RRSP · 2026
What an RRSP deduction changes in 2026 tax.
By Vishal Tomar · Checked against official sources · Updated 13 November 2026
The 2026 RRSP dollar limit is $33,810.00, from the CRA limits table. New room is 18% of the prior year's earned income, from the deduction-limit page. This tool does not apply either limit. If you are in your first year, start with the year-one room calculator before you treat a contribution as deductible.
Brackets and the basic personal amount are the 2026 figures already used on the take-home page. Quebec uses the simplified provincial estimate, and the federal side includes the 16.5% abatement. CPP, EI, and the Canada employment amount are not part of the difference.

CPP, QPP, EI, QPIP, and the Canada employment amount are left out of both sides, because an RRSP deduction does not change them. The basic personal amount is included, because it depends on income. This is not a notice of assessment, and it does not check whether you have the room to deduct the contribution.
Questions
Is this the refund on my notice of assessment?
No. It is the difference in 2026 income tax when the income you enter is reduced by the contribution. A real refund also depends on tax already withheld, other deductions, and whether you have the room to deduct the contribution.
Why might the percentage not match one bracket?
A contribution that crosses a bracket, the federal basic-personal-amount phase-out, Ontario surtax, or the Ontario Health Premium changes more than one rate. The result is the difference between two full calculations, not a single rate times the contribution.
What if I have no RRSP room?
A newcomer often has $0 of new room in the year they arrive. The 2026 ceiling is $33,810, and it is a cap on 18% of the prior year's earned income, not a starter amount. This page does not apply that cap.
