Changing Your Registered Office: Form B2

Quick answer

To change an Irish company's registered office, the directors approve the new address and the company files Form B2 on CORE within 14 days. There's no CRO fee, and the change takes legal effect only once the CRO registers the form.

When the change takes effect

The new address becomes the registered office only when the CRO registers the B2. Until then, documents sent to the old address recorded at the CRO are treated as properly served on the company, so file promptly.

Using a registered office agent

Many companies use an accountant's or service provider's address. If the provider is an approved Registered Office Agent, the B2 names the agent and the company consents to the appointment.

Who else to tell

  • Revenue, which doesn't take the address from the CRO automatically.
  • Your bank and insurers.
  • Your letterheads, website and invoices, which must show the registered office.

If the company keeps its statutory registers somewhere other than the registered office, that location is notified separately on Form B3.
