GST/HST rates in Canada
Standard rates by province. PST, RST and QST have their own applicability rules; a provincial address alone does not make them payable. Read the GST/HST rates in Canada guide for tax treatment and official sources.

How to calculate GST
Use the sales tax calculator above for an immediate breakdown. To work through the arithmetic, read how to calculate GST and HST by hand.
GST at 5%. $1,000 × 5% = $50 GST. Add it to the price: $1,000 + $50 = $1,050. To remove GST from $1,050, divide by 1.05 to get $1,000 before tax.
Ontario HST at 13%. $1,000 × 13% = $130 HST, so the total is $1,130. To remove HST, divide $1,130 by 1.13: the price before tax is $1,000 and the included HST is $130.
Reverse HST calculator
Starting from a receipt total? Select Remove tax above, or open our reverse HST calculator to find the price before tax and the included tax amounts.
Rounding at different stages can change the last cent. For items taxed at the same rate, CRA allows their prices to be added before the tax is calculated and rounded. Our GST calculation guide explains the arithmetic.
The province selection supplies a rate; it does not determine the legal place of supply. The rules depend on what is supplied and where the supply is made. Read our HST place of supply rules before choosing a rate for an uncertain transaction.
A zero-rated supply is taxable at 0%; an exempt supply has no GST/HST charged. Their treatment for input tax credits differs. Our GST exemption guide explains the distinction; the calculator assumes the selected standard taxes apply.
GST registration
For most unregistered businesses, the $30,000 test decides when registration becomes mandatory. Already registered, or crossed the threshold earlier? Low sales now do not cancel that obligation. Taxi and commercial ride-share drivers register from their first taxable ride.
Read our GST registration guide and the GST income threshold rules before deciding when to register.

GST calculator FAQ
How to calculate GST?
For a sale subject to 5% GST, multiply the price before tax by 0.05. For example, $1,000 × 0.05 = $50 GST, so the price plus GST is $1,050 before any other applicable taxes. See our GST calculation guide for more examples.
How do I calculate HST from a total?
When a total includes only 13% Ontario HST, divide it by 1.13 to find the price before HST, then subtract that price from the total. For example, $1,130 ÷ 1.13 = $1,000 before tax, leaving $130 HST. Use our reverse HST calculator for other amounts.
How to calculate GST and PST?
First check whether GST and PST both apply, then calculate GST on the price before PST and apply the applicable PST rules separately. For example, if both 5% GST and 7% PST apply to a $1,000 before-tax price, GST is $50 and PST is $70, making the total $1,120. Try our GST and PST calculator with the taxes that apply to your sale.
What is the GST rate in Canada?
The GST rate is 5% for standard taxable supplies made in non-participating provinces. For standard taxable supplies in participating provinces, HST applies at the relevant provincial rate; zero-rated supplies have a 0% GST/HST rate. See our GST/HST rates guide for rates by province and territory.
How to register for GST?
Eligible businesses can register for a GST/HST account through CRA Business Registration Online using a CRA account; other registration routes are available when that service cannot be used. Save or print the business number and GST/HST account number during the online session. After registration, filing, charging and remitting responsibilities apply. Read our GST/HST registration guide for the steps.
What is HST in Ontario?
Ontario’s harmonized sales tax combines a 5% federal part and an 8% provincial part for a standard rate of 13%. For a $1,000 sale subject to the full 13% HST, the tax is $130 and the total is $1,130. Read our Ontario HST guide for more detail.
