A $250 purchase costs $282.50 in Ontario, $280.00 in British Columbia and $262.50 in Alberta. Type any price below, pick a province and the calculator adds the sales tax, or takes it back out of a total. Shelf prices here almost never include tax, so the number on the tag isn’t what leaves your wallet.
Which sales tax do you pay where?
Canada has one federal sales tax, the 5% GST, and every province decides what to put on top. Five provinces merged the two into a single harmonized tax, the HST. Four provinces charge their own tax next to the GST, and four places charge GST only.
| Where | What you pay | Rate on the price |
|---|---|---|
| Ontario | HST | 13% |
| New Brunswick, Newfoundland and Labrador, Prince Edward Island | HST | 15% |
| Nova Scotia | HST | 14% |
| British Columbia and Manitoba | GST plus 7% PST | 12% |
| Saskatchewan | GST plus 6% PST | 11% |
| Quebec | GST plus 9.975% QST | 14.975% |
| Alberta, Yukon, Northwest Territories, Nunavut | GST only | 5% |
Where the sale happens usually decides the rate. If you order online and have it shipped, you’ll normally pay the rate of the place it’s delivered to, even when the shop sits in another province. The CRA’s page on GST/HST place-of-supply rules spells this out for sellers.
The gap adds up fast on bigger buys. On a $20 item, Ontario and Alberta differ by $1.60, a loonie and change. On a $1,000 laptop the difference is $80, because it carries $130 of HST in Ontario and $50 of GST in Alberta.
How do you take the tax out of a total?
Say your receipt shows only the final amount. You’ll want to work backwards with the combined rate. In Ontario the total is 1.13 times the base price, so $113 is a $100 item plus $13 of HST. Taking 13% of $113 gives $14.69, and that’s wrong, because the tax was charged on the smaller base. The same trick works elsewhere: divide by 1.14 in Nova Scotia, so a $228 total is a $200 item plus $28 of tax, and by 1.12 in British Columbia. Choose the option for an amount that already includes tax and the calculator does the division for you. The reverse HST calculator is built for just this job.
Why is Quebec different?
Quebec applies the QST to the base price alone, and GST is never part of what the QST is charged on. A $100 item carries $5.00 of GST and $9.98 of QST, so it costs $114.98. The GST and QST calculator shows both lines. In British Columbia, Saskatchewan and Manitoba the provincial tax is billed on its own line, so the GST and PST calculator is more direct there.
What isn’t taxed, or is taxed less?
Some goods and services carry a 0% rate. Think unprepared food, prescription drugs and exports. Others are exempt, like most health care and long-term rent. Businesses care about the difference, because a zero-rated sale lets them claim back the tax they paid on their costs, while an exempt sale doesn’t, and that can change what a seller charges you in the end. The calculator always applies the full rate, so it’ll overstate the tax on bread, milk or a prescribed medical device.
Does every seller charge you tax?
No. A seller has to register for a GST/HST number once its taxable sales pass $30,000 in a single calendar quarter, or over four calendar quarters in a row. The CRA’s guide for GST/HST registrants calls anyone under those limits a small supplier. Past the line, the seller collects the tax on each sale and remits it. Below it, registering is the seller’s call, which is why a weekend craft vendor or a part-time tutor may not add any tax to your bill.
What about a new home?
A new home carries the full tax on a big price, though rebates cover part of it. The new home rebate calculator works out the federal rebate, the first-time buyer rebate and the Ontario share. Add land transfer tax and you have the full cost at closing, which the land transfer tax calculator shows.
Why is my receipt a cent off?
Store systems round each line on its own, so your receipt can land a cent away from the figure here. Nothing is wrong with either number.
Where these rates come from
GST and HST rates come from the federal rate table, and PST and QST from the finance departments of the provinces that charge them. The CRA’s GST/HST rates by province page lists the same federal and provincial figures as the table above. Nova Scotia cut its HST from 15% to 14% on 1 April 2025. This website has no connection with any tax authority.
