Every company registered under the Companies Act 2014 in Ireland is required to file beneficial ownership data with the RBO, the Central Register of Beneficial Ownership. The obligation flows from the EU 4th Anti-Money Laundering Directive and applies to new and existing companies alike, with a five-month window after incorporation to make the first filing. Despite the deadline being clear and the online process being free, the RBO is one of the more commonly missed compliance steps for new Irish companies, and the penalties for missing or inaccurate filings have become more substantial in recent years.
This article explains what the RBO is, who counts as a beneficial owner, what the 25% threshold means in practice, what to submit, how the filing actually works on the RBO portal, and the common mistakes that delay or invalidate filings.
What does “registering a beneficial owner with the RBO” actually mean?
The RBO is the Central Register of Beneficial Ownership of Companies and Industrial and Provident Societies in Ireland. It is administered by the Department of Enterprise, Trade and Employment and the Companies Registration Office under the European Union (Anti-Money Laundering: Beneficial Ownership of Corporate Entities) Regulations 2019.
The register is designed to identify the natural persons who ultimately own or control a company, regardless of how many intermediate corporate layers sit between them and the operating entity. The two obligations in practice are:
- The company must file data with the RBO, including each individual’s beneficial ownership details, within five months of incorporation, and must keep that filing up to date as the ownership structure changes. When the company has been required to register with the RBO and has done so, the beneficial ownership information is entered on the RBO register and remains live until amended
- Beneficial owners themselves must provide accurate beneficial ownership information when the company asks them, so the company can identify their beneficial owners and file correctly
The filing is made online at rbo.gov.ie. There is no fee. The data is held on a secure portal on the RBO website and is accessible to designated authorities (Revenue, the Garda, the CRO, financial institutions, and certain regulated professionals) for AML purposes.
Who counts as a beneficial owner under the RBO rules?
A beneficial owner is any natural person who ultimately owns or controls more than 25% of the company through direct or indirect ownership. The threshold for voting rights or ownership interest can be met in three different ways:
- More than 25% of the shares (direct ownership of share capital)
- More than 25% of the voting rights (which can differ from share ownership where multiple share classes exist)
- More than 25% by other ownership interest in the entity or through any other means of control (for example, the right to appoint or remove directors)
A company can have multiple beneficial owners, and frequently does. A startup with two co-founders each owning 50% has two beneficial owners. A company with four founders each on 25% has either none (if the test is “more than 25%”) or four (if local interpretation rounds to “at least 25%”); current Irish practice treats anyone holding exactly 25% as not meeting the threshold, but the rule of thumb in any borderline case is to file and document rather than omit.
Direct vs indirect ownership: what to look for
Direct ownership is straightforward: the natural person holds the shares in their own name. Indirect ownership is where shares are held through one or more corporate vehicles. The RBO requires you to look through corporate ownership chains to identify the natural person behind them. Indirect ownership of a sufficient percentage (more than 25% when you trace the chain back to the natural person) still counts as beneficial ownership.
A worked example. Founders A and B each own 50% of Holdco Ltd. Holdco Ltd in turn owns 80% of OpCo Ltd, the trading company. For OpCo Ltd’s RBO filing, both A and B are beneficial owners through indirect ownership (each owns 40% of OpCo through their Holdco shareholding). The remaining 20% of OpCo, held by another shareholder, may or may not trigger a beneficial owner entry depending on whether that shareholder’s holding exceeds 25%.
What if no one meets the 25% threshold?
If no single individual owns or controls more than 25%, the RBO requires the company to file details of the “senior managing official”, typically the CEO or equivalent. This fallback exists so that the register is never blank for a company that genuinely has no concentrated beneficial owner. The senior managing official’s personal details are entered with a role description rather than a percentage ownership.
This scenario is more common than you might think. A startup with five co-founders each on 20% has no beneficial owners under the 25% test, and the CEO (or equivalent) goes on the register as senior managing official.
What information do you need to submit for each beneficial owner?
For each individual identified as a beneficial owner or senior managing official, the company files:
- Full legal name as it appears on official identification
- Date of birth
- Nationality
- Residential address
- Personal Public Service (PPS) number for Irish residents, or a Verification of Identity number from the RBO portal for non-Irish residents
- The nature and extent of the ownership or control (specific percentage, the basis of control, or the senior managing official role)
- The date on which the person became a beneficial owner, and if applicable the date they ceased
Accuracy matters. The name on the RBO filing must exactly match the name on the person’s identification documents. Even small mismatches (a missing middle name, a different transliteration) can cause the filing to be rejected or flagged for verification.
How does the RBO filing actually work?
