Adding a Member to an LLC: What Gets Filed and What Doesn't

A member who walked away from a Texas LLC in March can still be listed in the Secretary of State's management records the following spring, and the office is plain that the former member cannot correct that there directly. An individual who is not authorized to act for an entity "cannot file documents in the secretary of state's records on behalf of the entity, except in the limited circumstance of the resignation or rejection of appointment as a registered agent," its FAQ reads (Texas SOS, Management and Ownership FAQs, read 22 September 2026). The company has to update its own record, and in Texas that normally happens once a year, on the report it files with the Comptroller.

Much of the confusion about member changes starts from the wrong picture of what the state knows. People assume the Secretary of State keeps a roster, so adding or removing someone must mean filing something with it. In a large share of states the filing office never had a roster. The change is real, binding and enforceable without the state hearing about it, and it is made in a document that sits in your files. In a smaller number of states the office does hold names, and there the rules run from "update it when you get around to it" to "amend within thirty days or you cannot sue on your contracts."

The legal act and the public notice are two different steps, and people who get one right often skip the other.

Many states never had your member list

Start with what your formation document contains, because that is all the state can update. Delaware's certificate of formation has to set out three things: the name of the company, the registered office and registered agent, and "any other matters the members determine to include therein" (6 Del. C. § 18-201(a), read 22 September 2026). No member names are required. Delaware LLCs also file no annual report; the Division of Corporations says so in bold on its tax page, and what they owe instead is a flat $400 tax due on or before June 1 (Delaware Division of Corporations, LLC/LP/GP tax instructions, read 22 September 2026). A Delaware LLC can go from one member to six and back to two without any document at the state changing.

Texas holds a little more, and the difference matters. Its Secretary of State "does not maintain any information on the ownership of a LLC," but it does have "information on the initial members of a member-managed LLC," taken from the certificate of formation, and it keeps management records fed from the franchise tax filing (same Texas FAQ). So a Texas record can name people. It just does not track who owns what.

That split between management and ownership is the thing to keep in view across states. Where the state asks for names, it almost always asks for the people who run the company: the managers of a manager-managed LLC, or the members of a member-managed one, because in that structure the members are the managers. A passive investor in a manager-managed LLC often appears on no state document at all. Arizona is the exception worth knowing, covered below.

The operating agreement is where someone becomes a member

A member is admitted by the company's own rules, not by the state.

Delaware: after formation, a person who is not an assignee becomes a member "upon the consent of all members or as otherwise provided in the limited liability company agreement" (6 Del. C. § 18-301(b), read 22 September 2026). California, which follows the revised uniform act, lists the same two main doors: as provided in the operating agreement, or "with the consent of all the members" (Cal. Corp. Code § 17704.01(c), read 22 September 2026). Both statutes also say a person can become a member without contributing anything.

So if your operating agreement has an admission clause, that clause controls, including any vote threshold it sets. If it has none, or there is no written agreement, the default in both states is unanimous consent. A 60/40 LLC where the 60% member signs a new member in over the other's objection has not admitted anyone under that default.

Buying a share is not the same as joining

A common failure starts with an existing member selling part of an interest to an outsider, after which everyone assumes the buyer is now a member. Under the default rules, the buyer gets the money side and not the vote.

Delaware's § 18-702 says an assignee "shall have no right to participate in the management of the business and affairs" of the LLC unless the agreement provides otherwise or all members consent. By default the assignment entitles the assignee to share in profits, losses and distributions to the extent assigned, and "does not entitle the assignee to become or to exercise any rights or powers of a member" (6 Del. C. § 18-702, read 22 September 2026). The assignee becomes a member only as the agreement provides, or on the vote or consent of all members (§ 18-704(a)). One carve-out: when a sole member assigns the entire interest to a single assignee, that assignee becomes a member unless the agreement says otherwise (§ 18-704(a)(3)).

California reaches the same place in different words. A transfer of a transferable interest is permissible, does not by itself dissociate the transferring member, and does not entitle the transferee to "vote or otherwise participate in the management" (Cal. Corp. Code § 17705.02(a), read 22 September 2026).

In practice that means a deal usually needs two signed things, not one: the assignment of the interest, and the members' consent admitting the buyer. If only the assignment exists, you may have a transferee with a claim on distributions and no seat at the table.

