Tax Calculator New Brunswick

New Brunswick's top provincial marginal rate is 19.50%. Combined with the 33% federal top rate, top earners face roughly 52.5% on income above $253k. New Brunswick has 4 brackets. Top combined federal + NB rate is 52.5%. NB used to have higher rates but reformed in 2023 to flatten the curve.

In Canada, federal and provincial taxes are calculated separately and stacked on the same income. Most provinces (except Quebec) have the CRA collect both via a single return. Your tax slip shows federal + provincial deductions, and CRA distributes provincial revenue back to your home province.

The Basic Personal Amount (BPA) is a non-refundable tax credit that effectively makes the first portion of your income tax-free. The federal BPA in 2026 is ~$15,705 (reduced for very high earners). New Brunswick's provincial BPA is $13,500. Combined, most New Brunswick residents pay no tax on the first ~$25–30k of income.

RRSP contributions reduce both federal AND New Brunswick provincial income tax — which makes them more valuable in higher-tax provinces. A $10,000 RRSP contribution saves roughly 4,000 (at 41% marginal in New Brunswick) — meaningful in mid-tax provinces. Use our Retirement Calculator to project the long-term impact.

You file as a resident of whichever province you were resident in on December 31 of that tax year. All income for the year is taxed at that province's rate, even income earned elsewhere. Quebec is the major exception with its own rules. Moving in late December to a low-tax province (like Alberta) can yield significant savings, but be aware of residency tests and provincial credits.

Yes — New Brunswick has 4 progressive brackets ranging from 9.40% to 19.50%. Each dollar earned is only taxed at the rate for its bracket, not at a single overall rate — see the bracket table above for details.
