Business Identification Number; Application

When you start an economic activity, you will be provided with a business identification number (W-IdNr.).

Description

In the future, the Federal Central Tax Office (BZSt) will assign a business identification number (W-IdNr.) to each economically active person in addition to the tax identification number (IdNr.).

Tax authorities are thus able to correctly assign economically active legal entities to the natural persons acting in each case.

The W-IdNr. will consist of the letters 'DE' and 9 digits and thus correspond in its form to the value added tax identification number (USt-IdNr.).

The BZSt will issue a W-IdNr. at the request of the competent tax authority and notify you without you having to submit an application.

Note:
The W-IdNr. is currently not yet issued. Information will be made available to you in good time before it is introduced.

Prerequisites

The business identification number (W-IdNr.) is issued to:

  • natural persons who are economically active
  • legal entities
  • associations of persons

Procedure

The Federal Central Tax Office (BZSt) will issue a business identification number (W-IdNr.) at the request of the relevant tax authority and inform you; you do not need to submit an application yourself.

Note:
The W-IdNr. is currently not yet issued. Further information will be made available in good time before it is introduced.
