What it’s for
- Knowing what a is worth (, ): it saves tax at your marginal rate.
- Knowing how much of a raise you’ll actually keep.
Who it’s for
- Anyone who pays tax, especially if you’re deciding between an RRSP and a .
How it works
Tax works in brackets: each rate only applies to the dollars inside its bracket. Federally, from 14% on the first $58,523 to 33% at the top; in Québec, from 14% to 25.75%.
Moving into the next bracket never lowers your after-tax income: only the extra dollars are taxed more.
Credits and benefits that shrink as income rises can make your real marginal rate higher than the bracket tables suggest.

Common mistakes
- “A raise will bump me into a higher bracket and I’ll lose money”: false, only the extra dollars are taxed more.
- Judging an RRSP by your average rate: it’s the marginal rate that counts.
- Forgetting your marginal rate changes in retirement: comparing the two shows you whether the RRSP is worth it.
