Federal Employees Retirement System (FERS)

The Federal Employees Retirement System is the retirement plan covering virtually all federal civilian employees hired after 1983. FERS is a three-legged stool: a defined-benefit pension (the Basic Benefit), Social Security, and the Thrift Savings Plan (TSP) — the federal government's 401(k)-equivalent. Together, these three components are designed to provide federal workers with retirement security that rivals or exceeds most private-sector packages. The Basic Benefit alone pays a pension based on your highest 3 years of salary multiplied by your years of service — and the government automatically contributes 1% of your pay to your TSP account (plus matches up to 4% more). About 2.0 million current employees (down from ~2.2M in early 2025 after the Trump administration's workforce reductions) and roughly 2.7 million annuitants participate in FERS.

Current Law (2026)

Legal Authority

• 5 U.S.C. § 8401 — Definitions (defines the FERS system, covered employees, creditable service, basic pay, and key terms)
• 5 U.S.C. § 8410 — Eligibility for annuity (no employee may receive a FERS annuity unless they have completed at least 5 years of creditable civilian service)
• 5 U.S.C. § 8411 — Creditable service (enumerates what counts toward retirement — civilian service, military service with deposit, and certain other periods)
• 5 U.S.C. § 8412 — Immediate retirement (age 62 + 5 years; age 60 + 20 years; MRA + 30 years — three paths to full retirement)
• 5 U.S.C. § 8413 — Deferred retirement (employees who separate before retirement eligibility but have 5+ years of creditable service may receive a deferred annuity starting at age 62)
• 5 U.S.C. § 8414 — Early retirement (voluntary early retirement authority — age 50 + 20 years or any age + 25 years, available during agency downsizing, RIF, or reorganization)
• 5 U.S.C. § 8415 — Computation of basic annuity (1% of high-3 average salary × years of creditable service; 1.1% multiplier for employees retiring at age 62 or later with 20+ years of service)
• 5 U.S.C. § 8420a — Alternative forms of annuity (lump-sum options and other annuity forms)
• 5 U.S.C. § 8432 — Contributions to Thrift Savings Plan (employee contributions, government automatic 1% contribution, and government matching contributions up to 5%)
• 5 U.S.C. § 8440a — Thrift Savings Plan investment options (TSP fund choices including government securities, fixed income, common stock index, small-cap, international, and lifecycle funds)

How It Works

FERS retirement income comes from three sources: the Basic Benefit (a traditional defined-benefit pension paying a fixed monthly amount for life), Social Security (FERS employees pay FICA taxes and earn Social Security credits just like private-sector workers), and the Thrift Savings Plan (a defined-contribution account like a 401(k) but with extremely low fees and a generous government match). The Basic Benefit pension is calculated as 1% × your high-3 average salary × years of creditable service — the "high-3" being the average of your three highest consecutive years of basic pay. Retiring at age 62 or later with at least 20 years of service raises the multiplier to 1.1%: 30 years of service with a $100,000 high-3 produces a $33,000/year pension (vs. $30,000 at 1.0%). Retirement eligibility follows three main paths: Minimum Retirement Age (MRA, between 55 and 57 depending on birth year) with 30 years of service; age 60 with 20 years; or age 62 with just 5 years. Employees who separate before reaching retirement eligibility with at least 5 years of service earn a deferred annuity starting at age 62.

The TSP match is one of the strongest employer retirement contributions of any plan: the government automatically contributes 1% of basic pay regardless of employee contributions, then matches dollar-for-dollar on the first 3% of employee contributions and 50 cents on the dollar on the next 2%, for a maximum government contribution of 5% — but only if the employee contributes at least 5%. TSP funds include extremely low-cost index options: the C Fund (S&P 500), S Fund (small-cap), I Fund (international), F Fund (bonds), G Fund (government securities), and L Funds (lifecycle target-date funds). Employee pension contribution rates depend on hire date: original FERS (before 2013) contributes 0.8% of pay; FERS-RAE (2013) contributes 3.1%; FERS-FRAE (2014 or later) contributes 4.4% — all receiving the same pension formula and TSP match. A married FERS retiree's annuity automatically includes a 50% survivor benefit (the surviving spouse receives 50% of the unreduced annuity), with the cost reflected as a reduction in the employee's own annuity during their lifetime; a 25% survivor benefit is available at a smaller reduction.

