Canada sales tax calculator
Pick a province or territory, enter an amount, and see the GST, HST, QST or PST worked out. It runs in your browser: nothing you type is sent anywhere.
Rates are dated 2026-10-08 and come from the CRA and provincial finance sites listed on the rates table. Rounded to the cent. Check the CRA or your provincial tax authority before you rely on a figure. This is a calculator, not tax advice. It does not cover zero-rated or exempt goods, the small-supplier threshold, place-of-supply rules or input tax credits.
Need this inside your own spreadsheet?
The Google Sheets add-on puts the same rates, a calculator and quarterly or annual return worksheets (with input tax credits worked out by formula) into your own spreadsheet. It is not in the Google Workspace Marketplace yet. Leave your email and we will write once when it is listed. One confirmation message, then one when it is listed; no list sold or shared.
