FERS Special Retirement Supplement (SRS)

The FERS Special Retirement Supplement is a bridge benefit paid to federal employees who retire before age 62. It approximates the Social Security benefit earned through federal service and ends when the retiree turns 62. Enter it as a fixed annual amount with no indexing. Stratum auto-computes the end year as the last full year before age 62 (ownerBirthYear + 61) — no manual end-year entry needed in the typical case.

How it works

Federal employees covered by FERS who retire at or after their Minimum Retirement Age (MRA) but before age 62 can receive the SRS as a bridge until Social Security eligibility. The SRS is not Social Security; it is a separate FERS annuity component paid by the Office of Personnel Management (OPM). In Stratum, enter the SRS as a standalone income item of type FERS Special Retirement Supplement. The advisor sets the annual amount; the end year is auto-computed as the last full year before age 62 (using the owner's birth year) and only needs manual override for unusual cases. No earnings-test reduction is currently enforced by the system.

  1. 1. Determine MRA and SRS eligibility

    Confirm the client is a FERS employee retiring at or after their MRA (age 55-57 depending on birth year) but before age 62. Employees retiring for disability or under special provisions may not qualify. CSRS employees do not receive the SRS.

    Example: Client born 1972, MRA is 57. Plans to retire at 58. Eligible for SRS from age 58 through the year before turning 62 (Stratum's auto-default end year).

  2. 2. Enter the annual SRS amount

    Add an income item of type FERS Special Retirement Supplement. Enter the gross annual SRS from the client's OPM retirement estimate or Benefits Statement. The SRS receives no COLA adjustment. Leave indexing at 0.

    Example: OPM estimate shows an annual SRS of $14,400. Enter $14,400 with 0% indexing.

  3. 3. End year — auto-computed

    Stratum auto-defaults the SRS end year to the last full year before the owner's 62nd birthday (ownerBirthYear + 61) so the bridge income terminates at the right time without manual entry. Override only if the projection needs a different cutoff (e.g. modeling deferred retirement). The auto-default uses the owner's birth year and runs only when owner is client or co-client. If the owner is joint or the birth year is missing, the SRS falls through to the owner-death lifecycle (persists to the death year) as a visible fallback — set the end year explicitly in those cases.

    Example: Client born 1972 turns 62 in 2034. Auto-end-year = 2033 (last full year of SRS). If you'd rather model SRS through the year of the 62nd birthday, set end year explicitly to 2034.

  4. 4. Tax calculation: ordinary income, no FICA

    The full SRS amount is added to AGI as ordinary income. FICA taxes do not apply (the SRS is not wages and is not self-employment income). The SRS is not itself counted as Social Security in the provisional income calculation, but as ordinary income it appears in the 'AGI excluding SS' portion of provisional income (IRC §86) and therefore can push more of the client's actual SS benefits into the 50% or 85% taxable brackets when SS begins.

    SRS Tax = SRS Amount x Marginal Ordinary Income Tax Rate
    Example: $14,400 SRS at a 22% marginal rate produces $3,168 in additional federal tax.

Real-world context

Use cases

  • Federal employees planning early FERS retirement (before 62) who need to bridge income until Social Security begins
  • Analyzing whether the SRS plus FERS annuity covers cash-flow needs in the MRA-to-62 window
  • Roth conversion planning in the SRS years: the SRS fills ordinary income brackets and narrows conversion headroom
  • Evaluating lifetime tax cost of the SRS vs. delaying retirement to 62 when SS begins

Regulations

The FERS Special Retirement Supplement is authorized under 5 U.S.C. 8421 and administered by OPM. The earnings-test reduction is governed by 5 U.S.C. 8421a. The SRS is taxable as ordinary income under IRC 61.

Strategic considerations

Roth Conversion Window During SRS Years

The SRS fills ordinary income brackets during the MRA-to-62 period, leaving less headroom for Roth conversions. Model the SRS income first, then use the Roth Conversion strategy to evaluate how much bracket space remains.

Social Security Timing Interaction

When the SRS ends at 62, the client can begin actual Social Security but claiming at 62 triggers a permanent reduction. The SS Optimization strategy can evaluate whether delaying SS beyond 62 makes sense even though the SRS bridge is expiring.

State Tax Treatment

The SRS flows as other income, not a pension. It is not exempt under the state retirement-income exemption or the federal-pension exemption even in states that exempt FERS annuity income. Verify the client's state treatment separately.

What drives the result

SRS Annual Amount

Full amount added to AGI as ordinary income each year

Direction: increasesMagnitude: Moderate: typical SRS $8,000-$20,000/year depending on federal service history
End Year

Determines when SRS income stops. Auto-defaults to ownerBirthYear + 61 (last full year before age 62). Advisor can override for non-standard cases. The auto-default runs only for client/co-client owners with a known birth year; for joint-owned SRS or missing birth year the income falls through to the owner-death lifecycle and persists to the death year — set the end year explicitly in those cases.

Direction: mixedMagnitude: Auto-default eliminates the most common error (forgetting to terminate). Override impact depends on how far the chosen end year diverges from age 62.
Indexing Rate

The SRS is a fixed benefit and indexing should not be enabled. A non-zero rate would incorrectly grow the SRS over time.

Direction: increasesMagnitude: Should always be 0%

Assumptions

  • SRS amount is the gross annual figure from OPM without withholding modeled separately
  • The SRS is not indexed; 0% growth rate is used regardless of the inflation assumption
  • End year auto-defaults to ownerBirthYear + 61 (last full year before age 62); advisor can override
  • The SRS is treated as ordinary income for all federal and state tax calculations
  • No FICA taxes apply to the SRS

Limitations

  • The Social Security earnings test is not enforced. If the client earns wages above the annual earnings limit while receiving the SRS, OPM reduces or suspends the SRS but Stratum does not model this. Advisors with clients working before age 62 should manually reduce the SRS amount to reflect expected offsets.
  • The auto-default ends SRS in the year BEFORE the owner turns 62 (ownerBirthYear + 61). OPM in reality pays SRS through the month before the 62nd birthday, so the year of turning 62 includes a partial-year payment that Stratum's auto-default omits entirely. For clients whose 62nd birthday falls late in the year, this slightly understates total SRS income. Override the end year to ownerBirthYear + 62 if the partial-year matters.
  • The SRS flows as other income, not pension income. State retirement-income exemptions and the federal-pension exemption do not automatically apply.
  • Employees retiring under CSRS or via disability provisions may not be eligible. Stratum cannot enforce eligibility; the advisor must confirm the client qualifies.

  • Social Security Benefit Calculation — The SRS bridges income until SS begins at 62. The SS Optimization strategy can evaluate whether delaying SS beyond 62 is worthwhile even as the SRS expires.
  • Pension Income — The FERS basic annuity is entered as pension income alongside the SRS. Together they form the full FERS retirement income picture for the MRA-to-62 period.
  • Roth Conversion Tax Impact — SRS income fills lower brackets, reducing headroom for Roth conversions in the bridge years.
  • State Income Tax — The SRS is not automatically exempt under state federal-pension or retirement-income exemptions. It flows as other income. Verify state treatment.
