Obamacare South Carolina 2026: Plans, Costs & Enrollment Guide

South Carolina has a sizable and steadily growing Marketplace. According to the Centers for Medicare & Medicaid Services (CMS), roughly 575,000 South Carolinians enrolled in Obamacare plans for the 2024 coverage year — a number that has climbed sharply as subsidies made coverage genuinely affordable for working households.

If you live in South Carolina — Greenville, Columbia, Charleston, Hilton Head, Myrtle Beach, or anywhere in between — this guide explains what plans are available, what they actually cost in your county, how the subsidy math works, and what to do if you fall into the coverage gap or are in a Spanish-speaking household navigating the system.

How Obamacare works in South Carolina

South Carolina uses the federal Marketplace — HealthCare.gov — to shop and enroll in Affordable Care Act (ACA) plans. The state has never built a state-based exchange, which means South Carolinians follow the federal calendar, the federal subsidy formulas, and the federal eligibility rules.

The basic flow is:

1. You enter your zip code, household size, and estimated 2026 income at HealthCare.gov (or call a licensed agent).
2. The site checks Medicaid first. If you do not qualify for South Carolina Medicaid, it shows you Marketplace plans with the subsidy already applied.
3. You compare plans by premium, deductible, network, and the carriers available in your county.
4. You pick one and enroll. Coverage starts the first of the next month, depending on when you enroll.

South Carolina did not expand Medicaid under the ACA. This is the most important thing to know if your household income is very low — and it is covered in detail below.

The South Carolina Medicaid situation

South Carolina is a non-expansion state, which means Medicaid eligibility for adults is narrow:

• Adults without dependent children generally cannot get South Carolina Medicaid no matter how low their income is (unless they have a qualifying disability).
• Parents of dependent children can get South Carolina Medicaid only at very low income — well below the federal poverty level.
• Children can get South Carolina Healthy Connections Medicaid or CHIP at much higher income limits — far more generous than adult eligibility.
• Pregnant women qualify at higher income for pregnancy-related care.

This creates a coverage gap. If you earn below 100% of the federal poverty level — roughly $15,000 for a single person — you may earn too much for South Carolina Medicaid but too little for a Marketplace premium tax credit, which requires income above that 100% line.

Here is the honest part: the gap is real, but it is not always a dead end. The workarounds a licensed agent will check:

• Counting all reasonably expected income — gig work, side jobs, sporadic wages, freelance income. Many people underestimate their year. Accurately projecting your annual income often lifts you above the 100% FPL line and unlocks full subsidies.
• Including spousal income if you file taxes jointly.
• Using projected annual income, not month-to-month — the Marketplace looks at your whole year.
• Eligibility for children’s coverage through Healthy Connections or CHIP even when the adults are in the gap.
• Sliding-scale care at community health centers while you work out a longer-term option.

If your income lands just above 100% FPL, the subsidies are at their most generous — at that income level a household contributes only about 2.10% of income toward a benchmark plan, so many people in that range still pay $0 or near-$0 per month for a Silver plan, even after the Inflation Reduction Act’s enhanced subsidies expired at the end of 2025.

Hispanic enrollment in South Carolina

South Carolina has a growing Hispanic population, concentrated in and around the state’s largest metro areas. According to the US Census Bureau, the Hispanic or Latino share of the population has grown steadily over the past two decades. The community is concentrated in:

• Greenville and the Upstate — the largest Hispanic population in the state
• Columbia and the Midlands — established and growing
• Charleston and the Lowcountry — coastal and service-economy communities
• Hilton Head and Beaufort County — significant resort-and-hospitality workforce
• Myrtle Beach and the Grand Strand — seasonal and year-round communities

Marketplace enrollment assistance in Spanish is available through licensed agents, navigators, and Federally Qualified Health Centers across these areas.

Top carriers in South Carolina (2026)

Carriers commonly available in South Carolina’s Marketplace for 2026 include:

• Blue Cross Blue Shield of South Carolina — broad statewide network
• Ambetter from Absolute Total Care — competitive premiums, strong in metro areas
• Molina Healthcare — focused on lower-cost Silver plans
• UnitedHealthcare — selective county coverage

The carrier mix varies by county. The Greenville and Columbia metro areas typically have the widest selection, while rural counties may have only one or two carriers. A licensed agent can pull the exact list for your zip code in seconds.

How much does Obamacare cost in South Carolina?

Real numbers from the KFF Marketplace Enrollment Survey:

• The large majority of South Carolina Marketplace enrollees receive a premium tax credit (KFF). Lower-income households often pay $0 or near-$0 after subsidies.

Three things drive your specific cost:

1. Age. A 25-year-old pays less than a 55-year-old at the same income.
2. County. Premiums vary by county. The Upstate and Midlands often run lower than some rural areas.
3. Household income. Lower income, bigger subsidy. Subsidies phase down as income rises.

Run the calculator for your number

The actual subsidy depends on your age, household size, household income, and ZIP-county. The calculator at the top of the page runs the 2026 IRS formula (Rev. Proc. 2025-25, post-IRA expiration) and produces an estimate in seconds. In a non-expansion state like South Carolina, projecting your annual income accurately can be the difference between the coverage gap and full Marketplace subsidies — a licensed South Carolina agent verifies the exact number for your real plan and county in about 15 minutes, free, Spanish available where noted.

Federally Qualified Health Centers (FQHCs) in South Carolina

Even if you fall into the coverage gap or are between options, FQHCs charge on a sliding scale based on income. South Carolina has community health centers serving:

• Greenville and the Upstate — multiple locations, bilingual staff
• Columbia and the Midlands — established community health networks
• Charleston and the Lowcountry — coastal community centers
• Rural South Carolina — migrant and rural health programs

Search the HRSA Find a Health Center tool for FQHCs near your zip code.

Immigrant eligibility in South Carolina

South Carolina’s immigrant population has grown alongside its metro areas. The Marketplace rules are the same federal rules everywhere:

• Lawfully present immigrants can buy Marketplace plans and qualify for subsidies from day one — no five-year waiting period.
• Undocumented immigrants cannot buy on the federal Marketplace.
• Mixed-status families apply together — only eligible members are enrolled.
• HealthCare.gov does not share immigration information with ICE. This is protected by federal law.

If you do not have a Social Security Number, you can still apply using immigration document numbers. Read our guide on applying without an SSN.

Common South Carolina-specific questions

“I work seasonally — can I get Obamacare?” Yes. The Marketplace uses estimated annual income. Seasonal workers, hospitality and resort workers, gig workers, freelancers, and self-employed people all qualify. You estimate your year and adjust if it changes. Accurately projecting your income is especially important in a non-expansion state — it can be the difference between the coverage gap and full subsidies.

“My employer offers insurance but it is expensive.” If your employer’s plan would cost more than 9.96% of your household income for self-only coverage in 2026, you may qualify for a Marketplace subsidy instead. An agent can run the math.

“I earn very little — what are my options?” If you earn below 100% of the federal poverty level, you may be in the coverage gap. A licensed agent can check whether projecting all your income sources lifts you above the threshold, and can point you to community health centers and children’s coverage in the meantime.

“I have a pre-existing condition.” This cannot be used against you. Marketplace plans cannot deny coverage or charge more for any health condition. Federal law since 2014.
