New Brunswick taxes income in 4 provincial brackets (9.4%, 14%, 16%, 19.5%), with the top rate starting above $193,861. Combined with federal tax, the top marginal rate is 52.5% on taxable income over $258,482.

New Brunswick's basic personal amount is $13,664. The largest single step in the schedule is at $52,333, where the rate rises from 9.4% to 14%. Crossing that threshold is where the value of an RRSP deduction changes most.

At $70,000 of taxable income, a $5,000 deduction saves $1,725 in New Brunswick, which ranks 5 of 13 provinces and territories. The same deduction saves $1,858 in Nova Scotia and $1,375 in Nunavut.

What an RRSP deduction saves in New Brunswick at each income

2026 federal plus provincial income tax, before and after the deduction. Taxable income is before the RRSP deduction.

$250,000$90,89436.4%48.79%$2,440$4,879

The saving on $10,000 is rarely exactly double the saving on $5,000, because the second $5,000 comes off income that is taxed at whatever rate applies lower down. Usually that rate is lower, so each extra dollar is worth a little less. The biggest step up in value per dollar comes between $100,000 and $125,000, where the saving on $5,000 rises from 34.5% to 42% of the amount deducted.

RRSP refund estimator

Compares 2026 annual tax before and after your RRSP deduction, including bracket crossings, basic personal amounts, Ontario surtax and health premium, BC and Ontario tax reductions, and the Quebec abatement.

Use income after other deductions. Claim no more than your CRA RRSP deduction limit. The model assumes net income equals taxable income before this deduction. Savings reduce tax owing; your cash refund also depends on tax already withheld.

Deduction limit and other credits

Credit reductions are dollars of tax, not claim amounts, and stay fixed in both scenarios. In employment mode the CPP/QPP, EI, QPIP and Canada employment amount credits are already included, so enter only other credits here.

Where the rate jumps in New Brunswick

A deduction is worth the most when it pulls income back below a point where the combined rate rises sharply. Between $25,000 and $260,000, the largest increases in New Brunswick are:

  • $52,333: from 23.4% to 28%, because a new provincial bracket starts.
  • $58,523: from 28% to 34.5%, because a new federal bracket starts.
  • $117,045: from 36.5% to 42%, because a new federal bracket starts.

If your taxable income is a few thousand dollars above $117,045, for example, the first dollars you deduct are saved at 42%, and only the part of the deduction that takes you below $117,045 is saved at the lower 36.5%.

How these numbers are calculated

Each saving is the difference between two full 2026 tax calculations for a single filer with no dependants, before and after the deduction, using the federal and New Brunswick basic personal amounts. It is a change in tax owed; whether you see it as a refund depends on tax withheld during the year. For what the estimate leaves out and how the deadline and limit work, see RRSP savings by province and the RRSP explained.
