Teenagers between 13 and 19 sit at a coverage crossroads that few parents plan for until it arrives. CHIP and Medicaid cover the large majority of low- and moderate-income adolescents through age 18, but CHIP eligibility ends abruptly at the 19th birthday in nearly every state, even mid-plan-year. A parent's employer plan can carry a teenage dependent all the way to age 26 under federal law, which makes it the most stable option for families who have it. High schoolers, working teens with a first part-time job, and teenagers about to age out of CHIP each face a different set of decisions, and the wrong assumption can leave a household paying full price or, worse, leave a teen briefly uninsured.
Working teens raise a question almost every parent asks eventually: does a summer job or part-time paycheck threaten the family's Medicaid or CHIP eligibility? Usually not. A teenager's earned income is generally excluded from household MAGI for Medicaid, CHIP, and Premium Tax Credit purposes unless the teen is required to file a separate federal tax return and claims the income independently. Adolescents managing a chronic condition, mental health needs, or reproductive health care also have confidentiality questions that a parent's employer plan does not always answer cleanly, since claims still generate an Explanation of Benefits sent to the policyholder. The CHIP eligibility by state guide covers the exact income cutoff where a teenager lives, and turning 26 and losing coverage explains what happens once a teenage dependent eventually ages off a parent's plan.
Your 4 Real Options
Available options| Option | Best for | Typical 2026 cost |
|---|
| Parent's employer plan (dependent coverage) | Teenagers with an employed parent; covers to age 26 | Often $0 to $400/month added to family premium |
| CHIP (Children's Health Insurance Program) | Teenagers under 19 in moderate-income families | $0 to $50/month; low copays |
| Medicaid for teenagers | Lower-income households (up to 138% FPL or higher state thresholds) | $0 premiums; minimal or no copays |
| ACA Marketplace family plan with Premium Tax Credit | Families above the CHIP ceiling, self-employed parents, or no employer plan | $0 to $800/month after PTC |
CHIP eligibility for teenagers ends automatically at age 19 in nearly every state. All four options must cover ACA-required preventive care, including adolescent depression screening and vaccines, with no cost sharing. The 2026 ACA Marketplace out-of-pocket maximum is $10,600 individual / $21,200 family.

Option 1: Parent's Employer Plan (Dependent Coverage)
ACA Section 2714 requires employer-sponsored health plans that offer dependent coverage to keep teenagers and young adults enrolled until age 26, regardless of student enrollment, marital status, or financial independence. Most teenagers stay covered this way by default once a parent has job-based insurance, and no separate application is required beyond the plan's annual open enrollment paperwork. A teenage dependent added mid-year, for example after a custody change following a divorce, typically has 30 to 60 days from the qualifying event to enroll under the plan's own rules.
The tradeoff for many families is cost and network fit. Adding a teenager to a parent's plan can raise the family premium by $100 to $400 per month in 2026, and an out-of-state college-bound teenager may find a parent's HMO network does not reach the new campus. High schoolers who need care outside the plan's home region, or teens on travel sports teams, should confirm out-of-network emergency coverage before relying solely on a parent's plan.
Option 2: CHIP (Children's Health Insurance Program)
CHIP fills the income gap between Medicaid and private insurance for teenagers whose family earns too much for Medicaid but not enough to comfortably afford marketplace premiums. Every state covers CHIP-eligible adolescents from birth through the 19th birthday, and coverage ends automatically once a teenager turns 19, even mid-plan-year. In 2026, CHIP income ceilings typically run 200% to 317% of the Federal Poverty Level (FPL) depending on the state, meaning a family of four earning $66,000 or more can still qualify. Premiums are capped federally at 5% of household income and usually run $0 to $50 per month, with copays of $1 to $5.
CHIP is state-administered and goes by different brand names: Florida KidCare, Kentucky's KCHIP, Illinois' AllKids, and Texas' Children's Medicaid STAR program all serve the same federal CHIP population. Under the CAA 2023 continuous eligibility mandate, a teenager enrolled in CHIP keeps coverage for a full 12 months even if family income rises mid-year, but that protection stops the moment the teenager turns 19. Parents should start planning the transition to Medicaid, a parent's employer plan, or a Marketplace plan at least 60 days before a teenager's 19th birthday.
Option 3: Medicaid for Teenagers
Medicaid covers teenagers in families at or below 138% of the 2026 Federal Poverty Level in the 40 expansion states plus D.C., and many states set separate, higher thresholds specifically for minor dependents. In 2026, 138% FPL is $22,025 for a household of one and $45,540 for a household of four. Medicaid for teenagers includes the EPSDT (Early and Periodic Screening, Diagnostic, and Treatment) benefit, covering every medically necessary service for enrollees under 21, including mental health care, substance-use treatment, dental, vision, and reproductive health services, generally with stronger confidentiality protections for adolescents than a parent's employer plan offers through its Explanation of Benefits mailings.
