Tax number at the Finanzamt: Steuernummer
The list of documents needed by a newcomer to Austria looks chaotic until you master the main rule: almost everything below depends on one document—Meldezettel, proof of residence registration. If you have just arrived and haven't yet registered your address, read the section on Meldezettel first and go to the Meldeservice, then return to the rest of the documents. This is the detail newcomers most often skip—and it blocks everything else that follows.
The tax number, Steuernummer, is issued by Finanzamt—Austria's tax authority, which since 2021 operates as a single structure, Finanzamt Österreich, replacing the former regional inspectorates. Despite Steuernummer often being called the "first document," it is not immediately needed by everyone. A person who has just arrived, is not yet working, and is not conducting business simply won't need a tax number in the first weeks.
The number becomes necessary in three typical situations: when you start official employment and your employer files your information with tax authorities; when you register self-employment or a company; and when you file an annual tax return, Einkommensteuererklärung, for example to recover some of the tax paid. Applications are submitted through the FinanzOnline portal or in person at the Finanzamt at your place of residence—and here again the address question arises: without confirmed residence registration via Meldezettel, the application won't be accepted, because the number is tied to the specific district corresponding to your actual residence.
Legal advice. If you plan to start a company or register as self-employed in Austria, obtaining Steuernummer is just one step in a broader chain that includes registration with the chamber of commerce, choosing a business form, and coordinating with SVS entrepreneur insurance. We guide the entire chain from day one—details in the business in Austria section.
Social insurance number (SVNR) and e-card
Sozialversicherungsnummer (SVNR)—a ten-digit number assigned by the insurance carrier when a person is first registered in the social insurance system. For an employee, this registration is done by the employer through the ELDA system before the first day of work; for self-employed individuals or those registering for voluntary insurance (Selbstversicherung), registration happens in person at OeGK—the Austrian health fund, which since 2020 has unified the former regional funds into one national structure.
Physical proof of insurance is the e-card—a plastic card that must be presented to every doctor and pharmacy for prescription medications. After registration, the e-card is not issued immediately: it is manufactured and mailed to the address listed in the registration, usually within two to four weeks. While the card is in transit, doctors accept temporary insurance confirmation—a certificate from OeGK, which you should have printed or in an app when visiting.
The same principle applies here as with the tax number: without a properly registered address, the card will either get lost or not be produced at all, because the insurance system cross-checks addresses with the residential registry. Those who haven't yet registered should arrange with OeGK in advance an alternative way to receive the card—in person at a service center rather than by mail.
Meldezettel: address registration that opens everything else
Meldezettel, or officially Anmeldung der Unterkunft, is the registration of your actual place of residence, which Austrian registration law (Meldegesetz) requires to be completed within three days of moving in. This is not a mere formality: this document—and its entry in the centralized resident registry, Zentrales Melderegister—is what everything else described in this article depends on.
Registration takes place at Meldeservice: in Vienna this is the Magistratisches Bezirksamt of your district; in other federal states it is the Gemeindeamt, Stadtamt, or town hall at your place of residence. For registration you need your passport (and, if applicable, a residence status document—Vertriebenenausweis or Aufenthaltstitel) and the signature of the Unterkunftgeber—the person providing housing—on a form confirming that you actually live there. Without this signature, registration won't be accepted, and this creates the first typical problem: landlords renting informally often refuse to sign Meldezettel, fearing tax consequences for themselves.
Legal advice. Meldezettel is not just another item on a checklist but a document on which everything else silently depends: delivery of the e-card, acceptance of the Steuernummer application, opening a bank account, submitting or extending an Aufenthaltstitel, enrolling a child in school. When planning a move or rental, clarify in advance whether the landlord is willing to sign the registration—it saves weeks later.
After registration, you receive Meldebestätigung—a paper confirmation you should have in several copies, as various institutions regularly request it simultaneously. When moving, the previous registration must be closed (Abmeldung) and a new one opened within the same three-day window. Those who are careless about re-registering with each move face gaps in their residence history—and continuity of this history is checked when applying for permanent residence or citizenship. The list of documents accompanying the application and renewal of residence permits is detailed in the migration in Austria section.
Apostille on Ukrainian documents
Ukraine and Austria are both signatories to the 1961 Hague Convention on apostilles, so in the vast majority of cases, a Ukrainian public document to be presented to an Austrian authority does not require full consular legalization—an apostille certified by the competent authority in Ukraine is sufficient. The Ministry of Justice of Ukraine certifies apostilles on birth, marriage, divorce, and criminal record certificates; the Ministry of Education and Science certifies them on diplomas and academic transcripts.
Full legalization instead of apostille is needed much less often than people think: mainly when the document was issued by an authority whose competence Austria does not formally recognize under the convention, or when the original is missing and must first be recovered. If a document was issued in territory not controlled by Ukrainian authorities at the time of issue, or is lost entirely, the process does not start with an apostille but with recovering the document from the state registry authority in Ukrainian-controlled territory—we detailed this step-by-step in an article on recovering documents in Ukraine.
If you don't have the needed document at all—for example, a criminal record certificate or an extract from the civil status registry—you first order it from Ukraine and only then get it apostilled. The process of obtaining such certificates remotely, without being present in Ukraine, is described in the article on certificates and extracts from Ukraine.
The order of steps matters: apostille is placed on the original document (or on a notarized copy, depending on document type) before translation, not after. If you translate first, the apostille will still have to be translated separately, because the Austrian authority accepts the translation and apostille together as a single unit—meaning you will have to work with a translator twice.
