the shareholder), two potential tax events occur simultaneously for the shareholder:

  1. Deemed dividend = Redemption proceeds − PUC of the shares redeemed (ITA s. 84(3))
  2. Capital gain or loss = ACB − (Redemption proceeds − deemed dividend)

This interaction prevents the shareholder from receiving double tax-free treatment: the PUC gives rise to a reduced deemed dividend, while the capital gain is calculated on the after-dividend amount.

Example — Share Redemption: An owner-manager holds common shares with ACB = \$50,000 and PUC = \$1,000. The corporation redeems the shares for \$500,000.

Deemed dividend = $500,000 − $1,000 = $499,000. This is treated as a taxable dividend (non-eligible if the corporation is a CCPC paying from income taxed at SBD rates).

Adjusted proceeds for capital gain = $500,000 − $499,000 = $1,000.

Capital gain (loss) = $1,000 (adjusted proceeds) − $50,000 (ACB) = ($49,000 capital loss).

The capital loss can be applied against capital gains, but the deemed dividend cannot offset it. This illustrates why the mechanics of s. 84(3) are critical — the loss arises because the deemed dividend absorbs most of the proceeds.

Section 4.4: Share Sale — Capital Gains Exemption and QSBC Shares

The lifetime capital gains exemption (LCGE) shields qualifying capital gains from tax. For qualifying small business corporation (QSBC) shares, the exemption for the 2025 tax year is approximately $1,016,602 (indexed annually to inflation). For farming and fishing property, the exemption is $1,250,000.

Qualifying Small Business Corporation (QSBC) Share (ITA s. 110.6(1)): A share of a small business corporation (SBC) meeting these conditions: (1) throughout the 24 months immediately preceding disposition, the share was not owned by anyone other than the taxpayer or a related person; (2) throughout that period, more than 50% of the FMV of the SBC's assets were used principally in an active business carried on primarily in Canada; and (3) at the time of disposition, the corporation is an SBC (a CCPC whose assets are at least 90% qualifying active business assets).

Crystallizing the LCGE: Owner-managers sometimes “crystallize” the exemption before the corporation grows beyond the $10M asset cap for SBC status or before the LCGE is used up by other gains, using a section 85 rollover or other reorganization to trigger a capital gain while the exemption is still available. Crystallization also “bumps” the ACB of shares, reducing future taxable gains.

Multiplication of the LCGE: Where shares are held by a family trust, multiple beneficiaries (each with their own LCGE) can potentially claim the exemption on the same underlying corporate gain when shares are sold, multiplying the exemption across the family. This strategy is subject to TOSI and requires careful trust drafting.

Section 4.5: Asset Sales and Wind-Up

When a business is sold through an asset sale, the vendor corporation sells individual assets (inventory, equipment, goodwill, real estate). Each asset class produces different tax consequences:

  • Inventory: Proceeds less cost of inventory = business income, fully taxable.
  • Depreciable property: Proceeds less UCC = recaptured CCA (business income, ITA s. 13(1)) or terminal loss (ITA s. 20(16)); proceeds greater than original cost = capital gain.
  • Class 14.1 property (goodwill, post-2016): Eligible capital property was converted to Class 14.1 depreciable property in 2017. The rate is 5% declining balance. Recapture and capital gains apply as with other depreciable property.
  • Land: Capital gain on the appreciation above ACB.

An asset sale is generally preferred by the buyer (because they get a stepped-up cost base for CCA) but less preferred by the seller (because proceeds are trapped in the corporation, requiring a second level of tax to extract).

A subsequent wind-up (dissolution) of the corporation triggers further tax events. The corporation is deemed to dispose of assets at FMV. Proceeds go to shareholders who face a deemed dividend equal to the wind-up proceeds less PUC, followed by a capital gain (or loss) on the shares.


Chapter 5: Corporate Reorganizations — Advanced Rollover Provisions

Section 5.1: Section 85 — Transfer of Property to a Corporation

Section 85 of the ITA allows a transferor (an individual, corporation, or trust) to defer tax on a disposition of eligible property to a taxable Canadian corporation in exchange for shares of that corporation, provided both parties file a joint election (T2057). The transfer price (the elected amount) can be set anywhere between the property’s ACB (or UCC for depreciable property) and FMV, allowing the transferor to elect an amount that avoids recognizing a gain while giving the corporation a cost base equal to the elected amount.

Eligible Property for s. 85 Transfer: Property that qualifies for a s. 85 rollover includes capital property (both depreciable and non-depreciable), eligible capital property (now Class 14.1), resource property, and inventory other than real property inventory. Notably, real property inventory does not qualify, nor do personal-use property items.

Elected amount constraints: The elected amount must satisfy the following conditions simultaneously:

  • Not less than the FMV of any non-share consideration (boot) received
  • Not more than the FMV of the transferred property
  • For non-depreciable capital property: not less than the lesser of FMV and ACB (to prevent artificial losses)
  • For depreciable property: not less than the lesser of FMV, UCC, and original cost
Example — Section 85 Rollover with Depreciable Property: An owner-manager transfers a piece of equipment to a new corporation. The equipment has original cost \$100,000, UCC \$60,000, and FMV \$80,000. Boot received: a promissory note for \$20,000. Shares received at FMV of \$60,000.

Elected amount must be at least $20,000 (boot) and at most $80,000 (FMV). To avoid recapture, elect $60,000 (= UCC).

Tax consequence to transferor: proceeds = $60,000 = UCC, so no recapture and no terminal loss. No capital gain since proceeds ($60,000) = ACB for capital gain purposes = UCC. Corporation’s cost of equipment = $60,000. When the corporation later sells the equipment for $80,000, it recognizes $20,000 of recapture (proceeds $80,000 − UCC $60,000) — the gain deferred at the time of rollover flows through at the corporate level.

GST/HST on section 85 transfers: GST/HST may apply to the transfer of eligible capital property. The joint election under ETA section 167 (the “going concern” election) can eliminate GST/HST on the transfer of a business as a going concern, but care must be taken to ensure the conditions are satisfied.

PUC and ACB of shares received: The PUC of shares received in a s. 85 rollover is the lesser of the elected amount less boot and the legal PUC of those shares. This ensures that the shareholder cannot create artificial high PUC (which could later be returned tax-free) through the rollover.

Section 5.2: Section 86 — Share-for-Share Exchange / Reorganization of Capital

Section 86 allows a shareholder to exchange old shares of a corporation for new shares of the same corporation as part of a reorganization of capital without immediate recognition of a capital gain. Common uses include:

  • Creating preferred shares redeemable at a stated amount (a value freeze) — see Section 5.3
  • Restructuring share classes in anticipation of admitting new shareholders
  • Separating PUC for estate planning purposes

The shareholder’s ACB of the new shares received is determined by the PUC of the old shares surrendered plus any gain triggered (from non-share consideration received in excess of PUC). The FMV of non-share consideration cannot exceed the FMV of the shares surrendered; exceeding this amount creates a deemed dividend under s. 84(3).

Section 86 vs. Section 85: Unlike s. 85, s. 86 does not require a joint election — it applies automatically when the specified conditions are met. However, s. 86 only applies to same-corporation share exchanges. Cross-corporation transfers of shares require s. 85 or s. 85.1 (share-for-share exchanges between corporations).

Section 5.3: The Estate Freeze

An estate freeze is a corporate reorganization technique that fixes (“freezes”) the current owner-manager’s equity at today’s value and shifts all future growth in corporate value to the next generation. This limits the owner-manager’s eventual capital gain on death and shifts wealth to heirs who can potentially access their own LCGEs.

