Hire Employees

When you hire employees, several actions are required:

  • You may need a Federal Employer Identification Number (EIN). Most businesses do, but you can find out for sure at the Internal Revenue Service EIN page. When you are ready to apply for the EIN, you can do it online with the IRS EIN form PDF file. If you do not acquire an EIN, then your Social Security Number (SSN) is used instead.

  • Obtain a Missouri Withholding Number and an Unemployment Tax number. Complete the application for these numbers online or file form 2643 PDF file with the Department of Revenue and form 2699 PDF file with the Department of Labor and Industrial Relations.

    If you already have a Missouri Tax Identification (ID) Number, you can add withholding tax to your existing number by e-mailing the Department of Revenue at businesstaxregister@dor.mo.gov or by calling (573) 751-5860.

  • When you hire employees, you'll want to make appropriate arrangements for q ' Compensation Insurance. For more information contact the Missouri Division of Workers' Compensation or the Department of Insurance, Finance and Professional Registration.

  • All employers in Missouri must report each newly hired employee to the Department of Revenue within 20 calendar days of hire. "Date of hire" is defined as the date the employee reports to work or the date the employee signs the federal W-4 form, whichever is earlier.

  • Each employee must complete the following forms:

  • Beginning with your first payroll, you must:

    • Withhold state income tax and federal income tax at a percentage determined by salary and exemption information stated on the form W-4. See the Missouri Department of Revenue Missouri Employer Withholding site for questions about Missouri withholding. You can also link to the Internal Revenue Circular E, Employer's Tax Guide PDF file for information on federal withholding.
    • Withhold 6.2% of the employee's salary for Social Security taxes.
    • Withhold 1.45% of the employee's salary for Medicare taxes.
    • Pay the Social Security and Medicare taxes to an approved banking institution on the 15th of the month.
    • File required payroll reports with the Department of Revenue PDF file and the Department of Labor and Industrial Relations on a quarterly and annual basis; and issue W-2 reports to employees at the end of the year.
    • For more information about payroll issues, visit the IRS website. A good resource is IRS Publication #15.

  • You are required to display appropriate work posters informing employees of their rights regarding discrimination, unemployment benefits, worker compensation, Equal Employment, Federal Minimum Wage, Family Medical Leave Act (FMLA), Occupational Safety and Health Administration (OSHA), and Polygraph Protection Act. These posters can be downloaded from Required Posters.
