What FinanzOnline is

FinanzOnline is Austria’s online portal for tax and financial administration with the tax authority. Individuals can use ID Austria to access it without a separate initial registration in FinanzOnline. The portal supports electronic employee tax assessments, annual returns, declarations, and applications, and provides procedures and information for businesses, municipalities, tax professionals, banks, and insurers. ID Austria is the standard sign-in method and meets the legal two-factor authentication requirement; alternative credentials also require two-factor authentication. Other listed electronic sign-in options include a signature card, FIDO security key, and EU Login. FinanzOnline uses TLS for encrypted access and requires cookies and JavaScript. Data-stream submissions need separate software that creates XML files matching the Ministry’s published structures; the portal does not provide that software. Those submissions receive an immediate formal check and a later content check, with results shown in the submission log. The Ministry recommends packages below 5 MB and no more than 50 declarations. Access is free, with web, Android, iOS, and API platforms listed.
