Filing checklist for Construction businesses in Oklahoma
-
Step 1, Confirm coverage threshold
Employers with one or more employees are generally required to carry workers' compensation insurance. For Construction operations, this typically applies once you make a first W-2 hire, even part-time.
-
Step 2, Pick the right class code
Construction businesses typically use codes like 7335, 6251, 6252. The wrong code can cost 4 to 10x more or get reclassified at audit. In Oklahoma, the cheapest code on this list is 5191 at $0.690 and the most expensive is 6252 at $1.66.
-
Step 3, Get a quote
CompSource Mutual Insurance Company is one option in Oklahoma; private carriers (Travelers, Hartford, Liberty Mutual, AmTrust) also write coverage. Schedule credits up to 25% are typical for low-loss accounts.
-
Step 4, Document subcontractors
A general contractor is liable for the workers' compensation coverage of uninsured subcontractors and their employees. Construction operators with crews of 1099s should keep certificates of insurance for every sub, otherwise the GC absorbs the sub liability at audit.
-
Step 5, Annual audit
Carriers audit payroll within 90 days of policy expiration. Have payroll segregated by class code, job descriptions on file, and overtime properly excluded from rated payroll. Construction class allocation can shift if any worker spends more than 50% of time on a different code.
