Every year, Canadians prepare for tax season by gathering documents, reviewing deductions, and filing their returns with the Canada Revenue Agency . If you’re wondering when tax season in Canada starts, when it ends, and what the deadlines are for filing 2025 taxes in 2026, this guide explains everything you need to know.
Understanding the Canadian tax calendar helps individuals and businesses avoid penalties, file on time, and potentially receive refunds sooner.
When Is Tax Season in Canada?
In Canada, tax season generally begins in late February and runs through April for most individuals. For the 2026 tax season (filing your 2025 income), the key dates are expected to be:
-
Tax filing opens: Late February 2026
-
Personal tax filing deadline: April 30, 2026
-
Self-employed filing deadline: June 15, 2026
-
Tax payment deadline: April 30, 2026
This means even if you are self-employed and have until June to file your return, any taxes owed must still be paid by April 30, 2026 to avoid interest charges.
When Is Tax Season 2026 for 2025 Taxes?
If you are searching “when is tax season in Canada”, you are likely referring to the filing period for your 2025 income, which takes place in 2026. Below are the key deadlines for filing:

When Is Canadian Tax Season for Corporations?
Corporate taxes follow a different schedule compared to personal taxes.
In Canada, corporate tax returns must be filed within six months after the end of the corporation’s fiscal year.
For example:
|
Business Fiscal Year End |
Corporate Tax Filing Deadline |
|
December 31, 2025 |
June 30, 2026 |
|
March 31, 2026 |
September 30, 2026 |
|
June 30, 2026 |
December 31, 2026 |
However, corporate taxes owed are usually due two or three months after the fiscal year end, depending on the size of the business and eligibility for the small business deduction.
This is why many businesses work with professional bookkeepers or accountants to ensure accurate and timely filing.
When Is Tax Season Over in Canada?
Many Canadians ask “when is tax season over?”
For most individuals, tax season is considered over after April 30, which is the primary filing deadline. However, it extends later for some taxpayers:
-
Self-employed individuals: June 15, 2026
-
Corporations: Six months after fiscal year end
Even after tax season ends, taxpayers can still file late returns or correct previously submitted returns, though late filing penalties and interest may apply.
Why Filing Early During Tax Season Matters
Filing your taxes early can provide several benefits.
Faster Refunds
If you are expecting a refund, filing early allows the CRA to process your return sooner.
Reduced Risk of Penalties
Submitting your return before the deadline helps avoid late filing penalties and interest.
Time to Resolve Issues
If additional documentation is needed, filing early gives you time to respond before the deadline.
