Plain English
Say you earn around $175,000 in Ontario and put $5,000 into your RRSP before the deadline. At tax time, you'd get back about $2,248 — that's your combined 44.97% rate giving you a direct cash refund.
Show the math
Refund ≈ contribution × marginal rate. $5,000 × 44.97% = $2,248
Combined federal (26.0%) + Ontario (12.16%) at ~$175,000 income. Includes Ontario surtax effect at this income level.
Caveats
- Estimates only — actual refund depends on total deductions, credits, and exact taxable income
- If contribution pushes you into a lower bracket, blended rate applies
- Doesn't account for Pension Adjustment if you have a workplace pension
- Ontario surtax IS factored into the marginal rate shown
