State Tax for Missouri Residents

 

Missouri has made a change to their tax guide, which effects employees who are residing in Missouri and working in other states.  These employees should submit a MO W-4C to the Payroll Office regarding their employment with KU only.  We do not need to know about jobs with other employers.  The MO W-4C helps our office determine how to set up your state withholding tax correctly. The tax situations which this form will suffice for are as follows:

  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:
  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.

 

If your tax situation does not fit one of the above, please contact the Payroll Office for further assistance.

More information regarding the new form can be found on page 4, section 4B of the State of Missouri Employer's Tax Guide.
