Withholding Formula (Effective Pay Period 06, 2013)

  1. Subtract the nontaxable 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 adjusted gross biweekly wages.
  3. Add the taxable biweekly fringe benefits (i.e., taxable life insurance) to 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 exemption allowance by applying the following guideline and subtract this amount from the annual wages to obtain the taxable income:

    Exemption Allowance = $1,144 x Number of Exemptions

  6. Apply the taxable income determined in step 5 to the following tables to determine the Hawaii tax withholding:
