Arizona is one of a handful of states that still makes new LLCs publish a formation notice in a newspaper. Most guides stop there and leave founders assuming a $100+ newspaper bill is unavoidable. It isn't. If your statutory agent's address sits in Maricopa or Pima county, Arizona's own online public notice database handles the requirement for free, no newspaper involved.
That single fact changes how a founder should pick a registered agent in Arizona, and it's why this state gets its own dedicated walkthrough below, not just a footnote.
TL;DR
- Cheap to maintain: Arizona charges a flat $50 filing fee, skips the annual report most states require, and taxes pass-through income at a flat 2.5% rate.
- Step 1, name: reserve your LLC name through Form L001 for $10, or $45 expedited, good for 120 days and not renewable.
- Step 2, statutory agent: Arizona calls this role a "statutory agent," and it needs a physical in-state street address, no PO box.
- Step 3, Articles of Organization: file with the Arizona Corporation Commission, not the Secretary of State, now through the new Arizona Business Center portal.
- Step 4, publication: most LLCs must publish a formation notice in an approved newspaper for 3 consecutive runs within 60 days, unless the statutory agent is based in Maricopa or Pima county.
- Step 5, EIN without an SSN: founders without an SSN or ITIN apply by phone, fax, or mail using Form SS-4 instead of the online tool.
- Step 6, Form 5472: a 25%+ foreign-owned single-member LLC must file this annually, even at zero revenue, or risk a $25,000 minimum penalty.
- Ongoing compliance: no annual report, but a new 2026 policy checks dormant LLCs each January and requires a free existence confirmation within 60 days if flagged.
Why Form Your LLC in Arizona?
Arizona is one of the cheapest states to maintain an LLC in over the long run. The formation fee is a flat $50, there's no recurring annual report fee, and pass-through income is taxed at a flat 2.5% rate.
That combination matters more after year one than at formation. Many states charge a $50 filing fee up front, then quietly add a $100 to $300 annual report requirement every year after. Arizona skips that recurring cost entirely.
The trade-off is the newspaper publication requirement covered in Step 4, which some founders never hit if they pick the right statutory agent location. For a founder weighing states purely on long-term maintenance cost, Arizona's math is genuinely favorable, publication workaround included.
Step 1: Choose and Reserve Your LLC Name
Your LLC name needs to be distinguishable from existing Arizona entities and include a designator like "LLC" or "Limited Liability Company."
- Search first. The Arizona Corporation Commission's entity search lets you check name availability before filing anything.
- Reserve with Form L001. Filing this form holds your name for $10 standard processing or $45 for expedited handling.
- 120 days, no renewal. The reservation isn't renewable, so file your Articles of Organization before it lapses if the name matters to you.
Skipping reservation and filing your Articles directly is fine too. Reservation only matters if you need time between naming and filing.
Step 2: Appoint a Statutory Agent
Arizona statute uses the term "statutory agent" rather than "registered agent," though the industry uses both interchangeably. The role itself is the same: a person or company at a physical Arizona street address, available to receive legal notices and state correspondence for your LLC.
- No PO boxes. The address must be a real Arizona street address.
- Must stay continuously maintained. A lapsed statutory agent can trigger administrative dissolution of your LLC.
- The address matters beyond compliance. As covered in Step 4, where your statutory agent is physically located determines whether you owe a newspaper publication fee at all.
Most founders forming from outside Arizona use a commercial statutory agent service. Which county that service operates from is worth checking before you sign up, not after.
