Frequently Asked Questions
Is workers' comp required for manufacturing employers in Wisconsin?
Yes — Wisconsin requires workers' comp once you have 3+ employees, and manufacturing almost always triggers coverage requirements from day one. Coverage is available via any authorized Wisconsin carrier — we shop multiple A-rated markets to find the best rate for your class codes.
What class codes usually apply to manufacturing operations in Wisconsin?
varies by product — NCCI codes 3632, 2501, 3076, 3400 common. WCRB sets the exact rates for Wisconsin. Class code assignment is the single biggest cost lever in manufacturing WC — misclassification (whether intentional or accidental) is the #1 audit finding we see and can cost thousands per year.
How can Wisconsin manufacturing employers lower their WC premium?
Four levers work in Wisconsin: (1) accurate class-code assignment with clean payroll separation by role, (2) a written return-to-work program that minimizes indemnity payouts, (3) diligent subcontractor COI tracking so uninsured sub payroll doesn't roll into your audit, and (4) shopping multiple carriers at each renewal — WCRB sets loss costs but individual carrier rate deviations vary significantly.
