Best Workers' Comp Insurance in South Dakota (2026)

The Hartford offers the best workers' comp insurance in South Dakota at the lowest available rate, with strong customer experience and coverage options. ERGO NEXT and Nationwide are strong alternatives for employers who want competitive pricing with solid coverage.

The Hartford is South Dakota's cheapest workers' comp provider at $52 a month ($624/year). Nationwide ties that rate, while ERGO NEXT follows closely at $54 a month, giving South Dakota employers three competitive options at the low end of the market.

The $36 monthly gap between the cheapest provider in our analysis (The Hartford at $52) and the most expensive (Chubb at $88) adds up to $432 per employee annually. For a four-person business, that amounts to $1,728, highlighting the importance of comparison shopping before purchasing a policy.

The Hartford has the cheapest rates in 11 of the 25 industries we analyzed in South Dakota, though its wins are concentrated in lower-cost sectors where rates stay at $75 per month or less. ERGO NEXT leads in 13 industries, including all five of the highest-cost categories we reviewed.

Businesses in construction, transportation, wholesale, agriculture and cleaning will generally find the most competitive pricing with ERGO NEXT, while The Hartford has the strongest value for office-based and lower-risk industries. Coverdash leads in just one category, childcare, with rates starting at $21 per month, matching The Hartford’s pricing for hospitality and tech businesses.

South Dakota workers’ comp rates average $65 per month per employee, $9 below the national average of $74. But costs vary widely by industry. Marketing and communications businesses average just $13 monthly, while transportation and logistics companies average $193.

That $180-per-month gap shows how industry risk drives pricing more than statewide averages do. South Dakota's cost advantage is strongest for office-based and service industries. It narrows for physical-labor sectors where rates follow national NCCI risk models.

South Dakota workers' comp rates are filed and regulated through the South Dakota Division of Insurance using NCCI class codes. South Dakota's private competitive market lets employers compare rates across multiple carriers. A relatively low average wage base in many industries keeps South Dakota's costs below the national average.

South Dakota law doesn't require workers' compensation coverage, making it one of only two states where coverage remains voluntary. However, injured employees can sue you for medical expenses plus twice the disability income or death benefits allowed under state law.

A South Dakota workers' comp policy must provide full medical care with no dollar limits, temporary disability benefits equal to two-thirds of average weekly wages and permanent disability benefits. Coverage amounts depend on payroll and industry classification codes.

In South Dakota, workers' compensation insurance is voluntary for most employers. If an employer carries a policy, though, certain occupations and business owners are exempt from workers' comp requirements:

• Farm and agricultural workers: South Dakota excludes farm and agricultural laborers from workers' comp requirements regardless of hours worked or employee count.
• Domestic servants: Household employees working fewer than 20 hours per week and fewer than six weeks in any 13-week period are exempt from coverage in South Dakota.
• Sole proprietors: Sole proprietors are automatically excluded from South Dakota workers' comp requirements but can elect coverage voluntarily using the state's minimum payroll of $54,600 for rating.
• Business partners: Partners in partnerships are automatically exempt from coverage under South Dakota law but can choose to be included at the minimum payroll rate.
• Corporate officers: South Dakota automatically includes corporate officers in workers' comp coverage but allows them to opt out by filing exemption paperwork with their carrier.
• LLC members: South Dakota treats LLC members like corporate officers. They're automatically covered but can elect exemption by filing the appropriate forms.
• Independent contractors: An independent contractor whose work falls outside the usual course of the employer's business is exempt, including South Dakota-certified real estate agents and truck owner-operators.
• Self-employed individuals: Self-employed business owners without employees aren't required to carry workers' comp in South Dakota, but can purchase it voluntarily for personal protection.
• Workfare participants: South Dakota excludes individuals participating in government workfare programs from workers' comp requirements.
• Elected officials: Officials elected to serve South Dakota or any political subdivision are exempt from mandatory workers' comp coverage.
