How do you file a workers' comp claim in Phoenix?

  1. Tell your employer the same day if you can. Waiting can cost you your benefits.4 Put it in a text or email so there is a record.
  2. Get medical care and tell the doctor it happened at work.
  3. Fill out the Worker's Report of Injury, Form 407. A Spanish version is available from the Commission.5
  4. Send it to the Industrial Commission of Arizona. The Claims Division is at 800 W. Washington St., Phoenix 85007.2
  5. Do not email your Social Security number or other private details. The Commission asks you to fax them to (602) 542-3373 or send paper copies.6
  6. Keep a copy of everything, and write down the date you sent it.

The one-year clock starts when the injury shows up, or when you should reasonably know you have one.1 That matters for back injuries and other problems that build up slowly.

Does it cost money to file for workers' comp in Phoenix?

No. The Commission does not charge a fee to process a workplace injury claim, and it warns about scammers who ask for money to process one.3 Anyone charging you to "file your claim with the state" deserves suspicion. A lawyer who represents you is a different thing, so ask how any lawyer gets paid and get it in writing.

Can you sue your employer for a work injury in Phoenix?

Usually not. Workers' comp is usually your only claim against your employer or a coworker, unless their willful misconduct caused the injury.10 The trade-off is that the Commission describes the system as no-fault, so benefits are paid no matter who caused the job accident.11

There is one big exception. An employer who skips required workers' comp insurance loses that protection and can be sued in regular court.12 The Commission lists a Workers' Compensation Coverage Verification tool, so you can check whether your employer has coverage.13

What if someone outside your Phoenix job caused your injury?

Then you may have two claims. If another driver hit your work truck, or a contractor's scaffold fell on you, you can claim workers' comp and also bring a claim against that outside person.14 Phoenix is a busy place to drive for work. ADOT counted 10,449 injury crashes in the city in 2024, and those include plenty of people on the clock.15

Watch the one-year rule closely. If you do not sue that outside person within a year, your claim is treated as handed over to the workers' comp insurer.8 For a crash on a Phoenix street, the police report comes from Phoenix Police.16 On a freeway, ask DPS.17

What if you got sick from the heat on a Phoenix job?

Phoenix heat is a real danger. Maricopa County counted 233 heat-related deaths in 2025 with Phoenix as the injury city,18 and 74% of the county's heat deaths happened outdoors.19 Those numbers cover everyone, not only workers. If you got sick on a roof, a road crew or in a hot warehouse, treat it like any other injury. Report it to your employer the same day and ask a doctor to write down the cause.

What if a Phoenix worker died from a job injury?

Families use the Dependent Benefits Claim Form, Form 120, which the Commission provides.20 You can call the Phoenix office at (602) 542-4661 with questions.2 A death in a job accident can also go to the Medical Examiner, whose office is at 602-506-3322.21

When should you call a workers' comp lawyer in Phoenix?

  • Your claim was denied or your checks stopped.
  • The insurer's doctor says you are ready to go back and you are not.
  • Your employer says it has no insurance.
  • Someone outside your job caused the injury, because you have the one-year rule to watch.
  • You are told to sign a settlement and do not understand it.

Keep your records handy. Valleywise Health's records office is at (602) 344-5266, and it responds within 30 days.22
