Missing the tax filing deadline in Canada has real consequences — both financial penalties and lost benefits. Here is everything you need to know about when to file, what happens if you are late, and why filing early is almost always the right move.
For most individuals in Canada, the deadline to file your income tax return is April 30 of the year following the tax year. For example, your 2024 tax return must be filed by April 30, 2025. If April 30 falls on a weekend or holiday, the deadline moves to the next business day.
If you or your spouse or common-law partner are self-employed, the deadline to file your tax return is June 15. However — and this is critical — any taxes you owe must still be paid by April 30. Filing by June 15 but owing taxes means interest starts accumulating from May 1, even though you filed on time.
If you owe taxes and file late, the CRA charges a late-filing penalty of 5 percent of the balance owed, plus 1 percent for each full month your return is late, up to a maximum of 12 months. If you have filed late before, the penalty increases. Interest also compounds daily on any unpaid amount from May 1 onward.
If you cannot pay the full amount by April 30, file your return on time anyway to avoid the late-filing penalty. Then contact the CRA at 1-888-863-8657 to arrange a payment plan. The CRA works with taxpayers who reach out proactively. The worst thing to do is not file at all.
Many newcomers assume that if they had no income, they do not need to file. This is incorrect — and costly. Filing your return, even with zero income, activates your GST/HST credit, Climate Action Incentive Payment, Canada Child Benefit if you have children, and provincial benefits like the Ontario Trillium Benefit. Every year you do not file is a year you decline those payments.
