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.

The Federal GST Rate: 5% Everywhere in Canada
The federal Goods and Services Tax is 5% in every province and territory, set by the Canada Revenue Agency. What changes from province to province is what gets charged on top of it. Alberta, Yukon, the Northwest Territories and Nunavut charge nothing extra — the total sales tax there is just 5%. Every other province adds a provincial layer: either by merging it with GST into a single HST, or by running a separate PST or QST alongside it. That second layer is why a $100 purchase costs $105 in Calgary but $113 in Toronto and $114.98 in Montreal.
HST Provinces: One Combined Tax (13% to 15%)
Ontario (13%), Nova Scotia (14%), New Brunswick, Newfoundland and Labrador, and Prince Edward Island (all 15%) use the Harmonized Sales Tax. HST merges the 5% federal GST and the provincial portion into one tax, collected together and remitted to the CRA as a single amount. Note Nova Scotia's rate: it dropped from 15% to 14% on April 1, 2025 (5% federal + 9% provincial) — many older tables and tools still show 15%. Our calculator splits the federal and provincial portions on separate lines so you can see exactly where each dollar goes.
PST and QST (Quebec): Separate Provincial Taxes
British Columbia (PST 7%), Saskatchewan (PST 6%) and Manitoba (PST 7%) charge a Provincial Sales Tax that is collected separately from GST — two taxes, two registrations, two lines on the invoice. They are parallel: both apply to the pre-tax price, and PST is not charged on top of GST. Quebec works the same way with its QST at 9.975%, administered by Revenu Québec. Because QST has its own rules and a dedicated reverse-calculation workflow, we built a separate tool for it. Selling to Quebec? Use the Quebec GST/QST Calculator for the full breakdown.
How This Calculator Works
Add mode treats your amount as the pre-tax price: GST is 5% of it, and the provincial tax (HST portion, PST or QST) is its rate applied to the same base. Remove and Reverse mode treat your amount as the tax-inclusive total: the calculator divides by 1 plus the combined rate (for Ontario, divide by 1.13; for Nova Scotia, 1.14; for Quebec, 1.14975) to recover the base price, then splits the tax back into its federal and provincial lines. The same math powers both directions — pick the mode that matches what you are holding: a quote (add) or a receipt (remove or reverse).
Common Mistakes with Canadian Sales Tax
The most expensive mistake is charging your home province's rate to out-of-province customers: place-of-supply rules say you charge the rate of the destination province, so an Ontario seller shipping to British Columbia charges 5% GST, not 13% HST. Second: subtracting the percentage to remove tax — dividing by 1.13 is correct for Ontario, multiplying by 0.87 is not. Third: using Nova Scotia's old 15% rate after the April 2025 drop to 14%. Fourth: assuming PST stacks on top of GST — both apply to the pre-tax price in BC, Saskatchewan, Manitoba and Quebec.

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.
