The tax practice at White & Case S.C. focuses on the tax structuring of M&A, corporate finance transactions and private equity investments, including advising on the formation, investment and divestment of private equity funds. The team also handles contentious matters, with experience in disputes involving the interpretation of international tax treaties and transfer pricing issues. The practice is directed by January 2026 arrival Alejandro Santoyo, formerly of Ritch, Mueller y Nicolau, S.C., who draws on significant experience in tax consulting, as well as in advising HNWIs on wealth planning mandates. Additional key contacts include Elizabeth González Gasca, who regularly represents clients in audits, administrative proceedings and litigation before Mexican tax authorities and courts. Experienced associate Yazmin Trejo Olvera (whose career includes a five-year stint at Mexico’s tax authority) support on both advisory and contentious mandates. Former practice co-head Carlos Martínez left the firm in August 2026, as did associate Patricia López Padilla the following month.
