Retiring in the Northwest Territories: territorial tax and senior programs

Territorial tax brackets for 2026

For 2026, the Northwest Territories charges 5.9% on taxable income up to $53,003, 8.6% up to $106,009, 12.2% up to $172,346 and 14.05% above that. The 2026 territorial basic personal amount is $18,198.

Territorial tax applies to the same taxable income as federal tax, so CPP, OAS, pension income and RRIF withdrawals all count. The bracket table and worked example on this page are calculated from these 2026 figures.

How this affects retirement income

With low territorial rates, the federal brackets usually drive most of the change in a retiree's combined marginal rate. The 2026 federal rate moves from 14% to 20.5% above $58,523, and OAS recovery tax applies at 15% of net income above $95,323 in 2026.

The retirement tax calculator shows combined federal and territorial tax at any income. If you are weighing when to start CPP or OAS, the CPP start-age tool and deferring OAS to 70 walk through the trade-offs.

Territorial programs for older residents

The NWT Senior Citizen Supplementary Benefit is a monthly payment for low-income seniors who receive OAS and GIS, or the Spouse's Allowance. Eligible seniors are considered automatically once the federal benefits are in place, so the GIS application is the important step. See our GIS guide.

The Senior Home Heating Subsidy helps residents aged 60 or older with modest incomes cover part of their heating costs. Extended Health Benefits provide no-cost coverage for residents 60 or older for drugs, dental care, vision care, medical supplies and equipment, and medical travel, as a payer of last resort after other plans.

Income security programs are delivered through regional Education, Culture and Employment service centres, which can help with applications and the documents each program asks for.

What the tax estimate includes

The worked example on this page uses the 2026 federal and territorial brackets and both basic personal amounts. It leaves out the age amount, the pension income amount, dividend and capital gains treatment and other credits, so for many retirees actual tax is somewhat lower than shown. Northern residents deductions are not included either.

Use the figures to compare scenarios rather than to predict a filed return. Dated official figures are gathered on key figures, and the methodology page explains the assumptions.

What to check locally

• That you have applied for GIS if your income is low, since the Supplementary Benefit follows from it.
• Whether the heating subsidy's current income limits for your community zone fit your household.
• Whether you have registered for Extended Health Benefits for seniors, and how any employer plan coordinates with it.
• Whether the northern residents deductions apply to you.
• Any territorial budget changes to brackets or credits.
