Puerto Rico's only stand-alone law firm tax group


Tax considerations are a significant factor in any business transaction.

The McConnell Valdés Tax Practice group is the only stand-alone tax group in Puerto Rico with over a dozen seasoned attorneys committed to helping some of the world’s leading companies minimize their tax burdens and maximize the benefits of doing business in Puerto Rico.

Our profound understanding of Puerto Rico tax laws and policy enables us to pinpoint potential tax issues even in a volatile market – so that clients can plan effectively for the future. We are well connected and maintain an active and results-driven tax lobbying group that focuses on all areas of tax and tax incentives legislation that affects our clients.

Superb strategists and problem solvers, our team of seasoned attorneys is committed to helping some of the world’s leading companies minimize their tax burdens – and maximize the benefits of doing business in Puerto Rico.  They are vastly experienced in handling complex commercial and financial transactions for both multinational corporations with Puerto Rico operations as well as for local companies.

Individual team members ranked among Chambers & Partners’ Leading Attorneys in the field are singled out as “excellent,” “knowledgeable and hands-on.” A number of our attorneys are also CPAs: this training is indispensable to our understanding of complex tax and business issues – and leads to innovative solutions and tangible cost efficiencies. Others of us gained valuable insights from prior experience working in the Puerto Rico Treasury Department.

Whether providing federal and local tax advice on the formation, operation, restructuring and disposition of business entities on the island, our team’s approach couples our understanding of client business needs with responsive, highly personalized service. Chambers & Partners Latin America praises the team’s ability to make clients feel “important,” while noting our ability to offer “impeccable” guidance on future tax-related developments.
