Self-Employed Tax Estimator

Estimate what you'll owe in income tax and CPP (or QPP in Quebec) on your self-employment income for the year. Enter your net self-employment income and any other income already taxed at source, and this tool combines federal tax, your province's tax, and CPP/QPP contributions into a single estimate — the same combination the CRA taxes self-employed Canadians on, since there's no separate "self-employment tax" in Canada. If your estimated net tax owing comes out above $3,000 ($1,800 in Quebec), you may need to pay quarterly instalments during the year rather than a single amount at tax time. This estimate is meant to help you plan and set money aside — it doesn't replace an actual tax return or professional advice.

This tool provides estimates only and is not a substitute for professional advice — see our Terms of Service for details.
