Frequently Asked Questions
Is workers' comp required for construction employers in Wisconsin?
Yes — Wisconsin requires workers' comp once you have 3+ employees, and construction 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 construction operations in Wisconsin?
NCCI codes 5403, 5645, 5606, 5213 (carpentry, framing, exec, concrete). WCRB sets the exact rates for Wisconsin. Class code assignment is the single biggest cost lever in construction WC — misclassification (whether intentional or accidental) is the #1 audit finding we see and can cost thousands per year.
How can Wisconsin construction 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.
