About this tool
In add-tax mode, the tax is the net amount multiplied by the rate divided by 100, and the gross total is net plus tax. In remove-tax mode, the net amount is the gross amount divided by one plus the rate as a decimal, and the tax is gross minus net. Use the rate that applies in your situation.
Frequently asked questions
What is the difference between add and remove tax?
Add tax starts from a price without tax and adds it on. Remove tax starts from a price that already includes tax and works backwards to the price without tax.
Why is removing tax not just subtracting the percentage?
Removing tax divides by one plus the rate, because the percentage was applied to the smaller net amount, not to the gross amount.