Step 3: File Your Articles of Organization
Your Articles of Organization is the document that legally creates your LLC. In Arizona, it's filed with the Arizona Corporation Commission (ACC), not the Secretary of State, a distinction that trips up founders used to how most other states run this process.
| Detail | What to expect |
|---|---|
| Filing agency | Arizona Corporation Commission, through the new Arizona Business Center portal, which replaced the older eCorp system starting January 12, 2026 |
| Filing fee | $50 flat, whether you file online or on paper |
| Processing time | Generally reported at around 2 to 3 weeks, though timing varies and is worth confirming directly with the ACC |
| Expedited option | An additional $35 typically brings turnaround to roughly 3 to 5 business days, for a total of $85. Confirm current expedite pricing with the ACC before filing |
Once the ACC approves your Articles, your LLC legally exists, and the 60-day publication clock covered next starts running immediately.
Step 4: Handle Arizona's Publication Requirement
Arizona requires most new LLCs to publish a Notice of LLC Formation in an ACC-approved newspaper for 3 consecutive publications, completed within 60 days of Articles approval. This is the step that catches founders who assumed formation ended at the ACC filing.
The Maricopa/Pima exemption is the practical lever here. If your statutory agent's address is in Maricopa county (Phoenix) or Pima county (Tucson), you don't need a newspaper at all. The ACC publishes your formation notice free of charge in its own online Public Notice database instead, satisfying the requirement automatically.
This isn't a loophole, it's a standing carve-out under the Arizona LLC Act. Most commercial statutory agent services are already based in Phoenix or Tucson by default, which means many founders clear this requirement for free without doing anything extra, as long as they confirm their agent's county before signing up.
What it costs outside Maricopa and Pima: for any other county, you'll need to publish in a newspaper the ACC approves for legal notices in that county. Pricing isn't centrally set, so costs vary by publication and column-inch rate.
- Reported range: roughly $30 to $300 or more, depending on the newspaper.
- Commonly cited practical range: about $80 to $120 for a typical filing.
- Get real quotes. Call 2 to 3 ACC-approved newspapers in your county directly, since prices aren't published in a single centralized list.
The takeaway: choosing a Phoenix or Tucson-based statutory agent service isn't just a location detail, it's a real cost and hassle avoidance decision worth making before you file, not after.
Step 5: Get an EIN, Even Without an SSN
An Employer Identification Number (EIN) is what the IRS uses to identify your LLC for tax purposes, and you'll need one to open a US bank account or file taxes. It's free directly from the IRS.
Founders with a Social Security Number or ITIN can typically get one online in minutes. Founders without either can't use that option and apply instead using Form SS-4 by phone, fax, or mail.
| Method | Who can use it | Typical speed |
|---|---|---|
| Online EIN application | SSN or ITIN holders | Minutes |
| Form SS-4 (phone, fax, or mail) | Founders without an SSN or ITIN | Same-day to several weeks |
The manual route's timeline mostly depends on IRS volume and whether the form was filled out completely the first time. A rejected submission means starting the wait over, so getting the responsible-party details right matters more here than in the online flow.
Step 6: File Form 5472 if the LLC Is Foreign-Owned
If your single-member LLC is 25% or more foreign-owned, the IRS requires an annual Form 5472 filing, even at zero revenue. This is a federal requirement, not an Arizona-specific one, but it applies regardless of which state you form in.
- Filed alongside a pro forma Form 1120, a placeholder corporate return required even though the LLC itself owes no separate corporate tax.
- Reports transactions between the LLC and its foreign owner, such as capital contributions or payments for services.
- Due on the same schedule as your income tax return, with extensions typically available the same way.
- Applies even when dormant. A low-activity LLC that made no money still has to file.
The IRS's stated minimum penalty for a late or missing Form 5472 is $25,000 per form, per year. It doesn't waive this for founders who didn't know it existed, so treat it as non-negotiable from day one.
Step 7: Handle Arizona's Ongoing Compliance
Arizona doesn't require an annual report, which is confirmed true for 2026 and is a real point in Arizona's favor versus states that charge a recurring report fee every year.
- New in 2026, the attestation policy. Starting with the January 12, 2026 Arizona Business Center launch, the Corporations Division reviews records each January for LLCs that have filed nothing in 2 years. Flagged LLCs get an electronic notice and must confirm continued existence in the portal within 60 days.
