Most deadlines for the 2026 tax year fall between December 2026 and June 2027. Missing a payment deadline costs interest even when you file on time, so the payment dates matter most.
Dates for the 2026 tax year
| Date | What's due |
|---|---|
| December 15, 2026 | Final 2026 quarterly instalment, if you pay by instalments |
| December 31, 2026 | Last day for 2026 charitable donations and FHSA contributions |
| March 1, 2027 | RRSP contribution deadline for the 2026 tax year |
| April 30, 2027 | Filing and payment deadline for most individuals |
| April 30, 2027 | Payment deadline for the self-employed, even though they file later |
| June 15, 2027 | Filing deadline if you or your spouse or common-law partner are self-employed |
When a deadline falls on a weekend or public holiday, CRA treats a return or payment as on time if it's received on the next business day.
The self-employed: file in June, pay in April
Self-employed people and their spouses have until June 15 to file, but any balance owing is still due April 30. Interest starts on May 1 on anything unpaid. If you expect to owe, estimate and pay by April 30.
Instalments in 2027
If CRA sends you instalment reminders, the 2027 instalments are due March 15, June 15, September 15 and December 15, 2027. Instalments are generally required when your net tax owing is more than $3,000 in the current year and in either of the two previous years.
Proposed changes
Budget 2026, tabled November 5, 2026, proposes a single May 15 filing and payment date for individuals, including the self-employed, starting with the 2027 tax year. It also proposes raising the instalment threshold to $7,500 from 2028. These are proposals until passed and don't change the dates above for your 2026 return.
