Missouri Residents


Employees who reside in Missouri but work in another state should submit a MO W-4C to the Payroll Office regarding their KU employment. The MO W-4C helps our office determine how to set up your state income tax correctly for the following situations:

  1. Employees working 100% in the state of Kansas:
    • Fill out number 1 in the box listing Kansas as the state you are performing 100% of your services
  2. Employees working 100% in the state of Missouri:
    • Fill out number 2 in the box listing 100% of your services are performed in Missouri.
    • Submit a regular MO W-4 Form.
    • Submit an Out of State Employee Form.
  3. Employees working a percentage in Missouri and a percentage in Kansas:
    • Fill out number 2 listing the percentage of time you work in Missouri.
    • Submit a regular MO W-4 form.
    • Submit an Out of State Employee Form.
    • Submit a K-4 if you haven't already or wish to update your Kansas withholding status.
  4. Employees working a percentage in Missouri and a percentage in another state:
    • Fill out number 2 listing the percentage of time you work in Missouri.
    • Submit a regular MO W-4 form.
    • Submit an Out of State Employee Form.
    • Submit the state withholding tax allowance certificate for your state. These forms can usually be found on your state's Department of Revenue website.

Failure to submit a MO W-4C may result in taxes being withheld from both Kansas and Missouri. If a MO W-4, K-4, or other state withholding certificate is not received, we will set up the tax at the default rate of single with 0 allowances.
