Of all the compliance obligations facing Irish company directors, the CRO annual return is the one that generates the most preventable cost. It is a fixed, predictable deadline. It requires documentation that any business should have in order as a matter of course. And missing it triggers a cascade of consequences that can cost a small company thousands of euros in unnecessary fees and compliance obligations.
Every year, I deal with clients who have missed their annual return date and are trying to understand what their options are. This article explains the system, the deadlines, the consequences of missing them, and what to do if you find yourself in arrears.
What Is the Annual Return?
Every Irish limited company — private limited company (Ltd), designated activity company (DAC), company limited by guarantee (CLG), public limited company (PLC) — must file an annual return with the Companies Registration Office (CRO) each year. The annual return is a Form B1.
The B1 contains the company’s registered particulars — directors, secretary, shareholders, registered address, and share capital details — as at the annual return date (ARD). It must be accompanied by financial statements (accounts) for the most recent financial year end, unless the company qualifies for and retains the audit exemption and is filing within the correct timeframe.
The B1 and its accompanying financial statements must be filed with the CRO by the date prescribed — the annual return date — each year.
How Is the Annual Return Date Determined?
For a new company, the first annual return is due six months after the date of incorporation. No financial statements need to accompany the first annual return — it is a holding return that establishes the filing cycle.
From that point forward, the company has twelve months from the date the previous annual return was made to file the next one. If your company filed its last annual return on 15 July 2025, your next return is due by 15 July 2026, and the financial statements accompanying it must be made up to a financial year end that falls at least nine months before the ARD.
This nine-month gap between the financial year end and the ARD is significant. It means that for a company with a 31 December financial year end, the annual return must be filed by no later than 30 September — nine months after year end. In practice, for most private companies, this means completing the accounts, having them reviewed or audited, and filing the B1 with the CRO all within nine months of the year end.
What Are the Consequences of Missing the Deadline?
Missing the annual return deadline — even by a single day — has two distinct consequences.
The late filing fee. The CRO charges a late filing fee of €100 for the first day late, and €3 per day thereafter, subject to a maximum of €1,200 per return. This accumulates quickly. A return filed three months late carries the maximum fee of €1,200. If you have two years of late returns, that is €2,400 in fees before you have paid a penny in accountancy costs.
The loss of audit exemption for three years. This is the consequence that catches most small company directors off guard, and it is the more financially significant one.
Under the Companies Act 2014, small private companies are exempt from the requirement to have their accounts audited, provided they meet certain size criteria and comply with their filing obligations. Once a company files its annual return late — even once, even by one day — it loses this audit exemption for the three years following the late filing.
For a company that was previously filing unaudited accounts, this means a statutory audit is now required for the next three annual return cycles — we explain exactly what that involves in our guide to what a registered auditor actually does. A statutory audit for a small Irish company typically costs between €1,500 and €4,000 per year, depending on the size and complexity of the business and the volume of transactions. Over three years, that is between €4,500 and €12,000 in additional accounting costs arising directly from a missed filing deadline.
The loss of audit exemption cannot be waived, appealed, or avoided once a late filing has occurred. The only remedy is time — completing three compliant years of on-time filing to restore the exemption.
What If You’ve Already Missed Your Deadline?
If your annual return date has passed and you haven’t filed, you are already accumulating the late filing fee. The priority is to file as quickly as possible.
The process is:
Complete your financial statements for the most recent year end. Have your accountant prepare and file the B1 on the CRO online portal. Pay the late filing fee (the fee is calculated automatically based on the number of days late). Accept that audit exemption is lost for the next three years and plan for the additional cost.
If you have missed multiple years of annual returns and the company is showing as “Strike-Off Notice Issued” or similar on the CRO register, you are in more urgent territory — as we cover in our article on the 35,000 Irish companies currently facing involuntary strike-off. Restoring a company to good standing after a strike-off notice requires all outstanding returns to be filed, all fees paid, and in some cases an application to the District Court for an order restoring the company to the register. This is significantly more expensive and time-consuming than filing on time would have been.
How to Never Miss an Annual Return Again
The simplest approach is to ensure your accountant has the annual return date on their calendar and is responsible for filing it — not just for preparing the accounts, but for actually submitting the B1 to the CRO on time.
If you manage your own CRO filings, set a calendar reminder six weeks before the annual return date. That gives enough time to gather any information needed, finalise the accounts, and complete the B1 submission without rushing.
The CRO does send reminder notices to the registered office address of the company. However, if your registered office is a previous address, a former accountant’s address, or another address that you no longer actively monitor, those reminders will not reach you. Make sure your registered office details on the CRO are current and that someone is checking correspondence sent there.
A Note on the CRO Online System
Annual returns are filed through the CRO online portal at core.cro.ie. The system allows directors, company secretaries, or authorised presenters (such as accountants and solicitors) to prepare and submit the B1 and upload the accompanying financial statements.
Payment of the filing fee (currently €20 for online filing, rising to the late fees described above if applicable) is made online at the point of submission.
If you are not familiar with the system and are approaching your annual return date, engage your accountant in good time. Last-minute submissions can be complicated by technical issues, queries about the financial statements, or requests for additional information from the CRO.
The core principle here is simple: a missed annual return is always more expensive than a filed one. The fee, the audit obligation, and the management time spent sorting out the aftermath all exceed the cost of maintaining a straightforward filing calendar.
