Sales tax across Canada
Canada has three sales-tax systems depending on the province. Some use a single HST (Harmonized Sales Tax) that combines federal and provincial portions; others charge the federal GST (5%) plus a separate provincial PST; Alberta and the territories charge GST only; and Quebec adds its own QST. Because the rules and the rate depend entirely on where a sale takes place, the same $100 item can cost a different total in Toronto, Vancouver, Montreal or Calgary. This calculator picks the correct method and rate for the province you select, so you do not have to remember which system applies.
What each input means
- Amount — the price you're taxing. Depending on the mode, this is either the pre-tax price (to add tax) or the tax-included price (to work backwards).
- Province — determines which system and rate apply (HST, GST + PST, GST + QST, or GST only).
- Add vs. remove tax — "Add tax" builds the total from a pre-tax price; "Remove tax" extracts the pre-tax price and tax from a tax-included total.
How Canadian sales tax works
There is no single national sales tax in Canada. Instead, a federal tax and provincial taxes work together in one of a few combinations. Understanding the four building blocks makes the totals easy to follow.
GST (federal). The Goods and Services Tax is charged by the federal government at 5% and applies almost everywhere in the country. In provinces and territories that have no provincial sales tax of their own, the 5% GST is the only sales tax you pay.
PST (provincial). Some provinces run their own Provincial Sales Tax on top of the federal GST. In these provinces you see two separate lines — the 5% GST plus the province's own PST — and both are generally calculated on the pre-tax price rather than one being stacked on the other.
HST (harmonized). A few provinces chose to merge the federal and provincial portions into one blended Harmonized Sales Tax. You are charged a single combined rate and see one tax line instead of two, even though part of that money is still the federal 5%.
QST (Quebec). Quebec administers its own Quebec Sales Tax alongside the federal GST. It behaves much like a PST but is run by Revenu Québec. In Quebec you see a GST line and a QST line, and the calculator labels the provincial portion accordingly.
Whichever system applies where you are, the underlying idea is the same: take the pre-tax price, apply the right rate or rates, and add the result to reach the final total.
2026 rates by province
| Type | Provinces | Combined |
|---|---|---|
| HST | ON | 13% |
| HST | NS | 14% |
| HST | NB, NL, PE | 15% |
| GST + PST | BC | 12% |
| GST + PST | SK | 11% |
| GST + PST | MB | 12% |
| GST + QST | QC | 14.975% |
| GST only | AB, YT, NT, NU | 5% |
Where these rates come from. Federal GST and the participating-province HST rates are set by the Canada Revenue Agency; provincial sales taxes are set by each province. Nova Scotia’s HST fell to 14% on 1 April 2025 — a change several calculators still have not applied.

Reverse HST and GST calculation — finding the price before tax
Switch to "Remove tax" to work backwards from a tax-included price — useful for expense claims or figuring out the pre-tax cost of something you've already bought.
Worked example
Suppose you buy a $100 item in a province that uses a single 13% HST. The tax is $100 × 13% = $13, for a total of $113. In a province that charges 5% GST plus a 7% PST instead, both are usually figured on the $100 base: $5 GST + $7 PST = $12 tax, or $112 total. Working backwards, if a receipt shows $113 including 13% HST, the pre-tax price was $113 ÷ 1.13 ≈ $100. (Rates here are illustrative — the calculator uses the correct rate for the province you pick.)
The three systems, and why your province matters
Canada does not have one sales tax. It has three arrangements, and which one you are in changes both the rate and what the tax applies to:
- HST provinces — Ontario and the Atlantic provinces fold the federal and provincial portions into one Harmonized Sales Tax, collected together and administered federally. One rate, one line on the receipt.
- GST + PST provinces — British Columbia, Saskatchewan and Manitoba charge the 5% federal GST plus a separate provincial tax administered by the province. Two taxes, two sets of rules, two lists of exemptions.
- GST only — Alberta and the three territories levy no provincial sales tax at all, so you pay the 5% GST and nothing more.
The distinction matters beyond arithmetic. In an HST province, a business generally recovers the full tax it pays on inputs. In a GST + PST province it usually recovers the GST but not the PST, which becomes a real cost embedded in the price. That is why the same product can carry a different final price in Saskatchewan than in Ontario even when the headline rates look similar.
Where the provincial systems differ in practice
The provincial taxes are not simply different percentages of the same thing — they apply to different things.
- Quebec (QST) — administered by Revenu Québec rather than the CRA. QST is calculated on the price before GST, so the two are not compounded, though people often assume they are.
- Saskatchewan (PST) — applies more broadly than most, reaching a range of services that are untaxed elsewhere. If you are comparing a Saskatchewan quote against another province's, check whether the service itself is taxable, not just the rate.
- British Columbia (PST) — carries a long list of specific exemptions, and applies special rates to some categories such as vehicles and accommodation rather than one flat provincial rate.
