Accruing a bonus to a key employee or owner-manager at year-end is one of the most common tax-planning moves for an Ontario corporation — it lets the corporation deduct the expense in the year it's earned, even if the cash hasn't actually gone out the door yet. But that deduction comes with a catch: the Income Tax Act's salary deferral arrangement rules require the bonus to actually be paid within a specific window after year-end, or the whole plan can unravel.
Here's why that rule exists, what triggers it, and how to structure a bonus accrual so it holds up.
The Bonus Accrual Strategy, and Why the CRA Watches It
A corporation on the accrual method of accounting can deduct a bonus in the year it's declared and owed to an employee, even if it's actually paid out early in the following year. This is a completely normal and accepted timing tool: it lets the corporation's expense match the year the work was done and the obligation was created, rather than the year the cheque happens to clear.
The CRA's concern isn't the accrual itself. It's what happens if the short gap between accrual and payment starts to look less like normal payroll timing and more like an indefinite, tax-motivated deferral of income the employee has already effectively earned.
What a Salary Deferral Arrangement Actually Is
A salary deferral arrangement, or SDA, is the Income Tax Act's label for an arrangement where compensation is earned in one year but structured to be received, and taxed, meaningfully later, in a way that primarily serves to defer the employee's personal tax rather than reflecting a genuine business reason for the delay. If an accrued bonus is left unpaid for too long after the corporation's year-end, the CRA can treat it as falling into this category rather than as an ordinary short-term accrual.
The Payment Window: Why Timing Isn't Optional
The Income Tax Act's salary deferral arrangement rules carve out a bonus arrangement only if the accrued bonus is actually paid within a set window — measured in years, not months — after the end of the year in which the services were earned. A separate, much shorter rule (measured in days after the corporation's year-end) governs whether the corporation can deduct the bonus in the year it was accrued rather than the year it is actually paid. Both windows are worth confirming precisely with your accountant before you rely on them, since missing either one can change the tax result significantly.
What Happens If the Window Is Missed
If an accrued bonus isn't paid within the required window, the CRA can recharacterize the arrangement as a salary deferral arrangement. The practical effect is that the employee can be required to include the deferred amount in income for tax purposes on essentially the same schedule as if it had been paid on time, meaning they may owe tax on money they haven't actually received yet, while the corporation's deduction timing and treatment can also be thrown into question. Neither side of that outcome is one you want to discover after the fact.
Common Situations That Trigger the Rule
- A corporation accrues a bonus at year-end intending to pay it "when cash flow allows," and that turns into a much longer delay than planned
- A bonus is declared to an owner-manager but effectively left as a loan or credit on the books rather than actually paid out
- A corporation restructures compensation to intentionally push an employee's tax liability into a later year without a genuine business reason for the delay
How to Structure a Year-End Bonus Correctly
- Have the board, or the sole director for a small corporation, formally approve the bonus with a resolution specifying the amount and the recipient before the fiscal year-end.
- Record the accrued liability properly in the corporation's year-end financial statements.
- Diarize the payment deadline based on the corporation's specific year-end, and actually pay the bonus, by cheque, direct deposit, or another real transfer of funds, within the required window.
- Confirm the correct source deductions are applied when the bonus is actually paid.
- Keep the resolution, the accrual entry, and proof of payment together in the corporate records in case the CRA asks about the timing later.
Frequently asked questions
Can I just accrue a bonus every year and never actually pay a large chunk of it?
No. That pattern is precisely what the salary deferral arrangement rules are designed to catch. A genuine year-end accrual that's actually paid within the required window is fine; a recurring, growing, unpaid balance is a red flag.
Does the salary deferral arrangement rule apply to dividends?
No. Dividends aren't compensation for services and aren't accrued the same way a bonus is. The SDA rules are specifically about deferred employment income, not dividend distributions.
What if the corporation genuinely doesn't have the cash to pay the bonus on time?
If cash flow is the real constraint, it may be worth accruing a smaller bonus that the corporation can actually pay within the required window, rather than accruing the full intended amount and risking the timing rule. Talk to your accountant about the trade-offs before year-end.
Does this rule apply to bonuses paid to arm's-length employees too, or just owners?
The rule applies to accrued compensation generally, not just amounts paid to owner-managers, but it tends to come up most often in owner-manager situations, where the same person is deciding when to declare the bonus and when to actually pay it.
