Santamarina + Steta Strengthens its Tax Practice with two New Partners
The new partners, together with Mariano Calderón Vega and a well-established team of tax attorneys, expand the Firm's capacity to meet the growing demand for tax advisory services in Mexico.
Mexico City, May 6, 2026. — Santamarina + Steta announces the addition of Luis Curiel Piña and Francisco Arturo Carbajal Domínguez as partners in its tax advisory and tax litigation practices. The incorporation, facilitated by Kerma Partners / AIM Legal Headhunters, brings both professionals, along with a strong team of specialized attorneys, together with Mariano Calderón Vega, the firm's partner in administrative and tax litigation, forming a group with the capabilities needed to handle both tax advisory and tax litigation and disputes at the highest level.
Luis Curiel Piña specializes in tax litigation. He has advised domestic and international companies in disputes before tax authorities, audits, refunds, and administrative appeals. With more than 25 years of experience, his approach combines preventive strategy with actionable defense. Chambers & Partners ranks him in Band 2 for Tax Controversy, and Legal 500 recognizes him as a Leading Partner. He currently serves as first vice president of ANADE and will assume the presidency in 2027.
Francisco Arturo Carbajal Domínguez, with more than 20 years of experience, specializes in tax advisory and counsels on complex transactions: mergers and acquisitions, restructurings, financing, and multi-jurisdictional investments. Chambers & Partners recognizes him as Up & Coming in non-contentious tax, and Legal 500 distinguishes him as a Next Generation Partner.
This integration reflects a clear decision: to strengthen the firm's legal services offering in the area that companies in Mexico consider their top priority. According to the 2025 Legal Services Trends Study in Mexico, conducted by Santamarina + Steta with the participation of 150 legal leaders in the country, the tax area tops the list of issues that will receive the most attention over the next 12 months and remains the most critical over a five-year horizon.
With this addition, Santamarina + Steta's reinforced tax platform joins one of the most active transactional platforms in the Mexican market — recognized for its track record in mergers and acquisitions, restructurings, and financings — forming a team of partners and associates whose profiles complement each other to provide comprehensive advisory services to all of the Firm's clients.
What this means for clients

With this addition, Santamarina + Steta strengthens its ability to structure transactions with tax implications: M&A, financings, and restructurings, integrating the tax function at the core of the legal strategy. 79 years of experience, now with greater depth on one of the market's most critical fronts.
