Who Qualifies for Obamacare in 2026? Full Eligibility Guide

Who qualifies for Obamacare: residency, immigration status, income ranges, Medicare exclusions, and special cases for immigrants and mixed-status families.

Last updated: May 11, 2026

If you are wondering whether you qualify for Obamacare, the short answer is probably yes. The longer answer depends on a handful of clean rules — and a few special cases that confuse people who try to figure it out alone. This guide walks through every category, with no jargon, so you can know in five minutes whether you can enroll and whether you will get help paying for it.

By the most recent count, 24 million Americans were enrolled in a Marketplace plan, according to the Centers for Medicare & Medicaid Services (CMS). About 90% of them received a subsidy. The rules below explain who is in that group, who is routed to Medicaid instead, and who is unfortunately left out.

The basic Obamacare eligibility checklist

To buy a plan through the Health Insurance Marketplace (HealthCare.gov or a state-run site), you must meet four requirements:

  1. Live in the United States. Any US state, DC, Puerto Rico (with caveats), or US territory with a Marketplace.
  2. Be a US citizen, US national, or lawfully present immigrant. More on this below — it is broader than people think.
  3. Not be currently incarcerated. Pretrial detention does not count; serving a sentence does.
  4. Not be enrolled in Medicare. Once you are on Part A or Part B, the Marketplace is no longer the right place for you.

That is the entire list. You do not need to be employed, you do not need to be married, and you do not need a minimum income. If you can check those four boxes, you can buy a plan.

Whether you qualify for a subsidy that lowers what you pay is a separate calculation, and that is where the income rules come in.

US residency: what counts and what does not

You must consider the United States your home. You do not need to be a permanent legal resident — even people on certain work visas, student visas, and humanitarian statuses qualify, as long as they are physically living in the US and plan to file federal taxes (or be claimed on someone else’s tax return).

Specifically:

  • All 50 states and DC are covered by either HealthCare.gov or a state-based Marketplace.
  • Puerto Rico has its own coverage system — Marketplace plans are not sold there in the same way.
  • US Virgin Islands, Guam, American Samoa, Northern Mariana Islands have their own arrangements.
  • People living abroad generally cannot buy Marketplace coverage; they need international or local coverage instead.

If you spend part of the year outside the US (snowbirds, business travel, family abroad), you usually still qualify as long as your tax home is in the US. Plans cover emergency care anywhere in the world but routine care outside your network’s US service area is generally not covered.

Citizenship and immigration status

This is where most of the confusion lives. The ACA was deliberately designed to cover lawfully present immigrants, not just citizens. The list of qualifying statuses is long.

Who qualifies as “lawfully present”

You are considered lawfully present if you have any of these statuses:

  • US citizen (born in the US, naturalized, or born abroad to US citizen parents)
  • US national (born in American Samoa or Swains Island)
  • Lawful Permanent Resident (green card holder)
  • Refugee, asylee, or person granted withholding of deportation
  • Cuban or Haitian entrant
  • Parolee (including humanitarian parole)
  • Conditional entrant (granted before 1980)
  • Victim of trafficking, domestic violence, or other serious crime (T-visa, U-visa, VAWA self-petitioner)
  • Special Immigrant Juvenile status
  • Individual with Temporary Protected Status (TPS)
  • Deferred Enforced Departure (DED) recipient
  • DACA recipient in most states for 2026 (rules have shifted; verify with an agent)
  • Member of a federally recognized Indian tribe or American Indian born in Canada
  • Holder of a valid non-immigrant visa in many work, student, and family categories
  • Applicant for several of the above, with employment authorization

Lawfully present immigrants qualify for Marketplace plans and subsidies on day one. There is no five-year waiting period like Medicaid has. This is one of the most underused benefits in the ACA.

Who does not qualify

Undocumented immigrants cannot enroll in Marketplace plans through the federal system. This includes people who entered without inspection, people who overstayed visas, and people with final orders of removal.

If you are undocumented, you still have options:

  • Federally Qualified Health Centers (FQHCs) provide primary care on a sliding scale regardless of status.
  • Emergency Medicaid covers life-threatening conditions in every state.
  • Several states (Covered California, Colorado, Washington, New York for some groups) have created their own coverage paths.
  • Off-Marketplace private plans are available but unsubsidized — expensive.

We have a detailed guide for this audience: Obamacare without an SSN covers ITIN applications, DACA, and mixed-status families in depth.

Mixed-status families

This is the most common situation and the most misunderstood. A mixed-status family means some members are eligible (US citizens, green card holders, etc.) and some are not.

