What Is an LLC in Arizona?
A limited liability company organized under the Arizona Limited Liability Company Act (A.R.S. § 29-3101 et seq.) is a flexible business entity that combines personal asset protection for its owners, known as members, with pass-through federal tax treatment and broad internal governance freedom. Members are generally shielded from personal liability for the company’s debts and obligations, with their exposure limited to what they have contributed to the LLC.
Arizona LLCs default to member-managed status, meaning all members share the authority to conduct the company’s day-to-day business, though the articles of organization may designate one or more managers under A.R.S. § 29-3407. For federal tax purposes, a single-member LLC is treated as a disregarded entity and a multi-member LLC as a partnership, unless the LLC elects corporate treatment by filing IRS Form 8832. Members may adopt an operating agreement to tailor the LLC’s governance, and A.R.S. § 29-3105 grants that agreement broad authority to override default statutory rules.
Arizona does not impose an entity-level franchise tax or annual report requirement on LLCs. However, newly formed LLCs must satisfy a publication requirement within 60 days of formation, and every LLC conducting taxable business activities must register for Arizona’s transaction privilege tax.
Arizona LLC Name Search
The name of every Arizona LLC must be distinguishable on the records of the Arizona Corporation Commission from the name of any other entity on file, as required by A.R.S. § 29-3112. The Commission compares the proposed name against all existing entities, reserved names, and registered trade names—deceptively similar names will be rejected. When evaluating distinguishability, the Commission disregards entity-type identifiers such as “LLC,” “Inc.,” or “Ltd.”
The name must contain one of the following designators: “limited liability company,” “limited company,” “L.L.C.,” “LLC,” “L.C.,” or “LC.” The statute prohibits an LLC name from including the words “association,” “corporation,” or “incorporated” or any abbreviation of those terms. The words “bank,” “deposit,” “credit union,” “trust,” or “trust company” may not appear in the name unless the LLC is actively and substantially engaged in that line of business.
Organizers can check availability through the Arizona Business Center Business Search before filing. Passing the search does not guarantee acceptance — the Commission makes the final determination when it reviews the articles of organization.
Name Reservation: A person may reserve an available name for 120 days by delivering an application to the Commission under A.R.S. § 29-3113. The reservation is transferable to another person by filing a signed notice of transfer.
Choosing an LLC Registered Agent in Arizona
Arizona requires every LLC to designate and continuously maintain a statutory agent in the state, the term Arizona uses in place of “registered agent.” The statutory agent receives service of process, legal notices, and official government correspondence on the LLC’s behalf, and must have a place of business or residence in Arizona under A.R.S. § 29-3115.
An eligible statutory agent must be one of the following:
- Individual: A resident of Arizona with a physical business or residential address in the state
- Domestic entity: An Arizona corporation or limited liability company
- Foreign entity: A foreign corporation or foreign LLC authorized to transact business in Arizona
The statutory agent’s street address is listed in the articles of organization and serves as the address where process may be personally delivered during normal business hours. A P.O. Box alone does not satisfy this requirement.
Arizona imposes an important consent safeguard: unless the statutory agent personally signed the articles of organization, the appointment does not take effect until the agent delivers a signed record to the Commission accepting the appointment. The Commission will not approve the formation filing until this acceptance is on record. If the LLC fails to maintain a statutory agent, it risks involuntary dissolution and may be unable to defend or initiate lawsuits in Arizona courts.
LLC Filing Requirements in Arizona
An LLC is formed in Arizona when the Arizona Corporation Commission accepts the articles of organization for filing, as provided in A.R.S. § 29-3201. One or more persons may act as organizers to deliver the formation document. The official form is Articles of Organization (Form L010), and instructions are available in the companion document (Form L010i) on the LLC Forms page. Every filing submitted to the Commission must be accompanied by a Cover Sheet.
