Employer Notification Obligations and Timelines

COBRA's notification framework places specific, time-bound obligations on employers and plan administrators, and missing any deadline exposes the plan sponsor to statutory excise taxes and civil penalties. This page details what employers must communicate, to whom, and within what timeframes under the Consolidated Omnibus Budget Reconciliation Act of 1985 as codified in Internal Revenue Code §4980B and ERISA §§601–608. Understanding these obligations is foundational to any COBRA compliance program — a full overview of the regulatory framework is available at Regulatory Context for COBRA Administration.

Definition and Scope

Employer notification obligations under COBRA refer to the structured set of written communications that group health plan sponsors must deliver when certain qualifying events occur or when employees first enroll in a covered plan. The Department of Labor (DOL) administers the notification provisions under ERISA, while the IRS enforces penalty provisions under IRC §4980B (IRS, IRC §4980B).

These obligations apply to private-sector employers with 20 or more employees on at least 50 percent of typical business days in the prior calendar year (DOL COBRA Overview). Federal government plans, church plans, and employers below that workforce threshold are generally exempt from federal COBRA, though state mini-COBRA laws may impose parallel obligations on smaller employers.

Two primary notification duties fall on the employer specifically:

Initial Notice — delivered when an employee (and covered spouse or dependent) first becomes covered under the group health plan.
Qualifying Event Notice to the Plan Administrator — delivered within a defined window after a qualifying event occurs.

The plan administrator then carries responsibility for sending the Election Notice to qualified beneficiaries, but the qualifying event notice that triggers that downstream communication originates with the employer.

How It Works

The notification chain under COBRA moves in a fixed sequence. Employers hold responsibility for two links in that chain.

Step 1 — Initial Notice (General Notice)
Within 90 days of the date a covered employee or dependent first becomes enrolled in the group health plan, the plan administrator must furnish a written General Notice describing COBRA rights (29 CFR §2590.606-1). In practice, the employer or its designated plan administrator is responsible for this delivery. The DOL publishes a Model Initial COBRA Notice (DOL Model Notices) that satisfies this requirement when properly completed.

Step 2 — Employer's Qualifying Event Notice to the Plan Administrator
When a qualifying event occurs that is within the employer's direct knowledge — specifically, termination of employment, reduction in hours, death of the covered employee, Medicare entitlement, or commencement of a bankruptcy proceeding — the employer must notify the plan administrator within 30 days of the event (ERISA §606(a)(2)).

When the employer and the plan administrator are the same entity (common in self-administered plans), this step is internal, but the 30-day clock still controls downstream deadlines.

Step 3 — Plan Administrator's Election Notice
Once notified of a qualifying event, the plan administrator has 14 days to furnish the Election Notice to each qualified beneficiary. The beneficiary then has 60 days to elect continuation coverage.

The combined maximum window from qualifying event to Election Notice delivery is therefore 44 days when the employer uses the full 30-day qualifying event notice period plus the administrator's 14-day response period.

Common Scenarios

Termination or Reduction in Hours
The employer learns of the qualifying event directly — whether voluntary resignation, involuntary termination, or a scheduled reduction in hours. The 30-day employer notice window begins on the date the coverage loss occurs (or would occur), not the date the employer decides to act. More detail on these event types appears at /regulatory-context-for-cobra-administration.

Employee Death
Death of a covered employee triggers COBRA rights for surviving spouses and dependent children. The employer holds the notification obligation and must transmit notice to the plan administrator within 30 days of the date of death.

Medicare Entitlement
When a covered employee becomes entitled to Medicare, that entitlement is a qualifying event for covered spouses and dependents (though not for the employee in most circumstances). The employer's 30-day notice window applies here as well, beginning on the date of Medicare entitlement.

Employee-Initiated Events (Divorce, Dependent Status Loss)
For qualifying events that the employer does not directly observe — divorce, legal separation, or a dependent child aging out of coverage — ERISA §606(a)(3) shifts the notice obligation to the covered employee or dependent. The employee or dependent has 30 days to notify the plan administrator. Employers satisfy their obligation here by maintaining a written notification procedure and communicating it in the Initial Notice and Summary Plan Description.

The contrast between employer-triggered and employee-triggered events is among the most operationally significant distinctions in COBRA administration, directly affecting who bears liability for a late election notice.

Decision Boundaries

Determining which party holds the notification obligation and which deadline governs requires classifying the qualifying event against three binary criteria:

Was the event within the employer's direct knowledge?
Yes (termination, reduction in hours, death, Medicare entitlement, bankruptcy) → Employer holds the 30-day notice obligation to the plan administrator.
No (divorce, legal separation, loss of dependent status) → Covered employee or dependent holds the 30-day notice obligation directly to the plan administrator.
Are the employer and plan administrator the same entity?
Yes → The 30-day and 14-day windows effectively collapse into a single 44-day maximum window measured from the qualifying event.
No → Both deadlines run independently, and missing either creates separate compliance exposure.
Does the qualifying event involve a disability extension?
If a qualified beneficiary is determined disabled by the Social Security Administration within the first 60 days of COBRA coverage, a separate 30-day beneficiary notice obligation to the plan administrator applies to preserve the 11-month disability extension. The employer's direct role in this notice is limited, but the plan's written procedures must address it.

Failure to provide a timely qualifying event notice can expose an employer to excise taxes under IRC §4980B of $100 per day per qualified beneficiary for uncorrected violations, with a maximum of $200 per day when a family is affected (IRS, IRC §4980B(b)(1)). The DOL may also pursue civil enforcement under ERISA §502(c), which authorizes penalties of up to $110 per day per violation against plan administrators (DOL ERISA §502(c) enforcement).
