Disposable pay
Disposable pay means that part of current basic pay, special pay, incentive pay, retired pay, retainer pay, or in the case of an employee not entitled to basic pay, other authorized pay remaining after deductions required by law. Deductions from pay include:
(i) Amounts owed by the individual to the United States;
(ii) Amounts withheld for Federal employment taxes;
(iii) Amounts properly withheld for Federal, state, or local income tax purposes, if the withholding of the amount is authorized or required by law and if amounts withheld are not greater than would be the case if the individual claimed all dependents to which he or she were entitled. The withholding of additional amounts under 26 U.S.C. 3402(i) may be permitted only when the individual presents evidence of tax obligation that supports the additional withholding;
(iv) Amounts deducted as health insurance premiums, including, but not limited to, amounts deducted from civil service annuities for Medicare where such deductions are requested by the Health Care Financing Administration;
(v) Amounts deducted as normal retirement contributions, not including amounts deducted for supplementary coverage. Amounts withheld as Survivor Benefit Plan or Retired Serviceman's Family Protection Plan payments are considered to be normal retirement contributions. Amounts voluntarily contributed toward additional civil service annuity benefits are considered to be supplementary;
(vi) Amounts deducted as normal life insurance premiums from salary or other remuneration for employment, not including amounts deducted for supplementary coverage. Both Servicemembers' Group Life Insurance and “Basic Life” Federal Employees' Group Life Insurance premiums are considered to be normal life insurance premiums; all optional Federal Employees' Group Life Insurance premiums and life insurance premiums paid for by allotment, such as National Service Life Insurance, are considered to be supplementary;
(vii) Amounts withheld from benefits payable under title II of the Social Security Act where the withholding is required by law;
(viii) Amounts mandatorily withheld for the U.S. Soldiers' and Airmen's Home; and
(ix) Fines and forfeitures ordered by a court-martial or by a commanding officer.
