Steuer‑ID in Germany (2026 Guide for Immigrants)
How to get your Tax Identification Number after Anmeldung
What Is the Steuer‑ID?
The Steuer‑ID (full name: Steueridentifikationsnummer, also called IdNr.) is your lifetime 11‑digit tax identification number in Germany. You receive it once, and it never changes — even if you move, change your name, or leave and return years later.
You need it for almost everything official:
Employment
Opening a bank account
Residence permit applications
Tax returns
Child benefits (Kindergeld)
Social benefits
Freelance registration
The good news: you don’t apply for it manually. It is generated automatically after your Anmeldung (address registration).
Steuer‑ID vs Other German Numbers
Number | Name | Digits | Purpose | Does it change? |
Steuer‑ID | Steueridentifikationsnummer (IdNr.) | 11 | Taxes, employment, banking, benefits | ❌ No |
Steuernummer | Tax number | 10–13 | Freelancing, tax returns | ✔ Yes (changes when you move) |
Sozialversicherungsnummer | Social security number | 12 | Pension, health insurance, sick leave | ❌ No |
Your Steuer‑ID is the main personal identifier for the tax office (Finanzamt). Employers use it to calculate and withhold taxes from your salary.
Why Immigrants Need the Steuer‑ID
Official employment (your employer cannot pay you without it)
Opening a German bank account
Applying for a residence permit
Filing a tax return (Steuererklärung)
Receiving benefits: Kindergeld, Elterngeld, Bürgergeld, Wohngeld
Freelancing (together with a Steuernummer)
How to Get Your Steuer‑ID (2026 Step‑by‑Step)
1. Complete your Anmeldung
This is the only required step. After registration, your data is automatically sent to the BZSt (Federal Tax Office).

2. Put your name on your mailbox
Do this immediately after moving in. Most lost Steuer‑ID letters happen because the mailbox has no name.
3. Wait for the letter
Normal delivery time:
2–4 weeks (standard)
6–8 weeks (summer/autumn peak)
The letter arrives in a simple envelope from BZSt addressed to your Meldeanschrift (registered address).
4. Save your Steuer‑ID
This number is for life.
Save it in multiple places:
Photo on your phone
Cloud backup
Paper copy
What to Do If Your Steuer‑ID Doesn’t Arrive
✔ Wait the full 4–6 weeks
Delays are common in large cities.
✔ Check other documents
Sometimes the number appears on:
Your Lohnsteuerbescheinigung (from employer)
Your Steuerbescheid (tax assessment)
✔ Request it again online (fastest method)
Go to the official BZSt form: bzst.de → Steuerliche Identifikationsnummer → Eingabeformular
You must enter:
Full name (exactly as in passport)
Date & place of birth
Current registered address
⚠️ For data protection reasons, the number is only sent by post, never by email.
✔ If more than 3 months passed
Send an additional written request to BZSt (Bonn).
Important: You cannot get your Steuer‑ID by:
Email
Phone
Visiting the Finanzamt (they cannot issue it)
Asking your employer
Only BZSt can send it.
