About this gst/hst canada tool

GST/HST Calculator Canada is designed for a focused everyday task where a quick browser-based calculation or conversion is more useful than a full spreadsheet. Review the inputs carefully, then use the result as a practical planning aid.

How this tool works

Enter the values requested by the page, review the result, and change one input at a time if you want to compare scenarios. Keeping the assumptions visible makes the output easier to interpret and easier to verify elsewhere.

1. Choose a GST/HST preset or enter a custom rate.
2. Enter an amount and choose whether to add tax or remove tax from an included total.
3. Review the estimated pre-tax amount, GST/HST amount, and total.

When to use this tool

Use the tool for quick checks, estimates, and everyday planning. For official, regulated, legal, tax, payroll, medical, or high-value decisions, verify the result with the relevant provider, authority, or qualified adviser.

Good to know

• Estimates only. Separate PST, QST, or RST may apply in some provinces and is not included unless it is part of an HST-style preset.
• Check CRA and province/territory guidance or professional advice before using figures for filing or invoicing decisions.

Country-specific assumptions

• GST/HST presets are editable planning constants and do not include separate PST, QST, or RST unless the province uses HST.
• Canadian mortgage payments use a common semi-annual compounding convention for estimates.
• Salary and TFSA results are estimates only; check CRA guidance, your province/territory rules, plan room, lender terms, or professional advice.

Results are estimates only. Do not use this page as regulated financial, tax, legal, payroll, mortgage, or investment advice; check official government sources, provider documents, or a qualified professional before making final decisions.
