Tax Filing and Compliance — Canada

Anyone who owes income tax for the year must file a return. This includes income from employment, self-employment, investments, or other sources not fully covered by tax withholding.

If CRA sends you a demand to file, you must comply. Failure to file when demanded can result in penalties and prosecution.

Must file to receive GST/HST credit, Canada Child Benefit, Canada Workers Benefit, and provincial benefits. Even with no income, filing ensures benefit eligibility.

Anyone with self-employment income must file to report income and pay CPP contributions. Extended filing deadline (June 15) but payment deadline remains April 30.

Earliest date to electronically file your return. Early filers typically receive refunds within 8 business days. CRA recommends electronic filing for fastest processing.

Last day to contribute to RRSP for the 2025 tax year deduction. March 2 because March 1 falls on Sunday. Contributions after this date count toward 2026.