Classic s. 86 freeze mechanics: The owner-manager holds, say, 1,000 common shares with FMV of $2,000,000 and ACB of $100,000. The corporation reorganizes its capital: the owner-manager surrenders the common shares and receives:

  • 2,000 preferred shares with a redemption value of $1,000 each (total FMV = $2,000,000), fixed-rate non-cumulative dividend entitlement, and no participation beyond the redemption amount.
  • New common shares are simultaneously issued to children or a family trust at a nominal price (e.g., $1 per share), since they represent only the future growth potential with a current FMV of essentially nil.

After the freeze, when the corporation grows in value (say to $4,000,000), the preferred shares remain worth $2,000,000 and the new common shares are worth $2,000,000. The owner-manager’s estate exposure is capped; the $2,000,000 of growth belongs to the heirs.

Anti-avoidance risk: Freezes that are implemented at excessive valuations, or where the preferred shares are set with unreasonably high dividend rates, risk challenge under GAAR (s. 245) or the specific surplus-stripping rules (s. 84.1). Independent valuation of the corporation at the freeze date is essential.

Section 5.4: Section 87 — Amalgamation

When two or more taxable Canadian corporations amalgamate into a new (or continuing) corporation, section 87 provides a rollover that generally allows the transaction to occur without immediate tax consequences to the predecessor corporations or their shareholders.

Amalgamation (ITA s. 87): A statutory merger of two or more taxable Canadian corporations into a single continuing corporation. For tax purposes, the new corporation is deemed to be the same corporation as the predecessors with the same tax attributes (losses, UCC balances, CDA, etc.), subject to restrictions on the use of predecessor losses.

Key effects of s. 87:

  • Predecessor corporations are deemed to have disposed of their assets immediately before amalgamation at their tax cost (no gain or loss recognized at the corporate level)
  • The new corporation inherits tax attributes: UCC balances, CDA, RDTOH, GRIP, and loss carryforwards — subject to the loss utilization restrictions in s. 111(5)
  • Shareholders of the predecessor corporations receive shares of the new corporation; no gain is recognized on the exchange provided they receive only shares (no boot)
  • The ACB of shares received = ACB of shares surrendered

Loss restriction rules: Under s. 111(5), where an amalgamation results in an acquisition of control of a predecessor corporation, that corporation’s loss carryforwards may be restricted. Net capital losses are extinguished; non-capital losses are preserved but may only be deducted against income from the same or similar business.

Section 5.5: Section 88 — Winding Up a Subsidiary

Where a Canadian parent corporation owns at least 90% of the shares of a taxable Canadian subsidiary, the subsidiary can be wound up into the parent on a tax-deferred basis under s. 88(1). This is the corporate-to-corporate equivalent of death and probate.

The “bump” provision (s. 88(1)(d)): On a s. 88(1) wind-up, the parent corporation can elect to bump (increase) the cost base of certain non-depreciable capital property held by the subsidiary at the time of acquisition of control, up to the FMV of that property at the time the parent last acquired control of the subsidiary. This is a powerful planning tool: after an arm’s-length share purchase, the buyer can wind up the acquired company and bump the ACB of its underlying real estate or other capital property, reducing future taxable gains.

Bump Restrictions: The bump is not available for depreciable property, eligible capital property (now Class 14.1), or property that was substituted for excluded property. Planning to maximize the bump requires careful identification and preservation of qualifying property between the acquisition date and the wind-up.

Section 5.6: Butterfly Transactions (ITA s. 55)

A butterfly transaction is a complex corporate reorganization used to divide corporate assets among multiple shareholders (typically on the breakdown of a shareholder relationship or a family split) on a tax-deferred basis. The transaction routes assets through inter-corporate dividends protected from the application of s. 55(2).

Section 55(2) anti-avoidance context: Normally, inter-corporate dividends are received tax-free by a Canadian corporate shareholder (under the s. 112 dividend received deduction). Section 55(2) recharacterizes an inter-corporate dividend as a capital gain (in whole or in part) where one purpose of the dividend was to reduce the capital gain that would otherwise have arisen on a disposition of the shares at FMV. The butterfly manoeuvre navigates an exception in s. 55(3)(b) that permits asset butterflies in the context of genuine reorganizations.

Butterfly Transaction: A corporate reorganization that divides a corporation's assets among its shareholders on a proportionate basis by routing property through tax-free inter-corporate dividends and a subsequent distribution to shareholders. The butterfly exception in ITA s. 55(3)(b) permits the distribution to occur without triggering the s. 55(2) recharacterization, provided the distribution is pro rata among shareholders (or a group of arm's-length shareholders) and no undue concentration of value occurs.

Butterfly planning is highly technical, requiring expert tax counsel and careful attention to the specific conditions in s. 55(3.01) through (3.2), which impose restrictions on the types of property distributed and the post-butterfly activities of the parties.


Chapter 6: Surplus Stripping and Anti-Avoidance

Section 6.1: What Is Surplus Stripping?

Surplus stripping refers to strategies that convert corporate retained earnings (which would normally be paid out as dividends, subject to personal dividend tax) into capital gains eligible for the lower inclusion rate and potentially the LCGE. Because capital gains are taxed at 50% of the dividend rate (approximately), a $1 of corporate surplus extracted as a capital gain instead of a dividend produces meaningful tax savings.

The general framework of surplus stripping:

  1. A corporation has accumulated surplus (after-tax retained earnings)
  2. Through some reorganization, the shareholder disposes of shares or receives proceeds that are characterized as capital gains rather than dividends
  3. The LCGE potentially shelters the gain entirely

Canada’s tax legislation contains numerous specific anti-avoidance rules targeting surplus stripping, and GAAR serves as a backstop.

Section 6.2: Section 84.1 — Non-Arm’s Length Share Transfers

Section 84.1 applies when an individual transfers shares of a private corporation to a connected private corporation (one with which the individual does not deal at arm’s length). The rule prevents an individual from using an intermediary corporation to effectively extract corporate surplus as a capital gain (potentially sheltered by the LCGE) rather than as a dividend.

ITA s. 84.1 Deemed Dividend: Where an individual transfers shares of a subject corporation to an acquiring corporation that is connected to the subject corporation (not at arm's length), the paid-up capital of shares received by the individual from the acquiring corporation is reduced (PUC grind). Additionally, if the FMV of shares or other consideration received exceeds the greater of (a) the PUC of shares transferred and (b) the ACB of those shares (the "hard ACB"), a deemed dividend arises to the extent of the excess.

Hard ACB concept: For s. 84.1 purposes, an individual’s ACB of shares is reduced by any LCGE previously claimed in respect of those shares or shares substituted for them. This prevents the individual from using the LCGE to create an elevated ACB that could then be used as a shield against s. 84.1.

Example — Section 84.1: An individual holds QSBC shares with ACB = \$50,000 and PUC = \$1,000. FMV of the shares = \$1,000,000. The individual previously claimed \$300,000 of LCGE on a disposition of a predecessor of these shares. The individual sells the shares to a corporation she controls for \$1,000,000 in exchange for a \$1,000,000 note.

Hard ACB = $50,000 − $300,000 = ($250,000) → floored at nil = $0.

Deemed dividend = $1,000,000 (FMV of consideration) − max($1,000 PUC, $0 hard ACB) = $999,000.

The individual receives a deemed dividend of $999,000 rather than a capital gain, eliminating the surplus stripping benefit.

Section 6.3: Section 246.1 — Deemed Benefit

The relatively newer s. 246.1, introduced in 2016, is designed to address surplus stripping through value extraction where a corporation confers a benefit on a related party that is not caught by the specific anti-avoidance rules. It deems an amount to be a dividend received by the person who receives the benefit, to the extent it is not otherwise included in income.

Section 6.4: The General Anti-Avoidance Rule (GAAR) — Section 245

Section 245 of the ITA contains the General Anti-Avoidance Rule, which can override a technically compliant transaction if it constitutes an avoidance transaction that results in a misuse of the ITA or an abuse of the ITA read as a whole.

