Steuernummer vs Steuer-ID

Two Different Numbers!

In Germany there are TWO tax numbers. Don't confuse them!

Steuer-ID (Identifikationsnummer)

How to get it?

• Automatically after Anmeldung
• Letter arrives by mail in 2-4 weeks
• If you didn't receive it: call Finanzamt

Where do you need it?

• Employer (when signing contract)
• Bank (when opening account)
• Familienkasse (Kindergeld)
• Krankenkasse

Don't have it / Lost it?

• bzst.de → you can request it again
• Or call: 0800 0 22 84 57 (free)

Steuernummer

When do you get it?

• At first tax filing
• Automatically issued by Finanzamt

Where do you need it?

• In tax declaration (Steuererklärung)
• As freelancer/business (invoices)

Relocation = new number!

If you change Finanzamt (different district), you'll get a new Steuernummer.

Summary:

Starting work in Germany?

1. Step 1: Anmeldung → wait for Steuer-ID letter
2. Step 2: Give Steuer-ID to employer
3. Step 3: After one year, file Steuererklärung → receive Steuernummer

Important!

• Steuer-ID is SENSITIVE DATA — don't share it with anyone
• You'll never receive Steuer-ID via email/phone (fraud!)
• Your employer can ask Finanzamt for your number
