Our Role

IAASA is responsible for the supervision of the accounting profession in Ireland, comprising 40,030 members of Prescribed Accountancy Bodies (‘PABs’) in business and practice in the State.

IAASA is the competent authority for the oversight of statutory auditors in Ireland, including oversight of the manner in which the five Recognised Accountancy Bodies (‘RABs’) perform the functions assigned to them in law in respect of statutory auditors, namely approval and registration, continuing education, quality assurance systems and investigative and administrative disciplinary systems.

In addition, IAASA has direct responsibility for the inspection of audits of Public Interest Entities (‘PIEs’), comprising entities with securities listed on a regulated market, credit institutions and insurance undertakings. We directly regulate eight auditing and accounting firms in respect of this element of their work.

IAASA is responsible for examining the level of compliance of certain entities’ annual and half-yearly financial reporting with applicable financial reporting standards (in the main International Financial Reporting Standards (‘IFRS’) and Irish Generally Accepted Accounting Practice (‘GAAP’)).

IAASA is responsible for conducting investigations of issues arising from its inspection of the audits of PIEs and referrals from overseas competent authorities. IAASA also has the discretionary power to investigate non-PIE audit matters as well as whether a member of a PAB has complied with that body’s standards. IAASA may also conduct enquiries into whether a prescribed accountancy body has complied with its approved investigation and disciplinary process.

IAASA is responsible for adopting standards on auditing, professional ethics and internal quality control. Auditors are required to carry out statutory audits in accordance with these standards.

IAASA carries out a range of other activities, including registration and oversight of third country auditors, engaging with our peer European and international counterparts, and advising the Minister for Business, Enterprise & Innovation on key auditing and accounting matters.
