Canadian Tax Deadlines for 2026
Reviewed by EverStone CPA · July 2026
Every CRA deadline a small-business owner needs — corporate tax, personal tax, GST/HST, payroll and slips — in one plain-English calendar. Bookmark it, or let us track them all for you. Maintained by EverStone CPA, an Abbotsford, BC firm serving businesses Canada-wide.
Quick answer: The Canadian tax deadlines that cost money are usually the payment deadlines, not the filing ones. A T2 corporate return is filed six months after your fiscal year-end, but the balance owing is due within two to three months for most small corporations. Personal tax (T1) is due April 30 — June 15 to file if self-employed, but pay by April 30. GST/HST, payroll and slips each have their own dates below.

Your corporation’s exact deadlines
Enter your fiscal year-end and get your dates — payment, filing and GST.
Dates that land on a weekend or public holiday shift to the next business day — and instalment obligations may apply through the year. General information, not advice.
Corporate tax (T2)
Your fiscal year-end sets your dates — most owners get the two mixed up.
| Deadline | When |
|---|---|
| Balance owing | 3 months after fiscal year-end (CCPC claiming the small-business deduction); 2 months otherwise. Interest starts the day after. |
| T2 return filing | 6 months after fiscal year-end. Late filing brings penalties on top of interest. |
| Corporate instalments | Monthly or quarterly through the year if your prior tax exceeded the threshold. |
Personal tax (T1)
| Deadline | When |
|---|---|
| Filing (most people) | April 30, 2026. |
| Filing (self-employed) | June 15, 2026 — but any balance owing is still due April 30. |
| Balance owing | April 30, 2026 (for everyone, including the self-employed). |
| RRSP contribution | March 2, 2026 (first 60 days) to count for the 2025 tax year. |
| Personal instalments | March 15, June 15, September 15, December 15. |
GST/HST
Frequency depends on your revenue and what you elected.
| Deadline | When |
|---|---|
| Annual filer (Dec 31 year-end) | File by June 15; balance owing due April 30. |
| Annual filer (other year-end) | File and pay 3 months after your fiscal year-end. |
| Quarterly filer | 1 month after the end of each quarter. |
| Monthly filer | 1 month after the end of each month. |
Payroll & information slips
| Deadline | When |
|---|---|
| Source deductions (regular remitter) | 15th of the month after you pay employees. |
| T4 / T5 slips | Filed with the CRA and given to recipients by the last day of February (March 2, 2026). |
| T5018 (construction subcontractors) | 6 months after your reporting-period end. |
Dates reflect 2026 CRA deadlines; where a deadline falls on a weekend or holiday the CRA generally accepts the next business day. This is general information, not advice specific to your situation — we confirm your exact dates as part of your engagement.

What owners say about working with us
Verified 5-star Google reviews from EverStone CPA clients.
“I have worked with Sunny for the past 2 years. He is very knowledgeable and has saved me tons in taxes by restructuring my group of companies — the best accountant I've worked with in the last 10 years, after switching from three different firms.”
“Highly recommend working with Sunny. We switched to him last year for both our personal and small-business taxes — responsive, knowledgeable and quick.”
“Personal. Professional. Responsive. Plus he saved me a bundle!”
Meeting the deadline and paying the balance are separate problems. If you can file on time but not pay, a CRA payment arrangement is the route that keeps penalties from stacking on top of interest.
