Oklahoma business insurance: requirements and costs

Oklahoma sets no minimum headcount for workers' comp: any employer with an employee must carry it unless a statutory exclusion applies, such as a business whose five or fewer employees are all close relatives.⁠3 NCCI files loss costs for the private market, and the Oklahoma Insurance Department approved a 9.2% decrease for policies starting January 1, 2025, following a 71% fall since 2011.⁠1 Oklahoma's manual rates still rank 15th most expensive of 51 jurisdictions in Oregon's 2024 study, though actual employer cost has been falling.⁠9⁠8

Workers' comp is sold by private insurers. NCCI is the licensed advisory organization that files recommended loss costs, the part of a rate that covers claims, for the Oklahoma Insurance Department (OID) to approve; each insurer then applies its own multiplier for expenses and profit.⁠1 NCCI's filing also covers the assigned risk plan, the pool for employers that cannot find a voluntary carrier.⁠2 Employers can also self-insure with proof of financial ability and security, or through a group self-insurance association.⁠5 The Oklahoma Workers' Compensation Commission administers claims and, if an employer fails to secure coverage, can assert the injured employee's rights against that employer.⁠5

The latest OID decision we could confirm is the 9.2% loss-cost decrease effective January 1, 2025.⁠1 NCCI then filed on September 18, 2025 for a further 4.7% decrease in voluntary loss costs and assigned risk rates effective January 1, 2026, based on policy years 2022 and 2023 valued at year-end 2024.⁠2 We could not confirm OID's decision on that filing, so treat 4.7% as a proposal. Loss costs are not the premium you pay. If an insurer's multiplier stayed unchanged and your class moved exactly 9.2%, our calculation shows a $20,000 policy would renew at about $18,160 with no change in payroll or experience mod; your class code can move more or less. NASI's employer-cost series shows the same direction: Oklahoma employers paid $0.91 per $100 of covered wages in 2023, down from $1.10 in 2019, a 17% drop by our calculation, against a 16% national drop to $0.98.⁠8 Oregon's index, built from manual rates in effect January 1, 2024, puts Oklahoma at $1.33 per $100 of payroll, 122% of the median state. Missouri is close ($1.31, 16th), while Texas ($0.78), Kansas ($0.91) and Arkansas ($0.53) are cheaper.⁠9

Two statutory details change how you buy. A prime contractor is liable for the compensation of a subcontractor's employees if the subcontractor has no coverage, unless an intermediate subcontractor does, and a subcontractor that is not required to carry coverage can file an Affidavit of Exempt Status with the Commission to shift that exposure.⁠4 Separately, SB 1944 raises the payroll test for the agricultural exclusion from $150,000 to $250,000 of prior-year farm wages, effective November 1, 2026; separately, farm workers who do not operate motorized machines are excluded at any payroll.⁠3 For health benefits, AHRQ's 2025 survey found 37.2% of Oklahoma private establishments with fewer than 50 employees offered coverage, against 32.1% nationally. Where offered, the average single premium for those small firms was $8,231 against $9,034 nationally (about 9% lower by our calculation), and employees paid $1,750 against $1,924.⁠10

Workers’ compensation in Oklahoma

Every employer with an employee must secure compensation unless an exclusion applies; the statute sets no numeric threshold.⁠3⁠5 The definition of employee excludes, among others, workers of an employer with five or fewer employees who are all relatives within the second degree or household dependents.⁠3

Who is exempt

  • Employer with five or fewer employees, all related to the employer within the second degree by blood or marriage, all household dependents, or a mix of both
  • Sole proprietors, partners, franchisees, LLC members owning at least 10% and stockholder-employees owning at least 10%, unless they elect to be covered
  • Agricultural, ranching or horticultural workers of an employer with under $150,000 of prior-year payroll for such workers (rising to $250,000 on November 1, 2026), or any such worker who does not operate motorized machines
  • Domestic servants and casual workers in a private home with under $50,000 of prior-year payroll for such workers
  • Commission-paid licensed real estate sales associates and brokers
  • Truck owner-operators who operate their own truck, when the contracting party is not the lessor, and drive-away owner-operators on similar terms
  • Volunteers who receive no wages beyond meals, lodging, transportation or reimbursed expenses, and employees of qualifying youth sports leagues

Buying coverage and who sets the rates

Buy from a licensed private insurer, self-insure individually or through a group self-insurance association, or use the assigned risk plan if no voluntary carrier will write you.⁠2⁠5 The statute allows individual self-insurance with a surety bond or letter of credit.⁠5

Latest rate decision (1 Jan 2025): The Oklahoma Insurance Commissioner approved a 9.2% decrease in workers' compensation loss costs for new and renewing policies effective January 1, 2025. NCCI has since proposed a 4.7% decrease effective January 1, 2026; we could not confirm OID's decision. Official notice.

Allowed for an individual employer with proof of financial ability and security (a surety bond or irrevocable letter of credit), or through a group self-insurance association of two or more employers.⁠5

Penalties for going without

An employer that fails to secure compensation lets the Commission assert the injured employee's rights against it.⁠5 Knowingly giving false information to obtain a self-insurance permit is a Class D3 felony with a fine up to $10,000, and a knowingly false Affidavit of Exempt Status is a misdemeanor with a fine up to $1,000.⁠4⁠5 The security section we opened (85A s. 38) names no fine for going uninsured; we did not review the rest of the Act for other penalties.

Oregon’s biennial comparison of workers’ comp rates puts Oklahoma’s index for rates in effect on 1 January 2024 at $1.33 per $100 of payroll, 22% above the national median of $1.09 (rank 15 of 51, where 1 is the most expensive). The index prices the same 50 risk classes, weighted by Oregon payroll, in every state, so it compares rate levels rather than what employers actually pay. Compare every state.

Commercial auto in Oklahoma

Every vehicle registered in Oklahoma, including business vehicles, must carry at least 25/50/25 in liability limits (bodily injury per person / per accident / property damage, in thousands of dollars). Official source.

Every owner of a vehicle registered in Oklahoma must keep security for liability for bodily injury, death and property damage, and the Insurance Department states the minimum as $25,000 per person, $50,000 per accident and $25,000 property damage.⁠6⁠7 Oklahoma is not a no-fault state and we found no PIP requirement. We did not research separate commercial or for-hire minimums.

Trucks and buses used in interstate commerce must also meet federal minimums of $750,000 to $5 million: see commercial auto minimums and what commercial auto costs.

Other Oklahoma rules that affect insurance costs

Prime contractors answer for uninsured subcontractors

If a subcontractor fails to secure compensation, the prime contractor is liable for its employees unless an intermediate subcontractor has coverage. The prime can recover from the subcontractor, and that claim is a lien on money owed to it.⁠4 A subcontractor with an unexpired Affidavit of Exempt Status on file is conclusively presumed not covered, and the prime's carrier does not count payments to it in the prime's premium.⁠4

Farm exclusion changes November 1, 2026

Under 85A s. 2 as amended by SB 1944, the prior-year farm payroll below which agricultural, ranching and horticultural employees are excluded rises from $150,000 to $250,000 on November 1, 2026. Separately, workers who do not operate motorized machines are excluded at any payroll, so the payroll test matters mainly for tractor and equipment operators.⁠3
