This article is for Irish company directors and founders who need to know whether their business requires a statutory audit.
If you're unsure whether you qualify for audit exemption, worried about accidentally losing it, or want to understand the size thresholds and filing mistakes that trigger mandatory audits, this guide covers the exemption rules, common ways companies lose their exempt status, and what happens if you get it wrong.
Key Takeaways
• Small companies qualify for audit exemption if they meet two of three thresholds: €12m turnover, €6m balance sheet, or 50 employees.
• Filing your annual return late strips audit exemption for the following two years, costing €4,000-€6,000 in unnecessary audits.
• Shareholders holding 10% of voting shares can force a statutory audit by serving notice one month before year-end.
• You lose exemption only after exceeding size thresholds in two consecutive years, not just one bad year.
• Claiming audit exemption incorrectly results in defective filings that must be redone with a retrospective audit at full cost.

What Triggers a Statutory Audit Requirement in Ireland?
Most small companies never need a statutory audit. But plenty of founders assume they are exempt when they are not, and plenty more lose their exemption through a procedural mistake that had nothing to do with their size.
Understanding the thresholds, the exemptions, and the ways you can accidentally lose your exempt status is one of the more useful things a director can know.
What Is a Statutory Audit?
A statutory audit is an independent examination of a company's financial statements by a registered auditor. The auditor reviews the accounts and issues a formal opinion on whether they give a true and fair view of the company's financial position.
It is not the same as having an accountant prepare your accounts. A statutory audit is a separate, independent process carried out by a qualified auditor who has no other role in preparing the figures they are reviewing.
For companies that require one, it is a significant cost, typically starting at €2,000 to €3,000 for a small company and rising steeply with complexity.
Do All Irish Companies Need a Statutory Audit?
No. Most private limited companies qualify for audit exemption under the Companies Act 2014.
The exemption exists because a full statutory audit is disproportionate for very small companies. The cost and administrative burden outweigh the benefit to shareholders who are often the same people as the directors.
Whether you qualify depends on your size, your filing history, and whether your shareholders have objected to the exemption being used.
What Are the Size Thresholds for Audit Exemption?
To qualify as a small company and claim audit exemption, a company must meet at least two of the following three conditions in the relevant financial year:
- Annual turnover of €12 million or less
- Balance sheet total of €6 million or less
- Average number of employees of 50 or fewer
These thresholds apply under the Companies Act 2014. A company that exceeds two or more of these thresholds in a given year does not automatically lose audit exemption. The test looks at the current year and the preceding year. A company that exceeds the thresholds in one year will lose the exemption for the following year if it exceeds them again.
So a single bad year does not necessarily push you into a mandatory audit. Two consecutive years above the thresholds will.
What Is a Micro Company?
Companies that are very small may qualify as micro companies under Section 280D of the Companies Act 2014. A micro company must meet at least two of the following conditions:
- Annual turnover of €900,000 or less
- Balance sheet total of €450,000 or less
- Average number of employees of 10 or fewer
Micro companies are entitled to audit exemption and also benefit from significantly reduced financial reporting requirements compared to larger small companies.
What About Dormant Companies?
A dormant company is one that has had no significant accounting transactions during the financial year. Dormant companies may qualify for audit exemption under Section 365 of the Companies Act 2014, subject to conditions including limits on balance sheet total (currently €1.27 million) and the absence of significant accounting transactions.
A dormant company that has received share capital, paid filing fees, or made a small number of transactions may still qualify as dormant if those transactions were not significant in the context of the company's activities.
If a dormant company becomes active during the year, the exemption is lost for that year and the standard size thresholds apply going forward.
When Does Audit Exemption Not Apply?
Even if a company meets the size thresholds, audit exemption is not available in every case. Companies that are excluded from audit exemption regardless of size include:
- Public limited companies
- Companies that are credit institutions or insurance undertakings
- Companies whose shares are admitted to trading on a regulated market
- Companies that are subsidiaries of groups that do not qualify for group audit exemption
For holding companies and group structures, the rules are more layered. A parent company may qualify for audit exemption only if the group as a whole meets the size thresholds on a consolidated basis.
Can Shareholders Force a Statutory Audit?
Yes. Shareholders holding at least 10% of the voting shares can serve notice on the company requiring it to obtain a statutory audit for a given financial year, regardless of whether the company would otherwise qualify for exemption.
The notice must be served no later than one month before the end of the financial year to which it relates. This right exists to protect minority shareholders who may not be directors and who want independent verification of the company's financial position. In practice it is rarely used in small owner-managed companies, but it is an important protection where investors or passive shareholders are involved.
How Do You Lose Audit Exemption?
This is where many companies get caught out. The most common way to lose audit exemption is by filing annual returns late.
A company that files its annual return late loses its audit exemption for the following two financial years. That means a company with a turnover of €500,000 and two employees can end up paying for a statutory audit simply because it missed two annual return deadlines.
The cost of those audits, typically €2,000 to €3,000 per year, vastly exceeds the late filing penalties themselves in most cases.
Other ways audit exemption can be lost include:
- The company ceasing to meet the size thresholds in two consecutive years
- A qualifying shareholder serving notice requiring an audit
- The company becoming a subsidiary of a group that does not qualify for group exemption
What Are the Consequences of Getting It Wrong?
Claiming audit exemption when you are not entitled to it means filing financial statements without an auditor's report that should have been included. That is a defective filing, and the CRO can reject it.
If the accounts are filed without an audit when one was required, the directors are in breach of their obligations under the Companies Act 2014. The company and its officers can face prosecution, and the filing may need to be redone with a proper audit report attached, incurring the cost of the audit retrospectively.
In practice, the CRO does not always catch these errors at the filing stage. But if the company is later audited by Revenue, goes through a due diligence process for investment or sale, or becomes the subject of a dispute, the defective accounts will surface and create a much bigger problem than the original audit would have cost.
What Does a Statutory Audit Actually Involve?
If your company does require a statutory audit, understanding what the process involves helps you prepare for it. The auditor will:
- Review the company's financial statements and underlying accounting records
- Test transactions and balances on a sample basis
- Confirm key balances such as bank accounts, debtors, creditors, and stock
- Review board minutes, contracts, and other documents relevant to the financial position
- Issue a written audit report to be attached to the financial statements
The process requires cooperation from the directors and management. The auditor will request supporting documentation and may ask questions about specific transactions or judgements made in preparing the accounts. The earlier you engage the auditor and the better organised your records are, the faster and cheaper the process will be.
