Oklahoma facts employers ask about
Oklahoma moved from a court-based system to an administrative one in 2014. Claims arising after that change are handled by the Oklahoma Workers' Compensation Commission. Most employers with one or more employees must carry coverage; exceptions include some agricultural employers and very small family-run businesses.
CompSource Mutual Insurance Company, the former state fund, competes with private insurers. Oklahoma uses NCCI classifications. Contractors who use subcontractors should collect certificates, because an uninsured subcontractor's workers can be charged to the hiring contractor's policy at audit.
Oklahoma's energy, construction and trucking sectors generate many higher-hazard classes. Payroll for oilfield service work, drivers and office staff should be separated carefully so each employee is rated in the correct class.
Under the Administrative Workers' Compensation Act, Oklahoma also allows qualifying employers to adopt an approved benefit plan in place of standard coverage under the opt-out provisions, but parts of that law were struck down by the Oklahoma Supreme Court, so employers should not rely on an opt-out arrangement without current legal advice.
