As tax season approaches, many Canadians begin gathering their paperwork and planning their filings. Whether you’re a first-time filer or a seasoned taxpayer, understanding how Personal Tax Filing (T1) works — and what documents you may need — can help you avoid delays, reduce stress, and ensure you’re maximizing your return.
Below is a simple overview to help you stay organized and on time this year.

What Is a Personal Tax Return (T1)?
A T1 General Return is the standard income tax and benefit return that all individuals in Canada must file each year. It reports your total income, calculates federal and provincial tax, and determines your eligibility for benefits, credits, and refunds.
Most Canadians must file a T1 return even if their income is low or tax was already deducted at source.
Key Filing Deadlines
✔ April 30 2026 — Most individuals must file their personal tax return by April 30 each year. Any balance owing is also due April 30.
✔ June 15 2026 — Self-employed individuals and their spouses/common-law partners have until June 15 to file — but any balance owing is still due April 30.
✔ March 1 2026 — RRSP contributions for the previous tax year must be made by March 1 to be deductible (or the next business day if March 1 falls on a weekend).
✔ December 31 2025 — FHSA (First Home Savings Account) contributions must be made by December 31 of the calendar year to be claimed as a deduction for that year. Unlike RRSPs, there is no 60-day grace period after year-end for FHSA contributions.
Filing early ensures faster refunds and avoids interest charges on late payments.
Documents You May Need for Your T1 Return
Below is a comprehensive list of slips, receipts, and documents that may apply to your situation.
