Tax Law

At Estudio Legal & Finanzas México, we translate tax complexity into clear and sound decisions. We develop comprehensive tax strategies designed to achieve efficiency without compromising compliance—from preventive tax planning to sophisticated tax controversy and litigation.

Our advisory services cover corporate restructurings, due diligence, compliance, transfer pricing, regulatory filings, tax refunds, and representation before tax authorities and federal courts, including conclusive agreements and administrative proceedings. Our approach is grounded in a robust legal framework and supported by documented evidence that safeguards compliance and cash flow.

We integrate legal analysis, regulatory interpretation, structural design, and strategic defense with disciplined accounting and tax execution. This includes compliance calendars, electronic accounting and CFDI controls, Tax Mailbox monitoring (Buzón Tributario), VAT/IEPS policies, and the preparation of files for tax credits and refunds.
