A membership interest assignment form is the document a member of an LLC uses to transfer their ownership interest to another person or entity. Before you fill in a single field, confirm that the LLC’s operating agreement allows the transfer and that any required consents are in hand. Get those wrong and the assignment can be void no matter how cleanly the paperwork is drafted. There is no government-issued version of this form. Most transfers use an Assignment of Membership Interest agreement that the parties or their attorneys draft, often starting from a template in the operating agreement.
Start With the Operating Agreement
The operating agreement controls nearly every aspect of how membership interests change hands. Pull it and look for three things before you draft anything.
Transfer restrictions spell out what a member can and cannot do with their interest. Some agreements flatly prohibit transfers outside the existing ownership group. Others allow them but impose conditions, such as buyer qualifications or a bar on transfers that would cost the LLC a tax classification. A transfer that violates a restriction can be treated as void if the buyer knew or should have known about it.
Consent requirements vary. Under the default rules in most states, an assignee cannot become a full member without the vote or consent of all existing members. Many operating agreements modify that default, requiring only a majority or letting a manager approve transfers alone. Whatever the agreement says, document the consent in writing before you execute the form. Oral approvals create disputes later.
A right of first refusal is common in closely held LLCs. If one applies, a member who receives a third-party offer must first offer the interest to existing members on the same terms. The other members then have a set window, often 30 days, to match. Skipping this step is one of the fastest ways to invalidate an otherwise clean transfer.
Decide What You Are Actually Transferring
Not every transfer of a membership interest makes the recipient a member of the LLC. This distinction shapes what goes on the form.
When you assign a membership interest without the other members’ consent, or without meeting the operating agreement’s admission requirements, the assignee receives only the economic rights: the right to receive distributions and allocations of income, gain, loss, and deductions the transferor would have received. The assignee gets no right to participate in management, vote, or access company records. Under the Revised Uniform Limited Liability Company Act, the transferor keeps their non-economic rights as a member even after assigning the economic interest, so two different people can hold different slices of what was once a single membership interest.
For the assignee to become a full member with voting and management rights, they need either the consent of all existing members (or whatever threshold the operating agreement specifies) or admission through a process the agreement lays out. State clearly on the form whether the parties intend to transfer only the economic interest or the full membership interest, and attach any consent.
Information to Gather Before Drafting
- Full legal names and addresses for both the transferor and the transferee. Use the exact legal name that appears in the operating agreement for the transferor. If the buyer is a trust or another entity, use the entity’s legal name.
- Description of the interest. Specify percentage, number of units, and class. If the LLC has multiple classes, such as Class A voting and Class B economic-only interests, identify which is being transferred. Something like “10% Class A Membership Interest, representing 100 Units” removes ambiguity.
- Consideration. The price or value exchanged. It can be dollars, property, services, or a combination. State the exact figure. If the interest is being gifted, say so explicitly. The IRS treats gifts and sales very differently.
- Effective date. The date rights and obligations shift. This determines who receives distributions for a given period and drives tax reporting for both parties.
- The operating agreement’s transfer, consent, and right-of-first-refusal provisions, so you can confirm the form’s terms align with what the agreement requires.
What the Assignment Document Should Contain
Beyond the identification and description fields, a workable assignment includes several standard components.
Assignment and Acceptance
The assignment clause is the core, where the transferor conveys their rights, title, and interest in the specified membership interest to the transferee. Immediately after, an acceptance clause should state that the transferee accepts the assignment and agrees to be bound by all terms of the operating agreement. Without acceptance, the transferee has no contractual obligation to follow the agreement’s rules.
Representations and Warranties
Both parties should make representations. The transferor typically represents that they own the interest free of liens and encumbrances, have authority to make the transfer, and have complied with the operating agreement’s procedures. The transferee typically represents that they are acquiring the interest for their own account and not for resale, understand the interest is not registered as a security, and can bear the economic risk. These are standard in filed SEC examples of membership interest assignments.
Restrictive Legend
If the LLC has issued membership certificates, the certificate should carry a legend noting the interest cannot be resold without either registration under federal and state securities laws or an available exemption. This puts any future buyer on notice. Even without physical certificates, the assignment should reference the transfer restrictions in the operating agreement.
Indemnification
Most well-drafted assignments include a clause where the transferee agrees to hold the transferor harmless from any liabilities arising under the operating agreement after the effective date. That allocates post-transfer risk to the person who actually holds the interest going forward.
Signing the Form
Both the transferor and transferee must sign. Whether you need a notary depends on the operating agreement and state law. There is no blanket federal notarization requirement for LLC interest transfers. If the agreement calls for it, get it notarized. If it doesn’t, notarization still adds authentication that helps if the transfer is later challenged. Notary fees are modest, generally a few dollars up to $25 depending on the state.
