Administering COBRA benefits correctly is one of the more demanding compliance responsibilities for any HR department. COBRA—the Consolidated Omnibus Budget Reconciliation Act—requires employers with 20 or more employees to offer continued health coverage to qualified beneficiaries after specific qualifying events such as job loss, a reduction in hours, or the death of a covered employee. The law is detailed, deadline-driven, and subject to significant financial penalties when mishandled. This COBRA benefits administration guide walks through the essential deadlines, notice requirements, common pitfalls, and practical steps to keep your organization compliant.

What is COBRA?

COBRA is a federal law that requires employers with 20 or more employees to offer continued health coverage to qualified beneficiaries after events like job loss, reduction in hours, or death of a covered employee. The law covers group health plans, dental, and vision coverage offered through the employer’s plan.

Key Deadlines for COBRA Administration

Missing a COBRA deadline can result in penalties from the Department of Labor (DOL), so HR teams must track and meet the following key dates without exception:

  • 30 days after a qualifying event: The employer must notify the group health plan administrator that a qualifying event has occurred and that an individual may be eligible for COBRA.
  • 14 days after the employer notifies the plan: The plan administrator must send the eligible individual a COBRA election notice with all required content.
  • 60 days from the later of the notice date or coverage loss date: The individual has this window to elect COBRA coverage. The election is retroactive to the date coverage was lost.
  • 45 days after election: The qualified beneficiary must make the initial premium payment covering all months since coverage lapsed.
  • 30 days after the end of the COBRA period: The plan must provide written notice that coverage is terminating and advise the individual of any conversion options available.

These timeframes are strictly enforced. One missed notification can trigger per-day penalties that compound quickly. Treegarden supports HR teams by providing structured deadline tracking and automated reminders so no critical date slips through.

Qualifying Events That Trigger COBRA

Qualifying events include: voluntary or involuntary termination of employment (except for gross misconduct), reduction in hours below plan eligibility thresholds, the covered employee becoming entitled to Medicare, divorce or legal separation from the covered employee, death of the covered employee, and a dependent child aging off the plan. Each event type has its own maximum coverage duration.

Required COBRA Notices

COBRA requires a structured set of notices, each with specific content requirements mandated by the DOL. The primary notices your team must manage are:

  • Initial (General) Notice: Must be provided within 90 days of when the employee or dependent first becomes covered under the plan. Often included in new hire benefits materials.
  • Notice of Qualifying Event: Sent by the employer to the plan administrator within 30 days of certain qualifying events (termination, reduction in hours, Medicare entitlement). For events like divorce or a dependent aging off, the employee or dependent must notify the plan within 60 days.
  • COBRA Election Notice: The plan administrator sends this to the qualified beneficiary within 14 days of receiving the qualifying event notice. It must include coverage options, election deadlines, premium amounts, and payment procedures.
  • Notice of Unavailability: Required when a plan administrator receives a qualifying event notice but the individual is not entitled to COBRA—explaining why.
  • Notice of Early Termination: Sent when COBRA coverage ends before the maximum period, specifying the reason and earliest termination date.

All notices must conform to DOL model language or equivalent. Using outdated templates or omitting required disclosures is one of the most common sources of COBRA liability. Review your templates at least annually against current DOL guidance.

COBRA Coverage Durations by Event Type

The maximum period of COBRA continuation coverage depends on the type of qualifying event:

  • 18 months: Job termination (voluntary or involuntary, except gross misconduct) or reduction in hours.
  • 18 months extended to 29 months: If the qualified beneficiary is determined to be disabled by Social Security at the time of the qualifying event or within 60 days, the maximum period extends to 29 months. The beneficiary must notify the plan of the disability determination within 60 days.
  • 36 months: For other qualifying events—death of the covered employee, divorce or legal separation, Medicare entitlement, or a dependent child losing eligibility under the plan.
  • Second qualifying event extension: If a second qualifying event occurs during an initial 18-month COBRA period (e.g., death of the former employee during the covered period), beneficiaries may extend coverage to a maximum of 36 months from the original qualifying event.

