Capital Gains Tax in the Northwest Territories
The Northwest Territories stretches across a vast northern landscape, with an economy centered on mining (diamonds, gold, and rare earth minerals), government services, and Indigenous enterprises. Despite the remote geography, NWT residents participate fully in Canada’s investment markets. When you sell an asset for a profit, the capital gain is subject to tax — but only 50% of the gain is included in your taxable income, and it’s taxed at your combined federal and NWT marginal rate.
The NWT has one of the most favourable tax environments in Canada for investors. With a top combined marginal rate of just 47.05%, the maximum effective capital gains tax rate is 23.53% — lower than every province and second only to Nunavut among all Canadian jurisdictions.
Northwest Territories 2026 Tax Brackets
NWT Territorial Tax Brackets (2026)
| Tax Bracket | Rate |
|---|---|
| First $50,597 | 5.90% |
| $50,597 – $101,198 | 8.60% |
| $101,198 – $164,525 | 12.20% |
| Over $164,525 | 14.05% |
The NWT’s four-bracket system features relatively low rates across the board. The top rate of 14.05% is significantly lower than the top rates in provinces like Nova Scotia (21.00%), Newfoundland (21.80%), or Quebec (25.75%).
How the Northwest Territories Compares
The NWT’s top capital gains rate of 23.53% is one of the lowest in all of Canada — lower than every province. Here’s how it compares to its territorial peers and Alberta:
| Jurisdiction | Top Combined Rate | Top CG Rate |
|---|---|---|
| Northwest Territories | 47.05% | 23.53% |
| Nunavut | 44.50% | 22.25% |

Capital Gains Tax Rates in the Northwest Territories
With the 50% inclusion rate, NWT residents face these effective capital gains rates:
| Taxable Income Range | Combined Marginal Rate | Effective Capital Gains Rate |
|---|---|---|
| Up to $50,597 | 20.90% | 10.45% |
| $50,597 – $57,375 | 23.60% | 11.80% |
| $57,375 – $101,198 | 29.10% | 14.55% |
| $101,198 – $114,750 | 32.70% | 16.35% |
| $114,750 – $164,525 | 38.20% | 19.10% |
| $164,525 – $177,882 | 40.05% | 20.03% |
| $177,882 – $253,414 | 43.05% | 21.53% |
| Over $253,414 (top bracket) | 47.05% | 23.53% |
The effective capital gains rate in the NWT never exceeds 23.53%, making it an exceptionally tax-efficient jurisdiction for investment income.
Worked Example: Capital Gains Tax in the Northwest Territories
Scenario: You are a Yellowknife mining engineer earning $140,000 in employment income. You sell mining company shares for a $100,000 capital gain.
Step 1: Calculate the taxable capital gain
| Amount | |
|---|---|
| Total capital gain | $100,000 |
| Inclusion rate | 50% |
| Taxable capital gain | $50,000 |
Step 2: Determine which brackets the gain falls into
Your employment income of $140,000 places you in the NWT’s third bracket and the third federal bracket. The $50,000 taxable gain pushes your total taxable income from $140,000 to $190,000, crossing the NWT’s top bracket at $164,525 and a federal bracket at $177,882.
| Income Range | Amount | Federal Rate | NWT Rate |
|---|---|---|---|
| $140,000 – $164,525 | $24,525 | 26.00% | 12.20% |
| $164,525 – $177,882 | $13,357 | 26.00% | 14.05% |
| $177,882 – $190,000 | $12,118 | 29.00% | 14.05% |
Step 3: Calculate the tax
| Component | Calculation | Tax |
|---|---|---|
| Federal tax | $24,525 × 26% + $13,357 × 26% + $12,118 × 29% | $13,364 |
| NWT tax | $24,525 × 12.20% + $25,475 × 14.05% | $6,571 |
| Total tax on gain | $19,935 | |
| Effective rate on $100,000 gain | 19.94% |
Even with a $100,000 gain on top of a high salary, the effective rate stays under 20%. In Ontario, the same scenario would generate roughly $27,000 in tax thanks to the surtax — a $7,000 difference.
How to Reduce Capital Gains Tax in the Northwest Territories
Claim the Northern Residents Deduction to Lower Your Brackets
All NWT communities fall within Zone A of the Northern Residents Deduction, providing a residency deduction of approximately $11 per day (roughly $4,000 annually) plus a travel deduction for prescribed trips south. This deduction directly reduces your taxable income — and since it’s applied before your capital gain hits the brackets, it effectively pushes the gain into lower rate territory. Ensure you claim the full entitlement every year, even in years without capital gains, to keep your base income as low as possible.
Time Mining Stock Sales Around Commodity Cycles
The NWT economy revolves around mining — diamonds, gold, and rare earths. If you hold shares in mining companies, commodity price cycles create natural windows for tax planning. Selling during a commodity upswing locks in gains, but doing so in a year when your other income is lower (such as between contracts or during a sabbatical) can keep the total in a lower bracket. Conversely, selling during downturns can crystallize losses you bank for later.
RRSP Contributions for High Earners
Mining and government positions in the NWT often pay well above national averages. An RRSP contribution in the same year as a capital gain provides a deduction at your full marginal rate. At the NWT’s combined rate of 38–40% for typical high earners, a $20,000 RRSP contribution can save $7,600–$8,000 in tax while building retirement savings.
Spousal Income Splitting
If one spouse earns significantly more than the other, a spousal RRSP lets the higher earner claim the deduction while the lower-income spouse eventually withdraws at a lower rate. For NWT couples where one partner works in mining and the other doesn’t, this can prevent the mining income plus capital gains from stacking in the higher earner’s brackets.
Northwest Territories–Specific Tax Considerations
One of Canada’s Lowest Tax Jurisdictions
The NWT’s top combined rate of 47.05% is lower than all provinces except Alberta and Saskatchewan (both at 48.00% or lower). For capital gains specifically, the NWT’s 23.53% top rate means territory residents retain more of their investment profits than almost anywhere else in Canada.
Northern Residents Deduction
NWT residents qualify for the Northern Residents Deduction, which provides a daily residency deduction (approximately $11 per day for Zone A, which covers all of the NWT) plus a travel deduction. While this doesn’t directly reduce capital gains tax, it lowers overall taxable income, which can keep capital gains in lower brackets.
Cost of Northern Living Allowance
Many NWT employers provide a Northern Living Allowance or isolation pay, which is taxable. This additional income means that NWT workers may already be in a higher bracket before capital gains are added, making the bracket thresholds more relevant for tax planning.
Mining and Resource Economy
The NWT is home to Canada’s diamond mines (Ekati, Diavik, Gahcho Kué) and significant gold and rare earth mineral deposits. Many residents work directly or indirectly in the mining sector, and some hold shares in mining companies as part of employee benefit plans. The boom-and-bust cycle of mining creates large gains and losses that should be managed strategically.
Indigenous Investment and Settlement Trusts
Many NWT residents are Indigenous peoples who may receive distributions from land claim settlement trusts or Indigenous development corporations. The tax treatment of these distributions varies and may include a capital gains component. Consultation with a tax professional familiar with Indigenous taxation is recommended.
