Canada Tax Filing Deadlines: Tax Year, April 30, June 15 and Instalments

Canada tax filing deadlines are simpler than most people expect, but the details trip up newcomers, the self-employed and anyone who also files in the United States or India. Individuals use the calendar year as their tax year. For the 2025 tax year, most returns were due on April 30, 2026, self-employed filers had until June 15, 2026, and every balance owing was due on April 30, 2026. This page sets out those dates, the other deadlines that attach to them, the penalties for missing them, and the dates to watch for 2026 planning.

What is the Canadian tax year?

For individuals the tax year is the calendar year. A return for 2025 reports income from January 1 to December 31, 2025 and is filed in 2026. If you arrived in or left Canada during the year, you still file for the calendar year, but only the part of the year you were a resident carries worldwide income (see our Canada tax residency rules). Corporations choose their own fiscal year-end, so corporate dates move with that year-end; the T2 corporation return guide covers them.

Canada tax filing deadlines for the 2025 return

If a due date falls on a weekend or a CRA-recognized holiday, the CRA treats a return received or postmarked on the next business day as on time, and a payment received on the first business day afterward as on time.

Who gets the June 15 date?

You get until June 15 if you, or your spouse or common-law partner, carried on a business in the year. The exception is a business whose expenses are mainly tied to a tax shelter, where the date stays April 30. June 15 is only a filing extension. The balance owing must still reach the CRA by April 30, and interest runs from May 1.

Documents and information you need before the deadline

1. Last year's notice of assessment and your CRA account sign-in (see our CRA My Account guide).
2. Slips: T4, T4A, T5, T3, T5008, T4RSP and similar. If one has not arrived by the end of March, contact the issuer; many also appear in your CRA account.
3. RRSP, FHSA and charitable receipts, child care and medical receipts.
4. For foreign income, statements in the original currency so you can convert to Canadian dollars.
5. Any CRA letters, because some deadlines are set in the letter itself.

Penalties and interest for late filing and late payment

The late-filing penalty applies when you file late and owe tax. Prescribed rates reset every quarter, so check the CRA page for the quarter in which your balance is outstanding. Separate and heavier penalties apply to foreign reporting forms; see our guides on the T1135 and CRA penalties and interest. If events beyond your control caused the delay, the CRA's taxpayer relief provisions let you ask it to cancel or waive penalties and interest.

Worked example: a Calgary freelancer

Arjun, a freelance designer in Calgary, owes $3,000 for 2025. He files on August 20, 2026, which is more than two but fewer than three full months after June 15, 2026. Because his business status gave him a June 15 filing date, the late-filing penalty runs from that date: 5% ($150) plus 1% for each of two full months ($60), so $210, plus interest on the whole $3,000 from May 1, 2026. Had he filed on June 15 and paid on April 30, he would have owed neither charge.

If you missed April 30, 2026

File as soon as you can, even if you cannot pay. Filing stops the monthly penalty growing, gets benefits and RRSP room moving again, and starts the CRA's clock for assessing you. Then arrange payment through your CRA account or by calling to set up an arrangement. If you have several unfiled years or unreported foreign income, speak with your Canadian CPA about the Voluntary Disclosures Program before the CRA contacts you; see our CRA voluntary disclosures guide.

Planning dates for 2026 and 2027

• December 15, 2026: last 2026 instalment date.
• December 31, 2026: the cut-off for FHSA contributions you want to deduct for 2026 (for 2025 the CRA allowed up to $8,000 of contributions made by December 31, 2025 to be claimed), for donations that count on the 2026 return, and for realizing capital losses in 2026.
• First 60 days of 2027: the window for RRSP contributions that you can still deduct on the 2026 return.
• April 30, 2027 and June 15, 2027: statutory dates for 2026 returns. The CRA confirms the full list of 2027 dates once it publishes them.

If you also file in the U.S. or India

A Canadian resident with a green card, U.S. citizenship or an Indian bank account may have three separate calendars. Build one master list: our Canada CRA deadline calendar, the U.S. federal tax calendar for 2026 and 2027 and the three-country deadline comparison help. For extension rules in each country, read tax extensions by country.

Mistakes to avoid

• Assuming the June 15 self-employed date also delays payment. It does not.
• Forgetting that your spouse's self-employment gives you the later filing date but not a later payment date.
• Missing the 60-day RRSP window because the calendar date shifts when it lands on a weekend.
• Waiting for slips that never come. Report all income even if a slip is missing.
• Ignoring a CRA letter with its own deadline, which overrides the general calendar.
