For California employers, open enrollment is the most important benefits moment of the year. It affects costs, compliance, and employee satisfaction for the next twelve months. Because rules and market conditions evolve, treating open enrollment as a simple renewal can be a big mistake. It can lead to missed savings, confusion, and compliance risks. This guide breaks down what to expect this season and how to run a smooth, high-engagement open enrollment that fits California’s landscape.
The News Shaping Open Enrollment This Year
Two developments should be on every HR and finance agenda. First, Covered California and national outlets are warning that marketplace premiums could rise in 2026. Because enhanced federal subsidies expire at the end of 2025, employee contribution pressure could rise during open enrollment. Especially, if Congress doesn’t act. Covered California has already alerted members that financial help may shrink in 2026, even though 2025 premiums remain stable for many enrollees. Covered California National reporting similarly notes potential premium increases and political debate about extending those subsidies.
Second, federal rule-making is altering Marketplace enrollment mechanics leading into the 2026 plan year. A recently finalized federal rule standardizes parts of the enrollment process and changes several special enrollment policies, which may reduce flexibility for some households and increase the importance of the main open enrollment window.
Open Enrollment Basics for California Employers
At its core, open enrollment is the defined period when employees can enroll in, drop, or change health plans and other benefits without a qualifying life event. It’s also the moment to refresh dependent information, update beneficiary designations, and re-elect accounts such as Health FSAs. For state employees, CalHR has confirmed the 2025 Open Enrollment window runs September 15 through October 10, with elections effective January 1, 2026, which is a useful duling reference even if you are in the private sector.
If you sponsor a group plan, you control your own open enrollment dates, but you must meet carrier deadlines and provide required disclosures on time. The more complex your workforce, the earlier you should begin.
California-specific Updates to Bring Into Open Enrollment
Several California policy changes intersect with benefits planning and should appear in your open enrollment materials and manager training. A notable 2025 change under AB 2123 prohibits employers from requiring employees to use accrued vacation before accessing state Paid Family Leave. Your handbook and enrollment communications should reflect this, along with how voluntary disability or leave-related benefits coordinate with PFL.
You should also message IRS updates that affect employee elections. For example, the health FSA salary reduction limit for 2025 is $3,300, and plans that permit carryover allow up to $660 to roll from 2024 into 2025. Reminding employees about these limits during open enrollment improves participation and reduces surprises.
Finally, if you employ workers who buy individual coverage through Covered California, watch the subsidy discussion and plan your communications for the November 1 through January 15 individual market open enrollment window. Employees weighing individual policies will need timely guidance if subsidies change.

Communicating Value During Open Enrollment
A strong open enrollment is as much about education as it is about forms. Use decision aids that model real scenarios, such as a routine year versus a surgery year, so employees understand deductible and out-of-pocket interactions. Additionally, you can offer micro-sessions on pharmacy tiers, telehealth, mental health access, and how to find in-network providers.
If you want to go even further, don’t forget voluntary benefits. Dental, vision, hospital indemnity, and accident plans, since these can cushion out-of-pocket risk for families, and they often cost your company little because employees can purchase through payroll deduction. Educate employees on how these pair with required California programs, like SDI and PFL, to close income gaps during leave.
Understanding benefits terminology also plays a major role in employee confidence. To help your workforce navigate enrollment more easily, download our Employee Benefits Acronym Guide, a simple tool that explains the most common terms in clear, plain language. Resources like this reduce confusion, improve benefits literacy, and make employees more comfortable comparing health plans.
Avoid the Most Common Open Enrollment Pitfalls
Late or confusing notices: If plan changes are not explained in plain language, employees make default choices that drive higher claims and dissatisfaction.
Under-communicating cost changes: Given 2026 subsidy uncertainty and national premium headlines, be direct about how payroll deductions may be affected and outline ways to save.
Ignoring compliance edges: Update FSA, HSA, COBRA, and leave references. Verify your eligibility rules align with California law and carrier contracts.
Skipping post-enrollment validation: Reconcile carrier confirmations against your HRIS, because certainly, catching an error in January is far better than in March.
How a Broker Improves Open Enrollment Outcomes
A California-based advisor can benchmark plans, negotiate renewals, align your open enrollment calendar with vendor deadlines, and build employee-friendly communications. Just as important, a broker can translate evolving federal rules for the individual marketplaces and Covered California into clear talking points for your workforce.
Final Thoughts
This year’s open enrollment happens against a moving backdrop of federal rule changes and possible subsidy shifts that could affect 2026 affordability. With a structured timeline, clear communication, and California-specific updates in your materials, you can help employees choose wisely and keep your benefits budget predictable.
