Reemployed Annuitant: What Happens When a Federal Retiree Returns to Federal Service

Federal agencies routinely bring retired employees back — to fill critical skill gaps, cover vacancies during hiring freezes, or respond to agency reorganizations. If you're a FERS or CSRS retiree being asked to return, the rules are complex and the financial tradeoffs are substantial. Here's exactly what happens to your annuity, your FERS supplement, your TSP, and your health insurance when you go back.

The default rule: salary offset

When a federal retiree returns to federal service as a civilian employee, they become a reemployed annuitant. By default, the retiree keeps receiving their annuity and earns a salary from the new position — but the two overlap. The law requires the salary to be offset by the gross annuity amount, so the net paycheck is reduced.1

The formula:

Net salary = Position rate of pay − Gross annuity (basic annuity + FERS supplement)

The "gross annuity" that offsets salary includes both the basic FERS or CSRS pension payment and, if you're under age 62 and still receiving it, the FERS annuity supplement. The annuity payment from OPM continues uninterrupted during reemployment — what changes is that your employment pay is reduced by that amount.

Salary offset example

ComponentAmount/year
GS-14, Step 8 (DC locality) — position rate$145,000
FERS basic annuity (30 years × 1% × $140K high-3)$42,000
FERS supplement (age 60, under MRA+10 supplement eligibility)$21,600
Gross annuity (offset amount)$63,600
Net employment salary (take-home from agency)$81,400
Total income (net salary + OPM annuity)$145,000

The retiree's total income equals the position rate — not the position rate plus the annuity. The offset eliminates the "double dip" economically. What the retiree gets is the same as if they were a current employee at that grade level, but paid via two separate streams.

Important: The net salary ($81,400 in this example) is subject to federal income tax as wages. The OPM annuity is also taxable (under the Simplified Method). So the tax picture is messier than it looks — more income sources, potentially higher effective rate.

The exception: dual compensation waiver

Agencies can apply to OPM (or use their own statutory authority) for a dual compensation waiver, which allows a reemployed annuitant to receive both the full annuity and the full position salary simultaneously — with no offset.2

Agencies most commonly seek waivers for:

What changes with a waiver

Without waiver (default offset)With dual compensation waiver
Net employment salaryPosition rate − annuityFull position rate
Total incomeEquivalent to position ratePosition rate + full annuity
New FERS/CSRS retirement benefit accrualYes — counts toward supplemental or redetermined annuityNo — no new benefit accrual
TSP contribution eligibilityYes — employee and agency contributionsNo — not eligible
RIF protectionsBased on appointment typeNone — at-will employment
FERS retirement contributions deductedYes (from net salary)No

The waiver is financially superior in total income, but comes at the cost of no additional retirement benefit accrual, no TSP access, and no job security. Reemployed annuitants with waivers can be separated at any time without RIF procedures.

Building new retirement benefits without a waiver

If you return without a waiver and contribute FERS retirement deductions from your reduced salary, the new period of service counts toward additional retirement benefits under 5 CFR Part 837:

Supplemental annuity (1–4 years of new service)

If you complete at least one year of continuous full-time service (or the part-time equivalent), you become entitled to a supplemental annuity on separation. This is a separate, additional annuity computed on the new period of service:1

Redetermined annuity (5+ years of new service)

If you accumulate at least five years of additional service, you may elect a redetermined annuity instead. This replaces — not supplements — your original annuity. It recalculates your entire career as if you had served continuously:1

The redetermined annuity is typically the better outcome for anyone returning at a higher grade level for 5+ years — because the new high-3 at the higher GS grade is applied retroactively to the entire career.

TSP when reemployed

Whether you can contribute to TSP depends on whether you have a waiver:

Your existing TSP balance is unaffected in either case. You don't need to touch it, roll it over, or make any changes simply because you returned to federal service. The balance remains invested and continues to grow.

FEHB (health insurance) during reemployment

If you were enrolled in FEHB as an annuitant (premiums paid from your OPM annuity check), reemployment transfers that enrollment to your new employing agency. The key changes:4

Importantly, FEHB enrollment during reemployment continues to count toward the 5-year FEHB requirement needed to carry coverage into retirement. If a retiree returned before completing 5 years and then has a second separation, the combined pre-retirement + reemployment FEHB time counts.

