To sell your share of a business, start by reading your operating agreement, partnership agreement, or shareholders’ agreement to see who you’re allowed to sell to and at what price, then negotiate terms, sign a purchase agreement matched to your entity type, and plan for the tax bill and any personal guarantees that will outlive the sale. The mechanics differ for corporation stock, an LLC membership interest, and a partnership share, but the sequence is the same, and skipping any step can leave you liable for company debts or facing a deal that gets unwound after closing.
Check What Your Governing Agreement Allows
Before you name a price or approach a buyer, pull every governance document the company has on file. Most closely held businesses include a buy-sell provision that dictates how an owner exits. A transfer that violates these rules can be voided entirely, so this is where the sale actually begins.
Buy-sell provisions come in two forms. In a cross-purchase arrangement, the remaining owners buy your interest directly. In a redemption, the company itself buys it back. The structure affects both the paperwork and the tax treatment of what you receive.
A right of first refusal clause requires you to offer your interest to existing owners before shopping it outside. If an outside buyer makes an offer, you present those terms internally, and your co-owners have a set window to match them. Only if they pass can you go through with the outside sale. Some agreements go further and set a pre-negotiated formula price for buyouts tied to specific events like death, disability, divorce, or bankruptcy.
If you hold a minority stake, look for drag-along and tag-along clauses. A drag-along lets a majority owner who is selling force you to sell alongside them on the same terms. A tag-along works in your favor, letting you join a majority sale on equal footing.
One more trap: if you live in a community property state and acquired the interest during your marriage, your spouse likely has a legal claim to it. Transferring community property without written spousal consent can make the whole transaction voidable, even if only your name appears on the operating agreement. Get the signature.
Set a Defensible Price
Three standard approaches produce a business valuation, and the right one depends on what your company actually looks like.
- The asset-based approach subtracts total liabilities from the fair market value of all assets, including intangibles like intellectual property and customer lists. It fits companies with meaningful equipment, inventory, or real estate.
- The income approach projects future earnings and discounts them to present value, typically drawing on at least three years of financial statements. It rewards companies with predictable cash flow.
- The market approach compares your business to similar companies that recently sold, using multiples like price-to-earnings or price-to-revenue. Reliable comparable data can be thin in niche industries.
Your governing agreement may cut through all of this by specifying a formula, such as book value plus a percentage of annual revenue, or by requiring an independent appraiser. Follow whatever the agreement prescribes. A seller who ignores a contractual formula and insists on a different number hands the remaining owners an easy legal argument to block the sale.
Discounts on a Minority Stake
If you own less than a controlling share, expect your price per percentage point to be lower than the owners’. A minority interest discount reflects your inability to direct company decisions or force a sale. A lack of marketability discount reflects the fact that no public exchange exists for shares in a private business. They apply one after the other. Minority interest discounts commonly run 20 to 40 percent, and marketability discounts add another 10 to 33 percent. Stacked, they can cut the value of your stake nearly in half, which surprises owners who assumed a 25 percent interest was worth exactly a quarter of the company.
Get Your Records Ready for the Buyer
A serious buyer will inspect the company’s books before committing, and the review runs deeper than most first-time sellers expect. Getting your files in order before negotiations start speeds the process and takes away the buyer’s leverage to chip at the price citing perceived risk.
Financial records lead the list: audited financials for the past three years, recent unaudited statements, federal and state tax returns (including payroll, sales, and excise), accounts receivable and payable schedules, inventory reports, and a full picture of debts and contingent liabilities. Legal records include the articles of incorporation or organization, bylaws or operating agreement, meeting minutes, a current cap table, and any options or convertible securities. Add active contracts, leases, insurance policies, intellectual property documentation, and employment agreements including non-competes and benefit plans.
What You’ll Owe in Taxes
Taxes are where sellers most often get blindsided. Not every dollar of proceeds is taxed the same, and the way the deal is structured can move real money between you and the IRS.
Capital Gains
If you held your interest for more than a year, your gain generally qualifies for long-term capital gains rates. For 2026, the rates are 0, 15, or 20 percent based on taxable income. Single filers pay nothing on long-term gains up to $49,450; the 20 percent rate begins above $545,500. For married couples filing jointly, the 20 percent threshold is $613,700. Ordinary income rates for 2026 top out at 37 percent, so the gap matters.1Internal Revenue Service. IRS Releases Tax Inflation Adjustments for Tax Year 2026
Hot Assets in a Partnership or LLC
If your business is a partnership or a multi-member LLC taxed as one, some of your gain will not be capital. Under federal tax law, the portion attributable to the entity’s unrealized receivables and inventory items is taxed as ordinary income regardless of how long you held the interest.2Internal Revenue Service. Sale of a Partnership Interest These are the Section 751 “hot assets.” The partnership must file Form 8308 to report a sale involving hot assets,3Internal Revenue Service. About Form 8308 and your final Schedule K-1 for the year will break out the ordinary income portion separately.4Internal Revenue Service. Partner’s Instructions for Schedule K-1 (Form 1065)
Net Investment Income Tax
An additional 3.8 percent tax on net investment income applies to gains from selling a business interest if you were a passive owner. It hits the lesser of your net investment income or the amount by which your modified adjusted gross income exceeds $200,000 for single filers or $250,000 for married couples filing jointly. Those thresholds are not indexed for inflation, so they reach more taxpayers each year.5Internal Revenue Service. Questions and Answers on the Net Investment Income Tax
Installment Sales
If the buyer pays you over time instead of in a lump sum, the installment method lets you spread the taxable gain across the years you actually receive money. Each payment splits into return of basis (not taxed), capital gain, and interest income, with the gain ratio held constant across payments.6eCFR. 26 CFR 15a.453-1 Spreading the income can keep you in a lower bracket year to year.
