What Is an EIN and Why Is It Essential?

An Employer Identification Number (EIN), sometimes called a Federal Tax Identification Number, is a unique nine-digit number assigned by the IRS. Think of it as a Social Security number for your business. You’ll need an EIN to open a business bank account, hire employees, file federal and state taxes, and apply for local business permits in Polk County. Even if you’re a sole proprietor in Lakeland, Winter Haven, or Bartow, an EIN can help separate your personal and business finances.
