The tax number (abbreviation: St.-Nr. ) is an ordinal number assigned by the tax office to every taxable natural or legal person under which the person is listed at the tax office. The number is clearly assigned to a taxpayer. The tax number is of central importance for all administrative processes within the tax authorities. There are different tax numbers for many types of tax.
In Germany, the tax number is a code that is used by the tax administration for natural persons and legal entities. The use of tax numbers is provided for in Section 8 of the “Accounting Regulations for Tax Offices” (BuchO). In addition to the tax identification number, there are the following identifiers or identification features ( ):
- the tax identification number was also introduced nationwide for natural persons ( tax code ) from 2008 and is assigned centrally.
- the business identification number for economically active natural or legal persons as well as associations of persons ( tax code ) is assigned by the responsible tax office .
- the sales tax identification number for entrepreneurs within the meaning of the sales tax law (introduced across the EU).
Structure of the tax number
The tax numbers - with the exception of the tax identification number - are composed differently depending on the federal state . A new nationwide scheme has been developed for submitting electronic tax returns using the ELSTER process. The individual schemes are listed below:

In the standard country scheme, the length of the tax number varies between 10 and 11 digits. The federal scheme unifies these to 12 digits. (F) FF represent the last two or three digits of the four-digit federal tax office number (BUFA no.). BBB (B) also stands for the district number within the area of the respective tax office. In North Rhine-Westphalia it was 4 digits, otherwise 3 digits. (U) UUU is the personal distinction number. It was 3-digit in North Rhine-Westphalia, otherwise 4-digit. P is a one- digit check digit . If a 13-digit tax number is required for electronic transmission, a 0 must be inserted between the 4th and 5th digits.
In 2008, a uniform national tax identification number (TIN, Tax Ident Number) was introduced, which remains valid when moving. Contrary to earlier plans, the tax numbers were not abolished, but used in parallel. Based on the tax number, the tax office's post office can identify which area of work in the tax office is responsible.
As of 2003 , the supplier must use his EU tax number ( UID number ) as an invoice feature for deliveries and services carried out in Germany.
Taxable natural as well as legal persons receive their own tax number from the tax office, under which all tax activities are saved and managed.
- the numeric country code 756 for Switzerland according to the standard ISO 3166 -1
- a nine-digit, personal, "non-speaking" number as well
- a check digit ( EAN-13 ).
In Spain the following tax numbers are distinguished:
- Número de Identificación Fiscal (NIF) - tax number for residents
- Número de Identificación de Extranjeros (NIE) as a tax number for foreigners.
There is no distinction between tax number and sales tax identification number . The NIF combines both. In the past there was also the name CIF - Código de Identificación Fiscal . The NIF applied to individuals and the CIF to corporations. Today these are both officially called NIF. The term CIF is still used in Spain. The structure of the NIF also differs depending on its use for individuals or companies.
In Italy, the tax number (codice fiscale) includes the surname and first name, date of birth (+ gender), place of birth and verification number. Example: "MST MXA 90L01 F205 F" (Max Mustermann, July 1, 1990, Milan). Men are assigned the digits of the date of birth without change; Women add 40 to the number of days (so, for example, July 1, 1990 for women returns 90L41).
To calculate the Italian tax number there are e.g. B. a service.
The electronic citizen card enables digital communication with the Italian tax administration.
European TIN portal
Since most EU countries use Tax Identification Numbers (TINs) to distinguish taxpayers and to simplify national tax administration, the EU Commission published:
- Information about TINs of the EU member states, including descriptions of the structures and characteristics of national TINs, examples of official documents containing TINs, and national contact points that have been approved for publication.
- an online checking module that checks the TIN syntax (the algorithm) or, if this is not available, the TIN structure.
There is currently no TIN at EU level. Some countries do not automatically assign a TIN to taxpayers. The online verification module does not verify a person's identity or confirm the existence of a TIN. It is checked whether the syntax (the algorithm) and / or the structure of the TIN is correct. If a country did not provide any algorithms, only the structure is checked.
