Withholding Formula (Effective Pay Period 06, 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 by 26 to obtain the annual wages.
  5. Determine the dependent allowance by applying the following guideline and subtract this amount from the annual wages to compute the taxable income:

    Dependent Allowance = $1,775 x Number of Dependents

  6. Apply the taxable income computed in step 5 to the table below to determine the District of Columbia tax withholding.
