South Carolina Health Insurance for the Self-Employed: 2027 Playbook

South Carolina’s ACA Marketplace runs through Healthcare.gov. For self-employed South Carolinians, the 2027 plan year brings a competitive carrier lineup, consistent subsidy eligibility for most middle-income households, and the usual self-employed income-projection questions.

Here’s what SC self-employed shoppers need to know.

The South Carolina coverage context

South Carolina did not expand Medicaid. For adults without dependent children, Healthy Connections (SC Medicaid) covers only categorically eligible populations — pregnant women up to 194% FPL, parents with children up to 67% FPL, disabled adults, and seniors meeting income and asset tests.

The result: a coverage gap for non-disabled adults earning under 100% FPL — too much for SC Medicaid, too little for ACA subsidies. If you’re a self-employed South Carolinian projecting income at or above 100% FPL, Marketplace subsidies kick in. Below that, your options narrow.

The 2027 South Carolina carrier lineup

• BlueCross BlueShield of South Carolina — statewide network, deepest provider inclusion, higher premiums
• Molina Healthcare — competitive premiums, safety-net-focused model
• Ambetter (Celtic/Centene) — multi-tier plans statewide
• Absolute Total Care — Centene-affiliated, targeted South Carolina plans
• SelectHealth — expanding presence

Income projection for self-employed shoppers

ACA subsidies depend on projected Modified Adjusted Gross Income (MAGI) for 2027. The 2027 subsidy schedule reverts to the original ACA structure (enhanced ARP/IRA rates lapsed after 2025):

• 100-150% FPL: ~2.07% expected contribution
• 150-200% FPL: 3-6.5%
• 200-400% FPL: 6.5-9.83%
• Over 400% FPL: no subsidy (cliff)

For a single South Carolina self-employed shopper, 400% FPL = ~$62,600. For a family of four, 400% FPL = ~$128,600. Estimate your subsidy with your 2027 projected income.

Levers for managing MAGI

• SEP-IRA contributions — up to 25% of net SE earnings. Immediate MAGI reduction.
• Solo 401(k) contributions — up to $23,500 (2027 projection) plus 25% of net SE income. Significant MAGI lever.
• HSA contributions — if on an HSA-eligible HDHP
• Self-employed health insurance deduction — premium is deductible above-the-line
• Qualified business income deduction (Section 199A) — up to 20% of qualified business income for eligible businesses

Regional network considerations

Columbia metro

Prisma Health is the dominant provider network in the Midlands. BCBSSC has the strongest Prisma Health integration; Molina and Ambetter also include Prisma.

Charleston metro

Medical University of South Carolina (MUSC) and Roper St. Francis are the dominant systems. Verify your specific specialists in the plan’s directory before enrolling.

Greenville / Spartanburg (Upstate)

Prisma Health and Bon Secours St. Francis are the dominant Upstate systems. BCBSSC, Ambetter, and Molina all have strong Upstate presence.

Rural counties

Network depth varies. BCBSSC typically has the broadest rural Carolinas footprint.

Common self-employed SC mistakes

• Projecting income too low and falling into the coverage gap at tax reconciliation
• Choosing by premium alone without verifying providers and formulary
• Missing the SE health insurance deduction and over-paying on MAGI-driven taxes
• Not using retirement contributions as MAGI levers when near a subsidy bracket boundary