Option 4: ACA Marketplace Family Plan with Premium Tax Credit
Families with a teenager whose household income sits above the CHIP ceiling but below 400% of the 2026 FPL ($132,000 for a family of four) may qualify for the Premium Tax Credit (PTC) on a Marketplace family plan. The PTC calculation still counts a teenage dependent in household size even when the teenager is separately enrolled in CHIP or Medicaid, which often increases the subsidy available for the parents' portion of the plan. Families reconcile the PTC using Form 1095-A at tax time. The 2026 subsidy cliff returned January 1, 2026 after enhanced Premium Tax Credits from ARPA and the IRA expired, so subsidies phase down approaching 400% FPL and stop entirely at 400%.
Traps That Cost Teens Thousands
Families covering teenagers run into a specific set of avoidable mistakes:
Common traps for Teens| Trap | Why to avoid |
|---|
| Assuming a teenager's part-time job disqualifies the family | A working teen's earnings from a part-time or summer job generally do not count toward household MAGI for Medicaid, CHIP, or Premium Tax Credit purposes unless the teenager must file a separate federal tax return and claims the income independently. Most working teens earn well under that filing threshold. |
| Missing the CHIP age-out cliff at 19 | CHIP coverage for teenagers ends automatically at the 19th birthday in nearly every state, regardless of the CAA 2023 continuous eligibility rule. Screen for Medicaid, a parent's employer plan, or a Marketplace Special Enrollment Period at least 60 days before the teenager turns 19. |
| Assuming free preventive and mental health screenings aren't covered | ACA Section 2713 requires every Marketplace, employer, and Medicaid plan to cover USPSTF grade A and B preventive services for adolescents with no cost sharing, including annual depression screening for ages 12 to 18, HPV and meningococcal vaccines, and confidential substance-use screening. |
| Overlooking the Explanation of Benefits confidentiality gap | A minor dependent on a parent's employer plan or Marketplace family plan often has sensitive care, mental health counseling, reproductive health visits, or substance-use treatment, summarized on an Explanation of Benefits mailed to the primary policyholder. Confidentiality protections vary by state and by carrier, so ask directly. |
If a teenager's eligibility is unclear, apply anyway. Medicaid and CHIP applications are free, take about 15 minutes online, and a determination does not affect a family's credit or immigration record.

Medicaid and CHIP income limits for teenagers by household size in 2026
Teenage dependents qualify under the same federal income thresholds as younger children, with many states setting higher child-specific Medicaid ceilings and CHIP ceilings that reach 250%, 300%, or 317% FPL. The table below shows the 2026 federal reference points at 138% FPL (the Medicaid expansion floor), 200% FPL (the federal CHIP minimum floor), and 400% FPL (the Premium Tax Credit subsidy cliff). Use it to gauge whether Medicaid or CHIP is likely available for a teenager, then verify the exact state limit at InsureKidsNow.gov, since CHIP ceilings for adolescents vary widely by state.
2026 Medicaid and CHIP income reference thresholds for teenagers by household size (48 states + D.C.)| Household size | 138% FPL (2026) Medicaid expansion floor | 200% FPL (2026) CHIP federal minimum floor | 400% FPL (2026) ACA subsidy cliff |
|---|
| 1 | $22,025 | $31,920 | $63,840 |
| 2 | $29,863 | $43,280 | $86,560 |

| Each additional person | + $7,838 | + $11,360 | + $22,720 |
138% FPL = 2026 FPL x 1.38. 200% FPL = 2026 FPL x 2.00. 400% FPL = 2026 FPL x 4.00. Per-person increment at the 2026 base FPL is $5,680. A teenager's own part-time earnings are typically excluded from these household calculations. Source: HHS ASPE 2026 poverty guidelines.

Premium Tax Credit (PTC) eligibility for families with teenagers in 2026
Families with a teenage dependent whose income lands above the CHIP ceiling but under 400% of the 2026 FPL qualify for the Premium Tax Credit (PTC) on a Marketplace family plan. For a family of four, 400% FPL in 2026 is $132,000 in annual MAGI. Subsidies phase down as income approaches that ceiling and stop entirely at 400% FPL, a reversal from 2021 through 2025 when enhanced PTCs under the American Rescue Plan Act and Inflation Reduction Act extended eligibility above 400% FPL. Those enhanced credits expired January 1, 2026, so families budgeting for a high schooler's coverage should model the 2026 subsidy structure, not the 2025 one.
One nuance matters for families whose teenager is enrolled in CHIP or Medicaid while the parents shop the Marketplace: the household size used to calculate the PTC still includes the teenager, even though the teen sits on a different program. This lowers the calculated required premium contribution and often raises the subsidy for the adult-only Marketplace plan. Families reconcile the PTC with the IRS using Form 1095-A at tax time, and any advance credit paid on behalf of a household with a teenager must match the household size reported at enrollment.
