Invoice calculator with GST/HST

List what you are billing, mark which lines are taxable, pick the province where the sale is taxed, and copy a clean summary with each tax line.

Province or territory of the sale
Invoice lines
Invoice total-
Tax is worked out once on the sum of the taxable lines, not line by line, using the rates in force on April 1, 2025 from the CRA table. It does not cover tax-exempt or zero-rated rules, rebates, discounts, small supplier status or Quebec and BC registration.

What the invoice must show

The CRA publishes what a buyer needs on an invoice to claim input tax credits. A seller who is a GST/HST registrant should include these items, which depend on the invoice total.

Frequently asked questions

Which tax do I charge?

It depends on the province where the sale is taxed: HST in Ontario and the Atlantic provinces, GST only in Alberta and the territories, and GST plus PST or QST in British Columbia, Manitoba, Saskatchewan and Quebec. The calculator shows the lines for the province you pick.

Why is tax worked out on the total and not on each line?

Taxing the sum of the taxable lines avoids rounding each line separately and matches how an invoice total is normally taxed. A line-by-line method can differ by a cent or two.

How do I show a line with no tax?

Untick Taxable on that line. It is added to the total without tax. Whether a supply is exempt or zero-rated is for you to decide using the CRA rules; the page does not decide it for you.

What information does an invoice need?

The CRA table on this page says what is required at each amount: for $500 or more, the supplier’s name, the date, the total, the tax charged, the registration number, the buyer’s name, a description and the payment terms.

Does this page file anything?

No. Nothing is sent or stored. The summary stays in your browser until you copy it.

How we check

The tax lines come from the same calculation as our GST/HST calculator, which is compared with the CRA rate table. The tests also check the invoice total against that calculation for all 13 provinces and territories, the line arithmetic against hand-worked cases, and the CRA invoice-information thresholds ($100 and $500) against the CRA input tax credit page.

Limits: the CRA page publishes no worked invoice example, so the invoice totals are compared with our own tax calculation and hand arithmetic, not with an official calculator. Rebates, discounts, exempt and zero-rated status, small suppliers and Quebec QST rules are not modelled. This page is not legal or tax advice.
