Arizona treats working owners differently according to their business form and ownership share. There is no blanket exemption for every owner or independent contractor. Under A.R.S. § 23-901, a working LLC member with less than 50% ownership is included in the employee definition. A member with at least 50% is not included by that specific clause, but may be treated as an employee entitled to coverage if the member submits a written acceptance and the insurer approves it by endorsement. That statutory option describes electing coverage; it should not be mistaken for a general exemption filing. Sole proprietors and partners follow different rules.

Confirm the entity and percentage first

Gather formation documents, the current operating agreement or stock records, ownership percentages, and a description of the person’s work. Reconcile ownership as of the date being reviewed; a title such as “founder” or “managing member” does not prove a 50% interest. Identify the entity that employs the workforce and the policy that covers it. If ownership is split, recently transferred, or held through another entity, ask the carrier or qualified counsel to review the actual structure.

Verify the actual policy record

Do not treat an online owner declaration, customer waiver, or certificate as final proof of whether the owner is insured. If a qualifying member elects coverage, retain the written application and insurer endorsement naming the person and effective date. If the owner is not included, confirm that result against the statute, policy, and carrier records; keep employee coverage separate. Arizona’s Industrial Commission provides employer coverage information and directs businesses to verify coverage through the applicable records.

Maintain the file as facts change

Keep ownership documents, any coverage election, insurer acknowledgment, policy declarations, and current coverage verification together. Recheck whenever membership interests transfer, the entity changes, or the person’s work changes. The statute and carrier policy control; unusual structures should be reviewed before relying on an owner’s coverage status.

The article says the form does not eliminate classification review. Match it to the person, insured employer, and working arrangement; separately check whether the proprietor has employees.
