Canada GST/HST Calculator (All 13 Provinces)
Add, remove or reverse GST, HST, PST and QST for every Canadian province and territory — official rates, always split line by line.
HST is a single combined tax: the 5% federal part and the provincial part are collected together.
What this result means for you
In Ontario: a base price of $100.00 carries $5.00 federal GST plus $8.00 provincial tax, for a total of $113.00. To reverse a tax-inclusive total back to the base, divide by 1.13000 — never subtract the percentage.
Place-of-supply trap: tax follows the destination, not your office. If an Ontario seller ships this $100.00 order to a BC customer and charges Ontario's 13% HST ($13.00) instead of the 5% GST that applies ($5.00), the customer is overcharged $8.00 — and fixing misapplied tax after invoicing means credit notes and CRA paperwork.

Canada GST/HST Calculator FAQ
Q1.How is GST calculated in Canada?
Multiply the pre-tax price by 5% — that is the federal GST everywhere in Canada. In HST provinces the provincial portion is collected with it as one combined tax (13% in Ontario, 14% in Nova Scotia, 15% in NB, NL and PEI). In BC, Saskatchewan, Manitoba and Quebec, a separate PST or QST applies to the same pre-tax price in parallel. To extract tax from a tax-inclusive total, divide by 1 plus the combined rate instead.
Q2.How much GST do you charge?
Charge 5% federal GST, plus the provincial tax of the customer's province under place-of-supply rules: nothing extra in Alberta and the territories, HST of 13-15% in Ontario and the Atlantic provinces, PST of 6-7% in BC, Saskatchewan and Manitoba, or QST of 9.975% in Quebec.
Q3.Is GST always 5%?
The federal GST rate has been 5% since 2008 and applies at 5% in every province and territory. What varies is the provincial layer on top: combined rates range from 5% (Alberta, Yukon, NWT, Nunavut) to 15% (New Brunswick, Newfoundland and Labrador, PEI). Some essentials are zero-rated (0%), such as basic groceries and prescription drugs.
Q4.Is GST the same as VAT?
They are the same type of tax — a value-added tax collected at each stage of the supply chain with input tax credits. Canada calls its version GST/HST; the UK and EU call theirs VAT. The mechanics match, but rates and registration rules differ by country, so a UK VAT figure can't be reused for Canadian GST.
Q5.Does Alberta charge GST or PST?
Alberta charges only the 5% federal GST — it has no provincial sales tax at all, the only province without one. The territories (Yukon, Northwest Territories, Nunavut) are the same. A $100 purchase in Calgary totals exactly $105.
Q6.Does BC's 7% PST stack on top of the 5% GST?
No. BC PST and GST are parallel taxes: both are calculated on the pre-tax price. On a $100 purchase you pay $5 GST plus $7 PST — $112 total. PST is not charged on the GST-inclusive $105, which would give a different (wrong) figure of $112.35.
Q7.Is Ontario HST 13% or 15%?
Ontario HST is 13% — 5% federal plus 8% provincial. The 15% rate belongs to New Brunswick, Newfoundland and Labrador, and Prince Edward Island. Nova Scotia sits between at 14% after its April 2025 rate cut. A $100 purchase in Ontario totals $113.
Q8.How is Quebec's QST different from HST?
QST is a separate provincial tax (9.975%) administered by Revenu Québec, not part of the federal HST system. Like PST, it is calculated in parallel on the pre-tax price alongside the 5% GST, for an effective combined rate of 14.975%. Invoices show GST and QST as two distinct lines. For the full Quebec breakdown, use our Quebec GST/QST Calculator.
Q9.If I sell from Ontario to BC, which tax do I charge?
Place-of-supply rules follow the destination: for goods shipped to a BC address you charge 5% GST (BC's federal-only rate for out-of-province GST registrants), not Ontario's 13% HST. Whether you must also collect BC PST depends on BC's separate PST registration thresholds for remote sellers. Reversed direction works the same way — a BC seller shipping to Ontario charges 13% HST.
Q10.What's the difference between PST and HST?
HST is one combined federal-provincial tax collected together and remitted to the CRA — one registration, one line. PST is a separate provincial tax with its own registration and remittance to the province, charged in parallel with GST — two lines on every invoice. Ontario and the Atlantic provinces use HST; BC, Saskatchewan and Manitoba use GST + PST; Quebec uses GST + QST.
