In Alberta, the calculator applies the only tax added to the price: the 5% federal GST. No provincial sales tax is added. You can also select another province or territory from the menu if needed.
View the subtotal, the 5% GST, and the total including tax, ready to use on your Alberta invoices.
Understanding how it works helps you bill correctly and, if your business is registered, claim back the GST paid on your business purchases.
The principle is simple: the 5% GST is applied as a percentage of the pre-tax subtotal. Since Alberta has no provincial sales tax, this is the only tax to be added, making the calculation much simpler than in provinces with two tax rates. The calculator uses the exact 5% rate and applies it automatically, preventing rounding errors in your invoicing.
A zero-rated sale is charged at 0%, and the business can generally recover the GST paid on related purchases. An exempt sale is not subject to any tax…

In Alberta, the 5% GST is the only sales tax; there is no provincial sales tax. Official source: Canada Revenue Agency (CRA), rates effective in 2026.
Certain categories of goods and services may be zero-rated or exempt under federal GST rules.
Enter your total amount (including tax) and specify that the tax is already included: the tool calculates the subtotal excluding tax by dividing by 1.05 (the 5% GST in Alberta), then isolates the tax amount. Since there is only one tax to account for, the calculation is straightforward. Our calculator performs this calculation automatically.
In Alberta, the requirement to register for and collect GST depends on a taxable sales threshold of $30,000. Once registered, the business charges its customers the 5% GST, files periodic returns, and remits the net tax to the Canada Revenue Agency (CRA). An accountant can confirm your obligations based on your business activities.
Registration for the GST becomes mandatory once taxable sales exceed $30,000 over four consecutive quarters. Below that threshold, the business is considered a small supplier: it generally does not charge GST, but also cannot claim a refund for the GST paid on its purchases. Voluntary registration is still an option to claim these taxes. This rule applies across Canada, including Alberta.
Yes. An Alberta business registered for the GST can deduct the GST it paid on its business expenses from the GST it collected on its sales, and then remit the difference to the CRA (or receive a refund if the amount is negative). These are called input tax credits (ITCs), which allow businesses to recover the 5% GST paid on business purchases.
