How DPS Calculates Tax

To calculate an employee's Missouri State tax, DPS does the following:

1. Multiplies the employee's gross pay per pay period by the number of pay periods in a year to determine annualized gross wages.
2. Subtracts the employee's standard deduction, allowance, federal income tax withholdings, and any 401(k) and 125/Cafeteria plan contributions from the employee's annualized gross wages to determine the taxable income.
3. Calculates the net income tax by applying Tax Calculation Method 1 to the taxable income.
4. Divides the net income tax by the number of pay periods in a year to determine the amount to be withheld for the pay period. DPS then rounds the withheld amount to the nearest dollar.
