Back-period exposure & voluntary disclosure
Ohio participates in the Multistate Tax Commission's voluntary disclosure program, and the Department of Taxation offers its own disclosure process for sellers who come forward before being contacted.
- Lookback
- Typically 3 years under a voluntary disclosure — versus a longer exposure window if the state initiates contact
- Penalties
- Generally waived under a voluntary disclosure agreement
- Interest
- Still due on back taxes — interest relief is limited
- Unfiled returns
- No statute of limitations runs until a return is filed; early disclosure limits total exposure
