Biography

Mrs. Carballo focuses her practice on complex corporate tax matters, including startup operations, inbound and outbound corporate reorganizations, acquisitions, financings, exit strategies, legislative affairs, tax incentives and exemptions, and competent authority proceedings between the Puerto Rico Treasury Department and the Internal Revenue Service.

She is ranked as one of Puerto Rico’s Leading Attorneys in the Tax field by both Chambers & Partners and by Legal 500. She is also ranked in the Tax field of The Best Lawyers in Puerto Rico guide.

A substantial part of her practice is devoted to tax minimization strategies through Puerto Rico's various tax incentive programs under Act 60-2019 including export services, resident individual investors, industrial/manufacturing, and agriculture tax exemptions, as well as municipal incentives.

Many of her clients are global manufacturing companies in the pharmaceutical, medical devices and electronics sectors, as well as major retail companies, e-commerce companies, companies engaged in blockchain and cryptocurrency transactions, export service companies, and high net worth individuals.

She has extensive practical experience handling government tax and tax incentives compliance audits, as well as negotiating closing agreements and requests for rulings on various tax matters with the Puerto Rico Treasury Department.

Together with other members of the legal and accounting profession, she commented on and proposed changes to the bills which eventually became the Puerto Rico Tax Reform Act of 1987, the Puerto Rico Tax Reform Act of 2015, and the Excise Tax Act of the Commonwealth of Puerto Rico of 1987. Mrs. Carballo has spearheaded various amendments to Puerto Rico’s Internal Revenue Code, the industrial tax incentives acts of 1998 and 2008, as well as the Puerto Rico Incentives Code of 2019.

She is the author of various tax articles, including "Economic Incentives for the Development of Puerto Rico Act: The Last Frontier in Tax Incentives Legislation," which was published in the June 2009 edition of the Journal of Multi State Taxation and Incentives, and of "Puerto Rico's Subchapter N Eliminates Double Taxation," and "Puerto Rico Offers Tax Exemption for Services to Foreign Markets," which were published in the Journal of International Taxation.

She also has been a lecturer in various corporate tax and tax incentives seminars sponsored by the Puerto Rico Manufacturers Association, the Solar + Energy Storage Association of Puerto Rico, and other private organizations.

Mrs. Carballo is a member of the Columbia University Alumni Association of Puerto Rico, as well as a member and past President of the Princeton University Alumni Association of Puerto Rico. She served as Chairperson of Princeton University’s Schools Committee in Puerto Rico, and as a member of Princeton University’s National Schools Committee.

She also has served as member of the Board of Directors of various manufacturing corporations as well as not for profit organizations in Puerto Rico including Adopta Ahora Inc. where she currently serves as Chair.
