Open Season 2026 runs November 10-December 8, 2025 and during that window federal employees and retirees can enroll in or change FEHB, FEDVIP, and FSAFEDS elections for the 2026 benefit year; FEHB changes take effect January 11, 2026 (pay period 1) while FEDVIP and FSAFEDS elections generally become effective January 1, 2026.
Key dates and deadlines
Open Season begins on November 10, 2025 and ends on December 8, 2025 at 11:59 p.m. Eastern for most programs; Postal Service enrollees may have a different cut-off date in some cases.
- Open Season window: November 10 - December 8, 2025.
- FEHB changes effective: January 11, 2026 (first pay period of 2026).
- FEDVIP & FSAFEDS effective: January 1, 2026, unless otherwise noted by plan.
- FSA claims filing deadline: typically April 30, 2027 for the 2026 plan year (verify with FSAFEDS).
What benefits you can change
During Open Season you can enroll in, cancel, or change coverage in the major federal benefits programs: FEHB (health), FEDVIP (dental & vision), and FSAFEDS (flexible spending).
- FEHB: change plans, change enrollment type (Self Only, Self + One, Self & Family), or enroll for the first time.
- FEDVIP: elect or change supplemental dental and vision coverage; enrollments generally continue year-to-year but changes require action during Open Season.
- FSAFEDS: you must re-enroll each year to participate; dependent care and health care FSAs have separate limits and carryover rules.
Practical steps to prepare
Before you log in, gather documentation and compare costs: your 2025 Explanation of Benefits, recent prescription drug costs, provider networks, and the 2026 plan brochures are essential to make an informed choice.
- Use plan comparison tools to estimate premiums and out-of-pocket costs for 2026.
- Check if your current provider remains in-network under proposed 2026 plan options.
- Re-enroll in FSAFEDS if you want a health or dependent-care FSA; these do not automatically continue.
Premiums, participation, and enrollment systems
Most federal agencies direct employees to their electronic enrollment system or Employee Personal Page (EPP) for FEHB transactions, while FEDVIP uses BENEFEDS and FSAFEDS enrollments use the FSAFEDS portal; if you do nothing, current FEHB and FEDVIP coverage typically continues automatically but FSA requires re-enrollment.
| Program | Action required | Effective date | Common deadline |
|---|---|---|---|
| FEHB (health) | Enroll/change/cancel via EPP or agency system | January 11, 2026 (Pay Period 1) | Dec 8, 2025, 11:59 p.m. ET |
| FEDVIP (dental & vision) | Enroll/change via BENEFEDS | January 1, 2026 | Dec 8, 2025, 11:59 p.m. ET |
| FSAFEDS (flexible spend) | Must re-enroll each year via FSAFEDS | January 1, 2026 | Dec 8, 2025, 11:59 p.m. ET |
Cost and plan counts (context & notable changes)
For 2026 carriers and premiums saw modest reshuffling: industry reporting indicated roughly 132 FEHB plan options available for 2026 after several plan consolidations and six plans discontinued, reflecting network and rate changes across regions.
- Estimated number of FEHB plans in 2026: 132 plan options nationwide.
- Typical FEHB premium changes in recent years have ranged from 3%-8% on average, but local employer/plan variance is common.
- FSA carryover and maximums: sample figures used in 2026 guidance included a $680 carryover cap for Health Care FSA and a $3,400 annual election maximum (confirm exact limits with FSAFEDS).
Common scenarios and their impacts
If you switch from Self Only to Self & Family or Self + One, expect a higher payroll premium contribution; switching to a high-deductible health plan may lower premiums but increase out-of-pocket risk if you expect significant medical care in 2026.
- Staying put: no action needed for FEHB or FEDVIP-coverage generally continues automatically.
- Switching plans: complete the online transaction by December 8 to ensure your new FEHB plan is active in January 2026.
- Electing FSA: re-enroll and estimate contributions carefully to avoid forfeiture; Health Care FSA carryover is limited and dependent on plan rules.
Quotes and historical context
Historically, Open Season has run in early November through early December since the modern FEHB structure expanded in the 1960s; executive guidance and OPM notices set the exact annual dates and program rules.
"Open Season is the single annual opportunity for most federal employees to make benefit elections without a qualifying life event," said a benefits official in recent Open Season guidance, underscoring the importance of reviewing plan changes and premiums before the December deadline.
Agency-specific notes and exceptions
Certain agencies and postal employees may have slight differences for their enrollment systems or deadlines-for example, Postal Service participants sometimes have an extended enrollment window or distinct cut-off rules; always check your agency HR notice or the BENEFEDS/agency portal for precise instructions.
- Postal Service Health Benefits may use a separate enrollment timeline in some years; confirm with USPS or OPM notices.
- Employees affected by a shutdown or other administrative disruption should follow agency contingency instructions and contact their HR office.
- Retirees and survivors have parallel Open Season rules but must use the retiree-specific web channels or contact retirement services for transactions.
Filing claims and carryover rules
FSAFEDS and HCFSA carryover/grace provisions are specific: typical guidance for 2026 noted a $680 carryover from 2025 to 2026 for eligible health FSAs if re-enrolled, and a claims filing deadline around April 30, 2027 to submit 2026 plan-year claims; check FSAFEDS for any final rule changes.
Checklist: what to do this Open Season
Use this compact checklist to ensure you don't miss critical steps before the December 8 deadline.
- Collect 2025 usage data: prescriptions, specialists, and major expected services for 2026.
- Run premium and out-of-pocket comparisons using the OPM plan tools and carrier brochures.
- Re-enroll in FSAFEDS if you need a Health or Dependent Care FSA for 2026.
- Make FEHB and FEDVIP elections through your agency enrollment system or BENEFEDS before the deadline.
- Save confirmation receipts/screenshots of final transactions and note effective dates.
Where to get help
Your servicing Human Resources office is the primary local resource for questions about timing and systems, while BENEFEDS and FSAFEDS offer call centers for program-specific questions; use official agency contact points rather than third-party sites for binding guidance.
- Contact your local HR office for agency-specific procedures and confirmation of effective dates.
- Use BENEFEDS for dental & vision support and FSAFEDS for flexible spending assistance.
- Check OPM's Open Season web pages for official plan comparison tools and premium tables.
Key concerns and solutions for Federal Employee Benefits Open Season 2026 Details
How do I re-enroll in FSAFEDS?
Go to the FSAFEDS enrollment portal during Open Season, select your annual election (health care or dependent care) and confirm your payroll deduction amount; re-enrollment is mandatory each year for Health and Dependent Care FSAs.
What happens if I miss the Open Season deadline?
Missing the December deadline usually means you cannot change FEHB or FEDVIP coverage until the next Open Season unless you experience a qualifying life event (marriage, birth, loss of other coverage); FSA enrollment cannot be added later except under strict qualifying events.
Will my current plan automatically continue?
Yes - for FEHB and most FEDVIP enrollments, if you take no action your current coverage generally continues into the next plan year; however, FSAFEDS requires active re-enrollment each year to participate.
Where can I get official plan documents?
Official plan brochures, premium tables, and plan comparison tools are published by the Office of Personnel Management and by individual carriers-visit your agency HR page, OPM's Open Season pages, BENEFEDS, and FSAFEDS for authoritative documents and calculators.
