COBRA Administration Guide for Employers (2026): Requirements, Notices and Penalties

COBRA administration is one of the most penalty-heavy areas of employer compliance — and one of the most commonly mismanaged. Miss a notice deadline by a single day, and you could owe $100 per day per affected beneficiary in excise taxes. Fail to send the correct notices to an entire plan, and that number can climb to $200 per day. Yet many employers — especially those who just crossed the 20-employee threshold — don’t realize COBRA applies to them at all.

This guide covers everything employers need to know about COBRA in 2026: which employers are covered, what events trigger it, what notices must go out (and when), how premiums are calculated, how long coverage lasts, and what happens when something goes wrong. Whether you’re self-administering COBRA or evaluating a third-party administrator, this is your compliance roadmap.

What Is COBRA and Which Employers Must Comply?

The Consolidated Omnibus Budget Reconciliation Act (COBRA) is a federal law enacted in 1986 that requires certain employers to offer employees and their covered dependents the option to continue group health coverage after a qualifying event would otherwise cause them to lose it. COBRA does not require employers to pay for that continued coverage — it simply requires them to make it available.

The law is administered jointly by three federal agencies: the Department of Labor (DOL) enforces notice requirements for private-sector group health plans, the IRS enforces the excise tax provisions, and the Department of Health and Human Services (HHS) handles public-sector plans.

Does COBRA Apply to Your Organization?

COBRA applies to private-sector employers and state and local governments that sponsored a group health plan during the previous calendar year and employed 20 or more employees on at least 50% of typical business days. Both full-time and part-time employees count toward the threshold.

Requirement	Detail
Employer size threshold	20+ employees on 50%+ of business days in prior year
Plan type covered	Group health plans (medical, dental, vision)
Who is exempt	Federal government, churches, employers under 20 employees
Governing law	ERISA, IRC Section 4980B, Public Health Service Act
Enforcing agencies	DOL (notice rules), IRS (excise tax), HHS (public plans)
Applies to	Medical, dental, vision, HRA, health FSA (limited)

Small employers with fewer than 20 employees are not subject to federal COBRA but may be subject to state-level “mini-COBRA” laws, which are discussed later in this guide.

COBRA Qualifying Events

A qualifying event is a specific event that causes a covered employee, spouse, or dependent child to lose group health coverage. COBRA is only triggered when a qualifying event occurs and coverage would actually be lost as a result.

Qualifying Events for Covered Employees

Voluntary or involuntary termination of employment (for reasons other than gross misconduct)
Reduction in hours that causes loss of coverage eligibility

Qualifying Events for Spouses and Dependent Children

Employee’s termination or reduction in hours
Employee becomes entitled to Medicare
Divorce or legal separation from the covered employee
Death of the covered employee
Dependent child ages off the plan (typically at age 26)

Termination for gross misconduct is not a qualifying event — but courts interpret “gross misconduct” narrowly and COBRA does not define it. Employers should not withhold COBRA for misconduct-related terminations without legal review.

Who Is a Qualified Beneficiary?

A qualified beneficiary is any individual covered under the group health plan on the day before the qualifying event: the covered employee, their spouse, and their dependent children. Each qualified beneficiary has independent COBRA rights — they can elect coverage separately even if the employee declines. Children born to or adopted by the employee during the COBRA period are automatically qualified beneficiaries. Domestic partners are not qualified beneficiaries under federal COBRA, though some state mini-COBRA laws include them.

COBRA Coverage: What Must Be Offered

COBRA requires the plan to offer qualified beneficiaries the identical coverage they had immediately before the qualifying event. The plan cannot offer a reduced or inferior version. If the active plan offers multiple options, COBRA beneficiaries must be given the same options available to similarly situated active employees during open enrollment. Coverage subject to COBRA includes major medical, dental (separate plan), vision, prescription drug, HRAs (in some cases), and health FSAs when the account is underspent at the qualifying event. Life insurance, disability, and most voluntary benefits are not subject to COBRA.

COBRA Notice Requirements and Deadlines

COBRA notice compliance is where most employers get into trouble. There are multiple distinct notices with strict deadlines. Missing or defective notices are the most common trigger for COBRA excise tax liability and DOL civil penalties.

Notice 1: Initial (General) Notice — Within 90 Days of Coverage Start

When an employee (or their spouse or dependent) first becomes covered under a group health plan, the plan administrator must provide a General Notice of COBRA Continuation Coverage Rights. Deadline: Within 90 days of the date coverage begins. If the employee’s spouse lives at a different address, a separate notice must go to that address.

Notice 2: Employer Qualifying Event Notice — Within 30 Days

When the employer knows about a qualifying event — termination, reduction in hours, death, Medicare entitlement, or bankruptcy — it must notify the plan administrator within 30 days. For qualifying events the employer may not know about (divorce, legal separation, dependent aging off), the plan must have a written procedure for employees and beneficiaries to report them within 60 days.

