Mississippi residents looking for affordable health insurance in 2026 face a unique set of challenges. Because Mississippi has not expanded Medicaid under the Affordable Care Act, thousands of adults fall into a "coverage gap" where they earn too much for traditional Medicaid but too little to qualify for Marketplace subsidies. Understanding how ACA eligibility works in Mississippi is the first step toward getting covered.

How ACA Marketplace Eligibility Works in Mississippi
Mississippi uses the federal Health Insurance Marketplace at Healthcare.gov rather than running its own state exchange. That means all Marketplace enrollment, plan shopping, and subsidy applications go through the federal website.
To qualify for a Marketplace plan with financial assistance in Mississippi, you generally need to meet these requirements:
- U.S. citizen or lawfully present in the United States
- Not currently incarcerated
- Household income between 100% and 400% of the Federal Poverty Level (FPL) for the 2026 plan year
- Not eligible for Medicare, Medicaid, or qualifying employer coverage that meets affordability standards
The income requirement is the most important factor for most Mississippians. If your income falls between 100% and 400% FPL, you can receive a premium tax credit to lower your monthly insurance costs.
2026 Income Limits for ACA Subsidies in Mississippi
The federal poverty levels updated in early 2026 determine who qualifies for premium tax credits on the Marketplace. Below are the income ranges for ACA subsidy eligibility in Mississippi for the 2026 plan year.
| Household Size | 100% FPL (Minimum for Subsidies) | 400% FPL (Maximum for Subsidies) |
|---|---|---|
| 1 person | $15,960/year | $63,840/year |
| 2 people | $21,640/year | $86,560/year |
| 3 people | $27,320/year | $109,280/year |
| 4 people | $33,000/year | $132,000/year |
| 5 people | $38,680/year | $154,720/year |
| 6 people | $44,360/year | $177,440/year |
If your household income falls within these ranges, you are likely eligible for premium tax credits that reduce your monthly insurance premium. People earning between 100% and 250% FPL may also qualify for cost-sharing reductions that lower deductibles and copays on Silver-level plans.
Important change for 2026: The enhanced ACA subsidies from the American Rescue Plan and Inflation Reduction Act expired at the end of 2025. For 2026, the original ACA subsidy structure has returned. This means the "subsidy cliff" is back: households earning above 400% FPL no longer receive any premium assistance. Many Mississippians will see higher premiums compared to 2024 and 2025.
Mississippi's Medicaid Coverage Gap
This is where things get complicated for lower-income Mississippians. Mississippi is one of the states that has not expanded Medicaid under the ACA. In states that expanded Medicaid, adults earning up to 138% FPL qualify for Medicaid coverage. Mississippi chose not to expand, which creates a coverage gap.
What is the coverage gap? If you are an adult in Mississippi without dependent children, you generally do not qualify for traditional Medicaid regardless of how low your income is. At the same time, ACA Marketplace subsidies only start at 100% FPL. So if you earn less than 100% FPL ($15,960 per year for an individual in 2026), you may not qualify for either program.
Who Does Qualify for Mississippi Medicaid?
Mississippi Medicaid covers specific groups with strict income limits. Based on the income limits effective March 1, 2026 from the Mississippi Division of Medicaid:
| Category | FPL Threshold | Monthly Income (Family of 3) |
|---|---|---|
| Infants (birth to age 1) | 194% FPL | $4,531 |
| Children ages 1 to 6 | 143% FPL | $3,370 |
| Children ages 6 to 19 | 133% FPL | $3,142 |
| Pregnant women | 194% FPL | $4,531 |
| Parents/caretakers with children under 18 | Very limited | $498 |
| CHIP (uninsured children to age 19) | 209% FPL | $4,873 |
Notice how low the income limit is for parents and caretaker relatives: a family of three must earn less than $498 per month (roughly $5,976 per year) to qualify. Adults without dependent children generally have no pathway to Medicaid in Mississippi unless they have a qualifying disability.
If You Fall in the Coverage Gap
If your income is below 100% FPL and you do not qualify for Mississippi Medicaid, you still have options:
- Apply through Healthcare.gov anyway. When you provide detailed income information, you may discover you qualify for Medicaid or for subsidies based on projected annual income.
- Community health centers provide primary care on a sliding fee scale based on your ability to pay. Find locations at HRSA's Health Center Finder.
- Catastrophic health plans may be available if you are under 30 or qualify for a hardship exemption.
- Report income changes. If your expected income increases above 100% FPL during the year, you may qualify for a Special Enrollment Period to get a subsidized Marketplace plan. Contact the Marketplace Call Center at 1-800-318-2596 within 60 days of the income change.
What Financial Help Is Available on the Marketplace?
Two types of financial assistance can lower your costs on a Mississippi Marketplace plan:
Premium Tax Credits
Premium tax credits reduce your monthly insurance premium. The amount depends on your income as a percentage of FPL. For 2026, the maximum percentage of income you pay toward a benchmark Silver plan follows this schedule:
| Income Level (% of FPL) | Maximum Premium Contribution |
|---|---|
| 100% to 150% FPL | 2.0% to 4.0% of income |
| 150% to 200% FPL | 4.0% to 6.3% of income |
| 200% to 250% FPL | 6.3% to 8.2% of income |
| 250% to 300% FPL | 8.2% to 9.7% of income |
| 300% to 400% FPL | 9.7% to 9.8% of income |
| Above 400% FPL | No subsidy available |
For example, a Mississippi individual earning $20,000 per year (about 125% FPL) would pay roughly 3% of their income, or about $50 per month, toward a benchmark Silver plan. The premium tax credit covers the rest.
