When to use this template
Use this template if you're invoicing from Ontario or invoicing an Ontario-based client and are HST-registered. Ontario is one of the harmonized-tax provinces — instead of charging GST and PST separately, you charge a single 13% HST that combines the federal 5% GST and provincial 8% portion. The HST gets reported and remitted on a single CRA return (the GST/HST return), unlike Quebec which requires separate GST and QST returns. The template includes the place-of-supply field because the rate that applies is determined by where your client is located, not where you are.
Ontario HST invoicing essentials
Three things every Ontario HST invoice must include: your HST registration number (the 9-digit business number followed by RT0001, which is the GST/HST account identifier), the HST charged shown as a separate line (not buried in the line item totals), and a clear statement of which province's rate applies. For Ontario-to-Ontario invoices, the 13% HST rate is straightforward. For Ontario-to-other-province invoices, the customer's province rate applies under place-of-supply rules — if you're invoicing a BC client from Ontario, you charge 5% GST (not 13% HST), and you'd typically also need to separately handle BC PST if the client is consuming the service in BC. The template's province field makes this explicit. Verify Ontario HST rates at canada.ca before sending — Ontario has held at 13% since 2010 but rates do occasionally change.
Common Ontario invoicing mistakes
The most common mistake on Ontario invoices is omitting the HST registration number when the business is registered. The CRA can disallow input tax credits on the receiving end if the number is missing, which causes your client to push back on the invoice. The second most common mistake is bundling HST into line item totals instead of showing it separately — CRA requires it to be clearly identified. The third mistake: charging HST when you shouldn't be registered (revenue under $30K), which creates problems both for your own returns and for your client's input tax credit claims.

Questions, answered
Frequently asked questions
What is the HST rate in Ontario?
Ontario's HST rate is 13% — 5% federal GST + 8% provincial portion combined into a single harmonized rate. This has been Ontario's rate since the HST was introduced in 2010. Unlike BC or Saskatchewan where you charge GST and PST separately, Ontario uses a single combined HST line on invoices. The full 13% is reported and remitted to CRA on a single GST/HST return.
Do I need to be HST-registered to send invoices in Ontario?
Not below the $30,000 small supplier threshold. If your taxable revenue is under $30,000 across any rolling four quarters, you're a small supplier and don't charge HST — but you also can't claim input tax credits on business expenses. Above the threshold, registration is mandatory. Many Ontario freelancers register voluntarily before they hit the threshold so they can claim input tax credits on software, equipment, and other business costs.
What is RT0001 on my HST registration number?
RT0001 is the four-character account identifier for your GST/HST program account, following your 9-digit Business Number. The full format is XXXXXXXXX RT0001 (e.g., 123456789 RT0001). The 'RT' indicates GST/HST (as opposed to RP for payroll or RC for corporate income tax), and 0001 is your first GST/HST account — most businesses only ever have one. Always show the full 15-character registration number on Ontario HST invoices.
Do I charge Ontario HST to clients in other provinces?
No — under place-of-supply rules, you charge the rate of the client's province, not yours. To a BC client: 5% GST (and you'd separately handle BC PST if applicable). To a Quebec client: 5% GST + 9.975% QST. To an Alberta client: 5% GST only. To another Ontario client: 13% HST. For international clients, services are generally zero-rated. The template's province field lets you set the correct rate per client.
