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

Step 2: Choose a Company Name

Your company name must be unique, not misleading, and 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 (EEA resident) and a company secretary.

Step 4: Register Your Company with the CRO

This involves completing a Form A1 and submitting your company constitution. Once approved, you will receive your Certificate of Incorporation.

Step 5: Register for Taxes with Revenue

After incorporation, you must register for Corporation Tax, VAT (if applicable), and PAYE/PRSI.

Step 6: Open a Business Bank Account

A limited company must have its own bank account. 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
• Maintaining proper bookkeeping records