- Manitoba (RST) — the Retail Sales Tax works on similar principles but maintains its own exemption list.
Across all provinces, basic groceries, prescription drugs and most medical devices are zero-rated federally, so a grocery receipt can show tax on some lines and none on others. Because provincial exemption lists change with each budget, this calculator applies the standard combined rate for the province you pick — for an unusual category, confirm against your province's tax authority before relying on the figure.
How much is GST and PST where you live?
The short answer: GST is 5% everywhere in Canada. What changes is the provincial half — some provinces add a separate PST, some merge both into one HST, and some charge nothing on top of the federal 5% at all.
| Province / territory | GST | PST / QST | Total you pay |
|---|---|---|---|
| Alberta, Yukon, NWT, Nunavut | 5% | none | 5% |
| Saskatchewan | 5% | 6% PST | 11% |
| British Columbia | 5% | 7% PST | 12% |
| Manitoba | 5% | 7% PST | 12% |
| Ontario | 13% HST (combined — no separate PST) | 13% | |
| Nova Scotia | 14% HST | 14% | |
| New Brunswick, Newfoundland & Labrador, PEI | 15% HST | 15% | |
| Quebec | 5% | 9.975% QST | 14.975% |
How much is PST in Ontario?
Ontario has no PST. This is the single most common misunderstanding about Canadian sales tax. Ontario replaced its separate provincial sales tax in 2010 by merging it with the federal GST into one 13% HST. So there is no Ontario PST rate to look up — a $100 purchase in Ontario costs $113, and the entire $13 is HST. If a receipt in Ontario shows a line labelled "PST", it is almost certainly mislabelled HST.
How much is GST and PST in BC?
12% in total — 5% federal GST plus 7% provincial PST, charged as two separate lines. On a $100 purchase that is $5.00 GST and $7.00 PST, for $112.00. British Columbia is one of the provinces that never harmonized, which is why you see both taxes itemized rather than a single HST figure. The two are calculated independently on the pre-tax price; PST is not charged on top of the GST.
How much is PST on its own?
PST only exists in three provinces, and the rate differs in each: Saskatchewan 6%, British Columbia 7%, Manitoba 7%. Quebec charges an equivalent tax called QST at 9.975%. Everywhere else in Canada there is no PST at all — either because the province harmonized it into HST (Ontario and the Atlantic provinces) or because it never had one (Alberta and the three territories).
Which province has the lowest sales tax?
Alberta, Yukon, Northwest Territories and Nunavut, at 5% — they charge only the federal GST with nothing provincial on top. The highest is the 15% HST in New Brunswick, Newfoundland & Labrador and Prince Edward Island. On a $1,000 purchase that is a $100 difference depending purely on where you buy it.
Frequently asked questions
Which provinces actually charge PST?
Only three: Saskatchewan at 6%, British Columbia at 7% and Manitoba at 7%. Quebec charges an equivalent tax called QST at 9.975%. Everywhere else either uses HST or charges only the 5% federal GST.
What are GST, HST and PST?
These are Canada's sales taxes. GST (Goods and Services Tax) is the federal tax applied across the country. PST (Provincial Sales Tax) is charged separately by some provinces. HST (Harmonized Sales Tax) is a single combined tax used in provinces that have merged the federal and provincial portions into one rate.
How is Canadian sales tax calculated?
You multiply the item's price by the applicable tax rate for your province, then add it to the price. This calculator handles GST, HST or GST-plus-PST depending on where you are, so you get the correct tax amount and final total for your province.
Which provinces use HST versus GST and PST?
Provinces that use HST charge one combined rate. Others charge the federal GST plus their own separate PST, and a few charge only GST. Because the setup differs by province, the total sales tax on the same item varies depending on where you buy it.
Do GST and PST apply on top of each other?
In most provinces that use separate taxes, GST and PST are each calculated on the item's base price rather than stacked on one another. This calculator applies the correct method for your province so the total is accurate.
Are any goods exempt from GST/HST?
Yes. Certain items such as basic groceries, some medical devices and prescription drugs are zero-rated or exempt from GST/HST. Provincial rules for PST exemptions vary, so check your province's guidance for specific categories.
How do I remove tax from a total price?
Divide the tax-included price by 1 plus the tax rate. For example, at a 13% rate, $113 ÷ 1.13 ≈ $100 pre-tax, leaving $13 of tax. Switch this calculator to "Remove tax" and it does this automatically for your province.
Why does the same item cost more in another province?
Because sales tax is set province by province. A province with 15% HST adds more tax than one charging only the 5% federal GST, so the same pre-tax price reaches a higher total. Where the sale happens decides the rate.
Do I charge sales tax if I sell online across Canada?
Generally the tax that applies is based on where the customer is (the place of supply) rather than where you're located, and registration thresholds apply. The rules can be involved, so check the CRA's guidance or a tax professional for your situation.
