Idaho law requires workers’ compensation insurance if you have one or more employees. No employees means no legal requirement. But that’s the simplified version, and contractors often face situations where the legal minimum doesn’t match what they actually need.

If you’re a sole proprietor working alone, Idaho doesn’t require you to carry workers’ comp on yourself. You can elect coverage voluntarily, but the state won’t penalize you for skipping it. The same applies to partners in a partnership and members of an LLC who actively work in the business. You can exempt yourselves from mandatory coverage.

The calculus changes the moment you hire anyone. One employee triggers the requirement. Part-time, full-time, seasonal. It doesn’t matter. And “employee” has a specific legal meaning that doesn’t always match how contractors think about their workforce. If you control how and when someone works, they’re probably an employee regardless of what your agreement calls them.

Subcontractor relationships get complicated. If you hire a sub who doesn’t have their own workers’ comp and they get hurt on your job, you could be on the hook. Idaho allows the Industrial Commission to hold the hiring contractor responsible for uninsured subs. General contractors know this, which is why most require proof of coverage before you step on their site.

That’s the practical reality that matters more than the legal minimum. You might not be required to carry workers’ comp as a solo operator, but good luck winning bids from general contractors who won’t take the risk. Many commercial clients expect it too. The cost of coverage becomes a cost of doing business if you want access to better-paying construction and trades work.

Coverage also protects you personally. Jobsite injuries without workers’ comp mean paying medical bills out of pocket or hoping your health insurance covers work-related incidents. Many policies don’t cover on-the-job injuries. One bad fall could wipe out a year’s profit.

For contractors in the Treasure Valley, the question isn’t really whether you need it legally. It’s whether you can afford the risks of not having it.
