Biography
Guillermo has more than 30 years of experience as a lawyer, specializing in foreign trade and tax, providing services to large private companies across multiple industry sectors.
He is well known for his work in tax and trade litigation and also advises companies on procedures involving all stages of field audits conducted by the Tax Authorities, including administrative and constitutional proceedings.
He served for almost eight years at the Tax Administration Service (SAT) as Director of the Central Administration of Foreign Trade Audit, where he participated in multiple origin verification procedures under the NAFTA Agreement. He now successfully advises foreign companies from various sectors whose products have been subject to review, as well as the Mexican companies that import those goods.
Before and after his tenure at the SAT, he collaborated with prestigious law firms such as Baker&McKenzie and BDO. Today, Guillermo leads the International Trade and Customs practice.
FisherBroyles is an international law firm practicing in a number of jurisdictions both in the United States and overseas through affiliated legal entities and branch offices of those entities. Legal services in Mexico are provided through Bravo Gutierrez & Münch, S.C., a member of FisherBroyles (the “Contracting Member”), with offices located in Mexico City, at Parque Lincoln, 5th Floor, Aristoteles 77, Polanco, Mexico City, Ciudad de Mexico 11560 and in Monterrey, at Blvd. Antonio L. Rodriguez 3000-5to piso Interior, 501 Torre Albia, Col. Santa Maria 64650 Monterrey, N.L.
The FisherBroyles Members engage in coordinated international legal practice and may share certain support services but are separate legal entities, each of which is solely responsible for its own work and is not responsible for the work of any other FisherBroyles Member. Each FisherBroyles Member is subject to the laws and regulations of the particular jurisdiction or jurisdictions in which it operates. Full details of the legal and regulatory status of each FisherBroyles Member are available on the FisherBroyles website.
The use of the name FisherBroyles is for description purposes only and does not imply that the Member Firms are in a partnership or are part of an LLP. The use of the word “partner” on any Member Firm’s website or in any other Member Firm materials refers to a partner or member of a FisherBroyles Member or an employee or consultant with equivalent standing and qualifications. You agree that your relationship is with the Contracting Member and not with another FisherBroyles Member unless otherwise confirmed in writing to you. You also agree that your relationship is not with any individual who is a member, employee, or consultant (including anyone we call a partner) of the Contracting Firm Member, who will therefore assume, to the extent permitted by law, no personal liability to you. Absent the explicit agreement and consent of both entities involved, no FisherBroyles Member is responsible for the acts or omissions of, nor has any authority to obligate or otherwise bind, any other FisherBroyles Member.
