Are you liable for an uninsured sub in Iowa?
Many states make a hiring contractor responsible for an uninsured subcontractor’s injured workers. Ask the Iowa Division of Workers’ Compensation or an attorney how that works in Iowa.
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.
What to collect from subcontractors in Iowa
- A certificate of insurance, usually an ACORD 25, showing GL, auto, umbrella and workers’ comp.
- Exemption paperwork for sole proprietors or officers who claim they don’t need workers’ comp under Iowa rules.
- Additional insured and waiver of subrogation endorsements for higher-risk trades. See waiver of subrogation on workers’ comp.
- A renewal certificate before each policy expires. See COI expiration.