How It Affects You

State Variations

• TSP withdrawals are subject to standard federal and state income tax rules

Implementing Regulations

• 5 CFR Part 842 — FERS Basic Annuity: detailed eligibility and computation rules including special categories — law enforcement officers and firefighters (retire at 50 with 20 years or any age with 25 years at 1.7%/year rate); air traffic controllers (mandatory separation at 56 with 20 years); nuclear materials couriers; customs and border protection officers (covered since 2007, with mandatory separation at 57). Each special category has its own contribution rate and benefit multiplier. Subpart D covers general annuity computation; Subpart F governs survivor elections (joint-life vs. single-life annuity); Subpart G covers alternative forms of annuity (lump-sum options, specific rules apply)

• 5 CFR Part 837 — Reemployment of Annuitants. Governs what happens to CSRS and FERS retirement benefits when a federal retiree returns to federal employment. This is a common situation — agencies often re-hire recent retirees for technical expertise, vacancy coverage, or critical-needs positions. Key provisions:

  • § 837.201 — Annuitant status persists: a reemployed annuitant remains an annuitant throughout the period of reemployment unless their annuity is specifically terminated under the rules below; the annuitant continues receiving their pension from OPM during federal re-employment unless one of the termination triggers applies
  • § 837.202 — Annuities that terminate on reemployment: a FERS disability annuitant who OPM has determined is recovered or restored to earning capacity before reemployment must have their annuity terminated upon re-hire; for non-disability annuitants, reemployment generally does not terminate the annuity
  • § 837.203 — Annuities that are suspended: an annuity is suspended (not terminated) when the annuitant is appointed as a federal judge (defined under 28 U.S.C. § 451) or receives an interim Presidential appointment to a position requiring Senate confirmation; suspension means the annuity payments stop during the appointment period but rights are preserved; the annuity resumes when the appointment ends
  • § 837.303 — The annuity offset rule: when an annuitant continues receiving their annuity during reemployment (the most common situation), the reemployed annuitant's agency salary is offset (reduced) by the amount of the annuity; this prevents true double-dipping: if your annuity is $60,000/year and the new position pays $100,000/year, the agency pays you $40,000 and OPM pays your $60,000 annuity — total compensation equals the salary rate, not salary plus pension; agencies cannot pay the annuitant more than this offset-adjusted amount without a specific dual compensation waiver from OPM or other statutory authority
  • § 837.103 — Notice to OPM: the hiring agency must notify OPM in writing on or before the date of appointment; the notice must include the annuitant's name, date of birth, SSN, and retirement claim number; OPM uses this to coordinate annuity offset calculation and ensure correct benefit administration
  • § 837.401 — Disability annuitant reemployment: disability annuitants (FERS retirees receiving disability benefits) may be reemployed in any position for which they are qualified; if their earnings in reemployment reach or exceed their most recent pre-retirement pay adjusted for inflation, OPM may find them "restored to earning capacity" and terminate the disability annuity

  Dual compensation waivers (which exempt certain re-employed annuitants from the offset rule entirely, allowing them to receive both full salary and full annuity) require statutory authority or OPM approval; waivers are commonly granted for critical-shortage occupations, cyber and intelligence positions, and certain medical/scientific roles where agencies have difficulty hiring non-retirees. A re-employed annuitant with a waiver is genuinely receiving both the pension and the full salary simultaneously — a significant total compensation advantage.

• 5 CFR Part 838 — Court Orders Affecting Retirement Benefits: governs how OPM implements divorce and legal separation court orders affecting CSRS and FERS annuities; the federal analog to private-sector QDROs. Key rules: court orders must specifically refer to "civil service retirement benefits" to be enforceable; OPM does not "approve" court orders in advance but will notify the employee when a court order is received; former spouses must apply in writing to OPM to receive benefits; OPM's "court order acceptable for processing" determination is appealable to the Merit Systems Protection Board. Covers annuity sharing, survivor benefit elections, and refunds of employee contributions

• 5 CFR Part 841 — FERS General Administration: the operational rules governing how the FERS basic benefit is funded, administered, and paid. Key subparts:

  • Subpart D (§§ 841.401–841.417) — Government Costs: agencies pay an "employer normal cost" percentage to OPM each pay period to prefund FERS benefits; the normal cost rate is set actuarially by OPM each year based on projected benefit costs; agencies that under-fund or fail to make required contributions incur interest charges under § 841.412
  • Subpart E (§§ 841.501–841.508) — Employee Deductions and Government Contributions: employee contribution rate is 0.8% of basic pay for employees hired before 2013 ("FERS"), 3.1% for those hired January 1, 2013 – December 31, 2013 ("FERS-RAE"), and 4.4% for those hired January 1, 2014 and later ("FERS-FRAE"); the government's employer share is substantially higher than the employee share, making the employee contribution only a fraction of the total FERS funding requirement
  • Subpart G (§§ 841.701–841.708) — Cost-of-Living Adjustments: the FERS COLA rules differ materially from CSRS. Under FERS: no COLA until age 62 (a disability retiree may receive a reduced COLA before 62, and certain special categories such as law enforcement/firefighter retirees receive COLA at any age). At 62 and above: when the CPI-W increase is ≤ 2%, the FERS COLA equals the full CPI-W increase; when CPI-W is between 2% and 3%, the FERS COLA is capped at 2%; when CPI-W is ≥ 3%, the FERS COLA equals CPI-W minus 1 percentage point. This formula means FERS retirees always receive less purchasing power protection than CSRS retirees (who get the full CPI-W regardless of the inflation rate), making the FERS pension less valuable in high-inflation periods
  • Subpart J (§§ 841.1001–841.1007) — State Income Tax Withholding: OPM enters Federal-State agreements with each state to withhold state income taxes from FERS annuity payments; OPM processes state tax withholding requests monthly against the annuity roll; either party may terminate an agreement on 60 days' notice

