GST/HST only; PST/QST, exemptions, rebates, input tax credits and place-of-supply rules may change the actual invoice.
Estimate only. A bank, employer, tax office or lender may apply additional conditions. See the scope and source below.
When and how to use this calculator
On a C$1,000 taxable Ontario sale quoted before tax, add 13% HST (C$130) for a C$1,130 total. If C$1,130 already includes HST, divide by 1.13 first to find the C$1,000 pre-tax price.
- Determine whether the supply is taxable, zero-rated or exempt. The type of supply affects the tax, not just the customer's province.
- Determine the correct place of supply before selecting a CRA GST/HST rate: 5%, 13%, 14%, 15%, or zero-rated 0%. Do not treat 0% as an exemption without verifying GST registration rules.
- Select whether the number you enter is tax-exclusive or tax-inclusive, and separately account for provincial PST or QST where applicable.
Understand your result
GST/HST component only: excludes PST, QST, place-of-supply determinations, exemptions, taxable supply classification, input-tax-credit entitlement and provincial tax calculations. User is responsible for choosing the applicable rate.
Questions people ask
Does British Columbia always charge only 5% total sales tax?
No. BC commonly has GST plus provincial sales tax on applicable goods and services; this calculator includes only federal GST/HST.
What happened to Nova Scotia's HST rate in 2025?
It became 14% on 1 April 2025 according to CRA; check whether the supply date requires the earlier rate.
Are groceries taxed at zero percent?
Many basic groceries are zero-rated GST/HST, but other supplies may be exempt or taxable. Classify the actual supply first.
