  • The Walk-In Center was re-designed in 2015 to include six taxpayer workstations to provide taxpayers the opportunity to self-serve who may not have access to a computer to file and pay their Ohio taxes electronically. Each workstation is equipped with a computer, printer and telephone to facilitate this self-service approach. If a taxpayer needs assistance to complete their tax filing transactions or have their questions answered, the taxpayer can call and speak to one of our agents.
