Steuer-ID

Validates the German Tax-ID (Steuerliche Identifikationsnummer, short: Steuer-ID) using Python.

Based on the official ELSTER documentation (chapter: 2).

Note

This package validates solely the syntax and check digit of the provided input. It does not confirm, that the validated Steuer-ID was assigned to a person. Please contact the Bundeszentralamt für Steuern in case you are unsure about your Steuer-ID.

Usage

An example of how it can be used:

from steuerid import SteuerId

validation_result = SteuerId.validate("02476291358")

print(validation_result) # (True, None) -> the provided input is a valid steuer id

validation_result = SteuerId.validate("x1234567890")
print(validation_result) # (False, OnlyDigitsAllowedException) -> invalid input, only digits are allowed

Test-Steuer-IDs

Support for test Steuer-IDs (starting with 0) is enabled by default. Test Steuer-IDs are typically invalid in production. It is recommended to disable them with the following environment variable:

STEUERID_PRODUCTION=true
