detax 0.1

German income tax library

This is an experimental package, allowing the calculation of income tax rates in Germany (useful for freelancers, since they usually pay tax once per year only, resulting in a substantial amount owed).

The package is fairly incomplete, but can be used as a starting point; bug reports, feedback and pull requests are very welcome.

CLI

While being usable as a library, the package comes with an optional CLI. To use it, the click package must be installed as well:

$ detax --help
Usage: detax [OPTIONS] INCOME

Options:
  -y, --year INTEGER          Tax year
  -c, --church-tax [rk|ev]
  -s, --state TEXT
  -p, --perc / -P, --no-perc  Show total tax percentage
  --help                      Show this message and exit.
