How to Form an LLC in Arizona: Complete 2026 Guide

Arizona offers one of the simplest and cheapest LLC formation processes in the country: $50 to the Arizona Corporation Commission (ACC), no annual report, and a flat 2.5% state income tax that's among the lowest in the nation. The combination of rock-bottom formation costs, zero annual report fees, and a growing economy (Phoenix is the 5th largest city in the U.S.) makes Arizona an increasingly popular state for LLC formation.

The thing you need to know: publication requirement. Arizona requires most new LLCs to publish a notice of formation in an approved local newspaper within 60 days of approval. However, if your statutory agent's address is in Maricopa or Pima County (covering Phoenix, Tucson, and surrounding areas), the ACC publishes it automatically in their online database at no extra charge. Outside those counties, publication costs $80–$120.

Arizona LLC at a Glance

What You Need Before Filing in Arizona

Arizona uses the Arizona Corporation Commission (ACC) — not the Secretary of State — for LLC filings. File online through eCorp (ecorp.azcc.gov). You need:

1. LLC name that includes "Limited Liability Company," "LLC," or "L.L.C." and is distinguishable from existing Arizona entities. Search the ACC Entity Search to check availability. Name reservation costs $10 and holds your name for 120 days.
2. Statutory agent (Arizona's term for registered agent) with a physical street address in Arizona (P.O. boxes not accepted). The agent must be an Arizona resident or a business entity authorized to do business in Arizona. You can serve as your own statutory agent if you have an Arizona street address.
3. Articles of Organization details: LLC name, statutory agent name and Arizona street address, management structure (member-managed or manager-managed), organizer name and address, and known place of business address.
4. Publication plan: If your statutory agent is outside Maricopa or Pima County, identify an ACC-approved newspaper in the county where your agent is located for the publication requirement.

Step-by-Step: Forming an Arizona LLC in 2026

Step 1: Choose and Verify Your LLC Name

Search the ACC Entity Search to confirm your name is available. Your name must include "Limited Liability Company," "LLC," or "L.L.C." and cannot be deceptively similar to an existing Arizona entity. Optional: reserve the name for 120 days for $10.

Step 2: Appoint a Statutory Agent

Every Arizona LLC must designate a statutory agent with a physical street address in Arizona. The agent receives legal documents and official correspondence on behalf of the LLC. Northwest Registered Agent charges $39 for LLC formation and includes a free year of statutory agent service in Arizona. Pro tip: If you use an agent in Maricopa or Pima County, you skip the newspaper publication requirement entirely.

Step 3: File the Articles of Organization

Submit the Articles of Organization through the ACC eCorp portal. The filing fee is $50. You'll need to specify the LLC name, statutory agent details, management structure (member-managed or manager-managed), organizer information, and known place of business. Payment by Visa or MasterCard. Standard online processing takes 7–10 business days; expedited processing ($85 total) takes 3–5 business days.

Step 4: Publish Notice of Formation

Within 60 days of your Articles being approved, you must publish a notice of formation. If your statutory agent is in Maricopa or Pima County: The ACC automatically publishes your notice in its Public Notice Database at no charge. If outside those counties: Publish in an ACC-approved newspaper in the county where your statutory agent is located for three consecutive publications. Cost: $80–$120. After publication, file an Affidavit of Publication with the ACC.

Step 5: Obtain Your EIN (Federal Tax ID)

Apply for an Employer Identification Number at IRS.gov. It's free and takes about 5 minutes online. Required for business banking, hiring employees, and filing taxes.

Step 6: Draft an Operating Agreement

Arizona does not require an operating agreement, and it's not filed with the state. However, it's critical for defining ownership percentages, profit distribution, management authority, and dissolution procedures. Without one, Arizona's default LLC statutes under Title 29 apply.

Step 7: Register for State and Local Taxes

Register with the Arizona Department of Revenue (AZTaxes.gov) for a Transaction Privilege Tax (TPT) license if you sell taxable goods or services. Arizona's TPT ranges from 5.6% to 11.2% depending on city and county. Many Arizona cities also require a local business license ($7–$100+).

Best Online Service for Arizona LLC Formation

We recommend Northwest Registered Agent for Arizona LLC formation based on three factors:

2. Publication waiver: Northwest uses a Maricopa County statutory agent address, which means the ACC publishes your notice automatically at no charge — saving you $80–$120.
3. Arizona expertise: They file through the ACC eCorp portal (not the Secretary of State, which is a common mistake) and handle the statutory agent designation correctly.

What's included in the $39 package: Articles of Organization preparation and filing, statutory agent service for 12 months, business address on public filings, online document dashboard, and lifetime customer support.

Arizona-Specific Considerations

The 2.5% Flat Tax: Among the Lowest in the Nation

Arizona's flat 2.5% income tax rate (2025) is one of the lowest among states that levy an income tax. A proposed reduction to 2.42% for 2026 (S.B. 1318) is under consideration. As a pass-through entity, your LLC's profits flow to your personal tax return and are taxed at this flat rate. There is no separate franchise tax or entity-level tax for standard LLCs.

What this means in practice: An Arizona LLC owner earning $100,000 in profit pays just $2,500 in state income tax. Compare that to California (up to 13.3% + $800 minimum franchise tax), New York (up to 10.9%), or even Colorado (4.4%).

No Annual Report: Arizona's Hidden Advantage

Arizona is one of the few states that does not require LLCs to file an annual report or pay any annual state fee. This makes Arizona's ongoing LLC maintenance cost effectively $0 per year in state fees. Most states charge $50–$200+ annually for this requirement.

However, you should still keep your statutory agent information and business address updated with the ACC. If changes occur, file a Statement of Change ($5 fee).

The Publication Requirement: What It Actually Costs

Arizona's publication requirement is often cited as a drawback, but in practice:

• Maricopa County agents (Phoenix metro): $0 — ACC publishes automatically
• Pima County agents (Tucson metro): $0 — ACC publishes automatically
• All other counties: $80–$120 for three newspaper publications

Since Maricopa and Pima counties cover the vast majority of Arizona's population and business activity, most LLC owners effectively pay nothing for publication. Using a formation service like Northwest with a Maricopa County agent address eliminates this cost entirely.

When Arizona Is NOT the Right Choice

Don't form in Arizona if:

• You don't live or do business in Arizona. The low tax rate only benefits Arizona residents. Forming in AZ while living elsewhere creates foreign registration requirements.
• You want zero state income tax. Texas, Florida, Wyoming, Nevada, and Washington have no personal income tax.
• You want maximum privacy. Arizona publishes member/manager names on the Articles of Organization. Wyoming and New Mexico offer stronger anonymity.

Arizona makes sense if: You live in Arizona, want rock-bottom formation costs ($50), zero annual fees, and one of the lowest state income tax rates in the country (2.5%).

Original Research: Arizona LLC Total Cost Analysis

We analyzed ACC data and fee schedules to calculate the true compliance cost for Arizona LLCs:

Finding: Arizona is one of the cheapest states in the country for LLC formation and maintenance. At $50 to form and $0/year to maintain, the 3-year total state cost is just $50 (DIY with self as agent). Only New Mexico ($50 filing, $0 annual) matches this. The 2.5% flat income tax is significantly lower than most states, making Arizona an excellent choice for residents who want minimal government overhead on their business.

Next Steps: Form Your Arizona LLC

If Arizona is the right fit:

1. Use an online formation service to file through the ACC eCorp portal correctly
2. Budget $89 for year one: $39 (Northwest) + $50 (state filing fee)
3. Choose a Maricopa/Pima County agent to skip the newspaper publication requirement
