Companies in Ireland are registered by the Companies Registration Office, in Irish An Oifig um Chlárú Cuideachtaí (CRO), an office of the Department of Enterprise, Tourism and Employment and the statutory repository of public information on Irish companies, business names and limited partnerships. Filing and searching are done through its online portal, CORE. Beneficial ownership is held in a separate register, the Register of Beneficial Ownership (RBO), whose data — unlike the company register — is no longer openly searchable by the general public.

The official company register in Ireland

The register of companies is maintained by the Companies Registration Office (An Oifig um Chlárú Cuideachtaí, CRO) under the Companies Act 2014, and operates under the aegis of the Department of Enterprise, Tourism and Employment. Incorporation, annual returns and all statutory notifications are filed electronically through CORE (Companies Online Registration Environment), and the register is searchable from cro.ie.

The CRO in fact keeps three distinct registers, which is the key to understanding how Irish businesses are recorded:

  • The register of companies — every body corporate formed under the Companies Act 2014, plus external companies with a branch in the State.
  • The Register of Business Names — maintained under the Registration of Business Names Act 1963. A sole trader, a partnership or a company that trades under a name other than its own true name must register that name. This is the closest Ireland comes to a register of individual entrepreneurs: it records the trading name and the person behind it, but it confers no legal personality and no protection of the name.
  • The register of limited partnerships — partnerships formed under the Limited Partnerships Act 1907.

Two further registrars sit alongside the CRO. The Registrar of Beneficial Ownership (RBO) at rbo.gov.ie keeps the central register of the natural persons who ultimately own or control Irish companies and industrial and provident societies. The Registrar of Friendly Societies (Cláraitheoir na gCara-Chumann) at rfs.gov.ie keeps the registers of industrial and provident societies (co-operatives), friendly societies and trade unions. Certain regulated fund vehicles — the Irish Collective Asset-management Vehicle and the investment limited partnership — are authorised and registered by the Central Bank of Ireland rather than by the CRO.

An ordinary partnership formed under the Partnership Act 1890 is not registered anywhere, and a sole trader using only his or her own surname need not register at all; both, however, must register with the Revenue Commissioners for tax purposes.

Legal forms that can be registered in Ireland

English is an official language of the State and the Companies Act 2014 names the corporate forms in English, so no translation is required; Irish-language equivalents may be used in a company name if the constitution provides for it.

Company types registered with the CRO:

  • Private company limited by shares (LTD) — the standard Irish company since 2014: a one-document constitution, unlimited capacity rather than an objects clause, one to 149 members, and the only type permitted to have a single director provided it has a separate secretary. Members’ liability is limited to the amount unpaid on their shares.
  • Designated activity company limited by shares (DAC) — a limited company that retains a memorandum stating specific objects; used where a company must be seen to be restricted to a defined activity, for example joint ventures and certain regulated or trustee businesses. Requires at least two directors.
  • Designated activity company limited by guarantee having a share capital (DAC) — the same objects-restricted structure but with members contributing both share capital and a guarantee.
  • Company limited by guarantee (CLG) — no share capital; members guarantee a nominal amount on winding up. The standard vehicle for charities, clubs, management companies and other not-for-profit bodies. Requires at least two directors.
  • Public limited company (PLC) — may offer securities to the public and be listed; subject to a statutory minimum issued share capital and to at least two directors. The form used by large and listed businesses.
  • Private unlimited company (ULC) — has a share capital but its members have unlimited liability; used where confidentiality of a group structure or an unlimited guarantee to creditors is required.
  • Public unlimited company (PUC) — an unlimited company with a share capital that may offer securities to the public.
  • Public unlimited company without share capital (PULC) — an unlimited public company whose members are liable without limit and which has no share capital.
  • Investment company — a public limited company with variable capital formed under Part 24 of the Companies Act 2014 for collective investment, authorised by the Central Bank of Ireland.
  • Societas Europaea (SE) — the European public limited-liability company, registered in the State under the EU SE Regulation and capable of transferring its seat to another Member State.
  • External company (branch) — a company incorporated outside the State that establishes a branch in Ireland must register that branch with the CRO under Part 21 of the Companies Act 2014 and file the parent’s accounts.
  • European Economic Interest Grouping (EEIG) — a cross-border cooperation vehicle with unlimited member liability, registered with the CRO where its official address is in the State.

Other business forms and where they are registered:

  • Limited partnership — one or more general partners with unlimited liability and limited partners liable only to the extent of their contribution; registered with the CRO under the Limited Partnerships Act 1907.
  • Investment limited partnership — a regulated fund partnership authorised and registered by the Central Bank of Ireland.
  • Irish Collective Asset-management Vehicle (ICAV) — a corporate fund vehicle registered and authorised by the Central Bank of Ireland rather than by the CRO.
  • General partnership — governed by the Partnership Act 1890, with joint and several unlimited liability; not registered as an entity, though its trading name may appear in the Register of Business Names.
  • Sole trader — an individual carrying on business personally, with unlimited liability; no entity registration, only a business name registration where the trading name differs from the person’s own name.
  • Industrial and provident society (co-operative) — a member-owned society registered with the Registrar of Friendly Societies under the Industrial and Provident Societies Acts.
  • Friendly society and trade union — mutual and representative bodies registered with the Registrar of Friendly Societies under their own legislation.

Anyone working from pre-2015 material should note that the Companies Act 2014 replaced the old private company limited by shares: existing companies were converted either to the new LTD or to a DAC, the memorandum and articles were replaced by a single constitution for LTDs, and the company limited by guarantee with a share capital ceased to exist as a form in its own right, becoming a designated activity company.

