Federal retiree health coverage is the single most valuable thing in the benefits package, and it is easy to lose by accident. There is no COBRA-style clock and no separate retiree plan. You either qualify to carry FEHB forward on the day your annuity starts, or you do not, and if you do not there is almost no way back in.
The comparison is stark. KFF’s employer survey found that in 2024 only 24% of large employers offering health benefits to active workers still offered anything to retirees, down from 66% in 1988. Federal retirees keep the same plan, the same network, and the same government contribution for life. Every figure below comes from OPM’s own 2026 rate charts and the FEHB Program Handbook as of September 6, 2026.
The Five-Year Rule
OPM’s FEHB Handbook sets two conditions, and you have to meet both.
First, you must be entitled to retire on an immediate annuity under a civilian federal retirement system. FERS, CSRS, the Foreign Service systems and about twenty others qualify. Social Security does not count as a retirement system for this purpose.
Second, you must have been continuously enrolled, or covered as a family member, under any FEHB plan for the five years of service immediately before your annuity begins, or for your entire period of service since your first opportunity to enroll if that is shorter than five years.
Several things widen that window. Time covered as a family member under a spouse’s FEHB enrollment counts. Time under TRICARE or CHAMPVA counts, as long as you are enrolled in FEHB on the retirement date and enrolled within 60 days of losing that coverage. Breaks in federal service are not treated as interruptions if you re-enroll within 60 days of coming back. Time with an international organization counts if you kept FEHB during it.
Two things do not count. Medicare coverage does not count toward continuous coverage. Neither does time under Temporary Continuation of Coverage as a former employee, because you were not a federal employee then.
OPM can waive the five-year requirement under 5 U.S.C. 8905(b), but only for exceptional circumstances outside your control. The handbook’s own examples of denied waivers include voluntary early retirement and simply not knowing about the rule.
You Pay the Same Premium as an Active Employee
This is the part that makes federal retiree coverage unusual, and it is written into the handbook: annuitants are entitled to the same benefits and government contribution as non-postal active employees in the same plan, and the enrollee’s share is the same.
The government’s share is the Fair Share formula from the Balanced Budget Act of 1997: the lesser of 72% of the program-wide weighted average premium, or 75% of the total premium for the plan you picked. For 2026 the monthly maximum government contribution is $703.65 for Self Only, $1,540.87 for Self Plus One, and $1,685.73 for Self and Family.
One caveat OPM flags: if your agency contributed a higher percentage than the standard formula, you lose that agency-specific sweetener at retirement. The statutory share stays.
2026 Retiree Monthly Premiums
Employees pay biweekly. Annuitants pay monthly, and the monthly column below is what actually comes out of your OPM annuity. These are 2026 enrollee shares for nationwide fee-for-service plans from OPM’s published rate chart.
| Plan and option (2026) | Self Only | Self Plus One | Self and Family |
|---|---|---|---|
| Blue Cross FEP Blue Standard | $408.02 | $890.24 | $991.60 |
| Blue Cross FEP Blue Basic | $289.83 | $691.71 | $773.20 |
| Blue Cross FEP Blue Focus | $144.76 | $311.21 | $342.28 |
| GEHA Standard | $187.95 | $404.11 | $501.47 |
| GEHA HDHP | $176.84 | $380.18 | $467.19 |
| MHBP Value | $146.89 | $348.05 | $355.00 |
| SAMBA High | $489.86 | $1,084.91 | $1,178.78 |
| Compass Rose Standard | $133.55 | $293.83 | $320.54 |
Across the whole program, OPM reports 2026 monthly weighted average total premiums of $977.28 for Self Only, $2,140.08 for Self Plus One and $2,341.30 for Self and Family. The 2026 increase averaged 10.2% overall, with the enrollee share up 12.3%. Regional HMOs are priced separately and can be cheaper or dearer than these nationwide plans, so compare both before Open Season using the FEHB premium tables.
As of September 6, 2026, no 2027 rates exist. OPM’s FAQ says new rates come out roughly a month before Open Season, generally by mid-October, and Open Season runs from the second Monday in November to the second Monday in December.
The Tax Change Nobody Warns You About
Your premium number does not change at retirement. What it costs you does.
