Buy-sell agreement for an LLC (2026)

A buy-sell agreement (buyout / transfer-restriction terms) is how multi-member LLCs plan ownership changes before a crisis — death, disability, divorce, voluntary sale, insolvency, or deadlock — instead of improvising under state default statutes. It usually lives inside the operating agreement or as an attached side deal. It is not an SOS filing, not articles of organization, and not the same as dissolving the company.

Short version for 2026: OA / default rules → counsel drafts triggers, ROFR / consent, valuation method, funding → keep with company records (do not file with SOS) → when a trigger closes, run transfer or remove-member desks, then SOS listing / bank KYC / tax with CPA as needed. Formation Lane does not invent valuation formulas, insurance products, or a “Form X in every state” buy-sell rule.

What is a buy-sell agreement for an LLC?

A buy-sell (buyout / transfer-restriction) agreement is the planning contract for membership-interest changes when a trigger hits — death, disability, divorce, voluntary sale, or other events members write in. It usually lives inside the operating agreement or as a side deal — not an SOS form, not articles, and not dissolving the company. Desk map — not a template.

1. Read the OA and formation-state default rules. Find existing transfer, consent, ROFR, buy-sell, redemption, and admission clauses. If there is no written deal, state default LLC statutes may fill gaps — confirm with counsel when stakes are real. Operating agreement basics and articles vs OA maps sit on the sibling desks linked below.
2. Have counsel draft or update buy-sell terms. Cover triggers, who may buy (company vs members vs permitted outsider), consent / ROFR, valuation method, and payment / funding mechanics. Distinguish assignee economic rights from admission as a full member when that split matters. Formation Lane does not host a template or invent valuation math.
3. Keep the signed agreement with company records. Do not mail the buy-sell to the Secretary of State. Store it with the operating agreement, membership schedules, and capital accounts. Banks may later ask for the packet when ownership changes.
4. When a trigger fires, run the execution desks. Close the assignment / redemption under the agreement, then follow Transfer LLC ownership or Remove a member from an LLC as the facts fit. Update SOS public listings when required, bank KYC, licenses / contracts, and point tax / basis questions to a CPA — not an invented national buy-sell form.

Buy-sell vs transferring ownership today vs dissolving?

Different desks. The buy-sell is the plan (triggers, who may buy, price method, ROFR / consent). Executing a sale or gift under that plan (or under default statute) is the transfer LLC ownership walkthrough. Winding up the whole entity is dissolve or cancel an LLC. Do not collapse planning, a live transfer, and dissolution into one SOS click.

Ending involvement by shutting the company down instead of selling: Close the LLC vs sell membership. Member’s-eye voluntary dissociation without a lined-up buyer: Withdraw as an LLC member.

Is a buy-sell filed with the Secretary of State?

No. Buy-sell terms are private company records — the SBA notes operating agreements stay with core business records and are not filed with the state. After a buyout closes, you may still refresh public manager/member listings on an annual report or Statement of Information when required — a separate SOS desk, not “file the buy-sell.” Map: Operating agreement vs articles.

Patterns cited from official pages (re-checked 6 October 2026) — no invented national buy-sell filing fee:

• Private OA vs public SOS. The SBA states operating agreements are kept with business records and are not filed with the state. California’s Business Entities FAQs say the same for bylaws and operating agreements. Process siblings: Operating agreement basics, Operating agreement vs articles.
• After a buyout closes — public listing when required. California’s Form LLC-2 notes that manager and related changes go on a Statement of Information (Form LLC-12), not LLC-2. Florida’s Sunbiz annual report (e-file) updates or confirms Division of Corporations records and can add, delete, or change managers and authorized members. Fee and window detail lives on LLC annual report and Transfer LLC ownership — not as a new invented “buy-sell filing” fee here.

Other formation states name their own annual report, Statement of Information, articles amendment, or mid-year change instrument. Use that state’s SOS fee schedule and the matching form-LLC guide.

What usually goes in an LLC buy-sell?

Typical building blocks (confirm with counsel): triggers (death, disability, divorce, voluntary transfer, insolvency); who may buy (company redemption, remaining members, or a permitted outsider); right of first refusal / consent; a valuation method agreed in advance; and payment / funding mechanics. Formation Lane does not invent valuation formulas, insurance products, or a national mandatory-clause list — attorney for deal docs.

Assignee as member vs economic rights only?

Many operating agreements and state default LLC statutes distinguish an assignee who receives economic rights (distributions) from a person admitted as a member with voting / governance rights. A buy-sell often controls both paths. Related: Add a member to an LLC and Transfer LLC ownership. Confirm your OA and formation-state defaults — no 50-state assignment table here.

When a trigger later fires and someone needs to be admitted as a full voting member, use Add a member to an LLC. When the path is a sale, gift, or assignment of interest under the OA, use Transfer LLC ownership. Company-side redemption / forced exit after a trigger: Remove a member from an LLC. Tax characterization of the close stays with a CPA — IRS LLC pages and Publication 3402 (re-fetched 6 October 2026) frame classification at a high level only; Formation Lane invents no tax outcomes.

After the agreement is signed

Keep the buy-sell with the operating agreement, membership schedules, and capital accounts. When a trigger later fires, continue on the matching execution guide: Transfer LLC ownership, Remove a member from an LLC, Withdraw as an LLC member, or Add a member to an LLC. If you are ending the company instead of shifting ownership, use Dissolve or cancel an LLC · Close the LLC vs sell membership. First-30-days desk list: After you form an LLC.

How does this relate to adding or removing a member?

A buy-sell often drives those paths. Bringing someone in after a sale or gift still needs admission / capital records when the OA requires it — Add a member to an LLC. A redemption or forced exit after a trigger is the remove / buyout lane — Remove a member from an LLC. Member’s-eye voluntary exit: Withdraw as an LLC member. The buy-sell page is the planning instrument; those pages are the execution maps.

What about tax when a buyout closes?

Tax characterization of a redemption vs a cross-purchase, basis, capital accounts, installment treatment, and any gift or estate facts are CPA / attorney desks. IRS LLC materials and Publication 3402 frame classification and LLC taxation at a high level — they are not a substitute for advice on your buyout. Formation Lane invents no tax outcomes, purchase-price formulas, or Form numbers for every close.

Is this page legal or tax advice?

No. Formation Lane publishes a process map: what a buy-sell usually covers, how it differs from a live transfer and from dissolution, and which sibling desks move when a trigger fires. Drafting clauses, valuing interests, funding mechanics, and tax outcomes belong to counsel and a CPA who can see your facts. Formation Lane does not draft buy-sell agreements or file SOS updates for anyone.