CHIP age-out at 19: what happens to a teenager's coverage in 2026
CHIP is built for adolescents, not adults. Nearly every state ends CHIP eligibility the moment a teenager turns 19, regardless of the CAA 2023 rule that otherwise locks in 12 months of continuous eligibility for younger children. A family should start planning the transition at least 60 days before a teenager's 19th birthday, because the loss of CHIP itself is a qualifying life event that opens a 60-day Marketplace Special Enrollment Period.
- Check Medicaid first: some teenagers who aged out of CHIP still qualify for Medicaid as young adults if household income falls under the state's adult threshold.
- Add the teenager to a parent's employer plan if available; federal law guarantees dependent coverage until age 26 regardless of the CHIP age-out.
- Enroll in a Marketplace plan through the 60-day Special Enrollment Period triggered by the loss of CHIP; Premium Tax Credits may apply if household income qualifies.
- For an 18- or 19-year-old who is independent, an individual Marketplace plan (with or without a subsidy) may be the right fit once CHIP ends.
HSA and HDHP fit for teenagers in 2026
A family enrolled in an HSA-qualified High-Deductible Health Plan (HDHP) can use the Health Savings Account (HSA) to pay for a teenager's qualified medical expenses tax-free, including copays, orthodontia, prescriptions, and mental health counseling. In 2026 the HDHP minimum deductible for family coverage is $3,400, the family HSA contribution limit is $8,750 (plus $1,000 catch-up if the account holder is 55 or older), and the HDHP family out-of-pocket maximum is $17,000. The HSA delivers a triple tax advantage: contributions are deductible above the line, growth is tax-free, and qualified withdrawals are tax-free.
A key nuance: a teenage dependent cannot open a personal HSA, because IRS rules bar anyone claimed as a tax dependent from being an HSA account holder. Funds stay in the parent's HSA and can still cover the teenager's expenses. A Flexible Spending Account (FSA) works differently: it is employer-only, requires no HDHP pairing, and its 2026 healthcare contribution limit is $3,400 per employee. Families whose teenager is on Medicaid or CHIP rather than an employer plan have no FSA access for that teen's expenses, since FSA is strictly employer-sponsored.
Form 7206 self-employment health insurance deduction: N/A for most teenagers in 2026
Form 7206 does not apply to most teenagers because most teenagers have no self-employment income to deduct against. A working teen with a traditional part-time or summer job receives a W-2 and is not eligible to claim the self-employed health insurance deduction. The rare exception is a working teen who earns 1099 income from gig apps, content creation, or freelance work; if that teen has net self-employment earnings and pays their own premiums, Form 7206 could theoretically apply. In practice, very few teenagers clear the income and premium thresholds that would make the deduction meaningful, and most teens remain covered as dependents on a parent's plan, CHIP, or Medicaid rather than buying individual coverage.
Catastrophic plan eligibility for teenagers in 2026
Catastrophic Marketplace plans are restricted under ACA rules to adults under age 30 or anyone who holds a hardship exemption. A minor dependent under 18 cannot independently enroll in any individual Marketplace plan, catastrophic or otherwise, because signing a Marketplace policy as the primary subscriber requires legal adult status in every state. Catastrophic plans become relevant only for an 18- or 19-year-old who has aged out of CHIP and enrolls independently; for that narrow group, the 2026 catastrophic plan deductible is $10,600, equal to the ACA out-of-pocket maximum, meaning nearly all medical costs fall on the enrollee until that cap is reached. For a typical teenager still under a parent's household, Medicaid, CHIP, or a standard Bronze or Silver family plan is almost always the better fit.
Marketplace Special Enrollment Period (SEP) triggers for teenagers and how to enroll
Families with a teenager can access Marketplace coverage outside the November-to-January open enrollment window through a Special Enrollment Period (SEP), typically a 60-day window from the qualifying event. Medicaid and CHIP, by contrast, accept applications for teenagers year-round with no enrollment window, making them the coverage of last resort for an uninsured adolescent at any point in the year.
To enroll a teenager, start at InsureKidsNow.gov or HealthCare.gov and select a state; both route the application to the correct program. Gather documents needed: proof of the teenager's age and identity, proof of state residency, proof of household income (pay stubs, tax return, or W-2s), Social Security numbers for household members, and immigration documents if applicable. Submit online, by phone, by mail, or in person; online is typically fastest. Most states return an eligibility determination for a teenager within 2 to 5 business days. Common denial reasons include income above the state's CHIP ceiling, the teenager already being covered elsewhere, incomplete documentation, or a mismatch in household composition between the application and state records.
