Free GST Invoice Template for Canada

Free GST Invoice Template for Canada

A GST invoice template for a Canadian business is more than a billing document. It is a tax record that determines whether your customer can claim an input tax credit and whether your own GST/HST filings hold up under CRA review. Getting the format right is essential.

This guide walks through the GST-specific requirements for Canadian invoices, how to structure tax lines correctly, and how to build a template that works in every province and territory.

CRA Requirements for GST/HST Invoices

The Canada Revenue Agency sets specific rules for the information that must appear on an invoice for your customer to claim an input tax credit. The required fields scale with the invoice amount.

For invoices under $30 total, you must include your business or trading name, the date of the invoice, and the total amount paid or payable. The GST/HST status must be indicated, either as a percentage rate or as a statement that GST is included.

For invoices from $30 to under $150 total, you add your GST/HST registration number and the amount of GST/HST charged or a statement that it is included along with the rate.

For invoices of $150 or more, you must additionally include the customer's name or trading name, the terms of payment, and a description of each item or service supplied.

Most professional invoices should include all fields regardless of amount for consistency. Customers prefer a complete invoice every time, and your records are cleaner.

If you are a GST/HST registrant, your registration number must appear on the invoice. The format is a 15-character business number followed by RT followed by four digits for the GST/HST program account. Showing only part of the number, or omitting it entirely, can prevent your customer from claiming their input tax credit.

For invoices issued under the simplified accounting method, the rules are slightly different but generally similar. Check CRA guidance for your specific accounting method if you have selected one.

GST Rates Across Canadian Provinces and Territories

Canada has a layered sales tax system that varies by province and territory. Your invoice must reflect the correct combination based on where the supply is delivered.

The federal Goods and Services Tax (GST) is 5 percent and applies across all of Canada. Some provinces have harmonized their provincial sales tax with the federal GST into a single Harmonized Sales Tax (HST).

HST applies in five provinces. Ontario charges HST at 13 percent. New Brunswick, Newfoundland and Labrador, Nova Scotia, and Prince Edward Island all charge HST at 15 percent. On an invoice to a customer in any of these provinces, you show a single HST line.

Three provinces administer a separate Provincial Sales Tax (PST) alongside the federal GST. British Columbia charges 5 percent GST plus 7 percent PST. Saskatchewan charges 5 percent GST plus 6 percent PST. Manitoba charges 5 percent GST plus 7 percent Retail Sales Tax (RST), which functions as their PST. On invoices to customers in these provinces, you show GST and PST/RST on separate lines because they are administered by different authorities.

Quebec uses its own Quebec Sales Tax (QST) at 9.975 percent on top of the federal 5 percent GST. QST is administered by Revenu Quebec, not the CRA. On invoices to Quebec customers, you show GST and QST on separate lines and you must have a QST registration number if your taxable supplies in Quebec exceed certain thresholds.

Alberta, Yukon, Northwest Territories, and Nunavut have no provincial sales tax. Invoices to customers in these jurisdictions show only the 5 percent GST.

The place of supply rules generally determine which province's tax applies. For most goods, it is where the goods are delivered. For most services, it is where the customer normally receives the service. Get this right by capturing the customer's address accurately at invoicing time.

GST Invoice Calculation and Display

The way you display GST on an invoice depends on which province your customer is in. Here are model layouts for each situation.

For an HST province like Ontario, your invoice might show: Subtotal $1,000.00, HST 13 percent $130.00, Total $1,130.00.

For a GST-only jurisdiction like Alberta, your invoice shows: Subtotal $1,000.00, GST 5 percent $50.00, Total $1,050.00.

For a PST province like British Columbia, your invoice shows two separate tax lines: Subtotal $1,000.00, GST 5 percent $50.00, PST 7 percent $70.00, Total $1,120.00.

For Quebec, your invoice shows: Subtotal $1,000.00, GST 5 percent $50.00, QST 9.975 percent $99.75, Total $1,149.75. Note that QST is calculated on the pre-tax amount, not on GST-inclusive amount (this rule was changed many years ago).

Some supplies are zero-rated. Examples include basic groceries, prescription drugs, and most exports. On a zero-rated invoice, show the GST/HST line as 0 percent and indicate that the supply is zero-rated. Zero-rated suppliers can still claim input tax credits on related expenses.

Other supplies are exempt, meaning no GST/HST applies and the supplier cannot claim input tax credits. Examples include most health care, education, and financial services. On an exempt invoice, do not show a GST/HST line. State that the supply is exempt under the relevant section of the Excise Tax Act if helpful.

