Business Registration

All business taxpayers must be registered with the Ohio Department of Taxation. The department offers two methods to accomplish this - through the Ohio Business Gateway or by telephone. Each option is explained below.

  • Ohio Business Gateway  - The Gateway is the most comprehensive business online service available in Ohio. Taxpayers can electronically register for the commercial activity tax (CAT), sales tax, employer withholding, unemployment compensation, workers' compensation, and municipal income taxes for nearly 500 cities and villages. Filing and payment can also be done through the Gateway.
  • Limited registration is available from the department by telephone. Seller's Use accounts (UT-1000), Consumer's Use accounts (UT-1008), and Employer Withholding accounts (IT-1) may be registered, and School District Withholding accounts may be activated as well. Call (888) 405-4089 to use this service.
