Automatically Calculated Variables

DPS automatically computes the Allowance, which is used in determining net income tax.

Allowance

The Allowance is based on the number of exemptions in the first Exemptions field. It is determined by multiplying the number of exemptions by $2,960.

Supplemental

Supplemental (bonus run) wages are calculated at a flat rate of 6.92%.

How DPS Calculates Tax

To calculate an employee's Idaho 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 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. DPS then rounds the withheld amount to the nearest dollar.
