CRO Form A1 is the core incorporation application for a new Irish company. It is not simply a name-registration form. Together with the company constitution, it sets the company's initial record at the Companies Registration Office (CRO): the official registered office, officers, shareholders, issued shares, contact email and activity declaration.
A well-prepared application helps the incorporation process move cleanly. A rushed one can be returned, delay a bank application or create post-incorporation correction work. This guide explains what founders should decide before the filing is prepared. It is general information, not legal, tax or company-secretarial advice for a specific structure.
Quick answer
Form A1 records the proposed name, Irish registered office, email address, directors, secretary, subscribers, shares and proposed activity. An Irish LTD can have one director, but a sole director needs a separate secretary. Prepare the constitution, identity route, share allocation and EEA-director position before the CRO application is submitted.
What Is Form A1?
Form A1 is the CRO's application for incorporation. The CRO says it includes details of the company name, registered office, company email address, secretary, directors and their consent to act, subscribers and their shares. It also contains declarations that the Companies Act 2014 requirements have been met and that the company will carry on the activity described in the application.
For a typical private company limited by shares, often called an Irish LTD, the filing is made with the company constitution. The CRO reviews the documents and, where the application and proposed name are in order, issues a Certificate of Incorporation. Incorporation creates a separate company, but it does not by itself complete tax registration, banking, RBO filing or every operational step required before trading.
What You Need Before Preparing Form A1
- A proposed company name and sensible alternatives.
- A physical registered office in Ireland.
- The company type and a suitable constitution.
- Full details for directors, secretary and subscribers.
- The initial share allocation, classes and nominal value.
- A clear principal activity and appropriate NACE classification.
- PPSN or IPN details for directors where required.
- An EEA-resident director or the appropriate Section 137 bond route.
Make the decisions first, then let the paperwork reflect them. Avoid treating the application as a place to experiment with ownership, titles or a business description. Those choices have legal, tax, banking and practical consequences outside the CRO filing itself.
Company Name: Check It Before You Commit
The company name on Form A1 must exactly match the name in the constitution. The CRO can reject a name that is identical or too similar to an existing company name, misleading, offensive or restricted without the required permission. A name that seems available on a web search is not necessarily suitable for incorporation or free from trade-mark risk.
Use the free company name check before documents are drafted. For an urgent filing, have two or three viable alternatives. The CRO also offers a name-reservation service through CORE, subject to its current fee and conditions.
Registered Office and Company Email
The registered office is the company's formal Irish address. CRO correspondence and legal notices are sent there, and the CRO requires a physical location in the State rather than only a PO box. It does not have to be the trading address, but it must be an address at which the company can reliably receive formal documents.
The company email stated on Form A1 should be monitored. Use an inbox that will survive a founder's absence, staff change or service-provider handover. If you do not have suitable premises in Ireland, arrange a registered office address service before filing.
Directors, Secretary and the EEA Rule
Every company has directors and a secretary. An LTD may have one director, but where there is a single director, that person cannot also be the secretary. The second role must be held by a separate person or an eligible corporate secretary. The officers must consent to act and their personal particulars need to be accurate.
A company generally also needs at least one director resident in the European Economic Area (EEA), unless it qualifies for another statutory route. A common route for a company with no EEA-resident director is a two-year Section 137 bond. It is not a nationality test for shareholders: a non-resident can own all the shares, while the company still needs to satisfy the director-residency condition. See the Section 137 bond guide for the non-resident position.
Identity Details: PPSN, VIF and IPN
A director with an Irish PPSN uses it for relevant CRO filings. A director without a PPSN normally uses the CRO's alternative identity-verification process and receives an Identified Person Number (IPN). Names, dates of birth and identity details should agree with the underlying official documents. Mismatches can slow the filing and later officer changes.
Non-resident founders should prepare this early. Current CRO requirements can change, including rules around verification and witnessing, so use the CRO's latest guidance and see our PPSN, IPN and VIF guidebefore submitting the application.
Subscribers, Shareholders and Share Capital
The subscribers are the people or entities that agree to form the company and take the initial shares. For a simple founder-led LTD, this may be one shareholder taking 100 ordinary shares. In a two-founder business, it may be a clear split such as 50/50 or 60/40. The right answer depends on the founders' commercial agreement, investment plan and advice, not on a template default.
Confirm the share class, number of shares, nominal value and recipient before incorporation. The Form A1, constitution, share certificates and statutory registers should tell the same story. Do not rely on a verbal arrangement where founders have unequal contributions, future vesting, investor rights or a corporate shareholder. Get the structure reviewed before filing.
Activity in the State and NACE Code
The application includes an activity-in-the-State declaration. The CRO requires the general nature of the proposed activity, the appropriate NACE classification, the place or places in Ireland where the activity will be carried on and where the company's central administration will normally be conducted. The company must appear to the Registrar to be going to carry on an activity in the State.
Use a plain, truthful activity description. A software business, professional consultancy, e-commerce retailer and property-holding structure can raise different questions for Revenue, banks, insurers and advisers. A registered office alone is not a substitute for genuine business activity, management or substance where those concepts matter.
Form A1 and the Constitution
The constitution is the company's governing document. For an LTD, it uses the one-document format provided for that company type. Other types, such as DACs and CLGs, have different constitutional requirements. The name and share information must align with Form A1. A general template can be unsuitable when the company has special rights, multiple share classes, investment terms or a non-standard purpose.
Keep an executed copy with the Certificate of Incorporation, initial board records and share certificates after the company is formed. These are not just filing artefacts; banks, investors, accountants and potential buyers may later ask for them.
Common Reasons an Application Needs Attention
- The proposed name conflicts with an existing or restricted name.
- The name, officer details or share details do not match across the application and constitution.
- The address is not a valid physical registered office in Ireland.
- A sole director is also recorded as the only secretary.
- The EEA-director requirement or bond route has not been addressed.
- Identity details do not match the PPSN or IPN record.
- The activity declaration is vague, inconsistent or unsupported by the planned business.
- Founders have not agreed the initial share split before the application is filed.
Practical Form A1 Checklist
- Choose the company type that fits the real business.
- Check the preferred name and prepare alternatives.
- Arrange the registered office and company email.
- Confirm directors, secretary and the EEA-residency route.
- Complete PPSN/IPN identity work for relevant directors.
- Agree subscribers, share classes, numbers and ownership percentages.
- Describe the principal activity and select the NACE classification.
- Review the constitution and Form A1 together before submission.
- After incorporation, start the RBO, tax, banking and first-year filing plan.
What Happens After Form A1 Is Accepted?
Once the CRO incorporates the company, it issues a Certificate of Incorporation and the company exists as a separate legal entity. The work then moves from incorporation to operating and compliance. Keep the company records, issue share certificates, make the beneficial-ownership filing, plan applicable tax registrations, set up banking and diary the first annual return.
Use the post-incorporation checklist and RBO registration guideto map the immediate steps. StartCompany.ie's company formation service prepares the core formation documents and CRO filing, with package options for the address, IPN and non-resident requirements.
