Other notable areas are tax advisory work, legal opinions and M&A transactions, as well as anti-avoidance rules, international restructuring and double taxation treaties. Recent mandates include assisting Chilean healthcare conglomerate Isapre Cruz Blanca with challenging a tax assessment issued by the Chilean Internal Revenue Service (IRS). Co-leading the team, current President of the Chilean Institute of Tax Law, Mario Silva, advises corporate, family office and private wealth clients on tax planning, corporate restructuring, and personal and corporate taxation; finance, energy and natural resources sector specialist Guillermo Infante assists with M&A-related tax issues; and former Chilean IRS official, Arturo Selman, heads up the firm’s tax disputes department. In the associate ranks, the workload of principal Ariel Castillo covers tax structuring, and cross-border and domestic reorganisations; ruling requests before Chile’s tax authorities; and assisting private clients with wealth organisation matters. Since publication, Castillo has been raised to the partnership - effective as of January 2026.
