This package is not currently in any snapshots. If you're interested in using it, we recommend adding it to Stackage Nightly. Doing so will make builds more reliable, and allow stackage.org to host generated Haddocks.
A library for cash-flow and tax simulations. The type system is used to ensure correctness e.g. of double-entry accounting, and the correct calculation of taxes. The use of Haskell’s
do-notation and type-classes permit an almost verbatim translation of the tax code into the program.
It currently includes personal income tax (Einkommensteuer), corporate tax (Körperschaftsteuer) and trade/business tax (Gewerbesteuer), but could easily be extended to other legal systems
stack runghc -- -isrc src/main
will produce a folder named
html containing the results of the HAX.Example that commes with this library. The look at the full ledger in
html/index.html or the charts
The docs on Hackage are quite comprehensive (with some parts in German).
