Important Tax Due Dates and Limits for the 2025 Canadian Tax Year

Understanding when your taxes are due can save you from late-filing penalties and interest charges. In Canada, the tax year for individuals generally runs by calendar year (January 1 – December 31), and deadlines can vary slightly depending on your circumstances — especially if you are self-employed or a corporation. Below is your complete guide to major due dates, payment deadlines, and key contribution dates for the 2025 tax year.

📅 1. Personal Income Tax Deadlines (Individuals)

🧾 Filing Your Return

April 30, 2026 – Deadline to file your 2025 individual income tax and benefit return for most Canadians. (Canada)
June 15, 2026 – Deadline for self-employed individuals and their spouse/common-law partner to file, though any taxes owing are still due by April 30, 2026 to avoid interest. (Canada)

💰 Payment Deadline

April 30, 2026 – Deadline to pay any balance owing on your 2025 taxes. Filing later (e.g., June 15) won’t delay the payment deadline. (Canada)

📌 2. RRSP Contribution Deadline

March 2, 2026 – Last day to contribute to a Registered Retirement Savings Plan (RRSP) for the 2025 tax year. This deadline also applies to Pooled Registered Pension Plans (PRPPs) and similar registered plans. (Canada)

Contributing by this date allows you to claim those contributions on your 2025 tax return (filed in 2026), potentially lowering your taxable income for the year. (Canada)

📊 Corporate Tax Filing

A corporation’s T2 corporate tax return is generally due within six months after the end of its fiscal year (e.g., if your fiscal year ends on December 31, 2025, the return is due by June 30, 2026). (Canada)

💼 Corporate Tax Payments

Instalment payments: Corporations often must make periodic instalment payments (monthly or quarterly) throughout their tax year if their tax payable exceeds $3,000. For a calendar-year corporation, instalments are typically due March 31, June 30, September 30, and December 31, 2025. (Canada)
Balance-due payment: The remaining tax owing for the year is generally due two months after the end of the fiscal year (three months for eligible Canadian-controlled private corporations meeting specific conditions). (Canada)

💼 4. GST/HST Filing and Payment Deadlines

GST/HST filing and payments depend on your reporting period: monthly, quarterly, or annually. If you report annually and have a December 31 year end:

Payment due: April 30, 2026
Filing deadline: June 15, 2026 for GST/HST returns. (Canada)

Quarterly instalment dates for GST/HST often fall within one month after each fiscal quarter ends (e.g., April 30, July 31, October 31, January 31). (Canada)

📊 5. Tax Instalments for Individuals

Some individuals must pay their taxes by instalments (quarterly) — for example, if your net tax owing in the current or previous tax year is over $3,000.

Typical instalment deadlines include:

March 15
June 15
September 15
December 15

These instalments are advance payments toward your 2026 taxes and help prevent interest on underpayments. (FBC)

🧠 6. What Happens If Deadlines Fall on Weekends or Holidays?

If a tax deadline falls on a weekend or a CRA-recognized holiday, the CRA generally considers your return or payment on time if it is received on or before the next business day. (Canada)

🛠️ Tips to Stay on Track

✅ Start early: The tax season opens well before deadlines — online filing systems like NETFILE and EFILE can begin accepting 2025 returns in early 2026.

✅ Pay even before filing: If you expect owing taxes, pay by April 30, 2026 to avoid interest, even if you plan to file later. (Canada)

✅ Track instalments: Ensure you know whether you’re required to make quarterly payments; missing them can trigger interest charges. (FBC)

📌 7. Quick Summary: Key Dates at a Glance

Date	Deadline / Event
February 23, 2026	CRA begins accepting 2025 income tax filings (in early 2026 for 2025 returns) — useful precedent but not relevant for 2025 taxes. (Canada)
March 2, 2026	RRSP contribution deadline for 2025 tax year. (Canada)
April 30, 2026	Individual tax filing and payment deadline (self-employed payment also due). (Canada)

📍 Final Takeaway

Canada’s tax deadlines are predictable, but missing them can be expensive — whether you’re an individual, self-employed professional, or a corporation. Mark these dates in your calendar, plan your instalments, and make those RRSP contributions early to take advantage of your tax benefits.
