How to Apply for Medicaid in Any State in 2026: Why Your State Decides Before Your Income Does

Whether you qualify for Medicaid in 2026 depends less on how much you earn than on which state you live in: the 41 states (including DC) that expanded Medicaid use one clean income line, while the 10 that didn’t leave a coverage gap where earning less can leave you with nothing 1. So the first step in applying isn’t gathering documents — it’s finding out which kind of state you’re in.

The first question isn’t your income — it’s your state

Before you gather a single pay stub, find out whether your state expanded Medicaid, because that one fact — not your income — decides which set of rules even applies to you. Two callers with the same paycheck and the same household can get opposite answers: one lives in a state that expanded, qualifies, and enrolls; the other lives across the state line in a holdout state and is told no. Nothing about their money is different. Only their address is.

That is why the application steps barely matter at the start. They are nearly identical everywhere. The variable that decides the outcome is your state’s expansion status.

As of mid-2026, 41 states including DC have adopted Medicaid expansion and 10 have not — and that count can change, so treat it as a snapshot rather than a permanent rule 1. The 10 holdouts are Alabama, Florida, Georgia, Kansas, Mississippi, South Carolina, Tennessee, Texas, Wisconsin, and Wyoming 1.

The fastest way to find your bucket and your state’s actual income line is to run the Medicaid eligibility calculator, which applies your own state’s rules rather than a generic national figure.

If your state expanded: one clean line at about 138% of poverty

In the 41 states (plus DC) that expanded Medicaid, the rule is refreshingly simple — most adults aged 19 to 64 qualify if their income is at or below about 138% of the federal poverty level. There is one line, and you are either under it or over it.

That 138% comes from the law setting eligibility at 133% of the poverty level plus a 5-percentage-point income disregard, which works out to an effective 138% 2. Your income for this test follows a measure called MAGI — modified adjusted gross income.

MAGI is worth understanding once, because it decides everything. Wages, self-employment income, and Social Security benefits count toward it; Supplemental Security Income (SSI) does not 3. As a general rule, Medicaid looks at your current monthly income, while the marketplace projects your income for the whole year 3.

Picture a single adult working part-time near the poverty line in an expansion state. There is one income line, and one answer. What that line equals in dollars depends on your household size, your state, and which year’s poverty table is in force — which is exactly why this article doesn’t print a number. Let the Medicaid eligibility calculator apply the correct figure for you.

If your state didn’t expand: the gap where earning less can hurt you

In the 10 states that didn’t expand, there is no clean income line — childless adults are generally shut out entirely, parents qualify only far below the poverty line, and a structural “coverage gap” means earning less can leave you with nothing while earning more can unlock help. This is the part most “how to apply” guides never mention, and it is the part that matters most.

Start with two neighbors in a holdout state. One is a parent earning just below the poverty line; that parent gets neither Medicaid nor marketplace help. The other earns a few thousand dollars more, crosses 100% of the poverty level, and suddenly qualifies for heavily subsidized marketplace coverage. The cliff runs backwards.

Here is why. In non-expansion states the Medicaid floor is fragmented: childless adults generally do not qualify at any income (Wisconsin is the lone exception), and parent income limits sit well below the poverty line — often well under half of it 4. Those parent percentages vary by state and category, so treat any single figure as an illustrative range, not a current universal number, and check your own state’s limit with the calculator 4.

The coverage gap is the space this creates: your income is above your state’s tiny Medicaid limit but below 100% of the poverty level, which means no Medicaid and no marketplace subsidy, because subsidies don’t start until you reach 100% 5. KFF’s latest estimate, based on 2023 data, puts roughly 1.4 million people in this gap, concentrated in the South 5.

This gap is structural and still open in 2026, and no temporary federal policy closes it 6. Reaching 100% of the poverty level is what opens marketplace premium tax credits; below that line, those credits are out of reach 6. That is the inversion — the reason earning a little more can help while earning less leaves you stranded.

Non-expansion does not always mean zero coverage, though. Georgia runs a limited “Pathways to Coverage” program with work requirements, and Wisconsin’s Section 1115 waiver covers adults up to 100% of the poverty level 1. Because Wisconsin’s Medicaid reaches exactly where marketplace subsidies begin, Wisconsin is the one non-expansion state with no coverage gap 7. That single exception is the whole lesson: the answer is “know your state,” not “know the national number.”

How to actually apply — the part that’s the same everywhere

Once you know which bucket you’re in, applying is the easy part and it works the same way in every state: you file through HealthCare.gov or directly with your state Medicaid agency, any time of year. There are two doors, and both lead to the same place 8.

You can apply at HealthCare.gov, which forwards likely qualifiers to your state agency, or you can go straight to your state Medicaid or CHIP agency — online, by phone, by mail, or in person 8.

Unlike the ACA marketplace, Medicaid and CHIP have no open-enrollment window. You can apply any time of year, and coverage can begin immediately once you qualify 8. That is the single most useful difference to remember: there is no deadline to miss.

What you’ll need is straightforward — proof of identity and proof of income, the same documents that establish your MAGI from above. After you submit, the agency reviews your application, contacts you, and starts your coverage as soon as it confirms you qualify 8. The hard part was figuring out your state’s line. This part is just paperwork.

If the calculator says you don’t qualify

If the calculator shows you above the Medicaid line or stuck in the coverage gap, you still have a next step — and which one depends on which side of 100% of poverty you land on.

If you’re just above the Medicaid line, or at or above 100% of poverty in a holdout state, the marketplace with premium tax credits is your path. Compare it against Medicaid with the Medicaid vs. marketplace tool, and weigh specific plans with the health insurance comparison tool. One honest note: marketplace coverage got more expensive in 2026 because the enhanced premium tax credits expired at the end of 2025, which KFF reports raised what enrollees pay 6. The path still works; it just costs more than it did.

If you’re below 100% of poverty and in the gap, marketplace subsidies are out of reach 5. Your real options are community health centers and sliding-scale clinics, which charge based on what you can afford. The higher-earning neighbor goes to the marketplace; the gap-stuck neighbor goes to a community health center. Neither is left with nothing to do.

Run the Medicaid eligibility calculator now to see exactly where your household lands against your state’s line — and if you qualify, start your application the same day, because Medicaid has no enrollment window to wait for.
