Withholding Tax and MO W-4

The Department of Revenue strongly encourages all employees to review their W-4, making any necessary changes based on their specific filing situation. Employees do not have the option of increasing or decreasing the amount withheld from their paychecks by claiming allowances that are not consistent with their specific filing status. If the employee needs additional amounts withheld, they should add the additional amount on line 2 of the W-4.

The withholding tax tables, withholding formula, MO W-4, Missouri Employer’s Tax Guide (Form 4282), and withholding tax calculator can be found here.

Employees with multiple employers may refer to our “Completing a New MO W-4 If You Have More Than One Employer” example to make changes to their Missouri W-4s.

The Department of Revenue has a number of tools available to help our customers when it comes time to pay their Missouri taxes, if they need assistance. Access online services information. for more information.

(Section 143.191, RSMo) Withholding is the tax that an employer deducts and withholds from employees’ wages every pay period. The withholding is based on the employee’s wages during that pay period. When the employee calculates his income taxes for the year, the amount of taxes withheld helps determine whether a refund is issued to the taxpayer (more was withheld than necessary) or whether the taxpayer owes more in tax (less tax was withheld than necessary).

The information and links below are helpful to businesses that must withhold taxes for their employees.
