Other Tax Measures
Property and Education Mill Rate Adjustment
In keeping with the existing indexing policy, property and education mill rates will increase by the rate of inflation. The Class 4 property tax mill rate will remain unchanged from the 2025–26 level to support the diamond mining sector.
Carbon Tax Increase
Effective April 1, 2026, the Northwest Territories’ carbon tax rate will increase by $15 to $110 per carbon-equivalent ton of greenhouse gas emissions.
Following federal changes announced in March 2025 that eliminated the consumer carbon price[3], the Government of Northwest Territories discontinued the consumer carbon tax on fuels effective April 1, 2025.[4] Diamond mines, which are the sole large emitters in the Northwest Territories, remain subject to the industrial carbon tax with a federally approved rebate system.
