Shareholder Benefits Under Section 15: The Double Tax
What happens when a corporation pays a shareholder's personal costs or lets them use company property, why the corporation gets no deduction, and the one-year loan rule.
Reviewed by the Fairlight Accounting cross-border tax team — U.S. & Canadian Tax Desks
Subsection 15(1) of the Income Tax Act taxes a shareholder on any benefit the corporation confers — a personal expense paid by the company, use of corporate property, or an asset transferred below value. The corporation gets no deduction, so the same dollars are taxed twice: once in the corporation and again in the shareholder's hands.

What counts as a benefit?
| Situation | Treatment |
|---|---|
| Company pays the owner's personal travel, home renovations, or family expenses | Benefit at cost, no corporate deduction |
| Owner uses a corporate cottage, boat, or condo | Benefit usually at fair market rent; where rent would not give a reasonable return on the property — a luxury home or yacht — a normal rate of return on the greater of cost or fair market value, plus operating costs (Youngman v. The Queen, Federal Court of Appeal, 1990) |
| Corporate automobile available for personal use | Benefit measured by the standby charge and operating cost rules (subsection 15(5)) |
| Asset sold to the shareholder below market | Benefit equal to the shortfall |
| Loan to a shareholder not repaid within one year after the end of the corporation's taxation year in which it was made | Loan included in income under subsection 15(2) |
| Low-interest shareholder loan | Imputed interest benefit at the prescribed rate (3 percent for October–December 2026) under subsection 80.4(2) |
Why is it worse than a dividend or salary?
A dividend is paid from after-tax corporate income but carries the dividend tax credit, and salary is deductible to the corporation. A section 15 benefit is neither: it is taxed to the shareholder at full rates, with no credit, and the corporation cannot deduct it. A $20,000 personal expense can cost more than $20,000 in combined tax and penalties once gross negligence penalties are added.
How does the shareholder loan rule work?
A loan from a corporation to a shareholder (or a connected person) is included in the shareholder's income unless it is repaid within one year after the end of the corporation's taxation year in which it was made — and repayment cannot be part of a series of loans and repayments. Exceptions exist for loans in the ordinary course of a lending business and for certain employee loans. Interest-free or low-interest loans that are repaid in time still generate an imputed interest benefit.
How does the CRA find them?
Reviewing the shareholder loan account, corporate credit card statements, and expense ledgers for personal items; comparing corporate assets to their use; and net worth analysis where lifestyle exceeds reported income. Owner-managed corporations are a standing audit focus.
How do you fix an exposure?
Declare the amount as a bonus or dividend before year-end so it is taxed once with the proper treatment; repay loans within the deadline; charge yourself fair rent or a standby charge for corporate property; keep personal spending off corporate accounts. Reclassification after an audit begins is usually too late.
What if the shareholder is a U.S. person?
A U.S. owner of a Canadian corporation reports the benefit on the Canadian side and faces a parallel U.S. concept — a constructive dividend — on the U.S. return, with foreign tax credit coordination that often leaves some double tax in place.
Frequently asked questions
Can I reverse the benefit by repaying the corporation later?
Repaying a personal expense before year-end, with proper bookkeeping, generally avoids a benefit; repaying after a reassessment does not undo it.
Are shareholder-employees treated differently?
A benefit received in the capacity of employee is taxed as employment income and is deductible to the corporation; the CRA decides which capacity applies based on what other employees receive.
Does a loan to my spouse count?
Yes. Loans to persons connected with a shareholder are covered.
Is the prescribed interest rate the same as the CRA's interest on overdue tax?
No. For October 1 to December 31, 2026, the prescribed rate for loan benefits is 3 percent, while overdue tax bears 7 percent; both are reset quarterly.

The CRA explains: “Subsection 15(1) generally requires a shareholder of a corporation to include in income the value of any benefit conferred on the shareholder by that corporation. An example of such a situation would be where a corporation pays a shareholder’s personal expenses and there is no agreement between the shareholder and the corporation for reimbursement.” — Canada Revenue Agency, Income Tax Folio S3-F1-C1, Shareholder Loans and Debts, https://www.canada.ca/en/revenue-agency/services/tax/technical-information/income-tax/income-tax-folios-index/series-3-property-investments-savings-plans/folio-1-shares-shareholders-security-transactions/income-tax-folio-s3-f1-c1-shareholder-loans-debts.html
The Income Tax Act provides: “If, at any time, a benefit is conferred by a corporation on a shareholder of the corporation, on a member of a partnership that is a shareholder of the corporation or on a contemplated shareholder of the corporation, then the amount or value of the benefit is to be included in computing the income of the shareholder” — Justice Laws Website (Government of Canada), Income Tax Act, section 15, https://laws-lois.justice.gc.ca/eng/acts/i-3.3/section-15.html
