In Idaho, whether you must cover family members depends on where they live and how your business is set up. Family members who dwell in your household are exempt when you run a sole proprietorship or a single-member LLC taxed as a sole proprietorship, with no filing needed. A relative who does not live in your household is exempt only if that family member files a written declaration of election for exemption with the Idaho Industrial Commission; otherwise a paid relative counts like any other employee.
Who this is for: Idaho owners of family businesses whose only or main workers are relatives, and who want to know when the coverage duty applies.
The short version
- Household family can be exempt automatically. Relatives who live in your home are exempt when you are a sole proprietor or a single-member LLC taxed as one, with no filing.
- Out-of-household family must file to be exempt. A relative who does not live with you is exempt only if they file a written declaration of election for exemption with the Industrial Commission.
- Otherwise, paid family count. A relative on the payroll who does not fit an exemption is an employee and triggers the coverage duty.
- Structure matters. The automatic household exemption is tied to a sole proprietorship or single-member LLC, not to every business type.
- Coverage still helps. Exempting family saves premium but leaves an injured relative to rely on their own health coverage.
How Idaho treats family workers
Idaho splits family into two situations. The first is a family member who dwells in the employer's household: when you run a sole proprietorship, or a single-member LLC that is taxed as a sole proprietorship, that live-in relative is exempt by default and no paperwork is required. The second is a family member who does not dwell in your household: that relative is not automatically exempt and is treated as an employee unless the family member files a written declaration of election for exemption with the Industrial Commission on the required form. The table shows the common cases.
| Family situation | Exempt from coverage? | What is needed |
|---|---|---|
| Relative who lives in your home, sole proprietorship | Yes | Automatic, no filing |
| Relative who lives in your home, single-member LLC taxed as a sole prop | Yes | Automatic, no filing |
| Relative who does not live with you | Only if they file | The family member files a written declaration of election for exemption |
| Relative who does not file and does not live with you | No | Treated as an employee; must be covered |
| Family member working in a corporation or multi-member LLC | Depends on owner rules | The household exemption is tied to a sole prop or single-member LLC |
When family coverage is still worth it
Being exempt is not the same as being protected. If a live-in relative is exempt and gets hurt on the job, there is no comp to pay the medical bill or replace lost wages, and their own health plan may deny a work injury. Many family businesses still put relatives on the policy for exactly that reason, and a general contractor or client that wants proof of coverage will not care that the worker is family. We can price the policy with and without eligible family included, so you can weigh the premium against the protection.
Where the exemption ends
The automatic household exemption is narrow. It depends on the relative living in your household and on your business being a sole proprietorship or a single-member LLC taxed as one. A cousin who lives across town, a relative who works for your corporation, or a family member in a multi-member LLC does not get the automatic pass; an out-of-household relative has to file the written declaration of election for exemption to be left out, and inside a corporation the owner rules control. When in doubt, treat a paid relative as an employee and cover them, then adjust if an exemption clearly applies.
A Rexburg example
Illustrative, not a quote. A Rexburg auto shop is a sole proprietorship, and the owner's son, who lives at home, works the counter. Because the son dwells in the household and the shop is a sole proprietorship, he is exempt with no filing. When the owner later hires a nephew who lives in his own apartment, that nephew is treated as an employee unless he files a written declaration of election for exemption, so the shop puts him on the policy.

Real questions Idaho owners ask
Do I need workers comp for family members in Idaho?
It depends on where they live and your business type. Relatives who live in your household are exempt when you are a sole proprietor or single-member LLC. A relative who lives elsewhere counts as an employee unless they file for exemption.
Are family members who live with me exempt in Idaho?
Generally yes, if you run a sole proprietorship or a single-member LLC taxed as a sole proprietorship. A relative who dwells in your household is exempt by default, with no filing required.
What about a relative who does not live with me?
That relative is not automatically exempt. They are treated as an employee and must be covered unless the family member files a written declaration of election for exemption with the Idaho Industrial Commission.
Does the family exemption apply to my corporation?
Not through the household rule. The automatic household exemption is tied to a sole proprietorship or single-member LLC. Inside a corporation, the officer and employee rules decide who must be covered.
My relative is exempt. Should I still cover them?
Often yes. An exempt relative who is hurt has no comp to pay medical bills or lost wages, and their health plan may deny a work injury. Many family businesses cover relatives anyway for that protection.
A client wants proof of coverage but I only employ family. What now?
You can buy a policy and include eligible family so you can show proof of coverage. The contract can require it even when the state exemption would otherwise let you skip coverage on relatives.
How does an out-of-household relative claim the exemption?
The family member files a written declaration of election for exemption with the Idaho Industrial Commission on the required form. Until that is filed, the relative is treated as a covered employee.
Why Idaho owners choose Morrow
- We shop the right market for you. In Idaho you can buy workers' comp from any of the hundreds of private insurers licensed here, or from the state-chartered Idaho State Insurance Fund, which competes right alongside them. That lets us shop your rate widely, and if your work is too risky for any of them, there's a state-backed fallback plan that still has to cover you.
- We catch pricing mistakes. Your price depends heavily on the category your work falls into for pricing (the class code). Put people in the wrong category and you overpay for years. We review your payroll and classifications before you buy.
- Proof of coverage, fast. Need a certificate (proof of coverage) for a general contractor or a landlord before Monday? We turn those around the same business day for most carriers.
- We help lower the score that drives your price. Insurers give you a score based on your past claims that raises or lowers your cost (the experience modification rate). We review it each year, flag errors, and connect you with return-to-work and safety resources that bring it down.
- Real people when a claim happens. When someone gets hurt, we stay involved through the life of the claim, not just at renewal.
