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 staying off your own policy means
In Arizona the default runs the other way from what many owners expect. A sole proprietor, and an LLC member who owns 50% or more, is not covered by the business’s workers compensation policy unless they elect coverage in writing. Members who own less than 50% and work in the business are treated as employees and must be covered. Staying outside the policy keeps premium down, and for an owner with employees who personally stays off job sites it can be reasonable. But it means your own injury brings no benefits from the policy you’re paying for, so owners who do physical work should think carefully before leaving themselves off.
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.
