Things to consider when hiring new employees:
Eligibility for employment. You must verify that each new employee is legally eligible to work in the United States. This will include completing the U.S. Citizenship and Immegration Services (USCIS) Form I-9, Employment Eligibility Verification. You can get the form from USCIS offices or by calling 1-800-870-3676 or visit the USCIS Web Site at www.uscis.gov.
New hire reporting. You are required to report any new employee to a designated state new hire registry. Many states accept a copy of Form W-4 with employer informaton added.
Income tax witholding. Ask each new employee to complete the 2007 Form W-4
Name and social security number. Record each new employee's name and number from his or her social security card. Any employee without a social security card should apply for one.
