Capital Gains Tax in New Brunswick (2026)

In New Brunswick, half of a capital gain is added to your taxable income, so the rate on the gain is half of your combined federal and provincial marginal rate: 11.70% on lower incomes, up to 26.25% on taxable income over $258,482. What you actually pay depends on how much other income you have, because a large gain can push part of itself into higher brackets.

Is the capital gains inclusion rate different in New Brunswick?

No. The 50% inclusion rate is federal and applies in every province. Only the provincial income tax brackets differ, which is why the rate on a gain differs between provinces. The proposed increase to two-thirds was cancelled in March 2025.

Do I pay capital gains tax on my home in New Brunswick?

Usually not on your principal residence, if you designate it correctly. Rental properties, cottages and second homes are generally taxable, and a gain on shares or funds in a non-registered account is taxable in the year you sell.

Educational estimates, not tax, legal or investment advice. Credits, the alternative minimum tax and the lifetime capital gains exemption are not included. Talk to a licensed Canadian CPA or CFP before acting.
