This question has a short legal answer and a longer practical one. Legally: no, Arizona does not require workers compensation for a solo owner with no employees. Practically: a lot of solo owners end up buying it anyway, and the reasons are worth understanding before a contract forces a rushed decision.
Why solo owners end up carrying it
Contracts demand it. General contractors in particular often require every subcontractor on a job to carry workers comp, solo or not. Their motivation is direct: if you get hurt on their site without coverage, their policy may absorb the claim, and uninsured subs can show up as charges on their premium audit. Some accept Arizona’s sole proprietor waiver instead; many don’t. If GC work is part of your business, this question usually answers itself.
Your own injuries are the real exposure. Health insurance may cover treatment for a work injury (check your plan; some exclude work-related injuries), but it will not replace income while you can’t work. For a one-person business, the owner’s hands are the whole payroll. Workers comp with the owner included covers both treatment and partial wage replacement.
The math is sometimes closer than expected. A minimum-premium workers comp policy for a solo operation can cost less than people assume, especially in lower-risk classes. For trades, it costs more, but that tracks the actual risk of the work.
What excluding yourself means
Arizona lets sole proprietors, partners, and certain LLC members and officers exclude themselves from their own policy. Exclusion lowers premium, and for an owner with employees who personally stays off job sites, it can be reasonable. But excluded means excluded: your own injury brings no benefits from the policy you’re paying for. Owners who do physical work should think carefully before signing that election.
How this connects to the rest of your insurance
Workers comp handles employee injuries; general liability handles injuries to everyone else. Contracts usually ask for both, often alongside commercial auto.
