We cover Medicaid, the Affordable Care Act marketplace subsidies, and the Children’s Health Insurance Program (CHIP). We also explain how life events can open special enrollment periods and what documents you need to apply. By the end, you will know exactly where you stand and how to take the next step.

Who Qualifies for Low Income Health Insurance?

Eligibility for low income health insurance plans in the USA depends on several factors. The most important is your household income compared to the federal poverty level (FPL). The FPL is updated annually by the Department of Health and Human Services. For 2025 coverage (enrolling in late 2024), the FPL for a single person is around $15,060 in most states. For a family of four, it is about $31,200.

Income alone does not tell the full story. Your state of residence matters because some states expanded Medicaid under the Affordable Care Act while others did not. In expansion states, adults with income up to 138% of the FPL can qualify for Medicaid. In non-expansion states, eligibility is often limited to parents with very low income, pregnant women, or people with disabilities. Immigration status also plays a role: lawful permanent residents and citizens are generally eligible, while undocumented immigrants cannot receive federally funded coverage.

Other factors include age, disability status, and whether you have dependents. For example, children in low income households may qualify for CHIP even if their parents do not qualify for Medicaid. Pregnant women often have separate, more generous income limits. Seniors over 65 who have low income may qualify for both Medicare and Medicaid (dual eligible).

Income Limits and the Federal Poverty Level

The federal poverty level is the baseline for nearly all low income health insurance programs. The ACA marketplace uses a modified adjusted gross income (MAGI) to determine subsidy eligibility. If your MAGI falls between 100% and 400% of the FPL, you may qualify for premium tax credits that lower your monthly premium. If your income is below 100% of the FPL and you live in a state that did not expand Medicaid, you may fall into the coverage gap where you earn too little for marketplace subsidies but do not qualify for Medicaid.

To illustrate: a single person earning $20,000 per year (about 133% of the FPL) would likely qualify for both Medicaid in an expansion state or subsidized marketplace coverage in a non-expansion state. A family of four earning $45,000 (about 144% of the FPL) would also qualify for significant subsidies. The chart below shows general income tiers:

• Below 138% FPL: Likely eligible for Medicaid in expansion states (or CHIP for children).
• Between 138% and 250% FPL: Eligible for marketplace subsidies with lower deductibles and cost-sharing reductions.
• Between 250% and 400% FPL: Eligible for premium tax credits but fewer cost-sharing reductions.
• Above 400% FPL: No subsidy eligibility; must pay full price for marketplace plans.

These numbers change slightly each year. For the most accurate figures, use the official FPL table on Healthcare.gov or consult a licensed insurance broker. If you are unsure about your MAGI, remember that it includes wages, self-employment income, Social Security benefits, and some investment income, but it excludes certain items like child support and veterans’ benefits.

Medicaid: The Bedrock of Low Income Coverage

Medicaid is a joint federal and state program that provides free or very low cost health insurance to individuals and families with limited income. It covers doctor visits, hospital stays, preventive care, prescription drugs, mental health services, and long-term care. In states that expanded Medicaid under the ACA, eligibility extends to adults under 65 with income up to 138% of the FPL. In non-expansion states, eligibility is much narrower.

To apply for Medicaid, you can visit your state’s Medicaid agency website or use the Healthcare.gov application during open enrollment. You will need to provide proof of income, residency, and citizenship or lawful presence. Medicaid applications are accepted year-round because there is no limited enrollment period for this program. If you qualify, coverage can start as early as the month you apply.

One important nuance: some states have work requirements or premiums for certain Medicaid populations, though these are rare and often challenged in court. In general, traditional Medicaid has no premium and very low copayments. If you are approved, you will receive a Medicaid card and can choose a primary care provider from a network of doctors and hospitals that accept Medicaid.

For those who are dual eligible (qualify for both Medicare and Medicaid), the two programs coordinate to cover most medical costs. Medicare pays first for hospital and doctor services, and Medicaid covers premiums, deductibles, and services not covered by Medicare, such as dental and vision. This combination can eliminate out-of-pocket costs for low income seniors and people with disabilities.

ACA Marketplace Subsidies and Cost-Sharing Reductions

The Affordable Care Act marketplace offers two types of financial help for low and moderate income households: premium tax credits and cost-sharing reductions. Premium tax credits lower your monthly insurance premium. Cost-sharing reductions lower your deductibles, copayments, and out-of-pocket maximums when you choose a Silver plan.

To get these subsidies, you must enroll through the official marketplace (Healthcare.gov or a state-based exchange) during the annual open enrollment period, which typically runs from November 1 to January 15. If you miss this window, you may still qualify for a special enrollment period if you experience a qualifying life event such as losing job-based coverage, moving, getting married, or having a baby.

Income for subsidy purposes is based on your projected MAGI for the coverage year. If your actual income ends up lower or higher than you estimated, the subsidy will be reconciled when you file your taxes. If you underestimated your income, you may have to repay some of the subsidy. If you overestimated, you will get the difference as a tax credit. This is why it is important to report income changes during the year through your marketplace account.

