The Canada Revenue Agency has confirmed two key dates for the 2025 tax year: April 30, 2026 for most filers and June 15, 2026 for self-employed individuals. Whether you live in Ontario or Quebec, these federal deadlines apply uniformly — but payment obligations differ depending on your employment status.

When to File Canadian Taxes in 2026?

The CRA sets two primary filing deadlines for the 2025 tax year. Most individuals must file and pay by April 30, 2026. Self-employed Canadians — and their spouses or common-law partners — get an automatic extension to June 15, 2026. That extension applies specifically to filing; payment must still reach the CRA by April 30 to sidestep interest charges. CRA processed 33 million returns last season, with 93% submitted online via NETFILE and EFILE.

Personal income tax deadline

April 30 falls on a Thursday in 2026, so no weekend-adjustment rule applies this year. The CRA confirms this date marks the general filing deadline for most individuals filing 2025 returns. If you owe money and do not pay by April 30, interest starts accumulating immediately. The CRA states: “By filing and paying on time, you will avoid late-filing penalties and interest.”

Self-employed filing extension

The June 15 extension exists because self-employed taxpayers typically manage more complex records — business income, expenses, GST/HST, and possibly corporate structures. Sole proprietors and partners in partnerships follow the same self-employed personal deadlines. The extension also covers deceased persons who were self-employed.

“June 15, 2026 – This is the deadline for self-employed individuals to file their 2025 income tax and benefit return.”

Tax tip: File early even if you qualify for the June 15 extension. Filing before April 30 gives you time to correct errors and receive your notice of assessment before payment problems surface.

What Are the Main Tax Deadlines in Canada?

Beyond the personal filing dates, several other deadlines matter depending on your tax situation. These include RRSP contribution deadlines, installment payment due dates, and employer slip issuance requirements.

Corporate deadlines

Corporations with a December 31 year-end face different timelines. Non-CCPC (Canadian-controlled private corporation) tax payments are due February 28, 2026. Corporate income tax returns are generally due six months after the fiscal year-end. Businesses operating on a non-calendar fiscal year follow the same six-month rule from their year-end date.

Benefit payment dates

Installment payments for individuals who owe tax installments follow a quarterly schedule: January 20, February 20, March 16 (March 15 falls on a Sunday in 2026, so the deadline shifts to the next business day), June 15, and December 11. GST/HST annual filers who are self-employed must pay by April 30, 2026 and file by June 15, 2026.

2026 Canada Tax Deadline Calendar
Date Deadline Type Applies To
February 23, 2026 Filing season opens NETFILE / EFILE for all filers
February 28, 2026 T4 slip issuance Employers; corporate payments (non-CCPC)
March 2, 2026 RRSP contribution deadline 2025 tax year contributions
March 16, 2026 Installment payment Individuals on quarterly plan
April 30, 2026 General filing & payment Most individuals; GST/HST payment; self-employed tax payment
June 15, 2026 Self-employed filing Self-employed, spouses, deceased persons
December 11, 2026 Final installment Quarterly installment filers

The implication: the most consequential deadline — April 30 — involves both filing and payment for most Canadians, while self-employed filers must split those obligations across two dates.

Is It Better to File Taxes Early or Later?

Pros of early filing

  • Avoids the late-filing penalty if something goes wrong
  • Faster access to refunds — CRA typically processes e-filed returns within two weeks
  • Time to gather missing slips before the deadline rush
  • Earlier correction window if errors appear on your notice of assessment

Risks of waiting until deadline

  • Software slowdowns as the April 30 deadline approaches
  • Rush errors — transposed numbers, missing slips
  • Interest on unpaid taxes accrues from May 1 regardless of filing date
  • No penalty relief for late filing after June 15 for self-employed

“If you owe money, you will still need to pay by April 30, 2026, to avoid paying interest.”

