Filing checklist for Construction businesses in Alabama
-

-
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 Alabama, the cheapest code on this list is 5191 at $0.560 and the most expensive is 7335 M at $1.54.
-
Step 3, Get a quote
Private carriers write Construction coverage in Alabama. Schedule credits up to 25% are typical for low-loss accounts.
-
Step 4, Document subcontractors
General contractors can be held 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.
