Employer of record in Arizona: PEO rules, payroll accounts and what the client still owns (2026)

Arizona does not license or register PEOs or "employers of record" as of October 2026: the professional employer organization article of the Arizona Revised Statutes, A.R.S. 23-561 to 23-574, contains no registration section. What it does is set the rules of the relationship. A PEO located in Arizona must keep $100,000 in net worth or security, the agreement must say who buys workers' compensation, and the PEO reports unemployment contributions under its own account. The point that matters most for an EOR arrangement is A.R.S. 23-614: if the provider is neither a PEO nor a temporary services employer as the statute defines them, the client is the employer for unemployment insurance and the provider only pays wages as its agent.

This page is for a company outside Arizona, or a staffing firm, deciding whether to employ someone in Arizona through an employer of record (EOR) or PEO, or to register itself. How an EOR, a PEO, a staffing agency and payrolling differ is in what is an employer of record and payrolling services explained; the full Arizona checklist, including the joint JT-1 registration and E-Verify, is in hiring employees in Arizona; and the 2017 repeal of employment agent licensing is in staffing agency license in Arizona. This page adds the PEO article, the employer tests and what stays with you.

Arizona employer of record and PEO rules at a glance

Does Arizona license or register employer of record companies or PEOs?

No. The Legislature's Title 23 index lists the "Professional Employer Organizations" article as sections 23-561, 23-562 and 23-569 through 23-574, covering definitions, agreements, financial capability, liability, taxes, insurance, rights and licensing of covered employees. None of them requires a PEO to register with or be licensed by any agency, and we found no other Arizona statute that does as of October 2026. The term "employer of record" does not appear in the article.

The definitions in A.R.S. 23-561 still matter. A PEO is anyone "engaged in the business of providing professional employer services," whatever it calls itself, and those services are a co-employment relationship "in which all or a majority of the employees who provide services to a client or to a division or work unit of the client are covered employees." The relationship must be "intended to be an ongoing relationship and not a temporary or project-specific relationship," and a covered employee is one who "has executed a written notice of the co-employment relationship." The definition excludes a person "who hires temporary help for the purpose of supporting or supplementing a client's employees" and companies sharing staff within a commonly owned group.

The one financial rule is in A.R.S. 23-569: every PEO "located in this state" keeps "a minimum net worth of at least $100,000" or a bond, irrevocable letter of credit or securities worth $100,000, securing taxes, wages, benefits and amounts the Industrial Commission's special fund pays out if the PEO fails to pay. Because there is no registry, no agency checks this for you; ask for the audited statement or the bond.

Who is the employer for Arizona unemployment insurance?

A.R.S. 23-614 answers it directly, and the answer turns on what the provider is:

• A PEO or a temporary services employer. One "that contracts to supply a worker to perform services for a customer or client is the employer of the worker." A PEO "shall report and pay all required contributions to the unemployment compensation fund using the state employer account number and the contribution rate of the professional employer organization" (§ 23-614(G)).
• Anyone else. "A customer or client who contracts with an individual or entity that is not a professional employer organization or a temporary services employer to engage a worker to perform services is the employer of the worker," and the provider that pays the worker "acts as the agent of the employer for purposes of payment of remuneration" (§ 23-614(E)).

A temporary services employer has its own test in § 23-614(I): it supplies workers "in more than one industry" and does all of the following: negotiates the terms with clients, decides assignments, can reassign a worker a client rejects, sets pay, pays from its own accounts and keeps the right to hire and terminate. So an EOR that employs one Arizona worker for you is the employer for unemployment insurance only if it fits one of those two definitions. If it does not, the Department of Economic Security account the wages belong on is yours.

When a PEO agreement ends, or the PEO fails to file reports or pay, a client that was under the agreement for at least two years, or is not otherwise eligible for an experience rating, is treated as "a new employer without a previous experience record" (§ 23-614(H)).

Who carries workers' compensation in Arizona?

The agreement decides who buys the policy, and the statute makes both parties the employer. A professional employer agreement must "Specify whether the client or the professional employer organization will purchase and maintain the workers' compensation policy for covered employees from a carrier that is licensed to conduct business in this state," and a PEO that buys it must keep the loss records and give them to the client on request when the agreement ends (A.R.S. 23-562(A)(5)).

