When you lose job-based health insurance, one of the first questions is: how long can I stay on COBRA? The honest answer is: it depends. Most people get 18 months. Some qualify for 29 or even 36 months. And if you work for a small employer in Florida, different rules may apply entirely.
This guide breaks down every COBRA duration scenario so you know exactly how long your safety net lasts — and what your options are when it runs out.
Standard 18-Month COBRA Coverage
For the vast majority of people — employees who were laid off, fired, quit, or had their hours reduced below the plan's full-time threshold — COBRA lasts up to 18 months. That "up to" is important: 18 months is the maximum, not a guarantee. Your coverage ends on the last day of the 18th month following your qualifying event.
The clock starts on the date of the qualifying event (typically your last day of employment or the date hours were reduced), not on the date you elect COBRA or the date your first premium is due. So if you wait several weeks to decide before electing COBRA, you're using up time on that 18-month clock before your coverage even kicks in — retroactively, but still.
Example: You were laid off on January 15, 2026. You have until March 15 (60 days) to elect COBRA. If you elect it, your COBRA coverage runs through July 15, 2027 — 18 months from the qualifying event date, regardless of when you elected it.
Who qualifies for 18-month COBRA?
The following qualifying events trigger 18-month COBRA for employees:
- Involuntary termination (layoff, reduction in force, firing)
- Voluntary resignation
- Reduction in hours below the plan's full-time threshold (e.g., from 40 to 28 hours per week)
- Strike or lockout (in some cases)
Dependents who lose coverage because of one of these employee events also get 18 months.
29-Month Extension for Disability
If you or any covered family member is determined to be disabled by the Social Security Administration (SSA) — and that determination happens within the first 60 days of COBRA coverage — you may be eligible to extend COBRA from 18 months to 29 months.
To qualify, all of these conditions must be met:
- The disability must exist at the time of the qualifying event or within the first 60 days of COBRA
- The SSA must formally determine the person to be disabled (Social Security Disability Insurance or SSI determination)
- You must notify the plan administrator of the disability determination within 60 days of receiving it and before the end of the standard 18-month period
Important: During the 29th-month extension period, the plan can charge up to 150% of the full premium — not the usual 102%. The extra 48% is allowed because of the higher expected healthcare costs for disabled individuals.
The 29-month extension covers all qualified beneficiaries on the plan, not just the person who is disabled. So if a covered spouse is disabled, the entire family's COBRA can extend to 29 months.
36-Month Coverage for Dependents
Dependents can receive COBRA for up to 36 months when one of the following qualifying events occurs:
- Death of the covered employee — a covered spouse or dependent children can elect 36 months of COBRA
- Divorce or legal separation from the covered employee — the former spouse and dependent children can elect 36 months
- The covered employee becomes eligible for Medicare — covered dependents may elect 36 months
- A dependent child loses eligibility under the plan's rules (e.g., turning 26, no longer a student if the plan required it) — up to 36 months
Note that these 36-month scenarios apply to dependents, not to the employee. An employee who retires, for example, only gets 18 months — unless they separately become Medicare-eligible, in which case their dependents could get 36 months.
Divorce tip: If you are divorcing a spouse who carries the health insurance, you have 60 days from the divorce date to elect COBRA. This is one of the most time-sensitive qualifying events because many spouses don't know their COBRA rights until weeks after the divorce is finalized. Don't miss it.
Florida Mini-COBRA for Small Employers
Federal COBRA law applies to employers with 20 or more employees. If your employer has fewer than 20 workers, you're not entitled to federal COBRA. However, Florida's "mini-COBRA" law fills part of this gap.
Under Florida Statute §627.6692, employees of Florida employers with 2 to 19 employees may continue their group health coverage for up to 18 months, mirroring the federal COBRA duration. The qualifying events and premium rules are similar to federal COBRA.
If you work for a business with fewer than 2 employees (a sole proprietor, for example), neither federal COBRA nor Florida mini-COBRA applies. Your best option in that case is an ACA marketplace plan during your Special Enrollment Period.
When COBRA Ends Before 18 Months
Even if you're within your maximum coverage period, your COBRA will terminate early in any of these situations:
What Happens When COBRA Runs Out?
The expiration of COBRA is itself a qualifying life event that triggers a Special Enrollment Period (SEP) for ACA marketplace plans. You'll have 30–60 days after COBRA ends to enroll in a new plan without waiting for Open Enrollment.
Here's something many people miss: you don't have to wait until COBRA expires to switch to the marketplace. You can drop COBRA and enroll in a marketplace plan any time. The original qualifying event (job loss) already gave you a 60-day SEP window. And while you can enroll in COBRA retroactively and then drop it later, once you've switched to a marketplace plan you cannot go back to COBRA.
The smart move for most people: Use your original 60-day SEP window to compare COBRA vs. marketplace options side by side. For people earning under 400% of the Federal Poverty Level, marketplace plans with subsidies are often $200–$800/month cheaper than COBRA for equivalent coverage.

| Disability (SSA determination within 60 days) | All qualified beneficiaries | 29 months |
| Death of covered employee | Surviving spouse + dependent children | 36 months |
| Divorce / legal separation | Ex-spouse + dependent children | 36 months |
| Employee becomes Medicare-eligible | Covered dependents only | 36 months |
| Dependent loses eligibility (e.g., turns 26) | The dependent only | 36 months |
Frequently Asked Questions
Does COBRA end if I get a new job?
Yes — COBRA ends the moment you become eligible for new group health coverage, which typically happens on your new employer's plan effective date. You don't need to notify your former plan; coverage terminates by law.
Can I add COBRA after 18 months if I still need it?
No. Once the standard 18-month COBRA period ends (or the extended period), you cannot renew or restart COBRA. You can, however, enroll in a new marketplace plan using the SEP triggered by COBRA exhaustion.
What's the grace period for late COBRA payments?
COBRA law requires plans to give you at least a 30-day grace period for monthly premium payments (45 days for the very first payment). If you pay within the grace period, coverage is restored retroactively. But if you miss the grace period deadline, your COBRA terminates and cannot be reinstated.
Does COBRA coverage reset if I have a second qualifying event?
In some cases, yes. A "second qualifying event" — such as divorce or the death of the covered employee occurring while someone is already on COBRA — can extend the coverage period to 36 months from the original qualifying event. You must notify the plan administrator within 60 days of the second qualifying event.
