Family health insurance covers you, your spouse and your children on one plan or several. For Marketplace savings, your “family” is your tax household, and 2027 tax credits depend on its size and income. No one on an ACA family plan pays more than $12,000 for in-network care in 2027, and the whole family no more than $24,000.
Updated October 2026 for the 2027 plan year
Key facts (2027 plan year)
- Your Marketplace household is usually the tax filer, a spouse and tax dependents, even those who don’t need coverage (HealthCare.gov).
- Married couples must generally file jointly to get a premium tax credit; certain victims of domestic abuse or spousal abandonment are the exception (IRS).
- Since the “family glitch” fix, job-based coverage for family members is judged on the cost of family coverage, not employee-only coverage (IRS T.D. 9968).
- For 2027, job-based coverage is unaffordable if it costs more than 10.22% of household income (HealthCare.gov).
- Children can stay on a parent’s Marketplace plan through December 31 of the year they turn 26 (HealthCare.gov).
- The 2027 ACA out-of-pocket maximum is $24,000 for a family plan and $12,000 per person (CMS 2027 payment notice).
- Premium tax credits stop above 400% of the federal poverty level: $132,000 for a family of four for 2027 coverage (2026 HHS poverty guidelines).

What is family health insurance?
Family health insurance is coverage for two or more related people, usually a parent or couple plus their children. It can be one policy that lists everyone, or several plans that together cover the whole household.
In the individual market, a family plan is still priced person by person. The Centers for Medicare & Medicaid Services (CMS) lets insurers set Affordable Care Act (ACA) premiums only by location, age, tobacco use, plan category and how many people are covered (HealthCare.gov). Health history and sex can’t change the price.
Every ACA family plan covers the 10 essential health benefits, including pregnancy, maternity and newborn care and pediatric services (HealthCare.gov). That matters for families more than almost anyone.
What are your family coverage options?
Most families get coverage from a job, the ACA Marketplace, Medicaid or CHIP, or a combination. The best fit often mixes sources, such as a parent on a job plan and children on CHIP, because each person is checked for each program separately.
| Option | Best for | Savings available | When you can enroll |
|---|---|---|---|
| Job-based family plan | Families with an affordable employer offer | Employer pays part of the premium | Employer’s open season or a qualifying event |
| Marketplace family plan | Self-employed, small business and early-retiree families | Premium tax credit at 100%–400% FPL; cost-sharing reductions at or below 250% FPL | Nov 1, 2026 – Jan 15, 2027, or a Special Enrollment Period |
| Medicaid and CHIP | Lower-income families, children and pregnant women | Low or no cost, set by your state | Any time of year |
| Mixed coverage | Families where members qualify for different programs | Each person gets the help they qualify for | Depends on each program |
| Short-term plan | Rarely right for families | None | Any time, where state law allows |
Short-term plans are a poor fit for most families. They can exclude pre-existing conditions and rarely cover maternity care. Read our short-term health insurance guide before you consider one. If you would buy on your own, our individual health insurance guide explains on- and off-exchange plans.
Who counts in your household for subsidies?
For Marketplace savings, your household is the people on your federal tax return: you, your spouse if you are married, and your tax dependents. Everyone in that tax household counts toward household size and income, even a member who already has other coverage.
HealthCare.gov says to leave out roommates and people you only live with, unless they are your spouse or tax dependent (household rules). An unmarried partner who files separately is usually a separate household.
Household size sets your poverty-level line. For 2027 coverage, the Marketplace uses the 2026 HHS poverty guidelines for the 48 contiguous states and DC:
| Household size | 100% FPL | 138% FPL (Medicaid expansion) | 400% FPL (tax credit limit) |
|---|---|---|---|
| 2 | $21,640 | $29,863 | $86,560 |
| 3 | $27,320 | $37,702 | $109,280 |
| 4 | $33,000 | $45,540 | $132,000 |
| Each extra person | +$5,680 | Scales with household size | |
Alaska and Hawaii use higher guidelines; the full chart is in our federal poverty level 2026 guide. To see what a family at your income pays for the benchmark silver plan, see 2027 health insurance subsidies.
Married and filing separately? You generally can’t get a premium tax credit. The IRS allows an exception for certain victims of domestic abuse and spousal abandonment.
What was the family glitch, and how was it fixed?
The family glitch was a rule that judged a family’s job-based coverage only by what the worker paid for employee-only coverage. If that was affordable, the spouse and children were blocked from Marketplace tax credits, even when family coverage cost far more.
Final IRS regulations (T.D. 9968), effective December 12, 2022, changed that. Affordability for family members is now based on what the employee pays to cover the employee and those family members (Internal Revenue Bulletin 2022-45).
For 2027, a job-based plan is unaffordable if the required contribution is more than 10.22% of household income. The worker’s own eligibility is still judged on employee-only coverage. So a common result is a split: the worker stays on the job plan, and the spouse and children move to a subsidized Marketplace plan.
Run the numbers both ways. A split family can save on premiums but may face two deductibles. Compare the total yearly cost of one job-based family plan against the split.

