How sales tax works in Ontario
Ontario uses the harmonized sales tax (HST), one 13% tax instead of separate federal and provincial taxes. Ontario's Ministry of Finance describes it as the 5% federal GST combined with an 8% provincial part.
The Canada Revenue Agency administers and collects the HST on Ontario's behalf, so there is no provincial sales tax account to open. A frequent mistake on Ontario invoices is listing 5% GST and 8% PST as two taxes. In Ontario they are a single 13% HST line.
Who has to register and charge it
You must register once you are no longer a small supplier. The CRA's test is $30,000 in taxable sales: go over it in a single calendar quarter, or over four consecutive calendar quarters, and you have to register and charge 13%. Our guide on how to register for GST/HST covers the steps.
Self-employed taxi and commercial ride-sharing drivers are the main exception, since they must register even below $30,000. For what an Ontario invoice should show once you are registered, see our contractor invoice requirements guide.
Selling to customers outside Ontario
The rate follows the place of supply, not where your business sits. Under the CRA's place-of-supply rules, goods are generally taxed where they are delivered and most services where the customer's address is. A Toronto shop shipping to Calgary charges 5% GST, and an Ottawa consultant billing a Halifax client charges 14% HST.
Customers in British Columbia, Saskatchewan, Manitoba and Quebec also have provincial taxes with their own registration rules. Check the rates by province guide before invoicing them, and the US clients guide for sales outside Canada.
Frequently asked questions
Is HST 13% or 15% in Ontario?
HST in Ontario is 13%, made up of a 5% federal part and an 8% provincial part. The 15% rate applies in New Brunswick, Newfoundland and Labrador and Prince Edward Island, and Nova Scotia is 14%.
How do I remove HST from a total in Ontario?
Divide the HST-included total by 1.13. For example, $113 divided by 1.13 is $100, so the HST portion is $13.
Is there PST in Ontario?
No separate PST is charged in Ontario. The provincial share is the 8% part of the 13% HST, which the CRA collects for the province.
Do I charge HST to a customer in Alberta?
Goods shipped to Alberta are generally taxed at 5% GST, not 13% HST, because goods follow the delivery address. Most services follow the customer's address, so an Alberta client usually means 5% GST as well.
When do I have to start charging HST?
Once your taxable sales pass $30,000 in a single calendar quarter or over four consecutive calendar quarters, you are no longer a small supplier and must register with the CRA.
