The Benefits Notices Employers Actually Owe
The core document
The Summary Plan Description — due to new participants within 90 days, refreshed every 5 years (10 if unchanged).
The annual set
SBC at enrollment, CHIP notice, Medicare Part D creditable-coverage letter (before Oct 15) — every year, regardless of size.
The at-hire one
The marketplace coverage notice — owed to every new employee within 14 days, benefits-eligible or not.

01

The per-participant documents

Summary Plan Description
ERISA's foundational disclosure: what the plan covers, who's eligible, how claims work — in language an average participant understands. Due within 90 days of a participant joining; restated every 5 years if amended, 10 if not. A missing SPD also means your claims procedures and limitation periods may not bind.
Summary of Benefits and Coverage
The ACA's standardized comparison card — at initial enrollment, annual renewal, and within 7 days on request. Insurers draft it; you owe the distribution, on penalty per failure.
Summary of Material Modifications
Plan changes: within 210 days after the plan year — but 60 days for material reductions in health coverage. The mid-year benefits cut has a notice deadline most employers miss.
02

The annual calendar

Before October 15
Medicare Part D creditable-coverage notice to Medicare-eligible participants — timed to the Part D enrollment window; the CMS online disclosure follows within 60 days of the plan year.
Open enrollment
SBCs for each option; CHIP premium-assistance notice (the DOL model updates twice a year); WHCRA mastectomy-rights notice; grandfathered-status notice where applicable; wellness and HIPAA notices as your plan design requires.
July 31 (calendar-year plans)
Form 5500 for plans with 100+ participants — the filing whose absence is visible to the DOL by definition. PCORI fees for self-insured plans, same date, via Form 720.
03

Event-triggered notices

At hire: the marketplace coverage notice to every employee within 14 days — eligible for your plan or not — plus the CHIP notice and any wellness disclosures with the new-hire packet. At separation or hours reduction: the COBRA election machinery, plus a certificate of the coverage end-date for the employee's marketplace special-enrollment window — sequenced in the exit-benefits guide. On FMLA leave: maintenance-of-coverage terms. On a HIPAA special-enrollment event (birth, marriage, loss of other coverage): the 30-day enrollment right your plan documents promise. Each notice is small; the pattern — event fires, notice follows — is what needs to be built once.

04

Delivery rules and automation

Delivery is its own compliance layer: DOL electronic-delivery rules cover employees whose duties include computer access (email works, with the right-to-paper statement); everyone else needs consent or mail. Intranet posting alone delivers nothing. The sustainable design treats notices as data, not memory: an annual compliance calendar owned by one named role, notice templates versioned with the plan year, delivery logged per employee per notice — because in an audit or a lawsuit, proof of delivery is the difference between a checklist and a defense. Most carriers and PEOs generate the documents; what they don't do is prove your people received them. That part stays yours.

Frequently asked questions

What's the difference between an SPD and an SBC?
The SPD is ERISA's full plain-language description of the plan — eligibility, benefits, claims procedures — due within 90 days of joining. The SBC is the ACA's standardized 4-page comparison document, due at enrollment and renewal, with a $1,000-plus per-failure penalty. The insurer typically drafts the SBC; the employer must actually distribute it.
Do small employers owe these notices too?
Most of them, yes. ERISA notices (SPD) apply to plans of any size; the CHIP, Part D and marketplace notices don't carry small-employer exemptions. The main size-based relief: plans under 100 participants generally skip the Form 5500, and under-20 groups escape federal COBRA (but usually not state continuation).
What is the Medicare Part D creditable coverage notice?
An annual letter, due before October 15, telling Medicare-eligible participants whether the plan's drug coverage is 'creditable' (at least as good as Part D). Miss it and employees who delay Part D enrollment face lifetime premium penalties — which they will attribute, correctly, to your missing letter. A parallel disclosure files with CMS.
Can we deliver everything electronically?
Under DOL rules, email delivery works for employees with work-related computer access as part of their duties; others need affirmative consent or paper. Posting on an intranet alone doesn't satisfy delivery — the notice has to be sent, with the disclosure-rights statement attached.
