New Brunswick Marginal Tax Rate (2025)

How to read the combined brackets

Canada taxes income progressively at two levels — federal and New Brunswick provincial. Each band below shows the federal rate, the provincial rate, and the combined marginal rate that applies to income in that range. Only the dollars inside a band are taxed at that band’s rate, so crossing into a higher band never raises the tax on your earlier income.

Worked example

Take $80,000 of taxable income in New Brunswick for 2025: it falls in the $57,375–$102,614 band, where the combined federal + provincial marginal rate is 34.50% (20.50% federal + 14.00% New Brunswick). That rate applies only to the dollars inside this band — every dollar below it was taxed at the lower rates shown higher up the table.

What’s distinctive about New Brunswick

New Brunswick sits in the middle on both counts — a moderate number of brackets and a basic personal amount close to the federal figure. That makes the federal thresholds and the OAS clawback the dominant constraints on a New Brunswick retiree's withdrawal planning rather than the provincial ladder, since the provincial steps tend to fall between rather than at the points where the federal rate changes.

Structurally, New Brunswick runs 4 provincial brackets for 2025, from 9.40% up to 19.50%. Laid over the federal brackets, that produces 8 distinct combined bands — meaning a New Brunswick retiree crossing from the bottom of the table to the top passes through 7 separate rate increases, starting at 23.90% and finishing at 52.50% once taxable income passes $253,414.

The New Brunswick basic personal amount is $13,396 against a federal amount of $16,129 — $2,733 less than the federal figure, so provincial tax begins at a lower income than federal tax does. For a retiree with modest income this is often the single most important number on the page: it sets how much RRIF or pension income you can take before the provincial rate applies to any of it.

Why this matters for retirement

When you take money from a RRIF, LIF, or RRSP, it’s taxed at your marginal rate. Knowing where the next threshold sits helps you decide how much to withdraw in a given year — the next-bracket calculator works this out for your exact income, and the retirement planner applies New Brunswick rates across every year of a projection rather than just one.

One caution about reading any bracket table: the combined rates below exclude the OAS recovery tax, which adds an effective 15 percentage points above its threshold, and the roughly 50% reduction rate on GIS for lower-income retirees. Both are invisible here and both can exceed the rate step from crossing a bracket, so check them before concluding that a withdrawal is cheap.
