Quick Answer: What Is COBRA?
COBRA (Consolidated Omnibus Budget Reconciliation Act) is a federal law that gives employees and their families the right to continue their employer-sponsored group health insurance after certain qualifying events that would otherwise end their coverage. The law was enacted in 1986 and is enforced by the Department of Labor (DOL), the IRS, and the Department of Health and Human Services (HHS).
COBRA applies to employers with 20 or more employees on more than 50% of typical business days in the prior calendar year. Both full-time and part-time employees count toward the 20-employee threshold.
| Key Fact | Detail |
|---|---|
| Applies to | Employers with 20+ employees |
| Coverage type | Group health plans (medical, dental, vision) |
| Duration | 18, 29, or 36 months depending on qualifying event |
| Cost to employee | Up to 102% of the total premium |
| Employer penalty | $110/day per qualified beneficiary for notification failures |
Who Is Covered by COBRA?
Covered Employers
COBRA applies to private-sector employers with 20 or more employees, as well as state and local governments. Federal government employees are covered under a similar but separate provision. Church plans are generally exempt.
The 20-employee count includes:
- Full-time employees
- Part-time employees (counted as a fraction based on hours worked)
- Employees on leave (FMLA, disability, etc.)
The count is evaluated on a day-by-day basis. If the employer had 20 or more employees on more than 50% of its typical business days in the prior calendar year, COBRA applies.
Qualified Beneficiaries
A qualified beneficiary is anyone who was covered under the employer group health plan on the day before a qualifying event. This includes:
- The employee (covered employee)
- The employee spouse
- The employee dependent children
- Children born to or adopted by the covered employee during the COBRA period (they can be added as qualified beneficiaries)
Covered Plans
COBRA applies to group health plans that provide:
- Medical insurance
- Dental insurance
- Vision insurance
- Prescription drug coverage
- Health FSAs (with limitations)
- Employee assistance programmes (EAPs) that provide medical care
COBRA does not apply to:
- Life insurance
- Disability insurance
- Health savings accounts (HSAs)
- Stand-alone dental or vision plans that are not part of the group health plan
Qualifying Events
A qualifying event is a life event that would cause a covered individual to lose their group health coverage. The type of qualifying event determines the maximum COBRA coverage period.
18-Month Qualifying Events
| Event | Affected Beneficiaries |
|---|---|
| Voluntary termination of employment | Employee, spouse, dependents |
| Involuntary termination (except gross misconduct) | Employee, spouse, dependents |
| Reduction in work hours | Employee, spouse, dependents |
36-Month Qualifying Events
| Event | Affected Beneficiaries |
|---|---|
| Death of the covered employee | Spouse, dependents |
| Divorce or legal separation | Spouse, dependents |
| Covered employee becomes eligible for Medicare | Spouse, dependents |
| Dependent child loses dependent status | Dependent child |
29-Month Extension for Disability
If a qualified beneficiary is determined by the Social Security Administration (SSA) to be disabled at the time of the qualifying event or within the first 60 days of COBRA coverage, the 18-month period can be extended to 29 months for all qualified beneficiaries in the family. During the 11-month extension, the employer can charge up to 150% of the total premium (instead of 102%).
The disabled beneficiary must notify the plan administrator of the SSA disability determination within 60 days of the determination and before the end of the initial 18-month period.
Second Qualifying Events
If a second qualifying event occurs during the initial 18-month COBRA period (such as the former employee dying, divorcing, or becoming Medicare-eligible), the spouse and dependent children can extend their coverage to a total of 36 months from the date of the original qualifying event.
Notification Requirements and Timelines
COBRA has strict notification requirements for both employers and qualified beneficiaries. Missing these deadlines can result in significant penalties.
Employer Notification Obligations
Step 1: Notify the plan administrator of the qualifying event
For employer-triggered qualifying events (termination, reduction in hours, death, Medicare eligibility), the employer must notify the plan administrator within 30 days of the event.
For employee-triggered qualifying events (divorce, dependent losing status), the qualified beneficiary must notify the plan administrator within 60 days of the event.
