  • Personal exemptions for self and spouse not claimed on other Form W-4.
  • Additional exemptions for age and blindness.

Automatically Calculated Variables

DPS automatically computes the Allowance based on the exemptions claimed by the employee.

Allowance

The Allowance is based on the number of exemptions entered in the first Exemptions field. It is determined by multiplying the number of exemptions by $1900.

How DPS Calculates Tax

To calculate an employee's Montana 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 Allowance and any 401(k) and 125/Cafeteria plan contributions from the employee's annualized gross wages to determine 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.
  5. Rounds the withheld amount to the nearest whole dollar.
