Small Business Health Insurance in South Carolina: What Does It Cost, What Is Required, and Which Plan Fits My Team?
Written and reviewed by Dick Tracy, licensed health insurance broker (NPN 20414610) · Published October 3, 2026
Quick answer A South Carolina business with fewer than 50 full-time equivalent employees is not required to offer health insurance, and there is no penalty for skipping it. At 50 or more, the federal employer mandate applies. South Carolina's small group market covers employers with 2 to 50 employees and asks no health questions. Average employer coverage in South Carolina costs $8,552 a year for single coverage and $25,046 for a family (MEPS-IC, 2025, all firm sizes). For 2027, the five companies that filed small group rates proposed average increases from 5.96% to 11.50%, and those filings were still pending review on October 3, 2026. A group plan is not the only way to take care of your people. I educate, you decide.
I'm Dick Tracy, a health insurance broker. I'm licensed in South Carolina (NPN 20414610), one of 25 states I hold a license in, and I work with 80+ carriers. I am not local and I won't pretend to be: my office is in Buffalo, New York, and I work with South Carolina business owners by phone or Zoom. I came from the healthcare side of this business, so there is no gag clause on me. This page is for the owner with employees. If it is just you, or you and your spouse, start with my self-employed in South Carolina page instead. The biggest trap for an owner with a team: signing the first group quote because you think it is the only option. Sometimes the math doesn't math.

Small business health insurance requirements in South Carolina: do I have to offer it?
With fewer than 50 full-time equivalent employees (FTEs), no. The duty to offer coverage is a federal one, and it starts at "an average of at least 50 full-time employees (including full-time-equivalent employees)" in the prior year (IRS). Below that line there is no penalty for not offering a plan. Part-time hours count toward that number, so do the count before you assume you are under it.
| Your size | Required to offer? | What applies to you |
|---|---|---|
| Owner only, or owner and spouse | No | Small group is generally closed to you. See the box below. |
| Owner with one employee | It depends | The statute says at least one employee. The Department describes the market as 2 to 50. Call me and I check it with the company. |
| 2 to 49 FTEs | No, and no penalty | Small group coverage is available if you want it. So are two other routes. |
| An average of 50 or more full-time and FTE employees | Yes, federal mandate | The 2027 penalties and the affordability test below. |
Sources: South Carolina Department of Insurance ("The small group market for health insurance coverage includes small employers with 2-50 employees"); South Carolina Code 38-71-1330 (small employer: no more than fifty eligible employees, and at least one employee on the first day of the plan year); IRS, employer shared responsibility provisions.
At 50 or more, the 2027 IRS numbers: if you do not offer coverage and even one full-time employee gets a marketplace tax credit, the penalty is $3,780 per full-time employee for the year, not counting the first 30. If the coverage you offer is unaffordable or falls short, it is $5,670 for each full-time employee who gets that credit (IRS Rev. Proc. 2026-22). For 2026 those were $3,340 and $5,010 (IRS Rev. Proc. 2025-26). "Affordable" has a number too: for 2027 plan years it is 10.22% (IRS Rev. Proc. 2026-26), and for 2026 plan years, the employee's required contribution cannot be more than 9.96% of household income (IRS Rev. Proc. 2025-25). If you are near the line, my employer affordability calculator does the math.
Who counts for a South Carolina small group plan: the statute defines an eligible employee as someone "who works on a full-time basis and has a normal workweek of thirty or more hours" (South Carolina Code 38-71-1330).
Business owner with no employees: small group is generally closed to you
The South Carolina Department of Insurance says it in one sentence: "Individuals that are self-employed or have no employees are generally not able to purchase coverage in the small group market, but may access coverage in the individual market" (South Carolina Department of Insurance). The Department describes the small group market as employers with 2 to 50 employees.
What else can that owner do? First, a pre-established ERISA group plan: a solo owner is merged into a group plan that already exists, with group rates, a true nationwide PPO network of the PHCS and MultiPlan type, and a policy you own. No employees required. Here is the ERISA cheat code, explained. Second, a customized individual plan. The doors for a solo owner are on my self-employed in South Carolina page.
How much does small business health insurance cost in South Carolina?
Here is the honest anchor: average annual premiums for private-sector employer coverage in South Carolina, from the federal employer survey. They cover employers of all sizes, so this is a benchmark, not a quote.
| Coverage tier (2025) | South Carolina total | Employee pays | Employer pays | US total |
|---|---|---|---|---|
| Single | $8,552 | $1,814 | $6,738 | $9,025 |
| Employee-plus-one | $16,317 | $4,879 | $11,438 | $17,901 |
| Family | $25,046 | $8,269 | $16,777 | $26,281 |
Source: Agency for Healthcare Research and Quality, Medical Expenditure Panel Survey Insurance Component (MEPS-IC), via KFF State Health Facts, data year 2025: single, employee-plus-one, family. All firm sizes, per enrolled employee.