Leaving on your own terms is not guaranteed

Removing a member splits into two different events: a member who wants out, and members who want someone else out. States handle the first very differently.

Delaware's default is strict. A member may resign "only at the time or upon the happening of events specified in a limited liability company agreement," and unless the agreement provides otherwise, "a member may not resign from a limited liability company prior to the dissolution and winding up" of the company (6 Del. C. § 18-603, read 22 September 2026). A Delaware member with a silent agreement who wants to leave usually has to negotiate a buyout or sell the interest, and as the section above shows, selling it does not automatically make the buyer a member.

California's default is the reverse. A person "has the power to dissociate as a member at any time, rightfully or wrongfully," by withdrawing by express will (Cal. Corp. Code § 17706.01, read 22 September 2026). Power is not the same as right. Withdrawing before the company terminates is wrongful under the statute's default, and a member who dissociates wrongfully "is liable to the limited liability company and to the other members for any damages caused by the dissociation." Dissociation takes effect when the company has notice of the member's express will to withdraw, or on a later date the member names (§ 17706.02(a)).

Pushing someone out is narrower still. Under California's default, the other members can expel a member by unanimous consent only in listed circumstances, for example when the member has transferred all of their transferable interest (§ 17706.02(d)). Otherwise expulsion runs through the operating agreement or a court order. If the plan is to remove a member who has not agreed to go, the operating agreement and a lawyer come before any form.

The filing questions below assume the change has actually happened under these rules. A state form recording a departure that the operating agreement did not permit does not make the departure valid.

Three ways a state ends up holding a member's name

Once the change is effective internally, the question becomes whether the public record has to follow, and how fast. The states sort roughly into three groups.

Mandatory amendment, on a short clock: Arizona

Arizona's articles of organization have to name each member of a member-managed LLC, or, for a manager-managed one, each manager and each member owning a twenty percent or greater interest in capital or profits (A.R.S. § 29-3201(B)(4), read 22 September 2026). The amendment statute then makes keeping those names current a duty with a date. The articles "shall be amended ... within thirty days after" a member-managed LLC "has a change in members," or a manager-managed LLC "has a change in managers or a change in members owning twenty percent or greater interest in the capital or profits of the company" (A.R.S. § 29-3202(B), read 22 September 2026).

The consequence is in subsection J, and it has nothing to do with fines. An LLC that has not amended as required "may not maintain an action on or on account of a contract or transaction made in the name of the company in any court of this state until it has amended its articles." An Arizona company that skipped the amendment for a year finds out when it tries to sue a client for an unpaid invoice.

There is one piece of relief. Arizona ordinarily requires an approved amendment to be published in a newspaper within sixty days, or, where the statutory agent's street address is in a county of more than 800,000 people, entered by the Corporation Commission in its database (subsection H). Subsection I exempts amendments that change only the names or addresses of members or managers. So a pure membership change is the filing without the publication step.

An optional update that becomes due later: California

California collects member and manager names on the Statement of Information, not in the articles. The statement lists managers and the chief executive officer or, if no manager has been appointed, "the name and business or residence address of each member" (Cal. Corp. Code § 17702.09(a)(5), read 22 September 2026). It is due within 90 days of formation and every two years after that.

What the same section says about mid-cycle changes is precise, and the wording is the useful part. When any of the required information changes, other than the agent, the LLC "may file a current statement." When the agent or the agent's address changes, the LLC "shall file" one (§ 17702.09(d)). A member change is a "may." You can leave it for the next biennial statement and be in compliance, though the public record will show the old names until then, which matters if a bank or a new partner is about to look the company up. The online form is on bizfile Online, and the Secretary of State's Statement of Information page covers the mechanics.

An annual report that catches up: Texas

Texas collects the names of the people running the company through the Public Information Report, which every LLC subject to franchise tax files with the Comptroller once a year, whether or not it owes tax (Tex. Tax Code § 171.203(a)-(b)). The Secretary of State describes how a change reaches its records: "Once a change in management has been made internally by the entity," the records "may be updated in two ways." LLCs are required to update management information each year on that report, and "although amendments are not required," an LLC may also file an amendment to update it sooner (Texas SOS FAQ, read 22 September 2026). The same page warns that the management information it holds "is not necessarily current."

