The tools
What are these tax tools?
TheBomb® tax tools are free Canadian sales tax calculators that show their work. They cover every province and territory, apply the 5% federal GST plus whatever that jurisdiction adds on top, and break the answer into the federal portion, the provincial portion, and the total.
Every rate the tools use comes from one file that we check against the Canada Revenue Agency and the provincial tax authorities, then date-stamp. Rates are not typed into individual pages, so when a province moves its rate, the calculators and the table below move with it.
Nothing is hidden behind a signup, nothing is emailed to you, and every number on the page is in the HTML before any script runs. Rates verified July 2026.
Who are these tools for?
- Owners quoting a job and pricing it with tax included.
- Freelancers and contractors billing a client in another province.
- Bookkeepers backing tax out of a receipt for an input tax credit.
- Shoppers who want to know what a shelf price becomes at the till.

Quick answers
Common questions about Canadian sales tax.
How much is GST in Canada?
GST in Canada is 5%. The federal Goods and Services Tax applies in every province and territory. In the five HST provinces the 5% federal portion is folded into one harmonized rate instead of being billed on its own line.
Which provinces have the lowest and highest sales tax?
Alberta, Yukon, the Northwest Territories and Nunavut have the lowest sales tax in Canada at 5%, because they charge GST only and add no provincial sales tax. New Brunswick, Prince Edward Island, and Newfoundland and Labrador have the highest at 15% HST.
How do you calculate GST from a total?
To calculate GST from a tax-included total, divide the total by 1 plus the combined tax rate, then apply each rate to the base. A $112.00 total in British Columbia divided by 1.12 gives a $100.00 base, $5.00 GST and $7.00 PST. The reverse GST calculator does that for every province and territory.
Is there PST on top of GST in BC?
Yes. British Columbia charges 7% PST on top of 5% GST, which is 12% in total. BC PST is calculated on the pre-tax price rather than on the GST, so the two taxes do not compound on each other.
Do these tools cover HST provinces as well as PST provinces?
Yes. The tools cover all 13 provinces and territories: the five HST provinces, the four GST-only jurisdictions, and the four that charge GST plus a separate provincial tax (BC PST, Saskatchewan PST, Manitoba RST, and Quebec QST).
