- Federal brackets are identical across the country; the provincial or territorial layer is what makes take-home pay differ by region.
- A top rate applies only to the last dollar earned, so it always overstates what a salary is actually taxed at on average.
- Each region shelters a different amount of income through its basic personal amount before charging any tax at all.
- CPP, QPP, EI and QPIP are not income tax, but they come off the same paycheque — every ladder here includes them.
How the bracket tables work
Canada taxes employment income in two layers. The federal layer is the same wherever you live; the provincial or territorial layer sits on top of it and is set by each government independently, which is why the same salary produces a different tax bill in Halifax and in Calgary.
The table above shows the second layer only — each region’s own top rate, how many brackets it splits its income scale into, and how much income its basic personal amount shelters before any tax is charged. Sorting by top rate makes the spread obvious: the gap between the highest and lowest top provincial rate is wider than the gap between two adjacent federal brackets.
Open any region for its full schedule and, underneath it, a ladder showing what six real salaries actually produce once both layers and payroll premiums are applied. That second table is the one worth reading — a top rate on its own tells you almost nothing about what you keep.
The math
Both layers work the same way. Income is divided into bands, each band has its own rate, and each rate applies only to the income inside its own band. A rate described as “the top bracket” is charged on the last dollar earned, never on the whole salary — which is why an average rate is always well below a marginal one.
Before any of that, the basic personal amount is converted to a non-refundable credit at the lowest bracket rate and subtracted from the tax owing. Federal and provincial basic personal amounts differ, so the amount of income you can earn tax-free differs by region too. The tax-free column above reports the provincial figure; the federal one applies on top of it everywhere.
The ladder on each region page adds CPP or QPP contributions, EI premiums, and Quebec’s QPIP where it applies. Those are premiums rather than income tax, but they come off the same paycheque, so leaving them out would overstate take-home by thousands a year.
Worked example
Take two regions at the extremes of the table. On the same employment income, the province with the highest top rate charges roughly ten percentage points more on the last dollar than the one with the lowest — but the average rate on a mid-range salary differs by far less, because most of that income is taxed in the lower bands where the two are much closer.
That is the practical lesson of the table: a headline top rate is a poor guide to a mid-career salary. Use the comparison pages, which compute take-home at six salaries in both regions, before drawing a conclusion from a rate alone.
Key terms
- Marginal rate
- The rate charged on the next dollar you earn. It is the rate that decides what a raise or a bonus is worth after tax.
- Average rate
- Total income tax divided by total income. Always lower than the marginal rate whenever more than one bracket is in play.
- Basic personal amount
- Income sheltered from tax by a non-refundable credit. Federal and provincial amounts are separate and both apply.
- Bracket threshold
- The income at which one band ends and the next rate begins. Most, but not all, provinces index these to inflation each year.