- It's free and dormancy-triggered, not a scheduled annual filing. Most active LLCs will never see this notice.
- Ignoring it has real consequences. An unanswered notice moves the LLC to "pending inactive" status, and after 120 days it can lead to administrative dissolution.
- State income tax: Arizona taxes pass-through LLC income at a flat 2.5% individual rate for 2026, since the LLC itself isn't taxed separately. This generally applies to Arizona-source or US-sourced personal income; a non-US-resident founder with no US-sourced income typically owes no Arizona tax, though this is general information, not tax advice, and individual situations vary.
Draft an Operating Agreement
Arizona doesn't require an LLC to file an operating agreement with the ACC, but skipping one leaves your business governed entirely by the state's default LLC rules, which may not match how you actually intend to run things.
- It spells out ownership percentages, voting rights, and how profits and losses get allocated among members.
- It documents what happens if a member wants to leave, sell their stake, or if the LLC needs to dissolve, avoiding disputes that default state law doesn't address cleanly.
- Banks and other institutions sometimes ask to see it when you open a business account or apply for financing, even though it isn't filed publicly anywhere.
Even a single-member LLC benefits from putting one in writing. It reinforces that the business is a separate legal entity from its owner, which matters if your liability protection is ever challenged.
Open a US Business Bank Account
Keeping business funds separate from personal money is what actually preserves your LLC's liability protection, and a dedicated bank account is the simplest way to do that.
- Most banks ask for your EIN, Articles of Organization, and operating agreement to open a business account, so having those documents ready speeds up the process.
- Founders without a US address or SSN can find this step harder, since some banks require an in-person visit, though a growing number of banks and fintech platforms support remote account opening for foreign-owned LLCs.
- Mixing personal and business funds, sometimes called commingling, is one of the fastest ways to undermine the liability shield an LLC is supposed to provide.
Set this up before the business takes in any revenue or spends any money, rather than treating it as a step you'll get to later.
Common Mistakes to Avoid
- Missing the 60-day publication window: the clock starts at Articles approval, not whenever you get around to it, and missing it can put your LLC out of compliance.
- Picking a statutory agent outside Maricopa or Pima without checking first: founders who could have avoided the newspaper requirement entirely end up paying $80 to $120 or more simply because their agent's county wasn't a factor in the decision.
- Treating the EIN as the finish line: for a foreign-owned LLC, the EIN is closer to the starting gun on an annual Form 5472 obligation than the end of the process.
- Skipping Form 5472 because there's no revenue yet: the filing requirement doesn't care whether the LLC has made money.
- Ignoring the attestation notice if it arrives: it's free to answer but can lead to dissolution if left unanswered for 120 days.

FAQ
Do I need to publish in a newspaper to form an LLC in Arizona?
Only if your statutory agent's address is outside Maricopa or Pima county. If your agent is based in either county, Arizona's Public Notice database handles the requirement for free, and you can skip the newspaper step entirely. Outside those counties, you'll need 3 consecutive publications in an ACC-approved newspaper within 60 days of your Articles being approved.
Does Arizona require an annual report for LLCs?
No, Arizona doesn't require an annual report for LLCs, which is confirmed true for 2026. Starting in 2026, the Corporation Commission does run a January review for LLCs that have filed nothing in 2 years, sending flagged LLCs a free existence-confirmation notice. This is dormancy-triggered rather than a scheduled yearly filing most LLCs will ever encounter.
Why does Arizona use the Corporation Commission instead of the Secretary of State?
Arizona assigns business filings to the Arizona Corporation Commission rather than the Secretary of State, which handles this function in most other states. Since January 12, 2026, Articles of Organization and other ACC filings run through the new Arizona Business Center portal, which replaced the older eCorp system. Founders used to filing with a Secretary of State elsewhere should expect this naming difference when searching for Arizona's filing agency.
