When are taxes due for self-employed Canadians?

Self-employed Canadians (and their spouses) have until June 15 to file, but any balance owing is due April 30 — interest starts after that date. When a deadline falls on a weekend or CRA-recognized holiday, the next business day counts as on time.

When are CRA tax instalments due in 2026?

Quarterly instalments are due March 15 (March 16 in 2026, since the 15th is a Sunday), June 15, September 15 and December 15. Farmers and fishers instead pay one annual instalment on December 31.

Greyed rows have passed. The RRSP deadline for the 2026 tax year is added the moment the CRA publishes it (typically the first business day of March 2027 — we don't print dates the CRA hasn't confirmed).

The rules behind the dates

Weekend rule: when a due date falls on a Saturday, Sunday or CRA-recognized public holiday, your payment or return is on time if the CRA receives it the next business day. The table above already applies this rule and says so wherever a date moved.
April 30 vs June 15: self-employed Canadians get until June 15 to file, but any balance owing is due April 30 — interest starts the day after. Estimate your balance before April.
Quarterly instalments: required when your net tax owing is over the CRA threshold this year and in one of the two prior years. Check whether you have to pay, and compare the three CRA payment options.
GST/HST: monthly and quarterly filers file and pay one month after each reporting period; annual filers with a December 31 year-end pay April 30 and file June 15. Registration becomes mandatory once you cross the small-supplier threshold — the categorizer flags GST/HST treatment per expense.
Farmers and fishers: one annual instalment on December 31 instead of four quarterly payments.
