The Bottom Line

Ohio's dual deadline system - March 31 for most counties, May 31 for others - requires knowing your specific county's rules. Combined with the triennial update cycle and continuous enrollment option, Ohio's system is complex but navigable.

Whether fighting Cleveland's urban decay valuations or Columbus's growth distortions, success requires understanding both county deadlines and local market realities. The Board of Revision process, while formal, offers real opportunities for relief.

In the Buckeye State, knowing your county's deadline and triennial status is half the battle.

Critical Note: Ohio counties can choose between March 31 or May 31 deadlines for property tax complaints. Most use March 31, but major counties like Franklin (Columbus) extend to May 31. Additionally, triennial update cycles create different evidence rules depending on your county's schedule. Verify both your deadline and update status before proceeding.
