Tax: The Big Four in Spain

Deloitte Legal

Deloitte Legal’s tax team is lauded by clients for its ‘unique ability to juggle multiple tasks while maintaining the highest quality' of work, as well as its ‘dedicated‘ and ‘hardworking‘ approach to client matters. Clients from a variety of industries, including TMT, banking, and pharmaceuticals, turn to the team for its solid capabilities in cross-border tax matters. The practice is jointly led by managing partner Nicolás de Gaviria, a key contact for the tourism and services industries seeking advice on business and international tasks matters, and Juan Ignacio de Molina, who specialises in transfer pricing, and is often retained by financial services, energy and manufacturing clients. Ramón López de Haro is a name to note for supply chain management, business restructuring processes and transfer pricing controversy issues. Jose María Gómez Rosende takes the lead on transactional tax matters, with a particular focus on the private equity space, while Irene Reoyo Serrano focuses on international taxation. Recently promoted partner Jorge Martín Girola Mariño, who is particularly noted for his tax governance expertise, has played a key role in the tax structuring of M&A transactions.

‘Very strategic partner relationship, very fluid communication, recurring meetings on situation points, opportunities for improvement and resolution of incidents. Always thinking about the client.’

‘Deloitte Abogados presents a combination of multisectoral elements that facilitate a panoramic understanding of the issues. They have the ability to understand the financial and legal sector with industrial reasonableness. They have advanced use of technology in the development of their activities that allows them to extract added value from their time.
