FAQ: How do I complete the Taxes screen in the Employee File using the updated MO W4 for Missouri state income tax?

With the recent changes to the withholding tax formula by the Missouri Department of Revenue, the Missouri W4 form was updated and no longer includes allowances.

When completing the Taxes screen in the Employee File in Payroll for Missouri state income tax, enter the appropriate letter for the table indicated in Line 1 on the Missouri W4 to use for the employee in the Tax Table field; enter H for Head of Household, M for Married Spouse Works, O for Married Filing Separate, S for Single, or X for Married Spouse Does Not Work.  If Line 2 is completed on the Missouri W4, complete the Additional Taxes section on the Taxes screen accordingly, by specifying the appropriate type (Fixed or Percent) to withhold for the additional taxes in the Rate Type field, selecting the Regular Pay Period Only field if applicable, and then entering the amount to withhold in the appropriate pay period field in the Additional Tax Amounts List (i.e. Every Pay Period field or Week 1 field, etc.).  If Line 3 is completed on the Missouri W4, select the Exempt field on the Taxes screen and then enter the specified amount to withhold in the Additional Taxes section.  If Line 4 is completed on the Missouri W4, select the Exempt field.

Note The Allowances field on the Taxes screen is not used with calculating Missouri state income tax for payroll batches in 2019 and forward.  If the Allowances field was previously completed for an employee, leave the number as previously entered (no need to change or delete it).  If setting up Missouri income tax for a new employee, leave the Allowances field blank.
