Who We Are
ReverseSalesTaxCalculator.net is a free online tool built to help Canadians quickly and accurately calculate sales taxes across all provinces and territories. Whether you're a small business owner, accountant, freelancer, or everyday consumer, our calculators are designed to save you time and reduce errors.
We built this tool because we found existing Canadian tax calculators were either too complex, outdated, or didn't properly handle all provincial tax types including GST, HST, PST, and Quebec's unique QST system.
Canada-Focused
Built specifically for Canadian tax rules across all 13 provinces and territories.
Always Updated
Tax rates updated promptly when provinces change rates, like Nova Scotia's 2025 reduction.
Always Free
No registration, no subscription, no hidden fees. Free forever for all users.
Privacy First
All calculations happen in your browser. We never store your financial data.

Our Data Sources
All tax rates are sourced directly from official government publications including the Canada Revenue Agency (CRA), Revenu Québec, and provincial finance ministries. We verify rates regularly and update promptly when changes are announced.
Our Commitment
We are committed to providing accurate, up-to-date, and easy-to-use tax tools. While we strive for accuracy, we always recommend verifying critical figures with the CRA or a qualified tax professional for official filing purposes.
This tool is for informational and estimation purposes. For questions about your specific tax situation, please consult the CRA or a licensed accountant.