Can kids be on CHIP while parents buy a Marketplace plan?
Yes. Children often qualify for Medicaid or the Children’s Health Insurance Program (CHIP) at incomes where their parents only qualify for Marketplace tax credits. When that happens, the children enroll in Medicaid or CHIP and the parents buy a Marketplace plan.
HealthCare.gov notes that when anyone in your household looks eligible for Medicaid or CHIP, the application is sent to your state agency. You can apply for Medicaid and CHIP any time of year. A child who qualifies for Medicaid or CHIP generally can’t get a tax credit for a Marketplace plan instead.
Apply for the whole household on one application, even if you think some members won’t qualify. For state program names and income limits for children, see health insurance for kids.
Can my children stay on my plan until 26?
Yes. Children can stay on a parent’s plan until age 26, whether they are married, living away from home, in school or financially independent. On a Marketplace plan, coverage lasts through December 31 of the year they turn 26.
HealthCare.gov confirms these rules for both job-based and Marketplace plans (young adults under 26). Job-based plans set their own end date after the 26th birthday, so check with the plan. Aging off a parent’s plan opens a Special Enrollment Period for the young adult’s own coverage.
One detail matters for subsidies. If your adult child files their own tax return and isn’t your dependent, they are a separate household. They may qualify for their own tax credit on their own income.
How do family deductibles and out-of-pocket maximums work?
A family plan has an individual amount for each person and a family amount for everyone combined. For 2027, no ACA plan can make one person pay more than $12,000 for in-network covered care, and no family pays more than $24,000 in total.
Embedded vs. aggregate
With an embedded deductible, each person has their own deductible inside the family one. When one child meets theirs, the plan starts sharing that child’s costs. With an aggregate deductible, the plan shares costs only after the whole family total is met.
The out-of-pocket maximum is always embedded at the self-only limit. In 2015 CMS clarified that the self-only limit applies to each individual, even on family coverage.
| Limit | Per person on a family plan | Whole family |
|---|---|---|
| Out-of-pocket maximum (ACA cap) | No more than $12,000 | No more than $24,000 |
| Deductible | Set by the plan; embedded or aggregate | Set by the plan |
| Premiums | Never count toward either limit | Never count toward either limit |

How to choose a family health insurance plan
Choose a family plan on total yearly cost for your real family, not the lowest premium. Families with young children, a pregnancy or ongoing care often do better with a lower deductible, even at a higher monthly premium.
- Check every person for every program: job offers, Medicaid, CHIP and tax credits.
- List your pediatrician, OB-GYN, specialists and hospitals, and check each network. See HMO vs. PPO vs. EPO vs. POS.
- Check each prescription on the plan’s drug list.
- Look for an embedded deductible if one person uses most of the care.
- Compare at least two metal levels. If your income is at or below 250% FPL, look hard at Silver for cost-sharing reductions. Our metal tier guide explains why.
- Get side-by-side quotes for your exact ZIP code. Our health insurance quotes guide has a checklist.
Premiums are rising again. A KFF review found insurers proposed a median 15% increase for 2027, so compare plans before you renew. More tips are in how to choose a health plan.

Frequently asked questions
How do I get family health insurance if my employer only pays for me?
Check whether family coverage through the job costs more than 10.22% of household income for 2027. If it does, your spouse and children may qualify for Marketplace tax credits under the family glitch fix, while you stay on the job plan.
Who is included in a family health insurance plan?
Usually the policyholder, a spouse and children under 26. For Marketplace savings, your household is your tax filer, spouse and tax dependents, even if some of them don’t need coverage.
What is the family out-of-pocket maximum for 2027?
No ACA family plan can charge more than $24,000 for in-network covered care in 2027, and no one person on it pays more than $12,000. Premiums don’t count toward these limits.
Can my children have CHIP while I have a Marketplace plan?
Yes. Children often qualify for Medicaid or CHIP at incomes where parents qualify only for Marketplace tax credits. Apply for the whole household on one application and each person is checked separately.
When can I add a baby or spouse to my family plan?
Birth, adoption and marriage are qualifying life events that open a Special Enrollment Period, usually 60 days. Otherwise, you can change your family plan during Open Enrollment, November 1, 2026 to January 15, 2027 on HealthCare.gov.
Do we have to be married to get a family plan with tax credits?
Married couples generally must file jointly to get a tax credit. Unmarried partners are usually separate tax households, so each applies on their own income, with children counted in the household of the parent who claims them.
