How to Request Your First Tax Number (Steuernummer)
Navigating the Austrian bureaucracy for the first time often feels like being dropped into a labyrinth where all the signs are written in a specific brand of legalistic German that even locals find daunting. I remember sitting in my first Vienna apartment, surrounded by half-unpacked boxes, staring at a letter from the Finanzamt and wondering if I had already committed a major administrative sin. This guide solves the mystery of the Steuernummer, walking you through exactly how to request your first tax number so you can legally work, freelance, or manage your finances in Austria.
The Identity Crisis: Understanding the Steuernummer vs. Other Austrian IDs
Before you send off any forms, it is vital to understand what a Steuernummer actually is and, more importantly, what it is not. Many expats arrive in Austria and assume that the number on their e-card or their Meldezettel is their tax ID. This is a common misconception that can lead to significant delays in your registration. In Austria, your identity is split across several different numerical systems, and the tax office—the Finanzamt—operates on its own specific frequency.
The Steuernummer is a unique identification number used by the Austrian tax authorities to track your income tax obligations, VAT filings, and overall fiscal standing. It is distinct from your Social Security Number (Sozialversicherungsnummer), which is used for healthcare and pensions. While your employer needs your social security number to pay into the system, the Finanzamt needs your tax number to ensure you are being taxed at the correct rate. If you are curious about how these systems interact, you should look into Social Insurance Deductions: Where Does Your Gross Pay Go? to see the full picture of your deductions.
Another point of confusion is the difference between a standard tax number and a VAT number (UID-Nummer). The Steuernummer is your primary account number with the tax office. If you decide to start a business and your turnover exceeds certain limits, or if you are trading across EU borders, you may also need a UID-Nummer. However, you cannot get a UID without first having a Steuernummer. The Steuernummer usually consists of nine digits, often formatted as XX-XXX/XXXX. The first two digits used to represent the specific tax office where you were registered, but with the centralization of the "Finanzamt Österreich," the system has become more streamlined, even if the old formatting remains visible on many documents.
| ID Type | Issued By | Purpose | Format Example |
|---|---|---|---|
| Steuernummer | Finanzamt | Income tax, business tax, VAT filings | 12-345/6789 |
| Sozialversicherungsnummer | ÖGK / SVS / BVAEB | Health insurance, pension, social security | 1234 010180 |
| UID-Nummer | Finanzamt | Inter-EU business trading, VAT | ATU12345678 |
| Personenkennzeichen | BMI | General identity (linked to Meldezettel) | Alphanumeric string |
Identifying Your Need: When Must You Apply for a Steuernummer?
Not everyone who lives in Austria needs to proactively apply for a Steuernummer. If you are moving here for a standard office job where you are a "non-independent" employee (Unselbständig Erwerbstätig), the system often creates a tax profile for you automatically behind the scenes. When your employer registers you with the social security office, that data eventually migrates to the tax office. However, you might still want to request your number manually if you plan to file a voluntary tax return to get money back for work-related expenses or if you have specific family deductions.
The situation changes drastically if you are a freelancer or a "Neue Selbständige." In these cases, the burden of proof is entirely on you. You are legally required to notify the tax office within one month of starting your professional activity in Austria. This is a strict deadline that many expats miss because they are still busy figuring out The Meldezettel Process: Registering Your Address Legally. If you are working as a freelancer, your Steuernummer is the key to everything; without it, you cannot legally issue a formal invoice that complies with Austrian law. You can find more details on what those invoices must look like in our guide on Mandatory Elements on an Austrian Invoice (Rechnung).
There is also a "middle ground" scenario: the side hustle. Many expats come to Austria for a full-time job but decide to do some consulting or creative work on the side. In Austria, this often falls under the category of a "Geringfügige Beschäftigung" or marginal earnings if the income is very low. However, even if your earnings are small, once you cross the threshold of €730 of profit per year from self-employed work (on top of your regular salary), you must report this to the Finanzamt. This will trigger the need for a Steuernummer so you can file your annual income tax declaration (Einkommensteuererklärung). Understanding the What is the Geringfügigkeitsgrenze (Marginal Earnings) for Health Insurance? is crucial here, as your tax and social insurance obligations often trigger at different financial levels.
Navigating the Forms: A Deep Dive into the Verf24 Questionnaire
The actual process of requesting your tax number usually involves filling out a specific questionnaire called the "Fragebogen zur Betriebseröffnung." For individuals and freelancers, this is typically form Verf24. If you are setting up a more complex legal entity like a GmbH, you would use Verf25. For most expats starting out as sole traders or freelancers, Verf24 is the document that will become your best friend—or your most confusing enemy.
