5 USC 8463 - Rate of benefits

Each annuity payable from the Fund is stated as an annual amount, one-twelfth of which, rounded to the next lower dollar, constitutes the monthly rate payable on the first business day of the first month beginning after the month for which it has accrued.

(a) 
(1) Except as otherwise provided in this chapter
(A) an annuity payable from the Fund commences on the first day of the month after

(2) Notwithstanding paragraph (1)(A)(i), an annuity payable from the Fund commences on the day after separation from the service in the case of an employee or Member
(A) who retires under section 8412; and
(B) whose separation occurs upon the expiration of a term (or other period) for which the individual was appointed or elected.
(b) Except as otherwise provided in this chapter, the annuity of an annuitant under subchapter II or V of this chapter terminates on the date death or other terminating event occurs.

5 USC 8464a - Relationship between annuity and workers compensation

(a) 
(1) An individual is not entitled to receive
(A) an annuity under subchapter II or V, and
(B) compensation for injury to, or disability of, such individual under subchapter I of chapter 81, other than compensation payable under section 8107,

covering the same period of time.

(2) An individual is not entitled to receive an annuity under subchapter IV and a concurrent benefit under subchapter I of chapter 81 on account of the death of the same person.
(3) Paragraphs (1) and (2) do not bar the right of a claimant to the greater benefit conferred by either this chapter or subchapter I of chapter 81.
(b) If an individual is entitled to an annuity under subchapter II, IV, or V, and the individual receives a lump-sum payment for compensation under section 8135 based on the disability or death of the same person, so much of the compensation as has been paid for a period extended beyond the date payment of the annuity commences, as determined by the Department of Labor, shall be refunded to that Department for credit to the Employees Compensation Fund. Before the individual may receive the annuity, the individual shall
(1) refund to the Department of Labor the amount representing the commuted compensation payments for the extended period; or
(2) authorize the deduction of the amount from the annuity.

Deductions from the annuity may be made from accrued or accruing payments. The amounts deducted and withheld from the annuity shall be transmitted to the Department of Labor for reimbursement to the Employees Compensation Fund. When the Department of Labor finds that the financial circumstances of an individual entitled to an annuity under subchapter II, IV, or V warrant deferred refunding, deductions from the annuity may be prorated against and paid from accruing payments in such manner as the Department determines appropriate.

5 USC 8465 - Waiver, allotment, and assignment of benefits

(a) An individual entitled to an annuity payable from the Fund may decline to accept all or any part of the amount of the annuity by a waiver signed and filed with the Office.

(b) An individual entitled to an annuity payable from the Fund may make allotments or assignments of amounts from the annuity for such purposes as the Office considers appropriate.

5 USC 8466 - Application for benefits

(a) No payment of benefits based on the service of an employee or Member shall be made from the Fund unless an application for payment of the benefits is received by the Office before the one hundred and fifteenth anniversary of the birth of the employee or Member.
(b) Notwithstanding subsection (a), after the death of an employee, Member, or annuitant, or former employee or Member, a benefit based on the service of such employee, Member, or annuitant, or former employee or Member, shall not be paid under subchapter II or IV of this chapter unless an application therefor is received by the Office within 30 years after the death or other event which establishes the entitlement to the benefit.
(c) Payment due a minor, or an individual mentally incompetent or under other legal disability, may be made to the person who is constituted guardian or other fiduciary by the law of the State of residence of the claimant or is otherwise legally vested with the care of the claimant or his estate. If a guardian or other fiduciary of the individual under legal disability has not been appointed under the law of the State of residence of the claimant, payment may be made to any person who, in the judgment of the Office, is responsible for the care of the claimant, and the payment bars recovery by any other person.

5 USC 8467 - Court orders

(a) Payments under this chapter which would otherwise be made to an employee, Member, or annuitant (including an employee, Member, or annuitant as defined in section 8331) based on service of that individual shall be paid (in whole or in part) by the Office or the Executive Director, as the case may be, to another person if and to the extent expressly provided for in the terms of
(1) any court decree of divorce, annulment, or legal separation, or the terms of any court order or court-approved property settlement agreement incident to any court decree of divorce, annulment, or legal separation; or
(2) any court order or other similar process in the nature of garnishment for the enforcement of a judgment rendered against such employee, Member, or annuitant, for physically, sexually, or emotionally abusing a child.

In the event that the Office or the Executive Director, as the case may be, is served with more than 1 decree, order, or other legal process with respect to the same moneys due or payable to any individual, such moneys shall be available to satisfy such processes on a first-come, first-served basis, with any such process being satisfied out of such moneys as remain after the satisfaction of all such processes which have been previously served.

