Filing checklist for Manufacturing businesses in Illinois
-
Step 1, Confirm coverage threshold
All employers with one or more employees are required to carry workers' compensation insurance. For Manufacturing operations, this typically applies once you make a first W-2 hire, even part-time.
-
Step 2, Pick the right class code
Manufacturing businesses typically use codes like 6872, 3081, 3085. The wrong code can cost 4 to 10x more or get reclassified at audit. In Illinois, the cheapest code on this list is 1701 at $1.98 and the most expensive is 3081 at $4.90.
-
Step 3, Get a quote
Private carriers write Manufacturing coverage in Illinois. Schedule credits up to 25% are typical for low-loss accounts.
-
Step 4, Document subcontractors
General contractors are liable for the workers' compensation coverage of uninsured subcontractors. Manufacturing 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. Manufacturing class allocation can shift if any worker spends more than 50% of time on a different code.
