How to Change Your Company Name in Ireland

Quick answer

An Irish company changes its name by special resolution of its members, with the approval of the Registrar. You file Form G1Q with an amended constitution and the CRO fee (€50 on CORE). The new name takes effect when the CRO issues a certificate of incorporation on change of name.

The steps

  1. Check the name. Search the CRO register for identical or very similar names. The Registrar can refuse a name that's too like an existing one, or that's offensive or suggests state sponsorship.
  2. Pass a special resolution. At least 75% of the votes cast by members must approve. Most small companies use a written resolution signed by all members.
  3. Amend the constitution. The constitution is updated to show the new name.
  4. File Form G1Q. The G1Q, the amended constitution and the fee go to the CRO. Filing on CORE costs €50, compared with €100 on paper.
  5. Receive the certificate. The CRO emails a certificate of incorporation on change of name. The new name takes effect from then.

What our €149.99 service covers

We check the proposed name on the CRO register, prepare the written special resolution and the amended constitution, file the G1Q on CORE once signed and send you the new certificate. The €50 CRO fee is added at cost. If the CRO refuses the name, we tell you why and help you choose another.

What stays the same

The company number, its contracts, bank accounts and tax registrations all continue. It's the same company with a new name.

What to update afterwards

  • Revenue, your bank, insurers and key suppliers.
  • Letterheads, invoices, email signatures and your website, which must show the registered name.
  • Any business name registered with the CRO that you no longer use.
