How Vision Calculates Tax

To calculate an employee's Montana State tax, Vision 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 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. Vision then rounds the withheld amount to the nearest whole dollar.
