W-4 is the Federal Income Tax Withholding form. When completing this form, the employee's name and social security number should be identical to the number shown on the employee's Social Security Card. The Earnings Statement (pay stub) will reflect the current W-4 status. Please see W-4 form instructions for further information. A few helpful tools are located on the IRS Web site, a IRS Withholding Calculator and How Do I Adjust My Tax Withholding?
I-9 is the Department of Homeland Security Employment Verification form. A new employee should complete Section 1 (through "Employee Signature") only.

The most common forms to be used as verification for the I-9 form are the State-issued Driver's License, the original Social Security card, or a Certified copy of the Birth Certificate (must include an official seal). Complete instructions will be found on Page 1 and Page 3 of the I-9 form information.
