Austria introduces new FinanzOnline login rules and penalties

Starting January 1, 2027, new regulations for the Austrian FinanzOnline portal will phase out traditional login credentials for private individuals. The ID Austria will become the primary standard for access. While users may also use high-security electronic identities from other EU member states or traditional credentials paired with two-factor authentication, the use of fax for written applications will be discontinued.

Strict new rules regarding data entry will also take effect. Users must utilize specific functions for approximately 130 different types of requests. The general “Sonstige Anbringen und Anfragen” (Other submissions and inquiries) function may only be used in exceptional cases where no specific form exists. Repeatedly using incorrect transmission methods despite official written requests from the tax office could result in fines of up to 700 euros.
