What is the difference between Add Tax and Remove Tax?

'Add Tax' calculates tax on the base net price to give the gross total. 'Remove Tax' (Reverse VAT) extracts the pre-tax base price and tax portion from a tax-inclusive total.

What is the standard GST/VAT formula?

To add tax: [Tax = Amount × (Rate / 100)]. To remove tax: [Base = Amount / (1 + (Rate / 100))].