In monthly terms, single coverage runs about $713, with the employee paying about $151 of it. Family coverage runs about $2,087 a month, with the employee paying about $689. South Carolina runs about 5% below the national average on both single and family coverage. Watch the family number anyway. South Carolina employees pay $8,269 a year toward family coverage, against $7,314 nationally. The employer still carries $6,738 a year per person on single coverage alone.
What does the employer have to contribute? The contribution and participation numbers come from the insurance company. The Department of Insurance's 2026 page says all small group plans in South Carolina "are sold strictly through the private market" (South Carolina Department of Insurance), so there is no exchange rule to quote you here. Get the company's rule in writing before you quote. My advice on a group plan: pick a flat dollar amount per person, not a percentage of premium, as long as it clears the company's contribution minimum. If you want the tax credit, the IRS generally requires a uniform percentage of at least 50%. Every employee is rated on their own age, so a percentage means your cost jumps with every older hire and every renewal. A flat amount is a number you can budget.
South Carolina small group rates for 2027: what the companies proposed
South Carolina companies file small group rates with the Department of Insurance every year, and the Department reviews them. As of October 3, 2026, the Department has not posted its 2027 summary, and the federal rate review site shows all five South Carolina small group filings for 2027 as "Pending Review." So the 2027 numbers below are proposed, not approved: average increases from 5.96% to 11.50%, depending on the company. Last year's filings were marked final on October 14, 2025, so I expect the 2027 decisions this month (expected, not announced). For 2026, the Department approved a small group average of 10.93%, weighted by written premium, with plan-level changes from 2.22% to 14.00%.
| Company filing small group in South Carolina | 2026 approved average | 2027 proposed average | 2027 proposed range across the filing |
|---|---|---|---|
| BlueChoice HealthPlan of South Carolina | 9.90% | 8.75% | 0.51% to 16.69% |
| Blue Cross and Blue Shield of South Carolina | 11.80% | 8.77% | 4.75% to 11.87% |
| UnitedHealthcare Insurance Company | 8.08% | 5.96% | 2.57% to 11.69% |
| UnitedHealthcare Insurance Company of the River Valley | 8.68% | 7.76% | 5.98% to 10.17% |
| UnitedHealthcare of South Carolina | 8.67% | 11.50% | 9.53% to 12.98% |
Sources: 2026 approved averages are the "Average Increase" column of the South Carolina Department of Insurance, 2026 Health Insurance Plans, Rate Changes for Small Group Market Coverage. 2027 proposed figures are from the federal rate review site (ratereview.healthcare.gov), South Carolina, small group, 2027, checked October 3, 2026: each filing's preliminary average rate and its range of rate change, with a final determination of "Pending Review." The list is alphabetical and is not a recommendation.
Read the table like a detective. Four of the five companies are asking for a smaller average increase than the state approved for them for 2026. One is asking for more. Now a piece of my own math: a plan that took 11.80% for 2026 and takes 8.77% for 2027, if that request is approved as filed, is up about 22% in two years. On that track a $713 monthly premium becomes about $867. That is my arithmetic and an illustration, not a quote and not a state figure.
How a small group plan is priced: no health questions. Under the federal rating rule (45 CFR 147.102) the premium can vary only by age, rating area, family size, and tobacco use, never by health or claims history. The oldest adult rate can be no more than three times the youngest. A young, healthy team gets credit for being young and zero credit for being healthy, which is why a small group quote is often too expensive for them.
South Carolina small business health insurance plans: the three routes I use
There is no single best plan, only a best route for your team. What kind of tank should we build?
