Tax ID Germany after Anmeldung: Steuer-ID Letter, ELSTER (2026)

The tax ID Germany after Anmeldung is a letter, not an extra Bürgeramt queue. The Steueridentifikationsnummer (IdNr) is issued automatically by the Bundeszentralamt für Steuern (BZSt) and posted to your Meldeanschrift.

HR will ask for it on a Werkstudent contract. The payslip article explains Lohnsteuer lines. This article covers how you get the number, where it is used, and when filing is actually required.

TL;DR

Steueridentifikationsnummer nach Anmeldung

Steueridentifikationsnummer nach Anmeldung arrives by post. You do not apply at the Finanzamt for the first issue.

• It is lifelong and stays valid if you leave Germany and return.
• BZSt will not read it out by phone or email.
• Keep a photo of the letter in a private folder, same as the Meldebescheinigung.

If weeks pass with no letter, check that Anmeldung used a mailbox you can open, then use the official resend form rather than a Facebook group.

BZSt IdNr erneut mitteilen: Steueridentifikationsnummer wo finde ich die

BZSt IdNr erneut mitteilen is how you answer Steueridentifikationsnummer wo finde ich die after a lost Steuer-ID (Steuer-ID verloren):

1. Open the form from bzst.de or the ELSTER portal (elster.de/bportal).
2. Identify yourself. The IdNr is posted again to the registered address.
3. If you already received a Lohnsteuerbescheinigung, the IdNr is printed there too.

Confirm live wording on those official pages; third-party blogs go stale.

Lohnsteuerbescheinigung and Steuerklasse 1 Werkstudent

Steuerklasse 1 Werkstudent is the usual class for a single main job. The employer pulls tax deduction data (ELStAM) using your IdNr.

Read the actual codes on the December Lohnsteuerbescheinigung. The payslip guide maps those lines. Do not copy a Grundfreibetrag figure from social media; use the amount ELSTER shows for the year you file.

Steuererklärung Studenten: when a Werkstudent must file

Steuererklärung Studenten (including Steuererklärung Werkstudent and tax return Germany students) is narrower than "everyone with a job files". Under § 46 EStG and related rules, Pflichtveranlagung commonly includes:

• A second employment taxed in Steuerklasse VI
• Certain replacement income (Lohnersatz) above the small threshold the law sets (confirm the live euro amount)
• An ELStAM Freibetrag you applied for
• A letter from the Finanzamt telling you to file

Most students with one Steuerklasse I job are not forced to file. Filing voluntarily can still return withheld Lohnsteuer if your yearly income sits in a refund zone. That is a calculation, not a slogan. This article does not tell you that you must file.

Deadlines move. Check the year on ELSTER and with your Finanzamt before you assume a date from an older guide.

ELSTER Steuererklärung students

ELSTER Steuererklärung students file (when they file) through the official portal:

1. Create an ELSTER account on elster.de.
2. Wait for the activation letter at your Meldeanschrift.
3. Import the electronic Lohnsteuerbescheinigung your employer sent, or enter it from the paper copy.
4. Submit. Keep the PDF receipt.

Commercial tax apps that "talk to ELSTER" are optional. You do not need a Steuerberater for a simple student return; you do need correct IdNr, employer tax number, and the year's forms.

Embassy and Finanzamt staff can refuse to interpret your foreign scholarship. If a diplomat or officer tells you to confirm in person, that discretion is real. Bring the IdNr letter, enrolment, and the Lohnsteuerbescheinigung.

Common mistakes

• Treating the IdNr as optional for a Werkstudent contract
• Emailing the number to a fake Finanzamt domain
• Assuming every student must file
• Missing the ELSTER activation letter because the mailbox is full
• Mixing this topic up with Rundfunkbeitrag (different letter, different office)