General Anti-Avoidance Rule (GAAR, ITA s. 245): A rule that allows the CRA to deny the tax benefit arising from any transaction (or series of transactions) that would otherwise produce a tax benefit if: (1) the transaction resulted in a tax benefit; (2) the transaction was an avoidance transaction (no bona fide non-tax purpose, or the primary purpose was to obtain the benefit); and (3) the transaction resulted in a misuse of any provision of the ITA or an abuse of the ITA read as a whole. The 2023 amendments also introduced a 25% penalty on GAAR-denied benefits in some circumstances and an extended reassessment period.

GAAR analysis — three-part test:

  1. Tax benefit: Any reduction, avoidance, or deferral of tax. Broadly defined.
  2. Avoidance transaction: The transaction (or any step in a series) resulted in the tax benefit and was not undertaken primarily for bona fide non-tax purposes.
  3. Abuse or misuse: The transaction frustrated the object, spirit, or purpose of the specific provision relied upon, or of the ITA read as a whole.

Where GAAR applies, the CRA can re-determine tax as if the transaction had not occurred, or on any other basis consistent with the proper application of the ITA. The taxpayer bears the burden of establishing bona fide non-tax purpose; the CRA bears the burden of establishing abuse.

Amended GAAR (2023 Budget): The 2023 Federal Budget significantly amended GAAR, effective for transactions entered into on or after January 1, 2024. Key changes include: (a) the “primary purpose” test is replaced with a lower threshold — any purpose of obtaining the benefit is sufficient; (b) a 25% penalty applies to GAAR-denied benefits absent a voluntary disclosure; and (c) a 3-year extension of the normal reassessment period. These changes make GAAR a more potent tool for the CRA.


Chapter 7: International Taxation

Section 7.1: Residence and Source of Income

Canadian income tax is based primarily on residence. A person resident in Canada is taxed on their worldwide income (ITA s. 2(1)). A non-resident is taxed only on Canadian-source income: income from employment in Canada, income from business carried on in Canada, and taxable capital gains from the disposition of taxable Canadian property (ITA s. 2(3)).

Residency for Individuals: An individual is resident in Canada if they are ordinarily resident in Canada (common law test — significant residential ties including home, spouse, dependants, social memberships). An individual who sojourns in Canada for 183 or more days in a calendar year is deemed resident for that year (ITA s. 250(1)). Dual residency is resolved by the tie-breaker rules in Canada's tax treaties.
Residency for Corporations: A corporation is resident in Canada if it was incorporated in Canada after April 26, 1965, or if it carries on business in Canada and was either incorporated in Canada before that date or the central management and control of the corporation is exercised in Canada (ITA s. 250(4)).

Taxable Canadian Property (TCP): Non-residents who dispose of TCP are subject to Canadian capital gains tax. TCP includes real property situated in Canada, shares of private corporations deriving more than 50% of their value from Canadian real property or resource property, and various other categories. Under s. 116, the purchaser must withhold from the purchase price and remit to the CRA unless the non-resident has obtained a clearance certificate.

Section 7.2: Withholding Taxes

Canada imposes Part XIII withholding tax on passive income paid or credited to non-residents (ITA s. 212). The standard withholding rate is 25%, but most of Canada’s tax treaties reduce this rate significantly.

Payment TypeDomestic RateCanada-US Treaty RateCanada-UK Treaty Rate
Dividends25%15% (5% if 10%+ shareholder)15% (5% if 10%+ shareholder)
Interest25%0%0%
Royalties25%0% (10% for certain types)0%
Management fees25%0% (may be exempt)0%
Rent25%25% (no treaty reduction)25%

The treaty rates apply when the recipient is a “resident” of the treaty partner country and the treaty’s limitation on benefits provisions are satisfied.

Treaty Shopping and the Principal Purpose Test (PPT): Canada’s tax treaties, consistent with the OECD BEPS Action 6 recommendations, now include the Principal Purpose Test. If one of the principal purposes of an arrangement is to obtain a treaty benefit, the benefit may be denied. This targets structures where a non-resident routes income through a treaty-partner country without genuine business presence there.

Section 7.3: Foreign Tax Credits

Canadian residents who pay income tax in a foreign jurisdiction on foreign-source income may claim a foreign tax credit (FTC) under ITA ss. 126(1) (non-business income) or 126(2) (business income) to reduce their Canadian tax on that same income.

Foreign Tax Credit (ITA s. 126): A credit available to Canadian residents for income or profits taxes paid to a foreign government. The credit is limited to the lesser of: (a) the foreign tax paid; and (b) the Canadian tax otherwise payable on the foreign-source income. The limitation prevents foreign tax from offsetting Canadian tax on Canadian-source income.

Business income FTC (s. 126(2)): The credit for foreign business income taxes is calculated on a country-by-country basis. Excess credits in one country may be deducted as a business expense (under s. 20(12)) rather than credited. The FTC system therefore aims for the lesser of the foreign rate and the Canadian rate to apply, with no refund for foreign tax exceeding Canadian liability.

Non-business income FTC (s. 126(1)): This credit applies to foreign taxes on passive income (interest, dividends, rents, royalties). The credit is limited to 15% of the gross foreign income for certain categories. Excess foreign tax above this limit is deductible as an expense under s. 20(11) rather than a credit.

Section 7.4: Controlled Foreign Affiliates and FAPI (ITA s. 95)

Canadian corporations and individuals investing in foreign corporations face the foreign affiliate rules. A foreign affiliate is a non-resident corporation in which the Canadian taxpayer (directly or indirectly) owns at least 1% of any class of shares, and together with related persons, owns at least 10%.

Controlled Foreign Affiliate (CFA): A foreign affiliate that is controlled by the Canadian taxpayer (and related persons). A CFA is distinguished from a non-controlled foreign affiliate (NCFA). The income of a CFA is subject to the Subpart F-equivalent rules in Canada: certain passive income (FAPI) is included in the Canadian parent's income on an accrual basis.

Foreign Accrual Property Income (FAPI): FAPI is broadly defined as passive income earned by a CFA — including interest, dividends from non-affiliates, royalties, rents, and income from a business that is not an active business. FAPI is included in the Canadian parent’s income for the year in which it accrues (even if not distributed), grossed up by the foreign accrual tax factor, and the corresponding foreign taxes paid (or deemed paid) by the CFA are credited against the Canadian tax (ITA s. 91).

Active business income exception: Income of a CFA that constitutes active business income is not FAPI and accumulates in the CFA’s exempt surplus or taxable surplus accounts. Dividends paid from exempt surplus are received tax-free by the Canadian parent; dividends from taxable surplus carry a deduction under s. 113 equal to the underlying foreign taxes.

Surplus accounts: A foreign affiliate maintains notional surplus accounts:

  • Exempt surplus: income from active businesses in treaty countries and previously taxed FAPI. Dividends from exempt surplus are deductible under s. 113(1)(a).
  • Taxable surplus: active business income from non-treaty countries. Dividends receive a partial deduction under s. 113(1)(b).
  • Pre-acquisition surplus: surplus existing when the affiliate was acquired. Dividends from this pool reduce the ACB of the shares.

Section 7.5: Thin Capitalization Rules

The thin capitalization rules in ITA ss. 18(4)–18(6) restrict the deductibility of interest paid by a Canadian corporation to specified non-residents (shareholders holding 25%+ of any class of shares) where the ratio of outstanding interest-bearing debt to “equity” exceeds 1.5:1.

Thin Capitalization (ITA s. 18(4)): Where the total outstanding interest-bearing debt owed by a Canadian corporation to specified non-residents exceeds 1.5 times the "equity amount" of the corporation, the interest paid on the excess debt is not deductible. The disallowed interest is then re-characterized as a deemed dividend subject to Part XIII withholding tax (ITA s. 214(16)).

