A resident's territorial tax is worked out on the NU428 and the NU479, attached to the federal return. Residents also get the federal northern residents deduction.
The rules (2026)
Four brackets: 4% up to $55,801, 7% to $111,602, 9% to $181,439 and 11.5% above.[1] Credits are taken at 4%.
- Basic personal amount: $19,659.[2]
- Spouse or eligible dependant: $19,659 less the dependant's net income.[3]
- Age amount: $12,550 at 65 or over, less 15% of net income above $46,432.[4]
- Pension amount: $2,000, the federal amount.[5] CPP and EI are credited as federally.[6]
- Young children: $1,200 a year for each child under 6 at some time in the year; in a couple, the parent with the lower income claims it.[7]
- Dividends: 5.5072% (eligible) and 2.6087% (other) of the grossed-up dividend.[8][9]
- Minimum tax: 45% of the federal additional tax.[10] Foreign tax is credited on the T2036.[11]
There is no surtax, health premium or low-income reduction.
The cost of living tax credit
2% of net income, up to $1,500 once income passes $75,000. A single parent adds 2% of income over $60,000, up to $255.12. Whatever is more than the tax is paid out.[12]
The payroll tax
Every employee pays 2% of their gross pay to the territory, withheld by the employer. It is not an income tax and nothing credits it.[13] The plan counts it with the territorial tax.
After 2026
The brackets and most credit amounts are indexed like the federal ones. The young child amount and the cost of living credit are fixed in dollars:[14] they grow with the plan's rate by default and stay put under the law as written. See tax brackets after 2026.
What it does not do
The volunteer firefighter and search and rescue credit and the payroll tax rules for someone who normally works outside the territory are not modelled. See also Nunavut benefits.