Certified translation by a court-appointed translator
Ukrainian documents, even with an apostille, are not understandable to an Austrian authority on their own—a German translation is needed. But not every certified translation is accepted equally: as a rule, Finanzamt, MA 35, Standesamt, and other agencies recognize only translations done by a gerichtlich beeideter Dolmetscher—a court-appointed translator listed in Austria's official registry of court translators. A translation certified even by the best translator in Ukraine and notarized there usually has to be redone in Austria—one of the most expensive and painful mistakes, because money and time are wasted twice.
What makes a translation acceptable to an agency: the translator's stamp and signature with a number from the registry of certified translators, and for most documents, physical binding of the translation to the original or its certified copy with a cord and the translator's seal (durchgehend geheftet), so the translation and the document it was made from are presented as a single inseparable package. A translation submitted separately without the attached original usually won't be accepted by the agency.
Translation cost is usually calculated per standardized line or page, and the time frame depends on the document type and the translator's workload—there are relatively few Ukrainian translators in Austria, so for complex documents you should allow not a few days but one to two weeks.
Diploma recognition: Nostrifikation and ENIC NARIC
A Ukrainian diploma or secondary school certificate has no legal force in Austria on its own—it must either be fully recognized or you must obtain an official assessment of its equivalence level. These are two different procedures in terms of cost, duration, and outcome, and the most expensive mistake here is choosing the harder one when the easier was actually needed.
Nostrifikation—full recognition of a higher education diploma, which equates it to a specific Austrian degree. It is needed for regulated professions—medicine, law, teaching in a state school—as well as for admission to graduate programs or work in the civil service where the position directly requires an Austrian or fully recognized diploma. An analogous procedure for a full secondary school certificate is called Nostrifikation and is mainly needed for admission to an Austrian university on general terms.
For most other situations—a private employer wants to understand your education level, or a document is needed simply as proof of qualification—it is sufficient to request an official assessment of comparability from ENIC-NARIC Austria (Zeugnisbewertung). This is faster and substantially cheaper than full Nostrifikation, and for the vast majority of employment outside regulated professions, this assessment is entirely adequate.
Legal advice. Before submitting a diploma for Nostrifikation—a procedure that takes months and costs substantially more than an ENIC-NARIC certificate—find out from your prospective employer or educational institution which exact form of recognition they actually need. We regularly see clients who have already paid for full recognition when the employer needed only a simple comparative assessment.
Both procedures require an apostilled diploma with a certified translator's translation and, as a rule, an academic transcript listing subjects and hours—so the sequence apostille-then-translation saves not only time but also money: redoing the package twice costs more than assembling it correctly the first time.
Opening a bank account
A bank account is usually the last step in this list, and also the place where confusion accumulated earlier hits your wallet hardest. The bank requires Meldezettel, proof of identity, and for a full account often also Steuernummer or proof of income—an employment contract, salary certificate, or self-employment statement. For those who don't yet have the full package, banking regulations on basic payment accounts guarantee the right to Basiskonto—a simplified account for practically anyone who is legally in the EU.
The bank's compliance department checks documents not formally but substantively: it verifies the spelling of surname and first name in Latin characters on all submitted documents, date of birth, and consistency of address with Meldezettel. Here emerges a problem rarely anticipated: a Ukrainian surname is transliterated differently in different documents—in the foreign passport under one set of rules, in an old Soviet-era birth certificate under different rules, in a diploma translation under yet others. A bank seeing three spellings of the same surname in one package either stops the account opening or demands confirmation that it is the same person.
This is where you can see why the entire chain of documents is best handled with legal support rather than piecemeal. We verify the spelling of name and surname across all documents before submission and, if there is a discrepancy, we prepare a brief identity confirmation letter that resolves the bank's questions immediately. We plan the sequence so apostille and translation proceed in parallel with Meldezettel registration where possible, not one after the other—this saves weeks compared to ordering each document only after the previous one is finished. And if any agency—Finanzamt, OeGK, MA 35, or the bank—raises an objection or requests additional documents, we prepare the response to resolve the issue with one letter rather than a series of clarifications over months. Figuring out which documents you need for your situation is easiest at a consultation, where we can immediately see which papers you have, which are missing, and in what order to obtain them.
Frequently asked questions
How much time do I have to register Meldezettel after arriving in Austria?
Registration law requires you to register your place of residence within three days of moving in. This applies both to first registration after arrival and to each subsequent move to a new address—the old registration must be closed and a new one filed within the same three-day period.
Do I need Steuernummer right after arriving in Austria?
No. The number becomes necessary only when you start official work, register as self-employed or open a company, or file a tax return.
Is apostille or full consular legalization needed for Ukrainian documents?
In the vast majority of cases, apostille is sufficient—Ukraine and Austria are both signatories to the Hague Convention. Full legalization is rarely needed: mainly when the document was issued by an authority whose competence Austria does not formally recognize under the convention, or when the original is missing and must first be recovered.
Will an Austrian authority accept a translation made in Ukraine?
Usually not. Finanzamt, MA 35, and other agencies typically recognize only translations made by a court-appointed translator registered in Austria itself. Translations from Ukraine usually have to be redone here.
Must I go through full Nostrifikation of a diploma, or is an ENIC-NARIC certificate enough?
It depends on the purpose. For regulated professions, the civil service, or admission to graduate programs, full Nostrifikation is required. For private employment outside regulated professions, an official comparative assessment from ENIC-NARIC Austria is usually sufficient—faster and cheaper.
None of these documents exists in isolation: Steuernummer is tied to an address, e-card depends on correct registration, the bank checks name consistency across papers, and diploma and apostille must be presented in the right order to avoid redoing the translation twice. The most expensive mistakes in this list aren't in any single document but at the junctures between them, where one agency waits for a result from another. Systematic support for the entire package from day one in Austria remains the most reliable way through this process without lost weeks and repeated expenses.
