1 The rates represent calendar-year-end rates unless otherwise indicated.

2 The corporate income tax rates for manufacturers of qualifying zero-emission technology are reduced to 7.5% for eligible income otherwise subject to the 15% general corporate income tax rate or 4.5% for eligible income otherwise subject to the 9% small-business corporate income tax rate.

3 An additional tax applies to banks and life insurers at a rate of 1.5% on taxable income (subject to a $100 million exemption to be shared by group members), effective for taxation years ending after 7 April 2022 (prorated for taxation years straddling this effective date)

$0 to $48,326

$48,327 to $96,655

$96,656 to $157,139

Ordinary income1

Eligible dividends

Non-eligible dividends

$157,140 to $165,430




$165,431 to $235,6752




Above $235,675




1  The rate on capital gains is one-half the ordinary income tax rate.

2 The federal basic personal amount comprises two elements: the base amount ($13,521 for 2023) and an additional amount ($1,479 for 2023). The additional amount is reduced for individuals with net income in excess of $165,430 and is fully eliminated for individuals with net income in excess of $235,675. Consequently, the additional amount is clawed back on net income in excess of $165,430 until the additional tax credit of $222 is eliminated; this results in additional federal income tax (e.g., 0.32% on ordinary income) on net income between $165,431 and $235,675.

Other tax measures

Property tax

In keeping with the existing indexation policy, property mill rates will be adjusted for inflation.

Carbon pricing

The Northwest Territories will be debating increasing its carbon tax in line with the upcoming federally mandated carbon tax rate increase to $65 (from $50) per carbon-equivalent tonne of greenhouse gas emissions. If, on 1 April 2023, the Northwest Territories raises its carbon tax, it will also increase the Northwest Territories cost of living offset amounts.

On the other hand, if the Northwest Territories decides not to raise its carbon tax, the federal backstop system will apply and carbon tax revenues generated in the territory will be distributed through federal programs.
