Small Business Health Insurance in South Carolina: What You Need to Know
South Carolina's small group market is dominated by BlueCross BlueShield of South Carolina, which has built deep provider relationships across the state over decades. The market is competitive in the Charleston, Columbia, and Greenville metro areas, with national carriers providing meaningful alternatives. Rural South Carolina has fewer options.
South Carolina has not expanded Medicaid. This is a critical consideration for employers: lower-wage workers in South Carolina do not have Medicaid as a safety net, which means your group plan may be the only affordable coverage option available to them. This makes offering group coverage more strategically important in SC than in states that have expanded Medicaid.
Who Qualifies as a Small Employer in South Carolina
South Carolina follows the ACA definition: 1–50 full-time equivalent employees. Full-time is 30 or more hours per week. Because South Carolina has not expanded Medicaid, employees earning below the individual market subsidy threshold (~100% FPL) can be in a coverage gap. Offering a group plan is one of the few ways to provide those employees access to affordable coverage. Businesses with fewer than 50 FTEs are not required by law to offer coverage.
Coverage Options for South Carolina Small Businesses
ACA Small Group Plans
All South Carolina small group plans are guaranteed issue, community-rated, and must include ACA essential health benefits. The South Carolina Department of Insurance regulates carrier conduct and plan designs.
Federal SHOP Marketplace
South Carolina employers access the SHOP at healthcare.gov/small-businesses. Using SHOP is required to claim the Small Business Health Care Tax Credit.
QSEHRA Alternative
South Carolina employers with fewer than 50 employees can use a QSEHRA. 2026 limits: $6,450 (self-only) and $13,100 (family). In Columbia, Charleston, and Greenville the individual market has solid options. Rural South Carolina has fewer individual market choices, which is an important consideration before choosing QSEHRA over a group plan.
Carriers Offering Small Group Plans in South Carolina
- BlueCross BlueShield of South Carolina — The dominant statewide carrier. Broad network covering Prisma Health, MUSC Health, Tidelands Health, AnMed Health, and most SC hospital systems. The standard choice for South Carolina employers who want comprehensive statewide coverage, particularly those with employees in rural or smaller markets.
- UnitedHealthcare — Competes in Charleston, Columbia, and Greenville. National network access is an advantage for businesses with employees who travel or need care out of state.

- Aetna (CVS Health) — Participates in select South Carolina small group markets. CVS pharmacy integration.
South Carolina's Non-Expansion Status and Your Group Plan
South Carolina is one of the states that has not expanded Medicaid under the ACA. This means workers earning below 100% FPL do not qualify for ACA marketplace subsidies and may not qualify for Medicaid. For employees in that income range, your group plan may be the only realistic path to coverage. Employers in manufacturing, food service, agriculture, and hospitality — industries with wages that often fall near or below the poverty threshold — should take note: group coverage plays a larger safety net role in South Carolina than in expansion states.
The Small Business Health Care Tax Credit in South Carolina
South Carolina employers purchasing through federal SHOP may qualify for up to 50% of premiums paid:
- Fewer than 25 FTEs
- Average wages below approximately $56,000 per year
- Pay at least 50% of each enrolled employee's self-only premium
- Purchase through the federal SHOP marketplace
South Carolina's manufacturing, retail, food service, and tourism industries frequently qualify. The credit is particularly valuable for Upstate SC manufacturers and Lowcountry hospitality businesses.

The ICHRA Option in South Carolina
There is a third route that neither a group plan nor a QSEHRA covers. An ICHRA lets you set a monthly amount and reimburse staff tax-free for individual coverage they choose themselves — no contribution cap, no employer size limit, and the policy belongs to the employee rather than to you. One number decides whether it works, and it is not the one most people expect.
| Employee’s W-2 wages | Most they can be asked to pay | So your contribution must be at least |
|---|---|---|
| $28,000 | $232 / month | $319 / month |
| $42,000 | $349 / month | $203 / month |
| $58,000 | $481 / month | $70 / month |
Worked against South Carolina’s median lowest-cost Silver for a 40-year-old ($552 a month) and the 10.22% affordability threshold for 2027. The real test runs per employee, against the lowest-cost Silver in their own rating area at their own age — the shape of the answer is right, the exact figures move.
Premiums are high enough in South Carolina that even a $58,000 earner needs $70 a month before the offer counts as affordable. That is the useful part: below those numbers an employee can decline the ICHRA and claim a marketplace subsidy instead, and for your lower-paid staff that subsidy is often worth more than the contribution you were planning. Setting the number deliberately is the difference between a benefit people use and one they opt out of.
South Carolina’s final 2027 rates rise about 22.1% on average, so set the contribution against next year's premium rather than this year's. And with no Medicaid expansion in South Carolina, an employee who turns the offer down has the marketplace or nothing. How an ICHRA works in full, including the eleven employee classes and the 90-day notice.

Why does South Carolina's non-expansion status matter for my group plan?
