Christopher J. Sullivan, Esq., is the President of Rath Young Pignatelli and serves on its Management Committee. Chris’ practice focuses on multi-state taxation representing clients in forums ranging from administrative agencies and court rooms to the Legislature. Chris represents corporate clients in tax matters before the New Hampshire Department of Revenue Administration, the Massachusetts Department of Revenue, and the Vermont Department of Taxes, and advises companies on multi-state matters involving states across the country. His representation includes creating value for clients during the audit, assessment and refund process for in-state and multi-state companies as well as representing corporate clients in economic development efforts choosing to locate jobs and business in the Granite State. He has devoted substantial time to nexus, apportionment and reasonable compensation issues, combined reporting issues, and the treatment of foreign source income. While other states are only recently considering or adopting combination, New Hampshire has utilized unitary combination since 1986. He works on matters involving the New Hampshire Business Enterprise Tax, Business Profits Tax, the Real Estate Transfer Tax, Interest and Dividends Tax, the Meals and Rentals Tax and Real Property Tax. He regularly advises companies regarding voluntary disclosure agreements, particularly due to accounting reserve standards FIN 48 and increased jurisdictional aggressiveness in the multi-state arena. Chris has been consistently recognized by Best Lawyers in America and in 2019 was named Lawyer of the Year, Tax Law. Chris is a nationally-recognized speaker on state tax issues. He writes articles for State Tax Notes and regular updates for the Council on State Taxation and teaches frequently on New England Tax issues.

Chris also serves on the Board of Trustees of the NYU Institute on State and Local Taxation. Appointed by the Senate President, he served on New Hampshire’s Study Commission on Apportionment on potential business tax reform and New Hampshire’s competitive position compared to other states. Chris is an honors graduate of Harvard College and Georgetown University Law Center.
