Of the two ways of using Tax-Calculator described in this guide, one requires writing Python programs, the other involves using a command-line tool and requires no computer programming. The detailed information in this guide about policy parameters, input variables, output variables, and assumption parameters, will be useful to you either way you use Tax-Calculator.
If you want to learn more about how to write Python programs that use Tax-Calculator, follow the Recipes, which contains a collection of tested recipes that employ both basic and advanced techniques.
