What is the difference between including and excluding tax?
Excluding tax (Add Tax) means you start with a base price and add the tax on top, which is common in the US and Canada. Including tax (Remove Tax) means you start with the final shelf price and work backward to find out how much of that total was actually tax—a common requirement in many European and Commonwealth countries using VAT or GST.
Can I use this for international taxes like GST or HST?
Yes! While names differ by country, the math remains the same. Whether it's VAT in the UK, GST in Australia, or HST in Canada, just enter the relevant percentage for your region. Our tool provides a high-precision breakdown regardless of the tax's official name.
Is there a limit on the number of tax calculations I can perform?
None whatsoever. We believe essential tools for commerce should be free and accessible without barriers. You can run as many calculations as you need, refresh the results instantly, and copy the breakdown for your records or invoices without any cost or registration.
