Steuer-ID in Germany: How to Find and Retrieve Your Tax ID
Learn how to get your Steueridentifikationsnummer, request a replacement letter, and correct registration details.
The tax identification number (Steueridentifikationsnummer or Steuer-ID) is a unique, permanent 11-digit number assigned to every individual registered in Germany. Introduced to streamline the taxation system, this number remains with you for your entire life and does not change when you move, change jobs, or marry. It is entirely different from the tax number (Steuernummer), which is issued by your local tax office for specific tax declarations.
For newcomers, the Steuer-ID is generated automatically after you complete your address registration (Anmeldung) at the Bürgeramt. The Federal Central Tax Office (Bundeszentralamt für Steuern or BZSt) sends this number to your registered address by post. It is essential to share this number with your employer immediately to ensure you are placed in the correct tax class; otherwise, you will be taxed at the highest rate (Tax Class 6) by default.
If you lose your Steuer-ID letter or never received it, there are several ways to recover it. You can check your previous payslips or annual tax statements (Ausdruck der elektronischen Lohnsteuerbescheinigung), where it is always printed. Alternatively, you can submit an online request portal on the BZSt website to have the letter resent to your home, which takes several weeks for security reasons.

💶 Costs and Timelines
Obtaining or recovering your Steueridentifikationsnummer is completely free of charge. For the year 2026, the BZSt does not charge fees for issuing or mailing the number. If you request the tax ID to be resent online, the processing time typically ranges from 4 to 6 weeks, though it may take longer during periods of high administrative volume. The letter is sent directly to your registered residential address.

❓ Frequently Asked Questions
Is the Steuer-ID the same as the Steuernummer?+
No. The Steuer-ID is a permanent lifetime number. The Steuernummer is a temporary number assigned by the local Finanzamt for tax returns or business activity.
How can I get my Steuer-ID faster?+
You can visit your local Finanzamt in person about 5-7 days after your Anmeldung. They can often print the number for you on the spot if it's already in the database.
Do children receive a Steueridentifikationsnummer?+
Yes, children born in Germany or registered here receive their own Steuer-ID shortly after birth or registration to facilitate child benefit claims.
What happens if I work without a Steuer-ID?+
Your employer is legally obligated to tax your salary under Tax Class 6 (Steuerklasse 6), which has the highest deduction rate. You get the overpaid tax back after filing a tax return.
Can I request my Steuer-ID at the Bürgeramt?+
No, the Bürgeramt only registers your address. The number is issued by the Federal Central Tax Office (BZSt), though the Finanzamt can view it.
Does my Steuer-ID change if I leave Germany?+