The equity amount is defined in s. 18(5) as the corporation’s retained earnings plus paid-up capital plus contributed surplus (calculated on a tax basis). Planning to stay within the 1.5:1 ratio typically involves injecting equity, capitalizing certain amounts as equity (preferred shares vs. debt), and managing the timing of debt repayments.


Chapter 8: GST/HST — Comprehensive Framework

Section 8.1: Structure of the GST/HST System

Canada’s value-added tax (VAT) is the Goods and Services Tax (GST) at 5% federally, with provincial components creating the Harmonized Sales Tax (HST) in participating provinces (Ontario: 13%, Nova Scotia: 15%, New Brunswick: 15%, P.E.I.: 15%, Newfoundland and Labrador: 15%, B.C.: 12% but reverted to 5% GST only in 2013 — advisors should confirm current rates). Quebec administers its own QST (9.975%) separately through Revenu Québec.

The GST/HST is a destination-based consumption tax collected by registrants throughout the supply chain, with each registrant remitting tax net of input tax credits (ITCs) for tax paid on business inputs. This creates a “flow-through” effect so that only the final consumer bears the full tax.

Supply: Any provision of property or service in any manner including sale, transfer, barter, exchange, licence, rental, lease, gift, or disposition (ETA s. 123(1)). Supplies are classified as taxable (standard-rated or zero-rated) or exempt. The classification drives the GST/HST treatment.

Section 8.2: Taxable vs. Exempt vs. Zero-Rated Supplies

CategoryGST/HST CollectedITC AvailableExamples
Taxable (standard-rated)YesYesMost goods and services
Zero-ratedNo (0% rate)YesExports, basic groceries, prescription drugs, agricultural supplies
ExemptNoNoHealth care, educational services, financial services, residential rents

Zero-rated supplies are technically taxable supplies but at 0%. The registrant does not collect GST/HST from the recipient but can still claim ITCs on inputs used to make zero-rated supplies. This is important for exporters and the food industry.

Exempt supplies are not subject to GST/HST at all, and the supplier cannot claim ITCs on inputs used to make exempt supplies. This creates an embedded, unrecoverable tax cost for providers of exempt services (e.g., banks, hospitals, landlords of residential property).

Section 8.3: Registrants and Registration

A person who makes taxable supplies in the course of commercial activity must register for GST/HST when their total annual taxable supplies (including those of associated persons) exceed $30,000 (ETA s. 240). Small suppliers below the threshold may voluntarily register.

Commercial activity: A business or adventure or concern in the nature of trade, excluding activities carried on without a reasonable expectation of profit, and excluding the making of exempt supplies.

Registrant obligations: Once registered, a person must:

  • Collect GST/HST on all taxable supplies
  • File periodic GST/HST returns (monthly, quarterly, or annually depending on sales volume)
  • Remit net tax (tax collected less ITCs)
  • Maintain adequate books and records

Section 8.4: Input Tax Credits

A registrant may claim an ITC equal to the GST/HST paid on property and services acquired for use in commercial activities (ETA s. 169). The ITC mechanism eliminates the cascading tax that would otherwise result from taxing intermediate business purchases.

Input Tax Credit (ITC): A credit available to a GST/HST registrant for tax paid on inputs acquired for use primarily in commercial activities. The ITC equals the GST/HST paid (or payable) on the acquisition, prorated if the input is used for both commercial and non-commercial purposes.

Proration rules: Where a registrant acquires an input used partly in commercial activities and partly in exempt or personal activities, only the commercial portion of the GST/HST qualifies for an ITC. The proration must be reasonable and documented.

Restrictions on ITCs: Certain expenditures are restricted. For example, only 50% of the GST/HST on meals and entertainment qualifies for an ITC (consistent with the income tax 50% limitation under ITA s. 67.1). Capital real property used partly commercially may require a special method.

Section 8.5: Exempt Supplies — Special Sectors

Financial services: Most financial services are exempt under Schedule V, Part VII of the ETA, including insurance, deposit-taking, securities brokering, and lending. Financial institutions cannot claim ITCs on inputs used for exempt financial services, creating a significant embedded tax cost. However, financial institutions are subject to special rules (the “financial institution” provisions) that require annual adjustments and use of approved methods for ITC allocation.

Health care: Most health care services provided by regulated health professionals are exempt (Schedule V, Part II). However, cosmetic surgery, teeth whitening, and other non-medically necessary procedures are taxable.

Educational services: Tuition for courses leading to a certificate or diploma is exempt (Schedule V, Part III). Private tutoring is generally taxable unless the educational institution qualifies.

Real property:

  • Sale of new residential real property: taxable, but buyer may claim a new housing rebate reducing effective rate
  • Sale of used residential property: exempt
  • Commercial real property sales: taxable (unless election under ETA s. 167 for going-concern)
  • Long-term residential rents: exempt
  • Short-term accommodation (hotels, Airbnb): taxable

Section 8.6: The Quick Method and Other Simplified Options

Registrants with annual taxable supplies under $400,000 may elect the Quick Method (ETA s. 227). Under the Quick Method, the registrant remits a specified percentage of total revenues (including GST/HST collected) rather than computing actual ITCs. This simplifies bookkeeping but may result in more or less tax than the regular method depending on the ITC ratio.

Quick Method remittance rates for 2025 (approximate):

  • Service businesses: 8.8% of GST-included revenues (in provinces with GST only); higher rates for HST provinces
  • Businesses that purchase goods for resale: lower rates apply

Chapter 9: Partnership Taxation

Section 9.1: The Conduit Principle

A partnership is not a taxpayer for Canadian income tax purposes — it is a conduit. Under ITA s. 96, partnership income (or loss) is calculated at the partnership level as if the partnership were a separate person, and is then allocated to each partner in accordance with the partnership agreement. Each partner includes their allocated share of income or loss in their own return for the calendar year in which the partnership’s fiscal year ends.

Partnership (ITA s. 96): A relationship between two or more persons carrying on business in common with a view to profit. For tax purposes, a partnership computes its income as if it were a separate taxpayer, then allocates that income to partners who include it in their own returns. The partnership itself does not pay tax.

Fiscal year of a partnership: A partnership that has a member who is an individual must generally use December 31 as its fiscal year end (ITA s. 249.1), unless it elects an alternative fiscal year (which results in a “stub period” inclusion formula). Partnerships with only corporate partners can use any fiscal year.

Section 9.2: Adjusted Cost Base of a Partnership Interest

The ACB of a partner’s interest in a partnership is a running calculation that tracks the partner’s economic investment. It begins at the cost of the interest and is adjusted annually.

ACB increases (ITA s. 53(1)(e)):

  • Partner’s share of partnership income (including capital gains and FAPI)
  • Capital contributions to the partnership
  • Partner’s share of any taxable capital gains of the partnership

ACB decreases (ITA s. 53(2)(c)):

  • Partner’s share of partnership losses (including capital losses)
  • Distributions of money or property from the partnership
  • Partner’s share of CCA (UCC deductions) taken at the partnership level
  • Partner’s share of resource deductions
Example — Partnership ACB Calculation: Partner A contributes \$100,000 to Partnership AB on January 1. In Year 1, the partnership earns \$30,000 of business income and pays A their 50% share = \$15,000. The partnership also claims CCA of \$10,000; A's share = \$5,000. No distributions are made.

A’s ACB at end of Year 1: Opening ACB: $100,000

  • Income allocation: $15,000 − CCA allocation: $5,000 = Closing ACB: $110,000

If A later sells the partnership interest for $120,000, capital gain = $120,000 − $110,000 = $10,000.

Section 9.3: At-Risk Rules

A partner’s deductible share of partnership losses is limited to their at-risk amount — roughly the ACB of the partnership interest less any amounts the partner is protected from economic loss (e.g., guaranteed loans, amounts owing to the partnership) (ITA s. 96(2.1)–(2.7)).

