COBRA premiums in 2026 hit hard because the plan charges 102% of the full cost of coverage, including the share your former employer used to pay. KFF's 2025 Employer Health Benefits Survey puts the average annual employer premium at $9,325 for single coverage and $26,993 for family coverage, which works out to roughly $793 and $2,294 per month on COBRA in 2026 once the 2% administrative fee is added. Many people elect COBRA in a hurry after a layoff, then discover the bill is far above what a subsidized Marketplace plan would cost. The real question is whether you can switch, and the answer depends on timing. Under HealthCare.gov rules for 2026, you can leave COBRA for a Marketplace plan if you are still within 60 days of losing your job-based coverage, if COBRA ends or your employer stops paying its share, or during Open Enrollment for 2027 coverage. Simply stopping COBRA payments mid-year does not open a Special Enrollment Period (SEP), and that mistake leaves people uninsured until the next enrollment window.
Three timing scenarios cover nearly every COBRA holder in 2026. In scenario one, your job-based coverage ended within the last 60 days, so the original loss-of-coverage SEP is still open and you can pick a Marketplace plan at healthcare.gov even though you elected COBRA. In scenario two, more than 60 days have passed and COBRA is still active, so you wait for Open Enrollment (November 1, 2026 through January 15, 2027, with a December 15, 2026 cutoff for a January 1, 2027 start) unless a new qualifying life event such as marriage, a birth, or a move occurs. In scenario three, COBRA is about to run out or your employer is ending its premium help, which opens a fresh 60-day Marketplace SEP. Medicaid and CHIP sit outside all three scenarios because Medicaid accepts applications year-round per medicaid.gov, so a household whose 2026 income falls under 138% of the Federal Poverty Level can leave COBRA at any time. The steps below walk through the decision in order.
6 Steps to Get Coverage
Common Mistakes That Cost People Thousands
Most COBRA switching errors in 2026 come from timing, not from plan choice, and each one can leave a household uninsured or paying twice.
- Stopping COBRA payments to force a switch. A voluntary drop or a missed payment does not open a Special Enrollment Period, so you wait until Open Enrollment with no coverage in between.
- Assuming electing COBRA used up your 60-day window. The original loss-of-coverage SEP stays open for 60 days from the coverage end date even after you elect COBRA, so you can still switch inside that window.
- Canceling COBRA before the Marketplace plan is confirmed. Marketplace coverage starts the first of the month after plan selection and needs the first premium paid, so cancel COBRA only after both are done.
- Underestimating 2026 income. Starting with tax year 2026, the 2025 budget reconciliation law removes the cap on repaying excess advance premium tax credits, so a low estimate can mean a large bill at tax time with Form 1095-A and Form 8962.
- Ignoring provider networks. Marketplace networks are often narrower than a group plan, so compare doctors and drug formularies before you give up COBRA mid-treatment.
Why Dropping COBRA Early Does Not Open a Special Enrollment Period in 2026
HealthCare.gov treats losing coverage involuntarily as a qualifying life event, and choosing to stop paying COBRA premiums on your own does not qualify. Federal rules count COBRA as minimum essential coverage for as long as you hold it, so a voluntary exit looks like a personal decision rather than a loss. KFF's Marketplace FAQ confirms that outside Open Enrollment, a person who drops COBRA voluntarily must wait for the next Open Enrollment, and only exhausting COBRA or an employer ending its contribution creates a new SEP. State-based exchanges such as Covered California, MNsure, and kynect generally follow the same rule, though each runs its own portal and deadlines.
Three exceptions give you a legitimate way out of COBRA before the 18 to 36 month maximum. First, the 60-day SEP that started when your job-based coverage ended still runs even if you elected COBRA. Second, an employer that agreed to pay part of your COBRA premium for a limited time creates a new SEP when that help ends. Third, a new qualifying life event, such as marriage, a birth or adoption, or a move to a new coverage area, opens its own 60-day window regardless of COBRA status. Document the date of each event, because the Marketplace may ask for proof.
How 2026 Premium Tax Credits Change the COBRA Math
Premium tax credits in 2026 cap what you pay for the benchmark Silver plan at a percentage of income set by IRS Rev. Proc. 2025-25: 2.10% below 133% FPL, rising band by band to 9.96% from 300% to 400% FPL. A single person with projected 2026 income of $40,000 (about 251% FPL) pays roughly 8.4% of income, or about $280 per month, for the benchmark plan, compared with about $793 per month for COBRA at 2026 average group premiums. Incomes above 400% FPL ($63,840 for one person in 2026) receive no credit, so very high earners may find COBRA or a spouse's plan closer in cost.
Enrollment in COBRA itself blocks the credit for those months, because COBRA counts as employer-sponsored coverage you are enrolled in. The credit begins only on the Marketplace plan's start date, which is why the cancellation timing in step five matters. Each January the Marketplace sends Form 1095-A, and you reconcile the advance credits on Form 8962. Households with changing income should update their healthcare.gov application whenever 2026 income shifts.
