Tax law is a particular application well-suited for an expert system because of the large among of knowledge and the many variables involved. The following presents the results of implementing a small portion of tax code, with a brief look at whether or not it can be fully recreated in an accurate system with an acceptable response time. The actual prototype implementation has been done using the expert shell NEXPERT, making use of the IF/THEN rule construct which seems to fall naturally from the tax code.
