How payroll deductions are calculated
- Annualise the pay. Gross pay per period × pay periods per year (52, 26, 24 or 12), minus any RRSP or pension deducted at source.
- CPP: 5.95% of pensionable earnings above the $3,500 basic exemption (prorated per period), up to $74,600. CPP2: 4% between $74,600 and $85,000. In Quebec, QPP is 6.30%.
- EI: 1.63% of insurable earnings up to $68,900 (1.30% in Quebec), plus QPIP at 0.43% in Quebec.
- Federal tax: brackets from 14% to 33%, minus credits at 14% for the basic personal amount, base CPP, EI and the Canada employment amount. The enhanced part of CPP is deducted from income instead.
- Provincial tax: the province’s brackets and credits, plus Ontario’s surtax and health premium or BC’s tax reduction where relevant.
- Divide by the number of pays to get the deduction on each paycheque.
Worked example: $2,500 every two weeks in Ontario
$2,500 bi-weekly ($65,000 a year), Ontario, 2026, claim code 1
Over a year that is $65,000 of income. Each pay loses about $374.06 in income tax, $140.74 in CPP and $40.75 in EI, leaving $1,944.45.

Tips for employees
- Fill in a TD1 if you have credits beyond the basic amount (dependants, tuition, disability): it lowers the tax withheld.
- Ask for reduced withholding with form T1213 if you make regular RRSP contributions or have large deductible expenses.
- Two jobs? Only one employer should give you the basic personal amount; otherwise expect a balance owing.
