Statewide
Ohio's data center sales and use tax exemption, approved project by project by the Ohio Tax Credit Authority, can waive up to all of the 5.75% state sales tax on qualifying equipment for facilities of $100 million or more for up to 15 years; the state reported it cost about $555 million in 2024 and about $1.57 billion in 2025, far above its own forecasts. (Cleveland 19 (Associated Press, from Signal Ohio), May 21, 2026; Signal Ohio, June 11, 2026) Lawmakers repealed the exemption in the 2025-2027 budget, House Bill 96, but Gov. Mike DeWine vetoed that provision in 2025; House leaders later said they lacked the 60 votes to override. (WYSU (Statehouse News Bureau), Aug. 8, 2025; Signal Ohio, June 11, 2026) On May 27, 2026, DeWine directed the Tax Credit Authority to stop taking new data center exemption requests after its June 1 meeting while the General Assembly's Joint Data Center Committee studies the industry; existing exemptions are unaffected. (Office of Ohio Gov. Mike DeWine, May 27, 2026; ENR, May 29, 2026) A legislative package from the joint committee that would have shrunk future data center tax breaks was pulled before a floor vote on June 10, 2026, the last scheduled session before the November election; no change was adopted. (Signal Ohio, June 11, 2026) The Public Utilities Commission of Ohio approved AEP Ohio's data center tariff on July 9, 2025 (Case No. 24-0508): new data centers above 25 MW must pay for at least 85% of their subscribed monthly capacity for up to 12 years, including a four-year ramp, with exit fees and financial-assurance rules, and the order set a path to end AEP's March 2023 moratorium on new central Ohio data center service agreements. (POWER Magazine, July 10, 2025; Renewable Energy World, July 10, 2025) A Brown County group began circulating a proposed state constitutional amendment in March 2026 that would bar construction of data centers larger than 25 MW; it had not been certified as of the source.
