How to Change Your LLC Name: What to File and Who to Tell

A certificate of amendment can come back approved from the formation state in two business days, and that approval travels nowhere. Texas puts the sharpest version of the consequence in statute: a foreign entity already registered there that takes a name it could not have registered under has its Texas registration suspended. Nothing has lapsed. No fee is late. The name is simply already taken on that state's index - and the filing that set it off happened in a different state.

That is the shape of this job. The amendment at the formation state is a one-page form and a small fee, and it is the part everybody plans for. The work sits downstream of it, in the offices that hold a record of the company under the old name and have their own rules about what a name is allowed to be.

The name has to be available in every state that already knows you

The test is not whether the new name sounds different from somebody else's. It is whether the name is distinguishable on that filing office's own index, and the index is per-state. Delaware phrases the requirement the way most acts do: the name "must be such as to distinguish it upon the records in the office of the Secretary of State" from every corporation, partnership, statutory trust and limited liability company already reserved, formed, or qualified there (6 Del. C. § 18-102(3), read 14 September 2026). Two states can reach opposite answers on the same name without either being wrong.

Texas spells out what happens when they disagree. If a registered foreign entity "changes its name to a name that would cause the entity to be denied an application for registration," the statute does not ask it to try again. The registration "must be suspended," and the entity may transact business in Texas only after it changes the name to one available there or otherwise complies (Tex. Bus. Orgs. Code § 9.010, read 14 September 2026). One filing in your home state is enough to set that off.

So the search order runs backwards from what feels natural. Before you file anything, put the proposed name through the business entity search at every state where you hold a registration, not only the one where the company was formed. Four registrations means four searches, and any one of them can veto the name. Most states put that search online at no charge, and each one takes a few minutes.

Where a name is close but not identical, the filing office is the only party whose opinion counts. Most will answer a preliminary availability question by phone or through a name reservation request. A reservation costs a small fee and holds the name for a fixed window, which helps when the amendment has to wait on a member vote or a launch date, and helps not at all if you file the reservation in the wrong state.

The home-state filing is short, and its trigger is a duty rather than a date

The document is a certificate of amendment in some states and articles of amendment in others, and it does one thing: it changes the text of the formation document on file. Delaware's version has to set out exactly two items, the name of the limited liability company and the amendment itself (6 Del. C. § 18-202(a), read 14 September 2026). Whatever your state calls it, search its forms page for the word amendment rather than the word change, and check whether your state folds simple changes into the annual report instead of taking a standalone filing. A few do, which bolts the timing of your rebrand to your report cycle.

There is no deadline in the ordinary sense, and that is worth sitting with rather than skipping. Delaware puts the obligation on a person: a manager, or any member if there is no manager, who becomes aware that a statement in the certificate of formation "has changed making the certificate of formation false in any material respect, shall promptly amend" it (§ 18-202(b)). Promptly is not a date you can put on a calendar. It is a standard read backwards, later, by somebody who is unhappy with you.

Effective timing runs the other way and is precise. An amendment takes effect when it is filed unless the document names a later date or time (§ 18-202(d)). If the rebrand has a launch day and you want the legal name to line up with it, that delayed effective date is the mechanism. It also means the state's public record shows the old name until then, which matters if a bank or a client happens to check the index that week.

Order two certified copies of the filed amendment at the same time you place the filing, not afterwards. Nearly every office downstream asks to see it, several want a certified copy rather than a printout, and ordering them one at a time is what stretches a two-week job into a two-month one. Of everything on this page it is the cheapest step to get right and the most tedious to repair late.

Every out-of-state registration is its own filing on its own clock

A foreign registration is a separate record in a separate office, and it does not update itself when the home state approves an amendment. Delaware requires a foreign LLC whose application has become false in any respect to "promptly file" a correcting certificate (6 Del. C. § 18-905, read 14 September 2026) - the same open-ended standard as the domestic amendment.

Other states put a number on it. Texas requires a foreign filing entity to amend its registration to reflect a change to its name, and that amendment "must be filed on or before the 91st day following the date of the change" (Tex. Bus. Orgs. Code § 9.009, read 14 September 2026). Ninety-one days sounds generous until you notice where the clock starts. It starts at the home-state filing, not at the point you get around to the second state, and some states want a current certificate of good standing from the home state attached to the amendment - a document with a short shelf life of its own.

