Usually, in complex accounting software, tax codes are used as a tool to determine the tax treatment of a transaction that has been posted in the software. Normally an account administrator will manually allocate a tax code to each transaction. Once a tax code has been chosen, the treatment of the transaction can be determined, then the system is able to calculate your taxes. Categorising your transactions in ANNA is handy because it can help you quickly and easily organise your business transactions and determine the tax treatment just like a complex accounting system tax code would, but in a much more user friendly and efficient way.