At-Risk Amount (ITA s. 96(2.2)): The amount by which the ACB of the partner's partnership interest exceeds the sum of (a) any amounts owing by the partner to the partnership, and (b) any amounts that would reduce the partner's economic exposure (e.g., guarantees from another party). Losses in excess of the at-risk amount are suspended and carried forward as "limited partnership losses."

Limited partnership losses: Where a partner (particularly a limited partner) has deductible losses exceeding the at-risk amount, the excess is classified as a limited partnership loss and may only be deducted in a year when the partner’s at-risk amount is positive (ITA s. 111(1)(e)).

Section 9.4: Partnership vs. Corporation — Planning Considerations

Choosing between carrying on business in partnership vs. corporate form involves weighing several factors:

FactorPartnershipCorporation
Tax rates on incomeFlow-through at personal ratesLow CCPC rate (9% + provincial) with deferral
LossesFlow directly to partners immediatelyTrapped inside corporation until future profits
LiabilityUnlimited for general partnersLimited to investment
Capital gains exemptionPartners may access LCGE on qualifying propertyMust hold qualifying shares
ComplexitySimplerMore administrative requirements
TOSI exposurePartners’ family members may receive partnership incomeTOSI applies to dividends from related businesses

Partnerships are often preferred in the start-up phase (losses immediately usable by partners who have other income) and in professional practices where incorporation is restricted. Once a business becomes consistently profitable, incorporation typically becomes more advantageous due to the significant SBD deferral.

Section 9.5: Conversion of Partnership to Corporation

When a profitable partnership decides to incorporate, the partners can transfer their partnership interests to a new corporation under ITA s. 85, electing a tax-deferred transfer. Alternatively, the partnership transfers its underlying assets directly to the corporation, with each partner electing under s. 85 for their proportionate share. The mechanics must be carefully structured to ensure the s. 85 election is valid and that the GST/HST going-concern election under ETA s. 167 is made where applicable.


Chapter 10: Trust Taxation

Section 10.1: Trusts as Taxpayers

A trust is treated as an individual for Canadian income tax purposes (ITA s. 104(2)) and files its own T3 return. Trusts can be inter vivos (created during the settlor’s lifetime) or testamentary (arising on death under a will or intestacy).

Types of trusts relevant to tax planning:

  • Inter vivos discretionary trust: The most common vehicle in private corporation planning. The trustee has discretion over which beneficiaries receive income and capital.
  • Alter ego trust: An inter vivos trust established by a settlor aged 65 or older; only the settlor is entitled to income and capital during their lifetime. Avoids probate on death.
  • Spousal or common-law partner trust: A testamentary trust under which the surviving spouse is entitled to all income during their lifetime. Qualifying for rollover on death under ITA s. 70(6).
  • Qualifying disability trust (QDT): A testamentary trust eligible for graduated rate taxation (rather than top marginal rate) where a beneficiary qualifies for the disability tax credit.
  • Employee Benefit Trust / Employee Life and Health Trust (ELHT): Specific trusts used for group benefit plans.

Section 10.2: 21-Year Deemed Disposition Rule

The 21-year rule prevents the indefinite deferral of accrued capital gains within a trust. Under ITA s. 104(4), a trust is deemed to have disposed of all its capital property (other than certain exempt properties) at FMV every 21 years from the date the trust was created (or from January 1, 1972, for pre-1972 trusts). The deemed proceeds are equal to FMV; the trust recognizes any accrued capital gain and pays tax at the trust’s marginal rate.

21-Year Deemed Disposition (ITA s. 104(4)): A deemed disposition of a trust's capital property at FMV occurring every 21 years. The trust recognizes capital gains (and recapture on depreciable property) and pays tax. Careful planning is required to avoid a large unexpected tax bill on the 21st anniversary of the trust's creation.

Planning strategies to address the 21-year rule:

  1. In-kind distribution before the anniversary: Under ITA s. 107(2), a trust can distribute capital property to a Canadian-resident beneficiary on a tax-deferred basis (rolled out at the trust’s ACB). The beneficiary acquires the property at the trust’s cost, deferring the gain to the beneficiary’s own future disposition. This must be done before the 21-year anniversary.

  2. Annual allocation of capital gains: Where the trust has capital gains, it can designate those gains as payable to beneficiaries under ITA s. 104(21), which causes the gain to be included in the beneficiary’s income (rather than the trust’s). This uses the beneficiary’s personal tax rates and potentially their LCGE.

  3. Trust winds up on anniversary: Sometimes the most practical solution is to plan for the trust to distribute all its assets to beneficiaries before the 21st anniversary, using the s. 107(2) rollout.

Section 10.3: Trust Taxation — Income Allocation and the 21-Year Trap

Trusts can flow income to beneficiaries through the mechanism of a payable designation. Where income of a trust is “payable” to a beneficiary in a year (i.e., the trustee exercises discretion to pay or is obligated to pay it), that income is deducted from the trust’s income under ITA s. 104(6) and included in the beneficiary’s income under ITA s. 104(13). The trust’s rate of tax applies to any income retained in the trust.

High trust tax rate: Inter vivos trusts (other than specified trusts) are taxed at the top personal marginal rate on all retained income. This eliminates any rate arbitrage of holding income inside an inter vivos trust. Testamentary trusts that qualify as graduated rate estates (GREs) are taxed at graduated rates for up to 36 months after death; qualifying disability trusts (QDTs) also receive graduated rates.

Attribution rules: Income earned by a trust may be attributed back to the settlor where the settlor retains certain powers or interests in the trust. The principal attribution rules for trusts are in ITA ss. 75(2) (revocable trusts) and 74.3 (trusts benefiting spouses or minor children of the contributor). Care must be taken in trust drafting to avoid inadvertently triggering attribution.

Section 10.4: Preferred Beneficiary Election

The preferred beneficiary election (PBE) under ITA s. 104(14) allowed a trust and a disabled or infirm beneficiary to jointly elect to have income accumulated in the trust included in the beneficiary’s income (enabling use of the beneficiary’s low marginal rate), even though the income was not actually paid out. This election was significantly restricted in 1996 and is now available only in very limited circumstances (where the beneficiary is entitled to the disability tax credit). Advisors working on trust documents for disabled family members should be familiar with the current PBE conditions.

Section 10.5: Death of a Taxpayer — Interaction with Trusts and Estate Planning

On death, a Canadian resident taxpayer is deemed to have disposed of all capital property immediately before death at its FMV (ITA s. 70(5)). This creates a deemed capital gain (or loss) in the terminal return.

Spousal rollover (s. 70(6)): Where property passes to a surviving spouse or common-law partner (or a qualifying spousal trust), the disposition is deemed to occur at the property’s ACB, deferring the tax until the spouse (or trust) ultimately disposes of the property.

RRSP/RRIF on death: The FMV of an RRSP or RRIF is included in the deceased’s income in the year of death unless it is transferred (rolled over) to:

  • A surviving spouse’s registered account (RRSP or RRIF)
  • An RDSP for a financially dependent disabled child or grandchild
  • An annuity for a financially dependent minor child or grandchild

Post-mortem tax planning: Where a private corporation holds significant retained earnings and the deceased held shares, the estate faces a double-tax problem: the deemed disposition on death triggers a capital gain, and the eventual distribution of after-tax corporate surplus to the estate is also taxed. Several planning strategies address this:

  1. Pipeline planning: The estate transfers the deceased’s shares to a new corporation via s. 85 rollover. The new corporation amalgamates with the operating company (s. 87), creating a high ACB note payable to the estate. The estate receives repayment of the note tax-free (return of ACB). This pipeline strategy has been validated by the CRA with certain conditions but GAAR risk remains.

