Currently the VAT reports pull from the TX30000 tax table and reports are generated in the functional currency ID. (While most users are on a UK install and have GBP as their functional currency, this won't be a problem with the new digital tax filing requirements. ) However, you can install VAT on a U.S. install, in which GBP would not be your functional currency. With the new digital tax requirement, will there be an option to file in a multi-currency ID so you can still file from a U.S. install?
