Plain-language terms for using CanadianTaxes.ai. By using the site, you agree to them.
What we are, and what we are not
CanadianTaxes.ai is an independent information service. We are not the Canada Revenue Agency, not a government site, and not a law or accounting firm. Our answers, calculators and SmartFiles give general information about Canadian tax rules. They are not professional advice about your situation, and using them does not make us your accountant or lawyer.
CanadianTaxes.ai is operated by 2121724 Ontario Inc., Ontario, Canada. GST/HST registration number: 852252188 RT0001.
You stay in charge of your return
You decide what goes on your tax return, form or objection, and you are responsible for it. Check every number and every word before you sign or send anything. CRA makes the final decision on every return and every claim.
Our numbers have limits
We work hard to get the rules right: every rate has a source, and every calculator is tested. Even so, rules change, situations differ, and estimates are estimates. Each result lists what it assumed and what it left out. When we say a situation needs a professional, please take that seriously.
The AI assistant
The assistant explains rules in plain English and uses our calculators for numbers. It can still be wrong or incomplete. Do not rely on it alone for a decision that matters, and do not type in your social insurance number, account numbers or passwords.
SmartFiles and paid checks
- A SmartFile or check is for one tax situation for one person or household (one return, one letter, one objection, one sale, one business registration). A Return Check bought with the spouse option covers two returns.
- Each check includes a set number of runs, shown in your workspace. The Tax Year Pass and the Rental Property File last 12 months from purchase and do not renew.
- Our Return Check promise: if CRA changes your return because of an item on our published checklist that we should have caught from the documents you gave us, we refund the fee for that check. We do not pay taxes, interest or penalties.
- Your private link is your access. Keep it to yourself; anyone with the link can open the workspace.
- Your answers are saved in your browser. Use “Download backup” if you switch computers or clear your browser.
- Filled CRA forms are created on your own computer from the official forms on canada.ca. If CRA changes a form, we update SmartFile as soon as we can.
Prices and refunds
Prices are in Canadian dollars, plus GST/HST at your province's rate. If a SmartFile or check does not fit your situation, or does not work as described, tell us within 30 days of buying it and we will refund you in full. Refund Finder also refunds its fee when it finds less than $100.
Fair use
Please do not overload the site, scrape it, resell our content or SmartFiles, or use the assistant for anything unlawful, including hiding income or misleading CRA. We may limit or block use that breaks these terms.
Liability
To the extent the law allows, our total responsibility for any claim about the site, a SmartFile or a check is limited to what you paid us for it. We are not responsible for taxes, interest or penalties that CRA assesses, since those come from your own return and CRA's decisions. Nothing here takes away rights you have under consumer protection law.
Changes, and the law that applies
We may update these terms; the date below shows the latest version. These terms are governed by the laws of Ontario and of Canada.
