How to form an LLC in Arizona: 7 steps
- 1
Name your Arizona LLC
Your name must be distinguishable from other Arizona businesses and include a designator such as “LLC” or “Limited Liability Company.” Avoid restricted words (like bank or insurance) unless you qualify. Search the official Arizona business database to confirm availability, then secure a matching domain before you file.
- 2
Appoint a registered agent
Arizona requires every LLC to maintain a registered agent with a physical street address in the state to receive legal notices and government mail. You can act as your own agent if you have a Arizona address and are available during business hours, or hire a service (around $125/year) for privacy and reliability — non-US founders generally must use a service.
- 3
File your formation documents
Officially create your LLC by filing your formation documents (commonly called the Articles of Organization) with the Arizona Secretary of State and paying the $50 state filing fee. Online filings are usually processed fastest; mailed filings take longer, and expedited processing is often available for an extra fee.
- 4
Create an operating agreement
An operating agreement isn’t always legally required, but every Arizona LLC should have one. It documents ownership, management, voting, and profit-sharing, and reinforces your liability shield — especially for multi-member LLCs. You can generate a free draft and have an attorney review it.
- 5
Get an EIN from the IRS
An EIN (federal tax ID) is free from the IRS and is needed to open a business bank account, hire employees, and handle taxes. U.S. founders with an SSN can apply online in minutes; non-US founders without an SSN can still get one by filing Form SS-4 by fax or mail.
- 6
Open a business bank account
Keep your business and personal finances strictly separate to protect your liability shield. Open a dedicated business bank account using your approved Arizona formation documents, your EIN, and your operating agreement.
- 7
Stay compliant year after year
Arizona does not require an annual report, which keeps ongoing paperwork light — but you still need to renew your registered agent and meet your federal and Arizona tax obligations to stay in good standing.

| Annual report | Not required | Arizona does not require LLCs to file an annual report. |
| Operating agreement | $0–$200 | Free with a DIY template, or more through a legal service. |

Annual report & ongoing compliance
Good news: Arizona does not require LLCs to file an annual report, so there’s no recurring report fee. You still need to keep a valid registered agent and stay current on your federal and Arizona taxes to remain in good standing.

Taxes for Arizona LLCs
By default, a Arizona LLC is a pass-through entity: the business itself usually pays no federal income tax, and profits flow to the owners’ personal returns. As an owner you’ll typically owe federal income tax plus self-employment tax (15.3% for Social Security and Medicare) on your share of the profit.
Arizona levies a state income tax, so your pass-through profits are generally subject to Arizona income tax in addition to federal tax. Confirm current rates and brackets with the Arizona Department of Revenue.
If you sell taxable goods or services, you may also need to register for and collect Arizona sales tax. Once profits are consistently high, it’s worth checking whether an S-Corp election could lower your self-employment tax.

Should you form your LLC in Arizona?
If you live or do business in Arizona, forming here is usually simplest — operating in a state typically means you have to register (and pay) there anyway. If you’re an online or non-US founder with no physical presence, it’s worth comparing Arizona with low-cost, privacy-friendly states like Wyoming and New Mexico.
