German residents have different tax identification numbers. This guide explains what they are, and where to find them.
The tax ID (Steuer-ID)
This is your unique, permanent tax identification number. Every German resident has a tax ID. The Finanzamt uses your tax ID to identify you. It has the format “12 345 678 901”. Your tax ID is permanent; it never changes.
The tax ID is also called…
- Steuerliche Identifikationsnummer
- Persönliche Identificationsnummer
- Identifikationsnummer
- Steuer-IdNr.
- SteuerID
- IdNr
Why you need a tax ID
You need a tax ID to…
- Get paid correctly
If you don’t have a tax ID, you can still work and get paid, but you pay more salary tax.1 You can get that money back later by filing a tax return.2 Some employers think that you can’t work without a tax ID, but they are wrong. - Open a bank account
Some banks ask for a tax ID when you open an account. - Apply for Kindergeld and Elterngeld
- Get a Kitagutschein
Your children need a tax ID to get a Kitagutschein and send them to daycare. - Start a business
You need a tax ID to register your business with the Finanzamt.
How to get your tax ID
You get a tax ID when you register your address for the first time.9 4 to 6 weeks later, you get a letter from the Bundeszentralamt für Steuern with your tax ID.
If you can’t register your address, fill this form. You will get your tax ID by post 4 to 6 weeks later. This does not always work.
If you registered your address before, you already have a tax ID. You just need to find it.
If you did not get your tax ID after 6 weeks, request it again. You can also go to your local Finanzamt with your passport, and ask for your tax ID.3 You don’t need an appointment. A lot of people never get their tax ID letter.
Where to find your tax ID
If you already have a tax ID, you can find it on…
- The letter from the Bundeszentralamt für Steuern. You get it 4 to 6 weeks after your first Anmeldung
- Your pay slip (Gehaltsabrechnung)
- Your salary tax statement (Lohnsteuerbescheinigung) as “Identifikationsnummer”
- Your income tax assessment (Steuerbescheid) as “IdNr”
- In ELSTER under Meine Profile
If you can’t find your tax ID…
- Go to your local Finanzamt with your passport, and ask for your tax ID.3 You don’t need an appointment. If they won’t help you, go to another Finanzamt.
- Fill this form, and get a letter from the Finanzamt in around 4 weeks. They will send it to the address you registered, not anywhere else. Make sure that your name is on your mailbox.
Your employer and your tax advisor also know your tax ID. Ask them.
The tax number (Steuernummer)
The Steuernummer is for freelancers and businesses. It’s a 10 or 11 digit number, and has the format “12/345/67890”. It’s sometimes written as “3012034567890” (the first two digits are the number of your Bundesland5). It’s also called Steuer-Identnummer or St-Nr.
