How Canadian Sales Tax (GST/HST/PST/QST) Is Calculated: Formulas & Mathematical Models
Official algorithms and place-of-supply calculation models for Canadian federal, harmonized, and provincial sales taxes.
Adding Tax
Explains how the total invoice amount is calculated by applying the combined statutory tax rate (federal GST plus provincial PST/QST, or a single harmonized HST) to the pre-tax net selling price. Canadian sales taxes are additive (non-compounded) and calculated directly on the net base price.
Extracting Tax
Reverse-calculates the pre-tax base cost and exact tax breakdown from a tax-inclusive receipt or gross invoice by dividing the total by 1 plus the combined statutory tax rate.

Frequently Asked Questions (FAQ)
QHow are Canadian sales taxes structured?
Canada uses a multi-tier tax system. The Goods and Services Tax (GST) is a 5% federal tax. Many provinces harmonize this with their provincial tax to form the Harmonized Sales Tax (HST). Others, like BC and Saskatchewan, charge a separate Provincial Sales Tax (PST), while Quebec charges the Quebec Sales Tax (QST).
QWhat changed with the Nova Scotia HST rate in 2025?
Effective April 1, 2025, Nova Scotia lowered its provincial portion of the HST by 1%, bringing the combined HST rate down from 15% to 14%.
QHow is Quebec's QST calculated?
The Quebec Sales Tax (QST) is currently 9.975%. It is calculated additively on the base (net) amount, just like the 5% GST. The combined effective tax rate in Quebec is 14.975%.
QHow do I extract tax backwards from a total?
To find the net amount before tax, divide the gross total by (1 + the combined tax rate). For example, if the total is $113 and the HST is 13%, the net amount is $113 / 1.13 = $100.
QWhat items are PST exempt in Canada?
Certain goods and services, such as children's clothing, basic groceries, and printed books, may be exempt from the provincial portion of the sales tax (PST) in provinces that maintain a separate PST system. In these cases, only the 5% federal GST applies.
QDo I charge sales tax for out-of-province sales?
If you are a registered Canadian business selling to another province, you typically charge the sales tax rate of the province where the goods or services are delivered (place of supply rules), rather than your home province rate.
