When coverage is required
Arizona generally requires workers' comp once you have employees, even just one. A small team or part-time schedule does not, by itself, make you exempt. Check the Industrial Commission's employer guidance before you decide a worker is not covered.
Owners, contractors, and exceptions
Working owners, corporate officers, and independent contractors each need their own review. A business name, tax form, or contract label is not enough to decide who is covered. Ask your insurer to list in writing who is included and who is left out, and what changes when you hire.
If an employee is injured
Workers should tell you right away. Your injury report is due within 10 days after you learn about the accident, sent through your insurer. A work death must be reported to the Industrial Commission by the next business day. The worker files their own claim separately, and your report does not replace it.
Operating without coverage
Arizona's Industrial Commission can fine an uninsured employer $1,000 to $10,000. It can also go to court to shut the business down until it gets coverage. A worker hurt while you are uninsured can sue you in court or file a claim with the Commission. A special state fund may pay the worker and then come after you for the money.
How to arrange coverage
Buy a policy from a licensed insurer, or apply to self-insure if you qualify. Ask your insurer how to report a claim before anyone gets hurt. Give supervisors a short checklist: get care, tell the insurer, use the state forms, and handle any separate safety reports. The workers' comp report does not cover every safety rule.
Benefits and return-to-work planning
A work injury can lead to medical care, time off work, a lasting disability, or benefits for family members if a worker dies. Who qualifies, waiting periods, how wages are figured, and benefit limits all depend on state law and the facts of the claim. Ask your insurer which benefits it is looking at and what records it needs. Go by the doctor's work limits, not your own guess about what the worker can do. If you can offer lighter work, describe the duties and hours clearly and plan it with the doctor and your insurer.
Preparing an accurate cost estimate
Gather payroll by job and location, a description of each type of work, details on working owners, subcontractor records, and your past claims. Ask the insurer to confirm your job classes, how the rate is figured, any experience modifier, the minimum premium, fees, and audit terms. This site's calculator uses a base rate that you enter. It does not give a state-approved rate or a real quote. Compare offers using the same numbers, and track staff and work changes during the year so the final audit is easier.
Forms, posters, and notices
These links go straight to Arizona’s official forms. Your insurer can often send a poster with your policy details already filled in.
Weekly benefit limits
These limits cap the wage replacement checks an injured worker can get. Medical care is paid separately. Limits change every year, so check the source for the latest figures.
Arizona pays wage benefits based on the worker's average monthly wage, up to a statutory maximum set each year. The Commission's page lists the maximum by date of injury.
Check a contractor’s coverage
The Commission explains how to look up an employer's coverage. It uses an NCCI web service that shows whether a policy was in force on a date, plus a list of approved self-insured employers.
Owner exemptions and elections
Arizona has a sole proprietor and independent contractor statement, and a separate form an employee can use to reject coverage before an injury. Owner choices are usually made through your insurance policy. Ask your insurer which owners are included or left out, and get the answer in writing.
Frequently asked questions
Is workers' comp required in Arizona?
Generally yes. Arizona requires coverage for employers with one or more employees, including part-time workers, unless a specific exclusion applies.
Do business owners need workers' comp in Arizona?
Working owners, officers, and independent contractors need a separate review. Ask the insurer to list who is included and excluded in writing instead of relying on titles or tax forms.
How long does an employee have to report a work injury in Arizona?
Employees should tell the employer right away. The employer reports the injury to its insurer within ten days of notice, and a work-related death must be reported to the Industrial Commission by the next business day. The worker's own claim is a separate filing.
What happens if a Arizona business doesn't have workers' comp?
The Industrial Commission can impose civil penalties of $1,000 to $10,000 and seek an injunction that stops the business until it complies. Injured workers can also sue an uninsured employer.
How do I get workers' comp insurance in Arizona?
Buy a policy from a licensed insurer through an agent, or apply to self-insure if the business qualifies.
How much does workers' comp cost in Arizona?
Cost depends mostly on your job class codes, the payroll in each class, your experience modifier, and the insurer's rates and minimum premium. Ask a licensed insurer or agent for the base rate for your class code in Arizona, then use this site's calculator for a rough estimate. Your final premium is set at the yearly audit.
