For most individuals in Canada, the deadline to file a personal income tax return is April 30 each year. If the date falls on a weekend or holiday, the deadline moves to the next business day.
June 15 self-employed filing
For people who are self-employed and wondering when does tax season start in Canada, they are required to file their taxes by June 15 of each year. However, if they owe taxes, they must still pay the tax amount by April 30, or they will incur interest on the amount owed.
Payment due dates
Payments owed to the CRA should be made on April 30, regardless of the date of your filing deadline. If you file past the April 30 deadline, you will begin to incur interest from the CRA, accruing until you pay your outstanding balance in full.
