Ohio Business Gateway Registration helps Employers register for state tax accounts and manage payroll-related services through a single online portal.
This Employer Guide explains How To create an OBG account, register for withholding and unemployment taxes, set up local withholding, and grant third party access.
1. Overview of Ohio Business Gateway Registration
The Ohio Business Gateway (OBG) is the state’s online hub for business tax filings and account management.
Using OBG simplifies Employer Withholding filings, payments, and access to related state services administered by the Ohio Department of Taxation and the Ohio Department of Job and Family Services.
What Is a Federal Employer Identification Number (FEIN)?
A FEIN is issued by the Internal Revenue Service and is your business federal tax identifier.
Most Employers need a FEIN to register for Ohio withholding and unemployment accounts and to hire employees legally.
How To Create an OBG Account
Visit the Ohio Business Gateway at gateway.ohio.gov and click Create an Account to begin.
Provide an email, contact details, and a secure password, then verify your email to complete the account setup and access registration tools.
2. Registering For Employer Withholding Tax
After logging into OBG select Start a New Registration and choose Employer Withholding to begin registration.
Enter your FEIN or SSN, legal business name, address, and other requested details to complete the application.
When processing is complete OBG will issue an eight digit Ohio Employer Withholding Account Number in a confirmation letter you should keep for payroll setup.
Tips For Entering Information
Use the exact legal name and address that appears on your FEIN paperwork to avoid processing delays.
Keep copies of your confirmation letter and update Payroll Software with the eight digit account number as soon as you receive it.
3. Registering For Unemployment Insurance Tax
Unemployment Insurance (UI) registration is handled through The SOURCE, the Ohio Department of Job and Family Services online portal.
On The SOURCE choose Employers then Register For an Account and complete the employer registration to receive your Unemployment Compensation Tax Account Number and assigned tax rate.
Employer Responsibilities For UI
Once registered Employers must report wages and submit UI tax payments according to Ohio filing schedules.
Monitor your tax rate notices and respond promptly to any audits or requests from the Department of Job and Family Services.
4. Registering For Local Withholding Tax
Many Ohio municipalities levy local income taxes that require Employer withholding and reporting.
Use the Ohio Municipal Tax Finder Tool to determine local requirements based on business location and employee residency.
Major Local Agencies
Contact local tax agencies such as the Central Collection Agency (CCA) or the Regional Income Tax Agency (RITA) to register where required.
Local registration often requires separate forms and may have different filing frequencies than state withholding accounts.
5. Granting Third-Party Access
If a Payroll Provider or Accountant will file on your behalf they may request access to your OBG account.
Log in, go to the Administration tab, and approve the access request to grant the third party permission to file and pay on your behalf.
Security and Access Best Practices
Grant access only to trusted Payroll Providers and limit permissions to necessary functions.
Review third party access periodically and revoke access promptly if service relationships change.
6. Maintaining Compliance
Timely filing and payment are essential to avoid penalties and interest on Employer Withholding and UI accounts.
Set calendar reminders for filing dates, keep payroll records, and reconcile account notices from the Ohio Department of Taxation and The SOURCE.
- Set up your FEIN before starting state registrations.
- Create an OBG account to manage state withholding and other transactions.
- Register UI on The SOURCE to obtain your unemployment account number and rate.
- Use the Municipal Tax Finder to identify and register for local taxes.
- Authorize third parties through the OBG Administration tab when needed.
Common Mistakes To Avoid
Do not delay applying for your FEIN because state registrations typically require it and delays will hold up account issuance.
Do not forget To update Payroll Software with the eight digit Ohio Employer Withholding Account Number and to check local agency requirements.