Warning: A postmarked payment counts as on time, but only if the envelope is postmarked by the deadline date. Electronic payments must be received — not just initiated — by the due date.

How Late Can I Do My Taxes in Canada?

Technically, you can still file after the deadline — but the financial consequences escalate quickly. The CRA applies a late-filing penalty of 5% of any balance owing, plus an additional 1% per month for up to 12 months. For self-employed filers, interest on unpaid taxes begins on May 1, 2026 even if you file a complete return by June 15. Payments postmarked by April 30 count as on time.

Late filing penalties

Non-self-employed individuals face immediate penalty exposure after April 30. The CRA confirms: “Late filing after April 30 incurs penalties and interest for non-self-employed.” Interest compounds daily on the outstanding balance, making late payment increasingly expensive the longer you wait.

Mitigation options

If you cannot pay in full by April 30, you can still file on time to avoid the late-filing penalty while setting up a payment arrangement. CRA offers installment agreements for taxpayers who owe. The key is to file on time — the penalty for owing is far less than the penalty for not filing.

Note: Tax slips become available in CRA My Account after processing. Employers must issue T4 slips by February 28, 2026, so you should have most documents by late February if your employer is on schedule.

When Does the Tax Year Start and End in Canada?

Canada uses a calendar year basis for personal income tax. The 2025 tax year runs from January 1, 2025 through December 31, 2025. All income earned and expenses incurred during this period must be reported on returns filed in 2026.

Calendar year basis

Every province and territory follows the same calendar year for federal tax purposes. Ontario follows federal CRA rules without variation. Quebec follows federal rules for the federal return filed with the CRA, but residents must also file a separate provincial return with Revenu Quebec under its own schedule. The federal CRA deadlines for filing apply to all provinces including Ontario and Quebec, as confirmed by CRA’s own important dates page.

Provincial variations

There are no provincial variations for personal income tax filing deadlines in either Ontario or Quebec — both provinces follow the federal CRA deadlines for filing and payment. Quebec’s provincial tax return follows Revenu Quebec timelines separately. Ontario has no separate personal income tax filing deadline.

Bottom line: Self-employed Canadians in Ontario and Quebec face the same April 30 payment deadline as other filers, with a filing extension to June 15. The cost of missing the April 30 payment date is interest — compounded daily — regardless of when you eventually file. File early, pay on time, and check provincial obligations separately for Quebec residents.

Frequently Asked Questions

What is the CRA tax filing start date 2026?

NETFILE and EFILE open on February 23, 2026 for the 2025 tax year. This allows early filers to submit returns and receive refunds before the April 30 deadline.

What happens if I miss the tax deadline?

Missing the April 30 deadline triggers a late-filing penalty of 5% of any balance owing, plus 1% per month for up to 12 months. Interest accrues on unpaid amounts from May 1, 2026. Self-employed filers who miss the June 15 filing deadline face the same penalty structure.

Are taxes due earlier in Ontario?

No. Ontario follows the federal CRA deadline of April 30, 2026 for both filing and payment of personal income tax. There is no separate provincial deadline.

When are taxes due for Quebec residents?

Quebec residents must file their federal return with the CRA by the same deadlines as other Canadians — April 30, 2026 for most filers, June 15, 2026 for self-employed. They also file a separate provincial return with Revenu Quebec under Quebec’s own schedule.

Does the deadline change for installment payments?

Yes. Installment payments follow quarterly deadlines: January 20, February 20, March 16 (March 15 is a Sunday), June 15, and December 11, 2026. These are separate from the main filing deadline.

What if I owe taxes but file late?

Interest on unpaid taxes begins accruing from May 1, 2026 for all taxpayers, including self-employed. A postmarked payment by April 30 counts as on time, but electronic payments must actually be received by the deadline.

Is there a grace period for filing?

No formal grace period exists. The only automatic extension applies to self-employed individuals, who can file by June 15 instead of April 30. Payment is still required by April 30 to avoid interest charges.
