Bonus accrual (s. 78(4))

A bonus accrual is a bonus a corporation records as an expense for a year before paying it. Under section 78(4) of the Income Tax Act, salary, wages or other remuneration for an office or employment, with listed exclusions, that is unpaid on the day 180 days after the year-end is deemed not incurred that year, and is treated as an expense in the year it is paid.

A seller’s corporation meets this rule when it deducts a year-end bonus it has accrued but not yet paid. Subsection 78(4) covers an expense that is a superannuation or pension benefit, a retiring allowance, salary, wages or other remuneration in respect of an office or employment.

How the 180-day rule works

The Act excludes reasonable vacation or holiday pay and a deferred amount under a salary deferral arrangement. The CRA’s archived bulletin IT-109R2 says a payment made on the 180th day is treated as in time, and that an amount paid after the deadline is deductible in the year it is paid. It also says that where subsection 78(1) and subsection 78(4) both apply, as with unpaid salary owed to an employee not at arm’s length, subsection 78(4) governs.

What to ask

  • Which bonuses or other remuneration were accrued at the last year-end and are still unpaid
  • Whether payment was or will be made within 180 days of that year-end
  • Who is responsible for paying them under the purchase agreement