• 5 CFR Part 839 — Correction of Retirement Coverage Errors under the Federal Erroneous Retirement Coverage Corrections Act (FERCCA) (enacted September 19, 2000 as Title II of Pub. L. 106-265; 71 sections across 13 subparts): addresses the situation where a federal employee was placed in the wrong retirement system — most commonly, hired under FERS but erroneously put in CSRS, or vice versa — for an extended period:

  • Subpart B — Eligibility: an employee has a "qualifying retirement coverage error" if they were in the wrong plan for any period; the error can be identified years or even decades after it occurred — employees already retired can apply
  • Subpart C — Employer Notification: agencies must provide written notice to each affected employee once they identify a coverage error; the notice must describe the error, explain the employee's election options, and state appeal rights
  • Subpart D/E — Election Options: an employee may elect to (a) stay in their current (incorrect) plan retroactively validated, (b) switch to the correct plan, or (c) in certain cases, choose a hybrid arrangement; elections are irrevocable
  • Subpart F — Making an Election: employee has a specified period after notification to make an election; failure to elect results in placement in the correct plan by default
  • Subpart G — Errors That Don't Permit an Election: certain error types result in automatic correction without an employee election
  • Subpart H — Adjusting Deductions and Contributions: after an election, the agency must adjust retroactive deductions and government contributions; refunds or additional charges may result
  • Subpart I — Social Security Taxes: CSRS employees are not covered by Social Security; FERS employees are; a coverage switch triggers retroactive Social Security tax adjustments — the IRS and SSA coordinate with OPM
  • Subpart J — Lost TSP Earnings: employees corrected from CSRS to FERS who make TSP make-up contributions are entitled to lost earnings (the investment growth that would have accrued) computed under TSP Board regulations (5 CFR Parts 1605–1606); OPM computes lost earnings and coordinates payment
  • Subpart K — Effect of Election: retirement benefits are computed as if the employee had been correctly placed from the start; actuarial reductions apply if the employee keeps TSP government contributions (the government contribution advantage is offset against the annuity through a present-value calculation, §§ 1212.1118–1212.1119)
  • Subpart L — Discretionary OPM Actions: OPM may reimburse necessary legal expenses and compensate for monetary losses (additional Social Security taxes paid, legal fees, out-of-pocket costs) that directly resulted from the error — these decisions are in OPM's sole discretion and are not subject to MSPB appeal (§§ 839.1201–839.1206)
  • Subpart M — Appeals: employees may appeal most employer and OPM decisions to the Merit Systems Protection Board; after exhausting administrative remedies, judicial review is available under the Federal Tort Claims Act

• 5 CFR Part 845 — Federal Employees Retirement System: Debt Collection (29 sections across 4 subparts — OPM's rules for recovering FERS overpayments, the waiver standard for excusing those overpayments, and the process by which other federal agencies can request OPM to offset annuity payments to recover debts owed to them; implements 5 U.S.C. § 8470):

  • Prohibition against unauthorized collection (§ 845.103): debts may be recovered from FERS basic benefits only when expressly authorized by federal statute; OPM cannot invent new offset authorities — each collection method must trace to specific statutory authority
  • OPM fault rule (§ 845.104): if OPM causes an overpayment by its own administrative error — for example, failing to adjust an annuity after a court order or change in status — OPM bears the error and the amount is not automatically a debt; the overpayment becomes a debt only when the annuitant is notified and given a demand letter
  • Collection procedures (Subpart B, §§ 845.201–845.209): before collection begins, OPM must provide written notice of the debt amount, reason, payment deadline, right to inspect records, right to request a waiver, and right to dispute; collection may occur through administrative offset against lump-sum payments or recurring annuity payments, from other federal payments owed to the debtor, by referral to a private collection agency, or by DOJ litigation (§ 845.209); OPM may report delinquent debts to consumer reporting agencies if the debtor does not respond to the demand (§ 845.207); installment repayment plans are available for large debts that cannot be collected in one payment (§ 845.407)
  • Waiver standard (Subpart C, §§ 845.301–845.307): FERS overpayments may be waived under 5 U.S.C. § 8470(b) when two conditions are met: (1) the annuitant is without fault — meaning they did not commit any act or omission that caused the overpayment — and (2) recovery would be against equity and good conscience — meaning it would cause financial hardship, the annuitant detrimentally relied on the payment, or collection would be inequitable regardless of hardship; OPM must prove by a preponderance of evidence that an overpayment occurred; the annuitant must prove waiver grounds by substantial evidence (§ 845.307); waiver is precluded if the overpayment was obtained by fraud or made to an estate (§ 845.306)
  • Agency offset requests (Subpart D, §§ 845.401–845.408): other federal agencies may request OPM to offset annuity payments to recover debts owed by FERS annuitants; the requesting agency must certify the debt is valid, final, and not currently under appeal; OPM offsets from the annuity in installments if the debt is too large for a one-time deduction (§ 845.407); fraud-related claims require referral to DOJ before OPM takes action (§ 845.408)

