Canadian Tax Deadlines 2026: Every Date You Need (CRA Filing Guide)

Tax deadlines in Canada are more confusing than they should be. If you're self-employed, you have a different filing deadline than payment deadline — and mixing them up is the single most expensive mistake Canadian freelancers make.

Miss a CRA deadline and you're looking at a 5% penalty on your unpaid balance, plus 1% per month for up to 12 months. On top of that, interest accrues at 7% compounded daily (as of Q2 2026). For repeat offenders, the penalties double.

This guide covers every tax deadline for individuals, self-employed, corporations, and GST/HST filers for the 2026 calendar year (covering the 2025 tax year). Bookmark it and check back throughout the year.

2026 Canadian Tax Deadline Calendar

Personal Tax Filing (T1)

Most Canadians must file their T1 personal income tax return and pay any balance owing by April 30, 2026. This covers employment income, investment income, rental income, and most other personal income sources for the 2025 tax year.

If you owe the CRA and file late, the penalty is:

• 5% of the unpaid tax owing at the filing deadline
• Plus 1% per full month the return is late
• Up to a maximum of 12 months (total maximum penalty: 17%)

For repeat late filers (if the CRA assessed a late penalty in any of the 3 preceding years and issued a formal demand to file), the penalties are harsher: 10% plus 2% per month, up to 20 months — a maximum of 50%.

Self-Employed Tax Filing (T2125)

If you or your spouse/common-law partner are self-employed, your T1 filing deadline extends to June 15, 2026. However — and this is the part that trips everyone up — your payment deadline is still April 30.

This means interest on any unpaid balance starts accruing May 1, even though you still have six more weeks to file the return. At 7% compounded daily, that's not trivial.

Your T2125 (Statement of Business or Professional Activities) is filed as part of your T1 return. It includes your business income, expenses by category, home office costs, and motor vehicle expenses. Common T2125 expense categories include:

• Advertising (line 8521)
• Meals and entertainment at 50% (line 8523)
• Motor vehicle expenses (line 9281)
• Office expenses (line 8810)
• Supplies (line 8811)
• Professional fees (line 8860)
• Phone and utilities (line 8220)
• Rent (line 8910)
• Insurance (line 8690)
• Travel (line 9200)

ExpenseBot auto-categorizes your expenses to these CRA line items, so you don't need to memorize line numbers. It also tracks GST/HST for input tax credits and calculates vehicle deductions at the current CRA mileage rate (73¢/km for the first 5,000 km, 67¢/km after).

Corporate Tax Filing (T2)

Corporations must file their T2 return within 6 months after their fiscal year-end. For corporations with a December 31 year-end, the filing deadline is June 30, 2026.

The payment deadline is different — and earlier:

• General rule: Tax balance due 2 months after fiscal year-end (March 1, 2026 for Dec 31 year-end)
• Qualifying CCPCs: Canadian-Controlled Private Corporations that claimed the small business deduction and whose taxable income (with associated corporations) didn't exceed $500,000 get 3 months (March 31, 2026 for Dec 31 year-end)

GST/HST Filing Deadlines

Your GST/HST filing deadline depends on your reporting period:

You must file a GST/HST return for every reporting period, even if you had no sales or owe nothing (a "nil return"). Tracking your Input Tax Credits (ITCs) is important — every business expense with GST/HST can be claimed back. This is another area where proper expense tracking pays for itself.

RRSP Contribution Deadline

The RRSP contribution deadline for the 2025 tax year is March 2, 2026 (the statutory 60-day mark falls on March 1, which is a Sunday, so it moves to Monday). Contributions must be received by 11:59 PM in your time zone.

This isn't directly related to expense tracking, but it's one of the most important tax deadlines for Canadians, so we're including it here. Max out your RRSP if you can — it's the most straightforward way to reduce your tax bill.

Instalment Payment Deadlines

If you owed more than $3,000 in taxes in two consecutive years (or your net tax owing exceeds $3,000 for 2025 and either 2024 or 2023), the CRA expects you to make quarterly instalment payments:

The CRA offers three calculation methods for instalments:

• No-calculation option: Use the instalment amounts from your most recent CRA notice
• Prior-year option: Base each payment on last year's tax owing, divided by 4
• Current-year option: Estimate this year's tax and divide by 4 (risky — if you underestimate, you'll owe interest)

Farmers and fishers have a single instalment deadline of December 31, 2026.

How to Prepare for Each Deadline

Here's a 4-week pre-deadline checklist that works for any tax filing:

Week 4 (4 weeks before deadline): Gather all receipts and income documents. If you use ExpenseBot, your Gmail receipts are already organized — run a scan to catch anything recent.

Week 3: Categorize expenses and reconcile bank statements. For T2125 filers, make sure every expense is assigned to the correct CRA line item. Check your mileage log is complete.

Week 2: Complete your tax forms or send everything to your accountant. If you're using ExpenseBot, share your Google Sheets expense report directly — your accountant gets view access instantly.

Week 1: File and pay. Don't wait for the last day — CRA's online systems can be slow during peak filing periods.
