Canada tax day for the 2025 return was April 30, 2026. That was the last day for most people to file and to pay any tax owing. For the 2026 return, filed in 2027, tax day is April 30, 2027 (June 15, 2027 for the self-employed filing date).
What were the tax day dates for 2025?
April 30, 2026 was the date that mattered for nearly everyone. If you or your spouse ran a business in 2025, you had until June 15, 2026 to file, but the CRA still wanted your payment on April 30. The filing window opened on February 23, 2026, when NETFILE started taking returns.
| Who | File by | Pay by |
|---|---|---|
| Most individuals | April 30, 2026 | April 30, 2026 |
| Self-employed, or spouse self-employed | June 15, 2026 | April 30, 2026 |
| Self-employed with tax shelter investments | April 30, 2026 | April 30, 2026 |
Those are the 2025 dates on the CRA’s due dates page, and they matter now mostly as a guide to what the next round is likely to look like, since the 2026 return dates follow the same pattern. If a date falls on a weekend or a holiday, the CRA counts your payment as on time on the first business day after it.
When is canada tax day for the 2026 return?
For most people it is April 30, 2027, and that day is a Friday. June 15, 2027 falls on a Tuesday for business owners, though any balance is still due April 30. Check the CRA’s page before you plan around either date.
Instalments have their own rhythm. If you’re on them, the payments fall on March 15, June 15, September 15 and December 15, and the next one is December 15. Our tax instalments calculator puts $9,000 of expected tax into four payments of $2,250.00.
What does missing tax day cost?
Only a balance owing triggers the penalty. The CRA charges 5% of it, plus 1% for each full month you’re late, up to 12 months. If you were penalized in one of the last three years, the repeat rate is 10% plus 2% a month, up to 20 months. Interest compounds daily from the day after the due date.
Here’s a real-sized case. Say you have $80,000 of employment income in Ontario and $12,000 of tax withheld. The tax refund calculator shows $2,127.85 owing. File two full months late and the penalty is 7%, which is $148.95, before interest. File on time but pay late, and interest still runs from the day after the due date. We didn’t confirm any other charge for that case, so read your notice.
Don’t sit on it. The penalty keeps growing every month you wait, so it’s rarely worth the delay. File anyway, since a missing return can also hold up benefit payments such as the GST/HST credit.
What if you can’t pay everything on tax day?
File on time regardless. Late filing is what triggers the penalty, and the penalty is a percentage of what you owe, so the return itself shouldn’t wait for the money. Then pay what you can and ask the CRA about options for the rest through My Account or by phone. We haven’t checked the details of any payment arrangement, so get the terms from the CRA directly.
How do you get ready before tax day?
Start with the slips. Gather your T4 and any bank or investment slips, and check your CRA account for copies before you file. Then estimate the bill so the payment doesn’t come as a surprise, and set money aside if you’re self-employed, because nobody withholds tax on your behalf during the year.
Take Taylor in Winnipeg, a freelance photographer. Every month Taylor tucks a slice of income into a separate savings account, so when tax time comes the money is already sitting there. It’s an old trick, and it works.
Mistakes around tax day
Thinking June 15 moves the payment. It doesn’t, and that catches self-employed people every year.
Waiting for a slip that never arrives. File with what you have, then amend.
Counting on a weekend date to move. The rule helps if it does, but pay early.
Guessing your balance. Run the numbers first: the income tax calculator gives an estimate in a minute, and the self-employed tax calculator adds CPP for business owners (but not EI or expenses).
Where do these dates come from?
The 2025 filing and payment dates, the weekend rule and the penalty rates come from Canada Revenue Agency pages, read in September 2026. We worked out the weekdays ourselves, so confirm the dates on the CRA page. This is an independent guide, separate from any government body.
