Canada Tax Deadlines
The dates that matter for the 2025 tax year, filed in 2026. Filing on time — even if you can't pay in full — usually keeps the late-filing penalty away.
Dates below are for the 2025 tax year (filed in 2026). When a deadline falls on a weekend or holiday, the CRA generally accepts a return as on time if it's received the next business day.
Individuals (T1)
Instalments, if you pay them, are due March 15, June 15, September 15 and December 15.
Self-employed (T1)
You get extra time to file, but any tax owing is still due April 30 — interest starts after that.
Corporations (T2)
Many Canadian-controlled private corporations that qualify for the small business deduction get 3 months to pay instead of 2.

Already missed one?
It happens, and it's fixable. Filing late can bring a penalty plus interest, but the CRA can reduce or waive some of it depending on your situation — and filing now stops it from growing.
