What Is an EIN and Why Is It Important?

An EIN, or Employer Identification Number, is a federal tax ID issued by the IRS. Think of it as a Social Security Number for your business. It’s used for everything from opening a business bank account to filing federal and state taxes, hiring employees, and applying for local business licenses. In Franklin County, having an EIN is often required for registering with local agencies, collecting sales tax, and staying compliant with Ohio business laws.

Doing Business in Franklin County, Ohio: Local Considerations

Franklin County, home to Columbus—the state capital—boasts a vibrant business environment. From bustling Short North boutiques to tech startups in Dublin, the region offers a supportive ecosystem for entrepreneurs. Local agencies such as the Columbus Department of Development and Franklin County Economic Development and Planning can help you navigate licenses and permits, but nearly all require your business to have an EIN first.

Additionally, many local banks and credit unions in Franklin County will ask for your EIN before opening a business account. If you plan to hire Ohio-based employees, you’ll also need your EIN to register with the Ohio Department of Job and Family Services for payroll and unemployment insurance.
