If you get a new job, COBRA does not end automatically. It keeps running until you’re actually enrolled in your new employer’s group health plan, which means it can bridge the waiting period most new hires face before benefits begin. Federal law lets your former employer cut off COBRA on the date you first become covered under another group plan, not the date you become eligible for one.1Office of the Law Revision Counsel. 29 USC 1162 – Continuation Coverage The practical question is whether paying up to 102% of the full premium is worth it, or whether a Marketplace plan makes more sense for the weeks or months between jobs.
You Have 60 Days to Decide
You don’t have to elect COBRA the day you leave your old job. Federal law gives you 60 days from the later of two dates: the day you lose coverage or the day you receive the election notice from your former employer’s plan administrator.2U.S. Department of Labor, Employee Benefits Security Administration (EBSA). An Employee’s Guide to Health Benefits Under COBRA
That window is a genuine safety net. If your new employer’s benefits start within 60 days and you stay healthy in the meantime, you may never need to elect COBRA at all. If something serious happens during the gap, you can elect retroactively within the 60 days and coverage applies back to the date you originally lost it, with claims from the gap period reprocessed as covered. Once you elect, the plan must give you at least 45 days to make your first premium payment.3U.S. Department of Labor. An Employee’s Guide to Health Benefits Under COBRA
Miss the 60-day deadline and the right disappears. For anyone with a chronic condition, an ongoing prescription, or scheduled care, paying premiums from day one is safer than gambling on the retroactive option.
Bridging the New Employer’s Waiting Period
Federal regulations bar employers from imposing a waiting period longer than 90 days before new-hire health benefits take effect.4eCFR. 45 CFR 147.116 – Prohibition on Waiting Periods That Exceed 90 Days Some employers start coverage on your hire date, some on the first of the following month, and others run out the full 90 days. Until your new plan is active, COBRA keeps you on the same insurance you had at your previous job, with the same network, deductible, and formulary.
The math shifts with the length of the wait. If your new benefits start in 30 days, one month of COBRA might be worth the continuity. If you’re facing a 90-day wait, individual coverage can run past $2,000 before your new plan kicks in, and a short-term Marketplace plan may cost far less.
When the New Plan Actually Ends Your COBRA
The statute is specific: your former employer’s plan can terminate your COBRA on the date you first become covered under another group health plan.1Office of the Law Revision Counsel. 29 USC 1162 – Continuation Coverage Eligibility alone doesn’t do it. If your new employer offers benefits on day one but you haven’t finished enrollment paperwork, COBRA continues. If your new plan has a 60-day waiting period, COBRA continues through those 60 days no matter what’s technically on offer.
The statute also blocks the new plan from applying preexisting-condition exclusions that would leave you with gaps.1Office of the Law Revision Counsel. 29 USC 1162 – Continuation Coverage In practice, the ACA already bars those exclusions in nearly all group plans, but the safeguard remains on the books.
What COBRA Costs During the Gap
While you were employed, your employer likely covered 70% to 80% of your premium. Under COBRA, you pay the entire premium plus an administrative surcharge of up to 2%, for a total of 102% of the plan’s full cost.5eCFR. 26 CFR 54.4980B-8 – Paying for COBRA Continuation Coverage Individual coverage typically runs $400 to $700 per month. Family coverage often lands between $2,000 and $3,000.
If you have a Health Savings Account, you can use those funds tax-free to pay COBRA premiums. It’s one of the few situations in which HSA money can cover insurance premiums at all.6Internal Revenue Service. Publication 969 – Health Savings Accounts and Other Tax-Favored Health Plans For someone with a well-funded HSA, a short bridge between jobs becomes much more manageable.
The Marketplace Alternative
COBRA isn’t the only option when you leave a job. Losing employer-sponsored coverage triggers a 60-day special enrollment period on the Health Insurance Marketplace, and coverage can start as early as the first day of the month after you lose your previous plan.7HealthCare.gov. See Your Options If You Lose Job-Based Health Insurance A Marketplace plan often costs less than COBRA, particularly if your reduced income during the gap qualifies you for premium tax credits.
