Gov. Mike DeWine has signed Ohio’s tax conformity fix, preserving the state’s alignment with federal tax law after lawmakers restored an emergency clause following pressure from an OMA-led employer coalition. OMA and allied groups warned that even temporary nonconformity would create unnecessary compliance costs and confusion during filing season. The final action gives employers needed certainty and keeps Ohio aligned with recent federal tax changes.
“Predictability in the tax code matters, and this fix gives employers the confidence they need to plan, comply and compete,” said Jacob Sargent, director of public policy services for the Ohio Manufacturers’ Association. 3/9/2026
