Federal corporate tax balance-due day
Two months after year-end; three months where the balance-due-day conditions are met.
Who it applies to
Every corporation with a tax balance owing. The three-month deadline requires three cumulative conditions: a deduction claimed under section 125 in the current or preceding year, CCPC status throughout the year, and prior-year taxable income not exceeding the business limit.
Important qualification
The three-month balance test is NOT the quarterly instalment test — see “Federal corporate instalments”. A corporation can meet one without the other.

If you miss the date
Interest compounds daily on the unpaid balance from the due date. The balance is due BEFORE the return: paying on time without filing does not avoid the late-filing penalty, and filing on time without paying does not avoid interest.
File with Canada Revenue AgencyFrequently asked questions
- Does paying on time without filing avoid the penalty?
- No. These are two distinct failures: the late-filing penalty targets the late return, interest targets the late payment. Avoiding one does not avoid the other.
- Is the three-month test the same as the quarterly instalment test?
- No, and the confusion is expensive. Quarterly instalments fall under ss. 157(1.1) and 157(1.2); the three-month balance falls under the definition of “balance-due day” in s. 248(1). A corporation can meet one without the other.
