Sales tax in Canada varies more than almost any other tax. Some provinces charge a single harmonized tax (HST), some add a separate provincial tax (PST or QST) on top of the federal GST, and Alberta and the three territories charge only the 5% federal GST. This calculator applies the right combination for whichever jurisdiction you choose and breaks the total into its parts.
It is handy for quoting jobs, checking invoices, or pricing a purchase before you reach the till.
Understanding the numbers
GST, HST, PST and QST
GST is the 5% federal tax. HST provinces fold the provincial portion into one combined rate. PST (and Quebec's QST) is a separate provincial tax charged alongside GST. The calculator shows each component that applies.
Alberta's advantage
Alberta has no provincial sales tax, so only the 5% GST applies — the lowest combined sales-tax burden in Canada and a real saving on large purchases compared with other provinces.
Rounding
Amounts are shown to the cent. Retail systems may round slightly differently, but the totals here match the statutory rates.

GST, HST, PST and QST sales tax calculator for every Canadian province
Canada's sales tax is not one tax — it is several
Sales tax is the area where the provinces diverge most. There are four distinct systems in Canada, and this calculator applies the correct one for whichever jurisdiction you select rather than assuming a single national rate. Alberta and the three territories charge only the 5% federal GST. British Columbia, Saskatchewan and Manitoba add a separate provincial sales tax on top of the GST (Manitoba calls its version the Retail Sales Tax, or RST). Quebec adds the Quebec Sales Tax (QST), administered by Revenu Québec. Ontario and the Atlantic provinces use a single Harmonized Sales Tax (HST) that blends the federal and provincial portions into one rate.
For businesses and shoppers in Sherwood Park, the practical takeaway is simple: Alberta's 5% GST-only regime is the lightest sales-tax burden in the country. The same $1,000 purchase costs $50 in tax here, versus $130 in Ontario or $149.75 in Quebec. The breakdown below shows every jurisdiction at a glance.
GST registration and collection for Alberta businesses
Whether you sell from Sherwood Park, Edmonton or online across Canada, the place-of-supply rules generally require you to charge the sales tax of the province where the customer receives the goods or service — not where your business is located. That means an Alberta business selling into Ontario may need to charge 13% HST, and one selling into British Columbia may need to handle both GST and BC PST. Getting this right protects you from assessments and interest.
Registration for GST/HST is mandatory once your taxable revenue exceeds $30,000 over four consecutive quarters, and voluntary registration below that lets you recover the GST you pay on business purchases through input tax credits. We set up multi-province tax collection, file your GST/HST returns, and make sure you are claiming every input tax credit you are entitled to.
