Tax professionals in Ireland

In Ireland, preparing and filing tax returns is not a closed licensed profession, so consumers benefit from verifying that a practitioner holds a recognised qualification and is a current member in good standing of an accredited professional body. Agents who file returns on behalf of clients are required to register with Revenue under the Tax Agent Identification Number (TAIN) system.

Before you hand over documents, confirm the preparer’s credentials against the official source.

  1. Step 1: Check that the practitioner holds a current professional qualification by searching the relevant body's online register — for example, the Chartered Accountants Ireland member directory at charteredaccountants.ie/find-a-chartered-accountant for ACA holders, or contact the Irish Tax Institute directly to confirm Chartered Tax Adviser (CTA) membership status.

  2. Step 2: Ask the practitioner whether they hold a current practising certificate from their professional body; practitioners providing tax compliance services to the public for a fee are generally required to hold one and to carry professional indemnity insurance.

  3. Step 3: For agents who file returns on behalf of clients, ask for their TAIN (Tax Agent Identification Number) — practitioners regularly filing with Revenue on clients' behalf must be registered under the TAIN system, which you can reference at revenue.ie/en/online-services/services/tax-professionals/index.aspx.
