RRSP calculator New Brunswick: 2026 tax refund
A $10,000 RRSP contribution returns about $2,789 at $60,000 of income and $3,450 at $100,000 in New Brunswick (2026 federal plus provincial tax). Each dollar you deduct saves the combined federal and provincial rate at the income it comes off, so the refund blends the rates across the slice you deduct. Your marginal rate at $60,000 is 34.50% and at $100,000 is 34.50%; a deduction that crosses a bracket edge saves less than the top rate times the amount.

How the New Brunswick RRSP refund works
An RRSP contribution is a deduction, not a credit: it lowers your taxable income, and the tax you save is the federal plus New Brunswick tax on the income you no longer report. In other words the refund is the sum of your combined marginal rates over the slice of income you deduct, so it is at most your contribution times the marginal rate at the top of your income and is lower when the deduction crosses into a cheaper bracket. Enter the income you would otherwise be taxed on and the amount you will claim; the calculator prices the tax with and without the deduction using the 2026 federal and New Brunswick brackets.
New Brunswick has four brackets in 2026: 9.4%, 14%, 16% and 19.5%, with a basic personal amount of $13,664 and the first bracket ending at $52,333.
