It is issued by the Finanzamt (tax office) and is separate from the social security number. This guide explains who needs a Steuernummer, how to apply at your local Finanzamt or online via FinanzOnline, what documents are required, and how long processing takes. The Steuernummer is mandatory for filing tax returns, freelance work, and self-employment in Austria.
