Small Business Health Insurance in South Carolina
South Carolina employers with up to 50 employees can offer health benefits three ways: a fully insured small-group plan, an individual coverage HRA that reimburses each employee's own plan, or a QSEHRA for businesses under 50 full-time employees. Which one fits depends on your budget, how many people you cover and how the South Carolina small-group market is priced for 2027.
Private health insurance in South Carolina
Most people I help in South Carolina end up on a private plan, not a Marketplace plan. Private, medically underwritten health insurance is priced on your age, zip code and health instead of your income, so a strong year never raises your premium and there is no tax credit to pay back in April.
Why people leave the Marketplace
- Premiums keep climbing. South Carolina Marketplace premiums are rising 22.1% on average for 2027.
- The subsidy cliff. Above 400 percent of the poverty level ($63,840 for one person, $132,000 for a family of four) you pay full price.
- Surprise tax bills. Underestimate your income and you repay the tax credit in April.
- Narrow networks. Many plans are local HMOs or EPOs that need referrals and cover little outside the area.
- High out-of-pocket costs. 2027 out-of-pocket maximums reach $12,000 per person and $24,000 per family.
- One window a year. Outside open enrollment you need a qualifying life event to enroll or switch.
What a private plan does differently
- Start any month. If approved, coverage can begin the first of next month, with no wait for open enrollment.
- Networks that travel. Many private plans use national PPO networks, which can give you in-network doctors outside South Carolina too. Networks vary by plan.
- Can cost less than full-price Marketplace plans for some healthy applicants above the subsidy line.
- Accident coverage the Marketplace does not offer. A private plan can be paired with accident coverage, a separate policy. What it includes varies by plan.
- Approval is based on health. You answer health questions, and acceptance is not guaranteed.
With a significant health condition, or income low enough for a large tax credit, a Marketplace plan can be the better fit, and I will tell you if it is. Either way you see both side by side.
Private plans are not ACA Marketplace plans. Benefits, exclusions and pre-existing condition rules differ by plan and by state, so review the plan details before you enroll.

The South Carolina small-group market for 2027
South Carolina law defines a small employer as one with no more than 50 employees that has at least one employee on the first day of the plan year. Final 2027 small-group filings, approved almost exactly as submitted, average about 8.9 percent, a fraction of the 22 percent individual increase. That gap is the main story for South Carolina owners this year. When counting employees, affiliated companies, and companies that can file a combined state tax return, are treated as one employer, so splitting a business does not create two small groups.
South Carolina options and rules for small employers
With South Carolina now starting from federal adjusted gross income, an ICHRA or QSEHRA that is tax-free federally stays tax-free on the state return. South Carolina offers no state small-business health tax credit, so only the federal credit applies. Self-funded multiple employer plans must be state-licensed and cover at least 250 employees, which keeps most very small firms in fully insured coverage. On continuation, South Carolina's six-month law reaches insured plans at firms below the federal COBRA threshold, and the employer must tell each departing worker about the right and the premium.
South Carolina at a glance for owners and employees
South Carolina buyers enroll through HealthCare.gov. The state's continuation law covers insured group plans and lasts the rest of the month coverage ends plus six months, after six months of coverage, at the full group premium. South Carolina's insurance department adopted the federal short-term limits in 2024, three months initial and four months total, replacing its older 11- and 33-month limits. Final 2027 individual rates average about 22 percent higher, among the largest increases on this list, while small-group plans rise a comparatively modest 8.9 percent.

Group plan or HRA
A small-group plan gives everyone the same coverage and usually requires a minimum share of employees to enroll and a minimum employer contribution. An ICHRA lets you set a monthly allowance by employee class and lets each person pick their own individual plan; it works for any size business. A QSEHRA is simpler and capped by annual limits, for employers under 50 full-time employees. Employees offered an affordable ICHRA lose access to the Marketplace tax credit, so set the allowance with that in mind.
Covering the owner
An owner-only business cannot buy a small-group plan in most states; it needs at least one eligible employee who is not an owner or an owner's spouse. Until then the owner buys individual coverage. Once you have employees, you can usually join the group plan or the ICHRA as well.
Tax treatment
Employer contributions to group premiums and HRA reimbursements are generally deductible to the business and tax-free to employees. General information, not tax advice — confirm with your CPA based on your specific entity structure.
For 2027 the Marketplace credit stops at 400 percent of the poverty level: $63,840 for one person, $86,560 for two and $132,000 for a family of four. The out-of-pocket maximum for 2027 Marketplace plans is $12,000 for one person and $24,000 for a family. The full guide covers the rest.