For example, a 40-year-old single person earning $25,000 per year in Texas (a non-expansion state) would qualify for a premium tax credit that covers most of the cost of a Silver plan. After the subsidy, their monthly premium might be $50 to $100, depending on the plan and location. In New York (an expansion state), the same person might qualify for Medicaid instead, with no premium at all.

Special Enrollment Periods and Life Events

Life changes can open a special enrollment period (SEP) that allows you to enroll in a low income health insurance plan outside the regular open enrollment window. Common qualifying events include losing other health coverage (including job loss), moving to a new state, getting married or divorced, having a baby or adopting a child, and becoming a U.S. citizen.

You typically have 60 days before or after the event to enroll. For example, if you lose your job on March 15 and your employer coverage ends on March 31, you have until May 30 to choose a new plan through the marketplace. During this period, you can also apply for Medicaid or CHIP if your income has dropped. If you are unsure whether a specific event qualifies, call the marketplace call center or speak with a licensed broker.

Another important SEP is for individuals who were denied Medicaid because their state did not expand coverage. If you apply for Medicaid and are denied due to income (even if you are below the FPL), you may qualify for a SEP to enroll in a marketplace plan. This helps close the coverage gap in non-expansion states.

CHIP: Coverage for Children in Low Income Families

The Children’s Health Insurance Program (CHIP) provides low cost health coverage for children in families that earn too much to qualify for Medicaid but not enough to afford private insurance. CHIP covers routine checkups, immunizations, doctor visits, prescriptions, dental care, vision care, and emergency services. In many states, CHIP also covers pregnant women through a separate program.

Eligibility for CHIP varies by state, but most states cover children up to 200% to 300% of the FPL. For example, a family of three with an income of $50,000 per year might qualify for CHIP in a state with a 250% FPL limit. Premiums for CHIP are usually low (often $0 to $50 per month), and copayments are capped at 5% of family income.

To apply for CHIP, you can use the same application as Medicaid through your state’s health department or Healthcare.gov. If your child qualifies, coverage is available year-round with no enrollment deadline. Once enrolled, your child gets a medical home with a primary care doctor and access to specialists if needed.

Parents who are uninsured themselves can often apply for marketplace subsidies at the same time. In states that expanded Medicaid, parents may qualify for Medicaid along with their children. In non-expansion states, only the children might get coverage, leaving parents to rely on marketplace plans or employer coverage.

How to Apply and What Documents You Need

Applying for low income health insurance plans in the USA can be done online, by phone, by mail, or in person at a local community health center. The fastest method is through Healthcare.gov or your state’s exchange website. You will need to create an account, provide personal information for each household member, and estimate your income for the coming year.

Key documents to have ready include: Social Security numbers (or document numbers for lawful immigrants), employer and income information (pay stubs, W-2 forms, tax returns), policy numbers for any current health insurance, and information about job-based coverage offers. If you are applying for Medicaid, you may also need proof of citizenship or immigration status, such as a passport or green card.

Once you submit the application, the marketplace will determine your eligibility for Medicaid, CHIP, and premium tax credits. If you qualify for Medicaid or CHIP, your application is forwarded to your state agency, which will contact you to finalize enrollment. If you qualify for marketplace subsidies, you can browse plans and select one that fits your budget and healthcare needs.

If you need personalized help, consider speaking with a licensed broker or navigator. Many community organizations offer free assistance. For example, our team at NewHealthInsurance.com can help you compare plans and understand your options.

Frequently Asked Questions

What is the income limit for low income health insurance in 2025?

The limit depends on the program. For Medicaid in expansion states, the limit is 138% of the federal poverty level ($20,783 for a single person in 2025). For marketplace subsidies, the limit is 400% of the FPL ($60,240 for a single person). CHIP limits vary by state but are typically 200% to 300% of the FPL.

Can I get health insurance if my income is too low for subsidized marketplace plans?

Yes, if you live in a state that expanded Medicaid. If your state did not expand Medicaid and your income is below 100% of the FPL, you may fall into the coverage gap. In that case, you can look into community health centers, charity care, or short-term plans. However, short-term plans do not cover pre-existing conditions or essential health benefits.

Do I have to wait for open enrollment to apply for Medicaid?

No. Medicaid and CHIP accept applications year-round. You can apply at any time, and coverage can start as early as the month you apply. Marketplace subsidies, however, are generally available only during open enrollment or a special enrollment period.

What happens if I do not report a change in income?

If your income changes during the year and you do not update your marketplace application, your subsidy amount may be wrong. When you file taxes, the IRS will reconcile the subsidy you received with the amount you should have received. If you got too much subsidy, you may have to repay it (capped at certain limits). If you got too little, you get a tax credit.

For more information on how subsidies and tax credits interact with your coverage, see our article on AARP health insurance plans for ages 50-64 comprehensive guide.

Can undocumented immigrants get low income health insurance?

Undocumented immigrants are not eligible for Medicaid, CHIP, or marketplace subsidies. However, they may qualify for emergency Medicaid (which covers emergency medical care) or purchase a private plan outside the marketplace at full price. Some states offer state-funded programs for undocumented residents, but these are limited.

If you are a lawful permanent resident, you must typically wait 5 years after obtaining your green card before you can receive Medicaid, though some states waive this waiting period for children and pregnant women.
