I borrowed from my company. When does it become taxable?

The clock: one year after the corporation's year-end, not one year after the loan

The deadline is measured from the end of the corporation's taxation year in which the loan was made, which means identical loans can have very different runways. Borrow the day after your year-end and you have almost two full years to repay; borrow the week before year-end and you have barely one. Owners consistently misremember this as one year from the borrowing date, and the difference is where trouble starts.

Miss the deadline and the full principal is included in your income for the year the loan was made, not the year the deadline passed. That backdating is what makes the miss expensive: it can mean reassessing a personal return you filed two years ago, with arrears interest running from that year's balance-due date. The shareholder loan account is also rarely one loan; it is a running tally of draws, personal expenses paid on the company card and transfers, so the clock question is really asked balance by balance, year by year.

One scope note: the rule catches loans to shareholders, to people connected with a shareholder, including family members, and loans routed through related entities. Having your spouse or your other company do the borrowing does not change the answer.

It is worth being honest about why the rule exists, because the logic predicts how firmly it is applied. An Ontario CCPC pays 12.2 per cent on its first 500,000 dollars of active business income, while the same profit taken as salary or dividends bears personal tax on top. If owners could simply borrow the corporate surplus indefinitely, nobody would ever pay the personal layer; the money would sit invested in the corporation, earning passive income at low-taxed capital, while the owner spent it personally. The one-year rule is the fence around that deferral, which is why the exceptions are narrow and the series rule has teeth.

Inside the window you are still taxed on something: the interest benefit

Even a loan you repay on time produces a taxable interest benefit for every day the money was out, calculated at CRA's prescribed rate, which is set quarterly. The benefit is the prescribed-rate interest for the period, minus any interest you actually paid for that period, and interest for a calendar year only counts if it is paid within 30 days after the year ends. Pay interest at the prescribed rate on schedule and the benefit is nil; pay nothing and a taxable benefit lands on your return for each year the balance is outstanding.

The benefit is usually small compared to the principal inclusion, which is why it gets ignored, and ignoring it is a mistake in the other direction: an unreported interest benefit on a large balance across several years is exactly the kind of easy pickup a CRA review starts with. There is a narrow exception where the loan was received in your capacity as an employee rather than as a shareholder and the rate was set on commercial terms at the time; for an owner-manager who controls the company, capacity is hard to argue, so we treat the benefit as a cost of any balance left outstanding.

The trap: repaying and reborrowing counts as never repaying

Repaying the loan just before the deadline and drawing the money out again shortly after does not work, because repayments that are part of a series of loans and repayments are ignored. The pattern the rule targets is the revolving personal balance: clear the account in the last month of the window, reborrow in the next quarter, repeat. On review, CRA looks through the choreography, treats the original loan as never repaid, and the income inclusion lands in the original year with interest.

What does count as genuine repayment: a declared bonus or dividend applied against the loan balance, because the money has borne tax on its way to you; cash you repay and do not draw back out; or a documented set-off against amounts the corporation genuinely owed you. The dividing line is whether the source of repayment stands on its own or is just the same corporate money making a round trip. A well-run file makes this obvious: the resolution declaring the dividend, the journal entry applying it to the loan, the account left at zero and staying there.

This is also why we tell owners to stop thinking of the loan account as a payment method. It is a bridge to the next properly taxed payment, nothing more. If you find yourself borrowing every year and clearing it every year with a scramble, the real problem is that your salary and dividend plan is set too low for how you actually live, and the fix is the plan, not the bridge; the trade-offs are laid out in salary versus dividends for Canadian business owners.

The exceptions that genuinely keep a loan tax-free

A few categories of loan survive past the one-year window without an income inclusion, and they are narrower than owners hope. The main ones:

• Repaid in time, outside any series: the ordinary case, covered above, still the cleanest answer.
• Lending is the corporation's business: loans made in the ordinary course of a genuine money-lending business, with bona fide repayment arrangements, are outside the rule. This describes actual lenders, not an operating company making one loan to its owner.
• Employee loans for specific purposes: loans to buy a home, previously unissued shares of the company, or a car used in employment duties can stay out of income if bona fide repayment arrangements are made within a reasonable time, and, critically, if the loan came to you because of your employment rather than your shareholding. For a shareholder holding 10 per cent or more, that capacity test is the hard part: you generally need to show comparable employees could get the same deal.

