How to calculate GST and HST

Adding tax to a price

Tax = price × rate ÷ 100   |   Total = price + tax

Example: $250 in Ontario with 13% HST → tax = $32.50, total = $282.50. In Quebec, GST is $12.50 and QST is 9.975% × $250 = $24.94, for a total of $287.44. Both taxes are calculated on the pre-tax price; QST is no longer charged on top of GST.

Reverse sales tax: finding the price before tax

Price before tax = total ÷ (1 + rate ÷ 100)

Example: a receipt of $113 in Ontario → 113 ÷ 1.13 = $100 before tax, so the HST was $13. Taking 13% of $113 ($14.69) would overstate the tax.

Do businesses have to charge GST/HST?

Businesses must register for GST/HST once their taxable sales exceed $30,000 over four consecutive calendar quarters (the small supplier threshold). Registered businesses charge tax on their sales and claim input tax credits for the GST/HST they pay on business purchases.

Frequently asked questions

How do I calculate HST in Ontario?

Multiply the price by 0.13 for the tax, or by 1.13 for the total. $80 plus 13% HST is $80 × 1.13 = $90.40, of which $10.40 is HST.

How do I remove GST/HST from a total?

Divide the total by 1 plus the rate. With 13% HST: $90.40 ÷ 1.13 = $80 before tax. With 5% GST only: $105 ÷ 1.05 = $100.

What is the sales tax in Quebec?

5% GST plus 9.975% QST, for a combined 14.975%. Both are calculated on the price before tax.

Which provinces have HST?

Ontario (13%), Nova Scotia (14%), New Brunswick, Newfoundland and Labrador and Prince Edward Island (15%).

Which province has the lowest sales tax?
