Laws that shape business insurance in Idaho
- Noneconomic damages cap, Idaho Code 6-1603 ($509,013.28 from July 1, 2025, adjusted each July 1)
- Punitive damages cap of the greater of $250,000 or 3x compensatory, Idaho Code 6-1604
- Joint and several liability limited, Idaho Code 6-803
- Construction anti-indemnity for sole negligence, Idaho Code 29-114
- Contractor registration insurance requirements, Idaho Code 54-5210
Idaho requires workers' compensation from the first employee, whether that person is full-time, part-time, seasonal or occasional, and the policy has to be in force before the hire. Owners are the main exception: sole proprietors, partners, LLC members and 10% shareholder-officers are outside the law unless they elect in. There is no state disability or paid leave program, the auto minimum is 25/50/15, and Idaho caps noneconomic damages in injury suits, which keeps liability pricing calmer than in neighboring Washington or Oregon.
Workers' compensation requirements
Idaho Code 72-301 says "every employer" shall secure compensation, either with an authorized insurer or by qualifying as a self-insurer with the Industrial Commission. The Commission reads that literally: employers "with one or more full-time, part-time, seasonal, or occasional employees" must carry a policy, and coverage must be in place "before the first employee is hired" (employer FAQs). Waivers are prohibited, and premium may not be deducted from wages.
The exemptions sit in 72-212. Owners are exempt: a sole proprietor, a working member of a partnership or LLC, and a corporate officer who owns at least 10% of the voting stock and, if the corporation has directors, sits on the board. So are household domestic service, casual employment, outworkers, family members living with a sole proprietor (or with the owner of a single-member LLC taxed as one), associate real estate brokers and salespeople paid only by commission, volunteer ski patrollers and high school sports officials. Any exempt employer can elect coverage by written declaration with its insurer under 72-213. See can owners and officers exclude themselves from workers' comp? before you assume an exempt owner is uninsurable; most carriers will add one.
| Rule | Idaho |
|---|---|
| Who must carry it | Any employer with 1 or more employees, including part-time, seasonal and occasional |
| Owner exemptions | Sole proprietors, partners, LLC members, 10%+ shareholder-officers who are directors; each may elect coverage |
| Construction | No separate threshold; contractors answer for uninsured subs' workers (72-216) |
| Penalty | Misdemeanor; $2 per employee per day or $25 per day, whichever is greater, for up to 3 years (72-319) |
| State fund | Idaho State Insurance Fund, competing with private carriers |
Construction has no lower threshold because there is no threshold to lower. What contractors feel is 72-216: an employer is liable for comp to the employees of an uninsured contractor or subcontractor working under it, with a right to recover from that sub. Collect certificates and verify them with the Commission's coverage lookup; see managing subcontractor insurance and certificates. Contractor registration under Idaho Code 54-5210 also requires a comp certificate (or a statement of why none is needed) and general liability with products and completed operations of at least $300,000 single limit.
The penalties stack. Under 72-319, failing to insure is a misdemeanor, and an officer or LLC manager who had authority to buy coverage is personally liable for the benefits that accrue. The Commission can sue for the daily penalty for up to three consecutive years, add $500 for a second failure and $1,000 for a third within three years, and ask a court to shut the business down while the default lasts. The injured worker also gets an extra 10% of compensation plus attorney fees (72-210).
Idaho has four ways to buy. More than 300 private insurers are authorized; the Idaho State Insurance Fund, which has written comp since 1917, is a quasi-governmental insurer, not a state agency; employers turned down everywhere go to the assigned risk pool, administered by NCCI; and large employers can self-insure with Commission approval. NCCI files full rates here, not just loss costs. Its filing for January 1, 2026 proposed a 2.5% decrease for the voluntary market and a cut in the assigned risk surcharge from 50% to 45% (NCCI); ask your agent what the Department approved. One trap for out-of-state employers: a remote employee working from home in Idaho must be covered by a policy endorsed for Idaho, at any hours (Commission). See remote employees and workers' comp: coverage, claims and state rules and workers' compensation insurance: how it works.
Disability and paid leave mandates
Idaho has no state temporary disability insurance program and no state paid family or medical leave program as of 2026. Short-term disability is a voluntary benefit; see group short- and long-term disability insurance for employers. Federal FMLA applies at 50 employees. Employers with staff in mandate states should check state disability and paid family leave programs: every mandate in 2026.
Commercial auto requirements
Idaho's proof of financial responsibility is $25,000 per person and $50,000 per accident for bodily injury and $15,000 for property damage (Idaho Code 49-117(20)). The same floor applies to a contractor's pickup and a delivery van. $15,000 of property damage will not replace a late-model truck, let alone a storefront, so commercial accounts typically carry a $1 million combined single limit. For-hire carriers hauling general freight across state lines need at least $750,000 under 49 CFR 387.9; see FMCSA insurance requirements and filings for motor carriers and commercial auto insurance: what it covers and what it leaves out.
The business insurance market in Idaho
The comp market is unusually competitive for a small state, with the State Insurance Fund as a large domestic competitor rather than a last resort. Property exposures are wildfire and earthquake rather than wind. The magnitude 6.5 Stanley earthquake of March 31, 2020 (USGS) is a reminder that standard commercial property forms exclude earth movement; see earthquake insurance for businesses: coverage, deductibles, limits. Idaho has no FAIR plan or other property market of last resort; none appears among the plans in the Property Insurance Plans Service Office's member list (PIPSO), so hard-to-place property usually goes to the surplus lines market.
Surplus lines brokers pay a 1.5% tax on premiums, remitted by March 1 for the prior year, computed on the whole premium when Idaho is the insured's home state (Idaho Code 41-1229). A separate stamping fee is charged at a rate the Department's delegated contractor sets and the Department approves (IDAPA 18.06.06); the Surplus Line Association of Idaho's tax and fee estimator computes it at 0.5% of premium for 2025 and 2026 effective dates (SLA Idaho). See surplus lines taxes, stamping fees and diligent search.
Liability law that affects premiums
Idaho uses modified comparative fault with a 50% bar. A plaintiff recovers only if their negligence "was not as great as" that of the party being sued, and damages are reduced by the plaintiff's share (6-801). Each defendant is compared to the plaintiff individually, and joint and several liability survives only for parties acting in concert or as agents of one another (6-803).
Damages are capped. Noneconomic damages in personal injury and death cases started at $250,000 and adjust every July 1 with the state average wage (6-1603); the Commission's courtesy calculation puts the cap at $509,013.28 from July 1, 2025 (IIC). The cap does not apply to willful or reckless misconduct or to conduct that would be a felony. Punitive damages need clear and convincing proof, cannot be pleaded without the court's leave, and are capped at the greater of $250,000 or three times compensatory damages (6-1604). Construction contracts cannot make a sub indemnify the owner or GC for that party's sole negligence (29-114); see indemnification and hold harmless clauses and your insurance.
Filing deadlines: two years for personal injury and wrongful death (5-219), three years for trespass and injury to goods (5-218), and five years on a written contract (5-216).
