What’s the penalty for missing the deadline to file your personal income tax return?

What’s the deadline for filing taxes in 2017?

For self-employed people and their spouses or common-law partners the deadline for filing their 2016 personal income tax return is June 15, 2016. If they owe money however, interest begins to accrue starting on May 1, 2017.

For everyone else the deadline is April 30, 2017.

If a person files their return late, and owes money, the late filing penalty is 10% of the amount they owe and interest accrues from May 1, 2017 to the date the amount is finally paid.
