Tax litigation is a standout area for Pérez Alati, Grondona, Benites & Arntsen, which handles contentious matters at federal, municipal and provincial level, including adverse changes in tax rules and tax authority claims. The team will also take on tax planning and transactional work, including contractural protection against tax contingencies, tax due diligence and post-acquisition tax planning. Tax-free corporate reorganisations, debt restructurings and asset transfers are covered too. Veteran tax litigation lawyer Manuel Benites, who also has a strong transactional practice, co-leads the team alongside tax law and litigation expert Luis Marcelo Núñez; customs litigation specialist Andrés Galíndez; and Facundo Fernández Santos, who covers transfer pricing and transactional matters. Counsels Matías Corte (who focuses on tax disputes); Germán Martín Quirán (an expert in customs law); and Cristina Di Benedetto (who handles hydrocarbons royalty claims and tax litigation) provide solid second-line support.
