What is Tax ID and Tax number in Germany? [2026] - Live In Germany

Germany issues every registered resident two separate tax numbers, and they are not the same thing. The Steuerliche Identifikationsnummer (tax identification number, or Steuer-ID) is an 11-digit lifetime number assigned to you by the Bundeszentralamt für Steuern (Federal Central Tax Office). The Steuernummer (tax number) is a different, shorter number assigned by your local Finanzamt (tax office) for filing returns. When I moved to Wolfsburg in 2023 and had to sort out my tax documents with a new Finanzamt, the confusion between these two nearly cost me a delayed payroll setup. They look similar but serve completely different purposes.

According to Destatis, Germany had over 84 million registered residents in 2026, and every single one holds a Steuer-ID. That number never changes, even if you move cities or switch jobs. Your Steuernummer, on the other hand, changes every time you relocate to a new tax district.

This article covers what each number is, how to get them, what a german tax id example looks like, and what freelancers need to know about the fiscal number and VAT ID in Germany. If you have ever Googled “german tax identification number” and ended up more confused than before, this is the guide you needed.

What is a Tax ID? (Steuer-ID)

What is a Tax ID in Germany? The Steuer-ID is a permanent 11-digit number issued automatically to every registered resident by the Bundeszentralamt für Steuern (Federal Central Tax Office), and it never changes for your entire lifetime.

The Steueridentifikationsnummer (tax identification number), or Steuer-ID for short, is an 11-digit permanent number assigned to every person registered as a resident in Germany, regardless of nationality. Germany introduced it in 2007 to centralize income tax administration, replacing the older regional systems. Numbers issued before 2007 are still technically valid but are being phased out gradually.

Once you complete your

You’ll see this number requested under several names on official forms. It appears as Steuerliche Identifikationsnummer, Steuer-IdNr., IdNr, or simply Identifikationsnummer. They all mean the same thing.

Your employer needs this number to calculate your income tax correctly. Without it, German tax law requires employers to apply the least favorable tax bracket, which means a noticeably higher deduction from your Nettolohn (take-home pay, i.e. your salary after taxes and social contributions). You can recover the excess through your annual tax return, but it’s cleaner to sort it out upfront. According to the Bundeszentralamt für Steuern, over 83 million Steuer-IDs had been issued in Germany as of 2026.

How Can You Get a Tax ID?

How do you get a German Tax ID? Your Steueridentifikationsnummer (tax identification number) is issued automatically once you complete your Anmeldung (address registration) at the local Bürgeramt (citizens’ registration office) — there is no separate application.

Germany requires all residents staying longer than three months to complete the Anmeldung within 14 days of moving in.

For the Anmeldung itself, you need two things: a valid passport or national ID card, and a completed Wohnungsgeberbestätigung (landlord confirmation of residence, the form your landlord is legally required to provide). Once the registration is processed, you receive an Anmeldebescheinigung (registration certificate) on the spot.

The tax ID itself does not come from the Bürgeramt. The Bundeszentralamt für Steuern (Federal Central Tax Office) automatically generates and mails it to your registered address. That letter typically arrives within two to four weeks. You cannot walk in and collect it in person. If it never arrives, you can request it directly from the Bundeszentralamt für Steuern using their official online form.

Where To Find Your Tax ID?

Your German tax identification number (Steueridentifikationsnummer) appears on several official documents, so losing track of it is rarely a crisis.

The most reliable source is the letter sent by the Bundeszentralamt für Steuern (Federal Central Tax Office) after your Anmeldung (address registration). This letter arrives at your registered address within a few weeks and contains your 11-digit Steuer-ID printed clearly. File it somewhere safe. You will need this number for every piece of correspondence with the German tax authorities.

If that letter has disappeared, your german tax id also appears on your Einkommensteuerbescheid (income tax assessment notice, the annual document your Finanzamt sends after processing your return) issued by your local Finanzamt (tax office). Check the top section of the document.