Common COBRA Administration Mistakes

Even well-resourced HR departments make avoidable errors in COBRA administration. The most costly include:

  • Missing or delayed notices: Sending the election notice even one day late can expose the employer to per-day DOL penalties and deprive the beneficiary of their legal right to elect coverage.
  • Incorrect calculation of coverage periods: Failing to account for disability extensions, second qualifying events, or the correct start date of the COBRA period leads to under- or over-enrolling beneficiaries.
  • Overlooking eligible dependents: COBRA must be offered to all qualified beneficiaries under the plan—not just the employee. Spouses, former spouses, and dependent children who were covered under the plan must each receive individual notice.
  • Inadequate premium tracking: Beneficiaries have a 30-day grace period for monthly premium payments after the initial 45-day window. Terminating coverage prematurely because of a delayed payment violates COBRA regulations.
  • Using outdated notice templates: Templates must reflect current DOL model language, applicable premium amounts, and updated contact information for the plan administrator.
  • Confusing gross misconduct: Terminating an employee for gross misconduct is a narrow exception to COBRA eligibility—but the standard is very high. Misapplying this exception is a frequent source of litigation.

Using an HR platform like Treegarden reduces these risks significantly by automating notice generation, deadline tracking, and beneficiary management in a single system.

Stay Compliant with Treegarden

Treegarden offers tools and tracking features to help HR teams manage COBRA notices, deadlines, and beneficiary data efficiently and accurately. From automated reminders to document templates aligned with current DOL requirements, the platform reduces the administrative burden of COBRA compliance.

How to Avoid COBRA Penalties

The DOL can impose excise tax penalties of up to $100 per day per qualified beneficiary for COBRA violations, with a minimum penalty of $2,500 per violation. The IRS can impose additional excise taxes under IRC Section 4980B. For HR teams managing large populations, uncorrected violations can quickly reach six figures. To prevent this:

  • Assign a designated COBRA administrator—internal or third-party—with clear accountability for all notices and deadlines.
  • Double-check all notices against the current DOL model notice to confirm required language, formatting, and contact information are present.
  • Maintain a complete COBRA log: qualifying event date, notice sent date, election deadline, election decision, and payment history for every qualified beneficiary.
  • Conduct an annual COBRA process audit, reviewing a sample of recent qualifying events for compliance with all notice and timeline requirements.
  • Train HR and benefits staff on COBRA requirements at least once per year, particularly when there are regulatory updates.

Leveraging Technology for COBRA Administration

Manual COBRA administration is time-consuming and error-prone, particularly for organizations with frequent turnover or large employee populations. HR teams that rely on spreadsheets and manual calendar reminders routinely miss notice deadlines—sometimes through no fault of their own, simply because the qualifying event was not surfaced to the benefits team in time.

Technology solutions that integrate with payroll and HRIS systems can automatically trigger COBRA workflows when qualifying events are recorded. This ensures the 30-day employer notification window is captured, the election notice is queued within the 14-day window, and payment tracking begins once an election is made. Treegarden’s platform connects these workflows in a single interface, allowing HR teams to manage COBRA alongside onboarding, offboarding, and the full employee lifecycle without switching between disconnected tools.

Summary

COBRA benefits administration is detailed, deadline-sensitive, and consequential—non-compliance carries real financial penalties and can deprive departing employees and their families of health coverage they are legally entitled to receive. HR teams that invest in well-designed processes, accurate notice templates, and technology-backed deadline tracking will avoid the most costly errors. Review your COBRA procedures annually, keep your templates current with DOL guidance, and ensure every qualifying event triggers the right workflow immediately.

Stay Ahead of Deadlines

Use an HR system to automate COBRA reminders and ensure all notices are sent on time. A single missed deadline can cost $100 per day per beneficiary—automated tracking eliminates the risk. Treegarden helps HR teams maintain compliance and reduce administrative burden across the full COBRA lifecycle.
