How to Start a Corporation in Arizona

Incorporating in Arizona takes about two weeks and costs $60 to file. This guide walks you through exactly what you need, the filing process, and what comes after. Whether you're choosing a corporation for liability protection, tax treatment, or investor credibility, the Arizona Corporation Commission has streamlined the process to make it straightforward.

Understanding Arizona Corporations

A corporation is a legal entity separate from its owners. In Arizona, you'll likely be forming a for-profit corporation (sometimes called a C-corporation). This structure gives you limited liability protection, meaning personal assets are generally protected from business debts and lawsuits.

Arizona corporations are taxed at 4.9 percent of net income or $50, whichever is greater. A few businesses elect S-corporation status for federal tax purposes to pass income through to owners at the lower individual rate of 2.5 percent, but that's a federal election made after incorporation, not part of the Arizona filing.

The main trade-off: corporations involve more paperwork than LLCs. You'll file annual reports every year, maintain corporate formalities like board meetings, and handle more complex tax filings. If you want simplicity and pass-through taxation, an LLC might be a better fit. If you need a recognized business structure for investors or credibility, a corporation is worth the extra work.

What You'll Need Before Filing

Gather these items before you start the incorporation process:

• A business name. It must include the word "Corporation," "Incorporated," "Corp," "Inc," or a similar indicator. Check availability on the Arizona Business Center at arizonabusinesscenter.azcc.gov/businesssearch.
• A statutory agent. This person accepts legal papers on behalf of your corporation. The agent must be an Arizona resident with a permanent street address in the state, or you can use a registered agent service (typically $100 to $300 per year).
• Principal office address. This is where your corporation's main office is located. It does not have to be in Arizona.
• The $60 filing fee. Pay this when you file the Articles of Incorporation through the Arizona Business Center.
• Basic corporate details. Number of authorized shares (often a round number like 1,000), share class (usually just common stock), and par value (often zero or $0.01).

Step-by-Step: How to Incorporate in Arizona

Step 1: Reserve or Verify Your Business Name

Before filing, confirm your name is available. Go to Arizona Business Center's business search tool and enter your proposed name. The system checks against all registered Arizona entities.

If your name is available but you want to lock it in while you prepare other documents, you can reserve the name for 120 days by filing a Name Reservation form and paying a $10 fee. This gives you breathing room without rushing the Articles of Incorporation.

Step 2: Prepare Your Articles of Incorporation

The Arizona Corporation Commission provides a standard Articles of Incorporation form. You'll include:

• Corporation name (with the incorporation indicator: Corp., Inc., Incorporated, or Corporation)
• Number of authorized shares
• Address of principal office (Arizona or out of state, both are fine)
• Name and Arizona street address of statutory agent
• Name and address of the incorporator (usually the person filing)

The statute that governs this is A.R.S. 10-2402. You do not need to include bylaws, director names, or stock ownership details in the Articles themselves. Those go in separate corporate records you keep internally.

Step 3: Prepare a Certificate of Disclosure

Arizona requires a Certificate of Disclosure filed alongside the Articles of Incorporation. This form asks for basic information about the corporation's structure and typically takes two minutes to complete. The Arizona Corporation Commission includes a template on their website at azcc.gov/corporations.

Step 4: File Through the Arizona Business Center

Go to Arizona Business Center (ABC). You can file online, which is the fastest and easiest route. Upload your Articles of Incorporation and Certificate of Disclosure, pay the $60 filing fee with a credit card or bank account, and submit.

The system assigns your filing a reference number immediately. You can check the status anytime by logging back into the portal.

Step 5: Wait for Examination

Standard processing takes about 9 to 11 business days. The Corporations Division reviews your documents for completeness and compliance. If something is missing or incorrect, they'll email you with the issue and ask you to fix it. If everything is in order, they'll approve your Articles and issue a Certificate of Incorporation.

If you need faster service, Arizona offers expedited processing (2 to 4 business days) for $35 extra. Same-day service (by 5 p.m. the same day) costs $100 additional, and two-hour service (8 a.m. to 3 p.m. only) costs $400. These accelerated options expedite the examination window, not the approval itself.

Step 6: Receive Your Certificate of Incorporation

Once approved, the Arizona Corporation Commission emails your Certificate of Incorporation as a PDF and mails an official certificate. You now have legal authority to operate. This certificate proves you're incorporated and is useful for opening bank accounts, getting business licenses, and establishing credibility.