Medicaid Eligibility When COBRA Is Too Expensive in 2026
Medicaid in the 40 expansion states plus DC covers adults under 138% of the Federal Poverty Level, which for 2026 means $22,025 for one person or $45,540 for a family of four. State programs go by different names: California's Medi-Cal, Arizona's AHCCCS, Wisconsin's BadgerCare, Massachusetts's MassHealth, Connecticut's HUSKY Health, and Illinois's AllKids for children. Medicaid accepts applications year-round per medicaid.gov, so no SEP is needed, and a drop in income after a layoff is often what makes a household eligible. The 10 non-expansion states (Alabama, Florida, Georgia, Kansas, Mississippi, South Carolina, Tennessee, Texas, Wisconsin, Wyoming) set stricter adult limits, so most adults there use the Marketplace instead.
Frequently Asked Questions
What is the SEP window if I am on COBRA and want to switch to a Marketplace plan?
Your Marketplace SEP window is 60 days from the date your job-based coverage ended, and electing COBRA does not shorten it. If coverage ended September 30, 2026, you can enroll from October 1 through November 29, 2026 at healthcare.gov, and you may even select a plan up to 60 days before a known loss date. After day 60, a new SEP opens only if COBRA is exhausted, your employer stops paying its share, or a new qualifying life event occurs. Otherwise, Open Enrollment for 2027 coverage runs November 1, 2026 through January 15, 2027, with December 15, 2026 as the cutoff for a January 1, 2027 start.
What documents do I need to switch from COBRA to a Marketplace plan?
Documents for a COBRA-to-Marketplace switch prove the original loss of coverage and your 2026 income. Gather the termination letter or notice showing the date job-based coverage ended, your COBRA election notice and latest premium bill, recent pay stubs or an unemployment award letter, Social Security numbers for everyone applying, and your current address. HealthCare.gov may ask you to upload proof of the qualifying event after you apply, so keep digital copies ready. Dependents added to the plan may need birth certificates or custody papers. Submit documents promptly, because coverage can be cancelled if the Marketplace cannot verify your SEP.
What if I miss the SEP window and I am still on COBRA?
Missing the 60-day SEP while holding COBRA means you stay on COBRA, or go without coverage, until the next qualifying event or Open Enrollment. For 2027 coverage, Open Enrollment runs November 1, 2026 through January 15, 2027, and plans selected by December 15, 2026 start January 1, 2027. Do not stop paying COBRA in the meantime, because a voluntary drop does not create a Special Enrollment Period and a lapse leaves you uninsured. Also ask your former employer whether its COBRA premium help ends on a set date, since that end date opens a new 60-day SEP. Medicaid remains available year-round if your income qualifies.
Can I get retroactive coverage when I switch from COBRA to the Marketplace?
Marketplace coverage under a loss-of-coverage SEP is not retroactive: it starts the first day of the month after you select a plan. COBRA is the option with a retroactive feature, because a COBRA election within its 60-day window reaches back to the day your job-based coverage ended once you pay the first premium. Medicaid can sometimes cover medical bills from up to three months before the application month in many states, if you were eligible then. Time your Marketplace start date to follow your last COBRA day so you avoid both a gap and a double payment.
What is the difference between COBRA and the Marketplace for someone laid off in 2026?
COBRA keeps your exact employer plan, doctors, and met deductible, but you pay 102% of the full premium, roughly $793 per month single or $2,294 per month family in 2026, with no premium tax credit. Marketplace plans price your share by 2026 income, from 2.10% to 9.96% of income for the benchmark Silver plan, so many households pay far less, though the network may change. COBRA can last 18 to 36 months, while Marketplace plans renew yearly. Choose COBRA only for ongoing specialist care or a met deductible, and choose the Marketplace or Medicaid in most other cases.
What state-specific rules apply when I leave COBRA in 2026?
Federal COBRA covers employers with 20 or more employees, while many states run mini-COBRA programs for smaller employers, such as Cal-COBRA in California for up to 36 months. State-based exchanges, including Covered California, MNsure, and kynect, run their own portals but generally apply the same rule that voluntarily dropping COBRA is not a qualifying event. Medicaid brands also vary by state: Medi-Cal, AHCCCS, BadgerCare, MassHealth, and HUSKY Health. Call your state insurance department or exchange to confirm local deadlines, because some states add extra special enrollment events beyond the federal list.
Do I qualify for Medicaid instead of paying COBRA in 2026?
Medicaid qualification in 2026 depends on household size and projected annual income. In the 40 expansion states plus DC, adults qualify under 138% FPL, which is $22,025 for one person, $29,863 for two, and $45,540 for four, using the table on this page. Medicaid accepts applications year-round per medicaid.gov, so you do not need an SEP and can end COBRA the day Medicaid starts. Use projected 2026 income after your layoff, not last year's salary. In the 10 non-expansion states, adult limits are lower, so check your state agency or the healthcare.gov screener.
What happens to my children's coverage if I leave COBRA?
Children on your COBRA plan move with you when you select a Marketplace plan during the SEP, and you can add them to the same application. CHIP and Medicaid for children accept applications year-round, with 2026 income limits typically between 200% and 300% FPL and higher in some states, so children can qualify even when parents do not. Brands include Medi-Cal for Kids, AllKids in Illinois, HUSKY Health in Connecticut, and NJ FamilyCare. Apply through your state agency or healthcare.gov, and ask whether COBRA coverage affects any waiting period. Keep children insured until the new coverage starts to avoid a gap.
