What an amendment in Arizona actually does.
What needs an amendment
Entity name changes, principal office address changes, registered agent changes, member or manager additions / removals, change in purpose or NAICS, change in management structure.
Articles of Amendment
Arizona calls it the Articles of Amendment. Filed with the SOS, signed by an authorized member or manager, includes both the before and after values for clarity.
Typical processing time
Arizona SOS typically processes amendments in 3 to 10 business days for online filings. Expedited service is available in most states for an additional fee.
Risks of not filing
Banks can refuse account changes if SOS record does not match. Lenders flag in diligence. Service of process can be delivered to old addresses. Outdated officer records can muddy authority.

Common questions.
What is the Articles of Amendment in Arizona?
The Articles of Amendment is the official Arizona Secretary of State document for updating your entity record. Filed any time something on file (name, address, RA, members, purpose) changes.
When do I need to file an amendment in Arizona?
Entity name changes, principal office address changes, registered agent changes, member or manager changes, purpose / NAICS changes, conversions to a different entity type. Some routine changes (mailing-only address) may not require an amendment.
How much does an amendment cost in Arizona?
Arizona's state filing fee for the Articles of Amendment is $25. Our service fee is separate (see pricing above). Expedited processing adds an additional state fee in most cases.
How long does Arizona take to process amendments?
Standard processing is typically 3 to 10 business days for online filings. Arizona offers expedited service for an additional fee.
Do all members need to sign?
Signing requirements depend on your operating agreement or bylaws. Most Arizona LLCs require a member vote (majority or supermajority depending on the agreement). We provide consent templates and walk you through the requirement.
What if I need to update multiple things at once?
You can usually combine multiple changes in a single amendment filing. Saves a state fee. We bundle them automatically when you file through File.Business.
Do I need to amend my Operating Agreement separately?
Yes. The Articles of Amendment updates the state record. Your Operating Agreement is a separate internal document; if the change affects rights, voting, or member relations, update the Operating Agreement at the same time. We can draft the OA amendment alongside.
What happens to my EIN after a name change?
Your EIN stays the same. You notify the IRS of the name change by letter (or on the next tax return). Banks typically want a copy of the stamped Articles of Amendment before updating their records.
Do I need to file amendments in other states where I am foreign qualified?
Yes. If you are registered as a foreign entity in other states, you must also file amendments in each of those states for the same change. We handle multi-state amendment cascades on the Compliance Bundle and Business OS.
