The Tax-Calculator simulates the US federal individual income tax system. In conjunction with micro data that represent the US population and a set of behavioral assumptions, the Tax-Calculator can be used to conduct revenue scoring and distributional analyses of tax policies. The Tax-Calculator is written in Python, an interpreted language that can execute on Windows, Mac, or Linux.

This documentation is about developing Tax-Calculator. If you just want to use Tax-Calculator to conduct tax analysis, read this user documentation.

If you are relying on Tax-Calculator capabilities in your own project, be sure to read the definition of the Tax-Calculator Public API.
