Frequently asked questions
What rates are included?
A list of common regional VAT and GST rates, plus the option to enter any custom percentage.
What's the difference between adding and extracting VAT?
Adding VAT starts from a net (tax-excluded) amount and calculates the tax-inclusive total; extracting VAT starts from a gross (tax-included) amount and works out how much of it was tax.
Is this accurate enough for official filings?
It performs the standard percentage calculation correctly, but always confirm the applicable rate and any special rules with your local tax authority or accountant for official use.