Cost-Sharing Reductions
If your income is between 100% and 250% FPL and you choose a Silver plan, you also get cost-sharing reductions. These lower your deductibles, copays, and out-of-pocket maximums. You must select a Silver-level plan to receive cost-sharing reductions. They are applied automatically when you enroll.
Step-by-Step: How to Enroll in an ACA Plan in Mississippi
Follow these steps to apply for Marketplace health insurance in Mississippi:
Step 1: Gather Your Information
Before you start, have the following ready:
- Social Security numbers for everyone in your household
- Immigration documents (if applicable)
- Employer and income information (pay stubs, W-2s, tax returns)
- Current health insurance policy numbers (if you have existing coverage)
Step 2: Create an Account at Healthcare.gov
Go to Healthcare.gov and create an account. You will need a valid email address and a username and password.
Step 3: Complete the Application
The application asks about your household, income, and current coverage. Answer all questions carefully. The system will determine whether you qualify for:
- Premium tax credits for a Marketplace plan
- Cost-sharing reductions
- Medicaid or CHIP
Step 4: Compare Plans
Once your eligibility is determined, you can browse available plans in your area. Plans are organized into metal tiers:
- Bronze: Lowest premiums, highest out-of-pocket costs
- Silver: Moderate premiums, eligible for cost-sharing reductions
- Gold: Higher premiums, lower out-of-pocket costs
- Platinum: Highest premiums, lowest out-of-pocket costs
Step 5: Enroll and Pay Your First Premium
Select a plan and complete your enrollment. Your coverage does not begin until you pay your first monthly premium. Set up automatic payments to avoid a coverage lapse.
Step 6: Use Your Coverage
Once your coverage starts, you can visit doctors, fill prescriptions, and receive preventive care. All ACA plans cover essential health benefits including emergency services, hospitalization, maternity care, mental health services, and prescription drugs.
Key Enrollment Dates for 2026
Mississippi follows the federal Marketplace enrollment schedule:
| Date | What Happens |
|---|---|
| November 1, 2025 | Open Enrollment begins for 2026 coverage |
| December 15, 2025 | Deadline to enroll for coverage starting January 1, 2026 |
| January 15, 2026 | Open Enrollment ends for 2026 plan year |
| February 1, 2026 | Coverage starts for enrollments made December 16 through January 15 |
Missed Open Enrollment? You can still enroll if you experience a qualifying life event such as losing other health coverage, getting married, having a baby, or moving to a new area. These events trigger a Special Enrollment Period that typically lasts 60 days. You can also apply for Medicaid or CHIP at any time throughout the year.
Other Health Coverage Options in Mississippi
Beyond ACA Marketplace plans, Mississippi residents may qualify for additional programs:
- CHIP (Children's Health Insurance Program): Covers uninsured children up to age 19 in families earning up to 209% FPL. Apply through the Mississippi Division of Medicaid or Healthcare.gov.
- Medicare: Available for adults 65 and older or those with qualifying disabilities. Contact 1-800-MEDICARE for enrollment information.

Frequently Asked Questions
Does Mississippi have expanded Medicaid?
No. Mississippi has not expanded Medicaid as of 2026. This means most adults without dependent children do not qualify for Medicaid, regardless of income. Only specific groups like children, pregnant women, and parents with very low incomes qualify for Mississippi Medicaid.
What happens if I earn less than 100% FPL in Mississippi?
You may fall into the coverage gap. Because Mississippi has not expanded Medicaid, adults earning below 100% FPL ($15,960 per year for an individual in 2026) who do not meet other Medicaid criteria may not qualify for either Medicaid or Marketplace subsidies. You should still submit an application through Healthcare.gov, as your projected income or household circumstances may open up options.
Can I get a Marketplace plan without a subsidy?
Yes. Anyone can purchase an unsubsidized Marketplace plan through Healthcare.gov during Open Enrollment or a Special Enrollment Period. You will pay the full premium, but the plan still must cover all essential health benefits required by the ACA.
What income counts toward ACA eligibility?
ACA eligibility uses Modified Adjusted Gross Income (MAGI). This includes wages, salary, self-employment income, Social Security benefits, unemployment compensation, and certain other types of income. For most people, MAGI is similar to adjusted gross income on your tax return.
How do I report an income change during the year?
Log in to your Healthcare.gov account and update your application with the new income information. If the change makes you eligible for more or less financial assistance, your subsidy amount will be adjusted. Reporting changes promptly helps you avoid owing money at tax time or missing out on credits you deserve.
Where can I get free help enrolling?
Mississippi has certified navigators and trained assisters who provide free help with Marketplace applications. You can find local assistance at Healthcare.gov's Find Local Help tool or by calling the Marketplace Call Center at 1-800-318-2596 (TTY: 1-855-889-4325).