  2. Loss carry-back under s. 164(6): The estate may recognize a capital loss on the actual disposition of the shares, which can be carried back against the deceased’s deemed capital gain on the terminal return (up to the year of death), subject to the one-year carry-back limitation for terminal return losses.


Chapter 11: Tax Policy — BEPS, Pillar Two, and the Digital Economy

Section 11.1: OECD Base Erosion and Profit Shifting (BEPS)

The OECD/G20 Base Erosion and Profit Shifting (BEPS) project, launched in 2013 and producing 15 action plans by 2015, fundamentally reshaped international tax norms. BEPS refers to tax planning strategies that exploit gaps and mismatches in tax rules to artificially shift profits to low-tax or no-tax jurisdictions.

Key BEPS action plans and their Canadian implementation:

BEPS ActionTopicCanada’s Response
Action 2Hybrid mismatch arrangementsITA s. 18.4, anti-hybrid rules (2022)
Action 3CFC rules strengtheningExisting FAPI rules considered adequate
Action 4Interest deductibilityEIFEL rules (s. 18.2, 2023)
Action 5Harmful tax practicesEnhanced information exchange
Action 6Treaty abuse / PPTMultilateral Instrument (MLI)
Action 7Permanent establishmentTreaty updates
Action 13Country-by-country reportingITA s. 233.8, effective 2016
Action 15Multilateral instrumentMLI signed 2017, in force 2019

EIFEL rules (Excessive Interest and Financing Expenses Limitation, ITA s. 18.2): Introduced in 2023 to implement BEPS Action 4, the EIFEL rules limit the deductibility of net interest and financing expenses to 40% of adjusted taxable income (ATI) for taxation years beginning before 2024 and 30% for taxation years beginning in 2024 and later. Unused capacity may be carried forward. Groups of Canadian-affiliated entities may elect to apply the rules on a group basis. Small businesses with interest and financing expenses below $1 million are exempt.

Section 11.2: Pillar Two — Global Minimum Tax

The OECD’s Pillar Two framework, agreed upon in 2021 and now being implemented by more than 140 jurisdictions, establishes a global minimum effective tax rate of 15% for multinational enterprise (MNE) groups with annual revenues exceeding €750 million.

Pillar Two — Global Anti-Base Erosion (GloBE) Rules: A set of OECD model rules designed to ensure that large MNEs pay a minimum effective tax rate of 15% in each jurisdiction in which they operate. Two primary charging rules apply: the Income Inclusion Rule (IIR), which allows the parent jurisdiction to "top-up" the tax on a subsidiary's income where the subsidiary is taxed below 15%; and the Undertaxed Profits Rule (UTPR), which is a backstop allowing other group members' jurisdictions to collect top-up tax not collected under the IIR.

Canada’s Pillar Two implementation: Canada enacted the Global Minimum Tax Act (GMTA) in 2024, effective for fiscal years beginning on or after December 31, 2023. The GMTA implements the IIR as a Qualifying Domestic Minimum Top-up Tax (QDMTT) and the IIR for outbound Canadian MNEs. The UTPR backstop is expected to apply from 2025.

Effective tax rate (ETR) calculation under GloBE: The ETR for Pillar Two purposes is calculated on a jurisdiction-by-jurisdiction basis as:

\[ ETR = \frac{\text{Adjusted Covered Taxes}}{\text{GloBE Income}} \]

Where adjusted covered taxes is income tax actually paid and accrued (adjusted for temporary differences and deferred tax), and GloBE income is accounting income (IFRS) adjusted under the GloBE rules. If the ETR falls below 15%, a top-up tax equal to \((15\% - ETR) \times \text{GloBE Income}\) applies.

Planning implications for Canadian groups: Large Canadian MNEs must now model their GloBE ETR by jurisdiction and identify where they fall below the 15% floor. Key planning areas include the substance-based income exclusion (a carve-out for payroll costs and tangible assets used in the jurisdiction, reducing GloBE income), deferred tax timing differences (which affect covered taxes), and the impact of preferred tax regimes on the ETR.

Section 11.3: Digital Services Tax

Canada enacted the Digital Services Tax Act (DSTA) in 2024, imposing a 3% tax on digital services revenues (defined broadly to include targeted online advertising, online marketplace services, social media platform services, and user data revenues) earned from Canadian users. The DSTA applies to businesses with global revenues over €750 million and Canadian digital services revenues over CAD $20 million.

The DSTA is controversial in the international context, as the United States has objected to digital services taxes imposed by Canada and other countries, viewing them as discriminatory against US technology companies. The OECD had anticipated resolving the digital economy tax issue through Pillar One (profit reallocation to market jurisdictions), but delays in Pillar One implementation led Canada to proceed unilaterally.

Pillar One: Pillar One of the OECD framework proposes to reallocate a portion of the profits of the largest and most profitable MNEs (those with global revenues > €20 billion and profitability > 10%) to market jurisdictions where revenues are generated, regardless of physical presence. As of 2025, Pillar One’s multilateral convention remains unfinished, with significant implementation uncertainty.


Chapter 12: The Problem-Solving Process for Tax — Case Analysis Framework

Section 12.1: Four-Stage Framework

Professional tax advice requires a structured analytical methodology. The Problem-Solving Process (PSP) for Tax involves four stages:

Stage 1 — Assess the Situation: Read the fact pattern thoroughly. Identify the client, the relevant taxation year(s), the legal entities involved, and the client’s objectives (minimize tax, defer tax, estate objectives, sale proceeds). Flag any ambiguities or missing information.

Stage 2 — Identify the Issues: Group related issues logically (e.g., all issues related to compensation, all related to the upcoming share sale). Prioritize by materiality. For each issue, state the relevant ITA provision(s) and the analytical approach to be applied.

Stage 3 — Analyze the Issues: Apply the law to the facts. For each identified issue, state the applicable provision, apply it to the specific client facts, perform any required calculations, and reach a conclusion. Consider alternative treatments and anti-avoidance rules (GAAR, specific anti-avoidance provisions).

Stage 4 — Advise and Recommend: Integrate the issue-by-issue analysis into a cohesive recommendation. Quantify the tax savings or costs where possible. Use plain language appropriate for the client, but maintain professional precision. Where relevant ITA references strengthen the advice, cite them.

Section 12.2: Data Analytics in Tax Practice

Modern tax practice increasingly incorporates data analytics tools to process large volumes of transactional data, identify patterns, and perform tax calculations at scale. In the context of AFM 462, students learn to use Excel and other tools to:

  • Build integration models comparing salary vs. dividend scenarios across provinces and income levels
  • Automate the computation of at-risk amounts for partners with complex annual adjustments
  • Model EIFEL limitations across multiple years with loss carryforward tracking
  • Build Pillar Two ETR waterfalls showing GloBE income adjustments and top-up tax calculations
  • Compute CDA balances with running capital gain and life insurance tracking

The ability to present quantitative analysis in a structured Excel workbook — with clearly labeled inputs, formulas with explanatory footnotes, and cross-references to the written memorandum — is a critical professional skill.

Section 12.3: Communication — The Tax Memorandum

A professional tax memorandum must be organized, concise, and understandable by a reader who may not have the same depth of tax knowledge as the author. Standard professional memorandum structure includes:

  1. Introduction / Purpose: One paragraph summarizing what the memo addresses and for whom.
  2. Background Facts: Brief recitation of the relevant facts. Do not repeat all facts — only those material to the issues.
  3. Issues: A numbered list of issues identified.
  4. Analysis: The main body, organized by issue. Each issue section: states the legal rule, applies it to the facts, concludes.
  5. Recommendations: Integrated advice flowing from the analysis. Prioritized and actionable.
  6. Appendices: Supporting quantitative calculations in Excel, cross-referenced in the memo.

