Carrier booklets don’t meet federal documentation rules, and some notice deadlines start the day a plan change is adopted
Open enrollment produces a lot of paper: new carrier booklets, updated benefit summaries, revised certificates of coverage. What it doesn’t produce is the plan document an employer itself is expected to keep.
As employers lock in 2027 renewals ahead of the Jan. 1 plan year, that gap matters. The Employee Retirement Income Security Act (ERISA) requires every employee benefit plan to be established and maintained under a written plan document, according to a National Association of Benefits and Insurance Professionals (NABIP) compliance presentation. The same presentation suggests a wrap document to supplement insurance paperwork and supply missing ERISA provisions.
Who owns the paperwork
The plan sponsor must furnish employees with a plan document and a summary plan description (SPD), though a third-party administrator often helps, Benefitfocus said in its ERISA compliance guide. Outsourcing the administration doesn’t hand off the obligation. HRD America reported that claims data access belongs on the negotiating list when vendor contracts are set or renewed, and document duties belong there too.
When a renewal change triggers an update
Most plan changes require a summary of material modifications (SMM), or an updated SPD, within 210 days after the end of the plan year in which the change was adopted. A material reduction in covered services or benefits under a group health plan shortens that to 60 days after adoption, under the Department of Labor’s regulation at 29 CFR §2520.104b-3. An updated SPD satisfies the SMM requirement, according to the department’s reporting and disclosure guide.
The regulation defines a material reduction as a change the average participant would consider important, and the National Law Review noted that increases in premiums, deductibles, coinsurance or copayments can qualify. A plan can skip the separate 60-day notice if it describes material reductions in a communication sent at least every 90 days.
Take an employer that adopts a higher deductible on Nov. 15. It has until Jan. 14 to notify participants, not 210 days after the plan year ends.
What a missed request can cost
Participants can ask in writing for the plan document or SPD, and the administrator has 30 days to provide it, according to the Department of Labor. Under ERISA section 502(c)(1), a court can penalize an administrator up to $110 a day for missing that window. The U.S. Court of Appeals for the Second Circuit has noted that such awards are discretionary.
Plans without current documents face other exposure. Employers missing plan documents and SPDs may face Department of Labor penalties and fines, USI said, and the NABIP presentation notes the department has broad authority to audit ERISA compliance. Benefit plans are also drawing lawsuits, and HRD America reported that voluntary benefits lawsuits are turning employer Form 5500 data into evidence.
Another deadline in the same window
Plans must submit their gag clause prohibition attestation to the Centers for Medicare & Medicaid Services (CMS) by Dec. 31, according to Lockton. A carrier’s filing can cover insured plans, HUB International said, but employers with self-insured plans must complete their own.
A 2026 benchmarking report found employers prioritizing governance and precision over new benefits programs, HRD America reported. Documents are where that discipline shows up first.
The carrier’s renewal packet won’t include the plan document. Employers have to produce it themselves, and for some changes the notice clock is already running.
