Withholding Formula (Residents) (Effective Pay Period 04, 2024)

  1. Subtract the nontaxable biweekly Thrift Savings Plan (TSP) 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 (e.g., taxable life insurance) to the amount computed in step 2 to obtain the adjusted gross biweekly wages.
  4. Multiply the adjusted gross biweekly wages by the number of pay dates in the tax year to obtain the gross annual wages.
  5. Determine the standard deduction by applying the following guideline and subtract this amount from the gross annual wages:

    Single - S or Head of Household - H

    Married - N (Filing Separate or Joint Return - Both Spouses Working)

    Married - M (Filing Joint Return - One Spouse Working)




  6. Determine the dependent allowance and any additional allowances by applying the following guideline and subtract this amount from the result of step 5:

    Dependent Allowance = $3,000 x Number of Dependents and additional allowances.

  7. Multiply the result of step 6 by 5.49 percent to obtain the amount of annual Georgia tax withholding.
  8. Divide the annual Georgia tax withholding by the number of pay dates in the tax year to obtain the biweekly Georgia tax withholding.