Writing principles for tax analysis:

  • State the rule before applying it: “Under ITA s. 125(1), a CCPC may deduct…”
  • Apply the rule explicitly to the specific facts: “Because [Client] is a CCPC earning active business income of…”
  • Draw an explicit conclusion for each issue: “Therefore, [Client] is/is not entitled to…”
  • Use headings to organize a long memorandum
  • Write in full sentences for final assessments; abbreviated sentences are acceptable for midterm submissions per the course standards

Chapter 13: Comprehensive Review and Integration

Section 13.1: Owner-Manager Planning Integration

The disciplines covered in AFM 462 do not operate in isolation. An owner-manager planning a corporate sale, for example, faces a web of interconnected issues:

Comprehensive Planning Scenario:

Facts: Li Wei, age 55, has operated WeiBuild Inc. (a CCPC) for 20 years, providing construction services in Ontario. WeiBuild has retained earnings of $3,000,000 and the shares currently have an FMV of $4,500,000 and an ACB/PUC of $100,000. Li’s spouse, Chen, age 52, holds 30% of the common shares through a family trust established 15 years ago. They have three adult children. A prospective buyer has offered $4,500,000 for 100% of the WeiBuild shares. Li wants to minimize combined family tax.

Issues to identify:

  1. QSBC share eligibility: Is WeiBuild an SBC at disposition? Are the 24-month holding and asset composition tests met?

  2. LCGE availability: Li and the trust beneficiaries may each shelter up to $1,016,602 (2025) of capital gain. With the family trust holding 30%, multiple beneficiaries can access their own LCGE. How much of the $4,400,000 capital gain (= $4,500,000 − $100,000) can be sheltered?

  3. TOSI and the family trust: Does TOSI apply to dividends paid by the trust to the adult children beneficiaries? If the trust allocates the capital gain to adult beneficiaries, is the capital gain subject to TOSI? (Note: under TOSI, split income includes certain capital gains from share dispositions.)

  4. s. 84.1 and the proposed structure: If the buyer is not arm’s length (e.g., a corporation controlled by Li’s children), would s. 84.1 apply to grind PUC and create a deemed dividend?

  5. Pre-sale estate freeze: Should a freeze have been done earlier to multiply LCGEs? If not yet done, is there time for a partial freeze before closing?

  6. HST on the share sale: Share sales are generally exempt from GST/HST as financial services. No HST on the share consideration.

  7. 21-year rule for the family trust: The trust is 15 years old. If not dissolved before year 21, the trust faces a deemed disposition. However, the upcoming sale proceeds to beneficiaries before year 21 effectively addresses this exposure.

Section 13.2: Key Anti-Avoidance Principles Summary

Anti-avoidance in Canadian tax operates on multiple levels:

Chapter 14: Financial Reporting for Income Tax (ASPE Section 3465)

Section 14.1: Overview of Tax Accounting Under ASPE

Private enterprises in Canada following Accounting Standards for Private Enterprises (ASPE) apply Section 3465 — Income Taxes. Section 3465 uses the temporary difference approach, recognizing future income tax assets and liabilities for differences between the tax base and carrying amount of assets and liabilities.

Temporary Difference: A difference between the carrying amount of an asset or liability on the balance sheet and its tax base (the amount attributed to that asset or liability for tax purposes). Temporary differences reverse in future periods and give rise to future income tax assets or liabilities. Temporary differences are contrasted with permanent differences — items that enter accounting income but never enter taxable income (e.g., non-deductible 50% of meals and entertainment), which do not give rise to future tax assets or liabilities.

Future income tax asset arises when the tax base of an asset exceeds its carrying amount (e.g., when CCA is claimed faster than accounting depreciation, the UCC exceeds the net book value — no, wait: when CCA is faster, UCC < NBV — the tax base of the asset (UCC) is lower than accounting carrying value, creating a deferred tax liability). A future income tax asset arises for deductible temporary differences: warranty liabilities deductible only when paid, unrealized capital losses, loss carryforwards.

Future income tax liability arises for taxable temporary differences: CCA excess over accounting amortization creates a lower UCC (tax base) than NBV (carrying amount), meaning future taxable income will exceed future accounting income when the asset is used or sold.

Section 14.2: Key Differences — Accounting Income vs. Taxable Income

ItemAccounting TreatmentTax Treatment
Amortization/depreciationPer GAAP useful lifeCCA at prescribed ITA Schedule II rates
Warranty expenseAccrued when product soldDeductible when paid
Reserves and provisionsAccrued on balance sheetGenerally not deductible until realized (ITA s. 20(1)(m))
Gains on disposalBook gain (proceeds − NBV)Capital gain (proceeds − ACB)
Club dues, entertainment100% expensed50% deductible (ITA s. 67.1)
Political contributionsExpenseNon-deductible (ITA s. 18(1)(n))
Fines and penaltiesExpenseNon-deductible (ITA s. 67.6)
Stock-based compensationExpensed per ASPE 3870Generally deductible only when options exercised
Life insurance premiumsExpenseGenerally non-deductible (ITA s. 18(1)(a))
Capital dividends receivedPart of dividend incomeNon-taxable

The reconciliation from accounting net income before tax to taxable income (the “tax note” in financial statements) lists all these differences, enabling readers to understand the effective tax rate and the components of the deferred tax balance.

Section 14.3: Deferred Tax Measurement

Under ASPE Section 3465, future income tax assets and liabilities are measured using the tax rates and tax laws expected to apply when the temporary difference reverses. Where tax rate changes are substantively enacted at the balance sheet date, the new rates are applied to existing temporary differences.

Example — CCA Temporary Difference:

A CCPC acquires equipment on January 1, Year 1 for $500,000. Accounting amortization: straight-line over 10 years = $50,000/year. CCA rate: 20% declining balance.

Year 1:

  • Accounting NBV: $500,000 − $50,000 = $450,000
  • CCA (half-year rule in Year 1): $500,000 × 20% × 1/2 = $50,000. UCC = $450,000.
  • Temporary difference = $0 (by coincidence in this example)

Year 2:

  • Accounting NBV: $450,000 − $50,000 = $400,000
  • CCA: $450,000 × 20% = $90,000. UCC = $360,000
  • Temporary difference = carrying amount $400,000 − tax base $360,000 = $40,000 (taxable temp. diff.)
  • Future income tax liability = $40,000 × 26.5% (Ontario CCPC general rate) = $10,600

As the asset ages, accounting amortization remains $50,000/year while CCA declines, so the taxable temporary difference grows until the crossover point where CCA falls below accounting amortization (typically in later years).


Chapter 15: Exam Preparation and Synthesis

Section 15.1: Commonly Tested Areas

Based on the structure of AFM 462 and the CPA Competency Map for the CFE, the following areas receive the most emphasis in assessments:

  1. Owner-manager compensation planning — Salary vs. dividend integration, TOSI analysis, shareholder benefits and loans. These require both qualitative identification and quantitative comparison.

  2. Corporate rollovers — Section 85 elected amount constraints, boot rules, PUC consequences. Students often lose marks by failing to check all elected amount conditions simultaneously.

  3. Estate freeze — Section 86 mechanics, freeze valuation issues, GAAR risk on inflated valuations.

  4. QSBC share analysis — The three-condition test for QSBC shares must be applied systematically; the 24-month holding test and the 50%/90% asset tests are frequently tested.

  5. CDA and capital dividends — Building a CDA account balance from given facts; knowing which items increase and which decrease the CDA.

  6. GAAR — Three-part test, bona fide non-tax purpose analysis, misuse/abuse distinction. The 2023 GAAR amendments (lower purpose threshold, penalties) are testable.

  7. FAPI — Identifying whether income of a CFA is active business income (not FAPI) or passive (FAPI); surplus account implications.

  8. GST/HST — Classifying supplies as taxable, zero-rated, or exempt; ITC eligibility; registration thresholds; HST on real property transactions.

