Best Workers' Comp Insurance in South Carolina (2026)

ERGO NEXT leads our rankings for workers' comp insurance in South Carolina with excellent customer support and broad coverage options. Nationwide and The Hartford round out the top three, both providing strong alternatives for South Carolina small business owners.

Nationwide and ERGO NEXT tie as South Carolina’s cheapest workers’ comp providers at about $77 per month ($924 annually), roughly 25% below the state average of $102. Thimble follows at $90 per month, giving small businesses several competitively priced options in the state.

The difference between low-cost and high-cost carriers can be substantial. For example, the gap between Nationwide ($77/month) and Chubb ($141/month) creates roughly $768 in annual savings per employee. These savings benefit lower-risk businesses with clean claims histories most, while pricing differences narrow in higher-risk industries where there is less competition and underwriting factors play a larger role.

There’s a clear price leader in South Carolina based on our analysis. ERGO NEXT offers the lowest workers’ comp rates in 19 of the 25 industries reviewed, spanning both white-collar and physically demanding industries. The Hartford delivers the cheapest pricing in five industries, including Healthcare and Medical and Tech and IT, while biBerk leads only in Childcare Services.

The pricing split reflects how carriers specialize by risk profile. ERGO NEXT tends to price more aggressively in labor-intensive industries like construction and transportation, while The Hartford is generally more competitive in lower-risk professional sectors.

The most striking pattern in our analysis of South Carolina’s workers’ comp market is the wide pricing gap between industries. Beauty and wellness businesses average about $15 per employee monthly, while transportation and logistics companies average roughly $308. That difference is driven largely by each industry’s injury risk and claims frequency under NCCI classification codes.

South Carolina’s average workers’ comp cost of about $102 per month sits well above the national average of $74, largely because industries like manufacturing, construction and logistics make up a larger share of the state’s workforce. Businesses in lower-risk office or service sectors pay rates much closer to, or even below, national averages for their classification.

South Carolina workers' comp rates are filed and regulated through the National Council on Compensation Insurance (NCCI) under oversight of the South Carolina Department of Insurance. The state's private competitive market means employers can shop multiple carriers, but NCCI class codes and the state's above-average industrial injury profile drive the baseline cost above the national average of $74/month.

South Carolina law mandates workers' compensation insurance if you employ four or more people and have at least $3,000 in annual payroll. Required workers' compensation coverage in South Carolina has no dollar limits. Policies must cover full medical treatment, two-thirds of injured workers' wages up to $1,189.94 weekly and permanent disability benefits ranging from weeks to a lifetime, depending on injury severity.

Coverage amounts scale with your payroll and industry risk. Insurers calculate premiums per $100 of payroll based on your classification code. Operating without coverage triggers the Uninsured Employers Fund, which places bankruptcy-proof liens against all business assets.

Some categories are exempt from workers' comp requirements:

• Small businesses with three or fewer employees: These don't need workers' comp coverage, whether employees work part-time or full-time.
• Annual payroll below $3,000: Businesses are exempt if their total annual payroll stayed under $3,000 in the previous calendar year.
• Agricultural operations: Farming businesses and their workers aren't covered under South Carolina's workers' comp requirements.

• Business owners and partners: Sole proprietors, business partners and LLC members are automatically excluded from coverage but can add themselves to policies by contacting insurers.
• Corporate officers: Corporate officers get coverage under company policies, though they can opt out by filing the Corporate Officer's Notice to Reject form with insurers.
• Casual and irregular workers: Workers hired for tasks outside regular business operations don't require coverage.
• Self-employed business owners: Self-employed individuals without employees are exempt from workers' comp requirements.
