    General information only. Rates are the standard 2026 GST/HST and provincial sales tax rates, including Nova Scotia's reduction to 14% on April 1, 2025. Some goods and services are exempt or zero-rated, and a few provinces apply PST differently to specific items. Confirm anything unusual with the CRA or your provincial tax authority.

    GST, HST, and PST explained

    Canada has a 5% federal Goods and Services Tax (GST) that applies everywhere. Five provinces fold their provincial tax into the GST as a single Harmonized Sales Tax (HST). The rest charge the 5% GST plus a separate provincial tax, a Provincial Sales Tax (PST) in BC and Saskatchewan, a Retail Sales Tax (RST) in Manitoba, and the Quebec Sales Tax (QST) in Quebec. Alberta and the three territories have no provincial sales tax, so only the 5% GST applies.

    Adding tax vs. removing tax

    Adding tax takes a pre-tax price and works out the tax and the final total. Removing tax does the reverse: it takes a total that already includes tax and backs out the original price and the tax inside it, which is what you need when a receipt shows only the total. The calculator does both, switched with the toggle at the top.

    A note for landlords

    Residential rent is generally exempt from GST/HST, so it is not charged on a tenant's rent, though taxable supplies and commercial rent are treated differently. For the rent side of the ledger, see our rental income tax estimator and other free tools.

    Frequently asked questions

    How do I calculate HST?

    Multiply the pre-tax amount by the HST rate for your province. In Ontario that is 13%, so a $100 item has $13 of HST and a $113 total. This calculator does it for every province and shows the breakdown.

    How do I remove HST from a total?

    Divide the tax-included total by one plus the rate. For a $113 total in Ontario (13% HST), the pre-tax amount is 113 ÷ 1.13 = $100, so the HST was $13. Switch the calculator to “Remove tax” to do this automatically.

    What is the difference between GST, HST, and PST?

    GST is the 5% federal tax that applies across Canada. In some provinces it is combined with the provincial tax into a single Harmonized Sales Tax (HST). Other provinces charge GST plus a separate Provincial Sales Tax (PST), Retail Sales Tax (RST), or Quebec Sales Tax (QST).

    Which provinces use HST?

    Ontario (13%), Nova Scotia (14% since April 1, 2025), and New Brunswick, Newfoundland and Labrador, and Prince Edward Island (15% each). BC, Manitoba, Saskatchewan, and Quebec charge GST plus a separate provincial tax. Alberta and the three territories charge only the 5% GST.

    Is GST/HST charged on rent?

    Residential rent is generally exempt from GST/HST, so a landlord does not charge it on a tenant's rent. Commercial rent is usually taxable. This is a common point of confusion, so confirm your situation with the CRA.
