Field help: (2022) Identification number

Enter the 11-digit tax identification number (Steuer-Identifikationsnummer) of your divorced spouse / civil partner to whom you are paying maintenance. The identification number always consists of 11 digits.

Your divorced spouse / partner must provide you with the identification number ("IdNr."). He/ she will also find this number in his/her income tax assessment notice (Einkommensteuerbescheid) or in the employment tax statement (Lohnsteuerbescheinigung).

If the tax ID is not available, it can be requested again from the Federal Central Tax Office. The tax ID is then communicated by letter.