| 1. Traditional fully insured small group | 2. Pre-established ERISA group plan | 3. No group plan at all | |
|---|---|---|---|
| What it is | A South Carolina small group policy from an insurance company | Your people merge into a group plan that already exists under ERISA | You may not need a group plan at all: I customize the plan based on the situation |
| Who can use it | A business with 2 to 50 employees. Owner-only businesses generally cannot. | A solo owner or a small business's people. No employees required. | The owner and family, or each person buying their own policy |
| Health questions | None. Guaranteed issue. | Best fit for healthy people | Depends on the plan. Marketplace plans ask none. |
| Network | Depends on the company and plan | True nationwide PPO (PHCS and MultiPlan type) | Chosen person by person, around their own doctors |
| Employer rules | Company participation and contribution minimums. Federal COBRA at 20 or more employees, South Carolina's six-month continuation rule under that. | One simple compliance step I walk you through. | No group plan to administer. Each person owns their own policy. Call me and I walk you through it. |
| Policy owner | The employer holds the group contract | The person | The person |
| Usually fits | Older teams, teams with health conditions, owners who want one plan for everyone | Healthy owners and healthy small teams | Very small businesses, owner-and-spouse businesses, teams where half want coverage and half do not |
Small group column: South Carolina Department of Insurance, South Carolina Code 38-71-1330 and 38-71-770, 45 CFR 147.104 (guaranteed availability). Routes 2 and 3 describe my own practice; route 2 is explained on the ERISA cheat code page.
On route 3: a group plan is one design stretched over a 26-year-old who never sees a doctor and a 58-year-old with a specialist. Customized individual coverage for each person is often more cost-effective than a one-size-fits-all group plan, especially for a young, healthy crew of 2 to 15. A couple of years ago I saved a business over $30,000 in a year by putting the routes side by side.
Charleston, Columbia, Greenville, Myrtle Beach: 46 rating areas, one per county
South Carolina has 46 rating areas, and each one is a single county. Under the federal rule, a small group is priced by the rating area of the business's principal address, not where each employee lives. So your county is part of your price.
| County | Largest city people search for | Rating area |
|---|---|---|
| Charleston | Charleston | Area 10 |
| Greenville | Greenville | Area 23 |
| Horry | Myrtle Beach | Area 26 |
| Lexington | Lexington | Area 32 |
| Richland | Columbia | Area 40 |
| Spartanburg | Spartanburg | Area 42 |
| York | Rock Hill | Area 46 |
Sources: Centers for Medicare and Medicaid Services, South Carolina geographic rating areas (46 areas, one per county); 45 CFR 147.102 ("in the small group market, using the group policyholder's principal business address"). The city column is mine, for orientation.
So the same crew can be priced differently from an office in Charleston, a shop in Greenville, and a yard in Rock Hill. Which companies will quote your address is something I check case by case, and I don't recommend one over another on a web page. I don't have a South Carolina office. One page, real numbers, and a phone or Zoom call when you want your own.
Affordable small business health insurance in South Carolina: which situation are you in?
Two to fifteen employees, mostly young and healthy, owner wants to keep costs down
Price routes 2 and 3 against a traditional group quote. Put all three on one page. On a young team the group plan is often the most expensive of the three.
An older team, or someone with a serious diagnosis in the last five years
Guaranteed-issue coverage, for now. Traditional small group asks no health questions and cannot charge more for a condition. We revisit the other routes at renewal.
Half the team is on a spouse's plan and the rest want coverage
Check the participation rule before you quote. Federal rules give a small employer that cannot meet it an annual window, November 15 through December 15, when a company has to take the group anyway (45 CFR 147.104). Routes 2 and 3 cover only the people who want it, with no participation test.
Lower-wage team, mostly part-time or 1099
A group plan may not fit, and I will tell you so. For a lower-income worker, a subsidized marketplace plan may be the best deal available. The trade-offs: they have to check the network for their doctors, and the income estimate has to be right. My subsidy calculator shows where the income lines fall.
SHOP and the small business tax credit in South Carolina: the reality
SHOP is the small business side of the exchange. South Carolina does not run its own. The Department of Insurance describes SHOP as "the small group health insurance exchange that the federal government established in South Carolina." On paper the federal rules are simple: 1 to 50 FTEs with at least one who is not an owner, spouse, family member, or partner, an office or work site in the state, an offer to every full-time employee, and at least 70% of the people you offer it to enrolled. There is no enrollment window, and you enroll with the insurance company directly or through a SHOP-registered agent.
Here is the catch. The Department's 2026 small group rate summary has a table for companies offering plans through SHOP, and it holds one line: "No FF-SHOP Issuers for 2026." Its Affordable Care Act page says all small group plans are "sold strictly through the private market." I have not seen a 2027 list yet.