In practice, for a typical owner-manager who owns most or all of the company, we plan as if no exception applies. The employee-purpose exceptions are real but fragile on the facts, they still generate the interest benefit each year, and losing the argument years later means the full inclusion plus arrears interest. Where a house purchase or similar need is driving the borrowing, we would rather design the withdrawal properly than defend a capacity argument.

If the deadline has passed, or is about to: the repair options

With the deadline approaching, the goal is to convert the balance into properly taxed income before the window closes, and the menu is short. Declare a bonus and apply it net of withholdings against the loan: deductible to the corporation, T4 income to you. Declare a dividend on your shares and set it off: simpler, no source deductions, taxed at dividend rates, and it can release refundable tax the corporation is holding. Repay with personal funds if the cash exists. Or, where the corporation has a capital dividend account from past capital gains or life insurance proceeds, elect and pay a capital dividend against the balance, which clears it with no personal tax at all; the timing rules are strict and the balance must be verified first. Which mix is cheapest depends on your bracket, the corporation's tax pools and the year, which is exactly the annual sequencing question we work through in should I pay myself salary or dividends.

Refundable tax is the pool owners forget in this decision. A corporation that has been earning investment income on its surplus has usually paid refundable tax that only comes back when it pays taxable dividends. Clearing a shareholder loan with a dividend can therefore do double work: the dividend retires the loan, and the corporation receives a refund of part of the tax it already paid. In the right year, the net cost of that clearing dividend is far lower than the rate table suggests, which is why we look at the corporation's tax pools before choosing between bonus and dividend rather than defaulting to either.

If the deadline has already passed, the inclusion is the starting point, not the end. The principal goes into income for the year the loan was made, which may mean an adjustment to a filed return, and there is a matching relief: when you later repay the loan, and the repayment is not part of a series, you deduct the repaid amount from income in the year of repayment. The tax is a timing cost rather than a permanent one, but the arrears interest is real money, and a file corrected voluntarily reads very differently on review than one corrected after a query. This is clean-up work we handle regularly, quietly and in the right order.

What changes the answer, and how to keep the account boring

Five facts determine how dangerous a shareholder loan balance actually is:

• The corporation's year-end relative to the draw date: it sets the real deadline, anywhere from about 12 to 24 months.
• The pattern in the account: a single documented draw reads as a loan; a revolving balance cleared and redrawn each year reads as a series.
• Whether interest is being paid: paid at the prescribed rate on time, the benefit disappears; unpaid, it accrues on your return every year.
• What the corporation has available to clear it: bonus capacity, dividend room, refundable tax to recover, or a capital dividend account each change the cheapest exit.
• Your personal bracket in the clearing year: the same dividend costs very different tax in a low-income year than a top-bracket year.

Remember also that the account runs both ways. Money you have lent the corporation, startup capital, an unpaid bonus, expenses you covered personally, sits as a credit balance, and drawing against it is simply the company repaying its debt to you: no deadline, no benefit, no tax. Many so-called shareholder loan problems dissolve once the account is properly reconciled and the credit history is documented, because the draws were repayments all along. The reverse is also true: personal expenses run through the company card without bookkeeping discipline can quietly build a debit balance nobody planned, which is how owners end up surprised in the first place.

Keeping it boring is a bookkeeping habit plus a calendar: every draw recorded when it happens, the account reviewed at year-end while there is still time to act, and the balance cleared by plan rather than by panic. That review is standing work for a corporate tax planning CPA in Ontario, and inside our Tax Planning & Advisory engagements the loan account is checked at every year-end alongside owner pay.
