What it does
The NWT Income Tax Calculator estimates the combined federal and Northwest Territories personal income tax on a year of income, the income left after tax, the average and marginal rates that apply, and how the territorial bill compares with a province on the same income.

The formula
Total tax = (federal brackets on taxable income − federal BPA × lowest federal rate) + (NWT brackets on taxable income − NWT BPA × lowest NWT rate)
How it works
It subtracts any RRSP contribution and other deductions to reach taxable income, runs the federal bracket table and the Northwest Territories bracket table over that figure, and subtracts each jurisdiction's basic personal amount as a non-refundable credit at its lowest rate. The comparison repeats the provincial half of that calculation for the jurisdiction you pick.
Where it is used
- Estimating income tax on a Northwest Territories salary or self-employed profit
- Seeing what a move to or from the territory does to the tax bill
- Checking the combined marginal rate before taking on extra work or claiming the northern residents deduction
Worked example
On CA$95,000.00 of Northwest Territories income with no deductions, federal tax is … and territorial tax is …, a combined bill of … that leaves … — an average rate of … and a combined marginal rate of …. Alberta would charge … of provincial tax on the same income, so on brackets alone the territory is the cheaper of the two here by …, where a positive figure means NWT charges less. The territorial basic personal amount is already netted off as … of credit, and there is no NWT surtax or health premium to add. A northern residents deduction would go in the other deductions field, which lowers both halves of the bill.
What the NWT income tax calculator does
The calculator estimates the federal and Northwest Territories tax on a year of income and what is left afterwards. Enter an income and any deductions, and the tool runs both bracket tables, applies both basic personal amounts as non-refundable credits, and reports the total bill, the average rate and the marginal rate on your next dollar.
Ottawa runs one bracket table for everyone, and each province and territory runs its own second table; where you live on 31 December decides which. General Canadian calculators often default to Ontario or a national average, which leaves NWT filers doing their own arithmetic.
How the territorial brackets work
- 5.9% up to $53,003
- 8.6% to $106,009
- 12.2% to $172,346
- 14.05% above that
The 5.9% entry rate is one of the lowest in Canada, and the 14.05% top rate is well below what Ontario, Quebec, Nova Scotia or Newfoundland and Labrador charge at the top of their scales.
The bands are wide, so much of a normal working income sits inside one territorial rate and a raise does not push you over a threshold as quickly as further south. There is also no territorial surtax or health premium. Ontario’s surtax lifts its effective top provincial rate by more than half again, and its health premium adds up to $900 a year. The territorial figure this tool produces is the whole territorial figure.
Brackets, thresholds and personal amounts are maintained parameters, so the tool follows the yearly indexation of the federal and territorial tables.
A worked example
On $95,000 the federal tax is about $13,368 and the territorial tax about $5,665, a total of $19,033 and an average rate of about 20%. The marginal rate is 29.1%: 20.5% federal plus 8.6% territorial. On the same income Alberta’s provincial tax would be about $6,454, so the NWT charges about $789 less.
The two basic personal amounts
Both governments give you an effectively untaxed amount of income as a credit: the calculator multiplies each basic personal amount by that jurisdiction’s lowest rate and subtracts the result from tax. A credit is worth the same to a high earner as to a low earner, unlike a deduction, which is worth more at a higher marginal rate.
The NWT basic personal amount, $18,198, is generous compared with most provinces and is worth about $1,074, so territorial tax on a modest income is small. The federal amount is larger, worth about $2,303 in the example.
Deductions and the northern residents deduction
An RRSP contribution and anything in the other deductions field come off income before either bracket table applies.
The other deductions field is where the northern residents deduction belongs. The whole territory is in Zone A, the higher of the two prescribed zones, so both the residency and travel parts are claimable in full if you meet the six-month residency test. Because it reduces the income both governments tax, each dollar claimed is worth your combined marginal rate, about 29 cents at $95,000.
Comparing with a province
The comparison runs the provincial part of the calculation for another jurisdiction on the same taxable income: bracket tax less the basic personal amount credit. It excludes surtaxes, health premiums and sales taxes.
Against Alberta the NWT usually looks competitive on brackets at middle incomes. Against Ontario the bracket comparison is closer than people expect, and the Ontario figure is before its surtax and health premium, which push the real bill higher. None of these tables capture the cost of living in the north, which usually decides the question.
Average rate and marginal rate
The average rate is the whole bill divided by gross income and tells you what the year cost. The marginal rate is the tax on the next dollar, federal plus territorial, and tells you what an extra shift, a bonus, a side contract or an RRSP contribution is worth. On a progressive schedule it is always the higher of the two.
Because the second territorial band is wide, many NWT filers face the same combined marginal rate over a long stretch of income, so the tax on overtime stays fairly stable through much of a career.
All figures are an estimate from the published bracket tables and basic personal amounts, before payroll contributions, refundable credits and personal circumstances on your return. This is not tax advice; check your assessment or speak to an accountant before acting on it.
