Withholding Formula (Effective Pay Period 25, 2016)

  1. Subtract the biweekly Thrift Savings Plan contribution from the gross biweekly wages.
  2. Subtract the nontaxable biweekly Federal Health Benefits Plan payment(s) (includes dental and vision insurance program, and flexible spending account − health care and dependent care deductions) from the amount computed in Step 1.
  3. Add the taxable biweekly fringe benefits (taxable life insurance, etc.) to the amount computed in step 2 to obtain the adjusted gross biweekly wages.
  4. Multiply the adjusted gross biweekly wages times 26 to obtain the annual wages.
  5. Determine the exemption allowance by applying the following guideline, and subtract this amount from the result of step 4:

    Exemption Allowance = $1,000 x Number of Exemptions1
    1 Number of exemptions claimed for self, spouse, over age 65, blindness, and dependents.
  6. Determine the additional allowance by applying the following guideline, and subtract this amount from step 5 to compute the taxable income:

    Additional Allowance = $1,500 x Number of Additional Exemptions2
    2 Number of exemptions claimed for certain qualifying dependents.
  7. Multiply the taxable income computed in step 6 by 3.23 percent to obtain the annual Indiana tax withholding.
  8. Divide the annual Indiana tax withholding calculated in step 7 by 26 to obtain the biweekly Indiana tax withholding.