Notice 3: Election Notice from Plan Administrator — Within 14 Days

After the plan administrator receives notice of a qualifying event, it must send each qualified beneficiary a COBRA Election Notice. Deadline: 14 days from receipt of the qualifying event notice. When the employer and plan administrator are the same entity (self-administered), the combined deadline is 44 days from the qualifying event date. The election notice must be sent to each qualified beneficiary at their last known address separately.

Notice	Sender	Deadline	Recipient
General/Initial Notice	Plan administrator	90 days from coverage start	Employee (and spouse at different address)
Qualifying Event Notice (employer-known)	Employer	30 days from qualifying event	Plan administrator
Qualifying Event Notice (employee-known)	Employee/beneficiary	60 days from qualifying event	Plan administrator
Election Notice	Plan administrator	14 days from QE notice (44 days if self-administered)	Each qualified beneficiary separately
Early Termination Notice	Plan administrator	As soon as practicable	Each qualified beneficiary

COBRA Election Period: 60 Days

Once the Election Notice is provided, each qualified beneficiary has 60 days to elect COBRA. The period begins on the later of: (1) the date coverage would be lost, or (2) the date the Election Notice is provided. Even a day-59 election entitles the beneficiary to retroactive coverage back to the date coverage was lost.

COBRA Premium Rules: 102% of Full Cost

COBRA beneficiaries can be charged the full cost of coverage plus a 2% administrative fee. Example: If the total monthly plan cost is $800, the maximum COBRA premium is $816. For the disability extension period (months 19–29), the premium may be raised to 150% of the full cost. The initial premium is due 45 days after election; subsequent premiums have a mandatory 30-day grace period.

Duration of COBRA Coverage

Qualifying Event	Max Duration	Who Receives This Duration
Termination or reduction in hours	18 months	Employee and covered dependents
Disability (SSA determination within first 60 days)	29 months	Disabled individual and family members
Death of covered employee	36 months	Spouse and dependent children
Divorce or legal separation	36 months	Spouse and dependent children
Employee’s Medicare entitlement	36 months	Spouse and dependent children
Dependent child loses dependent status	36 months	Dependent child
Employer bankruptcy (retiree coverage)	Lifetime for retiree; 36 months for surviving spouse/dependents	Retirees and their families

COBRA Penalties for Non-Compliance

COBRA non-compliance carries some of the most severe automatic penalties in employment law. IRS excise tax under IRC Section 4980B: $100 per day per qualified beneficiary ($200/day family cap). Minimum penalty is $2,500 per qualified beneficiary per failure. DOL civil penalties under ERISA Section 502(c): up to $110 per day per affected participant. Plus direct ERISA litigation exposure for healthcare costs incurred due to lack of COBRA access.

Self-Administering COBRA vs. Third-Party Administrator

Employers have two options for managing COBRA: handle it internally (self-administer) or outsource to a third-party COBRA administrator (TPA). Each has tradeoffs.

	Self-Administering	Third-Party Administrator (TPA)
Cost	Staff time only	Per-participant fee ($2–$8/month typical)
Notice compliance	HR team responsible for all deadlines	TPA tracks and sends all required notices
Premium collection	Employer collects and reconciles	TPA collects premiums and remits to carrier
Carrier coordination	HR enrolls/terminates directly with carrier	TPA handles all carrier communication
Audit trail	Internal records only	TPA maintains documented compliance records
Risk	High — one missed notice = excise tax exposure	Lower — TPA errors may shift liability
Best for	Very small plans with minimal turnover	Most employers — especially 50+ employees

Most HR professionals recommend using a TPA for COBRA unless your organization has very low turnover and a dedicated benefits administrator with strong process controls. The per-participant cost of a TPA is typically far less than the excise tax exposure from a single missed notice.

Mini-COBRA: State Laws for Employers Under 20 Employees

If your business has fewer than 20 employees and is not subject to federal COBRA, you may still be required to offer continuation coverage under your state’s “mini-COBRA” law. These vary significantly by state.

State	Employer Threshold	Max Duration	Key Notes
California	2–19 employees	36 months	Cal-COBRA; same notice rules as federal
New York	2–19 employees	36 months	NY Continuation; covers domestic partners
Texas	2–19 employees	9 months	Shorter duration than most states
Florida	1–19 employees	18 months	Applies to all insured group plans
Illinois	2–19 employees	12 months	Limited to group accident/health insurance
New Jersey	2–19 employees	18 months	NJ Continuation; similar to federal rules
Georgia	2–19 employees	3 months	Very limited; bridge to other coverage only
Massachusetts	2–19 employees	18 months	Administered similarly to federal COBRA
Colorado	2–19 employees	18 months	Covers termination and reduced hours
Virginia	2–19 employees	12 months	Covers termination only
