Every February, Canadians scramble to make last-minute RRSP contributions. It's not panic. It's strategy. The RRSP deadline is one of the most useful quirks in Canada's tax system, and understanding it can mean hundreds or even thousands of dollars back in your pocket.
What Is the RRSP Deadline?
You can contribute to your RRSP and claim the deduction for the previous tax year up until 60 days after December 31. In most years, that falls on March 1 or February 28/29. So a contribution made in January or February 2026 can be applied to your 2025 tax return.
This is why you'll see "RRSP season" marketing everywhere in January and February, banks know Canadians are motivated by tax refunds.
How Does the Refund Work?
When you contribute to your RRSP, you reduce your taxable income by that amount. The tax you "overpaid" through payroll deductions comes back to you as a refund when you file.
Example: You earn $80,000 in Ottawa and you're in a combined federal-Ontario marginal tax rate of roughly 33%. A $5,000 RRSP contribution could generate a refund of around $1,650. That's real money.
The Smart Move: Contribute Early, Reinvest the Refund
Rather than waiting until February each year, set up monthly RRSP contributions throughout the year. Your money starts compounding earlier, and you're not scrambling at the last minute.
When your refund arrives in April or May, reinvest it into your RRSP (applying it to the current year's contribution room). This creates a compounding cycle, your refund becomes next year's contribution, which generates next year's refund.
T4 Contribution Receipts
Your financial institution will issue an RRSP contribution receipt, which you attach to your tax return. If you contribute in January or February, you'll get two receipts, one for contributions in the first 60 days (labeled for the current tax year or prior year, your choice) and one for the rest of the year.
You choose which year to apply the deduction to. Sometimes it makes sense to carry the deduction forward to a year when you expect higher income.
Ottawa Tax Filing Resources
If you're a newcomer and this is your first or second Canadian tax return, Ottawa has excellent free resources. The Community Volunteer Income Tax Program (CVITP) runs free tax clinics every spring at community centres and libraries across the city, in Vanier, Barrhaven, Kanata, and downtown. Volunteers help you claim your RRSP deductions correctly.
One Caution
Contributing to your RRSP just for the refund without actually needing the tax shelter isn't always optimal, especially if your income is low. But for most working Ottawa residents in a mid-to-high tax bracket, the RRSP deadline is one of the most valuable dates on the financial calendar.
