How the GST/HST Calculator Works
The GST/HST calculator for Canada is a free browser-based tool that computes federal and provincial sales tax for all 13 provinces and territories. Canada uses three types of sales tax depending on the province: GST (Goods and Services Tax) at 5% federally, HST (Harmonized Sales Tax) which combines GST and provincial tax into a single rate, and PST (Provincial Sales Tax) which is charged separately from GST in some provinces. Based on 2026 rates from the Canada Revenue Agency, this calculator handles all three systems automatically when you select your province.
GST, HST, and PST Rates by Province
Five provinces charge HST: Ontario at 13%, and New Brunswick, Newfoundland and Labrador, Nova Scotia, and Prince Edward Island all at 15%. Four provinces charge GST plus a separate PST: British Columbia (5% GST + 7% PST = 12%), Saskatchewan (5% GST + 6% PST = 11%), Manitoba (5% GST + 7% PST = 12%), and Quebec (5% GST + 9.975% QST = 14.975%). Alberta, Northwest Territories, Nunavut, and Yukon charge only the 5% federal GST with no provincial sales tax. Quebec calls its provincial tax QST (Quebec Sales Tax) and administers it through Revenu Quebec rather than the CRA.
Add Tax vs Remove Tax: Which Should You Use?
Use "Add tax" when you know the pre-tax price and want to calculate the final amount including all applicable sales tax. This is the standard mode for pricing goods and services. Use "Remove tax" when you have a receipt total and want to determine how much of that total was tax versus the original price. The reverse calculation divides by (1 + combined tax rate) rather than multiplying, which gives you the exact pre-tax amount and tax paid. This is useful for expense reports, bookkeeping, and filing GST/HST returns with the CRA.
Tips for Canadian Business Owners
Businesses with annual revenue over $30,000 must register for a GST/HST account and charge the applicable tax. You can claim Input Tax Credits (ITCs) to recover the GST/HST paid on business expenses. Small suppliers under the $30,000 threshold can voluntarily register to claim ITCs. File your GST/HST return quarterly or annually depending on your revenue level. Keep all receipts showing the tax paid, as the CRA may audit your ITC claims. Last updated: April 2026.
