RRSP Deduction Deadline Calculator
Track the countdown to the 2026 RRSP deadline and estimate your immediate tax savings.
The 'First 60 Days' Rule
In Canada, the RRSP contribution deadline for a given tax year is usually the 60th day of the following calendar year. For the 2025 tax year, the deadline is March 2, 2026.
Contributions made during this window can be applied to either your 2025 or 2026 tax returns, giving you valuable flexibility in tax planning.
How to Use This Calculator
- Expected Income - Enter your total taxable income for the previous calendar year (2025).
- Contribution Amount - Enter the total amount you plan to deposit into your RRSP before the March deadline.
- Check Impact - The calculator shows exactly how much tax you save by hitting the deadline.
Calculation Formula & Example
The Formula
Refund = Contribution × Marginal Tax Rate
Where:
- Deadline = The 60th day of the calendar year.
- Marginal Rate = The tax rate on your last dollar of income (combined Federal + Provincial).
Example Calculation
If you contribute $10,000 on Feb 20, 2026, and your tax rate is 40%, you receive a $4,000 refund in April 2026. If you wait until March 5, you won't get that $4,000 until April 2027.
Benefits of Using This Calculator
- Accelerated Refunds - Get your tax money back months earlier by contributing before the cutoff.
- Tax Planning Flexibility - Choose which year to claim the deduction based on your income trajectory.
- Avoid Missed Opportunities - Once the deadline passes, you cannot back-date contributions to the previous year.
Calculator Use Cases
Many companies pay bonuses in February. Use this to shelter that bonus from tax immediately.
If you realize you owe money for 2025, a last-minute RRSP contribution can bring that bill down to zero.