• 5 CFR Parts 842–847 — Additional FERS administrative rules (coverage, annuity computations, survivors, disability, deposits/redeposits, and nonappropriated fund retirement coverage elections)

• 5 CFR Part 831 — Civil Service Retirement System (CSRS) administration (232 sections across 24 subparts): the companion retirement system for federal civilian employees hired before January 1, 1984 — about 1.5 million retirees. CSRS requires an employee contribution of 7% of basic pay (vs. 0.8–4.4% for FERS) and provides a larger pension — approximately 2% of high-3 salary per year — with no Social Security coverage and no TSP government match. Key subpart coverage:

  • Subpart A — Administration and claims: OPM adjudicates all CSRS claims; SF 2806 (Individual Retirement Record) is the basic record; initial OPM decisions may be reviewed within 30 days; appeals go to the Merit Systems Protection Board (§ 831.110)
  • Subpart B — Coverage: defines who is subject to CSRS — most career federal employees and Members of Congress hired before 1984; specifically excludes certain temporary, part-time, and intermittent workers; CSRS Offset employees (hired before 1984 but had a break in service) are covered by both CSRS and OASDI, with OASDI contributions deducted from the 7% CSRS deduction
  • Subpart E — Eligibility: immediate retirement at age 62 + 5 years, age 60 + 20 years, age 55 + 30 years; voluntary early retirement at 50 + 20 or any age + 25 during agency downsizing; deferred retirement available if separated with 5+ years
  • Subpart F — Survivor Annuities (33 sections — largest): surviving spouse receives 55% of the employee's unreduced annuity (vs. 50% for FERS); employee pays a cost-of-living reduction (either a fixed amount or 10% of the unreduced annuity); former spouses may receive survivor benefits under court orders; insurable interest elections available for dependents or other individuals
  • Subpart G — Computation of annuities: 1.5% per year for the first 5 years, 1.75% per year for years 6-10, 2% per year for all years over 10 — creating a substantially larger benefit than FERS for long-service employees (a 30-year CSRS employee gets ~56.25% of high-3 salary, vs. 30% under FERS)
  • Subpart H/I/P — Special-category employees: law enforcement officers and firefighters (Subpart I) may retire at age 50 with 20 years at an enhanced rate; nuclear materials couriers (Subpart H) and customs and border protection officers (Subpart P) each have separate contribution rates, eligibility ages, and benefit multipliers reflecting hazardous duty classifications
  • Subpart J — CSRS Offset: employees covered by both CSRS and Social Security; contribution is 7% minus the OASDI tax rate; at retirement, annuity is offset by the Social Security benefit attributable to CSRS Offset service; protects the employee's total benefit level while reducing CSRS cost
  • Subpart L — Disability Retirement (12 sections): requires 5+ years of creditable service; disability must be current and documented with SF 2824 supporting package; earning capacity is considered "restored" if annual income from work equals 80% or more of the current salary of the position held at retirement — triggers termination of disability annuity; OPM may require medical re-examination annually until age 60
  • Subpart Q — Phased Retirement (24 sections): allows employees to work part-time (minimum 20 hours/week) while receiving a partial annuity — 50% of the annuity while working half-time; designed to facilitate knowledge transfer and transition; phased retiree must be mentoring; available at any agency with OPM approval
  • Subpart T — Lump-sum payments: employees who separate or die may receive lump-sum payment of remaining contributions plus interest; surviving spouse may waive the survivor annuity in favor of lump sum in certain cases
  • Subpart U — Military service deposits: CSRS employees can receive service credit for military service by depositing 7% of military basic pay plus interest; no credit without deposit for post-1956 military service

• 5 CFR Part 1600–1690 — Thrift Savings Plan (TSP) (participant eligibility, contributions, investment options, loans, withdrawals, fund management)

• 5 CFR Part 846 — Federal Employees Retirement System — Elections of Coverage (28 sections across 4 subparts — OPM's rules governing the transition from CSRS to FERS for employees who were under CSRS when FERS was created in 1986 and subsequently elected FERS coverage; primarily historical but still operative for computing the mixed-service annuities of employees who transferred):

