Free Ontario Payroll Calculator

Calculating Ontario payroll taxes can be complex, but our free payroll calculator simplifies the process. Whether you're an employer, HR professional, or small business owner, this tool helps you determine payroll deductions, net pay, and compliance with Ontario's employment standards.

How the Ontario Payroll Calculator Works

The Ontario payroll calculator computes key payroll components based on gross wages and applicable rates. It calculates:

Employment Insurance (EI) premiums
Canada Pension Plan (CPP) contributions
Income Tax deductions
Net pay after deductions

The calculator uses current Ontario tax rates and employment standards. For precise calculations, you may need to adjust for specific employee circumstances or additional benefits.

Net Pay = Gross Wages - (EI Premiums + CPP Contributions + Income Tax)

Note: This calculator provides estimates. For exact payroll processing, consult a professional payroll service or accountant.
