Accountability reports
Political parties have to compile financial statements (so-called accountability reports) on their finances on an annual basis. Since 2023, only political parties that are represented in the National Council, a provincial parliament or the European Parliament are subject to accountability. These reports must be audited and signed by an accountant. The political parties are required to submit their accountability reports for the respective previous year to the Austrian Court of Audit each year by 30 September.
Please find the political parties' accountability reports, broken down by year, here (in German).