  • § 846.201 — Original transfer window: employees covered by CSRS as of June 30, 1987 could elect to transfer to FERS during a one-time window from July 1 through December 31, 1987; elections were irrevocable once effective; former employees who returned to federal service after June 30, 1987 in a position subject to FERS coverage fell under FERS automatically
  • § 846.202 — Former spouse consent: a CSRS-to-FERS election could not take effect without written consent of any former spouse entitled to CSRS survivor benefits — protecting former spouses who had divorce court orders awarding them a share of the CSRS annuity from having their rights eliminated by the employee's election
  • § 846.204 — Belated elections: employing offices could accept a belated CSRS-to-FERS election within 6 months after the expiration of the regular election window if the employee did not receive the required FERS transfer handbook on time; the agency had to document the cause and receive OPM authorization
  • § 846.302 — Crediting CSRS service under FERS: for an employee who transferred to FERS, civilian service performed before FERS coverage is creditable under FERS if the correct retirement deductions (7% for regular CSRS, or 7% for the other system) were withheld; service performed before January 1, 1987, where 1.3% of basic pay was withheld as part of the CSRS/Social Security integrated system, is also creditable
  • § 846.304 — Computing mixed CSRS/FERS annuities: the basic annuity for a CSRS-to-FERS transferee is the sum of two components: (1) the CSRS portion — the accrued CSRS benefit based on years of CSRS service, computed under CSRS rules as of the transfer date; and (2) the FERS portion — the annuity earned under FERS rules for service after the transfer; the two portions are added together, giving the employee credit for all service under the more favorable computation for each period
  • § 846.401 — Refund of excess CSRS contributions: employees who transferred to FERS may receive a refund of CSRS contributions made before the transfer for service that is counted under the FERS computation in § 846.304(c); employees may alternatively withdraw all CSRS contributions under § 846.402 — but withdrawing all CSRS contributions forfeits the CSRS portion of the annuity for that service period
  • §§ 846.701–846.711 — 1998 open enrollment: Congress authorized a second CSRS-to-FERS transfer window in 1998 for employees who did not transfer in 1987; employees not covered by FERS who were employed on January 1, 1998, could elect FERS coverage during the 1998 open enrollment period; the election followed the same irrevocability, former-spouse consent, and service-crediting rules as the original transfer; elections were effective the first day of the pay period after OPM received the election

  The Part 846 transfer rules matter primarily for employees with long CSRS service before the 1987 or 1998 elections, whose retirement computations involve both a CSRS and a FERS component. The most common practical issue: employees who transferred to FERS and later took a refund of their CSRS contributions gave up the CSRS credit for those service years — this decision (which many employees made without fully understanding the long-term cost) permanently reduces the CSRS component of their mixed annuity.

• 5 CFR Part 1650 — Methods of Withdrawing Funds from the Thrift Savings Plan (27 sections across 4 subparts — the Federal Retirement Thrift Investment Board's rules governing how TSP participants access their account balances after separation from government service and through in-service withdrawal options; implements 5 U.S.C. § 8351):

  • § 1650.2 — Eligibility and general rules: a participant who has separated from government service may elect a distribution by any method in Part 1650; separated participants with accounts of $200 or more must submit a distribution election (§ 1650.22); accounts under $200 are automatically distributed after 60 days following separation if no election is made (§ 1650.23)
  • § 1650.11 — Post-employment distribution options: participants may elect any combination of (1) a single payment, (2) a series of installment payments, (3) a life annuity, or (4) leaving funds in the TSP (subject to required minimum distributions); elections for partial distributions leave the remainder available for future elections
  • § 1650.12 — Single payment: a participant may elect distribution of all or a portion of their account in a single payment; the minimum amount for a partial single payment is $1,000
  • § 1650.13 — Installment payments: monthly, quarterly, or annual installments paid in either (1) a fixed dollar amount of the participant's choosing or (2) amounts calculated using the participant's life expectancy (IRS tables); participants may change the installment amount or frequency once per year; installment payments continue until the account is depleted or the participant changes to another method
  • § 1650.14 — Life annuities: participants may use all or a portion of their traditional or Roth TSP balance to purchase a life annuity through the TSP record keeper; annuity options include single-life, joint with spouse, and joint with survivor annuity; once purchased, the annuity is irrevocable
  • § 1650.16 — Required minimum distributions (RMDs): separated participants must begin taking RMDs by the required beginning date (generally April 1 of the year following the year they turn age 73 under current law); each subsequent year's RMD must be taken by December 31; the TSP calculates RMD amounts using the IRS Uniform Lifetime Table
  • § 1650.25 — Rollovers: the TSP record keeper will, at the participant's election, directly roll over any eligible rollover distribution to an IRA, 401(k), 403(b), or other eligible plan; rollovers avoid withholding and preserve tax deferral; Roth TSP balances may only be rolled to a Roth IRA or designated Roth account
  • § 1650.31 — Age-based in-service withdrawals: participants who have reached age 59½ and have not separated from government service may make a one-time or multiple partial withdrawals from their TSP account; in-service age-based withdrawals are not subject to the 10% early withdrawal penalty; after age 59½, participants may make multiple age-based withdrawals
  • § 1650.32 — Financial hardship in-service withdrawals: current federal employees who certify a financial hardship may withdraw from their own contributions (not agency contributions or earnings on those contributions); no limit on the number of hardship withdrawals, but participants must wait 30 days between requests; hardship withdrawals are subject to the 10% early withdrawal penalty if the participant is under 59½ and do not qualify as eligible rollovers

