German Tax ID: How to Find Your Tax Number and ID in 2026

Your German Tax ID is one of the most important numbers you’ll need as a resident in Germany. If you live or work in Germany, you will need to know two crucial numbers related to taxes: the Steueridentifikationsnummer (Tax ID) and the Steuernummer (Tax Number). These numbers are essential for handling tax-related matters, including employment, freelancing, and business operations.

Understanding the difference between these numbers and knowing how to obtain them can save you time and prevent complications with German bureaucracy. This comprehensive guide will walk you through everything you need to know about your German Tax ID and Tax Number in 2026.

Understanding Your German Tax ID vs Tax Number

Many expats get confused between the German Tax ID and the Tax Number, but they serve different purposes in the German tax system. Let’s break down the key differences to help you understand which number you need for specific situations.

What is the Tax ID (Steueridentifikationsnummer)?

The German Tax ID is an 11-digit number assigned to individuals by the Federal Central Tax Office (Bundeszentralamt für Steuern – BZSt). This number remains with you for life, regardless of where you move within Germany or even if you leave the country temporarily.

You need your German Tax ID for:

• Registering with an employer for payroll purposes
• Filing annual tax returns
• Opening a bank account with providers like N26 Bank or C24 Bank
• Applying for social benefits and government support
• Setting up investment accounts and savings plans

What is the Tax Number (Steuernummer)?

The Tax Number is a 10- to 11-digit number assigned by your local tax office (Finanzamt). Unlike the German Tax ID, this number may change if you move to a different city or region within Germany.

If you are a freelancer or run a business, you will receive a separate Tax Number specifically for business use. This number must appear on all invoices and business-related tax declarations.

How to Get Your German Tax ID

Obtaining your German Tax ID is usually an automatic process, but the method depends on your specific situation. Here’s what you need to know for different scenarios.

For New Residents and Expats

If you are moving to Germany in 2026, you will receive your German Tax ID automatically by mail within two to four weeks after completing your Anmeldung Step by Step: How to Register Your Address in Germany. You do not need to apply separately or visit any office.

The process is completely automated once you register your address at the Einwohnermeldeamt (residents’ registration office). Make sure your address registration is accurate, as this is where your German Tax ID will be sent.

For Newborns in Germany

Children born in Germany automatically receive their German Tax ID by mail within a few weeks after birth. Parents don’t need to take any additional steps – the system generates the number based on birth registration data.

Keep this number safe, as your child will need it throughout their life for various financial and tax-related matters, including opening their first bank account or starting their first job.

How to Obtain Your German Tax Number

Getting a Tax Number depends on your employment status and tax obligations. The process differs significantly between employees and self-employed individuals.

For Employees

If you are employed, your employer will handle most tax-related paperwork using your German Tax ID. You typically don’t need a separate Tax Number unless you have additional income sources or plan to file complex tax returns.

However, if you want to optimize your tax situation using software like WISO Steuer or WISO Steuer, you might need additional tax numbers for specific deductions or investment income.

For Self-Employed and Freelancers

If you are self-employed or working as a freelancer, you must apply for a Tax Number at your local Finanzamt (tax office). This involves submitting a Fragebogen zur steuerlichen Erfassung (Tax Registration Form).

In 2026, this process can be completed online via ELSTER (the German tax portal), making it more convenient than ever. You’ll need to provide details about your business activities, expected income, and other relevant information.

What to Do If You Lost Your German Tax ID

Losing important documents happens to everyone, but recovering your German Tax ID is straightforward if you know the right steps to take.