Information available from the register

A free company search on CORE identifies any registered entity and gives its core statutory data: the registered name and company number, the registered office address, the company type, the date of incorporation, the current status — for example normal, strike-off listed, dissolved or in liquidation — the company’s annual return date, and the list of every submission it has filed with the register. Because the submission list is itself public, it shows at a glance whether a company is up to date with its annual returns and what has changed and when.

The substantive detail sits in the filed documents, which are public. From them the register discloses the company’s constitution and any alteration to it, the identity of directors and secretaries with their dates of appointment and resignation, their usual residential addresses, dates of birth, nationality and other Irish directorships, the issued share capital and its allotments, the members and their shareholdings as stated in the annual return, resolutions of the members, and the register of charges — the mortgages and charges created over the company’s assets and their satisfaction.

Financial statements are public in Ireland, which sets it apart from many non-European registers. Irish companies must annex financial statements to the annual return on Form B1, and those accounts are available to anyone. Small and micro companies may file abridged financial statements and most may claim audit exemption if their annual returns are filed on time, while a company limited by guarantee and a public limited company face fuller requirements — so the depth of the accounts on file depends on the company’s size and type rather than on any choice about disclosure.

What the register does not disclose

Beneficial ownership is effectively closed to the public. Irish companies and industrial and provident societies must file the names, dates of birth, nationality, addresses and nature and extent of the interest of their beneficial owners with the RBO, but the search facility is restricted: access is granted to competent authorities and, on a limited basis, to designated persons within the meaning of the anti-money-laundering legislation. A member of the public can see no more than very limited data such as the initials of a beneficial owner and the year of birth. The separate Central Register of Beneficial Ownership of Trusts is operated by the Revenue Commissioners and is likewise not open to general search.

Identity data used for verification is never published. A director filing an annual return must supply a PPS number, or a CRO-issued Identified Person Number where no PPS number exists, and the CRO states that its staff do not see the PPS number itself — it is verified against Department of Social Protection records and not retained on the public file.

The register also holds no information on tax, employment or licensing: tax registration and returns are matters for the Revenue Commissioners, and sectoral authorisations are held by the relevant regulator. Ordinary partnerships and unregistered sole traders leave no entity record at all, so their existence cannot be confirmed from the CRO.

Documents that can be obtained from the register

Documents and certificates are ordered through CORE, and most filed documents are available as scanned or digital images.

  • Certificate of incorporation — conclusive evidence that the company is registered, stating its name, number and date of incorporation. Issued digitally on registration and available afterwards as a duplicate; required for banking, tenders, property transactions and applications to regulators.
  • Certificate of incorporation on change of name — evidences a change of company name while preserving continuity of the company number, so contracts made under the former name can be traced.
  • Constitution (or memorandum and articles of association for older companies) — the company’s governing document, showing capacity, share rights, directors’ powers and meeting procedure. Essential for verifying authority to sign.
  • Company printout — a consolidated extract of the register entry: officers, registered office, share capital, annual return history and status. The usual first document in Irish due diligence.
  • Annual return (Form B1) with financial statements — the annual statutory return giving officers, share capital, shareholders and shareholdings, with the balance sheet, profit and loss account and directors’ and auditor’s reports annexed.
  • Officer notifications (Forms B10, B69 and related filings) — appointments, resignations and changes in the particulars of directors and secretaries, used to establish who could bind the company at a given date.
  • Share and capital filings (Forms B5, B4 and related) — allotments of shares, increases in capital and changes in share particulars, showing how ownership has moved over time.
  • Charge documents (Forms C1, C6 and C7) — the particulars of a mortgage or charge created by the company and the notice of its satisfaction or release. Central to lending, security reviews and asset purchases.
  • Resolutions (Forms G1 and G2) — special and ordinary resolutions of the members that must be delivered to the register, for example changes of name, alteration of the constitution or re-registration as another company type.
  • External company filings — the constitutive documents, particulars of directors and the parent company accounts filed on registration of an Irish branch of a foreign company.
  • Certificate of registration of a business name — the certificate issued for each registered business name, which must be displayed at the principal place of business; the underlying registration shows the person or company behind the trading name.
  • Liquidation, receivership and strike-off filings — appointments of liquidators and receivers, statements of affairs and notices leading to dissolution, which reveal whether an entity is still trading lawfully.

Frequently Asked Questions

What is the official business register in Ireland?

It is the register kept by the Companies Registration Office (An Oifig um Chlárú Cuideachtaí, CRO), an office of the Department of Enterprise, Tourism and Employment, which holds the registers of companies, business names and limited partnerships. Filing and searching are done on its CORE portal.

Is the Irish company register free to search?

Basic company data — name, number, registered office, type, status, incorporation and annual return dates and the list of filed submissions — can be searched free on CORE. Company printouts, certificates and copies of filed documents are chargeable products.

Are Irish companies’ accounts public?

Yes. Financial statements are annexed to the annual return on Form B1 and are open to inspection by anyone. Small and micro companies may file abridged accounts and many qualify for audit exemption when their returns are filed on time, so the level of detail varies with company size and type.

Can I see who beneficially owns an Irish company?

Not as a member of the public. Beneficial ownership data is filed with the Register of Beneficial Ownership, but the search facility is open only to competent authorities and, on a restricted basis, to designated persons under the anti-money-laundering legislation; the public sees only very limited data such as initials and year of birth.

Do sole traders and partnerships appear on the register?

Only indirectly. A sole trader or partnership trading under a name other than its own true name must register that name in the Register of Business Names, which discloses who is behind the name. An ordinary partnership itself, and a sole trader using only his or her own surname, are not registered as entities.

Where does a foreign company register a branch in Ireland?

With the CRO, under Part 21 of the Companies Act 2014. An external company establishing a branch must register the branch, file its constitutive documents and particulars of its directors, and thereafter deliver the accounts of the parent company to the Irish register.
