About

Go Home Early Canada is a small set of free calculators for employees: take-home pay after tax, CPP and EI, and the Ontario minimum for notice, termination pay and severance pay. It is an independent project. It is not run by, endorsed by or connected with the Canada Revenue Agency, the Government of Ontario or any other government body.

Why this exists

The operator has handled pay, tax and payroll calculations for a small team firsthand. The calculators available gave different numbers for the same inputs and did not say where the numbers came from, so the figures had to be worked out again from the official formulas. This site publishes that working, with the source and the check date next to each number.

Rates come from the source

Tax brackets, CPP, CPP2 and EI figures and the payroll formulas come from the CRA's T4127 Payroll Deductions Formulas and its published tables. Notice, termination pay and severance pay come from Ontario's Employment Standards Act, 2000 and Ontario Regulation 288/01 on ontario.ca. The Sources and rates page lists each value, where it came from and the date it was last checked.

Checked against official examples

The pay calculations are tested against the worked scenarios in T4127, results from the CRA's Payroll Deductions Online Calculator for every province and territory covered, and an independent second implementation. The Ontario figures are tested against hand calculations from the Act. The site is not released with a failing test.

Updates

The CRA publishes new payroll formulas in January and July, and provincial rates can change in between. When they do, the values and the checked dates are updated together. If you find an error, tell us.