What Happens Immediately After Incorporation

Your corporation exists on the date the Certificate of Incorporation is issued. That's the day you can start conducting business. However, several next steps are critical:

Open a Business Bank Account

Bring your Certificate of Incorporation and employer identification number (EIN) to the bank. If you do not yet have an EIN, apply for one free at IRS.gov (takes 15 minutes online or up to two weeks by mail). Most banks now process EINs instantly online so you can open an account the same day.

Get an Employer Identification Number (EIN)

Even if your corporation has no employees, you'll need an EIN to file tax returns and open business accounts. Apply online at the IRS website for instant approval.

Register for Transaction Privilege Tax (TPT)

If your corporation sells taxable goods or services, you must register for a Transaction Privilege Tax license with the Arizona Department of Revenue at azdor.gov. This license costs $12 per location. Sales tax starts collecting the day you begin business, so do not delay this step.

Update Your Statutory Agent

If your statutory agent changes or moves, you must file an amended designation with the Corporation Commission. This form costs $5 and must be filed promptly. An expired agent address can lead to administrative dissolution if the state cannot serve you notice.

Adopt Corporate Bylaws

While not filed with the state, bylaws are essential internal documents. They govern how the corporation operates: board meetings, shareholder voting, officer roles, and share transfers. Most small corporations adopt basic bylaws and file them in a corporate records book. This is not state-required but is strongly recommended for liability protection.

Ongoing Requirements and Costs

Annual Report

Arizona corporations must file an Annual Report every year. The report is due in your corporation's anniversary month (the month your Certificate of Incorporation was issued). The filing fee is $45 per report. If you miss the deadline, the state can administratively dissolve your corporation. Filing is straightforward and takes 10 minutes through the Arizona Business Center.

Annual Tax Return

File Arizona Corporation Income Tax return Form 120 by the corporation's tax year deadline (usually April 15 if you use the calendar year). You owe tax at 4.9 percent of net income or $50, whichever is greater. This is in addition to federal corporate tax returns.

Maintaining Agent and Address

Keep your statutory agent and principal office address current. If your agent moves out of state or resigns, you have 30 days to file a new agent or face administrative dissolution. This is a common trap that dissolves corporations nobody is monitoring.

Common Mistakes to Avoid

Using the wrong name format. "Technology Innovations" fails; "Technology Innovations Inc." passes. The incorporation indicator (Inc., Corp., Incorporated, Corporation) must be in the name. This is non-negotiable.

Forgetting the statutory agent. A corporation without a valid statutory agent is administratively dissolved. Do not skip this. If you use a registered agent service, verify they file the Acceptance of Appointment form on time.

Missing the annual report deadline. Set a calendar reminder for your anniversary month. The dissolution is automatic if you miss the deadline, and reinstatement is messy and costly.

Mixing personal and corporate funds. Keep corporate and personal finances separate. Deposit all revenue into the corporate account and pay all business expenses from it. Mixing funds can pierce the liability shield in a lawsuit.

Ignoring corporate formalities. Hold at least one board meeting per year, keep minutes, and document major decisions. Courts look at these records if someone sues. If you ignore formalities, a judge may ignore the corporate structure and go after personal assets.

Choosing a corporation to avoid taxes. Corporations do not pay less tax than LLCs in Arizona. Both are pass-through entities if structured correctly for federal tax purposes. Choose a corporation for liability protection and formality, not for tax savings.

Should You Incorporate or Form an LLC?

This depends on your business structure and goals. Incorporate if you plan to raise investor funding, want to go public, need to issue stock to employees, or prefer formal governance. The corporate structure signals stability to outside investors.

Form an LLC if you want simplicity, fewer annual filings, and less rigid governance. LLCs also have no annual report requirement in Arizona, so the only recurring cost is your business license. Both offer liability protection.

Talk to a tax professional about the optimal choice for your situation. S-corporation tax elections and entity selection have nuances that depend on your income, owner structure, and future plans.

Important Legal Disclaimer

This guide is informational only and not legal or tax advice. Incorporation involves specific state statutes and tax consequences that vary by situation. Consult a qualified attorney licensed in Arizona and a CPA before incorporating, especially if you plan to raise capital, have multiple owners, or operate in a regulated industry.

Next Steps

Once you're incorporated, your immediate priorities are opening a business bank account, obtaining an EIN and TPT license, and adopting corporate bylaws. From there, focus on separating personal and business finances, holding annual board meetings, and filing your annual report on time.