  The TSP withdrawal rules are among the most consequential financial decisions a federal employee or retiree faces. Key practical notes: Roth TSP balances (contributions from after-tax pay) are subject to different rollover rules than traditional TSP balances; installment payments based on life expectancy automatically comply with RMD rules; and a participant's survivor benefit elections (spousal rights, beneficiary designations) govern what happens to the TSP account at death. The TSP record keeper processes all withdrawal requests — participants initiate through tsp.gov or by calling the ThriftLine at 1-877-968-3778. 87 FR 31681 (May 25, 2022) contains the most recent major amendments to Part 1650.

• 5 CFR Part 848 — Phased Retirement (24 sections — OPM's regulations implementing the phased retirement option added to FERS by the MAP-21 Act (2012); allows eligible federal employees to begin drawing a partial annuity while continuing to work part-time, facilitating knowledge transfer and a gradual transition to full retirement; implements 5 U.S.C. § 8412a):

  • § 848.201 — Eligibility: to elect phased retirement, an employee must be retirement-eligible under FERS (meet the age and service requirements for an immediate retirement) and must have been employed on a full-time basis for at least 3 years immediately preceding the election; the 3-year full-time requirement prevents employees who recently converted to part-time from accessing the benefit
  • § 848.202 — Working percentage: the "working percentage" is the fraction of full-time hours the phased retiree will work, expressed as a percentage; the phased retirement annuity equals the working percentage subtracted from 100% — an employee working 50% receives a 50% annuity; an employee working 40% receives a 60% annuity; the default and most common arrangement is 50% work / 50% annuity
  • § 848.203 — Application process: to elect phased retirement, the employee submits a signed written request to an authorized agency official (not OPM directly); the agency official approves or denies the election; phased retirement is not an entitlement — agencies have discretion to approve or deny based on operational needs
  • § 848.204 — Effective date: phased employment begins on the first day of the first pay period after the agency approves the request, or a later date the employee requests; the phased retirement annuity begins on the same effective date
  • § 848.205 — FEHB and benefits status: a phased retiree is treated as a full-time employee for FEHB (Federal Employees Health Benefits) purposes — they pay the same employee premium share as a full-time employee, not the higher retiree share; this full-time FEHB treatment is one of the most significant financial advantages of phased retirement compared to simply reducing hours without retiring
  • § 848.301–848.303 — Returning to full employment: a phased retiree may elect (with agency approval) to end phased retirement and return to full-time employment status at any time; upon return, the phased retirement annuity terminates; all retirement rights are restored based on the law in effect at that time
  • § 848.401 — Application for full retirement: a phased retiree may elect to enter full retirement at any time by submitting an OPM retirement application; the phased retirement annuity terminates upon separation from service, and the composite annuity begins the following day
  • § 848.501 — Computation of phased retirement annuity: the phased retirement annuity = (100% minus working percentage) × the FERS annuity that would have been payable at the time of election (before survivor reduction); for a 50% working percentage, the phased annuity is 50% of the FERS benefit that would have been earned at that point
  • § 848.502 — Computation of composite annuity at final retirement: the final composite annuity is the sum of (1) the original phased retirement annuity component (adjusted for COLAs during the phased period), plus (2) a new FERS annuity component based on the part-time phased employment service — reflecting continued service and potential salary increases during the phased period
  • § 848.503 — COLA on phased annuity: the phased retirement annuity component receives cost-of-living adjustments during the phased period at the same rate as full retirees; this ongoing COLA protection preserves the real value of the phased annuity while the employee continues working
  • § 848.504 — No annuity supplement: a phased retiree is not eligible for the FERS Annuity Supplement — the bridge payment that compensates FERS retirees under age 62 for the Social Security benefit they cannot yet receive; this limitation is a meaningful disadvantage compared to full retirement for employees who retire before 62
  • § 848.601 — Service deposits: any outstanding civilian service deposits or redeposits that the employee wishes to make must be paid within 30 days of entering phased retirement; the window for curing service credit gaps closes quickly

  Phased retirement is available to any agency — there is no mandatory OPM pre-approval at the program level, though individual employee requests require agency approval. Employees should understand that the phased retirement decision involves permanent tradeoffs: the phased annuity begins earning COLAs earlier, but the annuity supplement is unavailable, and the composite final annuity computation involves two separate components. Payroll continues at the part-time salary rate, meaning total income (salary + phased annuity) during phased retirement may actually exceed pre-retirement full-time salary in some cases. Employees considering phased retirement should model both scenarios using the OPM annuity estimator at opm.gov/retirement-services before submitting their election.