The rule is simple: only the eligible members get enrolled, and the application data is confidential. Under ACA §1411(g) and longstanding federal policy, information collected by the Marketplace cannot be shared with immigration enforcement. The National Immigration Law Center (NILC) has documented this repeatedly. We will not pretend the political climate never matters, but the legal protections have held under multiple administrations.

If you are an undocumented parent applying on behalf of your US-citizen children, you do not need to provide your own SSN, citizenship status, or immigration documents. You list the children’s information, your household income, and the Marketplace enrolls the children only.

Income and household size

Income does not determine whether you can enroll. It determines what kind of help you get.

The system uses your Modified Adjusted Gross Income (MAGI) for the year you are buying coverage. It compares that number to the Federal Poverty Level (FPL) for your household size and applies different rules at different ranges.

For 2026 enrollment, expect approximate ranges like these (single person; family numbers are higher):

  • Under 138% FPL (~$20,800): Routed to Medicaid in expansion states. In non-expansion states, possible coverage gap.
  • 100% to 250% FPL (~$15,000 to $37,650): Premium tax credit plus cost-sharing reductions on Silver plans. The best deal in the entire system.
  • 250% to 400% FPL (~$37,650 to $60,240): Premium tax credit, smaller as income rises.
  • Over 400% FPL: Still eligible for premium tax credit under current rules if Marketplace premium would otherwise exceed 8.5% of income.

A few specifics:

  • Self-employment income counts after business deductions. If you are a 1099 worker, gig driver, or small business owner, you report net income.
  • Social Security benefits count, including the portion that is normally not taxable.
  • Alimony from divorces finalized before 2019 counts; alimony from divorces after 2018 does not.
  • Tax-exempt interest counts. Most other tax-free income (Roth IRA distributions, life insurance proceeds, child support) does not.

Read our detailed income limits guide for the full breakdown.

Medicare and Obamacare do not mix

Once you are enrolled in Medicare Part A or Part B, you are out of the Marketplace subsidy pool. Specifically:

  • You cannot receive a premium tax credit if you have Medicare.
  • You technically can buy a Marketplace plan without subsidies, but this is rarely a good idea.
  • You must disenroll from your Marketplace plan when Medicare starts, or you will lose subsidies and may owe money back at tax time.

If you are approaching 65, the right move is to switch from your Marketplace plan to Medicare during your Initial Enrollment Period (the 7-month window around your 65th birthday). A licensed agent who handles both can coordinate the transition.

If you are under 65 and on Medicare due to a disability or end-stage renal disease, the same rule applies — Medicare disqualifies you from Marketplace subsidies.

Incarceration

Federal rules say that people serving a sentence in a correctional facility cannot enroll in a Marketplace plan. The reasoning is that the facility is responsible for healthcare during the sentence.

Two important caveats:

  • Pretrial detention (held but not yet convicted) does not disqualify you. You remain technically eligible to enroll.
  • Release from incarceration is a qualifying life event. When you get out, you have a 60-day Special Enrollment Period to enroll, even if Open Enrollment is closed.

This matters for re-entry programs and for families helping a recently released loved one access healthcare quickly.

Employer coverage and the “affordability” rule

If your employer offers you health insurance, the rules get nuanced. You can still buy a Marketplace plan, but you may not qualify for a subsidy.

The test is whether your employer’s coverage is affordable and meets minimum value:

  • Affordable (for 2026) means the employee-only premium is 9.12% or less of your household income.
  • Minimum value means the plan pays at least 60% of expected healthcare costs.

If your employer’s plan meets both standards, you generally cannot get a Marketplace subsidy. If it fails either standard, you can.

The family glitch fix

For years, the “family glitch” said that affordability was tested on the employee-only premium even when the actual question was whether the employee could afford family coverage. The IRS fixed this in 2022.

Today, a family member can qualify for Marketplace subsidies if the family premium from the employer exceeds 9.12% of household income — even when the employee-only premium does not. This change opened the door for millions of dependents to get cheaper coverage.

If your spouse’s employer offers expensive family coverage, get a Marketplace quote for the rest of the family before just signing up at work.

Already have a job offer of coverage? A licensed agent can compare it to Marketplace plans free of charge.

