Are you liable for an uninsured sub in New Mexico?
Many states make a hiring contractor responsible for an uninsured subcontractor’s injured workers. Ask the New Mexico Workers’ Compensation Administration or an attorney how that works in New Mexico.
Separately, your own workers’ comp premium auditor may charge you for an uninsured sub’s payroll. Collecting a current certificate for every sub is the simplest protection. See workers’ comp audits and uninsured subcontractors, or estimate the cost with the workers’ comp audit calculator.
