If an Arizona business that is required to carry workers compensation goes without it, an injured worker can sue the owner directly and the employer loses key courtroom defenses, so the injury itself counts as evidence of negligence. On top of that, the state Special Fund can pay the worker and then bill the employer back for everything it spent, plus a penalty and interest, and the state can go to court to make the business stop operating until it gets covered.
Who this is for: Arizona owners weighing the real cost of skipping required coverage, or catching up after a lapse.
The short version
- You lose your legal protections. If a hurt worker sues, an uninsured employer can no longer argue the worker took on the risk or was partly at fault, and the injury itself counts as proof you were negligent (A.R.S. section 23-907).
- The worker chooses. A hurt worker can sue you at law or file a claim and be paid from the state Special Fund, which then comes after you.
- The state bills you back with a penalty. If the Special Fund pays, you owe what it spent plus a penalty of the greater of 10 percent or 1,000 dollars, plus interest, and it becomes a lien for eight years.
- Civil fines escalate. The commission can assess up to 1,000 dollars for a first violation, up to 5,000 dollars for a second, and up to 10,000 dollars for a third.
- It can go further. The state can get a court order to stop your business, and a knowing failure to insure can be charged as a class 6 felony.
What the penalties look like
Arizona stacks several consequences. The stripped defenses, the payback, the civil fines, and the criminal exposure can all attach to the same lapse.
| Consequence | Amount or effect | Source |
|---|---|---|
| Lost defenses in a lawsuit | No 'worker knew the risk' or 'worker was partly at fault' defense; the injury counts as evidence you were negligent. | A.R.S. section 23-907 |
| Special Fund payback | All benefits the fund paid, plus a penalty of the greater of 10 percent or 1,000 dollars, plus interest | A.R.S. section 23-907 |
| Lien on your property | The award acts as a judgment and a lien for eight years | A.R.S. section 23-907 |
| Escalating civil penalty | Up to 1,000 dollars, then up to 5,000 dollars, then up to 10,000 dollars for repeat violations | A.R.S. sections 23-907 and 23-961 |
| Order to stop operating | A court injunction to cease business until you secure coverage | A.R.S. section 23-907 |
| Criminal exposure | A knowing failure to insure can be charged as a class 6 felony | A.R.S. section 23-932 |
The full claim can land on you
The penalties are only part of it. If the Special Fund pays your injured worker, you have to reimburse the entire amount it spent, the medical care and the wage benefits, and then add the penalty and interest on top. That award becomes a judgment and a lien against your property for eight years. If instead the worker sues you directly, you defend that suit without the usual protections, because the law strips assumption of risk and contributory negligence and treats the injury as evidence of negligence. A single serious injury can dwarf years of premium either way.
How Arizona enforces it
Arizona's enforcement is different from a construction-site stop-work ticket some states hand out on the spot. Here, if the commission finds an employer operating uninsured, the state can seek a court injunction to make the business cease operating until it secures coverage, and it can assess escalating civil penalties that rise with repeat violations. A knowing or willful failure to secure required coverage can also be charged as a class 6 felony under the chapter's general penalty. For a sole proprietor or partner, the payback judgment and lien reach personal assets, so an owner cannot treat the business entity as a shield.
A Yuma example
Illustrative, not a quote. A Yuma roofing company with a five-person crew skips coverage to save money. A roofer falls and is badly hurt, and files a claim with the commission, which pays him from the Special Fund. The company is then billed back for everything the fund spent, plus a penalty of the greater of 10 percent or 1,000 dollars and interest, and that award becomes a lien on the owner's property for eight years. The company also faces a civil penalty and a possible order to stop work until it gets insured. A policy would have cost a fraction of that. See our workers comp for roofers page.
Real questions Arizona owners ask
What is the penalty for not having workers comp in Arizona?
An uninsured employer loses key legal defenses, can be billed back by the state Special Fund for what it paid plus a penalty of the greater of 10 percent or 1,000 dollars and interest, and can face escalating civil fines and a court order to stop work.
Can I be sued directly if I have no coverage in Arizona?
Yes. An injured worker can take an uninsured employer to court, and you can't argue the worker knew the risk or was partly to blame. The injury itself is treated as evidence you were at fault.
What happens if an employee is hurt and I have no coverage?
The worker can sue you or be paid from the state Special Fund. If the fund pays, you must reimburse the full amount plus a penalty and interest, and it becomes a lien on your property for eight years.
How large are Arizona's civil penalties for going uninsured?
They escalate with repeat violations: up to 1,000 dollars for a first violation, up to 5,000 dollars for a second, and up to 10,000 dollars for a third, on top of the Special Fund payback.
Can Arizona shut my business down for no coverage?
It can seek a court order to make the business cease operating until you secure coverage. This is an injunction through the courts, not an on-the-spot stop-work ticket like some states use.
Can not having workers comp be a crime in Arizona?
It can. A knowing or willful failure to secure required coverage can be charged as a class 6 felony under the chapter's general penalty statute, which is Arizona's lowest felony class.
How do I fix a coverage lapse?
Get a policy in force right away and talk with an agent about the gap. The sooner you are covered, the smaller the exposure, since the payback, penalties, and a direct lawsuit all grow the longer you go without.
Why Arizona owners choose Morrow
- We shop the right market for you. Arizona has no state fund, so you buy workers comp from private insurers on the open market, and we compare several to find your best rate. If your work is hard to place and no insurer will take you, a guaranteed state backstop (the NCCI-run assigned risk plan) will still cover you.
- We catch pricing mistakes. Your price depends heavily on the category your work falls into for pricing (the class code). Put people in the wrong category and you overpay for years. We review your payroll and classifications before you buy.
- Proof of coverage, fast. Need a certificate (proof of coverage) for a general contractor or a landlord before Monday? We turn those around the same business day for most carriers.
- We help lower the score that drives your price. Insurers give you a score based on your past claims that raises or lowers your cost (the experience modification rate). We review it each year, flag errors, and connect you with return-to-work and safety resources that bring it down.
- Real people when a claim happens. When someone gets hurt, we stay involved through the life of the claim, not just at renewal.
