Registering a New Business in Kentucky

Federal Employer Identification Number (FEIN)

All businesses are encouraged to obtain a Federal Employer Identification Number (FEIN) even if not required federally. While Sole Proprietorships and Disregarded Entities without employees may not need a FEIN for federal purposes, it helps differentiate businesses with similar names and can serve as an alternative to using a personal Social Security Number.​​​​