That matters for the Small Business Health Care Tax Credit. HealthCare.gov says it plainly: "Enrolling in SHOP insurance is generally the only way for eligible small employers to take advantage of the Small Business Health Care Tax Credit." The IRS rules on top of that: fewer than 25 FTEs, average wages under an inflation-adjusted limit (for tax years beginning in 2026 the credit starts to shrink once average wages pass $34,100 and is gone at double that, per IRS Rev. Proc. 2025-32), and a uniform employer contribution of at least 50% of the premium. The credit is worth up to 50% of the premiums you pay (35% for a tax-exempt employer), for two consecutive tax years (IRS Form 8941 instructions, 2025 form). With no SHOP plans listed, I would not count on the credit in South Carolina. The IRS relief for counties with no SHOP plans only helps an employer that already claimed the credit the year before, so ask your tax professional before you plan around it.

When someone leaves: COBRA and South Carolina's six-month rule
A group plan comes with an exit rule. Federal COBRA does not apply to a plan when the employer "normally employed fewer than 20 employees" in the prior year (29 U.S.C. 1161). South Carolina fills part of that gap. A group policy issued in South Carolina has to let an employee who was insured continuously for at least six months keep the coverage for the rest of the policy month plus six more policy months, when the coverage ends for any reason other than not paying the premium. The employee pays the entire group premium, including the part you used to pay, before each policy month begins. It does not apply to someone who is eligible for other group coverage with similar benefits or for Medicare, or who has a longer continuation right under federal law. When an employee leaves, you have to tell them about the right, the premium amount, and the monthly due date (South Carolina Code 38-71-770). On routes 2 and 3 the person owns the policy, so ask me how leaving the company works on each one.
Common questions about small business health insurance in South Carolina
Is a small business in South Carolina required to offer health insurance?
Not with fewer than 50 full-time equivalent employees, and there is no penalty for skipping it. At an average of 50 or more full-time and full-time equivalent employees, the federal employer mandate applies. For 2027 the IRS penalties are $3,780 per full-time employee, not counting the first 30, for not offering coverage, and $5,670 for each full-time employee who gets a marketplace tax credit when the coverage is unaffordable or falls short (for 2026: $3,340 and $5,010). Either one applies only if at least one full-time employee gets that credit. Affordable means the employee's required contribution is no more than 10.22% of household income for 2027 plan years (9.96% for 2026).
How much does small business health insurance cost in South Carolina?
For 2025, the federal MEPS-IC employer survey put the average annual premium for employer coverage in South Carolina at $8,552 for single, $16,317 for employee-plus-one, and $25,046 for family. Employees paid an average of $1,814 of the single premium and $8,269 of the family premium. Those averages cover employers of all sizes, so treat them as a benchmark, not a quote.
How much are South Carolina small group health insurance rates going up for 2027?
As of October 3, 2026, the 2027 rates are proposed, not approved. The federal rate review site lists five South Carolina small group filings for 2027, all marked Pending Review, with proposed average increases from 5.96% to 11.50% depending on the company. For 2026, the South Carolina Department of Insurance approved average increases from 8.08% to 11.80% by company, and a 10.93% average weighted by written premium.
Do I have to pay a percentage of my employees' premiums in South Carolina?
The contribution and participation rules on a South Carolina small group plan come from the insurance company, so get them in writing before you quote. My advice on a group plan: pick a flat dollar amount per person that you can budget, not a percentage, as long as it clears the company's contribution minimum. If you want the federal tax credit, the IRS generally requires a uniform percentage of at least 50%.
Can a business owner with no employees get group health insurance in South Carolina?
Generally no. The South Carolina Department of Insurance says the small group market includes small employers with 2 to 50 employees, and that people who are self-employed or have no employees are generally not able to buy small group coverage. A solo owner can be merged into a pre-established ERISA group plan or buy a customized individual plan.
Can a South Carolina small business claim the small business health care tax credit?
Do not count on it. The credit generally requires a SHOP plan, and the South Carolina Department of Insurance listed no SHOP issuers for 2026. The IRS also requires fewer than 25 full-time equivalent employees, average wages under its limit, and an employer contribution of at least 50%. Ask your tax professional whether any exception applies to you.
What happens to an employee's coverage when they leave a South Carolina small business?
Federal COBRA does not apply when the employer normally had fewer than 20 employees. South Carolina law then requires a group policy to let an employee who was insured continuously for at least six months keep the coverage for the rest of the policy month plus six more policy months. The employee pays the entire group premium, including the part the employer used to pay. It does not apply to someone who is eligible for other group coverage with similar benefits or for Medicare.
What is the cheapest way to cover a small team in South Carolina?
It depends on the team. A small group plan cannot price on health, so a young, healthy crew pays the pool's average, and a pre-established ERISA group plan or customized individual plans often cost less. An older team, or one with a serious diagnosis, usually belongs in a traditional fully insured small group plan. Put all three routes side by side before you sign.