Some operating agreements require additional signatures. The LLC’s manager or managing member may need to sign an acknowledgment that the company has received notice of the transfer. Others require a majority or unanimous vote of the remaining members, documented as a written consent or resolution attached to the assignment.
Spousal Consent in Community Property States
If the transferring member lives in Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, or Wisconsin, the membership interest may be community property. The member’s spouse then has a legal interest in the asset, and the transfer can be challenged without their consent. Get the spouse’s written consent on the form or as a separate attachment, and include an acknowledgment that the spouse had the opportunity to consult independent counsel. Alaska allows couples to opt into community property treatment by agreement, so check whether that applies as well.
Delivering the Form and Updating Records
Once everyone has signed, deliver the executed original to the LLC’s manager or registered agent. The LLC does not have to give effect to the transferee’s rights until it has actual notice, so prompt delivery matters. Until the company knows about the change, distributions and communications will keep going to the old member.
The manager should update the member ledger, the internal list showing each owner and their percentage or units, right away. That ledger drives tax reporting. Each member’s share of income, losses, and credits flows through Schedule K-1 (Form 1065), so an inaccurate ledger produces inaccurate K-1s and potential IRS problems for everyone.
Store the original executed assignment in the company’s minute book alongside the operating agreement, formation documents, and any prior transfer records. This paper trail matters during audits, financing due diligence, and potential company sales. If the membership change also alters the management structure, for example when the departing member was the sole manager, amend the operating agreement to reflect the new arrangement.
In most states, transferring a membership interest is an internal matter that does not require any filing with the Secretary of State. States generally do not track LLC ownership the way they track officers or registered agents. If the transfer changes information that does appear in the articles of organization, such as a member-managed LLC where the articles list the members, you may need to file an amendment, with fees varying by state.
Tax Follow-Through
The tax side is more complicated than most people expect for LLCs taxed as partnerships, which is the default for multi-member LLCs. Both sides need to plan for it.
Gain or loss on the sale of a partnership interest is generally treated as capital gain or loss.1Office of the Law Revision Counsel. 26 USC 741 – Recognition and Character of Gain or Loss on Sale or Exchange Any portion attributable to the partnership’s unrealized receivables and inventory items, however, is treated as ordinary income.2Office of the Law Revision Counsel. 26 USC 751 – Unrealized Receivables and Inventory Items The seller needs to know their adjusted basis in the interest to calculate the result. Basis starts with the original capital contribution and moves with the member’s share of income, additional contributions, assumed liabilities, distributions, losses, and nondeductible expenses. The seller must notify the partnership in writing within 30 days of the transaction if it holds unrealized receivables or inventory items, and must file a statement with their return for the year of the sale.3Internal Revenue Service. Publication 541 – Partnerships
The buyer’s basis in the acquired interest equals the purchase price plus any share of partnership liabilities assumed. The LLC can file a Section 754 election to adjust the inside basis of partnership assets for the new member, which avoids taxing the new member on income allocated from appreciated assets they already paid for through the purchase price. Once made, the election applies to all future transfers and cannot be revoked without IRS permission.4Internal Revenue Service. FAQs for Internal Revenue Code (IRC) Sec. 754 Election and Revocation
The LLC itself has reporting duties. If the partnership holds any unrealized receivables or inventory items when the interest changes hands, it must file Form 8308 as an attachment to its Form 1065 for the tax year that includes the calendar year of the exchange, and furnish copies to the transferor and transferee.5Internal Revenue Service. Instructions for Form 8308 (Rev. November 2025) For mid-year transfers, the LLC allocates income and other items between the departing and incoming member; the operating agreement often specifies the method, and each member receives a K-1 reflecting only their share for the period they held the interest.6Internal Revenue Service. Instructions for Form 1065 (2025)
Securities Law and Why the Buyer’s Representations Matter
LLC membership interests can qualify as securities under federal law. The classic test asks whether the arrangement involves an investment of money in a common enterprise where profits are expected to come primarily from the efforts of others, which describes a passive investor in a manager-run LLC. When an interest is a security, transferring it without registration or an available exemption violates federal and state law.
Most private transfers rely on exemptions, most commonly the private placement exemption. That is why the assignment includes the buyer’s representations about investment intent, understanding the interest is unregistered, and ability to bear the risk, and why any certificate carries a restrictive legend. These clauses protect the company and its other members from liability if the buyer later tries to resell in a way that violates securities laws.
FinCEN Beneficial Ownership Reporting
As of March 2025, FinCEN’s interim final rule exempts all entities created in the United States from the requirement to report beneficial ownership information.7FinCEN.gov. FinCEN Removes Beneficial Ownership Reporting Requirements for US Companies and US Persons Domestic LLCs no longer need to file or update BOI reports when membership interests change hands. The reporting obligation now applies only to entities formed under foreign law that have registered to do business in a U.S. state or tribal jurisdiction.8FinCEN.gov.
