To amend your articles of incorporation, get the change approved internally, file Articles of Amendment (sometimes called a Certificate of Amendment) with your Secretary of State, and then update the IRS, your bank, your licenses, and anyone else who relies on the old record. The state filing is the legal act; the follow-up updates are what keep the change from causing problems weeks or months later. The same process, with slightly different internal approval rules, applies to LLCs amending their articles of organization.
When You Actually Need an Amendment
Amendments exist for structural changes to how the entity is defined in its founding documents. The common ones:
- A change to the legal name of the entity.
- Increasing or decreasing the number of authorized shares. This sets the ceiling on what the corporation can issue; it does not touch shares already held.
- Changing the stated business purpose, often from a narrow clause to a general one.
- For an LLC, switching between member-managed and manager-managed, because that changes who can bind the company.
Some updates look like amendments but aren’t. Changing your registered agent or registered office address usually uses a separate, shorter form that costs less and processes faster. And a DBA is not an amendment: a DBA lets you market under a trade name while your legal name stays the same on state records, contracts, and tax filings. If you want the name change to be permanent and binding on the entity itself, you need the amendment.
Get Internal Approval First
Nothing goes to the state until the change is properly authorized inside the company.
For a corporation, the board of directors adopts a resolution recommending the amendment, and then the shareholders vote on it. The standard threshold is approval by a majority of shares entitled to vote, though the articles or bylaws can require more. Certain changes, such as those that create appraisal rights for dissenting shareholders, can trigger stricter voting requirements.
For an LLC, the operating agreement controls. If it is silent, most state default rules call for a majority vote of the members. A single-member LLC can authorize the amendment through a written resolution signed by the sole member.
You usually do not have to hold a meeting. Most states let directors, shareholders, and members act by written consent if the consent is signed by at least as many votes as a meeting would have required. Date it, state the action, and keep it in the minute book. For a closely held business where everyone agrees, this is the practical path, and it carries the same legal weight as a meeting vote.
Preparing the Articles of Amendment
The form itself lives on your Secretary of State’s website. It is short, but filing offices reject anything vague or inconsistent with their records. You will need:
- The current legal name of the entity, character for character as it appears on file.
- The entity ID number (sometimes called a Charter Number, filing number, or Secretary of State ID).
- The specific article being changed and the exact replacement language.
- The date the board, shareholders, or members approved the amendment.
- A signature from an authorized officer (corporation) or authorized member or manager (LLC).
Draft the amendment language so the filing officer has no interpretive work to do. Identify the article by number and give the full replacement text: “Article III is hereby amended to read in its entirety as follows:…” works. The most common rejection reasons are missing signatures, a signature from someone who is not actually an officer of record, missing authorization dates, wrong fees, outdated forms, and vague descriptions of the change.
Checking Name Availability
If the amendment changes the entity’s name, the state will reject anything that is not distinguishable from a name already on file, and most states require the name to include an entity identifier like “LLC,” “Inc.,” or “Corporation.” Run the proposed name through your Secretary of State’s online database before you file.
Check the USPTO’s trademark database too. A name can clear the state and still expose you to a federal trademark infringement claim if someone else owns the mark. Discovering that after you have changed bank accounts and reprinted everything is an expensive problem.
Filing, Fees, and Timing
Most states accept amendments online or by mail. Online portals typically process filings within one to three business days and return electronic confirmation. Paper filings with a check can take several weeks, depending on the state’s backlog.
Filing fees for amendments range from roughly $10 to $220 depending on state and entity type, with most falling between $25 and $60. Expedited processing is widely available for an extra $25 to $750, which buys same-day or 24-hour turnaround when a deal or financing is on the clock.
Once the state approves the filing, you will receive a file-stamped copy or a formal Certificate of Amendment. Put it in the minute book. You will need it again every time you update a bank account, license, or contract.
