In Canada, one or two sales taxes are added to the price of most goods and services: the federal tax (GST) and, depending on the province, a separate provincial tax (the QST in Quebec, the PST or RST elsewhere) or a single harmonized sales tax (HST). The calculator above applies the 2026 rates for the province you select. Understanding how these taxes work is essential for billing correctly and, where applicable, claiming back taxes paid on your business purchases.
The principle is the same everywhere: the tax is applied as a percentage of the pre-tax subtotal. When multiple taxes apply (for example, a federal tax and a provincial tax), each is calculated based on the pre-tax subtotal and then added to the final price. The calculator uses the exact rate for the selected jurisdiction and applies it automatically, which prevents rounding errors in your invoicing.
A zero-rated sale is charged at 0%, and the business can generally recover the taxes paid on related purchases. An exempt sale is not subject to any tax…

Enter your total amount (including taxes) and specify that the tax is already included: the tool calculates the subtotal excluding taxes by dividing by the combined tax rate for the selected jurisdiction, then breaks down each tax. When multiple taxes apply, it lists them separately. Our calculator performs these calculations automatically.
In Canada, the requirement to register and collect tax depends on the province and, often, on a revenue threshold (for example, $30,000 for GST and HST). Once registered, the business charges the tax to its customers, files periodic returns, and remits the net tax to Revenu Québec or the CRA. An accountant can confirm your obligations based on your business activity and province.
…(below this threshold, the business is considered a small supplier); the QST follows the same $30,000 rule in Quebec.
A registered business can deduct the tax it paid on business expenses from the tax it collected on sales, and then remit the difference to the government (or receive a refund if the amount is negative). In Canada, these are known as input tax credits (ITCs) for the GST and HST, and input tax refunds (ITRs) for the QST.
