Rates by State for Class Code 5191

47 jurisdictions rate this code per $100 of payroll. 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.

About Class Code 5191: Scope, Inclusions, and Common Misclassifications

NCCI Class Code 5191 — officially phrased "Office Machine Installation, Inspection, Adjustment, or Repair" — is the workers' compensation classification for businesses that install, service, and repair office machines and computer equipment. It contemplates work on all types of office machines including calculators, computers and computer-related equipment (modems, printers, scanners), copy machines, fax machines, microfilm equipment, postage machines, and point-of-sale or transactional devices such as ATMs, credit-card readers, and electronic cash registers. The classification anticipates that the insured performs work away from its own shop — on the customer's premises as well as in the shop — and it includes the dead-wiring work needed up to the point of plugging the machine into a live circuit, plus disassembling, replacing parts, reassembling, and cleaning the equipment.

5191 sits in hazard group E and carries a service-and-repair exposure built around technicians who travel between customer sites, carry tools and parts, and lift and position equipment. It is frequently confused with electrical-construction codes because both involve some wiring, but 5191 is light field service for office and computer hardware — not the building-wiring work that rates to 5190 Electrical Wiring — Within Buildings. This page compares filed base-rate estimates for 5191 across states so an office-machine, copier, or IT-hardware service company can see the spread before requesting a quote; the figure shown is an illustrative benchmark, not a binding quote.

What's Included Under Class Code 5191

NCCI assigns 5191 to the installation, inspection, adjustment, or repair of office machines and computer equipment performed by a service business that does not retail new equipment. Covered operations include setting up and servicing computers and peripherals (printers, scanners, modems), copiers and multifunction devices, fax machines, calculators, postage and microfilm equipment, and point-of-sale or transactional hardware such as cash registers, payment terminals, credit-card readers, and ATMs. To qualify for 5191, an insured must engage in operations away from its own shop; the code then covers all work done on the customer's premises as well as bench work back in the shop.

The classification includes the low-voltage and dead-wiring work necessary to connect a machine up to the point of plugging it into a live wire circuit, along with disassembling the equipment, replacing parts, reassembling, and cleaning. It does not extend to wiring the building itself: running branch circuits, panels, or fixed power and lighting wiring is electrical-construction work classified to 5190, not 5191.

5191 vs 5190, 8859, and 8810 — Service Hardware Is Not Construction or Software

The most common boundary error is treating 5191 as an electrical-wiring code. They are different classifications: 5190 Electrical Wiring — Within Buildings covers electricians installing the building's wiring systems — power and lighting circuitry, fuses, plugs, and switches — while 5191 covers technicians who service office machines and computer hardware and only run the short low-voltage lead from the equipment to its power source. If a worker is wiring the building, the work is 5190; if a worker is installing or repairing the machine that plugs into the building, the work is 5191. A site audit that finds branch-circuit or panel work being reported under 5191 will reclassify it.

Two other boundaries matter for technology businesses. Writing or maintaining software, programming, and systems-analysis work rates to 8859 Computer Programming or Software Development, not 5191 — 5191 is hands-on hardware service, not coding. And the office staff who schedule jobs, dispatch technicians, and handle billing are clerical: whether their payroll can be separately rated to 8810 Clerical Office Employees instead of being absorbed into the 5191 field payroll depends on the governing state bureau's standard-exception rules, so confirm the state's treatment before assuming a clerical split.

Audit Records for 5191 Office Machine Service

The audit file that protects a 5191 assignment documents that the work is office-machine and computer-hardware service performed at customer sites and in the shop — not building electrical wiring. Keep service tickets or work orders describing the equipment serviced (copiers, printers, computers, POS terminals), payroll detail for field technicians, and records separating any building-wiring or low-voltage cabling subcontract work that belongs in a construction code. If technicians both service machines and perform separately rated electrical-construction work, divide payroll so each duty maps to its correct classification.

Travel between customer sites is part of the 5191 exposure, so vehicle and route records help substantiate the field-service nature of the work. For quote shoppers, the rate table on this page is a benchmark, not a binding quote: the filed base-rate estimate still changes after payroll, the carrier's loss-cost multiplier, the employer's experience modification factor, schedule credits, minimum premium, and any reclassification to a construction or programming code. Independent-bureau states publish their own 5191 phraseology and rates, so an operator in a state with its own rating bureau should confirm the local classification rather than rely on a single national figure.

Is class code 5191 the same as electrical wiring code 5190?
No. NCCI 5191 is "Office Machine Installation, Inspection, Adjustment, or Repair" — light field service for computers, printers, copiers, and point-of-sale hardware. Electrical wiring of buildings (branch circuits, panels, power and lighting wiring) is a separate classification, 5190 Electrical Wiring — Within Buildings. 5191 only includes the short low-voltage lead from the equipment to its power source; wiring the building itself is 5190. A page or quote that labels 5191 as commercial electrical wiring has conflated the two codes.
Does code 5191 cover computer and IT equipment repair?
Yes. 5191 contemplates installing, inspecting, adjusting, and repairing computers and computer-related equipment — including modems, printers, scanners, and other peripherals — along with copiers, fax machines, calculators, postage and microfilm machines. The work covers disassembling the equipment, replacing parts, reassembling, and cleaning, on the customer's premises and in the shop. Writing or maintaining the software itself, however, is computer programming and rates to code 8859, not 5191.
Does 5191 include point-of-sale (POS) and ATM service?
Yes. The classification applies to the installation, service, or repair of point-of-sale and transactional machines, including automated teller machines (ATMs), credit-card readers, payment terminals, electronic cash registers, and similar electronic transaction devices, in addition to traditional office machines.

What is the workers' comp rate for class code 5191?
There is no single national 5191 rate — workers' comp rates are filed per state, and 5191 base-rate estimates vary by state rating bureau, then change again after the carrier's loss-cost multiplier, the employer's experience modification factor, schedule credits, and minimum premium. The state-by-state table on this page shows illustrative filed base-rate estimates for 5191 so an office-machine or IT-hardware service company can compare the spread, but the figure is a benchmark, not a binding quote. 5191 is a service-and-repair classification in hazard group E, lighter than electrical-construction trades but carrying travel and equipment-handling exposure.
How is 5191 different from clerical code 8810?
5191 covers the field technicians who physically install, service, and repair office machines and computer hardware at customer sites. Code 8810 Clerical Office Employees covers the office staff who handle scheduling, dispatch, billing, and administrative duties from a desk. Whether a 5191 employer's clerical staff can be separately rated to 8810 — rather than absorbed into the field payroll — depends on the standard-exception rules of the governing state bureau, so confirm the state's treatment before splitting payroll at audit.
