With 190,000 small businesses operating across Idaho, the insurance market in ID is competitive but limited in carrier options. The Idaho Department of Insurance oversees all commercial insurance activity, and recent legislation (HB 312 (2025)) continues to shape requirements for contractors.

Idaho Insurance Requirements for Contractors
Workers' Compensation in Idaho
Idaho requires workers' compensation insurance for all businesses with 1 or more employees. The Idaho Department of Insurance enforces compliance, and penalties for operating without coverage include fines of up to $1,000 per day and potential criminal charges. For contractors with the inherent physical risks of the trade, WC is both a legal requirement and a business necessity.
General Liability Requirements
While Idaho doesn't set a state minimum for general liability coverage, the practical reality is different. Most commercial landlords in Boise and other ID metros require $1,000,000 in GL coverage before signing a lease. For contractors, clients will almost certainly require a Certificate of Insurance (COI) before awarding contracts.
