In Ontario, the sales tax takes the form of the HST (Harmonized Sales Tax) at 13%. It is a single tax that combines the federal (5%) and provincial (8%) portions, administered by the Canada Revenue Agency. Canada (CRA). Unlike the dual-tax system in some provinces, Ontario does not add a separate provincial tax: a single rate of 13% applies. The calculator above applies this 2026 rate by default. Understanding how it works is essential for correctly invoicing and reclaiming taxes paid on your business purchases.
The HST is applied as a percentage of the subtotal before tax: in Ontario, 13% is added to the price before tax to arrive at the total. Since it is a single harmonized tax, there is no separate calculation between the federal and state levels on your invoice: the combined rate of 13% is applied once. The calculator uses this exact rate and applies it automatically, preventing rounding errors on your invoice.
A taxable sale (the majority of sales) is charged at the full HST rate of 13% in Ontario. A zero-rated sale is charged at 0%, but the business can usually reclaim the tax paid on related purchases. An exempt sale carries no tax, and the business cannot reclaim the tax paid on related inputs. Ontario also offers point-of-sale rebates on certain goods (children's clothing, books, prepared food items under $4, among others), for which the provincial portion of the HST is deducted.

Enter your total amount including tax and specify that the tax is already included: the tool calculates the subtotal excluding tax by dividing by 1.13 (the combined Ontario sales tax rate), then isolates the HST amount. In Ontario, since the tax is harmonized, only one tax is extracted. Our calculator performs these extractions automatically.
In Ontario, a business must register for and collect HST once its taxable sales exceed $30,000. Once registered, it charges HST to its customers, files periodic returns, and remits the net tax to the CRA. An accountant can confirm your obligations based on your business and circumstances.
In Ontario, HST registration becomes mandatory once taxable sales exceed $30,000 for four consecutive quarters; below this threshold, the business is considered a small supplier. Below the threshold, businesses generally do not charge HST, but they also cannot reclaim the HST paid on their purchases. Voluntary registration remains an option to reclaim these taxes.
A registered business can deduct the VAT it paid on its business expenses from the VAT it collected on its sales, and then remit the difference to the IRS (or receive a refund if it is negative). In Ontario, this recovery is facilitated by input tax credits (ITCs).