Under A.R.S. 23-901.08, while the agreement is in force the PEO "shall be regarded as a co-employer," and "The professional employer organization and its client shall be considered the employer for the purpose of coverage" and "both ... shall be entitled to protection of the exclusive remedy." When it signs a client, the PEO notifies its carrier and the Industrial Commission on a commission-approved form, stating whether "all or a majority of the client employer's workforce" is covered and, if not all, naming the client's own carrier. It must also tell the client in writing that the client must insure "any employees who are not covered by the professional employer agreement, even if such employees are hired after the execution" of the agreement. On termination, the PEO notifies the carrier and the Commission immediately.

Arizona's coverage requirement, A.R.S. 23-902, reaches every employer with workers "regularly employed" in the business, as our Arizona hiring checklist explains.

Which Arizona registrations, reports and notices still apply?

• Withholding and unemployment accounts. The Department of Revenue says that "To register for both an income tax withholding account with the Department of Revenue and an unemployment insurance account with the Department of Economic Security, the employer will need to complete the JT-1 application on AZTaxes" (ADOR). A PEO agreement must require the PEO to withhold and remit payroll and unemployment taxes (§ 23-562(A)(3)), but A.R.S. 23-571 says the article "does not relieve a client from paying any tax liability" under Arizona's tax titles.
• Form A-4. Each new employee completes it within five days of employment, or the employer withholds at the default rate; see the Arizona hiring checklist.
• E-Verify. A.R.S. 23-214 says "every employer, after hiring an employee, shall verify the employment eligibility of the employee through the e-verify program" and keep the record for the employment or three years, whichever is longer. With two co-employers, name the one that runs the check and keeps the record; see E-Verify requirements in Arizona.
• New-hire report. Within 20 days under A.R.S. 23-722.01; agree which party files.
• Notices. The PEO's notice of co-employment to each covered employee (§ 23-562(D)), and the written earned paid sick time notice "at the commencement of employment" under A.R.S. 23-375.
• Paid leave programs. Arizona has earned paid sick time but, as far as we found, no state paid family leave or disability insurance program that needs a separate employer registration.

What does the client company still own in Arizona?

By default, most of the employer role. Unless the agreement or the article says otherwise, "The client shall perform all responsibilities that otherwise apply to an employer in an employment relationship," while the PEO performs "only the responsibilities that are specifically required" (§ 23-562(C)). Under A.R.S. 23-570, the client is "solely responsible" for the quality and safety of its goods or services, for "Directing, supervising, training and controlling the work of covered employees," and for their acts while it does so, and under A.R.S. 23-573 any right an employee has under Arizona law that the agreement does not give to the PEO "shall remain enforceable against the client." In practice:

• Hiring and screening. We found no Arizona statute requiring pay ranges in postings or banning salary history questions, but a remote posting can pick up other states' rules (see pay transparency laws by state). Background checks follow Arizona background check laws, testing follows Arizona drug testing law, and a party may record an interview under Arizona's recording law.
• Non-competes. Arizona has no general statute and courts may blue-pencil; see Arizona non-compete law.
• Licensed staff. A covered employee who needs a state license is the client's employee for that license, and the client keeps control of licensed work (A.R.S. 23-574).
• Co-employment exposure. Wage and discrimination claims can name both parties; see joint employer liability for staffing agencies.
• Federal payroll taxes. The IRS says a client using a PEO "generally remains responsible" for employment taxes unless the PEO is IRS-certified; see the CPEO public listings.

When is registering your own company in Arizona the better route?

Arizona's own-employer setup is a single JT-1 for withholding and unemployment, workers' compensation, E-Verify, Form A-4, the new-hire report and the sick time notice. Registering yourself tends to win when you expect several Arizona hires, already run multi-state payroll, or the provider cannot show it is a PEO or temporary services employer under § 23-614, since then you may be the employer for unemployment insurance anyway. A PEO fits a company moving all or a majority of a team, division or work unit onto one provider for payroll, benefits and comp. A temporary services employer fits short assignments.
