When coverage is required
Idaho generally requires coverage before you hire your first employee. Full-time, part-time, seasonal, and occasional workers all count unless the law exempts them. The Industrial Commission also says an out-of-state company with an employee working from home in Idaho needs a policy that covers Idaho. Count remote workers, not just people at your office or shop.
Owners, contractors, and exceptions
Idaho decides whether someone is an independent contractor by asking who controls the work. There is a limited family exception for certain relatives who live with the owner of a sole proprietorship or a single-member LLC taxed as one. It does not cover all relatives or all types of business. Get advice before you leave an owner, family member, or subcontractor off the policy.
If an employee is injured
Report every injury to your insurer quickly so a First Report of Injury can reach the Industrial Commission. The Commission says all injuries must be reported. Workers should tell you right away, because waiting can put their benefits at risk. If an employer refuses to report, the worker can contact the Commission for help starting a claim.
Operating without coverage
Running a business without coverage in Idaho is a crime (a misdemeanor). The Industrial Commission charges a penalty of $2 per employee per day or $25 per day, whichever is more. If a worker is hurt while you have no coverage, you can be personally responsible for all medical and lost-wage benefits. You will also owe a 10% penalty on those benefits and the worker's lawyer fees.
How to arrange coverage
Buy a policy from a licensed insurer or get approval to self-insure. You must pay the whole premium and cannot take any of it out of workers' pay. Before the policy starts, list every place people work in Idaho, including home offices, and any short jobs in other states. Keep proof that the policy covers Idaho with your records. A general certificate alone is not enough.
Benefits and return-to-work planning
A work injury can lead to medical care, time off work, a lasting disability, or benefits for family members if a worker dies. Who qualifies, waiting periods, how wages are figured, and benefit limits all depend on state law and the facts of the claim. Ask your insurer which benefits it is looking at and what records it needs. Go by the doctor's work limits, not your own guess about what the worker can do. If you can offer lighter work, describe the duties and hours clearly and plan it with the doctor and your insurer.
Preparing an accurate cost estimate
Gather payroll by job and location, a description of each type of work, details on working owners, subcontractor records, and your past claims. Ask the insurer to confirm your job classes, how the rate is figured, any experience modifier, the minimum premium, fees, and audit terms. This site's calculator uses a base rate that you enter. It does not give a state-approved rate or a real quote. Compare offers using the same numbers, and track staff and work changes during the year so the final audit is easier.
