Ontario Employee Payroll Tax Calculator
Ontario Employee Payroll Tax Calculator
Estimate take-home pay for Ontario employees with 2026 CRA payroll formulas, federal and Ontario claim codes, CPP, CPP2, EI, Ontario surtax, Ontario Health Premium, pre-tax deductions, after-tax deductions and year-to-date maximum checks.
Detailed deduction results
| Deduction | What this calculator used | Per pay period | Annualized |
|---|
Annualized results multiply this pay-period estimate by the selected pay frequency. They are best for planning, because true payroll tax can change when CPP, CPP2 or EI maximums are reached midyear.
Ontario payroll rules this calculator watches
The calculator applies the per-period basic exemption, the 2026 CPP maximum, the first additional CPP tax deduction and the CPP2 band above the YMPE.
EI is calculated at 1.63% of insurable earnings until the employee reaches the 2026 maximum annual premium of $1,123.07.
The Ontario Health Premium is part of Ontario tax withholding for payroll purposes, but it is not the same as Ontario Employer Health Tax.
Federal and Ontario claim codes feed non-refundable tax credits. The calculator lets you use claim codes or override the annual TD1 amount directly.
Sources and assumptions
This calculator uses the CRA T4127 122nd edition effective January 1, 2026, the current-year T4127 page, CRA 2026 Ontario payroll deduction guidance, CRA EI maximums and the Ontario personal tax dataset. CRA has also published the July 1, 2026 T4127 update; Ontario values are unchanged in that July table.

Ontario employee payroll calculator FAQ
Does this replace CRA PDOC?
No. It is a planning and review calculator. CRA PDOC, payroll software and the employee's actual TD1 records should be used for final withholding.
Why does net pay change after the CPP or EI maximum?
Once an employee reaches the annual CPP, CPP2 or EI limit with the employer, those deductions stop or reduce, so later cheques can be higher.
Is Ontario Health Premium included?
Yes. The calculator includes the Ontario Health Premium in Ontario tax when annualized income is above the payroll formula threshold.
Can I calculate a bonus?
This calculator is optimized for regular employment pay. CRA has separate bonus and commission methods, so unusual payments should be checked in payroll software or CRA PDOC.
