A bonus is taxed at your marginal rate — like extra salary. We compute tax on (salary + bonus) minus tax on salary, exactly the CRA bonus method.
What your employer withholds
Your employer withholds tax on bonuses with this same marginal method, so the bonus cheque should land close to the number above. Small differences — TD1 claim codes, other income, timing — get settled when you file. (The 10%/20%/30% 'lump-sum rates' you may have heard of are for retiring allowances, not bonuses.)

How does bonus withholding work in Alberta?+
Your employer withholds tax on a bonus with the the CRA bonus method: tax on your total annual income including the bonus, minus tax without it. It matches your final tax bill — not a separate flat rate. The 10%/20%/30% "lump-sum rates" quoted online are for retiring allowances and RRSP withdrawals, not salary bonuses.
Do I pay CPP and EI on my bonus in Alberta?+
Yes — bonuses are pensionable and insurable earnings, up to the yearly maximums ($74,600 for CPP and $68,900 for EI in 2026). On a $75,000 salary with a $5,000 bonus in Alberta, that's $200 CPP and $0 EI on the bonus. Earn over the maximums and no CPP/EI applies.
What is a bonus pay calculator?+
A bonus pay calculator estimates how much of your bonus pay you actually keep after tax. Enter your salary and bonus, pick your province, and it applies the CRA bonus method — tax on (salary + bonus) minus tax on salary alone — to show income tax, CPP/EI, and your take-home from the bonus.
How is a one-time bonus taxed in Canada?+
A one-time bonus is taxed exactly like regular salary: at your marginal income tax rate, plus CPP and EI up to the annual maximums. There is no special flat "bonus tax rate" in Canada — a $10,000 one-time bonus on a $100,000 Alberta salary keeps $6,950 after $3,050 income tax.