That brings back the stranded former member from the top of this page. The one thing that person can file goes to the Comptroller, not the Secretary of State, and it fits a narrow case. Under Tex. Tax Code § 171.203(e) (statute text read 22 September 2026), a person named on a report who was not an officer or director of the LLC "on the date the report is filed" may file with the Comptroller "a sworn statement disclaiming the person's status as shown on the report." The Secretary of State's FAQ adds that the Comptroller forwards that information so the management records can be updated. So if next year's report still lists someone who left in March, that person has a remedy. If the stale entry comes from a report filed while they really were a member, the statement does not fit, and the fix has to come from the company. Subsection (d) also requires the LLC to send a copy of the report to each person named on it who is not currently employed by the company, which is often how a former member learns the name is still there.

Finding out which kind your state is

A fifty-state table goes stale as forms and thresholds change. The check below gives you the answer for your own state from the documents it actually holds.

  1. Pull your own filed formation document from the state's business entity search. Note every field that names a person other than the registered agent and organizer. If there are none, the state holds no member list in that document. The search is also where you confirm the company is still in good standing, which you will want before filing anything.
  2. Pull your most recent annual report, statement of information or biennial report. Same exercise. Many states put managers or members here and nowhere else.
  3. If either document names members or managers, search the state's LLC act for the words "change in members," "change in managers" and "shall be amended." A time limit, if there is one, will sit next to those words, as Arizona's thirty days do.
  4. Check the filing office's forms page for a document called a statement of change, statement of information, or amended annual report. Some states let you update names through one of these instead of a full amendment to the articles.
  5. If you are registered as a foreign LLC in other states, repeat steps 2 to 4 for each of them. Their annual reports may list managers even when your home state does not.

If every answer comes back empty, your filing obligation for a member change is zero, and the whole transaction lives in the documents described next.

The internal record is the one people forget

Because no form is due, it is easy to treat an internal change as finished once everyone agrees on a call. That leaves nothing on paper showing that the new person is a member or that the old one has left, and that record is what a bank, a lender, an acquirer or a court will ask for later.

A complete file for one member change usually holds these items:

  • The members' written consent admitting the new member, or accepting the withdrawal, signed at whatever threshold the operating agreement sets. If the agreement is silent, that means everyone.
  • The assignment or subscription document showing how the interest moved: sold by an existing member, issued by the company for a contribution, or given for services.
  • A joinder in which the incoming member agrees to be bound by the operating agreement. Without one, whether the new member is bound by the agreement's restrictions is a question you do not want to be arguing about.
  • An amended schedule of members with names, percentages, and capital contributions. Many operating agreements keep this as an exhibit precisely so it can be replaced without redrafting the whole agreement.
  • An amended operating agreement if the change alters anything else: a single-member agreement turning into a multi-member one, new voting rules, a buy-sell clause the newcomer insisted on.

Some states make part of this mandatory even when nothing is due at the filing office. California requires every LLC to keep, at its designated office, "a current list of the full name and last known business or residence address of each member and of each transferee," in alphabetical order, with each one's contribution and share of profits and losses (Cal. Corp. Code § 17701.13(d)(1), read 22 September 2026). That list has to include transferees, so the buyer from the assignment section who never became a member still goes on it. Delaware, which wants no names at the filing office, still requires an LLC to "maintain a current record that identifies the name and last known business, residence or mailing address of each member and manager" (6 Del. C. § 18-305(h)).

One practical point on single-member LLCs that gain a second member: a one-member operating agreement usually has no voting rules, no allocation of profits between members and no exit provisions, because there was nobody to allocate to. Adding a name to the schedule of such an agreement leaves the two members governed mostly by the state's default rules, which in Delaware include the rule that neither can resign before dissolution. A two-person LLC is the point at which the operating agreement actually needs rewriting.

Where the federal side comes in

The tax effects are covered in detail in when an LLC needs a new EIN, so only the parts that affect the filing checklist are here.

When a single-member LLC gains a second member, it becomes a partnership for federal tax purposes unless it has elected corporate treatment. When a two-member LLC drops to one, the partnership ends and a final Form 1065 is due for the short year. In both directions the LLC generally keeps its EIN if it already had one. How the new member came in matters more than the filing: buying an interest from an existing member and contributing money to the company are taxed differently, which is a reason to bring in a tax preparer before the documents are signed.

