Chévez, Ruíz, Zamarripa y Cía has a large and reputable tax team that is active in all practice areas, serving clients from the industrial, commercial and financial sectors particularly. The tax team, comprising 37 partners and 256 fee earners, is divided into subgroups: Manuel Sainz Orantes leads the tax litigation group; Iván Moguel Kuri is in charge of tax consulting; and Oscar Campero San Vicente is head of transfer pricing. The firm lost one partner in November 2011 when Daniel Amezquita left to join Galicia Abogados. The firm is widely respected in the marketplace. One competitor singled out Enrique Ramírez Figueroa as the best tax litigator in the country: "He not only knows the procedures and the way litigation works, but he is actually a very, very good lawyer who knows taxes." Ricardo Rendón, who specialises in M&A, cross-border structuring and transfer pricing, is recognised by peers for his expertise in corporate tax, while Francisco Moguel Gloria has earned the respect of competitors for his work in indirect tax.

As tax adviser to Pemex, the country's only state-owned oil company, PwC is a leader in tax-related issues in the energy sector. It has drafted opinion letters for Pemex about the tax implications of opening up the country's oil sector and is advising on the tax aspects of three incentive-based contract deals the government awarded in October and November 2011. These contracts effectively open up the oil sector to foreign companies, which will be paid in cash, not oil, since the constitution does not allow any company, aside from Pemex, to exploit the country's oil reserves. Apart from the energy sector, PwC's tax practice is also particularly strong in the auto industry, consumer goods and media. During the past year, the group was involved in the largest M&A transaction in Mexico's history. David Cuellar, international tax services partner and infrastructure and energy, oil and gas leader, was the lead Mexican tax partner for Anheuser Busch InBev in its $20.1billion acquisition of Mexico's Grupo Modelo, makers of Corona Beer. Ivan Jaso leads PwC 's indirect tax practice. Karina Perez, a former adviser at Servicio de Administracion Tributaria (SAT), Mexico's tax authority, heads the tax dispute practice, which acquired a new partner with the promotion of Fernando Lorenzo in July 2012. Mauricio Hurtado, who leads the transfer pricing practice, is highly regarded by peers. "I would not recommend anyone else for transfer pricing issues," one competitor said. Hurtado's group lost a partner when Jaime Heredia Montejano left to join Ernst & Young in February 2012.

Basham, Ringe y Correa is a full-service law firm with a tax practice that provides tax consulting, tax planning and tax litigation services. The practice, headed by Luis Ortiz Hidalgo, also advises on transfer pricing but does not carry out transfer pricing studies. Clients include companies from the pharmaceutical, foods, construction, mining, media, and financial services sectors. The firm represented a nutritional supplements company, which the tax authorities claimed owed $150 million in VAT for an 18-month period. The tax authority asserted that, the company's products are subject to a 16% sales tax because they do not fall under the tax-exempt "products intended for nourishment" category. The SAT is trying to narrowly define this category to include only products consumed in their natural state. Ruling on this case, which is at the administrative appeals court level, is pending.
