For example, if you sell a service to a client in Ontario for $500, select Ontario (13% HST) to calculate the $65 tax amount and $565 total. If you have a total receipt of $113 and want to find the base price, select Ontario and toggle the Reverse mode to extract the $13 tax and $100 subtotal.
Results are meant for quick planning and double-checking. For legal, tax, or financial decisions, review the numbers with a qualified professional.
The GST/HST calculator handles sales taxes across all Canadian provinces and territories. It automatically applies the appropriate federal GST rate (5%) and combines it with provincial sales taxes (PST) or Quebec sales tax (QST) where applicable, or applies the combined Harmonized Sales Tax (HST) rate for provinces participating in the HST system (Ontario, Nova Scotia, New Brunswick, PEI, and Newfoundland and Labrador). It operates in both forward mode (adding tax to a subtotal) and reverse mode (extracting tax from a total price).
Forward Tax = Subtotal x Tax Rate. Forward Total = Subtotal x (1 + Tax Rate). Reverse Subtotal = Total / (1 + Tax Rate). Reverse Tax = Total - Reverse Subtotal.
Alberta, Nunavut, NWT, and Yukon charge only 5% GST. Saskatchewan charges 5% GST + 6% PST (11%). Manitoba charges 5% GST + 7% RST (12%). British Columbia charges 5% GST + 7% PST (12%). Quebec charges 5% GST + 9.975% QST (14.975%). Ontario charges 13% HST. New Brunswick, Newfoundland & Labrador, Nova Scotia, and PEI charge 15% HST.