The form asks for very specific details that can be tricky to estimate. You will need to provide your projected turnover (Umsatz) and your projected profit (Gewinn) for the first and second years of operation. I cannot stress this enough: be realistic and perhaps slightly conservative with these numbers. If you tell the Finanzamt you expect to make €100,000 in your first year, they may immediately send you a bill for "Vorauszahlungen" (pre-payments) of income tax. This can create a massive cash flow problem before you’ve even earned your first Euro.
Another critical section of the Verf24 is the "Kleinunternehmerregelung" or Small Business Regulation. This is an elective status for those whose annual turnover remains below €35,000 (as of current 2026 regulations). Choosing this status means you do not have to charge VAT on your invoices, but you also cannot reclaim VAT on your business expenses. For many freelancers, this is a lifesaver as it significantly reduces the amount of bookkeeping required. If you choose this path, make sure to read up on Kleinunternehmerregelung: VAT Exemption for Small Businesses to ensure you meet all the criteria and understand the trade-offs.
When filling out the form, you will also be asked for your bank details. It is highly recommended to have a local or Euro-zone account ready. While some international banks work, having a local IBAN often makes the internal processes at the Finanzamt move much faster.

The Digital Route: Using ID Austria and FinanzOnline
While you can still print out the Verf24 form and mail it to the tax office, the most "modern expat" way to handle this is through FinanzOnline. This is Austria’s powerful e-government portal for all things tax-related. However, there is a catch: to use FinanzOnline effectively, you generally need an "ID Austria" (the successor to the old Mobile Signature).
If you are an expat, Activating ID Austria as a Non-Citizen Resident can be a bit of a hurdle, as it usually requires a visit to a specific government office to verify your identity. Once you have it, however, you can log in to FinanzOnline and submit your request for a tax number digitally. The system will guide you through the digital version of the questionnaire. The beauty of the digital route is that it significantly reduces the chance of your application getting lost in the mail or sitting on a desk for weeks.
Even if you don't have ID Austria yet, you can still register for a basic FinanzOnline account where your login credentials (ID, PIN, and password) are sent to you via physical mail in a secure yellow envelope. This envelope is "RSb," which means it can only be delivered to you personally or collected at the post office with ID. Once you are in the system, Logging into FinanzOnline with the ID Austria App becomes the primary way you will interact with the tax man for the rest of your life in Austria. You can use it to track your application status, file your annual returns, and even communicate directly with your assigned tax officer through a secure messaging system.
Documentation and Practical Tips for a Smooth Approval
When you submit your Verf24, whether digitally or on paper, the Finanzamt may ask for supporting documentation. They want to see that you are actually living and working in Austria. Typically, you should have digital scans or physical copies of the following ready:
- Your Passport: A clear copy of the photo page.
- Your Meldezettel: This proves your residential address in Austria.
- Your Residence Permit: If you are a non-EU citizen, they will want to see your RWR Card or other residence title.
- Professional Credentials: Sometimes, for specific regulated professions, they may ask for Certified Translations of Documents: What the Rules Demand regarding your degrees or licenses.
- A Draft Contract: If you already have a client lined up, providing a copy of the contract or a "Letter of Intent" can prove that your business activity is real and imminent.
One of the most frequent points of failure is the address. If your name is not clearly on your mailbox, the Finanzamt's correspondence will be returned as "undeliverable," and your application will be cancelled. Ensure that your name is visible on the door and the mailbox of your apartment. If you are staying in a temporary "WG" (shared flat), make sure to include "c/o [Name on Mailbox]" in your address registration.
Once submitted, the wait time for a Steuernummer can range from two weeks to two months. If you haven't heard anything after three weeks, it is perfectly acceptable to call the general Finanzamt helpline. While they are famously busy, they can usually tell you if your file has been assigned to a "Bearbeiter" (processor). Having a German-speaking friend help with this call can be a game-changer, as the technical tax language can be difficult to navigate even for those with intermediate language skills.
Post-Application: What Happens When the Number Arrives?
When your application is finally processed, you won't receive a flashy certificate. Instead, you will get a sober-looking letter—the "Veranlagungsbescheid"—which contains your nine-digit Steuernummer. Keep this document safe. This number is now your identifier for all future interactions. You will need to put it on your invoices, use it to register with the Social Security office for the self-employed (SVS), and enter it into your FinanzOnline profile.
Getting your tax number is a major milestone in your integration journey. It means the state recognizes you as an economic entity. From here, you can start exploring more advanced topics like how to Freelancing in Austria: The Neue Selbständige Legal Guide or how to manage your Social Insurance Deductions: Where Does Your Gross Pay Go?. You are no longer just a visitor; you are a contributing member of the Austrian system.
While the process is tedious, it is a one-time hurdle. Once your Steuernummer is active, it stays with you for as long as you are resident in Austria. Even if you move districts or change from a freelancer to an employee, that number remains your link to the tax office. Take the time to do it right, estimate your income carefully, and embrace the digital tools available to make the process as painless as possible.