The articles of organization must include the following:
- The LLC’s name, including an approved designator
- The company’s principal address
- The name, street, and mailing addresses in Arizona of the statutory agent
- Whether the LLC is member-managed or manager-managed
- If manager-managed, the name and address of each manager and each member holding a 20% or greater interest in capital or profits; if member-managed, the name and address of each member
The filing fee is $50 for standard processing, as listed on the Schedule of LLC Fees. The Commission accepts Visa and MasterCard for online and in-person payments and checks or money orders by mail. All filing fees are nonrefundable.
- Online: File through the Arizona Business Center, which requires creating an account. Online filings cost $85 (the $50 filing fee plus a $35 expedited-processing fee) and are typically processed faster than paper submissions.
- By Mail: Send the completed Form L010, Cover Sheet, statutory agent acceptance, and a check for $50 payable to “Arizona Corporation Commission” to 1300 W. Washington St., Phoenix, AZ 85007. Standard paper processing typically takes 14–21 business days.
- In Person: Deliver filings to the Phoenix office at 1300 W. Washington St., Phoenix, AZ 85007, or the Tucson office at 400 W. Congress St., Tucson, AZ 85701.
The Commission also offers accelerated services: next-day processing for $100, same-day processing for $200, and two-hour processing for $400, each in addition to the base filing fee. Accelerated filings may be submitted online, by fax, or by walk-in, not by mail.
Once the Commission files the articles, the LLC exists as a legal entity. The filing itself constitutes “conclusive proof that all conditions precedent that are required to be performed by the organizers have been satisfied,” as stated in A.R.S. § 29-3201(F).
Publication Requirement: Arizona requires a post-formation publication step. Within 60 days after the Commission files the articles, a notice containing the information from the articles must be published in a newspaper of general circulation in the county of the statutory agent’s street address for three consecutive publications. An affidavit of publication may then be filed with the Commission. However, LLCs whose statutory agent’s street address is in a county with a population exceeding 800,000 persons—currently, Maricopa County and Pima County are exempt from the newspaper publication requirement; the Commission satisfies this obligation by entering the information into its database under A.R.S. § 10-130.
Note: Arizona LLCs are not required to file annual reports with the Corporation Commission, making ongoing compliance simpler than in most states.

LLC Operating Agreement in Arizona
Arizona does not require an LLC to adopt an operating agreement, but A.R.S. § 29-3105 gives the agreement sweeping authority over the LLC’s internal affairs. The statute provides that the operating agreement governs “relations among the members as members and between the members and the limited liability company,” the rights and duties of any managers, and the LLC’s activities and affairs. In the event of a conflict between the operating agreement and the statute, “the provision of the operating agreement governs,” with limited exceptions. The operating agreement is not filed with the Corporation Commission—it is an internal document retained by the LLC.
An operating agreement matters because it replaces the statutory default rules with terms the members actually negotiate. Among the provisions it typically addresses are the allocation of profits and losses, capital contribution obligations, the process for admitting or removing members, restrictions on transfer of membership interests, the scope of managers’ authority, and procedures for dissolution.
Without an operating agreement, Arizona’s defaults apply. Management rests with all members on a majority-in-interest basis for ordinary-course matters and requires unanimous consent for extraordinary actions such as amending the operating agreement or issuing new transferable interests, under A.R.S. § 29-3407. Distributions before dissolution are made in equal shares among members under A.R.S. § 29-3404. A transfer of a membership interest does not give the transferee any right to participate in management, only the right to receive distributions — under A.R.S. § 29-3502.
A single-member LLC benefits from an operating agreement as well, because the document establishes a clear boundary between the member’s personal assets and the company’s assets, reinforcing the liability protection the LLC provides.
How to Get an EIN for an LLC in Arizona
A federal Employer Identification Number (EIN) is a nine-digit number assigned by the Internal Revenue Service to identify an LLC for tax reporting. An EIN is required for any LLC that will have employees, file excise or employment tax returns, or withhold taxes on payments to nonresident aliens. Single-member LLCs without employees are not strictly required to obtain one, but most Arizona banks require an EIN to open a business account, and an EIN is necessary to complete the Arizona Joint Tax Application.
