Abstract: A method of assigning tax codes for a transactional document such as a list of items in a shopping cart. This method is a configurable solution without making changes to the application code. A series of questions are directed to an end user. Depending on the tax requirements of a country, the questions are tailored in a language understandable to the user. From these questions, possible answers are collected, and translated to a set of indicators. These indicators are mapped to tax codes that can be assigned to a transactional document listed in a shopping cart.