The end-to-end process from the company’s perspective:
- Identify all beneficial owners. Work through the cap table, look through any holding entities, and identify every natural person who meets the 25% test
- Gather the required data from each. Send a written request to each beneficial owner asking for their name, date of birth, nationality, address, and PPS number or VIN. Allow at least 14 days for them to respond
- Each beneficial owner verifies their identity. Irish-resident beneficial owners use their PPS number, which the RBO portal verifies against the Department of Social Protection’s records. Non-Irish residents apply for a Verification of Identity Number (VIN) through the RBO portal, which requires a notarised identity document
- Maintain the internal beneficial ownership register. The company must keep its own internal register of beneficial owners alongside the RBO filing, and update it as circumstances change
- File the beneficial ownership data through the RBO portal. The portal on the RBO website is the only acceptable channel; there is no paper alternative. Once the data has been filed with the RBO, the company receives a confirmation that the beneficial ownership information has been entered on the register
- Update the filing within 14 days of any change. Changes include a new beneficial owner, a beneficial owner ceasing to qualify, or a change in any of the personal details previously filed
What are the deadlines for filing with the RBO?
| Trigger | Deadline |
| New company incorporation | 5 months from the date of incorporation |
| Change in beneficial ownership (new owner, removed owner, changed details) | 14 days from when the change takes effect |
| Existing companies (pre-2019) | Already required to have an active filing; update within 14 days of any change |
Missing the five-month deadline is technically a Category 4 offence under the regulations, with fines on summary conviction. In practice, late filings are now more commonly addressed by a “voluntary strike-off” risk if filings remain outstanding, or by knock-on effects when the company tries to open a bank account, take on new investors, or undergo due diligence.
What happens if you do not file with the RBO?
Three categories of consequence:
- Legal penalties. Failure to file is an offence under the 2019 Regulations. Penalties on summary conviction can include fines of up to €5,000, and on indictment up to €500,000 plus director-level personal liability
- Banking and compliance friction. Banks, accountants, solicitors, and investors all routinely check the RBO filing as part of AML due diligence. A missing or out-of-date filing triggers immediate compliance questions and can stall account openings, lending applications, or funding rounds
- CRO downstream effects. Persistent non-compliance can affect the standing of the company at the CRO, with potential implications for the annual return and ultimately the strike-off process
None of this is theoretical. We regularly see new clients arrive at Kinore with an unfiled RBO and a bank account application stuck in limbo because of it. The fix is straightforward once you have the data and the verification numbers in place, but it can add two to four weeks of delay to whatever the business is trying to do.
How does the RBO interact with the CRO?
The RBO is administered by the same office as the CRO but is a separate register. The CRO holds details of the company itself: directors, registered office, share capital, annual returns, and accounts. The RBO holds details of the natural persons behind the corporate structure. The two are linked: the CRO’s records on directors are used as a starting point when identifying RBO filings, and the RBO data is referenced in some CRO compliance checks.
For a small private Irish company, both the CRO annual return and the RBO maintenance are typically handled by the same accountant or company secretary. Coordinating the two means a change in shareholders triggers both a CRO filing (where required) and an RBO update within 14 days.
Common RBO mistakes to avoid
The patterns we see at Kinore when reviewing existing client compliance:
- Filing only the directors and assuming that covers the requirement. Directors are not automatically beneficial owners; the test is ownership and control of 25% or more, not directorship
- Missing the indirect ownership chain. Filing only the immediate shareholder (a holding company) without identifying the natural persons behind it
- Failing to update when shareholders change. A new shareholder above 25% triggers a 14-day clock to update the filing
- Using inconsistent name formats. The legal name on the filing must match the person’s official identification exactly
- Not maintaining the internal register. The company is required to keep its own internal record of beneficial owners alongside the RBO filing
- Treating “no one over 25%” as no filing required. The senior managing official fallback applies and still requires a filing
Each of these is recoverable, but each adds time and cost when discovered during a bank check, an audit, or a due diligence exercise.
Getting your RBO filing right
If you have just incorporated a company in Ireland, the RBO filing should be on the same checklist as registering for corporation tax, opening a bank account, and setting up the CRO online services. Five months feels like a long time, but the most common reason for missing the deadline is that one beneficial owner is slow to provide their PPS number or to verify their identity, and that delay can swallow three or four weeks of the five-month window if it is not chased early.
If you are unsure whether your company’s RBO filing is correct and up to date, ask your accountant for a review. It is a 30-minute exercise to verify and gives you certainty for the next bank check or compliance request. Get in touch with Kinore and we will run through your RBO position, your CRO filings, and the wider compliance picture for your company in a single conversation.
Frequently asked questions about the Irish RBO
Is the RBO filing public?
No. Beneficial ownership data is held in a secure register and is accessible only to designated authorities (Revenue, the Garda, the CRO, financial institutions, and certain regulated professionals) for AML purposes. Members of the public cannot access the register following a 2022 Court of Justice of the European Union ruling that limited public access to beneficial ownership registers across the EU.
Do I have to file with the RBO if my company is dormant?
Yes. Every company registered under the Companies Act 2014 is required to file, regardless of trading status. A dormant company that has natural-person beneficial owners must still complete the initial filing within five months of incorporation and update as circumstances change.
What is a Verification of Identity Number (VIN)?
A VIN is a unique identifier issued by the RBO to non-Irish-resident beneficial owners who do not have a PPS number. The application is made through the RBO portal, supported by a notarised copy of an official identity document and proof of address. The VIN then serves as the verification credential for that individual on the RBO register going forward.
How quickly do I need to update the RBO if a shareholder changes?
Within 14 days of the change taking effect. The same 14-day deadline applies to changes in beneficial owner details (for example, an address change) or to anyone ceasing to be a beneficial owner.
Can my accountant file the RBO for me?
Yes. Many Irish accountants, including Kinore, file and maintain the RBO for clients as part of routine company secretarial services. The work is straightforward when the underlying data is clean, and your accountant takes the calendar tracking and form-filling off your plate.
