Questions about sales tax calculator

Can it handle two taxes?

Yes. Enter both rates, for example GST and PST, and they are combined.

How does "remove tax" work?

It finds the price before tax that, with tax added, equals the total you entered.

Is my information private?

Yes. It is worked out on your device.

Adding and removing tax

To add tax, enter the price before tax and the rate. To work backwards, enter the total you paid and choose remove tax, and the tool finds the price before tax that gives that total. For example, 100 with a 5 percent tax and a 7 percent tax becomes 112, and removing tax from 112 at the same rates returns 100.

When a place has two taxes, such as GST and PST in some Canadian provinces, enter both rates. The tool adds them together and applies the combined rate to the price before tax.

Know your local rules

Tax rates and what is taxable differ between countries, states and provinces, and some items are exempt. This tool does the arithmetic with the rates you enter, so check the right rate for your location and the item. For anything official, such as a tax return or a business invoice, confirm the figures with the tax authority or an accountant.
