What Is an EIN and Why Is It Important?

An Employer Identification Number (EIN)—sometimes called a Federal Tax ID—is a unique nine-digit number assigned by the IRS to identify a business entity for tax purposes. Think of it as your business’s Social Security number. You’ll need an EIN to hire employees, open a business bank account, obtain local business licenses, and file federal or state taxes. In Caldwell County, Kentucky, even small family operations or home-based businesses often benefit from having an EIN, especially when dealing with local banks or vendors.
