An Irish LTD company is one of the most common company types used by founders in Ireland. It is flexible, familiar to banks and suppliers, and suitable for many small businesses, agencies, consultants, ecommerce companies and technology businesses.
Before registering, you should understand the main requirements: company name, Form A1, registered office, directors, secretary, shareholders, share capital, constitution, beneficial ownership and tax registration.
1. Company Name
Your company needs a name that the CRO can accept. A name can be delayed or refused if it is too similar to an existing company, misleading, offensive or includes restricted wording without the right approval.
A good name should be distinctive, practical for customers, and available as a domain where possible. Have at least one backup name ready before filing. You can start with our company name check.
2. Form A1 Incorporation Details
The CRO states that Form A1 requires details such as the company name, registered office, secretary, directors, consent to act, subscribers and share details. It also incorporates a declaration that the Companies Act requirements have been complied with and states the activity the company is being formed to carry on.
This means your formation is only as clean as the information provided. Director details, secretary details, shareholder details and shares should be decided before the filing is prepared.
3. Irish Registered Office Address
Every Irish company needs a registered office address in Ireland. This is the official address used for CRO correspondence and legal notices. It should be a reliable physical address in the State, not simply a general contact email or website address.
If you do not have a suitable Irish business address, a registered office service can make the setup cleaner. This is especially useful for non-resident founders, home-based founders and companies that want to keep a private residential address away from public-facing records where possible. See our registered office address Ireland page.
4. Directors
An LTD can be formed with one or more directors. Directors are responsible for managing the company and making sure key legal and filing obligations are handled. If the company is set up with one director, the company secretary must be a different person or body corporate.
For international structures, director residency is important. CRO guidance says an Irish company should have at least one EEA-resident director unless the company holds a valid Section 137 bond or has another applicable exemption. If your directors are outside the EEA, review our Section 137 bond Ireland guide before filing.
5. Company Secretary
Every Irish company needs a company secretary. The secretary helps with statutory records, filing discipline, annual returns and company administration. A common mistake is assuming that a sole director can also act as secretary; for a single-director LTD, that does not work.
If you do not have a suitable person for the role, use a company secretary service. This is often cleaner than appointing someone who cannot support filings or company records.
6. Shareholders and Share Capital
Shareholders own the company. At incorporation, the first shareholders, also called subscribers, take the initial shares. A simple founder-owned company may have one or two shareholders and ordinary shares. If there are investors, holding companies, nominee arrangements or unusual rights, get advice before filing.
The share structure should match the commercial agreement between founders. Changing it later is possible, but a clean starting point saves time and avoids disputes.
7. Company Constitution
The constitution is the company's internal rulebook. It should match the company type and the share structure. Formation packages normally include preparation of the constitution, but the founder still needs to make sensible decisions about ownership and control.
8. PPSN, IPN or VIF Requirements
Directors and relevant parties may need to provide identity-number information. Irish residents often use a PPSN. Non-residents may need an IPN or VIF route where they do not have a PPSN. This can affect timing, so prepare early.
Read our PPSN, IPN and VIF guide if any director or beneficial owner is outside Ireland.
9. RBO Registration
After incorporation, most companies must register beneficial ownership information with the RBO. The RBO states that newly incorporated entities have five months from incorporation to register beneficial ownership. This filing is separate from CRO incorporation.
For a simple founder-owned company, the beneficial owner position may be straightforward. For a layered ownership structure, take advice before filing. Our RBO registration Ireland guide explains the process.
10. First Annual Return
CRO guidance says the first annual return is due exactly six months after incorporation and does not require financial statements. It is still a real filing deadline, and missing it can create unnecessary penalties and compliance stress.
If you want the early deadline handled for you, choose a package that includes first annual return support or use our annual returns service.
11. Tax Registration
Company incorporation is separate from tax registration. Revenue guidance says a new company must have a CRO number before registering for tax. Depending on the business, registration may include Corporation Tax, VAT, PAYE, RCT or other relevant tax heads.
New directors should speak with an accountant or tax agent early, especially where the company has non-resident directors, overseas customers, employees, VAT questions or management and control issues. Start with our Irish company tax registration checklist.
