April 30 vs. June 15 explained. Late filing penalties, payment deadlines, and what happens if you miss the date.
Understanding the Canadian tax filing deadlines for 2026 is critical to avoiding costly penalties and interest charges. While most Canadians face a single April 30 deadline, self-employed individuals and their spouses get an extended filing window — but the payment deadline is the same for everyone. Here's everything you need to know.
This is the deadline for most Canadians to file their 2025 personal income tax return (T1). It applies to employees, retirees, students, and anyone who is not self-employed. If April 30 falls on a weekend or holiday, the deadline moves to the next business day — in 2026, April 30 is a Thursday.
Also the payment deadline: Any taxes owing for 2025 must be paid by April 30, 2026, even for self-employed individuals who have until June 15 to file.
If you or your spouse/common-law partner carried on a business in 2025 (including freelancing, consulting, gig work, or operating a sole proprietorship), you have until June 15, 2026 to file your return. This also applies to your spouse's return, even if they have no self-employment income themselves.
Critical warning: Despite the June 15 filing deadline, any balance owing is still due by April 30, 2026. If you pay after April 30, interest will accrue from May 1 even if you file by June 15.
Canadian corporations must file a T2 return within 6 months of the end of their fiscal year. The balance owing is due 2 or 3 months after the fiscal year end (depending on the type of corporation). Corporate deadlines are separate from personal deadlines.
The CRA considers you self-employed if you operate a business either alone or as a partner. This includes:
If you received a T4 from an employer AND also had self-employment income, you are considered self-employed for deadline purposes and can file by June 15 — but again, any balance is due April 30.
The CRA's late filing penalty is applied automatically when you file after the deadline and have taxes owing. It is calculated as follows:
| Situation | Penalty |
|---|---|
| First late filing in 3 years | 5% of balance owing + 1% per month (up to 12 months) |
| Filed late in any of previous 3 years | 10% of balance owing + 2% per month (up to 20 months) |
| Repeated failure to report income | Additional 10% federal + 10% provincial penalty on unreported amount |
The CRA charges compound daily interest on any unpaid amounts starting May 1, 2026 (the day after the April 30 deadline). The prescribed interest rate is set quarterly by the CRA and is currently 9% per year (as of Q1 2026). This is higher than most savings accounts and many investment returns — always prioritize paying your tax bill.
Interest is also charged on late instalment payments (if you're required to pay quarterly instalments) and on penalties. Interest compounds daily, meaning interest accrues on previously accrued interest.
This is one of the most important things to understand: filing on time and paying on time are two separate obligations. If you cannot pay your full tax bill by April 30, you should still file your return by the deadline. Here's why:
The RRSP contribution deadline deserves special mention because it falls before the tax filing deadline. Any RRSP contributions made between January 1 and March 1, 2026 can be applied to either your 2025 or 2026 tax return (your choice). Contributions after March 1, 2026 can only be applied to the 2026 tax year.
Your RRSP contribution room for 2025 is 18% of your 2024 earned income, up to a maximum of $32,490 (2025 RRSP dollar limit), minus any pension adjustment. Your exact room is shown on your 2024 Notice of Assessment or in CRA My Account.
When April 30 falls on a Saturday, Sunday, or federal statutory holiday, the CRA extends the deadline to the next business day. For 2026, April 30 is a Thursday, so there is no extension. However, if you're uncertain, always check the CRA's official website or CRA My Account for confirmation of applicable dates each year.
While federal and provincial income taxes are filed together on one T1 return for most Canadians, Quebec residents file a separate provincial return with Revenu Québec. The provincial deadline generally mirrors the federal April 30 deadline, but Revenu Québec has its own rules for late filing and penalties. Self-employed Quebecers still get the June 15 extension from Revenu Québec as well.