Step 2: Plan administrator sends the COBRA election notice
The plan administrator must send the COBRA election notice to each qualified beneficiary within 14 days of receiving notice of the qualifying event. This means the total time from qualifying event to election notice delivery is:
- 44 days maximum for employer-triggered events (30 + 14)
- 74 days maximum for employee-triggered events (60 + 14)
What the Election Notice Must Include
The DOL model election notice (available at dol.gov) includes:
- Identification of the qualifying event and date
- Names of qualified beneficiaries entitled to elect COBRA
- Description of the coverage available
- The monthly premium amount
- The election deadline (60 days)
- How to elect COBRA coverage
- The maximum duration of COBRA coverage
- A statement that the coverage is identical to active employee coverage
- Contact information for questions
Initial General Notice
Employers must also provide a general COBRA notice to all employees and their spouses when they first become covered under the group health plan. This notice explains COBRA rights in general terms and instructs covered individuals on how to report qualifying events. Most employers include this in new-hire benefit enrollment materials.
The Election Period
Qualified beneficiaries have 60 days to elect COBRA coverage. The 60-day period runs from the later of:
- The date the qualifying event occurs, or
- The date the election notice is provided
If a qualified beneficiary does not elect COBRA within this window, the right to coverage is permanently waived. However, if the election notice is sent late, the beneficiary gets a full 60 days from when they actually receive it.
Retroactive Coverage
COBRA coverage is retroactive to the date of the qualifying event, even if the beneficiary does not elect until the end of the 60-day window. This means:
- Any medical claims incurred between the qualifying event and the election date will be covered
- The beneficiary must pay premiums back to the qualifying event date
- The beneficiary has 45 days after electing to make the initial premium payment (covering all retroactive months)
Premium Payments
How Much Does COBRA Cost?
Qualified beneficiaries pay up to 102% of the total plan cost -- both the employer and employee portions of the premium, plus a 2% administrative fee.
Example: If the monthly premium for family coverage is $2,000, and the employer previously paid $1,500 while the employee paid $500, the COBRA premium would be $2,000 x 1.02 = $2,040/month.
This is often a significant shock to former employees, who may have been paying only $500/month while employed.
For the 11-month disability extension (months 19-29), the maximum premium increases to 150% of the total cost.
Grace Periods for Payment
- Initial payment: 45 days after electing COBRA
- Subsequent payments: 30-day grace period after each monthly due date
If a beneficiary fails to make a timely payment (including within the grace period), the plan can terminate COBRA coverage retroactive to the last day covered by the last timely payment.
Premium Assistance and Subsidies
During the COVID-19 pandemic, the American Rescue Plan Act (ARPA) provided a 100% COBRA premium subsidy for workers who lost coverage due to involuntary termination or reduction in hours (April-September 2021). While this specific subsidy has expired, similar provisions may be enacted in future legislation.
When COBRA Coverage Ends
COBRA coverage terminates on the earliest of:
- The end of the maximum coverage period (18, 29, or 36 months)
- The date the employer terminates all group health plans
- The date the qualified beneficiary fails to make a timely premium payment
- The date the qualified beneficiary becomes covered under another group health plan (unless the new plan has a pre-existing condition exclusion that applies)
- The date the qualified beneficiary becomes entitled to Medicare
- The date the qualified beneficiary engages in conduct that would justify plan termination (such as fraud)
Early Termination Notices
If the plan terminates COBRA coverage early for any reason other than failure to pay premiums, the plan administrator must provide written notice of early termination as soon as practicable.
Employer Penalties for Non-Compliance
COBRA violations can be extremely costly:
IRS Excise Tax
Under IRC Section 4980B, a non-compliant employer faces an excise tax of $100 per day per qualified beneficiary for each day of the violation. For a family of four, this amounts to $400/day or approximately $12,000 per month.
The maximum excise tax for unintentional failures is the lesser of 10% of the amount paid by the employer for group health plans during the prior year, or $500,000.
DOL Penalties
The DOL can assess penalties of up to $110 per day for failure to provide required COBRA notices.
Private Lawsuits
Qualified beneficiaries can sue for:
- The cost of medical care they would have received under COBRA coverage
- Statutory penalties of up to $110/day
- Attorney fees and costs
- Injunctive relief (requiring the employer to provide COBRA coverage)
Common Compliance Failures
- Late notification: Failing to send the election notice within the required timeframe
- Incomplete notices: Omitting required information from the election notice
- Incorrect premium calculations: Charging more than 102% of the plan cost
- Failure to offer COBRA: Not identifying all qualifying events or qualified beneficiaries
- Improper termination: Ending COBRA coverage for an invalid reason
- No initial general notice: Failing to provide the general COBRA notice to new plan participants
State Mini-COBRA Laws
For employers with fewer than 20 employees who are not subject to federal COBRA, many states have their own continuation coverage laws (often called "mini-COBRA"):
| State | Employer Size | Duration |
|---|---|---|
| California (Cal-COBRA) | 2-19 employees | 36 months |
| New York | 1+ employees | 36 months |
| Texas | 1+ employees | 6-9 months |
| Florida | 1+ employees | 18 months |
| Illinois | 1+ employees | 12 months |
| Massachusetts | 2-19 employees | 36 months |
| Connecticut | 1+ employees | 30 months |
| New Jersey | 2-50 employees | 12 months |
| Ohio | 1+ employees | 12 months |
| Colorado | 1+ employees | 18 months |
Some states also extend coverage beyond federal COBRA. For example, California Cal-COBRA provides an additional 18 months of coverage (for a total of 36 months) after the federal 18-month COBRA period expires.
