Our Mission
Our goal is to help users across Canada quickly and accurately calculate Goods and Services Tax (GST), Harmonized Sales Tax (HST), and Provincial Sales Tax (PST) — whether you need to add tax to a subtotal or reverse-calculate the pre-tax amount from a total. We built these tools to make tax math fast and effortless.

Independence & Transparency
We are not affiliated with the Canada Revenue Agency (CRA) or the Government of Canada. Our calculators are independent tools designed for informational purposes only and should not replace professional tax advice.