When the new name is unavailable in a state where you are already registered, there is a route that does not require giving up the rebrand. Registration statutes generally let a foreign entity register under a different name in that state. Delaware's application asks for "the name of the foreign limited liability company and, if different, the name under which it proposes to register and do business" there (§ 18-902(1)a). On a registration that already exists, the correcting or amending certificate is what carries that second name onto the record. You end up legally named one thing and registered in that state as another. It is administratively ugly and completely ordinary. It is also a close cousin of the assumed name filings you may already be running, so ask whether your state routes both through the same office.

The IRS chart has no row for an LLC

Open the IRS page on business name changes and you get a table with three rows: sole proprietorship, corporation, partnership. There is no LLC row. That is not an oversight. The IRS sorts by how an entity is taxed, and an LLC is taxed as one of those three things, so you read the row matching your classification instead of hunting for your entity type.

A partnership-classified LLC marks the name change box on Form 1065, page 1, line G, box 3. A corporation-classified LLC marks Form 1120, page 1, line E, box 3; an S corporation marks Form 1120-S, page 1, line H, box 2. A single-member LLC that never elected corporate treatment files no entity return, so it has no box to mark, and the sole proprietorship row is the one that fits: write to the address where you file, signed by the owner. If the current year's return has already gone in, every category collapses into that same written notice (IRS, Business name change, page last reviewed 22 February 2026).

Two details on that page are easy to read straight past. If the EIN was assigned recently and filing liability has not yet been determined, the notice goes to the address where you file your return rather than anywhere else. And the IRS will send an acknowledgement of the name change if you ask for one - it does not volunteer it. Ask. A bank stalling on an account update will accept that letter when it will not accept your copy of the state amendment.

The number itself does not move. The IRS says you don't need a new EIN if you just change your business name or address, and repeats the point in the LLC-specific block on the same page (IRS, When to get a new EIN, read 14 September 2026). Anyone telling you otherwise is thinking of a structural change, and the line between the two is the whole of that separate question.

FinCEN came off this list in August, unless you were formed abroad

Compliance checklists written before 2025 put a beneficial ownership update on this page, due thirty days after the name change. For a US-formed LLC that step no longer exists. FinCEN's final rule was published and took effect on 14 August 2026, adopting the narrowed scope of the March 2025 interim rule (Beneficial Ownership Information Reporting Requirement Revision, document 2026-16576). Read the regulation itself and the change is visible at a glance: the domestic subparagraph at 31 CFR § 1010.380(c)(1)(i) now says only "[Reserved]", and the definition that survives covers entities formed under the law of a foreign country and registered to do business in a state (eCFR text read 14 September 2026).

If your LLC was organized abroad and qualified into a US state, none of that relief reaches you. The name is required information, so changing it starts the updated report clock: within 30 calendar days after the date on which the change occurs, under § 1010.380(a)(2)(i). Thirty days from the amendment, not thirty days from when you remember.

Downstream, almost all of it is somebody's internal policy

Most of what follows is not governed by a statute you can look up. It is somebody's internal policy, which means the answer varies by institution and the only question worth asking is the direct one: what do you need from me to change the name on this account? One item on the list is the exception, and it is the one with money attached.

The bank goes first, because most of the rest wait on it. Expect a certified copy of the amendment, a fresh resolution or written consent naming who is authorized to sign, and new signature cards. Some banks treat a rename as a maintenance change and some open a new account number, which is a materially different amount of work - if it is the second one, every automatic debit and every client's payment instruction moves with it. Banks also sometimes re-run the beneficial ownership certification here, even though the customer due diligence rule ties that step to identifying beneficial owners "at the time a new account is opened" rather than to a rename (31 CFR 1010.230(b)(1), eCFR text read 14 September 2026).

