Understanding Low-Income Health Insurance Plans
Low-income health insurance plans are government-funded or subsidized programs designed to make healthcare affordable for individuals and families with limited financial resources. The main types include:
- Medicaid – A joint federal and state program providing free or low-cost health coverage to eligible low-income adults, children, pregnant women, elderly adults, and people with disabilities.
- Children’s Health Insurance Program (CHIP) – Covers children in families who earn too much to qualify for Medicaid but cannot afford private insurance.
- ACA Marketplace Plans with Premium Tax Credits – Subsidies that lower monthly premiums for individuals earning between 100% and 400% of the federal poverty level (FPL).
- Cost-Sharing Reductions (CSRs) – Additional subsidies that reduce out-of-pocket costs like deductibles and copays for those with incomes below 250% FPL.
Each program has distinct income limits and application requirements. Knowing which one fits your situation is critical.
Why Low-Income Health Insurance Plans Matter
Without coverage, a single medical emergency can lead to crippling debt. Preventive care, prescription drugs, and routine check-ups become inaccessible. Low-income health insurance plans remove these barriers, ensuring everyone has a fair shot at staying healthy.

Key Programs: Medicaid, CHIP, and ACA Subsidies
Let’s examine each program in detail so you can pinpoint where to apply.
Medicaid
Medicaid serves as the foundation of health insurance for low-income adults. Under the Affordable Care Act (ACA), states had the option to expand Medicaid to cover adults with incomes up to 138% of the FPL. As of 2025, 40 states and Washington D.C. have expanded Medicaid. In these states, eligibility is more generous.
Who qualifies?
- Adults aged 19–64 with income ≤ 138% FPL (in expansion states).
- Pregnant women (often higher income limits).
- Children, elderly, and individuals with disabilities (varying limits).
In non-expansion states, Medicaid typically only covers parents with very low incomes, pregnant women, children, and people with disabilities. Childless adults may not qualify at all.
CHIP
CHIP covers children up to age 19 in families with incomes too high for Medicaid but below a state-set threshold (often 200%–300% FPL). Coverage includes well-child visits, immunizations, dental care, and emergency services.
ACA Marketplace Plans with Premium Tax Credits
If your income is between 100% and 400% FPL, you can qualify for premium tax credits that lower your monthly payment. These credits are available through Healthcare.gov or your state marketplace. You can also get cost-sharing reductions if your income is below 250% FPL.
Basic Health Program (BHP)
A few states (Minnesota and New York) operate a Basic Health Program for residents with incomes up to 200% FPL. It provides coverage similar to a marketplace plan but with lower premiums and cost-sharing.
Income Limits and Federal Poverty Level (FPL) Guidelines
The federal poverty level is updated annually by the Department of Health and Human Services. For 2025, the FPL for a single person in the contiguous U.S. is projected to be around $15,060; for a family of four, roughly $31,200. (Exact numbers are released each January.)
Income limits for low-income health insurance plans (2025 estimates):
| Program | Income Threshold (% FPL) | Example: Single Individual | Example: Family of 4 |
|---|---|---|---|
| Medicaid (expansion states) | ≤ 138% FPL | Up to $20,783 | Up to $43,056 |
| CHIP (most states) | Up to 200% – 300% FPL | Varies (children) | Up to $93,600 (at 300%) |
| ACA Premium Tax Credits | 100% – 400% FPL | $15,060 – $60,240 | $31,200 – $124,800 |
| Cost-Sharing Reductions | ≤ 250% FPL | Up to $37,650 | Up to $78,000 |
Note: In non-expansion states, Medicaid income limits for adults are often below 50% FPL (e.g., $7,530 for a single person).
How to Determine Your FPL Percentage
- Find your household gross annual income (before taxes).
- Find the current federal poverty guideline for your family size.
- Divide your income by the guideline, then multiply by 100.
Example: If you live alone in a non-expansion state and earn $18,000, your FPL% is $18,000 ÷ $15,060 = 119.5%. That’s below 138%, so you’d qualify for Medicaid if your state expanded. If not, you may fall into a “coverage gap.”
How to Calculate Your Household Income for Eligibility
Eligibility for low-income health insurance plans uses modified adjusted gross income (MAGI). MAGI includes most sources of income but excludes certain items like Supplemental Security Income (SSI) and child support received.
What counts in MAGI?
- Wages, salaries, tips
- Self-employment income
- Unemployment compensation
- Social Security benefits (excluding SSI)
- Alimony received (for older agreements)
- Rental income, dividends, interest
What does not count?
- Child support payments received
- Veterans’ disability benefits
- Workers’ compensation
- Gifts (within limits)
Pro tip: When applying for Medicaid or marketplace subsidies, use your best estimate of expected income for the coverage year. If your income changes, update your application right away. You can adjust at renewal.
Application Tips: Documents Needed, Where to Apply, Deadlines
Applying for low-income health insurance plans doesn’t have to be daunting. Follow these steps to maximize your chances of approval.
Documents You’ll Need
Gather these before starting your application:
- Social Security numbers (or document numbers for legal immigrants)
- Employer and income information (pay stubs, tax returns, W-2 forms)
- Proof of citizenship or immigration status
- Current health insurance information (if any)
- Estimated household income for the coming year
Where to Apply
- Medicaid & CHIP: Apply through your state’s Medicaid agency or via Healthcare.gov. You can apply any time of year – there’s no limited open enrollment period for these programs.
