See how it works

Your marginal tax rate is the rate you pay on your next dollar of income. It's not the same as your average rate — and understanding the difference is crucial for financial planning, RRSP contributions, and understanding how raises really affect your paycheque.

Marginal vs. Effective Tax Rate

Your marginal rate applies only to the portion of income in each bracket. If you earn $75,000 in Ontario, you don't pay 41% on everything — you pay 15% on the first $57,375, 20.5% on the next $17,625, plus provincial rates stacked on top. Your average (effective) combined rate on $75,000 in Ontario is closer to 27–28%.

Why the Marginal Rate Matters

The marginal rate determines the tax benefit of RRSP contributions. If your marginal combined rate is 41%, contributing $5,000 to your RRSP saves you $2,050 in taxes this year. It also determines how much of a raise you actually keep — at a 43% marginal rate, a $100 raise nets you only $5,700 after tax.
