    3. Determine the exemption allowance by applying the following guideline and subtract this amount from the result of step 2.

      4. Exemption Allowance = $1,000 x Number of Exemptions1

      1 Number of exemptions claimed for self, spouse, over age 65, blindness, and dependents.

    4. Determine the additional allowance by applying the following guideline and subtract this amount from the result of step 3 to compute the taxable income:

      5. Additional Allowance = $1,500 x Number of Additional Exemptions2

      2 Number of exemptions claimed for certain qualifying dependents.

    5. Optional: determine the adopted child dependent exemption applying the following guideline and subtract this amount from the result of step 4 to compute the taxable income:

      6. Adopted child exemption = $3,000 x Number of Adopted child exemption 2

      2 Number of exemptions claimed for certain qualifying dependents.

    6. Multiply the taxable income computed in step 4 by 3.00 percent to obtain the annual Indiana tax withholding.