- ACA Marketplace Plans: Apply during Open Enrollment (usually Nov 1 – Jan 15) or during a Special Enrollment Period (if you lose other coverage, move, have a baby, etc.).
- BHP (if available): Apply through your state’s program (e.g., MinnesotaCare, New York’s Essential Plan).
Tips for a Smooth Application
- Apply even if you’re unsure about eligibility. The marketplace will determine which programs you qualify for and forward your application to the correct agency.
- Use the “Check if you may qualify” tool at Healthcare.gov before filling out a full application.
- Don’t lie about income. Honest mistakes won’t lead to penalties, but intentional fraud can result in fines or disqualification.
- If your income fluctuates, provide a reasonable annual estimate. You can revisit your application mid-year if needed.
Common Application Mistakes to Avoid
- Leaving out household members (include everyone you claim as a tax dependent).
- Forgetting to report all sources of income (side gigs, freelance work).
- Missing deadlines for marketplace plans. For Medicaid/CHIP, you can apply year-round.
- Not responding to verification requests from the agency. Check your mail and online account regularly.
Special Considerations: Expansion vs Non-Expansion States
The biggest barrier to qualifying for low-income health insurance plans is living in a state that has not expanded Medicaid. As of 2025, ten states have not expanded: Alabama, Florida, Georgia, Kansas, Mississippi, South Carolina, Tennessee, Texas, Wisconsin, and Wyoming.
If you live in a non-expansion state and your income is below 100% FPL, you likely fall into the coverage gap – you earn too little for marketplace subsidies but don’t qualify for Medicaid.
What can you do if you’re in the coverage gap?
- Check if your county has a community health center that offers sliding-scale fees.
- Look into short-term limited duration plans (though these have gaps in coverage).
- Advocate for Medicaid expansion in your state.
- If you have children, apply for CHIP separately – it has different income limits.
- Consider moving to an expansion state if feasible.
If You’re Denied: Appeals and Alternative Options
Denials happen, but they aren’t the end of the road.
Common Reasons for Denial
- Income exceeds program limits.
- Missing or incorrect documentation.
- Citizenship or immigration status not verified.
- You’re incarcerated or in an institution.
How to Appeal
Every state has an appeals process. You’ll receive a notice explaining the reason for denial and instructions on filing an appeal. Act quickly – deadlines are usually 30 days.
Alternative Coverage Sources
- Employer-sponsored insurance: Even if you pay a premium, it may be affordable compared to individual plans.
- Catastrophic plans: Available to adults under 30 or those with hardship exemptions. Lower premiums but high deductibles.
- COBRA: Continue your previous employer’s plan, but it’s often expensive.
- Direct Primary Care (DPC): Monthly membership for primary care; not insurance but can reduce costs.
How to Choose the Right Plan for Your Needs
Once you qualify for a low-income health insurance plan, you may have multiple options.
Medicaid vs. Marketplace Plan
| Factor | Medicaid | Marketplace (with subsidies) |
|---|---|---|
| Cost | Free or very low copays | Premiums reduced by tax credits; may have deductibles |
| Provider Network | Usually wide but state-dependent | Varies by plan tier |
| Coverage | Comprehensive | Comprehensive (essential health benefits) |
| Enrollment | Year-round | Limited open enrollment |
Tips for comparison:
- Check if your preferred doctors and hospitals accept the plan.
- Review the drug formulary if you take prescriptions.
- For marketplace plans, choose a Silver plan if you expect high medical costs – cost-sharing reductions are only available on Silver plans.

Frequently Asked Questions
What is the income limit for low-income health insurance plans in 2025?
Income limits depend on the program and your state. For Medicaid expansion states, adults with incomes up to 138% of the federal poverty level (about $20,783 for a single person) qualify. In non-expansion states, limits are much lower. For ACA premium tax credits, you need income between 100% and 400% FPL.
Can I apply for low-income health insurance if I’m self-employed?
Yes. Self-employment income counts toward your MAGI. You’ll need to provide tax returns or profit/loss statements. Deductions for business expenses reduce your net income, which may help you qualify.
What if my income changes during the year?
If you lose income or get a raise, update your marketplace application immediately. For Medicaid, changes in income may affect eligibility. If your income drops below the threshold, you can enroll in Medicaid outside open enrollment. If it rises, your subsidies will adjust.
Are undocumented immigrants eligible for low-income health insurance plans?
Generally, no. Undocumented immigrants cannot enroll in Medicaid, CHIP, or receive marketplace subsidies. However, lawfully present immigrants (green card holders, refugees, etc.) may qualify after a five-year waiting period, though some states cover children and pregnant women sooner.
How long does it take to get approved for Medicaid?
Processing times vary by state. Many states approve applications within 45 days (or 60 if a disability determination is needed). In some states, coverage can begin immediately after a streamlined application.
Do I have to repay premium tax credits if my income ends up higher than expected?
The premium tax credit is reconciled when you file your federal taxes. If your actual income exceeds your estimate, you may have to repay part or all of the credit. There’s a cap on repayment amounts based on income. To avoid surprises, report income changes quickly.
Can I have both Medicaid and private insurance?
In most cases, if you qualify for Medicaid, you cannot also receive premium tax credits for a marketplace plan. However, if you have employer coverage and also qualify for Medicaid, you may be able to use Medicaid as secondary insurance.
What is the “coverage gap”?
The coverage gap affects adults in non-expansion states whose incomes are below 100% FPL but above their state’s Medicaid limit. They earn too little for marketplace subsidies and too much for Medicaid. These individuals have no affordable coverage option under current law.
