Four Canadian provinces charge a separate provincial sales tax: British Columbia and Saskatchewan call it PST, Manitoba calls it RST, and Québec calls it QST. These taxes are charged separately from the 5% federal GST.
Provinces using HST do not charge a separate PST. Alberta and the three territories charge GST but have no separate provincial or territorial sales tax.
In New Brunswick, Newfoundland and Labrador, Nova Scotia, Ontario and Prince Edward Island it is part of HST (Harmonized Sales Tax)
Northwest Territories, Nunavut and Yukon have no territorial sales tax at all.
Use this calculator to find the provincial sales tax, price before tax, or price after tax in British Columbia, Manitoba, Québec or Saskatchewan. Select a province and enter an amount in any one field; the other fields update automatically. Federal GST is not included.

How PST is calculated
For a price before tax:
Provincial tax = price before tax × tax rate
Price after tax = price before tax + provincial tax
Example: A $100 taxable purchase in Saskatchewan at 6% PST produces $6 in PST and a total price of $106.
For a price that already includes tax:
Price before tax = price after tax ÷ (1 + tax rate)
Provincial tax = price after tax − price before tax
Example: A total price of $107 in British Columbia at 7% PST contains $7 in PST and a $100 price before tax.
Results are rounded to two decimal places and may differ by a cent from a retailer’s invoice.
B.C. update: Effective October 1, 2026, PST expands to selected professional services. The general rate remains 7%, but some services have special calculation rules. See the official B.C. Government notice.
These are general provincial sales tax rates. Taxability and exemptions vary by product or service. This calculator estimates PST, RST or QST only; it does not include federal GST.
A brief history of PST in Canada
Provincial sales taxes developed separately from the federal GST, which is why their names, rates and rules differ. Several provinces later combined their provincial tax with GST under the Harmonized Sales Tax (HST). British Columbia, Manitoba, Québec and Saskatchewan continue to operate separate provincial sales tax systems.
British Columbia used HST from July 1, 2010, until March 31, 2013. It returned to a separate 7% PST and 5% GST system on April 1, 2013.
Saskatchewan increased its general PST rate from 5% to 6% on March 23, 2017. Manitoba reduced its general RST rate from 8% to 7% on July 1, 2019.
This calculator uses current standard rates and does not calculate historical taxes. For an older invoice or transaction, use the rate and tax rules that applied on the transaction date.
