GST/HST Calculator for Canada
Canadian GST/HST can vary by province and tax type. Enter a rate you have checked from an official source. This page is generated at build time and does not collect or store IDs or calculator inputs.
Tax calculations are for general estimation only and are not tax, accounting, or legal advice. Always confirm with your tax authority or a qualified professional. The calculator does not know registration status, marketplace collection rules, exemptions, thresholds, filing rules, or local tax law.
Canada page currency: CAD. Entering 0.00% as a rate does not mean this site has verified that rate for your sale.
This calculator separates net amount, GST/HST amount, and gross amount. It does not choose a tax rate for you. Enter only a rate you have checked for your sale, jurisdiction, product type, and seller status.

Manual-rate mode. No site-maintained GST/HST rate is supplied by this calculator, and no rate is inserted automatically.
The rate field is for a value you have checked yourself. Inputs stay in browser state only and should not include VAT IDs, TINs, or personal information.
For a CAD 100.00 sale, enter your checked tax rate and choose whether 100.00 is tax-exclusive or tax-inclusive. The calculator then shows net, tax, and gross amounts using decimal-safe arithmetic.
Tax-exclusive: tax amount = net amount x tax rate. Gross amount = net amount + tax amount.
Tax-inclusive: net amount = gross amount / (1 + tax rate). Tax amount = gross amount - net amount.
If you enter a checked rate of 20% and a net amount of CAD 100.00, the math example shows CAD 20.00 tax and CAD 120.00 gross.
This does not mean this site verified 20% as the correct rate for your sale.
