# Terms of use

> The terms for using Tax Calculator Canada and its ChatGPT and Claude connector: free estimates from published rates, not tax, legal or financial advice.

Canonical: https://taxcalculatorcanada.ca/terms

Tax Calculator Canada is free to use, on this site and through our connector for ChatGPT and Claude (/chatgpt). By using it you accept these terms.

The calculators give estimates from the 2026 rates and rules published by the Canada Revenue Agency, Revenu Québec, Retraite Québec, Ontario and each province and territory. Each page and each connector answer says what it assumes. They are not tax, legal, accounting or financial advice, they do not know your full situation, and they are no substitute for your own return, your pay stub, an official assessment or a qualified professional.

We check the figures against the official sources and fix mistakes as soon as we know about them, but we can't promise every figure is complete, current or right for you. You use the results at your own risk; to the extent the law allows, we are not liable for any loss from relying on them.

Don't use the site or the connector in a way that harms them or other people, such as automated traffic heavy enough to slow them down; the connector has rate limits for this reason.

This site is not affiliated with the Government of Canada or any province. We may change these terms; the version on this page is the one that applies. Questions: hello@taxcalculatorcanada.ca.
