What is a shareholder loan and what happens if I do not repay it?

What counts as a shareholder loan

Any amount a corporation advances to a shareholder, or to someone connected to a shareholder, that is not immediately repaid or otherwise accounted for as salary, dividends, or reimbursement of a genuine business expense, is treated as a shareholder loan. This often happens informally: an owner-manager takes cash out of the corporate account to cover a personal expense, intending to sort it out later through year-end bookkeeping, without ever formally documenting a loan or repayment schedule. The CRA does not require a loan to be labelled as such on paper for section 15 to apply; it looks at the substance of the withdrawal.

The one-year repayment window

The key deadline is not one year from when the loan was made, it is one year after the end of the corporation’s fiscal year in which the loan occurred. A loan taken out early in a fiscal year effectively has close to two years to be repaid before triggering the rule, while a loan taken in the last month of the fiscal year has barely more than one year. If the loan remains outstanding past that deadline, the full original amount, not just the unpaid portion, is included in the shareholder’s income for the year the loan was originally received, which can mean amending a prior year’s personal return once the deadline passes.

Repaying and re-borrowing does not reset the clock

A pattern of repaying a shareholder loan right before the deadline and then re-borrowing a similar amount shortly after is specifically targeted by a series of loans and repayments rule. If the CRA concludes that a repayment was made only to avoid the income inclusion, with the clear intention of borrowing again, the repayment is disregarded for purposes of the one-year test, and the original loan is still treated as unrepaid. This rule exists precisely because the one-year deadline would otherwise be trivial to work around with a same-day repay-and-reborrow.

Even a repaid loan can trigger a taxable benefit

Separately from the income inclusion for an unrepaid loan, a shareholder who receives an interest-free or low-interest loan from the corporation is generally taxed on a deemed interest benefit, calculated using the CRA’s quarterly prescribed interest rate, for the period the loan is outstanding, even if it is repaid well within the one-year window. This benefit can sometimes be offset if the shareholder actually pays interest to the corporation at or above the prescribed rate within the required time, but a genuinely interest-free loan, even one repaid promptly, is not necessarily tax-free.

Multiple shareholders complicate the picture further

In a corporation with more than one shareholder, each shareholder's loan balance and repayment timeline is tracked separately, and one shareholder repaying their own balance does nothing for another shareholder's outstanding amount. This matters in family-owned corporations where a parent and adult children are all shareholders and draw funds informally at different times through the year; each person's withdrawals need their own running balance and their own one-year deadline tracked against the fiscal year in which they occurred, rather than being netted together as one shared number.

The narrow exceptions

A few specific situations are excluded from the full-inclusion rule, including certain loans to an employee-shareholder to buy a home, to buy shares of the corporation, or to buy a vehicle used for employment duties, provided bona fide repayment arrangements exist and the loan was made because of employment rather than because of shareholdings. These exceptions are narrower than they sound and depend heavily on the specific facts, so they should not be assumed to apply without checking the details against the actual arrangement.

Cleaning up a shareholder loan before it becomes a problem

The practical fix for a loan approaching its deadline is usually to convert it into something that is properly taxed rather than let the deadline pass: declaring a bonus or salary to the shareholder that is then used to offset the loan balance, or declaring a dividend for the same purpose, following the same tradeoffs covered in salary or dividends from your corporation. Both routes create real personal tax, since salary and dividends are taxable regardless, but they are generally more predictable and better understood than the section 15(2) full-inclusion consequence, which can also complicate a prior year’s return once triggered. This is exactly the kind of item worth reviewing before a corporation’s year-end closes, not after.

Why bookkeeping quality decides whether this rule even gets noticed

A shareholder loan only gets managed properly if it is visible in the books in the first place. In a corporation where personal expenses are occasionally paid from the business account and simply coded to a miscellaneous or suspense account, the running balance owed back to the corporation can drift for months without anyone actually tracking the one-year deadline against it. Clean, current bookkeeping that posts these withdrawals to a proper shareholder loan account as they happen is what makes the deadline visible early enough to act on, rather than surfacing it for the first time when the corporate return is finally being prepared, often close to or past the very deadline the rule is built around.

How we handle this

We track shareholder loan balances and their one-year deadlines through the year rather than discovering them at tax time, and we plan the salary-or-dividend cleanup before a deadline passes rather than after. This is part of our bookkeeping and corporate tax work for owner-managed corporations.