FEGLI (life insurance) during reemployment

Federal life insurance under FEGLI is restructured when you return:

FERS supplement and the earnings test during reemployment

This is where reemployment creates a financial surprise most annuitants don't anticipate. The FERS annuity supplement earnings test applies to W-2 wages — including the net salary you earn as a reemployed annuitant. The 2026 exempt amount is $24,480. For every $2 you earn above that threshold, your supplement is reduced by $1.5

In practice: virtually any federal salary will exceed $24,480, which means the FERS supplement is reduced to zero during any year you are reemployed with meaningful federal salary.

Supplement earnings test with salary offset

Even under the default salary offset arrangement, your net W-2 wages (the reduced salary) count as earnings for the supplement test. Using the earlier example:

OPM administers this through an annual earnings survey (Form RI 92-22, sent each spring). Supplement payments continue monthly during the year, but OPM adjusts the following year's payments to recover any overpaid amount. Reemployed annuitants receiving the FERS supplement should set aside a portion of supplement payments to cover the year-end adjustment.

The supplement naturally ends at age 62 regardless, so this only affects annuitants who are between their Minimum Retirement Age and 62.

FERS supplement rules: supplement continues if you stopped working before reaching MRA

One nuance: the FERS supplement doesn't start just from being a retiree — it requires having retired under an immediate retirement and reaching MRA (if on a postponed annuity under MRA+10, the supplement never pays). Under most circumstances, a reemployed annuitant receiving the supplement was already at or past their MRA before the reemployment.

RIF protections for reemployed annuitants

Reemployed annuitants under a dual compensation waiver are explicitly excluded from Reduction in Force protections under 5 CFR Part 351. They can be separated at any time, for any reason, without RIF procedures. This is one of the key tradeoffs accepting a waiver position:

Social Security while reemployed

As a reemployed annuitant earning wages, you pay Social Security and Medicare taxes on your employment income — just like any employee. This may add quarters of coverage toward SS eligibility if you weren't already fully insured (40 quarters). It may also increase your projected SS benefit if the new earnings exceed any of your prior 35 highest earnings years in the benefit computation.

Worked example: GS-15 cybersecurity specialist returns after 2 years

Setup: A GS-15 IT specialist retired at age 60 with 32 years of federal service. They receive $52,800/year in basic FERS annuity and a $22,800/year FERS supplement ($75,600 total gross annuity). Their agency asks them to return as a GS-15 ($155,000 position rate) for a 2-year cybersecurity modernization project — without a dual compensation waiver.

Option A: Return with salary offset (no waiver)

Option B: Return with dual compensation waiver

Which option wins?

Option B (waiver) provides ~$52,800 more per year in cash. Option A (no waiver) gives $3,100/year more in permanent pension, TSP contribution access (potentially $60K–$70K in additional retirement savings over two years with matching), and job protections. For a two-year engagement, the waiver wins financially for the employee — but the permanent retirement benefit gain under the offset option has long-term value beyond the two years.

Common questions

Does my original retirement date change when I return?
No. Your original federal retirement date is preserved for all purposes. The new period of service creates a supplemental or redetermined annuity — it doesn't restart your retirement clock.
What happens to the FERS supplement when I turn 62 during reemployment?
The FERS supplement stops at age 62 regardless of employment status. Your basic annuity continues. This is separate from the earnings test reduction.
Can I take TSP distributions while reemployed?
Generally, no — if you are reemployed in a position that brings you back under FERS/CSRS coverage, in-service withdrawal rules apply (typically no in-service withdrawals from TSP before 59½ except for financial hardship). If you are over 59½, you may be eligible for age-based in-service withdrawals. Consult the TSP Service Office for your specific situation.
Does reemployment affect my FERS COLA?
No. Annual cost-of-living adjustments to your basic annuity continue during reemployment. The FERS diet COLA applies as normal — zero before age 62, then the capped formula after. Reemployment does not suspend or delay COLAs.
What if I want to work as a federal contractor instead?
Contractor employment with a private firm that holds a federal contract is not the same as reemployment in federal service — there is no salary offset, no annuity implications from OPM's perspective, and no FEHB transfer. The only impact is on the FERS supplement earnings test if your contractor wages (W-2 income) exceed $24,480. Many retirees prefer contractor roles for this reason.
How long can I stay as a reemployed annuitant?
There is no federal time limit on reemployed annuitant status. Some temporary appointment authorities have time limits (1-4 year terms), but the reemployed annuitant status itself doesn't expire. However, waiver authorities granted by OPM often specify a time-limited period.
