To change percentage ownership in an LLC, follow the amendment process in your operating agreement, agree on a value for the interest moving between members, sign a written amendment reflecting the new percentages, and then update your tax filings, state records, and any contracts that care who owns the company. Each step has traps, and the tax piece is where most of the money is won or lost.
Read Your Operating Agreement Before Anything Else
The operating agreement controls how ownership changes happen inside the LLC. Look for the sections on amending the agreement, admitting new members, and member withdrawals or buyouts. The agreement tells you what vote is required to approve the change, and failing to follow that process can make the entire transfer legally invalid.
Pay attention to buy-sell provisions and any right of first refusal. A right of first refusal gives existing members the chance to purchase a departing member’s interest before it can be sold to an outsider. Buy-sell provisions go further, often fixing the price formula and payment terms in advance so no one has to negotiate from scratch during a stressful exit.
If the LLC Never Adopted an Operating Agreement
State default rules fill the gap. Most states have adopted some version of the Revised Uniform Limited Liability Company Act, and the default rule in most jurisdictions is that a member can freely transfer their economic rights (the right to receive distributions), but the transferee does not automatically become a full member with voting or management rights. Becoming a full member usually requires the consent of all existing members. This is where informal transfers fall apart: a member “sells” to a friend, the remaining members refuse to grant voting rights, and the buyer ends up with nothing more than a right to distributions.
Agree on Value and the Deal Terms
Before any paperwork is drafted, the members need to agree on what the interest is actually worth. Some operating agreements lock in a valuation method, such as a formula based on revenue, book value, or a multiple of earnings. If the agreement is silent, the members either negotiate a price between themselves or hire a professional business appraiser. Getting valuation wrong creates problems in every direction: the buyer overpays, the seller leaves money on the table, or the IRS questions the transaction.
Once valuation is settled, nail down the specifics. For a buyout, that means the purchase price, whether it’s paid in a lump sum or installments, and any non-compete terms. For a new member buying in, the key term is how much capital they’re contributing and what percentage they receive. Every member also needs to agree on the effective date, because that date controls how profits and losses get split for the tax year.
Capital Interest or Profits Interest for a New Member
When bringing in a new member, the LLC has a meaningful choice. A capital interest gives the new member an immediate claim on the company’s current value; if the LLC liquidated the day after the grant, the capital interest holder would receive their proportional share of the proceeds. A profits interest only entitles the holder to a share of future growth. If the company were liquidated immediately after the grant, the profits interest holder would get nothing.
This distinction matters most for taxes. Under IRS safe-harbor rules, a profits interest granted in exchange for services is generally not taxable at the time of the grant, which makes it a useful tool for compensating key employees or new partners who are contributing expertise rather than cash. The trade-off is that accepting a profits interest converts the recipient into a partner for tax purposes, meaning they will owe self-employment tax on their share of LLC income and may lose eligibility for certain employee benefits. Revenue Procedure 93-27’s safe harbor applies as long as the interest isn’t tied to a substantially certain income stream, isn’t disposed of within two years, and isn’t a disguised capital interest.1Internal Revenue Service. Revenue Procedure 2001-43
Draft and Sign the Amendment
The core document is an amendment to the operating agreement. A well-drafted amendment includes the names of all current and any new members, the previous ownership percentages, the newly adjusted percentages (which must total 100%), the consideration exchanged, and the effective date. Every member should sign.
Beyond the amendment itself, keep a membership ledger that tracks ownership history over time: the date of each transfer, the parties, the percentages before and after, and the consideration paid. If the LLC issues membership certificates, cancel the old ones and issue updated certificates reflecting the new percentages. These records matter if the LLC is ever audited, sued, or sold.
Handle the Tax Consequences
This is the step most people underestimate, and it’s where the most expensive mistakes happen. The IRS treats a multi-member LLC as a partnership for tax purposes unless it has elected otherwise, and partnership tax rules apply to every ownership transfer.
How the Selling Member Is Taxed
When a member sells their LLC interest, any gain or loss is generally treated as a capital gain or loss under Section 741 of the Internal Revenue Code.2Office of the Law Revision Counsel. 26 USC 741 – Recognition and Character of Gain or Loss on Sale or Exchange Section 751 carves out an exception for what tax professionals call “hot assets.” If the LLC holds unrealized receivables or substantially appreciated inventory, the portion of the sale price attributable to those assets is taxed as ordinary income rather than at the lower capital gains rate.3eCFR. 26 CFR 1.751-1 – Unrealized Receivables and Inventory Items A service-based LLC with a large accounts receivable balance could see a significant chunk of the sale taxed at ordinary income rates.
If the LLC has hot assets and a member sells their interest, the LLC itself must file Form 8308 with the IRS to report the transaction, attached to the LLC’s partnership return for the year of the sale.4Internal Revenue Service. About Form 8308 – Report of a Sale or Exchange of Certain Partnership Interests Missing it won’t change anyone’s tax bill, but it can draw IRS attention.