• 5 CFR Part 844 — FERS Disability Retirement: OPM rules governing the FERS disability annuity for federal employees who become unable to perform their job duties due to illness or injury (implements 5 U.S.C. § 8461):

  • § 844.103 — Eligibility: an employee must have completed at least 18 months of FERS-creditable civilian service to be eligible; the disabling condition must prevent useful and efficient service in the employee's current position; OPM — not the employing agency — makes the final disability determination
  • § 844.201–844.203 — Application and timing: an application is timely only if filed with the employing agency before the employee separates from service, or with OPM within 1 year after separation; if the application is filed post-separation, the separation must have been involuntary or based on resignation under duress; applications require OPM's medical documentation form, physician statements, and agency certification of inability to accommodate
  • § 844.202 — Agency-initiated filings: an agency must file a disability retirement application on behalf of an employee when: the employee has 18+ months of service, the agency is unable to accommodate the disabling condition in the current position or any vacant position at the same grade/pay, and OPM approval is sought; agency-initiated applications protect both the employee's benefits and the agency's ability to fill the position
  • § 844.105 — Workers' compensation offset: an employee eligible for both a FERS disability annuity and federal workers' compensation (under 5 U.S.C. chapter 81) cannot receive both simultaneously; the employee must elect one or the other; workers' compensation is typically higher during the working years, while the FERS disability annuity may be preferable at age 62 when the annuity is recomputed at a higher rate
  • § 844.302 — Annuity computation before age 62: the disability annuity is computed differently for employees under 62 — it is not the standard FERS formula; instead, it is typically 60% of the high-3 average salary for the first year, then 40% thereafter, reduced by 100% of any Social Security disability benefit for which the employee is eligible (the "adjusted Social Security disability benefit" offset)
  • § 844.305 — Recomputation at age 62: on the annuitant's 62nd birthday, OPM recomputes the annuity using the standard FERS formula (years of creditable service × 1% × high-3 average salary), which for long-service employees typically results in a higher annuity than the disability computation
  • § 844.401–844.402 — Recovery and earning capacity: OPM may require medical examinations annually until age 60 to verify continuing disability; a disability annuity terminates if the annuitant recovers from the disabling condition; if an annuitant under age 60 earns 80% or more of the current basic pay for their former position in wages or self-employment during a calendar year, OPM considers earning capacity restored and may terminate the annuity

  FERS disability retirement is a meaningful safety net for federal employees but involves significant procedural complexity. The agency-initiated filing requirement is important: employees incapacitated by illness or injury may be unable to navigate OPM paperwork themselves — the agency's obligation to file ensures that eligible employees don't lose disability benefits simply because they were too ill to apply. The workers' compensation election (FECA vs. FERS disability annuity) involves a strategic calculation that changes over time as the relative values shift.

• 5 CFR Part 849 — Representative Payees: OPM rules governing when and how annuity payments under CSRS and FERS are made to a representative payee rather than directly to the annuitant (implements 5 U.S.C. § 8466a):

  • § 849.201 — When representative payments are made: OPM makes payments to a representative payee when the annuitant is: (a) a minor under 18; (b) mentally incompetent or under another legal disability; or (c) physically or mentally unable to manage or direct the management of their financial affairs; OPM may continue direct payments while searching for a suitable payee unless direct payment would cause substantial harm
  • § 849.203 — Evidence considered: OPM evaluates legal guardianship documents, medical evidence from treating physicians, and other statements about the annuitant's condition; a legal guardian appointment is strong — but not conclusive — evidence that a representative payee is needed; OPM may require additional documentation if the evidence is incomplete
  • § 849.302 — Order of preference: in selecting a representative payee, OPM prefers (in descending order): (1) a legal conservator or guardian appointed by a court; (2) a spouse, parent, or adult relative who has custody of the annuitant; (3) a friend or other person who has custody; (4) an authorized institution, such as a licensed care facility or nonprofit organization; the primary criterion throughout is the best interest of the annuitant, not the convenience of the payee
  • § 849.303 — Who cannot serve: a representative payee may not be under 18 (unless a custodial parent of the minor annuitant), convicted of misusing Social Security or federal annuity benefits, or incapable of managing the annuitant's funds; organizations convicted of related crimes are also barred
  • § 849.304 — Investigation before selection: OPM conducts an investigation before designating any individual or organization as representative payee, requiring proof of identity and verifying the applicant's relationship to the annuitant and suitability to serve
  • § 849.401–849.402 — Payee responsibilities: representative payees must apply all payments for the use and benefit of the annuitant; permitted uses include current maintenance (food, shelter, clothing), medical care, personal comfort items, and support of legal dependents; payees may invest conserved funds in safe, interest-bearing accounts for future annuitant needs
  • § 849.403 — Accountability reporting: representative payees must submit written accounting reports in the form and at the intervals OPM requires; reports document how funds were used and any funds conserved; OPM may audit payee records at any time
  • § 849.501–849.502 — Misuse and liability: misuse of benefits is defined as the representative payee's embezzlement or conversion of annuity payments for the payee's own use rather than the annuitant's benefit; a payee found to have misused funds is personally liable for repayment to OPM; OPM seeks restitution from the former payee and the annuitant is made whole from the retirement fund
  • § 849.602 — Return to direct payment: representative payments stop when the annuitant demonstrates mental and physical capacity to manage their own affairs; the annuitant's written request, supported by medical evidence, triggers OPM's review of whether direct payment is appropriate

