Introduction
The tax identification number (Steueridentifikationsnummer or tax ID) is an 11-digit number assigned to every person who lives in Germany or is liable to pay taxes there. This number is unique to each person and remains the same throughout their entire life – even if they move to another place within Germany or change jobs.
When is the tax identification number issued?
The tax identification number is issued when a person is registered for the first time as a resident in Germany. Newborn children receive their tax ID shortly after birth.
The number is sent by post to the registered address by the Federal Central Tax Office (Bundeszentralamt für Steuern).
Why is the tax identification number important?
The tax identification number (Steueridentifikationsnummer) is used in all communication with the tax authorities regarding tax matters. You must provide this number in many situations, such as:
when filing your annual tax return (Steuererklärung)
when dealing with the tax office to change personal data or submit applications
when applying for financial or governmental services
when providing information to employers or health insurance companies
Where can you find your tax identification number?
If you have lost or forgotten your tax ID, you can find it in several places, for example:
Tax assessment notice (Steuerbescheid):
Your tax ID is printed in the personal information section of your annual tax assessment.
Annual wage tax statement (Lohnsteuerbescheinigung):
Issued by your employer, this document also contains your tax ID.
Letters from the tax authorities:
When the tax ID is first issued, it is sent by post in a letter from the Federal Central Tax Office.
If you still cannot find your tax ID, you can fill out an online form on the website of the Bundeszentralamt für Steuern and request that your number be sent to you again.
What is the difference between a tax identification number and a tax number?
Tax identification number (Steueridentifikationsnummer):
A permanent, lifelong number used to identify individuals in all tax-related matters. It does not change.
Tax number (Steuernummer):
Usually used for business and self-employment purposes, for example in tax returns filed by self-employed persons. This number can change, for instance when you move to a different tax office district.
Conclusion
The tax identification number is a key element of the German tax system and is required for all tax-related procedures. It is important to keep it safe and to provide it whenever needed – for example when dealing with the tax office, your employer, or public authorities in connection with tax issues.
