Gustavo Ortiz M.
With over 7 years of experience in tax litigation and dispute resolution, Gustavo has specialized in the design and implementation of defense strategies to challenge the legality of administrative acts and the constitutionality of tax provisions, both at the federal and local levels.
He has extensive experience in handling complex cases related to the validation of business models and the accreditation of the materiality of operations, through the filing of appeals and lawsuits in traditional and digital channels.
Furthermore, I specialize in handling tax audits, focusing on preventing tax assessments or, if necessary, structuring a litigation strategy with a high probability of success. I have experience negotiating and formalizing conclusive agreements with the Taxpayer Defense Attorney's Office, which allows taxpayers to avoid or significantly reduce their tax liabilities before a tax assessment is issued.