The trade-off is continuity. COBRA keeps your exact plan, doctors, and deductible progress. A Marketplace plan may use a different network, reset your deductible, and change which drugs are covered. If you’re mid-treatment or established with specialists, paying for COBRA can be worth it. If you’re generally healthy and need coverage for a few months, the Marketplace usually wins on price.
One catch matters once your new job is in place: if your new employer’s plan is considered affordable, meaning your share of the premium for the lowest-cost option is less than 9.96% of household income in 2026, you won’t qualify for Marketplace premium tax credits even if you skip the employer plan.7HealthCare.gov. See Your Options If You Lose Job-Based Health Insurance
Your Spouse and Children Decide Separately
Each person covered under the former employer’s plan has an independent right to elect COBRA. If you take your new employer’s coverage but your spouse or children aren’t eligible for the new plan, or face a longer waiting period there, they can stay on COBRA even though you drop it.2U.S. Department of Labor, Employee Benefits Security Administration (EBSA). An Employee’s Guide to Health Benefits Under COBRA A parent or legal guardian can elect on behalf of a minor child.
Your family isn’t locked into whatever choice you make about your own coverage, which matters when a new employer’s dependent rules don’t match your old plan’s.
Don’t Drop COBRA Early by Mistake
If your COBRA coverage runs its full course and expires, that triggers a special enrollment period at your current employer’s plan. You get at least 30 days after exhaustion of COBRA to enroll, without waiting for open enrollment, and the right extends to any dependents who were covered.8eCFR. 29 CFR 2590.701-6 – Special Enrollment Periods
The trap is the word “exhausted.” Voluntarily cancelling COBRA before it expires, say at month 12 of an 18-month period, generally does not open a special enrollment period at the new employer. You’d wait for the next open enrollment, which can mean months uninsured. Either keep COBRA running until it expires or time the cancellation to line up with the start of your new employer’s coverage.
Ending COBRA also opens a 60-day special enrollment period to buy a Marketplace plan.9Centers for Medicare & Medicaid Services. Transitioning from Employer-Sponsored Coverage to Other Health Coverage Useful if your new employer offers no health benefits or the plan doesn’t fit your situation.
Tell the COBRA Administrator Once Your New Plan Starts
Once your new employer’s coverage begins, notify your former employer’s COBRA plan administrator. The statute doesn’t set a specific deadline for beneficiaries, but written notice stops premium billing, prevents overpayment disputes, and creates a paper trail of continuous coverage that your new plan may ask to see.2U.S. Department of Labor, Employee Benefits Security Administration (EBSA). An Employee’s Guide to Health Benefits Under COBRA
Some plans bill for a full month even if your new coverage starts mid-month, so time the transition where you can. If your new plan starts on the 15th, you may still owe COBRA for the full month. Keep the enrollment confirmation from your new plan and any correspondence with the COBRA administrator in case a billing question comes up later.
Two Situations That Change the Analysis
If you’re 65 or older, COBRA does not count as coverage from a current employer for Medicare purposes. You have an 8-month special enrollment period after you stop working, or lose the employer’s insurance, whichever comes first, to sign up for Medicare Part B without a late penalty.10Medicare.gov. COBRA Coverage Miss it and the Part B penalty adds 10% to your premium for every full year you could have enrolled but didn’t, for life. In 2026, the standard Part B premium is $202.90 per month; a two-year delay pushes that to $243.50 permanently.11Medicare.gov. Avoid Late Enrollment Penalties A COBRA plan can also reduce what it pays if Medicare should have been primary. Enroll in Medicare first and treat COBRA as supplemental at best.
Federal COBRA also only applies to employers with 20 or more employees.12Legal Information Institute (LII) / Cornell Law School. Consolidated Omnibus Budget Reconciliation Act (COBRA) If your former employer was smaller than that, federal law is silent, but roughly a dozen states and the District of Columbia have “mini-COBRA” laws with their own durations, deadlines, and premium rules. Check with your state insurance department before assuming you have nothing to continue.
