Tax season in Canada is an important time for individuals, self-employed professionals, and businesses. Knowing when tax season starts, along with key Canada Revenue Agency (CRA) deadlines, helps you file accurately, avoid penalties, and receive refunds on time.
In this guide, we break down when tax season begins in Canada, the most important CRA dates, and how early preparation can make the filing process smoother.
When Does Tax Season Start in Canada?
In Canada, tax season typically starts in late February each year. This is when the Canada Revenue Agency (CRA) begins accepting income tax and benefit returns through electronic filing systems such as NETFILE and EFILE.
For the 2026 tax year, the CRA begins accepting tax returns on:
📅 February 23
From this date onward, taxpayers can officially submit their personal and business tax returns to the CRA.
Key CRA Tax Dates You Should Know
Understanding CRA deadlines is essential to staying compliant and avoiding late-filing penalties. Below are the most important dates to keep in mind:
📌 February 23 – Tax Filing Opens
- CRA begins accepting electronic tax returns
- Personal, self-employed, and corporate returns can be submitted
- Early filers may receive refunds sooner
📌 April 30 – Personal Tax Filing Deadline
- Deadline for most individuals to file and pay their income taxes
- Late filing may result in penalties and interest
📌 June 15 – Self-Employed Filing Deadline
- Deadline to file for self-employed individuals and their spouses
- Any tax owing must still be paid by April 30 to avoid interest charges
📌 Ongoing – Corporate Tax Deadlines
- Corporate filing deadlines depend on the company’s fiscal year-end
- Payment deadlines may differ from filing deadlines
Why Filing Early Matters
Filing your tax return early in the season offers several advantages:
- ✅ Faster CRA refunds
- ✅ Reduced risk of last-minute errors
- ✅ More time to address missing documents
- ✅ Lower stress and better financial planning
Many tax slips, such as T4s, T5s, and investment statements, are issued by employers and institutions by late February. Preparing early ensures nothing is missed.
What You Should Prepare Before Tax Season Starts
Before submitting your tax return, make sure you have:
- Income slips (T4, T5, T3, T4A, etc.)
- Expense records (especially for self-employed individuals)
- RRSP contribution receipts
- Tuition, childcare, and medical expense records
- Previous year’s Notice of Assessment
Proper documentation helps ensure accuracy and CRA compliance.
Professional Tax Support Makes a Difference
Canadian tax rules can be complex, especially for self-employed individuals and corporations. Working with a professional tax advisor or CPA can help:
- Ensure accurate and compliant filing
- Identify eligible deductions and credits
- Reduce the risk of CRA reviews or reassessments
- Save time and provide peace of mind
