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 |
