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.

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 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.

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, reducing its taxable income dollar-for-dollar. Salary creates earned income for RRSP contribution room, 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.

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.

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.

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.

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.
• 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 in the current or any five prior 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.

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.

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.

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.

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 (e.g., automobile standby charges and operating expense benefits have specific calculation rules).

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. An operating expense benefit of $0.33 per kilometre 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.
• Low-interest loans: Employment-related loans at below-prescribed rates trigger a taxable benefit equal to the difference between prescribed and actual rates.

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 intersects with corporate and personal tax planning in several important ways.

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, the nature of services provided by the owner-manager personally to third parties (versus through the corporation) can affect which entity charges and collects 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.

When a corporation realizes a capital gain, only 50% is included in taxable income (the taxable capital gain). The remaining 50% (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.

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.

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.

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 $1,016,602 (indexed annually). For QSBC shares and farming/fishing property, the exemption is $1,250,000 after the June 2024 Budget changes.

Crystallizing the LCGE: Owner-managers sometimes “crystallize” the exemption before the corporation grows beyond the $10M asset cap for SBC status, using a section 85 rollover or other reorganization to trigger a capital gain while the exemption is still available.

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) or terminal loss; proceeds greater than original cost = capital gain.
• Eligible capital property / goodwill: Post-2016 rules treat goodwill as Class 14.1 depreciable property; recapture and capital gains apply similarly.
• 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) 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: Business Structuring Tools — Section 85 and Section 86 Rollovers

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

Section 85 allows a transferor to defer tax on a disposition of eligible property to a taxable Canadian corporation in exchange for shares, provided both parties file a joint election. The transfer price (the elected amount) can be set anywhere between the property’s ACB 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.

GST/HST on section 85 transfers: GST/HST may apply to the transfer of eligible capital property. The joint election under ETA section 167 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 (the purchaser must intend to use the assets to make taxable supplies).

Section 5.2: Section 86 — Share-for-Share Exchanges and Reorganizations

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. This is frequently used to:

• Create preferred shares redeemable at a stated amount (a value freeze — see below).
• Restructure share classes in anticipation of admitting new shareholders.
• Separate 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.

Estate Freeze using Section 86: The classic estate freeze involves the owner-manager exchanging common shares for fixed-value preferred shares via s. 86, stopping the accrual of further growth in the owner-manager’s estate. New common shares are then issued to family members or a family trust at a nominal price, capturing all future growth in the next generation’s hands. This limits future estate tax exposure for the owner and shifts future capital gains to family members who can shelter them with their own LCGEs.

Chapter 6: Financial Reporting for Income Tax (ASPE)

Section 6.1: 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 (conceptually similar to IAS 12 but with differences in application). Tax assets and liabilities are recognized for temporary differences between the tax base and carrying amount of assets and liabilities.

Future income tax asset arises when the tax base of an asset exceeds its carrying amount (e.g., capital cost allowance is claimed faster than accounting depreciation) or when the carrying amount of a liability exceeds its tax base (e.g., warranty provisions deductible only when paid).

Future income tax liability arises when the carrying amount of an asset exceeds its tax base (e.g., the corporation has reversed timing on CCA).

Section 6.2: Key Differences Between Accounting and Tax Income

Reconciling accounting income to taxable income requires adding back non-deductible amounts and subtracting deductions allowed for tax only. The deferred tax balance on the balance sheet reflects the cumulative temporary differences multiplied by the expected future tax rate.

Chapter 7: Trusts and Estate Planning

Section 7.1: Trust Fundamentals

A trust is a legal relationship in which a trustee holds property for the benefit of a beneficiary. For tax purposes, a trust is an inter vivos (living) trust or a testamentary trust (arising on death). A trust is treated as an individual for Canadian income tax purposes and files its own return.

Family trust in private corporation planning: A family or discretionary trust is a common vehicle for holding shares of a private corporation. The trustees (often the owner-manager) hold shares for the benefit of family members. The trust can pay dividends to whichever beneficiary faces the lowest marginal tax rate in a given year, allowing income-splitting (subject to TOSI). Multiple beneficiaries can access separate LCGE amounts when QSBC shares are sold.

21-year deemed disposition rule: Trusts are subject to a deemed disposition at FMV of all trust property every 21 years (s. 104(4)). Careful planning is required to avoid large tax hits — assets may be distributed to beneficiaries before the 21-year anniversary, triggering rollover provisions under s. 107.

Section 7.2: Death of a Taxpayer

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: 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 (s. 70(6)).

RRSP/RRIF on death: The fair market value 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, or to a financially dependent child or grandchild in certain circumstances.

Estate planning integration: Effective estate planning combines testamentary trusts, life insurance (proceeds paid to the corporation, flowed through the CDA as a capital dividend to fund the estate tax), and careful ordering of asset disposals to minimize the total tax burden on death.

Chapter 8: Partnerships

Section 8.1: Tax Treatment of Partnerships

A partnership is not a taxpayer for Canadian income tax purposes — it is a conduit. Partnership income (or loss) is calculated at the partnership level and flows through to each partner in proportion to their interest. Each partner includes their share of partnership income (or loss) in their own return.

At-risk rules: A partner’s deductible share of partnership losses is limited to their at-risk amount — the ACB of the partnership interest adjusted for amounts the partner is not at risk to lose (e.g., guaranteed loans).

Limited partnerships: Limited partners benefit from liability protection but face stricter at-risk limitations. Their deductible losses cannot exceed their at-risk amount, and excess losses are suspended until the at-risk amount increases.

Section 8.2: Partnership vs. Corporation — Planning Considerations

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

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.

Chapter 9: The Problem-Solving Process for Tax — Case Analysis Framework

Section 9.1: 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 (qualitative analysis, quantitative comparison, or both).

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 (in a supporting Excel appendix), 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 that addresses the client’s overall objectives. 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 9.2: General Anti-Avoidance Rule (GAAR)

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.

GAAR analysis involves three elements: (1) Is there a tax benefit? (2) Is the transaction an avoidance transaction (no bona fide non-tax purpose)? (3) Is there misuse or abuse? 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.

In planning for owner-managers, GAAR risk arises in aggressive income-splitting structures, artificial PUC increases, and series of transactions designed to convert income into capital gains without economic substance.
