Arizona business insurance requirements

Arizona requires workers' compensation from the first employee, part-timers and seasonal help included. It has no state disability or paid family leave program, though employers must provide earned paid sick time. On the liability side, Arizona's constitution bars the legislature from capping damages for injury or death, and fault is split under pure comparative negligence with mostly several liability.

Workers' compensation requirements

Under A.R.S. 23-902, every person "who employs any workers or operatives regularly employed in the same business" is subject to the Act, and "regularly employed" includes work that runs only part of the year. Domestic servants are the only excluded class. The Industrial Commission of Arizona (ICA) puts it plainly: a business with even one full- or part-time worker generally must carry coverage, and a corporation's covered employees can include its officers, directors and shareholders. The employer pays the whole premium; deducting any part from wages is prohibited.

Owners are handled one entity type at a time (A.R.S. 23-901). Sole proprietors and working partners are covered only if the carrier accepts their application by endorsement. A working LLC member who owns less than 50% is an employee; one who owns 50% or more can elect in. A sole proprietor who does contract work can sign a waiver with the hiring business's carrier so that business owes no premium on them (A.R.S. 23-961(N)). Read can owners and officers exclude themselves from workers' comp? before relying on any of these.

A.R.S. 23-907 makes going bare expensive. An uninsured employer loses the defenses of assumption of risk and contributory negligence, and proof of injury is prima facie evidence of its negligence. If the injured worker claims through the ICA instead, the state's Special Fund pays and bills the employer for those benefits plus a penalty of 10% or $1,000, whichever is greater, which becomes a judgment and an eight-year lien on its property.

Two Arizona quirks catch out-of-state owners. First, employees may reject the comp system in writing before an injury and keep the right to sue (A.R.S. 23-906); it is rare, and the employer must forward the notice to its carrier within five days. Second, a written independent contractor agreement meeting the eight conditions in 23-902(D) creates a rebuttable presumption of contractor status, and if it is given to the carrier, no premium may be charged on those payments. That is a premium audit point worth knowing; see independent contractors and workers' comp: the misclassification risk and premium audits: how they work and how to prepare.

Arizona has no state fund. The State Compensation Fund, founded in 1925, now operates as CopperPoint, a mutual holding company. Employers declined by the voluntary market use the Assigned Risk Plan; see assigned risk and residual markets for workers' comp. NCCI files full rates here rather than loss costs: it proposed a 6.7% voluntary rate decrease for January 1, 2026, and in a July 28, 2026 filing, a further 0.2% decrease for January 1, 2027 (NCCI). Workplace safety is enforced by ADOSH, Arizona's own OSHA state plan within the ICA (OSHA).

Disability and paid leave mandates

Arizona has no state temporary disability insurance and no paid family and medical leave program in 2026. It does require earned paid sick time (A.R.S. 23-372): one hour per 30 hours worked, with use capped at 40 hours a year at employers with 15 or more employees and 24 hours at smaller ones, unless the employer sets a higher limit. Longer absences are covered only by voluntary benefits such as group short- and long-term disability insurance for employers; compare other states in state disability and paid family leave programs: every mandate in 2026.

Commercial auto requirements

For policies issued or renewed since July 1, 2020, the minimum liability limits are $25,000 per person and $50,000 per accident for bodily injury and $15,000 for property damage (A.R.S. 28-4009). On a fleet policy covering seven or more vehicles, the per-accident limit does not stack by vehicle. Interstate for-hire carriers of general freight need $750,000 under federal rules, more for hazardous materials; see FMCSA insurance requirements and filings for motor carriers and commercial auto insurance: what it covers and what it leaves out.

The business insurance market in Arizona

Wildfire is the dominant catastrophe peril. FEMA's declarations data show 41 federal declarations for Arizona from January 2016 through early October 2026, and 29 of them were wildfire declarations, mostly fire management assistance grants (OpenFEMA). Property underwriters look closely at defensible space and wildland-urban interface scores; see wildfire and commercial property insurance: cover, cost and mitigation. Most of the rest are severe storm and flood declarations.

Surplus lines brokers remit a 3% tax on gross premiums for Arizona-home-state insureds (A.R.S. 20-416), plus a stamping fee charged by the brokers' association that the Department contracts with (A.R.S. 20-167). Ask your broker for the current fee; surplus lines taxes, stamping fees and diligent search explains how both appear on an invoice.

Liability law that affects premiums

Arizona applies pure comparative negligence: a plaintiff's fault reduces damages but never bars the claim (A.R.S. 12-2505). Liability is several only, so each defendant pays its own percentage of fault, and juries can assign fault to nonparties (A.R.S. 12-2506). The exceptions are narrow: a party still answers for another's share when the two acted in concert to commit an intentional tort, or when the other person was its agent or servant. That second exception is why employers remain on the hook for employees' fault.

The bigger pricing factor is the constitution. Article 2, section 31 says no law may limit "the amount of damages to be recovered for causing the death or injury of any person," and article 18, section 6 adds that the amount recovered "shall not be subject to any statutory limitation" (Ariz. Const.). Arizona cannot enact the noneconomic caps common elsewhere, which is one reason buyers here should test their umbrella limits; see tort reform and liability insurance: what changes for business buyers and commercial umbrella insurance.

Contractors should know A.R.S. 32-1159: a private construction contract clause that indemnifies a party for its own sole negligence is void. Deadlines run two years for personal injury and property damage (A.R.S. 12-542) and six years for debts on written contracts executed in Arizona (A.R.S. 12-548).

• Industrial Commission of Arizona (azica.gov): Claims Division and Insurance Section 602-542-4661. The ICA's online lookup shows an employer's current comp carrier, and it takes reports of uninsured employers through its complaint hotline.
• ADOSH for workplace safety and inspections, part of the ICA.
