Commercial RA cost

~$100/yr

Arizona Articles of Organization do not require member names on the public filing for member-managed LLCs — only the registered agent address is publicly disclosed. This provides better member privacy than Illinois or California. The ACC eCorp portal shows RA name and address; using a commercial RA service keeps your personal address off the public record entirely.

1. Check name availability with the Arizona Corporation Commission Search the ACC entity name database at azcc.gov to confirm your desired LLC name is available and not deceptively similar to an existing Arizona entity. The name must include a valid designator (LLC, L.L.C., Limited Liability Company, Limited Liability Co., LC, or L.C.). Optional: reserve the name for 120 days ($10) while you prepare documents.
2. Appoint an Arizona registered agent Designate a registered agent with a physical Arizona street address (no PO boxes). AZ residents may self-serve as RA. Out-of-state owners — including many Phoenix real-estate investors and remote entrepreneurs — use a commercial RA service ($50–$150/yr). The RA is the only ongoing compliance obligation for an Arizona LLC (no annual report requirement).
3. File the Articles of Organization ($50) with the AZ Corporation Commission File online at azcc.gov. The Articles require the LLC name, registered agent information, principal address, management structure (member-managed or manager-managed), and organizer signature. Pay the $50 filing fee. Standard online processing: 14–16 business days; expedited 3–5 business days for an additional fee.
4. Confirm publication exemption (Phoenix/Maricopa County — no publication required) Arizona LLC law requires 3-week newspaper publication for LLCs with principal offices in counties under 800,000 population. Phoenix is in Maricopa County (4M+ residents), which is exempt. No publication step is required for Phoenix LLCs. If you later move the LLC's principal address to a rural AZ county, the publication requirement would activate — consult the ACC or the Arizona Revised Statutes § 29-3201 for current county population thresholds.
5. Draft an Operating Agreement Arizona's LLC Act (ARS § 29-3101 et seq.) provides default rules, but an Operating Agreement is critical for Phoenix LLCs with multiple investors, real-estate holdings, or variable management structures. The OA should define ownership percentages, voting rights, profit/loss allocations, buyout terms, and what happens on member exit or death.
6. Obtain an EIN from the IRS After the Articles of Organization are approved, apply for an EIN at irs.gov/ein. The online application takes under 15 minutes and provides the EIN immediately. Print the CP 575 EIN Confirmation Letter for bank account opening.
7. Obtain a Phoenix TPT license and register for Arizona Transaction Privilege Tax If your Phoenix LLC conducts retail sales, restaurant operations, contracting, or other TPT-taxable activities, register with the Arizona Department of Revenue (ADOR) for a Transaction Privilege Tax (TPT) license at aztaxes.gov. The combined Phoenix retail TPT rate is approximately 8.6% (AZ state 5.6% + City of Phoenix 2.3% + Maricopa County 0.7%). The Phoenix city privilege license fee is $2/location/year — essentially nominal. Note: Arizona's TPT is a tax on the seller (applied to gross receipts), not on the buyer — this differs from the traditional sales-tax model used in Texas, Florida, and most other states.
8. Maintain registered agent status (the only ongoing obligation) Arizona LLCs have no annual report. The only compliance obligation after formation is keeping registered agent information current with the ACC. If your RA moves, resigns, or becomes unavailable, update the RA immediately via the ACC eCorp portal. Lapsing registered agent coverage is the one administrative event that can put an Arizona LLC in jeopardy. No annual fee, no report, no franchise filing.
9. Open a business bank account Bring your EIN Confirmation Letter, Articles of Organization, and Operating Agreement to the bank. A separate business account is essential for maintaining the LLC's liability shield. Phoenix-area banks (Chase, Bank of America, Western Alliance, Desert Financial) require an EIN and formation documents for business account opening.

Formation context

Who should form in Arizona?

