Frequently asked questions
What is the difference between add and remove?
Add tax treats your amount as net (tax-exclusive) and adds the tax on top; remove tax treats it as gross (tax-inclusive) and works back to the net amount.
How is tax removed from a gross price?
The net is the gross divided by 1 plus the rate, so for 20% the net is gross ÷ 1.20 and the tax is the difference.
