Irish Auditing and Accounting Supervisory Authority

The Irish Auditing and Accounting Supervisory Authority (IAASA) is the independent regulator tasked with safeguarding the quality of corporate reporting and ensuring an accountable auditing profession across Ireland. By setting and maintaining ethical, auditing and assurance standards, IAASA provides the framework that auditors and accounting firms rely on to deliver trustworthy financial statements.

Its core services include publishing up‑to‑date auditing standards and guidance, managing auditor notifications such as resignations, and overseeing the registration of third‑country auditors. IAASA also offers a wealth of resources – from news updates and specialist publications to consultation papers on revisions to International Standards on Auditing (Ireland) and the Corporate Sustainability Reporting Directive (CSRD). Through its Technical Advisory Panel and regular public consultations, the Authority engages directly with stakeholders to shape future regulatory practice.

With a clear focus on transparency and professional excellence, IAASA serves auditors, accounting professionals, listed companies and the wider public, helping to maintain confidence in Ireland’s financial markets.
