Idaho Workers' Compensation Requirements: What Employers Must Know

Coverage Basics in Idaho

Idaho requires most private employers with five or more employees to carry workers' compensation insurance. The state mandates coverage for any injury or illness that occurs in the course of employment, regardless of fault. Employers may choose a licensed insurer or self‑insure if they meet the state's minimum financial requirements.

Premium Calculation and Payment

Premiums are based on payroll totals and a classification factor that reflects job risk. Employers file quarterly wage statements with the Idaho Workers' Compensation Board (WCB). Premiums are paid monthly or quarterly, depending on the chosen payment schedule, and late payments incur penalties.

Reporting Obligations and Deadlines

Injuries must be reported to the insurer within 30 days of the incident. Employers must also file a Form W-5, Workers' Compensation Claim, with the WCB within 30 days of the injury. Failure to report promptly can result in denial of benefits and potential fines.

Employee Benefits Overview

Employees injured on the job can receive medical treatment, temporary total disability (TTD) payments, permanent partial disability (PPD) benefits, and, in rare cases, permanent total disability (PTD). Benefits are capped by the state's benefit tables, and the employer's insurance policy may include additional coverage limits.

Claims Process and Dispute Resolution

Once an injury is reported, the insurer evaluates the claim and may request medical exams. If a dispute arises, the employee can file an appeal with the WCB, which may conduct a hearing. Employers should keep detailed records of all incidents and medical reports to support the claim.

Common Compliance Mistakes to Avoid

• Ignoring the 30‑day reporting window.
• Failing to keep accurate payroll records for classification calculations.
• Not updating employee status changes (hires, terminations) promptly.
• Using an unlicensed insurer.
• Overlooking the requirement to provide a copy of the workers' compensation policy to employees.
