Withholding Formula (Effective Pay Period 12, 2018)

  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. Subtract the standard deduction of $2,530 from the result of step 4 to compute the taxable income.
  6. Apply the flat tax rate of 5 percent to the annual taxable wages in step 5 to determine the annual tax amount.
  7. Divide the annual Kentucky tax withholding calculated in step 6 by the number of pay dates in the tax year to obtain the biweekly Kentucky tax withholding.
