Frequently Asked Questions

When should a business hire a Tax Lawyer?
A company should seek legal advice as soon as it receives a notice from the SAT, faces a tax audit, plans a significant corporate transaction, or wishes to strengthen its tax compliance program. Early legal intervention often prevents costly disputes.

Can a SAT tax assessment or penalty be challenged?
Yes. Many tax assessments and administrative penalties may be challenged through administrative appeals, nullity actions before the Federal Administrative Court, or constitutional proceedings, depending on the circumstances of each case.

What is a SAT invitation letter?
A SAT invitation letter is a communication issued by the Mexican Tax Administration Service requesting that a taxpayer clarify, correct, or regularize a specific tax matter. Although it is not a formal audit, it should be addressed promptly with appropriate legal guidance.

What is Article 69-B of the Mexican Federal Tax Code?
Article 69-B establishes the legal framework under which the SAT may presume that certain taxpayers have issued invoices covering nonexistent transactions. Businesses involved in these proceedings require specialized legal representation to protect their rights and commercial operations.

Do you represent international companies doing business in Mexico?
Yes. We regularly advise foreign investors, multinational corporations, and international businesses regarding Mexican tax compliance, corporate taxation, tax controversies, and administrative litigation.
