  • State withholding Form
    • Not required in states that do not have a personal income tax.
    • Check with your state.
1. Form W-4, Employee's Withholding Allowance Certificate:
  • Each new hire must complete a Form W-4.
  • Withhold federal income tax based on each employee's Form W-4.
  • A new W-4 must be completed whenever an employee wants to change exemption allowances.
  • Keep the original in your files.
2. Form I-9, Employment Eligibility Verification
  • This must be completed by both the employer and employee.
  • This is a U.S. Citizenship and Immigration Services form (USCIS).
  • This form must be completed by the employee and employer.
  • As an employer you are responsible for verifying that each new employee is legally eligible to work in the United States.