As an employee in the Executive Branch you were automatically enrolled in premium conversion, which pays your FEHB share with pre-tax pay. OPM’s handbook states plainly that annuitants and compensationers whose premiums come out of an annuity are not eligible to participate in premium conversion.
Put dollars on it. Blue Cross Standard Option Self Only costs $408.02 a month in 2026, or $4,896.24 a year. As an employee in the 22% federal bracket, premium conversion sheltered that from federal income tax and from the 7.65% Social Security and Medicare payroll tax, worth roughly $1,450 a year in combined savings. In retirement, the same $4,896.24 comes out of after-tax annuity income and the shelter is gone.
There is a partial offset. Health insurance premiums are a qualifying medical expense if you itemize and your total medical costs clear 7.5% of adjusted gross income, which more retirees hit than workers do. See the medical expense tax deduction for what actually counts.
How Premiums Come Out of Your Annuity
Your share is withheld from your monthly annuity payment. If the annuity is too small to cover it, you have two options: move to a lower-cost plan whose enrollee share fits, or pay the retirement system directly.
Direct payment is a one-way door. The handbook says an annuitant who elects direct payment keeps paying directly for the length of the enrollment, even if the annuity later grows enough to cover it.
Miss a direct payment and the timeline is short. The retirement system must notify you in writing that payment is due within 15 days (45 days if you live overseas). If you do not pay, enrollment terminates 60 days after the notice, retroactive to the end of the last period you paid for, and an annuitant terminated for nonpayment generally may not re-enroll.
What Happens to Your Spouse
Survivor coverage depends on two decisions you make before you die, not after.
For a surviving family member to keep the enrollment, you must have been enrolled in Self Plus One or Self and Family at the time of death, and at least one family member must be entitled to a survivor annuity. Meet both and coverage continues automatically at the same premium and the same government contribution, deducted from the survivor annuity. If you are the last covered person, the retirement system converts the enrollment to Self Only.
Under FERS, a surviving spouse entitled to the basic employee death benefit, or surviving children whose benefits are offset by Social Security, can keep the enrollment by paying OPM directly. If the survivor annuity is too small to cover the premium, the same options apply: a cheaper plan, or direct payment.
The failure mode is dropping to Self Only in your seventies to save money, or waiving the survivor annuity to get a larger monthly check. Either one ends your spouse’s coverage the day you die.
Timing Traps Around Your Retirement Date
Cancelling is permanent. An annuitant who cancels FEHB can never re-enroll. Suspending is different and reversible: you may suspend to use a Medicare Advantage plan, Medicaid, TRICARE, TRICARE For Life, CHAMPVA or the Peace Corps, and re-enroll at a later Open Season or immediately if you involuntarily lose the other coverage.
MRA + 10 with a postponed annuity. If you separate under FERS Minimum Retirement Age + 10 and postpone the annuity, your FEHB enrollment terminates at separation. You get 31 days of free extended coverage plus a right to TCC or conversion, and you can resume FEHB on the date you choose for the annuity to start.
FEDVIP has no five-year rule. Dental and vision coverage continues into retirement no matter how long you have had it, but retirement is not a qualifying life event, so you cannot add or change it just because you are retiring. Deductions can take one to three months to shift from payroll to annuity while you are on interim pay, and BENEFEDS may direct-bill you or double-deduct later to catch up.
FSAFEDS ends. Your flexible spending account terminates when you retire, and annuitants cannot enroll. If you are carrying a balance, spend it before your separation date. See FSAFEDS.
Open Season is your only routine lever. Retirement itself does not let you change health plans. Time a plan switch to the Open Season before you go, or wait for the next one.
Your Choices at 65
Turning 65 does not change your FEHB premium. OPM is explicit that enrolling in Medicare neither reduces nor increases what you pay for FEHB. What changes is whether it is worth adding the 2026 Medicare Part B premium of $202.90 a month on top, and whether a different FEHB option would treat you better once Medicare is primary. That decision has its own guide: FEHB and Medicare Part B.
Postal retirees are on a different track entirely. Postal employees and annuitants moved to the Postal Service Health Benefits Program in 2025, with its own premiums and, for most Medicare-eligible annuitants, a Part B enrollment requirement.
If you are leaving federal service before you are eligible for an immediate annuity, none of this applies and the math is much worse. Start with health insurance for early retirees instead.