The fastest method is the IRS EIN Online Application, which issues the number immediately upon completion. The applicant must have a valid Social Security Number or Individual Taxpayer Identification Number, and the LLC must be located in the United States. The online tool is available Monday through Friday, 7:00 a.m. to 10:00 p.m. Eastern Time.
Applicants who cannot use the online tool may complete IRS Form SS-4 and submit it by fax (approximately 4 business days) or by mail (approximately 4 to 5 weeks). The application requires the name and Taxpayer Identification Number of the LLC’s responsible party, the individual who owns, controls, or directs the LLC and its funds. For a single-member LLC, the responsible party is ordinarily the sole member.
Note: There is no fee to apply for an EIN. Be cautious of third-party websites that charge for a service the IRS provides at no cost.
Registering for State Taxes in Arizona
Arizona imposes a state income tax on individuals and corporations, but it does not levy an entity-level franchise tax or gross receipts tax on LLCs. Members of an LLC that is taxed as a pass-through entity report their distributive shares of income on their personal Arizona income tax returns. If the LLC elects to be taxed as a C corporation, the entity itself becomes subject to Arizona’s corporate income tax and must register with the Arizona Department of Revenue.
Arizona’s equivalent of a sales tax is the transaction privilege tax (TPT), which is levied on the vendor for the privilege of doing business in the state. Any LLC engaging in taxable business activities, such as retail sales, contracting, or providing certain services, must obtain a TPT license before conducting business. The Arizona Joint Tax Application (Form JT-1) is used to apply for the TPT license, employer income tax withholding, and unemployment insurance registration simultaneously. The application can be completed online at AZTaxes.gov, submitted by mail, or delivered in person to a Department of Revenue office.
| Tax Type | Agency | Registration Method | Fee |
| Transaction privilege tax (TPT) | Arizona Department of Revenue | AZTaxes.gov or Form JT-1 by mail/in person | $12 |
| Employer income tax withholding | Arizona Department of Revenue | Included in Form JT-1 | — |
| Unemployment insurance | Arizona Dept. of Economic Security | Included in Form JT-1 (DOR forwards to DES) | — |
Registering as an Employer in Arizona
An LLC that hires employees in Arizona must register for unemployment insurance, state income tax withholding, and workers’ compensation coverage. Arizona streamlines the first two obligations through a single application, the Arizona Joint Tax Application (Form JT-1), which the organizer files with the Department of Revenue. The Department of Revenue processes the employer withholding account and forwards the application to the Arizona Department of Economic Security (DES) to establish the unemployment insurance account. DES will mail a Determination of Unemployment Insurance Liability notice containing the LLC’s eight-digit UI employer account number and tax rate.
Workers’ Compensation Insurance: Arizona requires every employer with one or more employees to carry workers’ compensation coverage under the Workers’ Compensation Act. Arizona does not operate a state insurance fund; coverage must be obtained through a private insurance carrier. The Industrial Commission of Arizona oversees compliance and enforcement. Sole proprietors, partners, and LLC members with a minimum 10% ownership interest may be eligible to exclude themselves from coverage but must still insure all other employees.
New Hire Reporting: Federal and state law require employers to report all newly hired and rehired employees to the Arizona New Hire Reporting Center within 20 days of the hire date. The reporting program is administered through the Arizona Department of Economic Security.
The following table summarizes the employer registration requirements:
| Obligation | Agency | Registration Method |
| Unemployment insurance | Arizona Dept. of Economic Security (DES) | Form JT-1 via AZTaxes.gov (DOR forwards to DES) |
| State income tax withholding | Arizona Dept. of Revenue | Form JT-1 via AZTaxes.gov |
| Workers’ compensation | Private carrier (Industrial Commission of Arizona oversees) | Contact a licensed insurance carrier; ICA employer info |
| New hire reporting | Arizona Dept. of Economic Security | Arizona New Hire Reporting Center |
The LLC must also comply with federal employer obligations, including filing IRS Form 941 (Employer’s Quarterly Federal Tax Return), paying FUTA (Federal Unemployment Tax Act) taxes, and completing Form I-9 (Employment Eligibility Verification) for each new hire.
