Articles of amendment are the formal document a business files with the secretary of state to change information in its original formation records. For a corporation, that original record is the articles of incorporation; for an LLC, it’s the articles of organization. Whenever a fact the state required you to put on file no longer matches reality, you file articles of amendment to bring the public record current and keep the entity in good standing.
Changes That Require an Amendment
The test is simple. If the information you’re changing appears in your original formation documents, you almost certainly need to amend. If it doesn’t appear there, you probably don’t.
The common triggers:
- A new legal name for the entity. This is the single most frequent reason businesses file.
- A change to the stated business purpose, if one was specified in the original filing.
- For corporations, changes to the stock structure: altering the number of authorized shares, creating new classes or series, or changing par value.
- Changes to management structure, such as adjusting the number of directors (when that number is stated in the articles) or switching an LLC between member-managed and manager-managed.
- Converting from one entity type to another, such as an LLC becoming a corporation.
Some states also require an amendment when the names of directors, members, or managers change, though most handle those updates through the annual report. Compare your current situation line by line against what your formation documents actually say. Any mismatch in a detail the state required is a likely amendment.
Changes That Don’t Need an Amendment
Several routine changes look like they’d require an amendment but don’t, and businesses waste money filing them this way.
Changing your registered agent is handled through a separate Statement of Change form in nearly every state, with its own (usually lower) fee. The same goes for updating a registered agent’s address. Filing a full amendment for an agent swap is overkill and can even slow the change down.
Principal office address changes are typically reported through annual reports or a simple address-change form, unless your state specifically required the address in your original formation documents. Changes to officers, day-to-day managers, or internal operating agreement terms generally don’t touch the articles either.
Get Internal Approval First
Before anything goes to the state, the people who run the business have to formally authorize the change. This matters because the state will file your amendment based on the signature alone. If the amendment wasn’t properly authorized internally, you’ve created a governance problem that doesn’t go away just because the filing was accepted.
For corporations, approval usually happens in two stages. The board passes a resolution recommending the amendment, then shareholders vote to approve it. Most states require at least a majority of the shares entitled to vote, and some amendments (changes to stock rights, for instance) may require separate approval from each affected class. Your articles of incorporation or bylaws might set a higher threshold, so check both before scheduling the vote.
For LLCs, the operating agreement controls. Some states default to unanimous member consent for amendments; others require only a majority. If the operating agreement sets a threshold, that governs. If it’s silent, the state’s LLC statute fills the gap.
Whatever the entity type, document the approval in writing. Keep the board resolution, meeting minutes, or written consent on file. Some states require you to describe or certify the approval process on the amendment form itself.
What Goes on the Form
Most states provide a standardized amendment form on the secretary of state’s website. The required information is fairly consistent:
- The entity’s current legal name, exactly as it appears in the state’s records.
- The new legal name, if the amendment changes it. It must be distinguishable from existing entity names on file.
- The original formation date or state-issued filing number, so the agency can locate the correct record.
- The text of the amendment itself. Most forms ask you to state the provision as amended rather than describe the change in the abstract.
- The effective date. Many states let you specify a future effective date, often up to 90 days after filing. Leave it blank and the amendment typically takes effect the moment the state accepts it.
- An authorized signature, usually from an officer for a corporation or a manager or authorized member for an LLC.
Double-check the name on file before submitting. Even a minor discrepancy between the name on your amendment and the name in the state’s database can trigger a rejection. If you’ve filed previous amendments, reference the most current version of the articles, not the original.
Fees and Processing Time
Every state charges a fee, and the range is wider than most people expect. Fees run from as low as $5 to $10 in a handful of states up to $200 or more in others, with most falling somewhere in the $25 to $100 range. Some states charge a flat fee regardless of the change; others adjust the cost based on what’s being amended, with stock-structure changes sometimes carrying a higher fee. Check your state’s fee schedule before submitting.
Most states now offer online filing through the secretary of state’s portal, which is usually the fastest route. Mail and in-person filing remain available in many places. Online filings are often processed within a few business days, while mailed filings can take several weeks depending on the agency’s backlog.
Once the state processes the amendment, you’ll receive confirmation, either a stamped copy of the filed document or a digital acknowledgment. Keep this with your corporate records. Consider ordering a certified copy as well; banks, lenders, and business partners sometimes ask for one, and the fee is typically modest, often under $20.
What to Do After You File
Filing with the state is the first step, not the last. A name change, address change, or structural change ripples through nearly every registration and relationship the business has.
Tell the IRS
A name change does not require a new Employer Identification Number. The IRS is explicit: you keep your existing EIN when you change the business’s name or location, regardless of entity type.1Internal Revenue Service. When to Get a New EIN You do have to notify them. For corporations, S corporations, and multi-member LLCs, the simplest method is checking the “name change” box on your next tax return (Form 1120, 1120-S, or 1065). If you’ve already filed for the year, send a written notice signed by an officer, member, or partner to the IRS office where you file.
For an address change, use Form 8822-B. The same form handles changes to the business’s “responsible party,” which must be reported within 60 days.2Internal Revenue Service.

A new EIN is only required when the business structure itself fundamentally changes, such as incorporating a sole proprietorship, converting a corporation to a partnership, or forming a new entity after a merger.1Internal Revenue Service. When to Get a New EIN
Update State, Local, and Foreign Registrations
Notify your state’s department of revenue, update professional licenses and permits, and amend any DBA filings that reference old information. If the business is registered as a foreign entity in other states, each of those states needs its own amendment or notification.
Update Banks, Vendors, and Contracts
Banks typically require a certified copy of the filed amendment plus a new board resolution or member consent before updating your account. Notify insurers, landlords, vendors, utilities, and any lender holding a note. Existing contracts generally stay enforceable after a name change because the legal entity itself hasn’t changed, but telling counterparties proactively prevents confusion over invoicing and payment.
When to Restate Instead of Amend
Each amendment adds another layer to your corporate record. After two or three, anyone reviewing the file has to piece together the original articles plus every successive amendment to figure out your current structure. Restated articles solve that by consolidating everything into a single clean document that replaces the originals and all prior amendments.
The legal effect is the same, but the result is much easier to read. Lenders, investors, and buyers doing due diligence strongly prefer one restated document over a stack of individual filings. As a practical rule, if you’re on your third or fourth amendment, or if the current change touches multiple provisions, restating is usually worth the effort. Filing fees for restated articles vary and may run slightly higher than a simple amendment.
What Happens If You Don’t File
Operating with outdated formation documents on file causes problems that compound. Specifics vary by state, but several consequences are common.
The most immediate risk is losing good standing. States can revoke good standing status for noncompliance with filing requirements, and once an entity falls out of good standing it may be barred from bringing lawsuits in that state’s courts until the issue is cured. Lenders and investors routinely require a certificate of good standing before approving financing, and a lapsed status signals risk. In many states you can restore compliance and proceed with your claims, but the delay itself can be costly.
Deeper noncompliance can lead to administrative dissolution, where the state cancels the entity’s existence. A dissolved entity may lose its limited liability protection, exposing owners’ personal assets. It can also lose the rights to its name if another entity registers something similar during the dissolution.
Even short of dissolution, inaccurate public records create friction. Banks may freeze accounts when the information on file doesn’t match. License renewals stall. And in a dispute, opposing counsel will point out that your entity’s public records are wrong, which never plays well in front of a judge.
