Professional registered office address and company correspondence in Ireland

An Irish company’s registered office is its official address for CRO correspondence and legal notices. When that address changes, the company must approve the new location and notify the CRO rather than relying on postal forwarding or an informal change with an accountant.

StartCompany.ie’s €100 change-of-registered-office service prepares the Form B2 update. A separate €300-per-year registered office service is available where the company needs a professional Irish address.

What makes an address suitable

The registered office must be a physical place in Ireland. It does not have to be the trading premises, but the company must be able to receive CRO correspondence and formal notices reliably at that location.

Using a director’s home address places that address on the public register. A professional service can improve continuity and privacy, but it does not by itself prove tax residence, operational substance or permission to use the address for every commercial purpose.

Board record and Form B2

The company should record the effective date and new address, then file Form B2. The CRO identifies B2 as the form for a registered-office change, with the change generally notified within 14 days.

Use the complete postal address and confirm that the provider has authorised its use. A filing made without a reliable mail-handling arrangement can expose the company to missed notices.

Other records to update

After the CRO record changes, review Revenue, bank, insurer, licences, contracts, invoices, website disclosures and stationery. Some use a correspondence or trading address rather than the registered office and therefore need a separate decision.

Keep evidence of the old and new arrangements and tell advisers where statutory books are held if that location also changes.

  • Approve the new physical Irish address.
  • File Form B2 within 14 days.
  • Confirm mail receipt and forwarding.
  • Update tax, banking and commercial records as appropriate.
  • Review public-address privacy implications.

How StartCompany.ie helps

Our €100 service prepares the registered-office change from the company details and effective date supplied. It is suitable where the company already has the new address and needs the corporate update handled correctly.

Where no suitable Irish address is available, order the professional registered office service first so the address and filing can be coordinated.
