Medicaid or Marketplace? Which One to Apply For (2026 Open Enrollment)
Marketplace open enrollment runs November 1 through January 15, and every year millions of people shop for a plan on HealthCare.gov without realizing they qualify for Medicaid instead, which is free, has no deductible, and can be joined any day of the year. The dividing line is 138% of the federal poverty level in the 40 expansion states and DC: below it you belong in Medicaid, above it the Marketplace with subsidies is usually the better and only option. Here is how to tell which side you are on, what happens in the ten non-expansion states, and the mistakes that cost people real money every enrollment season.
The quick decision table
| Your situation (2026) | Where you belong | What it costs |
|---|---|---|
| Income under 138% FPL ($1,835/mo single, $3,142 family of 3), expansion state | Medicaid | Free or near-free; no deductible |
| Income 138%–250% FPL | Marketplace, silver plan | Often $0–$80/month after subsidy, reduced deductibles |
| Income 250%–400%+ FPL | Marketplace | Subsidized premium, standard deductibles |
| Under 100% FPL in a non-expansion state, no minor children | Coverage gap: no Medicaid, no subsidy | See the gap section below |
| Pregnant, or children in the household | Medicaid/CHIP first at much higher limits | Free; kids often qualify even when parents do not |
Five differences that matter more than the premium
- Enrollment window: Medicaid is open 365 days a year; the Marketplace only during open enrollment (Nov 1 – Jan 15) or within 60 days of a qualifying event like losing other coverage.
- Deductibles: Medicaid has none; a benchmark Marketplace plan carries a deductible that can run into thousands unless cost-sharing reductions apply.
- Retroactive coverage: Medicaid can pay bills from up to three months before you applied; Marketplace coverage never starts before your effective date.
- Monthly reporting: Medicaid uses current monthly income; the Marketplace uses your estimated annual income. A seasonal worker can legitimately qualify for Medicaid in lean months and subsidies for the year.
- Networks: Marketplace plans often have broader private-doctor networks; Medicaid networks lean on community clinics and health centers. If keeping a specific specialist matters, check both directories before deciding anything.
You cannot have subsidies if you qualify for Medicaid
The systems are designed as a handoff, not a choice. When you apply on HealthCare.gov with income under your state's Medicaid line, the application does not offer you subsidies; it forwards your file to the state Medicaid agency. People who want a "better" private plan and try to refuse Medicaid discover they would pay the full unsubsidized premium, often $400–$600 a month. The reverse is also true: if the Marketplace estimates you are Medicaid-eligible but the state denies you, take that denial letter back to the Marketplace; it unlocks your subsidy.
The non-expansion states and the coverage gap
In Texas, Florida, Georgia, Tennessee, Mississippi, Alabama, South Carolina, Kansas, Wyoming and Wisconsin*, adults without minor children generally cannot get Medicaid at any income. Marketplace subsidies only begin at 100% FPL ($1,330/month for one). Below that line sits the coverage gap. If you are in it:
- Project your annual income honestly but completely: subsidy eligibility uses expected annual income; counting seasonal work, gig income and expected raises can legitimately lift a projection above 100% and unlock full subsidies. Underestimating costs you coverage.
- Check categorical doors: pregnancy, a disability application, or becoming a caretaker of a minor each opens Medicaid even in these states.
- Use FQHCs: community health centers charge sliding-scale fees regardless of insurance; find one at findahealthcenter.hrsa.gov.
*Wisconsin is the exception that proves the rule: it covers all adults to 100% FPL, so it has no gap despite not expanding.
Mixed households are normal
One family often ends up in three programs at once, and that is fine: kids on CHIP, a pregnant spouse on Medicaid, the other parent on a subsidized silver plan. The Marketplace application sorts each member automatically. Never decline to apply because "we make too much"; the children's limits run roughly twice the adult limits in most states, as shown on each state page under Medicaid by state.
Mid-year moves between the two
Income changes move you across the 138% line, and both directions have a safety net. Losing Medicaid after a raise opens a 60-day Marketplace window with no gap if you act before the end date; the playbook is in what to do after a raise. Income dropping below the line mid-year lets you leave your Marketplace plan for Medicaid any day; just report to both sides so you are not double-covered and double-billed.
What to do next
- Compute your household's monthly gross income and compare it to the 138% line for your household size in the calculator.
- Below the line in an expansion state: apply directly with your state agency today; do not wait for open enrollment.
- Above the line: use HealthCare.gov between November 1 and January 15, pick silver if you are under 250% FPL, and enroll by December 15 for January 1 coverage.
- In a non-expansion state under 100% FPL: build your annual income projection carefully, screen the categorical doors, and locate your nearest FQHC either way.
- Whatever you choose, report income changes promptly; the handoff between the two systems only works when both sides know your current number.
