LTD Co. Set up Guide

If you're thinking about setting up a limited company in Ireland, you're making a move that can offer greater tax efficiency, limited liability, and long-term growth potential.

This guide walks you through each step — from registering your company with the Companies Registration Office (CRO) to understanding your tax obligations with Revenue — so you can start your business with confidence.

Whether you're currently a sole trader or starting from scratch, setting up a limited company is often the next logical step as your business grows.

Step 1: Understand What a Limited Company Is

A limited company is a separate legal entity from its owners (directors and shareholders). This means:

• The company is responsible for its own debts
• Your personal liability is limited
• The business continues independently of the owner

This structure provides more protection compared to operating as a sole trader.

Step 2: Choose a Company Name

Your company name must be unique, not already registered with the CRO, not misleading, and must include “Limited” or “Ltd” at the end.

👉 Tip: Keep it simple, professional, and relevant to your business.

Step 3: Appoint Directors and a Company Secretary

To set up a company in Ireland, you must have at least one director (must be EEA resident or have a bond) and appoint a company secretary (can be another person or a company).

The director is legally responsible for managing the company and ensuring compliance.

Step 4: Register Your Company with the CRO

You must register with the Companies Registration Office (CRO). This involves completing a Form A1, providing details of directors/shareholders, and submitting your company constitution. Once approved, you receive your Certificate of Incorporation.

Step 5: Register for Taxes with Revenue

After incorporation, you must register your company with Revenue. This typically includes Corporation Tax, VAT (if applicable), and PAYE/PRSI if you plan to pay yourself or employees.

👉 This step is crucial to ensure you remain compliant from day one.

Step 6: Open a Business Bank Account

A limited company must have its own business bank account. You will usually need your Certificate of Incorporation, constitution, and ID for directors. Keeping finances separate is essential for proper accounting.

Step 7: Understand Your Ongoing Obligations

Running a limited company comes with ongoing responsibilities, including filing annual returns with the CRO, preparing annual financial statements, paying corporation tax, and maintaining proper bookkeeping records.

👉 This is where many business owners benefit from having an accountant involved early.