  The representative payee framework protects retirement income for FERS and CSRS annuitants who are incapacitated — a population that includes elderly annuitants with dementia, individuals with serious mental illness, and minor beneficiaries. Unlike Social Security's representative payee system (which handles hundreds of thousands of cases annually), the federal retirement representative payee system is smaller but involves the same fiduciary obligations and accountability requirements. The order of preference tilts toward family/guardian over institutions — reflecting a policy preference for keeping benefit management within the annuitant's personal network when that network is trustworthy.

Additional OPM retirement administration regulations:

• 5 CFR Part 850 — Electronic Retirement Processing: OPM's rules for processing federal employee retirements electronically through the Employee Express system and agency HR systems; requires agencies to submit retirement applications and personnel data electronically to OPM's Retirement Services; addresses electronic transmission of retirement records, SF-50 data, leave and earnings statements, and supporting documentation; electronic processing reduces processing times compared to paper submissions; agencies that lack electronic submission capability must notify OPM; the Part governs data standards, transmission protocols, and correction procedures for electronically submitted retirement records

• 5 CFR Part 891 — Continued Coverage in Federal Employees Health Benefits Program for Retired Federal Employees: OPM rules governing continuation of FEHB coverage for federal employees who retire under FERS, CSRS, or other retirement systems; to continue FEHB into retirement, an employee must have been enrolled (or covered as a family member) for the 5 continuous years immediately before retirement — this "5-year rule" is the most common source of FEHB portability problems for federal employees who have gaps in enrollment; retired annuitants pay the same premium rate as active employees (both the employee and government shares), making FEHB one of the most valuable federal retirement benefits; Part 891 governs enrollment changes, premium billing, and coordination with Medicare after age 65

Recent Developments

The FERS-FRAE contribution increase (from 0.8% to 4.4% for employees hired after 2013) has been a significant concern for federal workforce recruitment — newer employees pay substantially more for the same pension benefit. TSP participation rates have improved since automatic enrollment was implemented (employees are auto-enrolled at 5% unless they opt out). The TSP's mutual fund window (launched 2022) allows participants to invest in thousands of additional funds beyond the core TSP options, though with higher fees. Congress has periodically considered proposals to reduce or eliminate the FERS pension for new hires, shifting entirely to TSP — none have passed. The Postal Service Reform Act of 2022 required postal employees to enroll in Medicare Part B, affecting the interaction between FEHB and Medicare for postal retirees under FERS.

In March 2026, OPM submitted the Annuity Supplement Earnings Report (RI 92-22) information collection for review, used by federal retirees receiving the annuity supplement to report annual earnings that may affect supplement eligibility.

• DOGE and federal employee deferred resignation (2025): OPM's January 2025 "Fork in the Road" deferred resignation offer — which approximately 75,000 employees accepted — raised FERS vesting and benefit questions for employees considering departure. Employees who accepted were told they would retain their benefits if they remained on paid administrative leave through September 2025; OPM guidance clarified that FERS service credit continued accruing during the administrative leave period. Employees near 5-year FERS vesting or 30-year retirement milestones faced especially complex calculations.
• OBBBA federal employee benefit cuts (proposed): The "One Big Beautiful Bill Act" included provisions to increase FERS employee contribution rates — requiring newer employees to contribute a larger percentage of salary toward their pension — as a federal workforce cost-reduction measure. The proposal would raise FERS contributions by approximately 1 percentage point for non-FRAE employees. Federal employee unions (AFGE, NTEU) vigorously opposed the change, arguing it amounted to a pay cut on top of hiring freezes and workforce reductions.
• TSP C Fund and federal employee investment returns: The TSP's C Fund (tracks the S&P 500) returned approximately 25% in 2023 and 24% in 2024, substantially benefiting federal employees with balanced allocations during DOGE uncertainty. Employees nearing retirement who shifted to the G Fund (Treasury securities) during the DOGE disruption period may have missed equity gains. OPM data showed increased TSP hardship withdrawal applications in 2025, correlating with federal workforce anxiety and some employees experiencing income disruption.
• Social Security Fairness Act impact on FERS retirees: The Social Security Fairness Act (enacted January 2025) repealed the Windfall Elimination Provision (WEP) and Government Pension Offset (GPO). Many FERS retirees who also have Social Security benefits from prior private-sector employment had their Social Security reduced by WEP — the repeal increased their combined retirement income. The average WEP-affected retiree saw a $360/month Social Security increase retroactive to December 2023. OPM and SSA coordinated to process the benefit adjustments.
