Rich is the director of Sullivan’s Tax Department. He concentrates on state and local tax (SALT) litigation and transactional planning involving corporate, personal income and sales/use tax matters. He has more than two decades of experience before the Massachusetts Appellate Tax Board, the Supreme Judicial Court, various state Departments of Revenue and the Internal Revenue Service on a range of issues, including corporate nexus, domicile, apportionment, step transaction, and unitary reporting. He has served clients across sectors including technology, financial services, retail, media, manufacturing, telecommunications, e-commerce, software and construction.
Rich has developed a strong record in representing clients in SALT controversies over the years, including a string of recent victories in landmark Massachusetts tax cases. In 2021 he argued and prevailed before the Massachusetts Supreme Judicial Court in Oracle v. Commissioner of Revenue, which affirmed the right of businesses to apportion sales tax on software used in multiple states. The Oracle decision was named a top SALT case of 2021 by Law360 and a Top Indirect Tax Dispute Worldwide for Q2 2021 by International Tax Review. In 2023, Rich notched another win before Massachusetts’ highest court in Reagan v. Commissioner of Revenue, reversing the state’s policy of assessing sellers of exempt urban redevelopment projects; the case marked an important victory for taxpayers as well as urban renewal and affordable housing.