- Loss of CHIP at age 19: 60-day SEP window to enroll a young adult in a Marketplace plan
- Loss of other coverage (parent's employer plan ends, COBRA exhausted): 60-day SEP window
- Moving to a new state: Medicaid and CHIP eligibility does not transfer; re-apply in the new state for the teenager
- Household income change that causes a teenager to lose or gain Medicaid or CHIP eligibility: 60-day SEP window
- Marriage or divorce affecting household composition: 60-day SEP window
- Medicaid and CHIP applications for teenagers accepted year-round with no open enrollment restriction
Frequently Asked Questions
What's the cheapest health insurance option for teenagers in 2026?
For most families, Medicaid or CHIP is the cheapest option for a teenager in 2026. Medicaid is free for families up to 138% FPL in expansion states, and CHIP typically runs $0 to $50 per month for families up to roughly 200% to 317% FPL depending on the state. A family of four earning up to $66,000 (200% FPL) likely qualifies for CHIP in most states. If the family earns above the CHIP ceiling, a parent's employer plan or a subsidized Marketplace family plan is usually next cheapest. Use the screener or InsureKidsNow.gov to check exact state limits.
Do teenagers qualify for the Premium Tax Credit?
The Premium Tax Credit (PTC) applies to a family's Marketplace plan, not to a teenager individually. If household MAGI is between 100% and 400% FPL in 2026, the PTC reduces the family's monthly premium. A teenager enrolled in CHIP or Medicaid is excluded from the Marketplace plan itself but is still counted in household size for the PTC calculation, which can raise the subsidy for the parents' coverage. Families reconcile the PTC using Form 1095-A at tax time. The subsidy cliff returned January 1, 2026, so families at or above 400% FPL receive no subsidy.
Can a family deduct a teenager's health insurance premiums on taxes?
Form 7206, the self-employed health insurance deduction, does not apply to most teenagers because most teenagers have no self-employment income. A working teen with a W-2 job cannot claim it. The rare exception is a working teen with net 1099 self-employment earnings who pays their own premiums, though very few teenagers clear the thresholds that make the deduction meaningful. Adults claiming a teenage dependent generally deduct medical expenses, including the dependent's premiums, only through the itemized medical expense deduction on Schedule A, above 7.5% of AGI.
Can a teenager use an HSA?
A teenage dependent cannot open a personal HSA because IRS rules bar anyone claimed as a tax dependent from being an HSA account holder. But if the family has an HSA-qualified HDHP, the parent's HSA can still pay for the teenager's qualified medical expenses tax-free, including copays, orthodontia, and mental health counseling. In 2026 the family HSA contribution limit is $8,750 and the family HDHP minimum deductible is $3,400. A Flexible Spending Account (FSA) is a separate employer-only option that also covers a teenager's expenses but has no HDHP requirement.
What if the family makes too much for CHIP?
Families above the CHIP ceiling (typically 200% to 317% FPL depending on the state) but under 400% FPL usually still qualify for Premium Tax Credits on a Marketplace family plan covering the teenager. For a family of four, 400% FPL in 2026 is $132,000. Above that line, the subsidy cliff that returned January 1, 2026 means the family pays the full unsubsidized premium. A parent's employer plan, if available, is often cheaper than an unsubsidized Marketplace plan for a family above the cliff.
When can a teenager enroll in a Marketplace plan outside open enrollment?
A family can trigger a 60-day Special Enrollment Period (SEP) for a teenager through several events: loss of CHIP at age 19, loss of a parent's employer coverage, a household income change that affects Medicaid or CHIP eligibility, moving to a new state, or marriage or divorce affecting household composition. Medicaid and CHIP, unlike the Marketplace, accept applications for teenagers year-round with no enrollment window, so an uninsured teenager can apply for those programs at any time.
What happens to a teenager's CHIP coverage at age 19?
CHIP eligibility ends automatically at the 19th birthday in nearly every state, regardless of the CAA 2023 continuous eligibility rule that otherwise locks in 12 months of coverage. Losing CHIP is itself a qualifying event that opens a 60-day Marketplace Special Enrollment Period. Families should first check whether the newly-19 young adult still qualifies for Medicaid, then consider adding them to a parent's employer plan (guaranteed until 26 under federal law), or enrolling them independently on the Marketplace.
Can a teenager enroll in a catastrophic plan?
A minor teenager under 18 cannot independently enroll in any individual Marketplace plan, including catastrophic plans, because becoming the primary subscriber on a Marketplace policy requires legal adult status. Catastrophic plans become an option only for an 18- or 19-year-old who has aged out of CHIP and enrolls independently, since catastrophic eligibility is restricted to adults under 30 or hardship-exemption holders. For most teenagers still living in a parent's household, Medicaid, CHIP, or a standard family plan is the better fit.
