Register for Employer Withholding and Unemployment Compensation

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 GatewayThe 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".

If you have registered for an employer withholding account, you do not need to register separately for school district withholding. Employers use the same account number for both employer and school district withholding.
