Where to find my Tax ID

Your Tax Identification Number (TIN) is unique to you, and issued by the tax authority upon registration with them in the country where you as an individual are a taxpayer.

If you’re a resident in Austria, you can request your 9‑digit Tax ID (“Steuernummer”) at your local tax authority (“Finanzamt”). You can also request it via FinanzOnline. If you’re already subject to taxation or have filed a tax return in the past, you can find your Tax ID in the following places:

• Via FinanzOnline (new tab): log in with your credentials or with your ID Austria/mobile phone signature and select on “Abfragen” → “Steuerkonto”.
• On your income tax assessment (“Einkommenssteuerbescheid”).
• At your local tax authority (new tab) (“Finanzamt”).

If you’re a resident in Germany and have registered with your local tax authority, you’ll be provided with an 11‑digit Tax ID or Steueridentifikationsnummer. Don’t confuse this with your 9‑digit Tax Number or Steuernummer.

Tax IDs aren't printed on official identity documents, but you can find your Tax ID in the following places:

• The letter you received from the Federal Central Tax Office issuing your Tax ID or IdNr (Mitteilungsschreiben über die Zuordnung einer Identifikationsnummer).
• Income tax assessment.
• Wage tax statement.

You can find more information about your Tax ID, or how to request one, here (new tab).

If you’re a resident in France and are required to file a tax return there, the French tax authorities will issue you with a 13‑digit Tax ID or Simplification des Procédures d’Imposition (SPI) once you’ve been registered in the tax authorities’ database. These numbers begin with 0, 1, 2, or 3.

You can find your Tax ID in the following places:

• On your pre‑printed income tax declaration form.
• On your tax notices and property tax notices.

If you don't have a Tax ID, you should submit a request at any office of the Italian Revenue Agency.

Tax IDs aren't printed on official identification documents, but you can find your Tax ID in the following places:

The Spanish Tax Identification Number (NIF) is an identifier required to carry out procedures with the tax authorities. The Spanish NIF consists of nine characters (the last of which is a control letter).

The NIF is the tax identifier used by the Spanish Tax Agency (Agencia Tributaria) to link all tax information to the same person. That’s why, in order to open an account and provide our services to you safely and in line with regulations, we need you to provide your NIF.

• DNI (Spanish citizens): For individuals with Spanish nationality, the Tax Identification Number is the number on the national identity document (Documento Nacional de Identidad, DNI) followed by the corresponding verification character, which is an uppercase letter. This appears on the DNI itself, in line with its regulatory provisions.
• NIE (foreign nationals with NIE): For individuals who don't have Spanish nationality, the Tax Identification Number is the Foreigner’s Identity Number (Número de Identidad de Extranjero, NIE) assigned or issued under Organic Law 4/2000 of January 11 on the rights and freedoms of foreign nationals in Spain and their social integration, and its implementing regulations.
• NIF (foreign nationals without NIE): Individuals who don't have Spanish nationality and don't have a Foreigner’s Identity Number‌ — ‌either temporarily because they are required to obtain one, or permanently because they aren't required to have one‌ — ‌must request the assignment of a Tax Identification Number from the tax authorities when they carry out transactions of a tax nature or with tax implications. This number consists of nine characters, composed as follows: an initial letter “M” indicating the nature of this number, seven alphanumeric characters, and a final alphabetical verification character.

If they don't apply for it, the tax authorities may, on their own initiative, register them in the Census of Taxpayers (Censo de Obligados Tributarios) and assign the corresponding Tax Identification Number.

You can find your Tax ID in the following documents, depending on your situation:

• National identity card (DNI)
• Electronic identity card (DNI electrónico)
• Foreigner’s identity card (Tarjeta de Identidad de Extranjero)
• New driving license (issued since 2004)
• Tax identification card (Tarjeta de Identificación Fiscal)
• Social Security card

If you live in Spain and don't yet have a Spanish Tax Identification Number, follow these steps:

For individuals with Spanish nationality (DNI)

The Tax ID is assigned when you obtain your national identity document (DNI). If you don't have a DNI, visit your nearest office of the Spanish Tax Agency (Agencia Tributaria) or a police station to apply.
