Sales Tax in Ontario (2026)
Ontario is a harmonized province: instead of charging GST and PST separately, it applies a single 13% Harmonized Sales Tax (HST). This 13% is made up of the 5% federal GST and an 8% provincial component, but on an invoice it appears as one combined HST line, which makes Ontario invoicing simpler than in PST provinces.

What's Taxed and What's Exempt
Ontario HST follows federal GST exemption rules: basic groceries, prescription drugs, and most medical devices are exempt or zero-rated. Ontario also provides point-of-sale rebates of the provincial portion on certain items such as childrens clothing, books, and diapers, so the effective rate on those is 5%.
How to Calculate ON Sales Tax

CA$1,000 × 0.13 = CA$130 HST. Total = CA$1,130Example — 13% on a CA$1,000 invoice
- Amount before tax: CA$1,000.00
- HST 13% = CA$130.00
- Total = CA$1,130.00
Reverse Calculation (Tax-Included Price)
If a price already includes tax and you need the pre-tax amount:
CA$1,130 ÷ 1.13 = CA$1,000 before taxInvoice Requirements in Ontario
An Ontario invoice should show your HST registration number, the pre-tax amount, the 13% HST as a single line, and the total. Because Ontario is harmonized, you do not list GST and PST separately.
