Register of Beneficial Ownership (RBO) Ireland: What Companies Must Record

If you run or advise an Irish company, you may be asked whether it has filed on the Register of Beneficial Ownership (RBO). The RBO is Ireland's central register of the natural persons who ultimately own or control companies, and Irish-incorporated companies have recording and filing duties. This guide explains what companies must record, who must file, the deadlines the official pages state and what the pages say about penalties and access. It is a plain-English overview, not legal advice. For the wider concept of identifying owners in client due diligence, see our guide to ultimate beneficial ownership for accountants.

What the RBO is

According to the RBO's own "About" page, the RBO is the central repository of information on the natural persons who are the beneficial owners or controllers of companies and industrial and provident societies, drawn from the information those entities hold in their own registers. The page names the legal basis as Article 30 of the Fourth Anti-Money Laundering Directive and S.I. No. 110 of 2019, which established the RBO and replaced S.I. No. 560 of 2016. It also lists S.I. No. 308 of 2023, which restricted public access to a "legitimate interest" test, and S.I. No. 406 of 2026, which it says expands legitimate-interest access. The About page also appears to contain a typo in the latter instrument's title, so check the instrument itself.

Who must file

The RBO's FAQ page on beneficial owners (last modified 19 May 2026) says filing applies to companies and industrial and provident societies incorporated in Ireland. It adds several points that are easy to miss:

• Companies listed on a regulated market with equivalent transparency rules are exempt, but their Irish-incorporated subsidiaries are not.
• Sole traders, business names, partnerships and branches are not required to file.
• Other entities such as trusts and investment funds keep internal registers only.
• A parent company cannot be entered as a beneficial owner. Only natural persons can be.

S.I. No. 110 of 2019 on the Irish Statute Book similarly refers to relevant entities incorporated in the State that must keep a beneficial ownership register and file information with the central register, and excludes certain entities listed on regulated markets. Read the instrument or take legal advice if your structure is unusual.

Who counts as a beneficial owner

The RBO FAQ defines a beneficial owner as any natural person who ultimately owns or controls a legal entity, directly or indirectly. The page states that ownership of more than 25% of shares, or control of more than 25% of voting rights, is one test, and gives an example: in a company with 1,000,000 shares, a holder of 250,000 shares does not meet the test but a holder of 250,001 does. Control can also arise through other means, which the page illustrates with a shareholders' agreement, the exercise of dominant influence or the power to appoint senior management. The page says the percentage test should not be the only method used to identify beneficial owners.

If, after exhausting all possible means and where there are no grounds for suspicion, no natural person can be identified, the page says the senior managing officials (which it says include directors and chief executive officers) are recorded instead, and records of the steps taken must be kept. The page repeatedly advises seeking legal advice when you are unsure who the beneficial owners are.

What must be recorded and filed

The RBO's filing page (last modified 21 August 2026) lists the details for each beneficial owner:

• Name, date of birth, PPSN, nationality, residential address and country of residence.
• The nature and extent of the interest held and of the control exercised.
• The company's name and number.
• The dates of entry and cessation as a beneficial owner.
• Details of the presenter filing on the company's behalf.

The page says the name entered must exactly match the name registered to the PPSN with the Department of Employment Affairs and Social Protection, and that the Registrar may reject mismatches. S.I. No. 110 of 2019 says the PPS number is used for verification and is not disclosed in the register.

How filing works

The filing page states that:

• Filing is online only. Paper or manual forms are not accepted and do not satisfy the obligation.
• There are no filing fees.
• Drafts cannot be saved, so have all details ready, and submitted filings cannot be viewed later.
• An officer or employee of the company can complete the filing, or a presenter can file on its behalf, after registering on the RBO Registration Portal.
• Updates and removals use the "Update/Remove" option. Removed shareholdings do not transfer automatically to the remaining owners, so a separate filing is needed.

Our suggestion: assign the task to a named person, such as the person who handles statutory registers. The RBO page does not say the filing must be done by any particular officer, and an officer, an employee or a presenter can file; our guide to company secretary duties covers the wider role of keeping statutory registers.

Deadlines the pages state

The official pages we read give these timeframes:

• New entities: the FAQ page says entities incorporated on or after 22 June 2019 must file within 5 months of incorporation, and S.I. No. 110 of 2019 says new entities file within 5 months of incorporation.
• Changes: the filing page says changes to beneficial ownership must be notified within 14 days of the change to the entity's internal register, covering additions, removals and changes of name or address.
• Annual return: the filing page says no annual return is required.

The FAQ page does not give a deadline for existing entities that need to update their details, so rely on the 14-day rule on the filing page and check the instrument. The official pages also give differing dates for when the central filing requirement began, which is of limited practical relevance today, so we do not state one.

Penalties

The RBO filing page does not describe general penalties. It says paper filings do not meet the obligation and that a beneficial owner who knowingly gives false details may face prosecution or other sanctions. S.I. No. 110 of 2019, as shown on the Irish Statute Book, provides for offences. As we read it, failing to keep a register or to file required information carries a class A fine on summary conviction or, on indictment, a fine of up to EUR 500,000, and continuing contraventions can be separate offences for each day. Officers can also be liable where an offence is committed with their consent or connivance. The page does not describe later amendments, so confirm current penalties before relying on these.

Access and discrepancies

The About page says public access was replaced by a "legitimate interest" test under S.I. No. 308 of 2023, with full access kept for competent authorities, and links to an FAQ titled "Search facility access on the RBO Register only available to Designated Persons". The same pages refer to reporting of discrepancies, though we could not read that page's content. For firms carrying out client due diligence, our guide to AML training under section 54 explains how staff awareness fits into the wider obligations.