If the filing is rejected, the state sends a deficiency notice explaining why. The rejection is fixable, but the delay is not. A stalled amendment in the middle of a closing, a financing round, or an investor onboarding can hold up the entire transaction.
Notifying the IRS
State approval is the midpoint. The IRS process for a name change does not use the form most people reach for.
Form 8822-B changes your business address or responsible party. It does not change your business name. For a name change, a corporation checks the name-change box on its annual return: Line E, Box 3 on Form 1120, or Line H, Box 2 on Form 1120-S. A partnership checks Line G, Box 3 on Form 1065. If the current year’s return has already been filed, send a signed letter to the IRS at the address where the return was filed, notifying it of the change. Sole proprietors use the same letter approach. The letter must be signed by a corporate officer, a partner, or the business owner, depending on the entity type.1Internal Revenue Service.

If the amendment also changes your business address or responsible party, that is where Form 8822-B comes in. File it separately from the name-change notification.2Internal Revenue Service. About Form 8822-B, Change of Address or Responsible Party – Business
Does the Amendment Trigger a New EIN?
A name change alone does not. Neither does an address change or a change of officers. Certain structural changes do:
- A corporation needs a new EIN when it receives a new charter from the secretary of state, changes to a partnership or sole proprietorship, or merges to create a new corporation. Converting to S corporation status or surviving a merger does not require one.
- An LLC needs a new EIN when it terminates and a new entity forms, or when a single-member LLC begins having employment or excise tax obligations. A partnership-classified LLC making an S corporation election does not need one.
- A partnership needs a new EIN when it incorporates, when one partner takes over as a sole proprietor, or when the existing partnership ends and a new one begins.
- A sole proprietor needs a new EIN when incorporating or forming a partnership.
The test is whether the entity’s fundamental structure changed. If the amendment converts your entity type or creates a new legal person, apply for the new EIN before filing your next return.3Internal Revenue Service. When to Get a New EIN
Updating Everyone Else
The downstream updates are where amendments quietly fail. Each one is small; missing them tends to surface at the worst time, like an insurance claim or a loan application.
Banks and financial institutions. Bring the certified Certificate of Amendment to update account names and signature cards. Some banks will freeze an account until they receive it. Lines of credit, merchant processing accounts, and corporate credit cards all need the same update.
Licenses, permits, and insurance. Local business licenses, professional permits, and industry registrations all need the current legal name and structure. Insurance is the one that stings: a policy naming the wrong entity can result in a denied claim, because the insurer’s obligation runs to the named insured. Contact every carrier and update the named insured as soon as the amendment is approved.
Trademarks. If you hold registered trademarks, record a name change through the USPTO’s Assignment Center with a cover sheet and supporting documentation. The USPTO recommends checking the Trademark Status and Document Retrieval system after about a week to confirm the update propagated; if it did not, submit the TEAS form appropriate to your registration’s current status.4United States Patent and Trademark Office. Trademark Assignments: Transferring Ownership or Changing Your Name
Foreign qualifications. If you are registered to do business in states beyond your home state, each of those registrations needs its own update. Usually that means filing an amendment to the certificate of authority or a separate name-change form in each foreign state. Fees and timelines vary. Operating under an outdated name in a foreign state can affect your authority to do business or enforce contracts there, so do not let these drift.
What Happens If You Skip the Amendment
The consequences are rarely immediate, which is why they get ignored. They compound. Operating under outdated articles means the public record no longer matches reality. States can administratively dissolve entities that fail to maintain current filings, and a dissolved entity has no legal authority to do business. Owners who keep operating through a dissolved entity put the liability shield at risk, because creditors can argue the corporate formalities were abandoned.
Short of dissolution, an outdated record can block new bank accounts, real estate closings, and business loans. Title companies and lenders pull Secretary of State records during due diligence, and any discrepancy between your filed documents and your operating reality will stall or kill the transaction. The amendment itself is one of the cheaper filings a business makes. Not filing it tends to cost much more.