(b) Subsection (a) shall apply only to payments made by the Office or the Executive Director under this chapter after the date on which the Office or the Executive Director (as the case may be) receives written notice of such decree, order, other legal process, or agreement, and such additional information and documentation as the Office or the Executive Director may require.
(c) For the purpose of this section
(1) the term judgment rendered for physically, sexually, or emotionally abusing a child means any legal claim perfected through a final enforceable judgment, which claim is based in whole or in part upon the physical, sexual, or emotional abuse of a child, whether or not that abuse is accompanied by other actionable wrongdoing, such as sexual exploitation or gross negligence; and
(2) the term child means an individual under 18 years of age.

5 USC 8468 - Annuities and pay on reemployment

(a) If an annuitant, except a disability annuitant whose annuity is terminated because of the annuitants recovery or restoration of earning capacity, becomes employed in an appointive or elective position, an amount equal to the annuity allocable to the period of actual employment shall be deducted from the annuitants pay, except for lump-sum leave payment purposes under section 5551. Unless the annuitants appointment is on an intermittent basis or is to a position as a justice or judge (as defined by section 451 of title 28) or as an employee subject to another retirement system for Government employees, or unless the annuitant is serving as President, deductions for the Fund shall be withheld from the annuitants pay under section 8422 (a) and contributions under section 8423 shall be made. The deductions and contributions referred to in the preceding provisions of this subsection shall be deposited in the Treasury of the United States to the credit of the Fund. The annuitants lump-sum credit may not be reduced by annuity paid during the reemployment.
(b) 
(1) 
(A) If an annuitant subject to deductions under the second sentence of subsection (a) serves on a full-time basis for at least 1 year, or on a part-time basis for periods equivalent to at least 1 year of full-time service, the annuitants annuity on termination of reemployment shall be increased by an annuity computed under section 8415 (a) through (h) as may apply based on the period of reemployment and the basic pay, before deduction, averaged during the reemployment.
(B) 
(i) If the annuitant is receiving a reduced annuity as provided in section 8419, the increase in annuity payable under subparagraph (A) is reduced by 10 percent and the survivor annuity or combination of survivor annuities payable under section 8442 or 8445 (or both) is increased by 50 percent of the increase in annuity payable under subparagraph (A), unless, at the time of claiming the increase payable under subparagraph (A), the annuitant notifies the Office in writing that the annuitant does not desire the survivor annuity to be increased.
(ii) If an annuitant who is subject to the deductions referred to in subparagraph (A) dies while still reemployed, after having been reemployed for not less than 1 year of full-time service (or the equivalent thereof, in the case of full-time[1] employment), the survivor annuity payable is increased as though the reemployment had otherwise terminated.
(2) 
(A) If an annuitant subject to deductions under the second sentence of subsection (a) serves on a full-time basis for at least 5 years, or on a part-time basis for periods equivalent to at least 5 years of full-time service, the annuitant may elect, instead of the benefit provided by paragraph (1), to have such annuitants rights redetermined under this chapter.
(B) If an annuitant who is subject to the deductions referred to in subparagraph (A) dies while still reemployed, after having been reemployed for at least 5 years of full-time service (or the equivalent thereof in the case of part-time employment), any person entitled to a survivor annuity under section 8442 or 8445 based on the service of such annuitant shall be permitted to elect, in accordance with regulations prescribed by the Office of Personnel Management, to have such persons rights under subchapter IV redetermined. A redetermined survivor annuity elected under this subparagraph shall be in lieu of an increased annuity which would otherwise be payable in accordance with paragraph (1)(B)(ii).
(3) If an annuitant subject to deductions under the second sentence of subsection (a) serves on a full-time basis for a period of less than 1 year, or on a part-time basis for periods equivalent to less than 1 year of full-time service, the total amount withheld under section 8422 (a) from the annuitants basic pay for the period or periods involved shall, upon written application to the Office, be payable to the annuitant (or the appropriate survivor or survivors, determined in the order set forth in section 8424 (d)).
(c) This section does not apply to an individual appointed to serve as a Governor of the Board of Governors of the United States Postal Service.
(d) If an annuitant becomes employed as a justice or judge of the United States, as defined by section 451 of title 28, the annuitant may, at any time prior to resignation or retirement from regular active service as such a justice or judge, apply for and be paid, in accordance with section 8424 (a), the amount (if any) by which the lump-sum credit exceeds the total annuity paid, notwithstanding the time limitation contained in such section for filing an application for payment.
(e) A reference in this section to an annuity shall not be considered to include any amount payable from a source other than the Fund.
(f) 
(1) The Director of the Office of Personnel Management may, at the request of the head of an Executive agency
(A) waive the application of the preceding provisions of this section on a case-by-case basis for employees in positions for which there is exceptional difficulty in recruiting or retaining a qualified employee; or
(B) grant authority to the head of such agency to waive the application of the preceding provisions of this section, on a case-by-case basis, for an employee serving on a temporary basis, but only if, and for so long as, the authority is necessary due to an emergency involving a direct threat to life or property or other unusual circumstances.
(2) The Office shall prescribe regulations for the exercise of any authority under this subsection, including criteria for any exercise of authority and procedures for terminating a delegation of authority under paragraph (1)(B).
(g) 
(1) If warranted by circumstances described in subsection (f)(1)(A) or (B) (as applicable), the Director of the Administrative Office of the United States Courts shall, with respect to an employee in the judicial branch, have the same waiver authority as would be available to the Director of the Office of Personnel Management, or a duly authorized agency head, under subsection (f) with respect to an employee of an Executive agency.
(2) Authority under this subsection may not be exercised with respect to a justice or judge of the United States, as defined in section 451 of title 28.
(h) 
(1) If warranted by circumstances described in subsection (f)(1)(A) or (B) (as applicable), an official or committee designated in paragraph (2) shall, with respect to the employees specified in the applicable subparagraph of such paragraph, have the same waiver authority as would be available to the Director of the Office of Personnel Management, or a duly authorized agency head, under subsection (f) with respect to an employee of an Executive agency.
(2) Authority under this subsection may be exercised
(A) with respect to an employee of an agency in the legislative branch, by the head of such agency;
(B) with respect to an employee of the House of Representatives, by the Committee on House Oversight of the House of Representatives; and
(C) with respect to an employee of the Senate, by the Committee on Rules and Administration of the Senate.
(3) Any exercise of authority under this subsection shall be in conformance with such written policies and procedures as the agency head, the Committee on House Oversight of the House of Representatives, or the Committee on Rules and Administration of the Senate (as applicable) shall prescribe, consistent with the provisions of this subsection.
(4) For the purpose of this subsection, agency in the legislative branch, employee of the House of Representatives, employee of the Senate, and congressional employee each has the meaning given to it in section 5531 of this title.
(i) 
(1) For the purpose of subsections (f) through (h), Executive agency shall not include the Government Accountability Office.
(2) An employee as to whom a waiver under subsection (f), (g), or (h) is in effect shall not be considered an employee for purposes of this chapter or chapter 83 of this title.
[1] So in original. Probably should be “part-time”.

