Articles of Amendment: How to Change Your LLC or Corporation's Filing

The most common reasons to file one: changing the business's legal name, changing the registered agent, changing the principal office or mailing address, and — for corporations — changing the number of authorized shares. Adding or removing members, or changing how the entity is managed, can also require an amendment in some states, depending on what was originally listed on the formation document.

In many states, a single amendment form covers all of these changes. But a meaningful number of states carve out a separate, simpler form specifically for a registered agent or address change — Michigan's Certificate of Change of Registered Office/Agent and New York's dedicated registered-agent-address form are two examples — rather than routing that change through a general amendment. Filing the wrong form can mean the state rejects it, so confirm which form your state actually wants before submitting anything.

A trade name or DBA change is a separate filing altogether, typically with different requirements than a formation-document amendment, and isn't something Articles of Amendment covers.

Find the correct form on your state's Secretary of State (or equivalent office) website. You'll describe exactly what's changing and the date the change takes effect, then pay a filing fee that varies by state. Most states accept the form online with card payment; some still require mail. Processing time and fee both vary significantly by state, so check the current numbers on your state's own portal rather than assuming.

If an entity has filed several amendments over time, most states allow (but don't require) filing Restated Articles of Organization or Incorporation, which consolidates every prior amendment into one clean, current document instead of leaving a trail of separate amendment filings a reader has to piece together.

If your state requires a recurring annual or biennial report, the next one you file should reflect the change. Internal documents — an LLC's operating agreement or a corporation's bylaws — aren't filed with the state, but should be updated to match, since they're not automatically corrected by the state filing. If your entity is one of the few still required to file a federal BOI report (foreign reporting companies registered to do business in a U.S. state), a name or address change may need to be reflected there too; see this site's guide on beneficial ownership information reporting for who that actually applies to today.

Do all states call it "Articles of Amendment"?

No. Most states use that name, but some use a different term for the same filing — New York calls it a Certificate of Amendment. Check your specific state's Secretary of State site for its exact form name.

Can I change my registered agent without filing a full amendment?

Often, yes. A number of states have a separate, simpler form just for a registered agent or address change, rather than routing it through the general amendment form. Confirm which form your state actually requires before filing.

Is changing my trade name (DBA) the same as filing Articles of Amendment?

No — a DBA or trade name change is a separate filing with its own requirements, typically at the county or state level depending on where you operate. Articles of Amendment only changes information on your original formation document.

Do I need a lawyer to file Articles of Amendment?

Not usually. Most states' amendment forms are straightforward enough to file directly, though a more complex change (like restructuring ownership or authorized shares) is a reasonable case for getting advice from an attorney or your accountant first.
