Abstract: One embodiment of the present invention provides a system that implements a tax service that is configurable for local jurisdictions by an expert in the field, such as a tax professional, who may have little or no knowledge of computer programming. The system operates by receiving a request from a subscriber, wherein servicing the request involves calculating taxes for one or more local jurisdictions. Tax rules for a local jurisdiction can be fed into a tax rule base that is used by a tax engine that is configured to use these externally specified rules in performing tax computations. Next, the system uses the tax engine to calculate taxes for each local jurisdiction, and subsequently uses the results of the calculations in servicing the request.
