Tax

Key Contact

Our tax department is significantly the largest tax practice group amongst Irish law firms with over 40 lawyers and tax advisers and 20 partners and tax principals.  We advise on the tax aspects of transactions as part of a multi-disciplinary team with lawyers from other groups within the firm.

The size of our tax practice provides us with an ability to specialise, which distinguishes us from the tax departments of other Irish law firms.  This ability to specialise has become more important in recent years with global and European tax initiatives having a fundamental impact on both our current and future tax laws, increasing the complexity and range of issues that our tax advice has to cover. 

We advise many leading domestic and international corporations and financial institutions doing business in and from Ireland.  We focus on the timely delivery and implementation of integrated leading-edge tax advice. Our philosophy is ‘can do’ – if there is a solution we will find it.

We are consistently ranked as the leading tax law firm in Ireland by the European Legal 500, Chambers Global, World Tax and International Tax Review. 

Experience Highlights

Our tax lawyers advise clients across a broad range of sectors, including life sciences, technology, consumer goods, finance and insurance, IT, FinTech, real estate, energy and utilities and manufacturing.

Advising clients on internal reorganisations and restructurings is a core part of our practice.  Due to the impact of various recent OECD initiatives, EU measures, US tax reform and changes to Ireland’s corporate residency and transfer pricing rules, we have advised on a large number of reorganisations for our clients in recent years.

We have also advised on the tax aspects of a significant number of both public and private mergers and acquisitions (including certain buy-outs of high-value minority positions and transactions to transfer high-value family-owned businesses to the next generation).

Some of our recent transactions include advising:

  • Revenue audits and tax controversy matters.
  • A number of clients who were seeking advance pricing agreements with the Irish Revenue Commissioners and numerous different jurisdictions.
  • A number of Fortune 500 multinationals including many in the technology, life sciences and food and beverages sectors on IP reorganisations.
  • A number of clients, with our Competition and Litigation colleagues, on stand-alone State aid matters
