Capital Gains Tax in New Brunswick
New Brunswick, one of Canada’s three Maritime provinces, has a growing investment community. Affordable real estate, a lower cost of living, and increasing remote work opportunities have attracted new residents and investors to the province. When you sell a capital asset for a profit, the resulting capital gain is subject to tax — but only 50% of the gain is included in your taxable income. That taxable portion is taxed at your combined federal and New Brunswick marginal rate.
New Brunswick’s top combined marginal rate of 52.50% places it in the upper-middle range nationally. The maximum effective capital gains tax rate is 26.25%, which is higher than western provinces but lower than Ontario, BC, or Quebec.

Worked Example: Capital Gains Tax in New Brunswick
Scenario: You are a Moncton-based remote worker earning $110,000 in employment income. You sell a diversified stock portfolio for a $45,000 capital gain.
Step 1: Calculate the taxable capital gain
| Amount | |
|---|---|
| Total capital gain | $45,000 |
| Inclusion rate | 50% |
| Taxable capital gain | $22,500 |
Step 2: Determine which brackets the gain falls into
Your employment income of $110,000 already sits in New Brunswick’s third bracket and the second federal bracket. The $22,500 taxable gain pushes your total taxable income from $110,000 to $132,500, crossing a federal bracket boundary at $114,750.
| Income Range | Amount | Federal Rate | NB Rate |
|---|---|---|---|
| $110,000 – $114,750 | $4,750 | 20.50% | 16.00% |
| $114,750 – $132,500 | $17,750 | 26.00% | 16.00% |
Step 3: Calculate the tax
| Component | Calculation | Tax |
|---|---|---|
| Federal tax | $4,750 × 20.50% + $17,750 × 26% | $5,589 |
| NB tax | $22,500 × 16.00% | $3,600 |
| Total tax on gain | $9,189 | |
| Effective rate on $45,000 gain | 20.42% |
The entire taxable gain falls within NB’s 16% third bracket, keeping the provincial portion predictable. The federal rate jump at $114,750 is the main driver of the combined effective rate.
How to Reduce Capital Gains Tax in New Brunswick
Tax-Loss Harvesting to Offset Gains
When you realize a capital gain from selling a stock portfolio or investment property, check whether any other holdings are sitting at a loss. Selling those losing positions crystallizes a capital loss that offsets your gain dollar-for-dollar on the taxable portion. With NB’s top capital gains rate at 26.25%, each dollar of harvested loss saves over 26 cents at the margin, and unused losses can be carried forward indefinitely.
RRSP Contributions for Maximum Deduction Value
New Brunswick’s steep bracket jump from 9.40% to 14.00% at $51,306 — and again to 16.00% at $102,614 — means RRSP deductions deliver strong value. A contribution made in the same year as a capital gain pulls taxable income down, potentially dropping you back below a bracket boundary. For NB residents in the third or fourth bracket, the combined federal-provincial deduction value exceeds 42 cents per dollar contributed.
Consider Relocation Timing for Interprovincial Moves
New Brunswick has attracted many remote workers from Ontario and other higher-cost provinces. If you’re planning an interprovincial move, timing matters: the province of residence on December 31 determines where your entire year’s income is taxed. Moving to NB before year-end and realizing gains as an NB resident may or may not save you tax compared to your previous province — run the numbers both ways, since NB’s rate of 26.25% is lower than Ontario’s 26.77% but higher than Alberta’s 24.00%.
Principal Residence Exemption
New Brunswick real estate has appreciated significantly since 2020 as Canadians migrate east for affordability. If you sell the home you ordinarily inhabit, the entire gain is exempt from tax — no matter how large the appreciation. Properties purchased in Moncton, Fredericton, or Saint John before the recent price surge could have substantial embedded gains that the exemption protects completely.
New Brunswick–Specific Tax Considerations
Atlantic Canada Growth and Capital Gains
New Brunswick has benefited from the post-pandemic migration trend, with many Canadians relocating from Ontario and other expensive provinces for more affordable housing and a better cost of living. This has driven real estate appreciation in cities like Moncton, Fredericton, and Saint John. Investment property owners who bought before this trend may be sitting on significant capital gains.
New Brunswick Tax Reduction
New Brunswick offers a provincial tax reduction for lower-income residents that effectively reduces the tax payable. A large capital gain in a single year could reduce or eliminate eligibility for this benefit, creating an additional reason to manage the timing of gain realization.
Small Business Investment
New Brunswick’s small business tax rate is among the lower rates in Canada. Business owners who hold investments within a corporation should consider the integration of corporate and personal tax, as withdrawing corporate investment gains may result in different effective rates than selling personally.
Harmonized Sales Tax (HST)
New Brunswick charges a 15% HST (5% federal + 10% provincial). While this doesn’t affect capital gains tax, it’s among the highest combined sales tax rates in Canada and is relevant to overall after-tax financial planning.
New Brunswick Workers’ Benefit
New Brunswick provides an income-tested workers’ benefit. Significant capital gains in a year could affect eligibility for this and other income-tested provincial credits.
