Widely considered a leading authority on tax policy and state and local tax issues, Tony Mastin focuses his practice on advising individuals, high net worth families, tax-exempt organizations, and businesses of all sizes on planning matters involving state and local taxation (SALT), including sales and use taxes, multi-state taxation, SALT controversy work, and federal income taxation. He is a member of the Independent SALT Alliance (ISA).

Tony serves as co-leader of the firm’s Economic Development, Tax Credits and Business Incentives Group and devotes a portion of his practice to assisting developers, investors and businesses in obtaining and maximizing the use of business incentives, including tax exemptions and tax credits.

Tony’s achievements have earned him inclusion in Chambers USA Guide to America’s Leading Lawyers for Business and The Best Lawyers in America (tax law).

Tony joined McAfee & Taft in 2019 following his retirement from the Oklahoma Tax Commission after 35 years of service, including 12 years in which he served as its executive director. Over the course of his illustrious career at the OTC, he also served as an attorney in the General Counsel’s office, deputy director of the Motor Vehicle Division, deputy director of the Business Tax Division, and director of the Tax Policy and Research Division. As executive director from 2007 – 2019, he was responsible for managing the day-to-day operations of the agency, serving as its legislative liaison, and assisting in the proposal, drafting, review and analysis of tax legislation.

Tony’s approachable style, thoughtful manner, and keen understanding of complex technical business and tax issues have earned him a reputation as a consummate professional with a practical approach to problem solving.

On the national level, Tony played an active role in the Streamlined Sales Tax Project (SSTP), a nationwide effort by state and local governments and the private sector to simplify and modernize sales and use tax collection and administration. That effort led to the development and implementation of the Streamlined Sales and Use Tax Agreement. Upon initiation of the SSTP in 2000, Tony served as the Oklahoma delegate for the project’s State and Local Advisory Council (SLAC) and was a member of its steering committee, served as scribe on the original drafting committee, and was also a member of the Compliance Review and Interpretations Committee and the Issue Resolution Committee.

In 2017, The Federation of Tax Administrators honored Tony with the Harley T. Duncan Award for his sustained and significant service to state tax administrators.
