What is CRO (Companies Registration Office)?
The Companies Registration Office is Ireland's company registry, equivalent to the UK's Companies House. The CRO holds the public record for every Irish company including directors, shareholders, accounts, and annual returns. Filings are made via CORE at core.cro.ie.

Form B1 is the annual return Irish companies must file with the CRO each year. It confirms key company details (directors, shareholders, registered office) and is accompanied by financial statements (or abridged accounts for small companies). Late filing triggers loss of audit exemption for two years and €100 penalty plus €3 per day.
An Irish private limited company (Ltd, formerly LTD or Limited By Shares) is the most common business entity in Ireland.