The Section 754 Election for the Buyer
When someone buys an LLC interest, they often pay more (or less) than the proportional book value of the LLC’s underlying assets. Without a Section 754 election, the new member’s share of the LLC’s internal asset basis stays the same as the old member’s, which can create tax distortions. Filing a Section 754 election allows the LLC to adjust its internal basis in partnership property to match what the new member actually paid for their interest.5Office of the Law Revision Counsel. 26 USC 754 – Manner of Electing Optional Adjustment to Basis of Partnership Property Section 743 governs the mechanics, increasing or decreasing the basis of partnership property to reflect the difference between the transferee’s purchase price and their proportionate share of the existing basis.6Office of the Law Revision Counsel. 26 USC 743 – Special Rules Where Section 754 Election or Substantial Built-in Loss
The election is made by attaching a statement to the LLC’s partnership tax return for the year of the transfer. Once made, it applies to all future transfers and distributions unless revoked, so talk to a tax advisor before filing. For the new member, the election often saves real money by allowing them to depreciate or amortize the premium they paid.
Transfers Below Fair Market Value Can Trigger Gift Tax
Transferring an LLC interest to a family member or anyone else for less than fair market value can trigger federal gift tax. The IRS treats any transfer where full consideration isn’t received as a gift, and the difference between the fair market value and the price paid counts as a taxable gift.7Internal Revenue Service. Frequently Asked Questions on Gift Taxes For 2026, the annual gift tax exclusion is $19,000 per recipient.8Internal Revenue Service. Gifts and Inheritances Transfers above that amount eat into your lifetime exemption and require filing a gift tax return, even if no tax is ultimately owed.
K-1 Allocation for the Transfer Year
The LLC’s partnership tax return for the year of the change needs to reflect the ownership shift. Each member receives a Schedule K-1 showing their share of income, deductions, and credits for their period of ownership. The LLC can allocate income using either an interim closing of the books on the transfer date or a proration method that spreads the full year’s results across the ownership periods.
Update Government Records
State Filings
Whether you file anything with the state depends on what information your LLC’s original articles of organization included. If the articles list member names or ownership percentages, you need to file an amendment with the state agency that handles business entities, usually the Secretary of State. Amendment fees typically range from $25 to $100 depending on the state. If the articles only list a registered agent and the LLC’s name, no state filing is necessary for an internal ownership change.
IRS Form 8822-B
If the ownership change results in a new person taking over as the LLC’s “responsible party” (the individual who controls the company’s finances and is listed on the EIN application), the LLC must file Form 8822-B with the IRS within 60 days of the change.9Internal Revenue Service. About Form 8822-B – Change of Address or Responsible Party – Business Filing is mandatory for any entity with an EIN when the responsible party changes.10Internal Revenue Service. Form 8822-B – Change of Address or Responsible Party The 60-day window is easy to miss during the chaos of a transition.
FinCEN Beneficial Ownership Reporting
As of March 2025, FinCEN issued a rule exempting all U.S. companies and U.S. persons from beneficial ownership reporting requirements under the Corporate Transparency Act.11Financial Crimes Enforcement Network. FinCEN Removes Beneficial Ownership Reporting Requirements for U.S. Companies and U.S. Persons, Sets New Deadlines for Foreign Companies The Treasury Department has further stated it will not enforce penalties under the Corporate Transparency Act against U.S. citizens or domestic companies.12U.S. Department of the Treasury. Treasury Department Announces Suspension of Enforcement of Corporate Transparency Act Against U.S. Citizens and Domestic Reporting Companies Unless the rule changes again, domestic LLCs currently have no FinCEN filing obligation when ownership changes.
Notify Lenders, Landlords, and Licensing Boards
This is the step people forget, and it can have immediate financial consequences. Most commercial loan agreements include a change-of-control clause that triggers a default if ownership shifts significantly (often defined as 25% or more) without the lender’s prior written consent. SBA loans are especially strict: for 7(a) and 504 loans, ownership changes require SBA approval, particularly within the first 12 months after disbursement. Closing an ownership transfer without checking your loan documents first can put the LLC’s financing at risk.
Review any leases, vendor contracts, insurance policies, and government permits. Commercial leases frequently contain assignment or change-of-control provisions. Business insurance policies may need to be updated to reflect new members, particularly if the policy names specific individuals. If the LLC holds professional licenses, such as a PLLC for medical, legal, or accounting practices, the relevant state licensing board may require notification. Medicare providers face a separate 30-day notification deadline for changes in ownership. An hour spent inventorying every contract and license before closing is far cheaper than discovering a default notice or lapsed coverage after the fact.
A Note on Securities Law
If the ownership change involves bringing in a new outside investor who will be passive, LLC membership interests can qualify as securities under federal law, and selling them without complying with securities rules can expose the LLC and its members to serious liability. The most common route around full SEC registration is Regulation D. Rule 506(b) allows an LLC to sell interests to an unlimited number of accredited investors and up to 35 non-accredited investors, provided the LLC doesn’t use general advertising to market them.13U.S. Securities and Exchange Commission. Private Placements – Rule 506(b) This issue doesn’t come up when one existing member buys out another, because no new securities are being issued. If outside money is involved, get securities counsel in before closing.
