What Makes South Carolina Unique

South Carolina's growing manufacturing sector — including BMW, Volvo, Boeing, and numerous automotive suppliers — has created a large employer market for workers' comp. South Carolina's relatively business-friendly environment and moderate workers' comp rates have been factors in attracting manufacturing investment.

Who Sets Workers’ Comp Rates in South Carolina

South Carolina is an NCCI state. NCCI files advisory loss costs and class codes, and each insurer applies its own approved multiplier, plus schedule credits or debits, to arrive at your rate. That’s why quotes on identical payroll and class codes can differ meaningfully in South Carolina, and why comparing carriers at renewal is worth the effort. Our blended estimate of about $1.62 per $100 of payroll hides an enormous range — clerical work is typically a small fraction of that, roofing many times more.

When Coverage Becomes Mandatory in South Carolina

South Carolina requires coverage for employers with four or more employees and an annual payroll above $3,000 in the prior year. Owners crossing the threshold should arrange coverage before the hire that triggers it, not after — an injury in the gap is the employer’s to pay in full.

South Carolina’s Maximum Weekly Benefit

Injured workers in South Carolina receive wage-loss benefits based on their average weekly wage, up to a statutory cap. The maximum weekly benefit is $1,178.30, effective January 1, 2026 (Social Security Administration chart of state maximums). The cap matters for employers with well-paid staff: a claim by a high earner is paid at the maximum, so lost-time claims from skilled trades and professionals cost more than claims from lower-wage roles — one reason the experience modifier responds so strongly to a single serious claim.
