Open season 2025 runs from November 10, 2025 through December 8, 2025, with most federal and postal enrollments effective January 1, 2026.
Key open season dates
Mark these critical dates on your calendar so you don't miss enrollment deadlines or carrier events.
- Start date: November 10, 2025 - first day you can enroll, change, or cancel most federal health, dental, and vision plans.
- End date: December 8, 2025 - standard closing date for Federal Benefits Open Season at 11:59 pm local time for FEHB, FEDVIP, and FSAFEDS.
- PSHB extension note: Some Postal Service Health Benefits (PSHB) processing windows were extended in prior communications (example extensions to Dec. 13 reported by union guidance); verify PSHB-specific deadlines with your HR or OPM notices.
- Effective coverage: January 1, 2026 - most elections made during open season take effect on this date.
- Carrier chat days: Live carrier chat events typically occur during the first two weeks of open season (example: carrier chats on November 13, 2025 were published by some agencies).
Who should pay attention
All active federal and postal employees, eligible annuitants, and eligible family members who have or want Federal Employees Health Benefits (FEHB), Postal Service Health Benefits (PSHB), Federal Employees Dental and Vision Insurance Program (FEDVIP), or FSAFEDS should review options and act if they want to change coverage.
Retirees and those approaching retirement must pay special attention because if you retire at year-end you may need to submit SF-2809 or other documentation by December 8, 2025 to secure desired coverage effective January 1, 2026.
2025 open season at-a-glance table
| Item | Date / Window | Notes |
|---|---|---|
| Open Season Start | November 10, 2025 | Enroll, change, or cancel most FEHB/ FEDVIP/ FSAFEDS elections. |
| Open Season End | December 8, 2025 (11:59 pm) | Standard OPM deadline by local electronic system time; check PSHB exceptions. |
| PSHB Extended Window | As late as December 13, 2025 (in some guidance) | Union/agency communications noted extensions; confirm with HR/OPM. |
| Coverage Effective | January 1, 2026 | Most plan changes become operative on this date. |
| Carrier Chats | Mid-November 2025 (typical) | Live Q&A days help compare plans; example carrier day Nov. 13, 2025. |
Why these dates matter (data & context)
Open season is the single annual window when roughly 90% of non-Qualifying Life Event (QLE) enrollment changes occur, so missing the window typically means waiting a year unless you have a QLE.
Historically, the Office of Personnel Management (OPM) has announced open season windows in early fall and set effective dates at January 1 to align plan-year budgeting; the 2025 window follows that pattern.
Action checklist (step-by-step)
Follow this prioritized checklist during Open Season to protect coverage and avoid administrative delays.
- Review 2026 premiums and plan brochures for FEHB/PSHB/FEDVIP as soon as they are released.
- Confirm eligibility and dependent status; update SF-2809 or online systems if you are retiring or have status changes.
- Use online enrollment portals (FedHR Navigator, BENEFEDS, or agency HR systems) before deadlines; keep screenshots or confirmation numbers.
- Attend carrier chat days or speak with carrier reps to confirm provider networks and benefit changes.
- If you want to keep the same plan, verify automatic reenrollment rules with OPM to avoid unnecessary changes.
Common enrollment pathways
Most employees will use one of the official systems to make elections: FedHR Navigator for FEHB, BENEFEDS for FEDVIP, FSAFEDS for flexible spending, and agency HR portals for submission details.
If paper is required or preferred for retirees or special circumstances, complete SF-2809 and mail it per OPM instructions, postmarked by December 8, 2025.
Practical tips to reduce risk
Start early - completing your review in the first week avoids last-minute system slowdowns or login issues that historically spike near deadlines.
Confirm carrier participation and network changes before you switch; about 5-10% of plan networks and benefit designs change from year to year, which can materially affect out-of-pocket costs.
Representative quote
"The 2025 Federal Benefits Open Season will be held from November 10 through December 8, 2025," OPM announced when releasing plans and premiums for 2026.
Frequently asked questions
Example scenarios
If you are an active employee currently satisfied with your plan, you likely do not need to take action and will be automatically reenrolled; still, confirm there are no network or premium changes that affect your decision.
If you plan to retire December 31, 2025, you must submit appropriate health benefits election forms (SF-2809 or online equivalent) by December 8, 2025 to have coverage effective January 1, 2026.
Data snapshot and historical context
Open season windows have been stable at roughly four weeks for more than a decade; the November-December window became the norm after OPM standardized nationwide scheduling to align fiscal and plan-year cycles.
Published guidance for 2025 followed that pattern, and agencies concurrently issued plan and premium materials to help beneficiaries compare options ahead of deadlines.
Where to verify and get help
Confirm final dates and specific procedural rules with OPM's Open Season announcement pages and your agency HR office, and use BENEFEDS or FedHR Navigator for online submissions.
Contact FSAFEDS customer service or your agency benefits office if you need assistance enrolling in or managing flexible spending accounts - phone lines and chat support are typically available through the open season period.
