Why Use a Registered Office Address Service?
Every Irish company must have a registered office in Ireland, where official post and legal documents can be delivered. It's shown on the public CRO register, so many owners use a service address instead of their home. Changing it means filing Form B2 with the CRO within 14 days.
What the registered office is for
It's the company's official address. Letters from the CRO and Revenue are sent there, and legal documents can be served on the company by leaving them there. It must be in Ireland and able to receive post.
Why not use your home address?
- The address is shown on the public CRO register, so anyone can see it.
- Official letters with deadlines can arrive while you're away.
- Moving house means changing the company's address too.
CRO, Revenue and official post scanned and emailed, with urgent letters flagged.
How to change it
The directors approve the new address and the company files Form B2 on CORE within 14 days. There's no CRO fee. The change takes effect only when the CRO registers the form, so documents sent to the old address until then still count as delivered. Tell Revenue separately.
The Startup Shop is a CRO-approved Registered Office Agent. When you take our registered office service, the B2 names us as your agent, and we prepare and file it for you as part of setting it up.
What it doesn't change
Directors' own details on the CRO register are a separate matter from the company's registered office. Ask us if you want to understand what's shown about each director.