Special cases worth knowing

A few situations come up often enough to mention:

  • College students under 26 can stay on a parent’s plan. After 26, they qualify for the Marketplace if they meet the standard requirements.
  • Self-employed people without employer coverage are excellent candidates for the Marketplace. Income flexibility makes subsidy planning easier.
  • Recent retirees between 60 and 64 often see the biggest savings — high subsidies due to age-based premiums and often modest retirement income.
  • Veterans with VA coverage can keep their VA care and add a Marketplace plan, though most do not need to. VA care satisfies the minimum coverage requirement.
  • Native Americans and Alaska Natives have special Marketplace rules including no-cost-sharing Zero Plans at certain income levels.
  • Dependents on a divorced parent’s plan can move to their own Marketplace plan during a Special Enrollment Period triggered by the divorce.

Frequently asked questions

Who qualifies for Obamacare in 2026?
You qualify to buy a Marketplace plan if you live in the United States, are a US citizen, US national, or lawfully present immigrant, are not currently incarcerated, and are not enrolled in Medicare. That is the entire eligibility checklist to enroll. Qualifying for a premium tax credit is a separate calculation based on household income and family size. Most US adults under 65 who are not on Medicare or employer coverage qualify to enroll, and the vast majority who do enroll also qualify for some level of subsidy. A licensed agent can confirm both your enrollment eligibility and your expected subsidy in a 10-minute call.
Do I need to be a US citizen to qualify?
No. You need to be lawfully present in the United States, which is a broader category than citizenship. Lawful permanent residents (green card holders), refugees, asylees, people granted withholding of deportation, Cuban and Haitian entrants, certain victims of trafficking and domestic violence, DACA recipients in most states for 2026, and dozens of other immigration statuses are all considered lawfully present and can buy Marketplace plans. Unlike Medicaid, there is no five-year waiting period for ACA subsidies — eligibility starts the day your lawful status begins.
Can undocumented immigrants get Obamacare?
Not on the federal Marketplace. Federal rules block undocumented immigrants from buying through HealthCare.gov, even with their own money. However, several states (California through Covered California, Colorado through Connect for Health Colorado, Washington through Cascade Care Savings, and others) have created separate coverage programs that include undocumented residents. Undocumented people can also access Federally Qualified Health Centers (FQHCs) on a sliding scale, Emergency Medicaid for life-threatening conditions, and off-Marketplace private plans paid out of pocket. Mixed-status families should always apply — only eligible members get enrolled.
What income do I need to qualify for Obamacare?
There is no minimum income required to buy a Marketplace plan, but income determines what kind of help you receive. If your household income is below 138% of the Federal Poverty Level (about $20,800 for a single person in 2026) and you live in a state that expanded Medicaid, you will be routed to Medicaid instead. If you are between 100% and 400% FPL, you almost certainly qualify for a premium tax credit. Through 2025 (and likely 2026), there is no upper income cliff — anyone whose Marketplace premium would exceed 8.5% of household income qualifies for some subsidy.
Can I qualify if I have a job that offers health insurance?
You can still buy a Marketplace plan, but you usually will not qualify for a subsidy if your employer's plan is considered affordable and meets minimum value standards. For 2026, employer coverage is considered affordable if the employee-only premium costs less than 9.12% of household income. The IRA fix to the family glitch means family members can now qualify for Marketplace subsidies even when employee coverage is affordable but family coverage is not. A licensed agent can run the math against your specific job offer for free.
Can I get Obamacare if I am on Medicare?
No. Once you are enrolled in Medicare Part A or Part B, you are no longer eligible to buy a Marketplace plan with a premium tax credit. You can technically buy a Marketplace plan without subsidies, but it is almost never a good idea — you would pay full sticker price for duplicate coverage. If you are turning 65 and currently have a Marketplace plan, you have a special enrollment period to switch to Medicare and should cancel your Marketplace coverage the month Medicare starts.
Can incarcerated people get Obamacare?
Not while incarcerated. If you are serving a sentence, you cannot enroll in a Marketplace plan. However, the moment you are released, you qualify for a Special Enrollment Period that gives you 60 days to enroll, even if it is not Open Enrollment season. People held in pretrial detention (not yet convicted) are technically still eligible to enroll, though it is rarely practical from inside a facility. Family members can apply on behalf of children left at home during a parent's incarceration.
Do retirees and people on COBRA qualify?
Yes, retirees under 65 who are not yet on Medicare are some of the biggest beneficiaries of Marketplace coverage — early retirement income often qualifies for excellent subsidies. People on COBRA can also drop their COBRA and switch to a Marketplace plan during Open Enrollment, or during a Special Enrollment Period if their COBRA is ending or no longer affordable. In most cases, Marketplace plans are far cheaper than COBRA. A licensed agent can compare both for you side by side.