COBRA vs the ACA Marketplace
Since the Affordable Care Act (ACA) marketplace exchanges opened in 2014, employees facing a qualifying event have an alternative to COBRA: purchasing individual coverage through the marketplace.
Key Differences
| Factor | COBRA | ACA Marketplace |
|---|---|---|
| Cost | 102% of group plan premium | Varies; subsidies available based on income |
| Network | Same as employer plan | Varies by plan |
| Continuity | Same doctors, same plan | May need to switch providers |
| Enrollment | 60-day election period | 60-day Special Enrollment Period |
| Duration | 18-36 months | Ongoing (annual renewal) |
| Income-based subsidies | Not available | Available if income is 100-400% FPL |
When COBRA Makes More Sense
- The employee is mid-treatment and needs to keep their current doctors and network
- The employer plan has richer benefits than available marketplace plans
- The employee income is too high for meaningful ACA subsidies
- The employee wants seamless coverage during the transition
When the ACA Marketplace Makes More Sense
- The employee income qualifies for premium tax credits (significant savings)
- COBRA premiums are unaffordable (as they often are for family coverage)
- The employee does not need the specific network of the employer plan
- The employee wants coverage beyond the COBRA maximum duration
COBRA Administration Best Practices
Automating COBRA Compliance
Given the strict timelines and severe penalties, most employers with 20+ employees use a third-party COBRA administrator (TPA) or their HRIS/benefits platform to manage COBRA compliance:
- Automated qualifying event detection from HR system termination/status change records
- Template-driven election notices with required content
- Premium billing, collection, and reconciliation
- Tracking of election periods, payment deadlines, and coverage end dates
- Documentation and audit trail for DOL/IRS compliance
Key Process Steps for Employers
- Identify the qualifying event within the HR or benefits system
- Notify the plan administrator within 30 days
- Verify the election notice is sent within 14 days of plan administrator notification
- Track the 60-day election window and follow up if no response
- Process premium payments and monitor grace periods
- Send early termination notices when applicable
- Maintain records for at least 6 years (recommended)

Frequently Asked Questions
How long does COBRA coverage last?
COBRA coverage lasts 18 months for qualifying events related to termination or reduction in hours. It extends to 29 months if a qualified beneficiary is disabled, and to 36 months for qualifying events such as death of the employee, divorce, or Medicare eligibility. A second qualifying event during the initial 18-month period can also extend coverage to 36 months for the spouse and dependents.
How much does COBRA cost the employee?
Qualified beneficiaries pay up to 102% of the total premium cost -- both the employer and employee portions, plus a 2% administrative fee. For example, if the total monthly premium for family coverage is $2,000 and the employer previously covered $1,500, the COBRA premium would be $2,040/month. During the disability extension (months 19-29), the premium can increase to 150% of the total cost.
What happens if an employer fails to send the COBRA notice on time?
Employers face an IRS excise tax of $100 per day per affected qualified beneficiary for each day of the violation. The DOL can also assess penalties of $110/day. Qualified beneficiaries can file private lawsuits seeking the cost of medical care they would have received, statutory penalties of up to $110/day, and attorney fees. For a family of four, penalties can exceed $12,000 per month.
Does COBRA apply to small businesses?
Federal COBRA applies only to employers with 20 or more employees. However, many states have "mini-COBRA" laws that extend continuation coverage rights to employees of smaller employers. For example, New York covers employers with 1+ employees, California Cal-COBRA covers employers with 2-19 employees, and Texas covers employers with 1+ employees.
Can an employee choose the ACA marketplace instead of COBRA?
Yes. A qualifying event that triggers COBRA eligibility also creates a 60-day Special Enrollment Period for the ACA marketplace. Employees should compare costs carefully: COBRA maintains the same plan and network but can be very expensive, while marketplace plans may offer premium tax credits based on income. Many former employees find marketplace coverage more affordable, especially for family coverage.
