How Long Can You Get COBRA: 18, 29, or 36 Months

How long you can get COBRA depends on what caused you to lose coverage and who in the family is continuing it. The standard maximum is 18 months when the trigger is a job loss or a cut in hours. Spouses and dependent children can keep coverage up to 36 months when the triggering event is the employee’s death, divorce or legal separation, the employee becoming entitled to Medicare, or a child aging out of the plan. A Social Security disability determination can stretch the 18-month period to 29 months. Every one of these figures is a ceiling that assumes premiums are paid on time and notification deadlines are met.¹

18 Months After a Job Loss or Reduced Hours

If you leave a job voluntarily, get laid off, or have your hours cut enough to lose benefits eligibility, you and your covered dependents can continue the same group health plan for up to 18 months.¹ The clock starts on the date of the qualifying event, and the coverage must be identical to what similarly situated active employees receive: the same medical, dental, and vision benefits at the same levels.²

The one situation in which an employer can refuse COBRA entirely is termination for gross misconduct. Federal law doesn’t define the phrase, and no COBRA regulation spells it out. The Department of Labor has noted that being fired for ordinary reasons like excessive absences or poor performance does not amount to gross misconduct.³ Courts have generally reserved the label for extreme conduct such as violence, theft, or deliberate sabotage. A denial that doesn’t fit those facts can be challenged.

36 Months for Spouses and Dependents

Spouses and dependent children get a longer window when the triggering event is one of the following: the covered employee’s death, a divorce or legal separation, the employee becoming entitled to Medicare, or a dependent child aging out of the plan. In each of these cases, the maximum period is 36 months from the date of the qualifying event.¹

The Medicare scenario carries a specific wrinkle. When the covered employee becomes entitled to Medicare and then loses the job within 18 months, the coverage period for the spouse and dependents is measured from the date of Medicare entitlement, not from the later job loss.¹

To secure any 36-month period, the spouse or dependent must notify the plan administrator of the qualifying event. Plans must allow at least 60 days, measured from the latest of when the event occurred, when coverage would actually be lost, or when the beneficiary was informed of the notification requirement.⁴ Missing that deadline can forfeit the entire 36-month window.

29 Months When a Disability Extends the Standard Period

If anyone in your family covered under COBRA is determined by the Social Security Administration to be disabled, the standard 18 months extends to 29 months for every qualified beneficiary on that policy.¹ The disability must have existed at some point during the first 60 days of COBRA coverage, and it must continue through the rest of the initial 18-month period.⁴

Notification timing is critical. The disabled beneficiary must give the plan the SSA determination before the original 18 months run out. Plans must give you at least 60 days to provide this notice after receiving the SSA determination letter, but you can’t wait past the 18-month expiration. Applying to SSA early gives you room if their processing runs long.⁴

Cost changes during the added months. Regular COBRA premiums are capped at 102 percent of the plan’s cost, but the disability-extension months can be charged at 150 percent.² For someone managing a serious condition, the extra 11 months of continuous coverage can still be worth it.

Turning 18 Months into 36 with a Second Qualifying Event

If a second qualifying event occurs while a spouse or dependent is already on the initial 18 months of COBRA, coverage can extend to a total of 36 months measured from the original qualifying event. The second event must be one that would independently entitle the beneficiary to 36 months: the covered employee’s death, divorce or legal separation, the employee becoming entitled to Medicare, or a child aging out of the plan.⁴

A common scenario: an employee loses a job and the whole family goes on 18-month COBRA. Six months later, the employee and spouse divorce. The spouse can now extend coverage to a total of 36 months from the original job loss date, adding 18 months beyond what was initially available. The plan must be notified of the second event within the timeframe it sets, which cannot be shorter than 60 days.⁴ The 36-month cap is absolute. No combination of events pushes coverage beyond that ceiling.

Election and Payment Deadlines That Preserve the Maximum

Once you receive the election notice from the plan administrator, you have at least 60 days to decide whether to elect COBRA. That period runs from the later of when coverage actually terminated or when the election notice was provided.⁵

After electing, you have 45 days to make your first premium payment.⁶ That first payment must cover every premium back to the date your prior coverage ended, because COBRA is retroactive to the qualifying event.⁷ Each subsequent payment gets a 30-day grace period from the due date set by the plan. Miss it by a day and the plan can terminate your coverage permanently.⁸

When Coverage Ends Before You Hit the Maximum

The 18, 29, and 36-month figures are ceilings, not guarantees. Coverage can end earlier in several situations:⁸

You miss a premium payment and the 30-day grace period runs out. Plans have no obligation to reinstate you.
Your former employer stops offering group health insurance to any employees, so there is no plan left to continue.
You enroll in another employer’s group health plan that doesn’t exclude your preexisting conditions.
You become entitled to Medicare after your COBRA election date. This ends coverage for the beneficiary who became Medicare-entitled, not necessarily for other family members on the same policy.
Conduct occurs that would justify terminating an active employee’s coverage.

The new-coverage rule catches people during gaps. If your new employer’s plan has a waiting period, COBRA can bridge it, but the moment the new plan takes effect, COBRA ends regardless of how many months remain on your maximum.

Cost and the Marketplace Alternative

Duration is only half the decision. Under COBRA you pay the full cost that you and your employer were both contributing, plus a 2 percent administrative fee, for a total of 102 percent of the plan’s cost.² Many people are shocked by the number because they were used to seeing only the employee share on their paycheck.

Losing job-based coverage qualifies you for a 60-day Special Enrollment Period on the Health Insurance Marketplace, so a marketplace plan is available from day one instead of COBRA.⁹ Marketplace plans may carry premium tax credits based on your income; COBRA does not. If your income dropped when you lost the job, those subsidies can reduce a marketplace premium to a fraction of the COBRA figure.

COBRA’s genuine advantage is that it keeps you on the same plan with the same provider network. If you’re mid-treatment with a specialist or have already met your deductible for the year, switching plans has a real cost. Some people elect COBRA for a few months to finish treatment and then switch to a marketplace plan during Open Enrollment.

One trap: if you elect COBRA and later want to drop it early for a marketplace plan, you generally can only switch during Open Enrollment. Voluntarily dropping COBRA outside of Open Enrollment does not trigger a Special Enrollment Period.¹⁰ When COBRA actually runs out at the end of its maximum period, that exhaustion does qualify you for a 60-day Special Enrollment Period.¹¹

If Your Employer Has Fewer Than 20 Employees

Federal COBRA applies only to private-sector and state or local government employers who had at least 20 employees on more than half of their typical business days in the prior calendar year.² If your employer is smaller than that, the federal 18, 29, and 36-month periods do not apply to you. Roughly 40 states have their own continuation coverage laws, sometimes called mini-COBRA, that fill this gap. These laws vary in who they cover, how long coverage lasts, and what they cost, with durations ranging from a few months up to 36 months depending on the state. Contact your state’s department of insurance to find out what applies where you live.

Coverage Periods at a Glance

18 months: job loss or reduced hours, for the employee and all covered family members.
29 months: same as above, if a covered beneficiary is disabled during the first 60 days.
36 months: death of the employee, divorce, legal separation, Medicare entitlement, or a child aging out of the plan, for spouses and dependents. Also the ceiling when a second qualifying event extends an initial 18-month period.

Every one of these figures assumes you pay every premium on time and notify the plan of every qualifying event within the required window. Mark each date on your calendar the moment your election notice arrives, because the deadlines are firm and the consequences of missing them are permanent.
