If you’re a general contractor in Utah, your subcontractors are your biggest workers comp liability — and most GCs don’t find out until the audit or the claim. This guide covers everything you need to know about sub compliance in Utah, what the law actually says, and how to protect your business without building a full-time compliance department.
Under the Utah Workers Compensation Act, if a subcontractor you hire doesn’t carry their own workers comp coverage, they legally become your employee for WC purposes. You are liable for their injuries and claims — period. This applies to sole proprietors, corporate officers, and LLCs who haven’t secured coverage or filed a proper waiver.
General contractors manage relationships with dozens — sometimes hundreds — of subcontractors across multiple project types. Each sub has their own WC policy with its own carrier, renewal date, and coverage terms. What looked compliant at project kickoff may have lapsed by month three.
The common failure points:
Not every certificate of insurance is adequate. For Utah workers comp compliance, a valid COI should include:
A common mistake: accepting a COI that names someone else as certificate holder, or a COI for general liability without WC. Neither protects you.
Utah allows some sole proprietors to file a Workers Compensation Coverage Waiver (WCCW) with the Utah Labor Commission. A waiver means the individual has formally waived their right to WC benefits.
Important: there is no WC exemption for construction contractors who have employees. The exemption only applies to sole proprietors with no employees who are doing the work themselves.
If a sub claims exemption:
The GCs who handle this well don’t rely on memory or informal processes. They build a system:
Before a sub steps on your job site, require submission of: current COI for WC and general liability, business license, any required trade licenses, and signed subcontract agreement that includes WC verification language.
Use a spreadsheet or project management tool to track the expiration date of every sub’s WC policy. Set calendar reminders 30 days before expiration to request updated COIs.
Call the insurance carrier listed on the COI to verify the policy is active. Takes 5 minutes and has saved GCs from significant liability. Many carriers have online verification portals.
Your subcontract agreement should explicitly state: (a) sub must maintain WC coverage for all employees, (b) sub must provide updated COI if coverage changes, and (c) sub’s failure to maintain WC coverage is grounds for immediate removal from the project.
We help Utah GCs manage sub compliance, WC, and payroll — free advisory service.
Every workers comp policy is subject to annual audit. Your carrier reviews your actual payroll against the estimated payroll used to calculate your initial premium. During this audit, they will also look at your subcontractor payments.
If you paid a sub and don’t have a valid COI on file proving they had WC coverage, the auditor will include that sub’s payroll in your total — and charge you WC premium on it at your classification rate. For a roofing GC at $15–$25 per $100 of payroll, an unverified sub payment of $50,000 could result in $7,500–$12,500 in unexpected WC premium.
The defense: an organized COI file with valid, current certificates for every sub you paid during the policy period.
For GCs whose own employees are run through a PEO, sub compliance is only one part of the WC picture — the other part is ensuring your own workers are properly classified and covered. A PEO provides:
