New Brunswick Income Tax: 2026 Overview

New Brunswick simplified its provincial income-tax structure in 2023, consolidating from five brackets down to four with rates of 9.4%, 14%, 16% and 19.5%. The reform also lowered the entry rate from 9.68% to 9.4% and merged the previous third bracket, making the system more competitive among Atlantic provinces. Residents of Fredericton, Moncton, Saint John and across the province now face a meaningfully lower middle-income tax burden compared with neighbouring Nova Scotia and PEI, although still higher than Ontario and the provinces further west, apart from Manitoba, whose burden is roughly the same.

The basic personal amount (BPA) for 2026 is $13,664, modestly above the Nova Scotia BPA but below Manitoba's, PEI's or Saskatchewan's. New Brunswick's own top rate of 19.5% starts at $193,861; the top combined federal-provincial marginal rate of 52.5% applies once income passes the top federal bracket at $258,482, making it less punitive on top earners than Nova Scotia (54.0%) or Newfoundland and Labrador (54.8%). The province does not levy a provincial surtax or health-care premium on individuals.
