Tax Disputes (Tax Team)

The Practice

Arthur Cox has extensive experience in tax disputes. The Tax Disputes group is made up of members of our Litigation and Dispute Resolution group (one of the largest in Ireland) and our leading Tax practice. The group works on an integrated basis with the other groups in the firm and advises on all tax disputes matters. The combination of litigators and tax lawyers is a highly effective means of conducting a tax dispute as it combines an in depth technical and policy-based analysis of the relevant tax issues with the appreciation of strategy, tactics and process that are second nature to a litigator.


The tax disputes group provides a full range of services for disputes relating to all taxes including:

  • Corporation tax and capital gains tax disputes with the Revenue Commissioners
  • Rates cases against the Commissioner for Valuation and local authorities
  • Contractual disputes in relation to tax deeds and tax warranties
  • Indirect taxes


The tax disputes team has a wealth of experience drawn from experience litigating, arbitrating and resolving tax disputes relating to all taxes including corporation tax and capital gains tax disputes for large corporate and financial institutions; tax related disputes arising from corporate transactions; indirect tax disputes with the Revenue Commissioners including VAT, stamp duty and other indirect taxes.

In addition, the team has significant experience in advising clients on all aspects in respect of rates. The team has represented clients in a number of high profile cases before the Valuation Tribunal and High Court including acting for the Minister for Communications in a rates matter concerning the Metropolitan Area Networks broadband scheme, PIAB before the Valuation Tribunal and on a case stated to the High Court and NTR in respect of rates issues concerning Westlink and the Dundalk By-pass.

The tax disputes team is co-ordinated by Eve Mulconry, a Litigation and Dispute Resolution partner and Fintan Clancy, a Tax partner.
