To save tax on a bonus in Canada, directly contribute it to an RRSP to deduct it from taxable income, use a FHSA for tax-free growth, or request a direct transfer from your employer to avoid immediate withholding tax. Bonuses are taxed as regular income but often have higher initial withholding rates, requiring deductions to be claimed at year-end.
Bonuses are considered “supplemental income,” which simply means money you earn over and above your regular paycheque. In Canada, this supplemental income is subject to income tax, just like your regular salary. In other words, your regular salary and your bonus are subject to the exact same amount and type of tax.
You can't entirely avoid taxes on a bonus, but you can significantly lower the amount by contributing to tax-advantaged accounts (401(k), IRA, HSA), deferring the bonus to a year you expect to be in a lower tax bracket, or making charitable donations, thereby reducing your taxable income or increasing deductions at tax time.
Basic Tax Treatment
The source deduction includes federal and provincial income tax, Canada Pension Plan (CPP) contributions, and Employment Insurance (EI) premiums. The bonus is added to your total annual income and taxed according to Canada's progressive tax system, where higher income levels have higher tax rates.
The benefits of bonus sacrifice
The main benefit of paying your bonus into your pension is tax relief. If you take your bonus as cash, this will be subject to income tax, National Insurance contributions and maybe other deductions (such as student loans).

The IRS allows two primary methods for taxing bonuses. The percentage method uses a flat 22% federal tax rate. This method is straightforward but could result in over-withholding for some individuals. The aggregate method combines your bonus with your regular earnings and then calculates taxes based on the total.
One of the most notable differences between bonuses and raises is the duration of the compensation. Bonuses are one-time, short-term financial rewards. A raise is an increase to your current salary for the foreseeable future and provides more long-term benefits.
The taxes on bonuses are the same as if they were included in your basic salary. In Canada, bonuses are considered a taxable benefit and therefore are considered taxable income. The tax rates, however, will vary depending on your Province or Territory.
