What Makes Wisconsin Unique

Wisconsin's workers' comp system includes a payroll threshold that can capture very small employers even below the 3-employee threshold. Wisconsin's system is known for relatively efficient administration and a functional dispute resolution process that does not heavily favor either employers or employees.

Who Sets Workers’ Comp Rates in Wisconsin

Wisconsin doesn’t use NCCI for ratemaking. Rates and classifications come from the Wisconsin Compensation Rating Bureau (WCRB), an independent rating bureau, and Wisconsin’s class codes and rules can differ from those used in NCCI states. Employers operating in several states should expect a Wisconsin class code that doesn’t match the code on their other policies, and should check it at every audit.

When Coverage Becomes Mandatory in Wisconsin

Wisconsin requires coverage once an employer has three or more employees — or any employee if it paid $500 or more in wages in any calendar quarter. Owners crossing the threshold should arrange coverage before the hire that triggers it, not after — an injury in the gap is the employer’s to pay in full.
