Shareholder loan rules in Canada are one of those things most incorporated owners only learn about the hard way. You pull money out of your company for a personal expense, it gets recorded as a "due to shareholder" receivable, and everyone moves on. Then the CRA reassesses you, adds the full loan to your personal income for the year, and the tax bill lands like a piano. Here is how the rule actually works, the exceptions that save you, and the traps that catch smart people every single year.
The basic rule: borrow from your company and the CRA may tax the full amount
Subsection 15(2) of the Income Tax Act says that if your corporation lends money to you as a shareholder, the loan amount gets included in your personal income for the year the loan was made. The rule also catches loans to people connected with you, so routing it through a spouse or a family member does not dodge it.
The logic is simple. Without this rule, every owner would "borrow" their salary instead of declaring it and skip the tax. The CRA treats an unpaid shareholder loan as disguised pay unless you can point to a specific exception. That is the starting position, and the burden is on you.
Shareholder loan rules in Canada: the one-year repayment exception
The exception most owners rely on is the one-year repayment rule. Your loan escapes the income inclusion if you repay it within one year after the end of your corporation’s taxation year in which the loan was made.
Timing matters enormously, so do the actual math. Say your corporation has a December 31 year-end. You borrow $40,000 on March 10, 2026. You have until December 31, 2027 to repay it, which is nearly two years of breathing room. But if you borrow that same $40,000 on December 20, 2026, your deadline is still December 31, 2027, which is barely a year. A loan taken early in the year buys you far more time than one taken in December. A handy rule of thumb is "roughly two year-ends," but never rely on the thumb when the calendar decides the tax.
There are narrower exceptions too, such as loans made in the ordinary course of a money-lending business, but for a typical operating company the one-year rule is the one that matters.
The trap: repay it, then borrow it right back
Here is where owners get creative, and where the CRA is waiting. The one-year exception does not apply if the repayment is part of a series of loans and repayments. Repay the loan on December 30 and borrow a similar amount on January 5, and the CRA will treat the whole thing as one continuous loan. The income inclusion applies anyway.
The CRA looks at substance, not paperwork. If the pattern shows you never intended to stay repaid, the exception fails. A genuine repayment means the money stays repaid, with a documented repayment schedule you actually follow. Do not play timing games with this rule. It is the single most common way shareholder loans blow up in an audit.
Even a safe loan can cost you: the interest benefit under section 80.4
Suppose your loan is safely within the one-year window. You are still not done. An interest-free or low-interest loan from your corporation triggers a taxable benefit under section 80.4, calculated as the CRA prescribed rate minus whatever interest you actually paid.
The rate used to calculate taxable benefits on employee and shareholder loans is 3% for both the third and fourth quarters of 2026. So a $50,000 interest-free loan outstanding for a full year adds a $1,500 taxable benefit to your income. Not catastrophic, but it is real money, it compounds across years the loan stays open, and owners routinely forget to report it.
The fix is straightforward: charge yourself at least the prescribed rate, put it in writing, and actually pay the interest. A dated promissory note with an interest rate and repayment terms turns a suspicious withdrawal into a defensible loan.
What clean shareholder-loan hygiene looks like
Most shareholder-loan problems are bookkeeping problems wearing a tax costume. Keep it clean:
- Record every advance in a separate shareholder loan account, dated, with a running balance. Never bury personal draws in generic expense accounts.
- Put the loan in writing: a simple promissory note stating the amount, the interest rate, and the repayment schedule.
- Make real repayments on schedule and reconcile the account monthly. Your bookkeeper should be flagging the balance every quarter, not discovering it at year-end.
- Pass a director or shareholder resolution approving the loan. It takes five minutes and it matters in an audit.
If your "due to shareholder" balance has been growing for months with no repayments and no paperwork, that is not a loan. That is a warning light.
Sometimes a loan is the wrong tool entirely
Be honest about what the money really is. If you need the funds permanently, pay them to yourself properly: salary with source deductions remitted, or dividends declared and reported on a T5. A "loan" you never intended to repay is just undeclared income with extra steps, and the CRA knows the difference.
Owners often ask whether salary or dividends work out better in a given year. The honest answer is that it depends on your income level, your RRSP room, and your cash needs, which is exactly the kind of thing worth modelling before you move the money rather than after. Our guide to when to incorporate in Canada walks through the bigger picture of running income through a corporation.
And if the loan already went sideways and got included in your income, all is not lost. Paragraph 20(1)(j) of the Income Tax Act lets you claim a deduction in the year you repay it. You cannot carry the deduction back to the original year, but repayment does eventually unwind the damage.
The bottom line
Shareholder loans are perfectly legal, but they run on paperwork and deadlines. Miss the one-year repayment window, or repay-and-reborrow your way around it, and the full amount becomes personal income. Keep the loan interest-free without reporting the benefit, and section 80.4 adds its own tax. None of this is complicated. It just has to be done on time, in writing, and reconciled every month.
For the technical source behind these rules, the CRA’s audit manual chapter on benefits from loans and debts sets out how 15(2), 20(1)(j), and 80.4 fit together.