For mixed invoices containing both taxable and zero-rated or exempt items, clearly identify which line items fall into which category.

Place of Supply Rules and Cross-Border Sales

Determining the correct tax rate requires understanding the place of supply. For Canadian sales, the rules are generally straightforward but have nuances.

For most tangible goods, the place of supply is where the goods are delivered. A seller in Alberta shipping to a customer in Ontario charges Ontario HST at 13 percent, not Alberta GST only.

For most services to individual consumers, the place of supply is generally where the recipient normally lives. For services to business customers, the place of supply is where the customer is located based on their business address.

For digital products and subscriptions to consumers, the place of supply is generally the customer's home address. For SaaS, online courses, and digital downloads, capture the customer's address and apply the appropriate rate.

For sales to customers outside Canada, supplies are generally zero-rated as exports. Goods physically exported and services performed primarily for customers outside Canada both qualify, with specific documentary evidence requirements. Mark the invoice with text like Zero-rated supply, export to indicate the treatment.

For sales from outside Canada into Canada, GST may apply through the registered non-resident GST regime, the marketplace facilitator rules, or import GST collected at the border. The rules depend on whether the seller has a registered presence in Canada.

Get the place of supply right because the wrong rate creates problems on both sides. Your customer cannot claim their input tax credit at a rate you did not charge, and you owe the correct rate to the CRA regardless of what you collected.

Filing GST/HST Returns and Record Keeping

Once registered for GST/HST, you must file returns periodically. The frequency depends on your annual taxable supplies. Businesses with annual supplies under $1.5 million file annually. Businesses between $1.5 million and $6 million file quarterly. Businesses over $6 million file monthly. You can also choose to file more frequently than required.

For each filing period, you calculate the GST/HST collected on your taxable supplies and the GST/HST you paid on business inputs (your input tax credits). You remit the net amount to the CRA, or claim a refund if your input tax credits exceed your collected tax.

Keep all invoices issued and received for at least six years from the end of the related tax year. The CRA can audit GST/HST records during this period, and missing or incomplete invoices create assessment risk.

Use an accounting platform that integrates with your invoicing tool to make filing accurate and fast. Eonebill.ai exports GST/HST data in formats compatible with most Canadian accounting software including QuickBooks Online, Xero, and Wave.

For PST and QST, separate filing is required with the relevant provincial authority. PST and QST filings have their own frequencies and rules.

The practical reality of multi-province GST is that errors compound over time. A business that miscategorises supplies for a single quarter might face a small assessment. A business that miscategorises for two years faces a much larger assessment plus interest plus penalties. Catching and fixing errors early is the difference between a manageable correction and a serious financial event. Reconcile your GST/HST collected and claimed each filing period rather than waiting until year-end, and the corrections stay small.

For Canadian businesses that have grown across provincial lines, the question of permanent establishment can become important. Having physical presence, employees, or significant activity in a province can create tax obligations beyond just sales tax, including provincial income tax filings. The rules differ by province and can be nuanced for service businesses. If your operations are growing into new provinces, consult a Canadian tax professional to confirm your obligations. The cost of a one-hour consultation is much less than the cost of discovering an unfiled tax obligation later.

Another consideration for service businesses is whether to register voluntarily for GST/HST below the threshold. Voluntary registration allows you to recover input tax credits, but it also requires you to charge GST/HST to all customers, which can make your prices appear higher to consumers and small businesses that are not GST registered. The tradeoff depends on your customer mix. If most of your customers are GST-registered businesses, voluntary registration is usually beneficial because the tax flows through and your business expense recovery is meaningful. If most of your customers are consumers or unregistered businesses, voluntary registration may put you at a price disadvantage. Run the numbers before deciding.

Finally, for Canadian businesses considering an eventual sale or merger, clean GST/HST records are essential during due diligence. Buyers will look closely at your tax compliance, including whether you correctly classified supplies, applied the right rates, and remitted on time. A clean compliance record supports a higher valuation. A messy record creates uncertainty that buyers price as risk. The discipline you maintain in your invoicing system today contributes directly to the value you can extract from your business years from now.

For Canadian businesses operating across multiple provinces or with significant cross-border activity, the complexity of GST/HST compliance can become substantial. Many businesses at this stage benefit from working with a CPA or tax advisor who specialises in Canadian indirect tax. The advisor can review your invoicing setup, confirm correct place-of-supply treatment, identify recovery opportunities, and prepare you for any CRA inquiry. The annual cost is modest compared to the risk reduction and tax savings it produces. Eonebill.ai's compliance reporting makes the advisor's work straightforward by providing organized data exports they can analyse efficiently.
