Bonus Tax in New Brunswick: How It Works
New Brunswick has reformed its tax brackets in recent years, reducing the number of brackets and lowering top rates. The province now has four brackets with a top rate of 19.5%, producing a combined federal-provincial top marginal rate of approximately 52.5%. Bonuses in New Brunswick are treated as ordinary income for tax purposes.
New Brunswick's 2026 provincial brackets are 9.4% (up to $49,958), 14% ($49,958–$99,916), 16% ($99,916–$185,064), and 19.5% above $185,064. A middle-income earner in NB receiving a typical bonus will pay 14% to 16% provincial tax on the bonus portion. Combined with federal tax, effective withholding ranges from 28% to 45% depending on total income.

New Brunswick Bonus Tax: Specific Considerations
New Brunswick's four brackets produce moderate bonus tax for typical earners. A $5,000 bonus on $80K in Fredericton, Moncton, or Saint John is taxed at 20.5% federal + 14% NB = 34.5%, netting roughly $3,275. A $10,000 bonus on $80K nets approximately $6,550. At $25K bonus on $80K, parts cross into the 16% NB bracket (above $99,916), producing effective withholding around 37–39% and net bonus near $15,250–$15,500. New Brunswick's reformed structure (down from five brackets) makes calculations simpler than NL or NS.
New Brunswickers should note that the province offers a New Brunswick Low-Income Seniors Benefit and the NB Child Tax Benefit, but neither affects bonus withholding. The NB Tuition Tax Cashback program was discontinued. RRSP contributions remain the primary in-year lever — particularly for healthcare professionals and government workers in Fredericton receiving retention bonuses. The NB Volunteer Firefighters/Search and Rescue Tax Credit provides a $3,000 deduction at filing time but does not reduce payroll withholding.
Bonus Tax Planning in New Brunswick
New Brunswick residents can use bonuses to fund RRSPs, FHSAs, and TFSAs to optimize tax timing. The province offers a number of refundable and non-refundable credits including the New Brunswick Low-Income Tax Reduction and the Seniors Benefit, but these affect tax owing at filing rather than payroll withholding from bonuses.
The CRA bonus method approximates your marginal tax rate by calculating tax on (annual salary + bonus) and subtracting tax on the salary alone. For New Brunswick residents, this means the withholding closely tracks your true marginal rate — usually within a few percentage points. If you receive your bonus near the end of the year and have already maxed out CPP and EI contributions, your effective withholding rate may be noticeably lower than mid-year bonuses for the same gross amount. RRSP contributions, FHSA contributions, and (in some cases) charitable donations can reduce tax withheld at source if you file CRA Form T1213 (Request to Reduce Tax Deductions at Source) in advance.
