Northwest Territories Income Tax Calculator 2026

The Northwest Territories uses four territorial income tax brackets in 2026: 5.90% on the first $51,609, 8.60% from $51,609 to $103,222, 12.20% from $103,222 to $167,816, and 14.05% on income above $167,816. The territorial basic personal amount is $16,925 — one of the most generous in Canada.

The NWT's top territorial rate of 14.05% is the third lowest in Canada after Nunavut and Yukon. Combined with the 33% federal top rate, the combined top marginal rate for NWT residents is approximately 47.1%. For workers in the $75,000–$140,000 range — common for government, natural resource, and construction workers in the territory — the combined marginal rate is typically 36–42%.

The Northwest Territories does not levy a territorial sales tax, and the relatively low territorial income tax rates are part of the broader compensation for the high cost of living in the territory. The high basic personal amount of $16,925 means residents pay no territorial income tax on approximately the first $16,925 of income, reducing the burden on lower-income and part-time workers.
