Tax Litigation and Appeals

We provide legal advice and defense in tax proceedings, both in administrative and contentious-administrative channels. We intervene from the early stages of proceedings with the tax authorities—requests for information, verifications, and inspections—to the challenge of decisions through appeals, economic-administrative claims, and judicial proceedings before the courts.

We prepare statements of allegations, administrative appeals, claims before the Economic-Administrative Courts (TEAR and TEAC), and contentious-administrative lawsuits before the competent jurisdiction. Our approach combines technical and regulatory analysis with procedural strategy, always seeking the most effective solution to defend the taxpayer’s interests.