5 USC 8469 - Withholding of State income taxes

(a) The Office shall, in accordance with this section, enter into an agreement with any State within 120 days of a request for agreement from the proper State official. The agreement shall provide that the Office shall withhold State income tax in the case of the monthly annuity of any annuitant who voluntarily requests, in writing, such withholding. The amounts withheld during any calendar quarter shall be held in the Fund and disbursed to the States during the month following that calendar quarter.
(b) An annuitant may have in effect at any time only one request for withholding under this section, and an annuitant may not have more than two such requests in effect during any one calendar year.
(c) Subject to subsection (b), an annuitant may change the State designated by that annuitant for purposes of having withholdings made, and may request that the withholdings be remitted in accordance with such change. An annuitant also may revoke any request of that annuitant for withholding. Any change in the State designated or revocation is effective on the first day of the month after the month in which the request or the revocation is processed by the Office, but in no event later than on the first day of the second month beginning after the day on which such request or revocation is received by the Office.
(d) This section does not give the consent of the United States to the application of a statute which imposes more burdensome requirements on the United States than on employers generally, or which subjects the United States or any annuitant to a penalty or liability because of this section. The Office may not accept pay from a State for services performed in withholding State income taxes from annuities. Any amount erroneously withheld from an annuity and paid to a State by the Office shall be repaid by the State in accordance with regulations issued by the Office.
(e) For the purpose of this section
(1) the term State means a State, the District of Columbia, or any territory or possession of the United States; and
(2) the term annuitant includes a survivor who is receiving an annuity from the Fund.

5 USC 8470 - Exemption from legal process; recovery of payments

(a) An amount payable under subchapter II, IV, or V of this chapter is not assignable, either in law or equity, except under the provisions of section 8465 or 8467, or subject to execution, levy, attachment, garnishment or other legal process, except as otherwise may be provided by Federal laws.
(b) Recovery of payments under subchapter II, IV, or V of this chapter may not be made from an individual when, in the judgment of the Office, the individual is without fault and recovery would be against equity and good conscience. Withholding or recovery of money paid under subchapter II, IV, or V of this chapter on account of a certification or payment made by a former employee of the United States in the discharge of his official duties may be made only if the head of the agency on behalf of which the certification or payment was made certifies to the Office that the certification or payment involved fraud on the part of the former employee.