Then, roughly in this order:

• State tax accounts - sales tax permit, employer withholding, unemployment insurance. Separate registrations, often at two different agencies, and the permit you post on the wall is usually reissued rather than corrected.
• Licenses and permits - state, county, city, and any industry board. Ask each issuing office whether a name change is an amendment or a fresh application, because those two answers cost very different amounts.
• Insurance - the named insured on every policy, including the general liability coverage a client's contract requires you to carry under a specific name. A certificate of insurance that does not match the contract gets bounced by the same accounts payable clerk who bounces mismatched W-9s.
• Payroll and merchant processing - both hold a legal name that has to match IRS records, and a mismatch surfaces as a failed tax filing months later rather than as an error on the day.
• Clients and vendors - a new Form W-9 into every vendor file, and a replacement to anyone already holding the old one for the year.

Your registered agent belongs on the same list for a duller reason: the service holds your company name on its own record and the state's agent-of-record entry has to match it, so if you happen to be switching agents in the same season, file the two changes separately and let the first one clear before the second goes in. The domain, the email addresses, the invoice template and the contract template cost almost nothing to update and are the ones clients actually notice, which is a strange way for a list to end and an accurate one.

Then there is the item with money attached. If a UCC-1 financing statement names the debtor by the old name, the change can make that filing seriously misleading, and Article 9 answers with a clock rather than with an outright loss of perfection. The statement stays effective for collateral the debtor acquired before, or within four months after, it became seriously misleading; it stops being effective for collateral acquired after that window unless an amendment curing the problem is filed inside the same four months (6 Del. C. § 9-507(c), read 14 September 2026, in the uniform wording the states have adopted in nearly identical terms). Filing that amendment is the secured party's move rather than yours. What is yours is telling the lender the effective date in writing early enough that four months is a comfortable number instead of a tight one.

An order of operations that removes most of the rework

1. Search the proposed name in every state where you hold a registration. Reserve it where the timing is tight.
2. Run a trademark clearance search if the name is a brand rather than a label.
3. Approve the change internally the way your operating agreement requires, and write down that you did.
4. File the amendment at the formation state. Order two certified copies with it.
5. Amend each foreign registration, nearest deadline first. Texas gives 91 days; several states say only promptly.
6. Notify the IRS - the box on the return where there is one, a signed letter where there is not, and ask for the acknowledgement.
7. Bank, then state tax accounts, then licenses, then insurance, then everyone who pays you.
8. Tell any secured lender the effective date in writing the same week. Their four-month window runs whether or not anybody raises it.
9. File an assumed name registration for the old name anywhere you still use it.

Steps one and four are the only two that are hard to undo. Everything after step four is slow rather than risky, and it parallelizes across as many people as you have.

What the amendment leaves exactly where it was

The entity does not change. Same company, same formation date, same EIN, same registrations, same history. That is what separates a rename from a conversion out of a sole proprietorship, where a genuinely new legal person appears and live contracts have to be assigned to it. A contract signed under the old name was signed by the same legal person that now carries the new one, which is why counterparties generally ask for a side letter acknowledging the change instead of a fresh agreement. Read the notice clause in anything large before you decide that is all it needs, because some of them put a deadline on telling the other side that your name has moved.

The filing also does not give you rights in the name. A state office runs an availability check against its own index and nothing more. Trademark rights come from use and, if you register them, from the federal register at the USPTO - a separate system that will happily let a company two states over keep using a name your Secretary of State just approved. If the new name is the point of the rebrand rather than a label, the clearance search belongs before the amendment.

And the old name goes back on the shelf. Once the amendment is effective the index no longer shows it as yours, and nothing stops the next applicant from taking it. If it still appears on signage, on a domain, on invoices, or in a contract you expect to renew, register it as an assumed name in the states where you use it before you release the legal claim to it.

One thing is worth repeating on the way out, because it is the only mistake on this page that costs money rather than time. Search the name in every state that holds a registration for you before you file the amendment, not after. That single reordering is the whole difference between a clean two-day approval and a suspension notice out of a state you were not thinking about at all.

Delaware and Texas carry most of the citations on this page because both write these mechanisms down in unusually plain language, not because your state copies them. Everything above was read on 14 September 2026. Check each figure against your own filing office before you rely on it - the shape of the requirement tends to survive from state to state, the windows and the fees do not. None of this is legal or tax advice, and the author is neither an attorney nor an accountant. Where the rename touches a lender, a lease, a license with a renewal date or a contract with a notice clause, have it priced by somebody licensed in the relevant state before the amendment goes in rather than after.