Recommended for

Phoenix-area entrepreneurs, real-estate investors, and remote-work business owners who want zero recurring state filing overhead; Sun Belt businesses in real estate, construction, healthcare, hospitality, and professional services that operate primarily in the Phoenix metro; Out-of-state owners forming an AZ entity for Southwest operations — Arizona's $0 annual report and $50 formation fee make it the lowest-cost major-metro LLC environment in the US

Tax treatment (default)

Pass-through by default at the federal level: single-member LLCs are disregarded entities (Schedule C); multi-member LLCs are partnerships (Form 1065). Arizona taxes pass-through LLC income at the individual member level via the 2.5% flat Arizona income tax — the lowest flat rate in the US. Arizona imposes no franchise tax and no annual LLC filing fee. The AZ Transaction Privilege Tax (TPT) applies to gross receipts from certain business activities (retail, contracting, restaurants) — separate from income tax.

For businesses operating in Phoenix, forming directly in Arizona ($50, no annual report) avoids the dual-state cost of Wyoming or Delaware formation plus AZ foreign qualification (~$150). Arizona's $0 annual report means a Wyoming LLC's $60/yr minimum + AZ foreign qualification fee exceeds direct AZ formation costs within 2 years. Formation-state advantages (WY charging-order, DE Court of Chancery) apply primarily to holding structures and investor-facing entities — not to operating Phoenix businesses.

No publication requirement in Arizona — unlike New York or Nebraska, you do not need to publish notice in a newspaper after filing.

FAQ

Common Arizona (Phoenix) LLC formation questions

Still deciding between an LLC, sole proprietorship, S-Corp, or C-Corp? Our entity-type comparison breaks down formation cost, tax treatment, liability shield, and compliance complexity for all four structures side by side.

Once your LLC clears ~$80K in annual net profit, an S-Corp election (IRS Form 2553) typically saves $5,000–$15,000/year in self-employment taxes by splitting owner income into a W-2 salary + tax-free distributions. The election is free — Form 2553 has no IRS filing fee. The key decision factors: your net income level, a defensible reasonable-compensation salary, and the 75-day Form 2553 filing window after LLC formation.

Already operating as a sole proprietor, or wondering whether a cheap county DBA filing ($10–$100) is enough instead of forming an LLC? A DBA lets you operate under a trade name — but provides zero liability protection. Our DBA vs LLC comparison breaks down exactly when a DBA is sufficient and when you need a state LLC filing.

Missing your annual report deadline triggers late fees and — if left long enough — administrative dissolution, which voids your LLC's liability shield until reinstated. Know your Arizona deadline, fee, and the consequences of missing it.

Also see the LLC annual report requirements hub for state-by-state deadlines, fees, late penalties, and reinstatement rules.

If your LLC opens an office, hires employees, or regularly does business in another state, you must foreign-qualify there — or face fines, back taxes, and loss of standing to sue. Our foreign qualification guide covers when you need it, how to file a Certificate of Authority, and what it costs.

Your Articles of Organization are filed — now make your LLC operational. Four actions every new LLC owner needs to take:

Formation gets your LLC into existence; contracts, trademark protection, operating agreement review, and vendor-document review keep it usable. Compare subscription and per-document legal platforms before you rely on a template or pay a local attorney retainer.

Commingling personal and business funds is the #1 way LLC owners lose their liability shield. A separate business account — in your LLC's legal name, with your EIN — is the foundational act of corporate formality. Mercury, Novo, Bluevine, Relay, and Found open same-day with no monthly fees. Compare online banks vs. Chase and Bank of America.

How you pay yourself depends on your LLC's tax classification — not what you call the transfer. A disregarded single-member LLC pays via owner draw with SE tax on all net profit. An S-Corp-elected LLC splits income between a W-2 salary (FICA applies) and tax-free distributions. Getting this wrong triggers IRS audit risk and SE-tax errors.

Single-member LLCs file Schedule C with their personal Form 1040 (due April 15). Multi-member LLCs file Form 1065 by March 15. S-Corp-elected LLCs file Form 1120-S by March 15. Know your form, your deadline, and the common deductions — home office, vehicle, retirement contributions, and startup costs — before your first April filing.
