The question comes up often, and the answer is short. Federal employees, married or not, cannot directly transfer unused sick leave from one employee’s balance to the other’s. The sick-leave balance that converts to retirement service credit belongs to the employee who earned it, and it stays with that employee through retirement.

The interesting part of the question is not the answer. The interesting part is what can be done with sick leave when both spouses are federal employees, and what other decisions the question is often a proxy for.

The rule, plainly.

Unused sick leave is a non-shared employee benefit. Each federal employee accumulates their own sick-leave balance under their own agency’s leave system, and that balance is converted to retirement service credit on the day thatemployee separates. There is no mechanism under OPM regulations to transfer hours from one employee’s balance to another’s, whether the two employees are spouses, family members, or unrelated.

This is true for FERS, CSRS, and the FERS-Offset systems. It is true for general-schedule employees, special category employees, and SES members. The rule is structural, not case-specific.

What is actually transferable.

Two federal employees who are married cannot share sick leave, but they can share a number of other things that materially affect retirement. The list of shared decisions is long, and most couples I work with underestimate how many of them there are.

  • FEHB enrollment.Either spouse can carry the family FEHB enrollment. If one spouse retires first and the other continues working, the working spouse can remain the FEHB enrollee. If the working spouse leaves federal service before retirement eligibility, the retiring spouse’s FEHB can be the family’s only federal coverage — subject to the standard five-year continuous enrollment rule.
  • FEHB and the survivor annuity.The survivor annuity election made at the first spouse’s retirement controls whether the second spouse retains FEHB after the first spouse’s death. This is the single most consequential decision the couple makes together, and it is the one most often made without either spouse fully understanding it.
  • FEGLI coverage.Federal Employees’ Group Life Insurance can be carried into retirement with no reduction (under basic, with some limitations) only if the employee has been continuously enrolled for the five years immediately preceding retirement. Either spouse’s retirement date can affect the other’s decision.
  • TSP beneficiary designations.TSP beneficiary elections are not shared between spouses, but the default rules apply — and the spouse generally is the default beneficiary for married employees, regardless of what the form says. The form does need to be on file, and the order of beneficiaries matters.
  • Social Security claiming.Spouses coordinate Social Security claiming decisions based on their respective earnings records. The higher earner’s claiming age generally sets the floor for the couple’s combined benefit, and the spousal benefit calculation uses the higher earner’s primary insurance amount.
  • The FERS supplement.If one spouse retires under MRA and receives the supplement, the supplement calculation is based on that spouse’s own earnings record. It does not transfer to the other spouse during the spouse’s lifetime, but the timing of the first spouse’s retirement can shift the household’s combined income picture meaningfully.

The one place sick leave does move between households.

There is one scenario in which sick leave has a kind of “household” effect, and it is worth understanding because it is the one place the question is partially right.

When a federal employee dies in service, their surviving spouse may be eligible for a lump-sum death benefit, and the deceased employee’s accrued unused sick leave may be credited in the calculation of any survivor annuity. The sick leave is paid out through the survivor benefit, not transferred into the surviving spouse’s own retirement calculation. It is the only circumstance in which sick leave has a direct dollar impact on someone other than the employee who earned it.

The proxy questions hiding inside the real question.

When a federal employee asks whether sick leave can be transferred to a spouse, they are often trying to solve a larger problem. The actual question is usually one of the following, and each is worth its own conversation:

1. “My spouse is retiring before me. Can I add their sick-leave service to my own retirement date?”

No. Your retirement date is determined by your own service and your own age, and your own sick leave is the only sick leave that converts to your annuity. A spouse’s retirement date does not change your own.

2. “If I retire with a low sick-leave balance, can I borrow hours from my spouse?”

No. The balance on the day you separate is yours alone. Borrowing hours from another federal employee is not a permitted transaction.

3. “If my spouse retires first, will their sick-leave service raise our combined household income?”

Indirectly, yes. A larger annuity for the first retiring spouse produces a larger combined household income, and a larger foundation for the survivor benefit if the second spouse survives the first. The sick-leave conversion is part of that annuity, but it is a piece of the larger arithmetic, not a separate lever.

4. “If we both work, are we better off if one of us quits early to use up sick leave before retirement?”

Almost never. Sick leave used during federal service does not add to retirement service credit. Sick leave unused at separation does. The optimal move, for retirement purposes, is usually to preserve the sick-leave balance through retirement, not to use it up beforehand.

What to model when both spouses are federal employees.

The real retirement conversation for a two-federal-employee household is wider than sick leave. A few things that should be on the table:

  • Who retires first, and when.The two retirement dates drive the survivor election, the FEHB continuity, the FEGLI continuity, and the household’s combined income curve.
  • Whether to elect a survivor annuity at the first retirement. This is the irreversible decision that controls whether the second spouse retains FEHB and how the first annuity continues after the first death.
  • The five-year FEHB and FEGBI rules. The five-year continuous enrollment rules are unforgiving, and a gap of one day at the wrong moment can lose FEHB or full FEGLI coverage for the rest of the second spouse’s life.
  • Social Security coordination.The two earnings records interact through the spousal benefit, and the timing of one spouse’s claiming decision can shift the household’s combined Social Security income by tens of thousands of dollars over a 25- or 30-year retirement.
  • TSP beneficiary designations. The forms need to be on file, reviewed, and kept current. The default is rarely what the couple would choose consciously.

The list is long. The conversation is worth having while both spouses are still employed, because the decisions that cannot be undone are easier to identify before they are made.

The plain summary.

Sick leave cannot be transferred between federal employees, including spouses. Each employee’s sick-leave balance is their own, and it converts to service credit on the day they separate. The “household” effect of sick leave for two-federal-employee couples is real, but it shows up in the survivor benefit calculation, not in the transfer of hours.

The conversation that the question is a proxy for is the more important one. Two-federal-employee couples have a longer list of shared retirement decisions than most realize, and the list deserves a longer conversation than most have.
