Personal income tax return filing deadline for most Canadians. This is also the deadline to pay any balance owing. Filing late when you owe results in a 5% penalty plus 1% per month interest up to 12 months.
Filing deadline for self-employed individuals and their spouses. However, any balance owing is still due April 30. Filing on June 15 with a balance owing will result in interest charges from May 1 onward.
First offence: 5% of the balance owing + 1% per month up to 12 months. Repeat offence (if charged in any of the previous 3 years): 10% of the balance owing + 2% per month up to 20 months.