A separate notice applies if the person the IRS has on file as the LLC's responsible party is the one leaving. The IRS uses Form 8822-B for a change in the identity of the responsible party, and its form page states that "changes in responsible parties must be reported to the IRS within 60 days" (IRS, About Form 8822-B, page last reviewed 25 June 2026). No such notice is needed when a member who was never the responsible party joins or leaves.

Beneficial ownership reporting is the step many older checklists still include, and for a US-formed LLC it no longer applies. The domestic paragraph of the reporting company definition at 31 CFR § 1010.380(c)(1)(i) now reads "[Reserved]"; what remains covers entities formed under the law of a foreign country and registered to do business in a state (eCFR text read 22 September 2026). If your LLC was formed abroad and registered in a US state, a change in who is a beneficial owner still requires an updated report "within 30 calendar days after the date on which such change occurs," under § 1010.380(a)(2)(i), though the rule no longer asks for information about beneficial owners who are United States persons (§ 1010.380(b)(5)(i)). The 2026 rule change is covered separately.

When the departing member was also on the record for something else

The member change itself may need no filing, but the person leaving often held some other role that does. Before the departure is final, check whether they were any of these:

The registered agent. Small LLCs often name one member as agent. If that member leaves, the agent has to change, and that is not optional anywhere. California's statute, which lets member updates wait, says an LLC "shall file" a current statement when it changes agent. The steps, and the gap that opens if the old agent resigns first, are in switching registered agents without a gap.

The named manager. In a manager-managed LLC, a departing member who was also the manager is a management change, and management is exactly what most state records track. That is the item that turns a "may update" into a filing in several states.

The bank signer. Banks work from their own resolutions and signature cards, not from the state record. A departed member whose signature card is still active can still move money until the bank is told, and the bank will want the members' written consent from the internal file to act on it.

The contact on state and tax accounts. Annual report reminders, franchise tax notices and sales tax correspondence go wherever the company last told each agency to send them. If that was the departing member's email or home address, the next notice goes to someone with no reason to act on it, and a missed notice is how an LLC slides toward administrative dissolution.

The order that avoids most of these problems: sign the internal documents first, since they are the change; then do any mandatory filing in states like Arizona; then change the agent, bank and account contacts; and leave optional state updates for last, or for the next annual report if the state allows it. Do it the other way and the public record can show a change that the company's own documents do not yet support.

Frequently asked questions

Do I have to file anything with the state to add a member to my LLC?

It depends on whether your state's records name members at all. Delaware's certificate of formation asks for only the company name, the registered office and agent, and anything else the members choose to include (6 Del. C. § 18-201(a), read 22 September 2026), so an added member normally produces no Delaware filing. Arizona sits at the other end: a member-managed LLC must amend its articles within thirty days after a change in members (A.R.S. § 29-3202(B), read 22 September 2026). Many states sit in between, where members or managers show up on an annual report or statement of information and the update is optional until the next one is due. Open the document your state holds and look for a field that names people.

What actually makes someone a member of an LLC?

The operating agreement, or, if it says nothing, the consent of all existing members. Delaware lets a person who is not an assignee be admitted after formation upon the consent of all members or as otherwise provided in the LLC agreement (6 Del. C. § 18-301(b)). California lists the same routes, including with the consent of all the members (Cal. Corp. Code § 17704.01(c), read 22 September 2026). A state filing can record a member who has been admitted; it does not do the admitting.

Can a member simply quit an LLC?

Not everywhere. In Delaware, unless the LLC agreement provides otherwise, a member may not resign before the company dissolves and winds up (6 Del. C. § 18-603). California goes the other way: a person has the power to dissociate at any time, but a withdrawal can be wrongful, and a member who dissociates wrongfully is liable for the damages it causes (Cal. Corp. Code § 17706.01). Read your operating agreement first, then your state's default rule.

Does adding or removing a member mean I need a new EIN?

Usually not. The number stays with the LLC when it moves between single-member and multi-member status, although the tax return it files changes. The exception is a single-member LLC that never had its own EIN and has been running on the owner's number. If the change also replaces the person listed as responsible party with the IRS, Form 8822-B is the notice, and the IRS says changes in responsible parties must be reported within 60 days (IRS, About Form 8822-B, page last reviewed 25 June 2026).
