Invoice Generator

GST, HST or GST plus QST — whichever the place of supply calls for, with the CRA's information requirements checked as you type.

The invoice
Sequential, and without gaps. The button under the preview steps it on and keeps the padding, so 0009 becomes 0010 rather than 10.

Terms of payment are one of the CRA's required items on an invoice of $500 or more.
Required on invoices of $100 or more if you are a registrant. Format: 123456789 RT0001.
GST/HST follows the place of supply, not where you are. Ontario is HST at 13%; Alberta is GST alone at 5%; Quebec is GST plus QST as two separate lines.

How this is worked out

Two things have to be right on a Canadian invoice: the tax, and the information your customer needs in order to claim it back.

The tax follows the place of supply, not where you are. Five provinces use a single harmonised tax — Ontario at 13%, New Brunswick, Newfoundland and Labrador and Prince Edward Island at 15%, and Nova Scotia at 14% since 1 April 2025. British Columbia, Saskatchewan and Manitoba charge 5% GST plus a separate provincial sales tax that is not part of the GST system. Alberta and the three territories charge GST alone. Quebec charges 5% GST plus 9.975% QST, as two separate lines, both calculated on the pre-tax amount.

The information requirements step up twice. Under $100 the CRA asks only for your name or trading name, the date, and the total. From $100 your customer also needs the total GST/HST charged — or a statement that the amount includes tax at the applicable rate — and your GST/HST registration number. From $500 they additionally need the buyer's name, a brief description of what was supplied, and the terms of payment.

Those thresholds changed. They were raised to $100 and $500, from $30 and $150, on 20 April 2021. A great deal of published guidance still quotes the old numbers.

Getting this wrong usually costs your customer rather than you: without the required information they cannot claim the input tax credit, so they will ask you to reissue.

Three tax systems in one country

Canada runs three arrangements side by side and an invoice has to reflect the right one. HST is a single combined tax administered federally, so one line at one rate. GST plus PST is two separate taxes with two separate administrations — the PST in British Columbia, Saskatchewan and Manitoba is not part of the GST system at all, and a GST registration does not cover it.

Quebec is the third: GST at 5% plus QST at 9.975%, administered by Revenu Québec, requiring its own registration. Since 2013 QST has been calculated on the pre-GST amount rather than compounded on top of the GST, so the two are additive. That change is old enough that most software has caught up and old enough that a good deal of written guidance has not.

This tool prints whichever lines the place of supply requires, at the rates carried in the site's Canadian tax constants with the CRA's rate page cited beside them.

The $100 line, and why it is the one people miss

Your GST/HST registration number becomes a required item on an invoice of $100 or more. Below that it is optional. That threshold was $30 until April 2021, which is why a lot of accumulated advice — and a good deal of invoicing software — still behaves as though almost every invoice needs it.

The practical effect of leaving it off is not a penalty for you. It is that your customer cannot substantiate their input tax credit, so their bookkeeper sends the invoice back. It is a small, avoidable, slightly embarrassing delay in getting paid.

The panel beside the form shows which tier the current total falls into and which items that tier requires. Change a quantity and watch the requirements change — that is the clearest way to see how the graduated rule works.

Small supplier, and the decision to register early

You must register for GST/HST once your taxable supplies exceed $30,000 over four consecutive calendar quarters. Below that you are a small supplier: registration is optional, you do not charge the tax, and you do not put a registration number on an invoice.

Registering voluntarily below the threshold is common and often sensible, because a registrant can claim input tax credits on business purchases. If your customers are themselves registered businesses, charging them GST costs them nothing — they claim it back — while your own input credits are real money.

If your customers are consumers, the calculation reverses: registering raises your price by the tax or cuts your margin by it. That is a business decision rather than a compliance one, and worth taking with an accountant rather than a calculator.

Why this runs in your browser

An invoice carries your client's legal name, their address, what you did and what you charged. That is commercially sensitive on both sides, and it is exactly the sort of information that should not be handed to a free web service in exchange for a template.

Nothing here is uploaded. The PDF is composed in your browser by a library served from this site, and the page makes no external request of any kind. Open the network tab and check for yourself.

The trade-off is that nothing is stored between visits. Use the copy-link button to keep the invoice in the URL, or export the PDF and keep the file. No account, nothing to delete later.

Canada — information required on an invoice
CRA, "Input tax credits" documentary requirements: under $100, the supplier's name, the date and the total; from $100, also the GST/HST charged (or a statement that the amount includes tax at the applicable rate) and the supplier's GST/HST registration number; from $500, also the buyer's name, a description and the terms of payment. https://www.canada.ca/en/revenue-agency/services/tax/businesses/topics/gst-hst-businesses/calculate-prepare-report/input-tax-credit.html checked 2026-08

QST
QST is administered by Revenu Québec and requires its own registration. The 9.975% rate and the fact that it is calculated on the pre-GST amount are carried in tax/ca-2026.js with their own source line.
Place of supply
The rules for determining the province of supply — particularly for services and intangibles — are more involved than a rate table can express. CRA place-of-supply rules apply.
Not covered
State and local US sales tax rates and taxability, Quebec's mandatory billing rules and QST invoicing requirements, EU cross-border VAT and OSS, e-invoicing mandates, Making Tax Digital, construction industry schemes, and late-payment interest legislation.
Rates current as of 2026 — verify before relying on this. This is a document generator, not tax advice. Place-of-supply rules for services and intangibles are genuinely complicated, and Quebec administers QST through Revenu Québec with its own registration and its own rules.

Questions

What people ask about invoicing in Canada

Do I have to show my GST/HST number on an invoice?

From $100, yes, if you are a registrant — it is one of the CRA's information requirements. Below $100 it is optional. The threshold was $30 until 20 April 2021, so a lot of guidance still quotes the old figure. Leaving it off does not penalise you; it stops your customer claiming their input tax credit.

Which rate do I charge — mine or my customer's?

The rate for the place of supply, which is generally your customer's province rather than yours. An Alberta business invoicing an Ontario customer normally charges 13% HST, not 5% GST. The place-of-supply rules for services and intangibles are more involved than that summary, and worth checking for a cross-border engagement.

When do I have to register for GST/HST?

Once taxable supplies exceed $30,000 over four consecutive calendar quarters. Below that you are a small supplier and registration is optional. Registering voluntarily is common: it costs registered customers nothing, since they reclaim the tax, and it lets you claim input tax credits on your own purchases.

How is Quebec different?

Two lines, not one: 5% GST plus 9.975% QST, with QST administered by Revenu Québec under a separate registration. Since 2013 QST has been calculated on the pre-GST amount rather than compounded on top of it, so the two are additive — on a $4,200 invoice that is $210 plus $418.95.

Why does the invoice number have to be sequential?

Because a numbered series with holes in it invites the question of what was in the holes. A complete sequence is evidence that the ledger is complete; a gap looks like a deleted invoice, and an auditor is entitled to ask you to account for it. If you void one, keep the number and mark it void rather than reusing it or letting it vanish.

Is my client's data sent anywhere?

No. Everything is held in your browser, the PDF is written in your browser, and this site makes no external request of any kind — you can confirm that in your browser's network tab. There is no account, no email gate and no watermark on the file. Your client's name, their address and what you charged them are exactly the things that should not be uploaded to a free web service.
