Canada Revenue Agency →How this calculator computes HST
Add Tax: Total = Base Price × (1 + rate)
Remove Tax: Base = Total Price ÷ (1 + rate)
Tax Amount = Total − Base Price
Methodology: For HST provinces (Ontario, Nova Scotia, New Brunswick, Newfoundland & Labrador, PEI) a single combined rate is applied to the base price. For provinces with separate GST and PST/QST/RST (BC, Quebec, Manitoba, Saskatchewan), both components are calculated independently against the pre-tax base — consistent with CRA guidance in the CRA GST/HST rate calculator. Alberta, Yukon, Northwest Territories and Nunavut apply only the 5% federal GST.
What Is HST in Canada?
The Harmonized Sales Tax (HST) is a consumption tax that combines the federal Goods and Services Tax (GST) with a provincial sales tax component into a single, streamlined tax. It applies to most goods and services sold in participating provinces and is collected by the Canada Revenue Agency (CRA) on behalf of both the federal and provincial governments.
HST was introduced to simplify the dual tax system that previously required businesses and consumers to calculate and remit two separate taxes at the point of sale. Not every province has harmonized; some, like British Columbia, Saskatchewan, and Quebec, still operate separate GST and PST/QST systems.
Which provinces have HST?
As of 2026, five provinces participate in the HST system: Ontario (13%), Nova Scotia (15%), New Brunswick (15%), Newfoundland and Labrador (15%), and Prince Edward Island (15%). All other provinces collect the federal GST (5%) alongside a separate provincial tax.

How to Calculate HST in Ontario
Ontario charges a combined HST of 13% (5% federal GST + 8% Ontario component). To add HST to a pre-tax price, use the following formula:
HST Amount = Base Price × 0.13
Total Price = Base Price × 1.13
Example: $100.00 × 1.13 = $113.00 (total including HST)
Step-by-step example
- A plumber charges $850.00 for labour in Toronto, Ontario.
- HST = $850.00 × 0.13 = $110.50
- Total invoice amount = $850.00 + $110.50 = $960.50
How to Calculate Reverse HST — Remove Tax from a Total
The reverse HST calculation (also called back-calculating or extracting tax) lets you find out how much of a total price was tax and what the original pre-tax price was. This is useful for expense claims, accounting entries, and reconciling receipts where only the total is shown.
Base Price = Total Price ÷ 1.13 (Ontario HST)
HST Amount = Total Price − Base Price
Example: $226.00 ÷ 1.13 = $200.00 base price · $26.00 HST
For provinces with separate GST and PST (e.g., British Columbia at 12%), the formula uses the combined rate:
Base Price = Total Price ÷ 1.12 (BC: 5% GST + 7% PST)
GST = Base Price × 0.05
PST = Base Price × 0.07
When do you need reverse HST calculation?
- Business expense reports — when employees submit receipts with tax included, accountants must extract the GST/HST to claim input tax credits (ITCs).
- Invoice reconciliation — verifying whether a vendor has charged the correct HST rate.
- Real estate transactions — determining the pre-tax portion of a purchase price for reporting purposes.
- Personal finance — understanding exactly how much tax you paid on a purchase.
