How to Form an Arizona Corporation — Step by Step

Your corporate name has to be distinguishable from every other business entity already on file with the Arizona Corporation Commission. "Distinguishable" is a legal standard — a name that differs only by punctuation, spacing, or a filler word like "the" or "and" may still collide with an existing entity and get rejected.

Start with the name search on the Corporation Commission's site. Search your exact proposed name and close variations, and note anything that reads or sounds similar. A rejection over a name conflict wastes days, so it's worth being thorough before you file.

Naming rules for Arizona corporations

• Must contain a corporate indicator — "Corporation," "Incorporated," "Company," or "Limited," or an abbreviation such as "Corp.," "Inc.," "Co.," or "Ltd."
• Cannot contain "association," "bank," "deposit," "credit union," "trust," or similar restricted words without approval from the relevant regulator
• Cannot imply a purpose the corporation isn't authorized to carry out, or falsely suggest a government affiliation
• Must be distinguishable from other names on record with the ACC

Optional: reserve the name

If you're not ready to file but want to hold the name, you can reserve it with the ACC for a set period for a small state fee. Reservation doesn't create the corporation; it just parks the name while you handle the rest.

Before you file, you need a statutory agent lined up and willing to serve. Arizona uses the term "statutory agent" for what most states call a registered agent. The agent is named in the Articles and must formally consent by signing the statutory agent acceptance (Form M002), which is filed alongside the Articles.

Arizona law requires every corporation to maintain a statutory agent with a physical Arizona street address for the life of the entity. The agent receives lawsuits, subpoenas, and official Corporation Commission correspondence on the corporation's behalf.

Who can serve

• An individual with an Arizona address: A director, officer, or trusted person with a physical Arizona street address (no P.O. box) who's available during business hours. Their address becomes part of the public record.
• A commercial statutory agent service: A business authorized to act as statutory agent in Arizona. A commercial service keeps its professional address on the public record instead of yours and guarantees someone is always available to receive documents.

The corporation cannot serve as its own statutory agent. If you use your home address, expect it to be searchable in the ACC database — a common reason owners choose a commercial service.

The Articles of Incorporation is the filing that creates your corporation in Arizona's official records. As of January 2026 you file through the ACC's Arizona Business Center portal at azcc.gov/corporations. The state filing fee covers the Articles; expedited processing is available for an additional state fee.

What goes in the Articles

• Corporate name with the required indicator (Inc., Corp., etc.)
• Character of business — a short description of what the corporation will do
• Authorized shares — the total number of shares the corporation may issue, and the classes/series if you have more than one
• Known place of business in Arizona (can be the same as the agent's address; a P.O. box alone won't do for the principal address)
• Statutory agent name and Arizona street address, plus the signed acceptance (Form M002)
• Directors — names and addresses of the initial board members
• Incorporators — the person or people signing and submitting the Articles

Certificate of Disclosure

Arizona also requires a Certificate of Disclosure with the Articles, in which the incorporators affirm that no officer, director, trustee, or major shareholder has a relevant history of certain securities or fraud judgments. It's a standard part of the Arizona incorporation packet — not a hurdle for a clean, ordinary business.

Standard processing runs a couple of weeks; expedited service turns it around much faster.

Arizona is one of the few states that requires newspaper publication after incorporation. Once the ACC approves your Articles, you must publish a notice of incorporation in an ACC-approved newspaper in the county of your known place of business, for three consecutive publications, within the required window after approval.

The county exemption

If your corporation's known place of business is in Maricopa County or Pima County, you're exempt — the Corporation Commission posts the notice on its own database in lieu of newspaper publication, and you don't have to do anything further. Every other Arizona county requires the newspaper step.

After publication, the newspaper issues an affidavit of publication. Keep it with your corporate records. Failing to publish when required can jeopardize the corporation's good standing, so don't skip it if your county isn't exempt.

Filing the Articles creates the shell of the corporation; the organizational meeting turns it into a functioning company. This is the step that most first-time incorporators overlook, and it's central to keeping the liability shield intact.

What happens at the organizational meeting

• Adopt corporate bylaws — the internal rulebook governing meetings, voting, officer roles, and share transfers
• Elect the board of directors (if not already named in the Articles) and appoint officers — typically a president, secretary, and treasurer
• Authorize and issue stock to the founding shareholders in exchange for their capital contributions, and record the issuances in the stock ledger
• Approve the corporate seal, bank resolution, and fiscal year, and authorize opening a bank account
• Adopt the S-corporation election decision if the corporation intends to elect S status

Document everything in written minutes and store them in the corporate minute book. For a single-owner corporation, you can accomplish all of this by written consent, but you still have to actually do it — the paperwork is what proves the corporation is a real, separate entity.

An Employer Identification Number is the corporation's federal tax ID — a nine-digit number the IRS issues at no charge. Every corporation needs one, because a corporation always files its own federal return (Form 1120 for a C-corp, Form 1120-S for an S-corp) and can't use an individual's Social Security number.

How to apply

File online using the IRS EIN Assistant over at IRS.gov. About ten minutes in, the number is assigned right away, leaving you free to open a bank account or submit the S-corp election that same day. The online application requires a US Social Security number or ITIN for the responsible party. If the responsible party has neither, apply by fax or mail using Form SS-4.

Once you have the EIN, you can file Form 2553 to elect S-corporation status if that's your plan — generally within about two and a half months of formation for it to apply to the first tax year.

Separate finances are non-negotiable for a corporation. Paying personal expenses out of the corporate account, or vice versa, is exactly the kind of commingling that lets a creditor argue the shield should be disregarded.

What banks typically want

• Filed Articles of Incorporation from the ACC
• IRS EIN confirmation letter
• Corporate bylaws and a banking resolution from the organizational minutes
• Government-issued ID for the authorized signers

Ongoing compliance

• Annual report to the Corporation Commission on the anniversary of formation, confirming officers, directors, known place of business, and statutory agent
• Corporate meetings and minutes — at least annual shareholder and director meetings (or written consents), recorded in the minute book
• Statutory agent maintenance — update the ACC promptly if the agent changes
• Tax filings — federal Form 1120 or 1120-S, an Arizona corporate return with the Department of Revenue, and TPT registration if you sell taxable goods
• Licenses and permits — Arizona has no general state business license, but many industries and cities require their own licensing, on their own cycles
