GST+PST provinces (BC, Manitoba, Saskatchewan, Quebec) add provincial tax separately. This GST/HST calculator handles all rates—use it for invoices, receipts, or reverse-calculating tax from a total.

What is GST?
GST (Goods and Services Tax) is the federal sales tax in Canada, at 5% on most goods and services. It applies in all provinces and territories. In HST provinces (Ontario, New Brunswick, Newfoundland and Labrador, Nova Scotia, PEI), GST is harmonized with provincial tax into a single HST rate. In other provinces (BC, Manitoba, Saskatchewan, Quebec, Alberta, territories), GST is charged separately from provincial sales tax (PST, RST, QST) where it exists. Use our GST/HST calculator Canada to add or remove the correct rate for your province.
What is HST, PST, and QST?
HST (Harmonized Sales Tax) combines federal GST and provincial tax into one rate in Ontario (13%), New Brunswick (15%), Newfoundland and Labrador (15%), Nova Scotia (14%, as of April 2025), and PEI (15%). PST (Provincial Sales Tax) is charged separately in BC (7%), Manitoba (7% RST), and Saskatchewan (6%). QST (Quebec Sales Tax) is 9.975% in Quebec, combined with 5% GST for 14.975% total. Alberta, Northwest Territories, Nunavut, and Yukon have no provincial sales tax—only 5% GST. The calculator above uses these rates automatically when you select your province.
How to add or remove GST/HST: formulas
To add sales tax: multiply the price by (1 + rate). Example: $100 in Ontario × 1.13 = $113. To remove sales tax: divide the total by (1 + rate). Example: $113 ÷ 1.13 = $100 before tax. Our calculator does this for you—choose add or remove, select your province, and enter the amount. For income tax (not sales tax), use our Canada Tax Calculator for take-home pay by province, or our Net to Gross Calculator Canada to work backward from desired take-home.
