Workers’ Compensation Insurance Requirements in Idaho
Idaho’s Industrial Commission enforces workers’ comp coverage on every employer with even one employee, a rule that catches many small roofing, electrical, and plumbing outfits off guard when they hire their first helper. While Idaho’s rates sit close to the national median, contractors still face real financial exposure, including personal liability and daily civil penalties, if they operate without coverage. Understanding exactly who is exempt as an owner versus who counts as an employee is critical before you take on your first job.
Idaho Workers’ Compensation Legal Requirements
Idaho Code Title 72 requires coverage the moment an employer has one or more employees, full-time, part-time, or seasonal, and the Idaho Industrial Commission’s Employer Compliance Division enforces it.
- No minimum headcount exemption exists: coverage must be in place before the first employee begins work, per Idaho Code Section 72-301.
- Sole proprietors and LLC working members are exempt on themselves under Idaho Code Section 72-212, but corporate officers are not automatically exempt and must file a specific election to opt out.
- Uninsured employers face a civil penalty of $2 per employee per day (or $25/day, whichever is greater), personal liability for all benefits owed plus a 10% penalty, and possible misdemeanor charges.
- The Idaho Contractors Board and Industrial Commission coordinate, and proof of workers’ comp coverage or a valid exemption filing is commonly checked during contractor licensing compliance.
How Idaho’s Workers’ Comp System Works
System type: Private Carrier Market
Idaho is a competitive state where contractors can buy coverage from any licensed private carrier or from the Idaho State Insurance Fund (ISIF), a nonprofit competitive fund that isn’t a monopoly. In the 2024 Oregon DCBS rate study, Idaho ranked 25th of 51 states overall, with an index rate at 101% of the national median, putting it almost exactly in the middle of the pack nationally.
How Idaho’s Rates Compare by Trade
| Trade (NCCI Class Code) | National Rank (of 51) | Rate per $100 of Payroll |
|---|---|---|
| Roofing (Class 5551) | 43rd of 51 | $3.09 |
| Electrical Wiring (Class 5190) | 31st of 51 | $2.11 |
| Plumbing NOC (Class 5183) | 32nd of 51 | $2.52 |

Filing a Workers’ Comp Claim in Idaho
An injured worker or employer reports the injury to the Idaho Industrial Commission, and the insurance carrier is responsible for authorizing medical treatment and calculating wage-replacement benefits based on the employee’s average weekly wage. The Industrial Commission’s Employer Compliance Division actively investigates uninsured employers and misclassification, particularly on construction sites, so a claim filed against an uninsured roofing, electrical, or plumbing contractor can trigger a compliance investigation in addition to the injured worker’s benefits claim.
Penalties for Non-Compliance
Idaho penalizes uninsured employers with a civil fine of $2 per employee per day of noncompliance (or $25/day, whichever is greater), personal liability for all benefits plus a 10% penalty and attorney fees, and misdemeanor criminal exposure under Idaho Code Title 72.

How Much Does Workers’ Comp Insurance Cost in Idaho?
Idaho’s rates sit close to the national median across most trades, though roofing costs considerably more per $100 of payroll due to fall-risk exposure. Actual premiums vary by payroll, claims history, and experience modifier.
| Trade | Estimated Cost per $100 Payroll | What Drives It |
|---|---|---|
| Roofing | $3.09 (per the Oregon study’s Class 5551 rate) | Fall-risk exposure, though Idaho’s roofing rate ranks well below the national average |
| Electrical | $2.11 (per the Oregon study’s Class 5190 rate) | Moderate shock and fall hazards typical of residential and commercial wiring work |
| Plumbing | $2.52 (per the Oregon study’s Class 5183 rate) | Standard strain and laceration risk consistent with mid-market claims costs |
What Moves the Price Up or Down
- Idaho’s overall index rate ranked 25th of 51 states, right at 101% of the national median, so baseline costs are moderate
- Choosing between a private carrier and the Idaho State Insurance Fund can affect pricing and service, since both compete for your business
- Experience modifier and claims history directly affect the premium you pay above the base class rate
- Properly filing owner/officer exemption elections avoids paying for coverage you don’t legally need
