How to Register a Limited Company in Ireland (2026): A Step-by-Step Guide

Setting up a limited company sounds more complicated than it actually is. Most people picture mountains of paperwork and weeks of waiting. In reality, a straightforward Irish company can be incorporated in a few working days, and most of the “hard” part is just knowing what the Companies Registration Office (CRO) expects from you before you file.

This guide walks through exactly what you need, in the order you’ll need it.

What is an LTD company, and is it the right type for you?

The vast majority of Irish businesses register as a private company limited by shares — the LTD. It’s popular for good reason: your personal assets are protected if the business runs into trouble, you can have a single director, and it carries the credibility that comes with “Limited” after your name.

If you’re a freelancer weighing this against staying self-employed, it’s worth reading our guide on sole trader vs limited company first, because the LTD isn’t automatically the right answer for everyone.

Step 1: Choose (and check) your company name

Your name has to be genuinely unique on the register — “too similar” to an existing company is one of the most common reasons a submission gets bounced.

Before you get attached to a name, run it through a free company name check.

We cover the full rules in our guide to choosing a company name, but the short version: avoid names that are near-identical to existing ones, imply state backing, or use restricted words like “bank” or “insurance” without permission.

Step 2: Appoint your directors

Every Irish company needs at least one director.

Here’s the catch that surprises a lot of founders: at least one director must be resident in the European Economic Area (EEA).

If none of your directors live in the EEA, you’re not stuck — you simply put a Section 137 Bond in place instead.

We explain that fully in our guide to registering an Irish company as a non-resident.

Directors must be at least 18 and provide a residential address and verified identity details using a PPSN, or an IPN where they do not have a PPSN.

Step 3: Appoint a company secretary

Every company also needs a company secretary, who is responsible for the company’s statutory filings.

If your company has only one director, the law requires the secretary to be a different person or a corporate secretary.

Many founders use a professional company secretary service so they’re never personally chasing CRO deadlines — more on why that matters in our annual return guide.

Step 4: Sort out shareholders and shares

Shareholders are the owners.

You can be the sole shareholder, or split ownership among a founding team.

Most new companies issue a modest number of ordinary shares, such as 100 shares at €1 each. You don’t need to hand over large sums of capital to start.

If you’re bringing in investors or want to keep tight control, ask us about share classes and the role of a golden share.

Step 5: Provide a registered office and business address

Your company must have a registered office — a real, physical address in Ireland, not a PO box, where official documents can be served.

This address appears on the public register, so many founders prefer not to use their home.

A registered office address or virtual business address solves that neatly.

We compare the two in this guide.

Step 6: File with the CRO

With the above in hand, your incorporation documents, including the company constitution, are submitted electronically to the CRO.

Once approved, you’ll receive your Certificate of Incorporation — the official birth certificate of your company — typically within a few working days.

This is the point where the company legally exists.

Step 7: The bit people forget — after incorporation

Getting the certificate is the beginning, not the finish line.

Within the first few months you’ll usually need to:

• Register for tax with Revenue — Corporation Tax, and possibly VAT and PAYE.
• File your beneficial ownership details with the Central Register of Beneficial Ownership (RBO), generally within five months.
• Diarise your first annual return, due six months after incorporation.

Miss these and you can rack up penalties before you’ve even made your first sale.

The simplest way to do all of this

You can absolutely handle each step yourself.

But most founders would rather spend that time on their business, which is why we bundle the whole process — name check, directors and secretary, registered office, CRO filing and post-incorporation setup — into fixed-price formation packages.
