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 (the CRA rate for July 1 to September 30, 2026 — it is reset every quarter). 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.
Quick answer: when is the CRA tax filing deadline in 2026?
For the 2025 tax year, most Canadians had to file the T1 return and pay any balance owing by April 30, 2026. If you or your spouse or common-law partner were self-employed, the filing deadline was June 15, 2026 — but the payment was still due April 30. That gap is the single most expensive misunderstanding in Canadian self-employment: filing late costs you a penalty, paying late costs you daily compound interest from May 1, and the later deadline only postpones the paperwork. Estimates — confirm with your tax professional.
Last reviewed 1 September 2026. The 2025-tax-year deadlines above have passed: RRSP contributions (March 2), T4/T4A/T5 slips (March 2), the Q1 instalment (March 16), T1 filing and payment (April 30), the self-employed filing deadline (June 15), the Q2 instalment (June 15), and T2 corporate filing for a December 31 year-end (June 30).
Still ahead this year: the Q3 personal instalment on September 15, 2026, the Q4 instalment on December 15, 2026, and the single farmer/fisher instalment on December 31, 2026. If you have not filed your 2025 return, filing it now stops the late-filing penalty growing — it caps at 12 months, but interest on the balance keeps compounding daily until the balance is paid.
The next cycle, for the 2026 tax year, repeats the same pattern: information slips at the end of February 2027, then T1 filing and payment on April 30, 2027 and self-employed filing on June 15, 2027 (both fall on weekdays, so no weekend shift applies). The end-of-February 2027 slip deadline lands on a Sunday, so confirm the exact business day with the CRA closer to the time rather than assuming February 28.

Self-employed Canadians: your filing deadline is June 15, but your payment deadline is April 30. If you wait until June to pay, you'll owe two months of interest — at 7% compounded daily — on any unpaid balance.

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%.
If you have already missed a deadline and want the full picture — including how the US failure-to-file and failure-to-pay penalties differ, what happens when you are owed a refund instead of owing tax, and an ordered list of what to do today — see what happens if you miss the tax filing deadline.
Sources: the penalty percentages above come from the CRA's late-filing penalty page, and the 7% daily-compound interest figure is the CRA prescribed interest rate for overdue taxes in effect from July 1 to September 30, 2026. The CRA resets that rate every quarter — check the current quarter before relying on the number. Estimates — confirm with your tax professional.
File on time even if you can't pay the full amount. The late-filing penalty is separate from interest on unpaid tax. Filing on time and paying what you can is always better than filing late — the late-filing penalty is charged on top of interest on unpaid balances.
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:
| Reporting Period | Filing & Payment Deadline |
|---|---|
| Annual (self-employed, Dec 31 fiscal year) | June 15, 2026 (filing) / April 30, 2026 (payment) |
| Annual (non-self-employed, Dec 31 fiscal year) | March 31, 2026 |
| Quarterly | One month after each quarter: Apr 30, Jul 31, Oct 31, Jan 31 |
| Monthly | One month after each reporting month |
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:
| Quarter | Due Date |
|---|---|
| Q1 | March 16, 2026 (Mar 15 is a Sunday) |
| Q2 | June 15, 2026 |
| Q3 | September 15, 2026 |
| Q4 | December 15, 2026 |
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.
Track expenses throughout the year, not just at tax time. ExpenseBot scans your Gmail overnight and auto-categorizes receipts as they come in. By April, your expense spreadsheet is already done — no scramble required.
ExpenseBot is an expense tracker that reads receipts out of your Gmail into a Google Sheet you own, so a T1 or T2125 deadline is a transcription job rather than a reconstruction job. If you file outside Canada as well, our tax filing deadlines by country page carries the self-employed filing deadline, tax year and authority for 40+ countries, and is generated from the same deadline configuration this page is checked against. For the Canadian forms themselves, see the T2125 expense tracker and Canadian expense tracking guides.
Estimates — confirm with your tax professional. Deadlines on this page are checked against the CRA's own published dates; where a date falls on a weekend or a CRA-recognized public holiday, the CRA treats a payment or return as on time if it is received the next business day.
