White & Case S.C.

White & Case S.C.‘s tax practice is adept in both non-contentious and contentious matters. The team is skilled in cross-border tax structuring and the fiscal aspects of large-scale corporate transactions, often collaborating with the firm’s global network of offices. Equally, the group has expertise in dispute resolution, settling tax disputes in and out of court. Praised for his ’combination of knowledge and experience in corporate and tax law’, Carlos Martínez co-leads the team; he advises on transactional tax matters, international taxation and transfer pricing, and is also active in tax litigation and administrative appeals against tax assessment. Fellow co-head Elizabeth González Gasca excels in mandates related to income tax and international tax treaties. The team benefits from robust associate expertise, with notable names including Patricia López Padilla and Yazmin Trejo Olvera, both specialising in tax litigation. Since publication, the practice group has been further strengthened with the hire of Alejandro Santoyo, formerly of Ritch, Mueller y Nicolau, S.C., with effect from January 2026.
