Section 5520a of title 5 of the United States Code provides that with certain exceptions set forth in this part, pay from an agency to an employee is subject to legal process in the same manner and to the same extent as if the agency were a private person. The purpose of this part is to implement the objectives of section 5520a as they pertain to each executive agency of the United States Government, except with regard to employees of the United States Postal Service, the Postal Rate Commission, and the General Accounting Office.

In this part—(1) Agency means each agency of the executive branch of the Federal Government, excluding the United States Postal Service, the Postal Rate Commission, and the General Accounting Office; agency does not include the government of the District of Columbia or the territories and possessions of the United States. (Section 5520a(j)(1) of title 5 of the United States Code provides that separate implementing regulations shall be promulgated by the legislative branch and the judicial branch; section 5520a(k) provides that separate implementing regulations shall be promulgated with regard to members of the uniformed services; and Executive Order 12897 provides that separate implementing regulations shall be promulgated with regard to employees of the United States Postal Service. The regulations promulgated for employees of the United States Postal Service also apply to employees of the Postal Rate Commission.)

(2) Employee or employee-obligor means an individual who is employed by an agency as defined in this section, including a reemployed annuitant, an individual engaged in phased employment as defined in part 831, subpart Q, and part 848 of this chapter, and a retired member of the uniformed services who is employed by an agency. Employee does not include a retired employee, a member of the uniformed services, a retired member of the uniformed services, or an individual whose service is based on a contract, including an individual who provides personal services based on a contract with an agency.

(3) Legal process means any writ, order, summons, or other similar process in the nature of garnishment, which may include an attachment, writ of execution, court ordered wage assignment, or tax levy from a State or local government, which—

(i) Is issued by:

(A) A court of competent jurisdiction, including Indian tribal courts, within any State, territory, or possession of the United States, or the District of Columbia. As stated in § 582.101, pay is subject to legal process in the same manner and to the same extent as if the agency were a private person. There is, therefore, no requirement in this part that, for example, legal process be signed by a Judge; or.

(B) An authorized official pursuant to an order of a court of competent jurisdiction or pursuant to State or local law; or

(C) A State agency authorized to issue income withholding notices pursuant to State or local law; and

(ii) Orders an agency to withhold an amount from the pay of an employee-obligor and to make a payment of such withholding to a person, for a specifically described satisfaction of a legal debt of the employee-obligor, or recovery of attorney fees, interest, or court costs;

(4) Person may include an individual, partnership, corporation, association, joint venture, private organization or other legal entity, and includes the plural of that term; person may include any of the entities that may issue legal process as set forth in § 582.102(3)(i) (A), (B), and (C), and a State or local government as well as a foreign entity or a foreign governmental unit, but does not include the United States or an agency of the United States.

(5) In conformance with 5 U.S.C. 5520a, pay means basic pay; premium pay paid under chapter 55, subchapter V, of title 5 of the United States Code; any payment received under chapter 55, subchapters VI, VII, and VIII, of title 5 of the United States Code; severance pay and back pay under chapter 55, subchapter IX, of title 5 of the United States Code; sick pay, and any other paid leave; incentive pay; locality pay (including special pay adjustments for law enforcement officers and locality-based comparability payments); back pay awards; and any other compensation paid or payable for personal services, whether such compensation is denominated as pay, wages, salary, lump-sum leave payments, commission, bonus, award, or otherwise; but does not include amounts received under any Federal program for compensation for work injuries; awards for making suggestions, reimbursement for expenses incurred by an individual in connection with employment, or allowances in lieu of thereof as determined by the employing agency.

In determining the amount of pay subject to garnishment under this part, there shall be excluded amounts which:

(a) Are owed by the employee-obligor to the United States;

(b) Are required by law to be deducted from the employee-obligor's pay, including, but not limited to amounts deducted in compliance with the Federal Insurance and Contributions Act (FICA), including amounts deducted for Medicare and for Old Age, Survivor, and Disability Insurance (OASDI);

(c) Are properly withheld for Federal, State, or local income tax purposes, if the withholding of the amounts is authorized or required by law and if amounts withheld are not greater than would be the case if the employee-obligor claimed all dependents to which the employee-obligor were entitled. The withholding of additional amounts pursuant to section 3402(i) of title 26 of the United States Code may be permitted only when the employee-obligor presents evidence of a tax obligation which supports the additional withholding;

(d) Are deducted as health insurance premiums;

(e) Are deducted as normal retirement contributions, not including amounts deducted for supplementary coverage. For purposes of this section, all amounts contributed under sections 8351 and 8432(a) of title 5 of the United States Code to the Thrift Savings Fund are deemed to be normal retirement contributions. Except as provided in this paragraph, amounts voluntarily contributed toward additional retirement benefits are considered to be supplementary;

(f) Are deducted as normal life insurance premiums from salary or other remuneration for employment, not including amounts deducted for supplementary coverage. Federal Employees' Group Life Insurance premiums for “Basic Life” coverage are considered to be normal life insurance premiums; all optional Federal Employees' Group Life Insurance premiums and any life insurance premiums paid for by allotment are considered to be supplementary.

(g) Amounts withheld in compliance with legal process based on child support and/or alimony indebtedness are not exclusions.