Your monthly Gehaltsabrechnung (payslip) is another quick option. Employers are legally required to print the Steuer-ID on payslips, so any recent payslip will show it. For a full breakdown of what those payslip fields mean, the guide below is worth a read.

When none of these documents are available, your Steuerberater (tax advisor) or employer’s HR department can confirm the number immediately, since both parties need it for their own records.

What Happens If I Lost My Tax ID?

How do you recover a lost German Tax ID? You can request a free replacement letter from the Bundeszentralamt für Steuern (Federal Central Tax Office) online, and it will be posted to your registered address at no cost.

The process is straightforward: fill out the official online form on the BZSt website and they’ll post your german tax identification number to your registered address.

The catch is time. The letter typically takes up to six weeks to arrive, which isn’t ideal if your employer is waiting on your german tax id before processing your first paycheck.

If you’re in a hurry, head directly to your local Finanzamt (tax office) in person. If your number is already in the system, they can print it for you on the spot. To find which Finanzamt covers your address, enter your postal code into the BZSt office finder. Worth knowing: your german identification number never changes throughout your life, so once you have it again, keep a digital copy somewhere you won’t lose it.

What is a Tax Number? (Steuernummer)

What is a Steuernummer in Germany? The Steuernummer (tax number) is a locally assigned identifier issued by your Finanzamt (local tax office) for filing tax returns, and unlike the permanent Steuer-ID, it changes every time you move to a new tax district.

The format varies by federal state. In most states it looks something like 122/1523/5965, typically running 10 to 11 digits. In the standardised federal format used for cross-state communication, it becomes a 13-digit number like 5133081508159. This unified format is what you’ll usually see when dealing with federal-level filings.

If you’ve never filed a tax return, you may not have a Steuernummer yet. That’s normal. Employees often go years without one because their employer handles withholding automatically through the Steuer-ID. Self-employed people and freelancers, on the other hand, need a Steuernummer from day one since it must appear on every invoice they issue.

A few life events also trigger changes. Moving cities means a new Finanzamt assigns you a new number. Getting married means you’ll file jointly and receive a shared Steuernummer for that household.

For employees filing their annual Steuererklärung (income tax return) good online platforms make the process straightforward. Freelancers dealing with more complex situations should consider a dedicated tool like GetSorted.

Where To Find Your German Tax Number?

Your German tax number (Steuernummer) appears on your Steuerbescheid (tax assessment notice, the document your Finanzamt sends after processing your annual return) after you file your first tax return. That document comes by post from your local Finanzamt (tax office) and is the most reliable place to find it.

Beyond the Steuerbescheid, there are a few other places worth checking. If you are employed, your employer’s payroll department keeps your tax number on file and can share it with you directly. It also appears on your annual Lohnsteuerbescheinigung (wage tax certificate), which your employer issues at the start of each year for the previous tax year.

Freelancers receive their Steuernummer by post from the Finanzamt shortly after submitting the Fragebogen zur steuerlichen Erfassung (questionnaire for tax registration). If you have misplaced it, calling your local Finanzamt directly with your personal details is the fastest way to retrieve it. According to the German Federal Central Tax Office (Bundeszentralamt für Steuern), your Steueridentifikationsnummer (tax ID) is the permanent 11-digit number that never changes, whereas the Steuernummer can change if you move to a different Bundesland (federal state) or switch tax offices.

How Can You Get a Tax Number?

How do you get a Steuernummer in Germany? When you register your business or freelance activity with your local Finanzamt (tax office), the office assigns you a Steuernummer automatically. This typically happens within four to six weeks, and no separate application is needed beyond the initial registration form.

If six weeks pass and nothing shows up, just contact your Finanzamt directly, either by phone or in person. They can confirm whether it’s been issued and resend it if needed.

One thing worth knowing: the Steuernummer is not permanent. Unlike the Steueridentifikationsnummer (your German tax identification number, issued once for life), the Steuernummer changes when your circumstances do. A change of city, a change in marital status, or relocating your business to a different Finanzamt jurisdiction will all trigger a new number. This is normal and expected. The old number simply becomes invalid for new filings, and your Finanzamt notifies you of the replacement.

