Compares the final annual estimate with and without the bonus. CPP/QPP and EI are incremental annual contributions, not deductions on a specific payday. CRA bonus withholding and Quebec payroll rules can produce a different deposit. Assumes one employer, standard credits and no other deductions. RRSP deductions are capped here at the bonus; you must have sufficient actual deduction room.

Your result is ready

How much of a Canadian bonus do you keep?

This calculator estimates the change in your final annual cash position when a bonus is added to employment income. It calculates the year twice, once without the bonus and once with it, then shows the difference in federal and provincial income tax and payroll contributions.

For example, an Ontario employee with $75,000 in other annual employment income and a $10,000 bonus keeps approximately $6,754 in additional annual cash under the model. The income tax difference is $2,846, with $400 additional CPP and $0 additional EI. Your actual bonus deposit can differ.

Bonus withholding and final tax are different calculations

CRA requires bonuses and irregular employment payments to be reported and payroll deductions to be withheld. Employers use the applicable bonus or irregular-payment method. That is a payroll calculation at the payment date, rather than the final annual comparison shown here.

Year-to-date contribution maxima, prior bonuses and payroll information can change the deposit. CRA’s employer guide explains the bonus method, and its Payroll Deductions Online Calculator supports payroll calculations. Quebec also has provincial deduction rules administered by Revenu Québec. Use those services for an actual payroll run.

CPP, QPP, EI and QPIP on the extra income

The contribution rows show the annual difference between the two scenarios. If annual employment income already reaches a contribution maximum, adding a bonus may cause little or no further contribution for that component. Below a ceiling, some of the extra earnings can attract contributions.

The model assumes one employer and uses the selected province’s annual treatment. Multiple employers can create excess payroll deductions that are handled separately on filing. Do not read a zero incremental annual contribution as a promise that an employer will deduct nothing from the bonus cheque.

Using a bonus for an RRSP contribution

Enter only an additional RRSP contribution that you intend to deduct for the selected year and have room to claim. The calculator caps this amount at the bonus. It shows cash separately from money contributed to the RRSP, so a lower cash figure is not mistaken for lost value.

An RRSP deduction reduces taxable income; it does not automatically remove CPP/QPP, EI or QPIP on the employment bonus. The tax saved can span more than one bracket, so a single marginal-rate multiplication may not match the result. Carry-forwards, other deductions, family credits and changes in benefits are outside this comparison.

Frequently asked questions

Is there a flat final bonus tax rate in Canada?

The final annual tax generally depends on total taxable income and province. Payroll withholding on the payment is a separate calculation and is not necessarily your final tax cost.

Does this show my bonus cheque?

No. It estimates the additional annual cash after final tax, contributions and the entered RRSP deduction. It does not reproduce an employer’s payment-date payroll calculation.
