Average vs. marginal tax rate
Your average rate is total tax divided by income. Your marginal rate is the tax on your next dollar — the rate that applies to a raise, bonus or extra income. Canada's system is progressive, so the marginal rate is always higher than the average.
FAQ
Is this my refund or my paycheck deduction?
Neither exactly — this is your total annual income tax. For take-home pay per paycheque (after CPP and EI), use the take-home pay calculator.
