Mississippi residents have access to quality health insurance through the Affordable Care Act (ACA) marketplace, with most enrollees qualifying for significant financial assistance. In fact, approximately 99% of Mississippi marketplace enrollees received premium subsidies during the most recent open enrollment period, saving an average of $576 per month on their health insurance premiums. Whether you are shopping for coverage for the first time or looking to switch plans, this guide covers everything you need to know about Mississippi ACA benefits and coverage for 2026.
How the ACA Marketplace Works in Mississippi
Mississippi uses the federal marketplace at Healthcare.gov for ACA enrollment. The state does not operate its own exchange, so all plan shopping, applications, and enrollment happen through the federal platform.
Through the marketplace, you can compare health insurance plans from multiple insurers side by side. For 2026 coverage, five insurance companies offer plans in Mississippi, giving residents options across different price points and coverage levels.
All ACA marketplace plans must cover ten essential health benefits:
- Ambulatory (outpatient) care
- Emergency services
- Hospitalization
- Maternity and newborn care
- Mental health and substance use disorder services
- Prescription drugs
- Rehabilitative services and devices
- Laboratory services
- Preventive and wellness services (including chronic disease management)
- Pediatric services, including dental and vision
Plan Metal Tiers
ACA plans are organized into four tiers based on how costs are shared between you and the insurance company:
| Tier | You Pay (Approx.) | Insurer Pays (Approx.) | Best For |
|---|---|---|---|
| Bronze | 40% | 60% | Low premiums, healthy individuals |
| Silver | 30% | 70% | Moderate use, subsidy-eligible households |
| Gold | 20% | 80% | Regular medical needs |
| Platinum | 10% | 90% | Frequent medical care |
Silver plans are especially valuable for lower-income households because they qualify for cost-sharing reductions (CSRs) that lower deductibles and copays in addition to premium subsidies.
Income Limits for ACA Subsidies in Mississippi
ACA premium tax credits (subsidies) help reduce your monthly insurance premium. For 2026 coverage, eligibility is based on the 2025 Federal Poverty Level (FPL) guidelines. In Mississippi, a non-expansion state, subsidies are available to individuals and families with income between 100% and 400% of FPL.
Important for Mississippi: Because Mississippi has not expanded Medicaid, the subsidy eligibility floor starts at 100% FPL. If your income falls below 100% FPL, you may fall into what is known as the "coverage gap," meaning you earn too much for traditional Medicaid but too little to qualify for marketplace subsidies.
2026 ACA Subsidy Income Limits (Based on 2025 FPL)
| Household Size | 100% FPL (Minimum) | 150% FPL | 250% FPL | 400% FPL (Maximum) |
|---|---|---|---|---|
| 1 | $15,650 | $23,475 | $39,125 | $62,600 |
| 2 | $21,150 | $31,725 | $52,875 | $84,600 |
| 3 | $26,650 | $39,975 | $66,625 | $106,600 |
| 4 | $32,150 | $48,225 | $80,375 | $128,600 |
| 5 | $37,650 | $56,475 | $94,125 | $150,600 |
| 6 | $43,150 | $64,725 | $107,875 | $172,600 |
Note: For 2026, the "subsidy cliff" has returned. This means that if your income exceeds 400% FPL, you will not qualify for any premium tax credits. This is a change from 2021 through 2025, when enhanced subsidies were available at all income levels above 400% FPL.
Cost-Sharing Reductions
If your household income is between 100% and 250% FPL and you choose a Silver plan, you also qualify for cost-sharing reductions. These lower your deductibles, copays, and out-of-pocket maximums:
- 100% to 150% FPL: Highest level of CSR benefits (plan acts like a Platinum plan)
- 150% to 200% FPL: Strong CSR benefits (plan acts like a Gold plan)
- 200% to 250% FPL: Moderate CSR benefits
The Mississippi Coverage Gap
Mississippi is one of the states that has not expanded Medicaid under the ACA. This creates a coverage gap that affects an estimated 71,000 to 200,000 adults in the state.
Who falls in the coverage gap?
- Adults aged 19 to 64 without dependent children who earn less than 100% FPL ($15,650 for an individual)
- Parents earning above Mississippi's extremely low traditional Medicaid limit (roughly 24% FPL, or about $292 per month for an individual) but below 100% FPL
These individuals earn too much for Mississippi Medicaid but not enough to qualify for ACA marketplace subsidies. If you are in this situation, you may want to explore options such as community health centers, hospital charity care programs, or free clinics in your area.
Legislative efforts to expand Medicaid in Mississippi have been introduced in recent years, but as of early 2026, expansion bills have not passed.
Mississippi Medicaid and CHIP: Who Qualifies?
Understanding Mississippi Medicaid eligibility is important because it determines whether you should apply through Medicaid or the ACA marketplace.
Mississippi Medicaid Income Limits
| Category | Income Limit (% FPL) | Monthly Income (Family of 3) |
|---|---|---|
| Parents with dependent children | ~24% FPL | ~$495 |
| Pregnant women | 194% FPL | $4,420 |
| Infants (birth to age 1) | 194% FPL | $4,420 |
| Children ages 1 to 5 | 143% FPL | $3,287 |
| Children ages 6 to 18 | 133% FPL | $3,065 |
| Childless adults | Not eligible | N/A |
Postpartum coverage: Mississippi extended postpartum Medicaid coverage to 12 months after birth, up from 60 days previously.
CHIP (Children's Health Insurance Program)
Mississippi CHIP covers uninsured children up to age 19 in families with income up to 209% FPL. For a family of three, that is approximately $4,753 per month or $57,039 per year.

Frequently Asked Questions
What is the cheapest ACA plan available in Mississippi?
Bronze plans typically have the lowest monthly premiums. With subsidies, many Mississippi residents can find plans for $0 or very low monthly premiums. The exact cost depends on your income, age, location, and household size.
Can I get ACA coverage if I have a pre-existing condition?
Yes. Under the ACA, insurance companies cannot deny coverage or charge higher premiums based on pre-existing conditions. This applies to all marketplace plans in Mississippi.
What happens if my income changes during the year?
You should report income changes to the marketplace as soon as possible. If your income increases, your subsidy may decrease. If your income drops, you may qualify for a larger subsidy or even Medicaid. Failing to report changes could result in owing money at tax time.
Is dental coverage included in ACA plans?
Pediatric dental coverage is included in all ACA plans. Adult dental coverage is not required but may be available as an add-on or included in some plans. Check individual plan details when comparing options.
What if I cannot afford any marketplace plan?
If your income falls below 100% FPL and you are not eligible for Medicaid, you may be in the coverage gap. In that case, look into community health centers, hospital financial assistance programs, and free clinics. You can also check if you qualify for other assistance programs using our benefits screener.
