Frequently asked questions
What is the difference between add tax and extract tax?+
Add tax multiplies a net amount by the tax rate to get gross. Extract tax divides a tax-inclusive total to find the net amount and tax portion.
Which currencies are supported?+
Display symbols include USD, GBP, EUR, and others. The calculator performs math only — it does not convert exchange rates.
Can AutoDocParse read tax from invoices?+
Yes. Invoice and receipt parsers extract subtotal, tax rate, tax amount, and total from uploaded documents.
