When hiring employees, have them fill out Form I-9 and Form W-4. If your employees qualify for advance payments of the earned income credit, they also must give you a Form W-5.
Form I-9. You must verify that each new employee is legally eligible to work in the United States. Both you and the employee must complete the Immigration and Naturalization Service (INS) Form I-9, Employment Eligibility Verification. You can get the form from INS offices or from the INS web site at www.ins.usdoj.gov. Call the INS at 1-800-375-5283 for more information about your responsibilities.
Form W-4. Each employee must fill out Form W-4, Employee's Withholding Allowance Certificate. You will use the filing status and withholding allowances shown on this form to figure the amount of income tax to withhold from your employee's wages.
Form W-5. An eligible employee who has a qualifying child is entitled to receive advance earned income credit (EIC) payments with his or her pay during the year. To get these payments, the employee must give you a properly completed Form W-5, Earned Income Credit Advance Payment Certificate. You are required to make advance EIC payments to employees who give you a completed and signed Form W-5. For more information, see Publication 15.
After the calendar year is over, you must furnish copies of Form W-2, Wage and Tax Statement, to each employee to whom you paid wages during the year. You must also send copies to the Social Security Administration. See Information Returns, later, for more information on Form W-2.
