Where a company or person is trading in Ireland under anything other than their natural name, they must register with the Companies Registration Office.
The company / individual themselves must decide how they want to register. However, they must have a place of business in Ireland before their application can be accepted by The Companies Registration Office.
Registering a Company
A company is a legal form of business organisation. It is a separate legal entity and, therefore, is separate and distinct from those who run it.
A Form A1 should be submitted along with a constitution. Company incorporation (for an LTD company) can be completed online.
Registering a Foreign Company (External Company)
Any company which is incorporated outside the State and establishes a branch in the State must be registered with the CRO under the Companies Act 2014.
The registration must take place within one month of the establishment of the branch in the State.
Companies from a Member State of the EEA file Form F12 to register.
Companies from a non-EEA member state file Form F13 to register.
Registration of Business Name
To register a business name, submit the appropriate form, along with the registration fee (€40 for paper filing/€20 for electronic filing), to the CRO within one month of adopting the business name. Forms are available here or alternatively can be completed online.
