On a $75,000 single salary with a $5,000 RRSP contribution in 2026, Ontario models about $1,922 in tax savings (38.4% effective on that band). Provincial brackets — not a city wage tax — drive how much each deductible dollar is worth versus Alberta or Ontario.

An RRSP contribution is generally deductible: it lowers the income you report for federal and Ontario provincial tax (up to your personal CRA deduction limit). You save tax at your combined marginal rate — so the same dollar usually saves more when you are in a higher bracket.
Ontario's top provincial rate is about 13.16%. Federal brackets are the same nationwide; provincial Form 428 (or Québec’s return with federal abatement in our engine) is what makes Ontario differ from Alberta or Ontario on this calculator.
Use the calculator above with your salary, contribution, and filing status to see tax with and without RRSP, take-home change, and the net after-tax cost of the contribution.
Single filer, $75,000 salary, $5,000 RRSP: modeled tax savings ≈ $1,922; take-home with RRSP ≈ $52,538; net cost of the contribution ≈ $3,078.
Single filer, $120,000 salary, $10,000 RRSP: modeled tax savings ≈ $3,881 (effective rate on the contribution ≈ 38.8%).
Same $5,000 contribution at $75,000: Ontario ≈ $1,922 vs Ontario ≈ $1,922 vs Alberta ≈ $1,815. Provincial rates — not a municipal tax — drive the gap.
Federal income tax is national. Provincial and territorial rates (and Québec’s distinct stack) change how much each deductible dollar is worth.
Higher-tax provinces typically show larger modeled RRSP savings on the same salary and contribution. Lower-tax jurisdictions (e.g. Alberta) still benefit from the federal deduction, but the provincial slice is smaller.
Residence on December 31 of the tax year decides which provincial brackets apply. Working in another province does not change that rule for this calculator.
For 2026, the CRA RRSP dollar limit is $33,810. New room for the year is generally the lesser of 18% of prior-year earned income and that dollar limit, plus unused room, minus pension adjustments.
Earned income for RRSP purposes includes employment and self-employment income and certain other amounts — not interest, dividends, capital gains, or pension income. Your personal limit appears on your Notice of Assessment or Form T1028.
This calculator estimates tax savings for a chosen contribution amount; it does not verify whether you have enough room. Over-contributions can attract a 1% per month tax on excess above the $2,000 lifetime buffer (CRA).
Use it before a lump-sum contribution (including the first-60-days window), when setting payroll RRSP amounts, or when comparing offers that include RRSP matching in Ontario.
Pair it with the TFSA calculator if you are choosing between accounts, and with the Canada paycheck calculator if you need CPP/EI detail on the full pay stub.
Withdrawals (outside HBP/LLP) are taxable; HBP and LLP have separate CRA repayment rules not modeled in the savings estimate above.
With a top provincial rate near 13.16%, deferring tax from peak earning years into lower retirement brackets is often the goal. See: You earn more now than in retirement (saves tax at higher rate today); You want to reduce taxable income this year.
You expect a higher income in retirement than now You want flexibility — no tax on withdrawal ever You're in a low tax bracket now (small upfront deduction benefit)
18% of your prior year net earned income, up to $33,810 for 2026. Unused room accumulates and carries forward indefinitely. Your personal limit appears on your CRA Notice of Assessment.
Annual ceiling before unused room. Your personal limit is still the lesser of 18% of prior-year earned income and the dollar limit for that year (CRA).

The same contribution saves different amounts across provinces. Switch to any province below for a dedicated calculator.
The tax savings, take-home amounts, and net cost of your RRSP contribution above come from the salary, province, filing status, and contribution you enter—not a third-party feed. We run your income through the same Canada paycheck tax engine twice: once at full salary and once with taxable income reduced by your RRSP deduction. The difference is your estimated tax savings at your combined federal and provincial marginal rate (plus CPP, EI, and Ontario Health Premium effects). Below are the formulas, the order we follow, and worked examples you can check by hand.
| Line | Formula |
|---|---|
| Taxable income with RRSP | max(0, annual salary − RRSP contribution) |
| Total tax without RRSP | Federal + provincial tax + CPP/QPP + EI + Ontario Health Premium (if ON) |
| Total tax with RRSP | Same engine on (salary − RRSP contribution) |
| RRSP tax savings | Total tax without RRSP − total tax with RRSP |
| Take-home without RRSP | Salary − total tax without RRSP |
| Take-home with RRSP | Salary − RRSP contribution − total tax with RRSP |
| Net cost of contribution | RRSP contribution − tax savings |
| Effective marginal rate on contribution | Tax savings ÷ RRSP contribution |
Calculate tax at full salary
Run calculateTax(salary) for your province and filing status
We compute federal brackets, provincial brackets, Basic Personal Amount credits, CPP or QPP, EI, and Ontario Health Premium on your full annual salary. This is your baseline before any RRSP deduction.
Calculate tax after RRSP deduction
Run calculateTax(salary − RRSP contribution)
RRSP contributions reduce taxable income dollar-for-dollar (up to your deduction limit). We run the same tax engine on the lower income—CPP and EI bases also drop slightly because pensionable earnings fall.
Compute tax savings
Total tax without − total tax with
The difference in total tax and payroll charges is your estimated annual tax savings from the contribution. This approximates your combined marginal rate on the last dollars of the contribution.
Compare take-home pay
Cash after taxes, with RRSP dollars set aside
Take-home with RRSP assumes you contribute the entered amount from gross pay, then pay tax on the reduced taxable income. Your liquid cash is lower than without RRSP, but you hold the contribution in your RRSP.
Net cost and marginal rate
Net cost = contribution − savings; rate = savings ÷ contribution
Net cost is what the contribution effectively costs you after the tax refund or reduced withholding. The marginal rate shows what percentage of each contributed dollar came back as tax savings.
$75,000 salary · $5,000 RRSP · Single · Ontario · 2026
Tax without RRSP on $75,000 = $19,384 total tax & payroll
Tax with $5,000 RRSP (taxable $70,000) = $17,462
$19,384 − $17,462 = $1,922 tax savings (38.4% effective rate)
Net cost: $5,000 contribution − $1,922 savings = $3,078 out of pocket

Provincial rates change your savings: $5,000 at $75,000 saves $1,922 in Ontario vs $1,815 in Alberta.
Zero contribution: No RRSP contribution — tax savings are zero → tax savings $0.
Larger contribution: Large contribution: $15,000 RRSP on $120,000 salary → saves $5,508 (36.7% rate).

What we do not model on this page
We compare two annual tax scenarios only—we do not validate your personal RRSP deduction limit, pension adjustment (PA), spousal RRSP attribution rules, HBP or LLP withdrawals, carry-forward deduction claims, or first-60-days contribution timing. RRSP withdrawals, RRIF minimums, and OAS clawback are not modeled. Quebec abatement and provincial surtaxes use the same engine as our Canada paycheck calculator. Your employer may withhold differently than this estimate; use your T4 and Notice of Assessment for filing.
