Automatically Calculated Variables

Deltek automatically computes the following variables.

Standard Deduction

The Standard Deduction is a variable deduction applied to all employees. The deduction is based on the employee’s gross wages and filing status.

Allowance

The Allowance is based on the number of withholding exemptions entered in the first Exemptions field. It is determined by multiplying the number of exemptions by $400.

How Deltek Calculates Tax

To calculate an employee's Wisconsin State tax, Deltek 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, and any 401(k) and 125/Cafeteria plan contributions from the employee's annualized gross wages for the pay period to determine taxable income.
3. Determines the computed tax by applying Tax Calculation Method 1 to the taxable income.
4. Divides the annual income tax by the number of pay periods in a year to determine the amount to be withheld for the pay period.
