USA State Payroll Rates + Resources: State of Ohio: Obtaining a TIN + Unemployment Insurance

The purpose of this documentation is to outline the processes and requirements associated with becoming a new employer in the state of Ohio. Specifically, we will be covering how to obtain a Tax Identification Number and Register for Unemployment Insurance. 

All business taxpayers must be registered with the Ohio Department of Taxation. The department offers the following three methods to accomplish this:

Ohio Business Gateway: The Gateway is the most comprehensive business online service available in Ohio. Taxpayers can electronically register for employer withholding and unemployment compensation, workers' compensation, and municipal income taxes for nearly 500 cities and villages. Filing and payment can also be done through the Gateway. You will be asked to designate a contact person and to list the name and job title of the person who will be reporting the tax information. Once registered, you can start filing your returns immediately.

Once on the website, click on "Never used the Gateway? - Create an Account".

Telephone: Limited registration is available from the department by telephone. Employer Withholding accounts (IT-1) may be registered by calling (888) 405-4089.
