Tax-Calculator simulates the USA federal individual income and payroll tax system. In conjunction with micro data that represent the USA population, Tax-Calculator can be used to estimate the aggregate revenue and distributional effects of tax reforms under static analysis assumptions. In conjunction with other modules, Tax-Calculator can be used to estimate reform effects under a range of non-static assumptions. 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.
