Relocating from the UK to Germany isn’t just about moving boxes — it’s about setting up your life admin properly. One of the first (and most important) steps is getting your German Tax Identification Number — the Steueridentifikationsnummer, or Steuer-ID.
Without it, your employer can’t run payroll, banks won’t complete account setup, and you’ll struggle with health insurance, tax returns, and even applying for benefits like Kindergeld (child benefit).
This complete 2025 guide explains what the Steuer-ID is, how you get it, what to do if it doesn’t arrive, how it differs from other tax numbers, and why it’s essential for expats.

Expat Essentials in Germany for UK Expats (2025 Complete Guide)
1) What is the Steuer-ID?
The Steuer-ID is a lifetime, 11-digit tax identification number issued to every resident of Germany by the Federal Central Tax Office (Bundeszentralamt für Steuern, BZSt).
You get it automatically after completing your Anmeldung (residence registration).
Why it matters:
- ✅ Employment – HR needs your Steuer-ID for payroll and to assign your ELStAM (electronic wage tax features).
- ✅ Banking – Most banks require it soon after opening an account (How to Open a German Bank Account in 2025).
- ✅ Health insurance – Providers use it to link your records (German Health Insurance Guide 2025).
- ✅ Tax returns – Used across ELSTER, Germany’s tax portal.
- ✅ Benefits – Required for allowances like Kindergeld and Elterngeld.

2) Steuer-ID vs. Steuernummer vs. VAT ID (USt-IdNr.)
Expats often confuse these. Here’s the breakdown:
| Number | Who needs it | Purpose | Does it change? |
|---|---|---|---|
| Steuer-ID | Every resident | Personal ID for all tax matters | Lifetime |
| Steuernummer | Freelancers/self-employed | Local tax office number for invoices | Changes if you move districts |
| USt-IdNr. | VAT-registered businesses | Cross-border VAT transactions | Stable unless business changes |
👉 Employees need only the Steuer-ID. Freelancers will also need a Steuernummer.

3) How Do You Get a Steuer-ID?
You don’t apply. It’s generated automatically once you complete your Anmeldung.
Step-by-step:
- Register your address (Anmeldung) at your local Bürgeramt.
👉 Anmeldung Explained: Step-by-Step Guide for Expats - Bürgeramt forwards your details to the tax authority.
- BZSt issues your Steuer-ID.
- You receive it by post at your registered address in about 2–4 weeks (sometimes 6 in Berlin/Munich).
⚠️ Pro tip: Make sure your name is on the mailbox exactly as registered. Otherwise, the letter may bounce.
4) What If Your Steuer-ID Doesn’t Arrive?
If you don’t receive it within 4 weeks:
- ✅ Check if your name is on the mailbox.
- ✅ Contact BZSt to request a re-issue: Request a Steuer-ID (BZSt)
- ✅ Check payslips (sometimes HR records it once payroll runs).
- ✅ Log in to ELSTER (German online tax portal) once registered: ELSTER Portal.
If you’ve lived in Germany before, you still have the same Steuer-ID — it never changes.
5) Required Documents for Anmeldung (which triggers your Tax ID)
Bring these to your Anmeldung appointment:
- Passport (UK passport valid).
- Mietvertrag (tenancy contract).
- Wohnungsgeberbestätigung (landlord confirmation).
- Anmeldung form.
- Marriage/birth certificates (for family registration).

6) Employees vs. Freelancers
Employees
- Only need the Steuer-ID.
- HR uses it for payroll (Lohnsteuer).
Freelancers/Self-employed
- Need Steuer-ID and a Steuernummer (from your Finanzamt).
- If VAT-registered, you’ll also need a USt-IdNr.

7) Families, Children & Benefits
Children also get a Steuer-ID after their first Anmeldung.
It’s required to apply for:
- Kindergeld (child benefit) via Familienkasse
- Elterngeld (parental allowance)
Keep each family member’s Steuer-ID safe — you’ll use them repeatedly.
8) Common Mistakes to Avoid
- ❌ Not registering → No Anmeldung = no Steuer-ID.
- ❌ Waiting indefinitely → If no letter in 4 weeks, request a re-issue.
- ❌ Short-term Airbnb addresses → Not accepted for Anmeldung.
- ❌ Mixing up numbers → Steuernummer is different from Steuer-ID.
- ❌ Forgetting mailbox label → Causes returned letters.
