The Commission Internal Audit Service (IAS) is part of the internal audit system for the European Commission and EU agencies. It provides independent, objective assurance and consulting services designed to add value and improve the operations of the Commission.
Every year there is an independent external audit of the EU’s annual accounts and resource management by the European Court of Auditors, resulting in a report for the Parliament and Council.
On the basis of this audit, the Court of Auditors issues an opinion – a 'statement of assurance' – on the figures presented and the system and controls in place. The statement marks the beginning of the annual budget discharge procedure.
