What is workers' comp class code 5191?

Class code 5191 (Office Machine Installation, Inspection, Adjustment, or Repair) is an NCCI workers' compensation classification in the Services industry group.

Hazard group: E.

How much is workers' comp insurance for class code 5191?

It depends on the state, and only some states publish a per-class figure. For class code 5191, the filed figures per $100 of payroll are: Wisconsin $0.848 (rate, WCRB, effective 2026-10-01); New York $0.880 (loss cost, NYCIRB, effective 2026-10-01). A loss cost is not a rate — your insurer multiplies it by its own loss cost multiplier — and every figure is before your experience modification. For other states this site shows a relative cost index, not a dollar figure. North Dakota, Ohio, Washington and Wyoming are not included. Each is a monopolistic state fund that sets premium on its own basis rather than on an NCCI class-code rate per $100 of payroll, so there is no comparable figure to average or rank.
