Turning 26 is a big birthday for health insurance. It's usually the last year you can be on a parent's plan. HealthCare.gov warns that if you don't act, you may end up with no coverage.
This guide explains when your coverage ends, the choices you have, and how to switch without a gap. It covers federal rules. Some states add their own.
When does coverage on a parent's plan end?
Under federal rules, a plan that covers children must let them stay on until age 26. HealthCare.gov says that, in general, you can stay on a parent's job-based plan until 26 even if you:
- Get married.
- Have or adopt a child.
- Start or leave school.
- Live in or out of your parent's home.
- Aren't claimed as a tax dependent.
- Turn down health coverage from your own job.
When your coverage ends depends on the type of plan:
- Parent's job-based plan: HealthCare.gov says it usually ends during or shortly after the month you turn 26. Ask the plan or your parent's employer for the exact date.
- Parent's Marketplace plan: you can stay on through December 31 of the year you turn 26, even if your birthday comes earlier in the year.
Some states have longer rules. For example, Florida law says some group health insurance policies that cover children must offer the option to keep a child covered until the end of the year the child turns 30. The child must be unmarried, have no dependents, live in Florida or be a student, and not have other coverage. It doesn't apply to every plan, so ask the plan.
Your main choices at 26
- Join your own job's health plan, if your job offers one.
- Buy your own Marketplace plan.
- Keep your parent's job-based plan for a while with COBRA, if the plan offers it.
- Apply for Medicaid, if your income is low enough in your state.
The right pick depends on your job, your income, and your health needs. Compare costs before you choose.
Option 1: Your own job's health plan
If your job offers health insurance and you didn't sign up when it was offered, losing a parent's plan at 26 lets you join outside the plan's yearly sign-up time, HealthCare.gov says.
Federal rules give you at least 30 days after you lose coverage to ask to join. Your plan may give you more time. Talk to your HR team before your birthday.
Know this before you say no: if your job offers coverage that counts as affordable and you turn it down, you generally can't get a Marketplace tax credit. As of October 14, 2026, HealthCare.gov says a job plan counts as affordable for 2027 if your share of the monthly premium for the lowest-cost self-only plan is less than 10.22% of your household income. The plan must also meet a minimum value standard.
Option 2: Your own Marketplace plan
How you sign up depends on your parent's plan.
If your parent has a job-based plan, losing that coverage at 26 gives you a Special Enrollment Period. HealthCare.gov says it starts 60 days before you lose coverage and ends 60 days after.
- Enroll before you lose coverage, and your new plan can start as soon as the first day of the month after your old coverage ends.
- Enroll after you lose coverage, and your new plan can start the first day of the month after you pick a plan. That can leave a gap.
HealthCare.gov may ask you to send documents that show you lost coverage and the date it ends. You must send them before you can start using your new plan.
If your parent has a Marketplace plan, you stay on it through December 31. Then you enroll in your own plan for the next year during Open Enrollment. As of October 14, 2026, under current law, Open Enrollment for 2027 runs November 1, 2026, to January 15, 2027, and you must pick a plan by December 15 (the deadline under current law) for coverage to start January 1. A court case about these dates is still on appeal, so check HealthCare.gov. See every date in our Florida open enrollment guide.
If your parent will claim you as a tax dependent for the next year, HealthCare.gov says to stay on your parent's Marketplace application and not make your own account. Your parent can enroll you in your own plan during Open Enrollment.
Will you get help paying for a Marketplace plan?
It depends on your household income for the year you are covered, and on how your family files taxes.
- If no one can claim you as a tax dependent, you may get a tax credit based on your own income, as long as you don't have an offer of affordable job coverage.
- If a parent will claim you as a tax dependent, you can still buy a Marketplace plan. HealthCare.gov says any help is based on your parent's household income, not yours.
As of October 14, 2026, under current law, two IRS rules matter for 2027:
- The premium tax credit is generally only for household incomes from 100% to 400% of the poverty line. The temporary rule that let people above 400% get the credit ended after 2025.
- For tax years after 2025, there is no cap on paying back extra credit. If you get too much during the year, you pay all of the difference back when you file. A tax pro can help.
Under 30? You can also pick a Catastrophic plan. It has a low monthly premium and a very high deductible. It covers at least 3 primary care visits a year before you meet the deductible. But the IRS says you can't use the tax credit on a Catastrophic plan.

If your income is above the limit, you can still buy a Marketplace plan at full price. Some people also look at private plans sold outside HealthCare.gov, which don't come with the tax credit. Some private plans ask health questions, and approval is not guaranteed. Some may not cover care for health problems you had before you enrolled.

Option 3: COBRA
COBRA lets you keep your parent's job-based plan for a while. Federal law counts aging off a parent's plan as a COBRA event. In that case, COBRA can last up to 36 months.
- COBRA generally applies to plans from employers with 20 or more workers, the Department of Labor says. Some states, like Florida, have similar rules for smaller employers.
- You or your parent must tell the plan within 60 days after you age off. Don't wait for the plan to notice.
- Then you have 60 days to sign up. The clock starts when coverage ends or when you get the COBRA notice, whichever is later.
- You usually pay the full premium, and the plan can charge up to 102% of the cost.
COBRA keeps the same plan and benefits, but it can cost a lot. Compare it with a Marketplace plan. HealthCare.gov notes that dropping COBRA early on your own doesn't qualify you for a Special Enrollment Period.
Option 4: Medicaid
If your income is low, apply for Medicaid. You can apply any time of year. Rules vary by state. HealthCare.gov says some states have expanded Medicaid to cover all people with household incomes below a certain level, and others haven't.
One Marketplace application tells you if you qualify for Medicaid or for a Marketplace plan with a tax credit.
A timeline so you don't have a gap
- Two to three months before your birthday, ask your parent's plan for the exact date your coverage ends.
- Check if your own job offers a plan, and ask HR how long you have to sign up.
- In the 60 days before your coverage ends, compare Marketplace plans and enroll. That way your new plan can start on the first day of the month after the old one ends.
- If you're on a parent's Marketplace plan, enroll in your own plan during Open Enrollment.
