Guide to Getting Your German Tax ID (Steueridentifikationsnummer)

To get a German Tax ID (Steueridentifikationsnummer), you must first register your address (Anmeldung) at your local Citizens’ Office (Bürgeramt). This is mandatory for anyone planning to work in Germany or stay longer than three months.

What Exactly is a Steueridentifikationsnummer?

The Steueridentifikationsnummer (literally, “tax identification number”) is your personal, unique tax ID in Germany. It is often abbreviated as IdNr or Steuer−ID.

Think of it like a Social Security Number in the US or a National Insurance Number in the UK, but specifically for tax purposes.

Key features of the Steuer−ID:

• Unique and Permanent: You are assigned one Steuer−ID that remains with you for your entire life. It never changes.
• 11-Digit Number: It is always a unique 11-digit number.
• Issued by the BZSt: It is issued by the German Federal Central Tax Office, the Bundeszentralamtfu¨rSteuern (BZSt).

Important: Do not confuse the Steueridentifikationsnummer with the Steuernummer.

• Steueridentifikationsnummer (IdNr): For everyone. It’s your personal, permanent identifier.
• Steuernummer: A separate number assigned by your local tax office (Finanzamt) once you start freelancing, open a business, or file your first tax return as a couple. You may have multiple Steuernummern throughout your life if you move or your work status changes, but you will only ever have one Steueridentifikationsnummer.

Why Do You Need a German Tax ID?

Your Steuer−ID is one of the most crucial pieces of information for life in Germany. You will need it for:

• Employment: Your employer must have your Steuer−ID to correctly calculate and pay your income tax and social security contributions. Without it, you’ll be placed in the highest tax bracket (Tax Class VI), meaning much more tax will be withheld from your salary until you provide the number.
• Opening a Bank Account: Most banks require your Steuer−ID to manage taxes on any interest you might earn.
• Applying for Benefits: You’ll need it to apply for government benefits like child benefits (Kindergeld).
• Filing a Tax Return: It’s the primary identifier when communicating with the tax authorities.
• University Enrollment: Some universities may ask for it during the enrollment process.

How to Get Your German Tax ID

1. Register Your Address:
   • Register your German address at the local Bürgeramt within 14 days of arrival.
   • You will receive an Address Registration Certificate (Meldebescheinigung).
2. Receive Your Tax ID:
   • After registration, the Federal Central Tax Office (Bundeszentralamt für Steuern) will automatically generate and send your Tax ID by post to your registered address.
   • This typically takes two to three weeks to arrive.
   • Crucially, ensure your name is clearly on your mailbox to receive the letter. 

If You Don’t Receive It or Need it Faster

• Visit the Local Tax Office (Finanzamt): If you haven’t received your Tax ID within three weeks or need it faster, you can visit your local Finanzamt.
  • Bring your passport and Meldebescheinigung.
  • Non-EU citizens may also need their Residence Permit (Aufenthaltstitel).
  • In some cases, the Finanzamt can provide the ID immediately or send it within a few days.
  • Some sources suggest waiting a few days after registration before visiting the Finanzamt to allow the system to update.
• Apply Online: You can submit an online request via the Bundeszentralamt für Steuern website if you have not received it. 

Where to Find Your Tax ID (If You Already Have One)

You can typically find your German Tax ID on payslips, the annual income tax statement (Lohnsteuerbescheinigung) from your employer, a tax assessment (Steuerbescheid) from the tax office, or in your online ELSTER account. 

Lost Tax ID

If you lose your Tax ID, you can request a replacement online through the Federal Central Tax Office’s website which may take up to eight weeks. Alternatively, you can visit your local Finanzamt in person with your passport or check old payslips and tax documents. 

Getting your German tax ID is a simple, passive process for most people. By completing your Anmeldung promptly, you set the wheels in motion, and this vital number will soon be in your hands, unlocking the next steps of your life in Germany.