Section 15.2: Common Mistakes and How to Avoid Them

Pitfall 1 — s. 85 elected amount below boot: The elected amount cannot be less than the non-share consideration (boot) received. Students often set the elected amount at ACB without first checking that ACB exceeds the boot. If boot > ACB, the minimum elected amount is the boot, which will trigger a partial gain.
Pitfall 2 — Ignoring TOSI on family trust dividends: When a family trust pays a dividend to an adult child beneficiary, TOSI analysis is mandatory. Failure to consider whether the excluded business, excluded shares, or reasonable return exclusion applies will result in incomplete analysis.
Pitfall 3 — s. 84(3) deemed dividend and simultaneous capital loss: On a share redemption, both a deemed dividend and a capital gain/loss computation must be performed. Students often calculate only the deemed dividend or only the capital gain, not both.
Pitfall 4 — CDA: only private corporations: The CDA is a concept applicable only to private corporations (including CCPCs). Public corporations do not have a CDA. Ensure the entity is a private corporation before analyzing the CDA balance.
Pitfall 5 — Thin cap denominator: The 1.5:1 debt-to-equity ratio uses an "equity amount" defined specifically in ITA s. 18(5), not simply shareholders' equity from the balance sheet. The tax-based definition must be applied.

Section 15.3: CPA Competency Map Connections

AFM 462 covers CPA Competency Map areas that are directly tested on the CFE:

  • Tax 4.2 — Corporate tax provisions (CCPCs, SBD, CDA, inter-corporate dividends)
  • Tax 4.3 — Disposition of property (rollovers, capital gains exemption)
  • Tax 4.4 — Trusts and estates
  • Tax 4.5 — Partnerships
  • Tax 5.1 — Personal tax planning for owner-managers
  • Tax 6.1 — International tax (residence, withholding, foreign affiliates — at an introductory depth)
  • Tax 7.1 — GST/HST registration and compliance
  • Enabling Competency: Communication — Tax memorandum drafting (20% of assessment marks)

The Course specifically notes that its coverage is required CPA coverage for the Fall 2026 CFE. Students should review the CPA Competency Map alongside course materials to understand the expected depth of knowledge.

Section 15.4: Refundable Taxes — RDTOH and the Dividend Refund Mechanism

A feature of the CCPC regime that is heavily tested in owner-manager planning problems is the Refundable Dividend Tax on Hand (RDTOH) and the related dividend refund. These mechanisms ensure that investment income earned inside a CCPC does not enjoy a permanent tax advantage over investment income earned personally.

Why does refundable tax exist? When a CCPC earns passive investment income (interest, rents, non-eligible dividends from portfolio investments), the income is taxed at the top federal-provincial corporate rate — approximately 50.17% in Ontario (2025). Of that corporate tax, a portion is refundable to the corporation when it pays dividends to its shareholders. The refund is intended to “release” the extra corporate tax collected on investment income so that integration is maintained.

Two RDTOH pools (post-2018): The 2018 Budget created two separate RDTOH pools to address over-integration of eligible dividends:

Eligible RDTOH: The pool of refundable tax arising from eligible portfolio dividends received by the CCPC. An eligible RDTOH refund is triggered only when the corporation pays an eligible dividend to shareholders. This prevents a CCPC from obtaining a refund of eligible RDTOH by paying a non-eligible dividend (which would create an over-integration advantage).
Non-Eligible RDTOH: The pool of refundable tax arising from active business investment income (interest, rents, capital gains, and non-eligible dividends from connected corporations). A non-eligible RDTOH refund is triggered when the corporation pays either an eligible dividend or a non-eligible dividend.

Refundable rate: The RDTOH addition rate for investment income earned inside a CCPC is \(30\frac{2}{3}\%\) (approximately 30.67%) of aggregate investment income (AII). The refund rate is $1 for every $3 of dividends paid (i.e., 33.33% of dividends, up to the RDTOH balance).

Example — RDTOH and Dividend Refund:

WeiBuild Inc. earns $100,000 of interest income in its taxation year. Federal corporate tax on investment income: 38.67%. Provincial (Ontario): 11.5%. Total tax = 50.17% = $50,170.

Non-eligible RDTOH addition = $100,000 × 30.67% = $30,670.

Net tax cost to corporation (non-refundable portion) = $50,170 − $30,670 = $19,500 (approximately).

If WeiBuild pays a non-eligible dividend of $49,830 (after-corporate-tax income = $100,000 − $50,170 = $49,830), the dividend refund = $49,830 × 33.33% = $16,608 (limited to $30,670 RDTOH balance). The corporation receives $16,608 back from the CRA.

Net corporate tax retained after refund = $50,170 − $16,608 = $33,562.

Combined with personal tax on the $49,830 non-eligible dividend, integration should approximately equal the tax the individual would have paid on $100,000 of interest income personally.

General Rate Income Pool (GRIP): The GRIP is a notional account tracking income that has been taxed at the general corporate rate (rather than the SBD rate). Only CCPCs with a GRIP balance can pay eligible dividends (which carry the higher gross-up and DTC). The GRIP ensures that the more favourable eligible dividend treatment is only available for income that has borne the higher general corporate rate.

Section 15.5: Inter-Corporate Dividends and the s. 112 Deduction

When one Canadian corporation receives a dividend from another Canadian corporation, the receiving corporation generally deducts the dividend under ITA s. 112(1) — the inter-corporate dividend deduction. This prevents cascading corporate tax as dividends flow up through a corporate group.

Inter-Corporate Dividend Deduction (ITA s. 112(1)): A deduction available to a taxable Canadian corporation equal to dividends received from another taxable Canadian corporation. The deduction effectively exempts inter-corporate dividends from corporate-level tax, recognizing that the paying corporation's income was already taxed once.

Exceptions to the s. 112 deduction:

  • Stop-loss rules: Where shares are held as part of a dividend-stripping arrangement or where the s. 112 deduction would produce an artificial capital loss (ITA ss. 112(3)–(7)), the deduction may be reduced.
  • Section 55(2): As discussed in Section 5.6, an inter-corporate dividend may be recharacterized as a capital gain where one purpose of the dividend was to reduce a capital gain on shares. The s. 55 rules intersect with s. 112 to prevent tax-free stripping of corporate value into inter-corporate dividends.
  • Non-portfolio dividends: Dividends received by a corporation on shares held as inventory (rather than as capital property) are excluded from the s. 112 deduction and remain fully taxable as business income.

Section 15.6: Loss Utilization — Non-Capital and Capital Losses

Tax losses are valuable assets that require careful management in corporate planning. The ITA distinguishes several types of losses with different carryover periods and restrictions.

Non-capital losses (ITA s. 111(1)(a)): Losses from a business or property that exceed income in a year create a non-capital loss. Non-capital losses can be carried back 3 years and forward 20 years. They are deductible against any type of income (not limited to the same source).

Net capital losses (ITA s. 111(1)(b)): Capital losses exceeding taxable capital gains in a year create a net capital loss. Net capital losses can only be deducted against taxable capital gains. They can be carried back 3 years and forward indefinitely. On death, unused net capital losses can be applied against any income in the terminal year and the preceding year (ITA s. 111(2)).

Acquisition of control — loss restrictions (ITA s. 111(5)): When control of a corporation is acquired by a person or group, special restrictions apply:

  • Net capital losses: extinguished entirely (cannot be carried forward past the acquisition date)
  • Non-capital losses: restricted to income from the same or similar business; unused losses from businesses that ceased to operate before the acquisition are also restricted
  • The “same business” test is applied broadly by the CRA, requiring the loss business to continue operating or to be revived

Loss restriction event: The 2013 rules extended the acquisition-of-control loss restriction framework to apply not only to corporations but also to trusts that undergo a “loss restriction event” (acquisition of majority interest in the trust).
