Do sole proprietors need workers compensation?

Check the state laws in where the sole proprietor is being operated. It changes from state to state. For example in California requires workers' compensation if there is one employee. But if it is a sole owner with no employees then the insurance is optional. In Alabama and Florida if you have four employees including the owner, then workers' compensation is a must. In Texas workers' compensation is not required at all, but the state does require the employer to post a sign stating that workers' compensation will not be provided.
