Filing checklist for Construction businesses in Colorado
-
Step 1, Confirm coverage threshold
All businesses with employees, regardless of number of employees, part-time status, or family relation. 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. Across reporting states, Construction median rates run $2.26 per $100 with a range of $0.032 to $53.88.
-
Step 3, Get a quote
Pinnacol Assurance is one option in Colorado; 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 principal contractor is generally liable for injuries to employees of uninsured subcontractors. 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.
