- On $100,000, Alberta leaves you with $5,713 more a year after income tax and payroll deductions.
- The marginal rate on that salary is 30.5% in Alberta and 38% in Nova Scotia.
- The gap is not a fixed percentage — it moves with income, which is why six salaries are shown rather than one.
- Sales tax, property tax and household-specific credits are outside these figures and can outweigh a small gap.
How Alberta and Nova Scotia compare
Federal tax is identical in Alberta and Nova Scotia, and so are CPP or QPP and EI. Everything that differs between these two regions is the provincial or territorial layer — which is why a comparison that only quotes the top rates overstates the gap so badly.
On $100,000, Alberta leaves $72,656 and Nova Scotia leaves $66,943. That is a difference of $5,713 a year, in favour of Alberta. At $40,000 the same pair differs by only $1,643, because most of a smaller salary is taxed in the bands where the two schedules are closest.
The tables above show six salaries because that shape matters more than any single row. A pair that looks nearly level in the middle of the range can separate sharply at the top, once the higher-rate bands finally carry real weight.
How these figures are calculated
Both columns come from one engine call each, at the same salary. It computes federal tax on the federal bracket schedule, provincial or territorial tax on each region’s own schedule, applies the basic personal amount as a non-refundable credit at both levels, then subtracts CPP or QPP contributions and EI premiums up to their annual maximums — plus QPIP where Quebec is one of the two regions.
The difference column is a subtraction of those two results, not a rate difference multiplied by a salary. Marginal rates are measured by computing tax at the salary and at the salary plus a small increment, so credit phase-outs and surtaxes are captured rather than assumed away.
What is not modelled: sales tax, property tax, provincial health premiums, employer benefits and every credit beyond the basic personal amount. On a gap this size those can easily be the deciding factor, and none of them can be computed from a salary alone.
A worked example
At $100,000, the annual difference between Alberta and Nova Scotia is $5,713. Spread over 26 pay periods that is a change of a few dozen dollars a cheque — real, but rarely the largest line in a decision about where to live.
At $40,000 the difference narrows to $1,643, because payroll premiums are capped amounts rather than percentages and dominate a smaller salary in both regions equally. Read the whole table rather than the row nearest your own salary: the trend across it is what tells you whether the gap will widen as your income grows.
Key terms
- Take-home pay
- Salary less income tax, CPP or QPP and EI. The amount that reaches your account before benefits or retirement deductions.
- Annual gap
- One region’s take-home pay minus the other’s at the same salary. Positive means the first region named leaves you with more.
- Marginal rate
- The combined federal and provincial rate on the next dollar earned. What decides the after-tax value of a raise in each region.
- Payroll premiums
- CPP or QPP, EI and QPIP. Identical in both regions except where Quebec is involved, and capped at an annual maximum.
