System and method for generating explanations for year-over-year tax changes

Abstract:

A computer-implemented method for generating an explanation for changes in tax liability over different tax reporting periods includes a computing device executing a tax calculation engine associated with tax preparation software. The tax calculation engine operates on first and second tax calculation graphs representing different tax reporting periods. The first and second tax calculation graphs are different in at least one respect. The first and second tax calculation graphs each describe data dependent tax operations comprising a plurality of interconnecting functional nodes connected by one of a plurality of functions. The computing device automatically identifies the differences among nodes within the respective first and second tax calculation graphs and executes an explanation engine associated with the tax preparation software to generate a textual explanation identifying one or more differences among the nodes.
