Career
Guillermo has more than twenty years of experience in tax planning, including taxation of corporate restructuring transactions, mergers, acquisitions, and general tax advice, especially for business and multinational groups with operations in Mexico where he provides advice to achieve fiscal efficiency and provide assistance in developing tax policies for ongoing operations. His experience extends to transfer pricing, including the legal analysis of the implementation of policies, documentation and elaboration of economic studies and defense files to protect companies against potential tax investigations. Guillermo has represented different industries before the Mexican Judiciary through constitutional (“amparo”) proceedings to contest the creation or amendments of tax laws that produce relevant economic negative effects, achieving tax refunds and the protection to future payments. He has also assisted multinational companies in complex cross-border tax litigation, in transfer pricing adjustments, cost-sharing arrangements, multinational restructures, and potential re-characterization of intercompany payments being able to successfully defend cases in the investigation stage or to reduce potential liabilities before contesting deficiencies before the Federal Tax Court. Guillermo is a member of the firm’s Energy Industry Group.
