Starting a business in Ireland can be a rewarding endeavor thanks to the country’s competitive tax regime, English-speaking workforce, access to the European Union, and strong legal and regulatory framework. Whether you’re an Irish resident or an international entrepreneur, this step-by-step guide will walk you through everything you need to register a company in Ireland in 2025.

Step 1: Choose the Right Business Structure

The first and most critical step is to determine the appropriate company type for your needs. The most common structure for businesses in Ireland is a Private Company Limited by Shares (LTD), but other options include:

• Designated Activity Company (DAC) – suitable for companies with specific objects

• Company Limited by Guarantee (CLG) – used primarily by charities and non-profits

• Public Limited Company (PLC) – for companies planning to list shares publicly

• Sole Trader or Partnership – for smaller, less complex operations

Most small to medium-sized businesses choose an LTD company due to its flexible structure and limited liability protection.

Step 2: Pick a Company Name

Your company’s name must be unique and distinguishable from existing companies registered in Ireland. The name cannot be too similar to another business or contain restricted or offensive words.

How to Check:

• Use the Company Search tool on the Companies Registration Office (CRO) website to verify name availability.

• Make sure your name reflects your business activities and is easy to remember.

Tip: If your name is similar to another company, you may be asked to add extra words or a distinguishing term.

Step 3: Decide on Directors and Secretary

Irish law requires:

• At least one director, who must be a resident of the European Economic Area (EEA). If no director is EEA-resident, you must purchase a Section 137 Non-Resident Director Bond.

• A Company Secretary, responsible for ensuring compliance with statutory obligations. The director can act as the secretary only if there are multiple directors.

Each officer must be over 18 and not disqualified from acting as a company director.

Step 4: Choose a Registered Office Address

Every Irish company must have a physical registered office in Ireland. This is where all legal documents and official correspondence will be sent.

If you don’t have a business premises in Ireland, you can use a virtual office service, which many company formation agents and solicitors provide.

You can also list a business address (different from the registered office) for public correspondence and trading purposes.

---

Step 5: Decide on Shareholders and Share Capital

You’ll need at least one shareholder, who can also be a director. You’ll need to determine:

• The amount of authorized and issued share capital

• The number and class of shares (usually ordinary shares)

• The ownership percentages

The minimum issued share capital is typically €1, though higher amounts are common depending on your business model.

---

Step 6: Prepare Your Company Constitution

For a Private Company Limited by Shares (LTD), the Constitution is a single document that outlines the rules governing the company. It includes:

• Company name

• Statement of liability

• Rules for directors and meetings

• Share capital clauses

The Companies Act 2014 provides a default model constitution, but you can amend it as needed. Legal professionals or formation agents usually assist in drafting this document.

---

Step 7: Complete and Submit Form A1

Form A1 is the key incorporation form and includes:

• Company name

• Details of directors and secretary

• Registered office address

• Company activity (NACE code)

• Share capital and ownership

You’ll submit Form A1 along with your Constitution to the CRO, either electronically through CORE (CRO Online Registration Environment) or via a formation agent.

Step 8: Pay the Registration Fee

As of 2025, the CRO filing fee for electronic submission is typically €50. Paper filings cost more and take longer to process.

Most people opt to file online or through a third-party provider for speed and efficiency.

---

Step 9: Wait for Your Certificate of Incorporation

Once your submission is approved, the CRO will issue a Certificate of Incorporation, which confirms your company legally exists. This document includes:

• Company name

• Company number

• Date of incorporation

At this point, your business can legally trade in Ireland.

Processing time is usually 3 to 5 working days if submitted correctly online.

---

Step 10: Register with Revenue (Tax Authorities)

After incorporation, you must register with the Revenue Commissioners for:

• Corporation Tax

• VAT (if you expect turnover above the VAT threshold)

• Employers’ PAYE/PRSI (if you plan to hire staff)

You can register for these taxes online via Revenue Online Service (ROS). You’ll need:

• CRO number

• Company details

• Bank account information

• Description of business activities

---

Optional but Recommended Steps

Open a Business Bank Account

Once you receive your Certificate of Incorporation and Tax Registration Number, open a business bank account in your company’s name. Most banks will require:

• Certificate of Incorporation

• Constitution

• Personal ID and proof of address for directors

• Proof of Irish business activity

Hire an Accountant or Company Secretary

To stay compliant with Irish law, you must maintain proper accounting records and file annual returns. Many companies outsource this to a professional accountant or company secretarial service.
