Irish Audit and Accounting Supervisory Authority

What Irish Audit and Accounting Supervisory Authority does

The Irish Auditing and Accounting Supervisory Authority (IAASA) is Ireland's statutory regulatory body for audit and accounting, established in 2005 under Irish company law and headquartered in Dublin. It holds exclusive supervisory authority across four functions: Professional Body Supervision (PBS) of prescribed accountancy bodies, Assurance Quality Supervision (AQS) of PIE audit firms through inspections, Corporate Reporting Supervision (CRS) of financial reporting by listed and other relevant entities, and Standards and Policy, where it adopts and adapts auditing and assurance standards for the Irish market. Its statutory powers include revocation of recognition of accountancy bodies (exercised via section 931(4) of the Companies Act) and binding standards issuance.

IAASA's core "products" are regulatory rather than commercial: International Standards on Auditing (Ireland), International Standards on Review Engagements, ISAE (Ireland) 3000, Ethical Standard for Auditors (Ireland), Standards for Investment Reporting (Ireland), and Irish Quality Management Standards (ISQM 1, ISQM 2, revised ISA 220). These are adopted under licence from the UK Financial Reporting Council with Ireland-specific adaptations, supplemented by Guidance Notes (e.g., on Irish credit unions and auditor reporting duties) and an Explainer Video Series. Supporting outputs include consultation papers, an Inspection Insight Series evaluating audit quality (e.g., Engagement Quality Reviews), a three-year Work Programme (2026-2028), and an Annual Report.

The business model is statutory levy-based rather than commercial. IAASA funds operations through levies on public-interest entity audit firms and supervision fees from regulated entities, with a 2026 consultation expanding the PIE levy to include CSRD assurance fee income. It has no commercial go-to-market — outreach is via its website (iaasa.ie), a Mailchimp newsletter, LinkedIn and YouTube channels, public consultations, and events such as the annual Audit Committee Briefing. Headcount is 11-50; funding is not derived from external investment or commercial revenue.

Revenue model

1. Statutory Levies and Supervision Fees: As Ireland's statutory supervisory authority for auditors and accountants, IAASA funds its operations through statutory levies imposed on public-interest entity firms and supervision fees from regulated entities. The 2026 consultation on amending the public-interest entity firm levy to include CSRD assurance fee income alongside statutory audit fee income indicates a levy-based funding model.

Broad incumbents

• Autoriteit Financiële Markten (AFM): The Netherlands' integrated financial regulator covering audit oversight alongside securities supervision and consumer protection. It is a broader incumbent performing the same audit supervision function as IAASA but as part of a wider regulatory portfolio.
• Public Company Accounting Oversight Board (PCAOB): The US national audit regulator performing firm inspections, standard setting, and enforcement. It is a broad incumbent peer operating at much greater scale than IAASA but with functionally analogous responsibilities for public-company audit oversight.
• Commissione Nazionale per le Società e la Borsa (CONSOB): Italy's securities and corporate reporting regulator with audit oversight functions. Comparable to IAASA on the corporate reporting supervision dimension, but operating as a broader financial markets regulator.
• Australian Securities and Investments Commission (ASIC): Australia's integrated corporate, markets, and audit regulator. Comparable to IAASA on the audit oversight and corporate reporting dimensions, though operating as a much larger multi-purpose regulator.
• Financial Services and Markets Authority (FSMA): Belgium's integrated financial regulator with audit oversight responsibilities. It is a broader incumbent operating across financial markets and audit supervision, comparable to IAASA's audit functions but with a wider remit.

Direct peers

• Financial Reporting Council (UK): The UK's statutory regulator for auditors, accountants, and actuaries. It is the most direct peer because IAASA adopts its auditing standards under licence and performs the same fundamental functions (audit firm supervision, standard setting, enforcement) for the UK market.
• Financial Reporting Council (FRC) — but also comparable national EU audit overseers such as France's H3C: France's Haut Conseil du Commissariat aux Comptes is the national audit supervisory authority performing PIE audit oversight, standard setting, and disciplinary functions. It is a direct peer as the French national equivalent of IAASA within the EU CEAOB coordination framework.
• Abschlussprüferaufsichtsstelle (APAS): Germany's federal audit oversight authority, operating under BaFin. It supervises PIE audit firms and the German profession with the same statutory mandate as IAASA, making it a direct functional peer within the European audit regulatory network.
• Instituto de Contabilidad y Auditoría de Cuentas (ICAC): Spain's national audit and accounting oversight authority, performing PIE audit supervision, standard setting, and corporate reporting review under Spanish law. It is a direct functional peer operating in the same regulatory domain within the EU.

Others

• Committee of European Auditing Oversight Bodies (CEAOB): The EU-level coordination body bringing together national audit supervisors including IAASA. It is an ecosystem participant rather than a direct competitor, but IAASA's effectiveness in cross-border audit matters depends on its standing within CEAOB.
