Sales tax in Ontario
Ontario charges the harmonized sales tax (HST) at 13%: one combined tax that replaces the 5% GST and the provincial sales tax, collected and administered by the Canada Revenue Agency.
Single 13% HST (5% federal + 8% provincial).

When to register: the small supplier threshold
Small supplier: worldwide taxable supplies (with associates) of $30,000 or less over four consecutive calendar quarters; registration optional. If $30,000 is exceeded in a single quarter, register immediately (from the supply that crossed it). Public service bodies: $50,000.
Filing frequency
Assigned GST/HST reporting period by annual taxable supplies: $1.5M or less = annual; over $1.5M up to $6M = quarterly; over $6M = monthly. More frequent filing can be elected. Monthly/quarterly returns due 1 month after period end; annual 3 months after fiscal year-end (individuals with Dec 31 year-end and business income: file by June 15, pay by April 30).
What a GST/HST invoice must show
The information required on a GST/HST invoice or receipt depends on the amount:
- Under $100: supplier's business or trading name (or intermediary's), invoice date (or date GST/HST paid or payable), total amount paid or payable.
- $100 to $499.99: all of the above plus the supplier's GST/HST registration number, the total GST/HST charged (or a statement that the price includes GST/HST at the applicable rate), and the status of each supply when taxable and exempt items are mixed.
- $500 or more: all of the above plus the buyer's name or trading name (or authorized agent), a brief description of the goods or services, and the terms of payment.
How the calculation works
Adding tax multiplies the price by each rate separately and adds the results; GST, PST and QST are never charged on each other. Removing tax divides the total by (1 + combined rate) to find the price before tax, then splits the tax back into its parts.
Frequently asked questions
What is the sales tax rate in Ontario?
The combined rate is 13%. The calculator on this page shows how it splits between the federal and provincial parts.
How do I remove sales tax from a total in Ontario?
Divide the total by 1 plus the combined rate (13%), or choose "Remove sales tax" above: the calculator shows the price before tax and each tax separately.
Who collects the sales tax in Ontario?
Registered businesses collect it from their customers and remit it with their returns: GST and HST to the Canada Revenue Agency, and a separate provincial tax to the province (Revenu Québec for QST).
Do I have to register if my business is small?
Not for GST/HST until your taxable sales pass 30,000 dollars over four consecutive calendar quarters. Provincial sales taxes have their own registration rules, so check them separately.
When does a business have to register for GST/HST?
When its taxable sales pass 30,000 dollars over four consecutive calendar quarters (the small supplier threshold), or immediately if they pass it in a single quarter.
Is PST charged on GST?
No. In every province with a separate provincial tax, the provincial tax is calculated on the price before GST, so the rates simply add up.
