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.
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