So if you’ve recently moved between cities, don’t be surprised if your german tax number looks different on your next correspondence from the tax office.

Tax ID vs Tax Number

These two numbers serve different purposes, and conflating them is one of the most common mistakes newcomers make.

The Steueridentifikationsnummer (Tax ID) is permanent. It follows you for life, regardless of where in Germany you live or what you do professionally. Everyone who registers their address in Germany receives one automatically. The Steuernummer (tax number), by contrast, is tied to your local Finanzamt (tax office) and changes whenever you move to a different tax district. Freelancers need it for issuing invoices and filing tax returns.

Germany’s long-term plan is to phase out the Steuernummer entirely, with the Tax ID eventually replacing it for all purposes. For now, though, if you’re self-employed, you still need both. You apply for the Steuernummer by submitting the Fragebogen zur steuerlichen Erfassung (questionnaire for tax registration) to your local Finanzamt.

What Is The VAT Number In Germany?

What is the VAT number in Germany? The VAT number is called the Umsatzsteuer-Identifikationsnummer (value-added tax identification number), shortened to USt-ID, and it always follows the format DEXXXXXXXXX — the country code “DE” followed by nine digits.

You may have spotted this abbreviation on supermarket receipts without realising what it was. This number matters primarily if your business operates across EU borders. If you run a Kleingewerbe (small business operating below the VAT threshold) or sell exclusively within Germany, you generally do not need one. For everyone else doing B2B transactions with EU partners, the USt-ID is mandatory on every invoice and in the Impressum (legal imprint, the mandatory disclosure page) of your website.

To get a VAT number, you apply through the Fragebogen zur steuerlichen Erfassung (questionnaire for tax registration), which you submit when registering your business with the Finanzamt (local tax office). Tick the relevant boxes indicating EU business activity and the Finanzamt will issue the number separately from your standard German tax number.

One thing worth knowing: according to the Federal Central Tax Office (Bundeszentralamt für Steuern), you can verify any EU VAT number, including German ones, through their official VIES validation tool. If you have more complex questions about VAT obligations specific to your business structure, a Steuerberater (certified tax advisor) is genuinely worth consulting.

What Is The Freelance Tax Number In Germany?

What is the freelance tax number in Germany? When you register as a Freiberufler (freelancer) or self-employed business owner with the Finanzamt (German tax office), you receive a dedicated Steuernummer for your business activity that must appear on every invoice you issue to clients.

Structurally, it looks identical to the standard Steuernummer issued after your first tax assessment. The registration process starts with a seven-page questionnaire called the Fragebogen zur steuerlichen Erfassung (questionnaire for tax registration). You submit this to your local Finanzamt, either online via the ELSTER portal (Germany’s official electronic tax filing system) or in paper form. Within this form, you make two important decisions. First, whether to apply for a VAT identification number (Umsatzsteuer-Identifikationsnummer). Second, whether you qualify as a Kleinunternehmer (small business owner) under § 19 UStG, which exempts you from charging and remitting VAT as long as your annual turnover stays below €25,000 in 2026, according to the Bundesministerium der Finanzen (Federal Ministry of Finance).

The freelance tax number is separate from your personal Steuer-ID and tied to your business registration, not your residential address registration.

Conclusion

Germany’s tax system hands you multiple numbers, and mixing them up is genuinely easy. Your Steuer-ID (tax identification number) is the permanent 11-digit number issued by the Bundeszentralamt für Steuern that follows you for life. Your Steuernummer (tax assessment number) is assigned by your local Finanzamt and changes when you move cities or alter your filing status. If you work freelance or run a business, you will also deal with a separate Steuernummer for self-employment and potentially a Umsatzsteuer-ID (VAT identification number) for cross-border transactions. Each serves a distinct legal purpose and cannot substitute for the other.

Living in Wolfsburg since 2022, the one thing I would tell any newcomer is this: get your Steuer-ID sorted the moment your Anmeldung (address registration) is complete. Everything else follows from there.
