The Federal Tax ID number field is at Enterprise setup instead of Employer setup. The Federal Tax ID number is often used for reporting by employer, so it would be nice to have that handy. Not everyone has payroll, so it needs to be stored on the HR side of the product. Having it at Enterprise setup doesn't do any good for clients who actually have multiple companies in their HRMS. Plus this would make it available to HR Actions forms such as tax forms for the employee where it has information on the employer.
