A bonus paid for work in New Brunswick is employment income. Enter your salary and bonus to see the estimated incremental tax and payroll contributions — not a flat bonus tax rate.
What your employer may withhold
Payroll software may treat a bonus as a lump-sum or extra-period payment. The amount withheld on the cheque can be higher or lower than this annual estimate. The year-end T4 / Relevé 1 is what matters for your actual tax.
Frequently asked questions
Is a bonus taxed differently in New Brunswick than regular salary?
For annual tax, no — it is employment income. Withholding on the bonus payment itself can still look different from regular paycheques.
How is the net bonus calculated?
Net bonus is estimated take-home on salary plus bonus minus estimated take-home on salary alone.
Will I pay more CPP or EI on a bonus?
Only if you have not already reached the annual maximums. High earners who have already maxed CPP/QPP and EI should see mostly income tax on the extra amount. Quebec also uses QPIP.
Why doesn’t this match my bonus cheque?
Employers withhold using payroll formulas that can differ from the final annual tax on the combined income. This page estimates the annual incremental effect.