Any installment note must charge interest at or above the Applicable Federal Rate published monthly by the IRS. For March 2026, the AFR ran from about 3.6 percent on short-term notes to 4.7 percent on long-term notes.7Internal Revenue Service. Rev. Rul. 2026-6 – Applicable Federal Rates Charge less than the AFR and the IRS imputes interest at the applicable rate, meaning you owe tax on interest income you never actually collected.8Office of the Law Revision Counsel. 26 USC 1274
Qualified Small Business Stock
If you are selling stock in a C corporation, some or all of the gain may be excludable under the qualified small business stock rules. For stock acquired after July 4, 2025, you can exclude up to 100 percent of the gain if you held it at least five years, the corporation’s gross assets never exceeded $75 million, and the company was engaged in an eligible business. The maximum excludable gain per seller, per company, is $15 million or ten times your adjusted basis, whichever is greater.9Office of the Law Revision Counsel. 26 USC 1202 Professional service firms like law and accounting practices do not qualify, and the exclusion is not available for LLC or partnership interests at all.
Stock Sale Versus Asset Sale
Deal structure has its own tax weight. In a stock or equity sale, you sell your ownership interest directly and generally pay capital gains tax on the profit. In an asset sale, the company sells its underlying assets and then distributes the proceeds to owners, which can trigger two layers of tax in a C corporation. Sellers almost always prefer equity sales. Buyers prefer asset deals because they get a stepped-up basis in the acquired assets and larger depreciation deductions going forward. That tension shapes the price negotiation.
Write the Transfer Agreement
The document that actually transfers your interest goes by different names depending on entity type. Corporations use a stock purchase agreement. LLCs use a membership interest purchase agreement. Partnerships use an interest assignment agreement. The label changes; the substance is the same.
At minimum, the agreement identifies both parties by full legal name and address, states the exact percentage or number of shares being transferred, sets the purchase price, and lays out payment terms. For installment deals, attach a promissory note with the schedule, the interest rate (at or above the AFR), and consequences for missed payments.
Representations, Warranties, and Disclosures
You will make formal representations: that you own the interest free of liens, that you have authority to sell, that no undisclosed lawsuits or liabilities exist, and that the financial information you provided is accurate. These are enforceable promises. If a representation turns out to be false, the buyer can come back after closing and demand compensation under the indemnification provisions.
Disclosure schedules supplement the representations. Pending litigation, tax disputes, and unusual contract obligations get listed there. Anything disclosed is carved out of your warranty, so the buyer cannot later claim you hid it. Leaving something off the schedules that you knew about is one of the fastest paths to post-closing litigation.
Non-Compete Clauses
Buyers routinely require the departing owner to sign a non-compete as a condition of the sale. The Federal Trade Commission’s attempt to ban most non-competes was blocked by a court in August 2024 and is not currently enforceable, and even the FTC rule carved out non-competes tied to a bona fide sale of a business interest.10Federal Trade Commission. Noncompete Rule Enforceability comes down to state law, which varies widely. Most states will enforce a reasonable sale-related non-compete, but “reasonable” means limited duration, limited geography, and a limited scope of prohibited activity. Push back on overly broad language, because a court that finds the clause unreasonable may void it entirely rather than rewrite it in the buyer’s favor.
Close and Update the Records
At closing, both parties sign the transfer agreement, the buyer delivers payment (usually by wire or certified check), and any ancillary documents like the promissory note or non-compete are executed. Many parties sign in front of a notary, which adds protection against later claims of forgery or duress. Notary fees are modest, generally $2 to $25 per signature.
After closing, the company updates its own books. A corporation revises its stock ledger and cancels or reissues certificates. An LLC updates its membership records and capital account schedules. If the operating agreement or bylaws need amendment to reflect the change, that happens at the same time.
Depending on the state, the company may need to file an amendment to its articles with the secretary of state, most commonly when a member or manager named in the original formation documents is the one departing. Filing fees typically run $50 to $250.
If the departing owner was listed as the entity’s “responsible party” with the IRS, the business must file Form 8822-B within 60 days of the change. Missing the deadline does not carry its own penalty, but IRS correspondence, including deficiency notices, will keep going to the old responsible party, and penalties and interest accrue whether anyone reads those notices or not.11Internal Revenue Service. Form 8822-B A partnership or LLC taxed as a partnership also reports the ownership change on its Form 1065 and issues a final Schedule K-1 to the departing partner with the “Sale” box checked.4Internal Revenue Service. Partner’s Instructions for Schedule K-1 (Form 1065)
Liabilities That Follow You Out
Signing the papers and cashing the check does not end your exposure. Two loose ends catch departing owners more than any others.
Personal Guarantees
If you personally guaranteed any of the company’s debts, that guarantee does not go away when you sell. A personal guarantee is a separate contract between you and the lender, and selling your ownership stake to someone else does not touch it. Without a written release from the lender, you remain liable for the full guaranteed debt even though you no longer have any voice in whether the business pays it.
Before closing, contact every lender where you signed a guarantee and negotiate a release. The lender is not required to grant one, but may agree if the remaining owners offer substitute guarantees or additional collateral. Get every release in writing and attach it to the closing documents. Walking away from a business while your name is still on its loans is one of the most expensive mistakes a departing owner can make.
Indemnification Survival Periods
The representations and warranties in your transfer agreement do not last forever, but they also do not expire at closing. Most agreements include a survival clause setting the window in which the buyer can bring indemnification claims for breaches. Typical survival periods run 12 to 36 months, longer for specific categories like tax representations or fraud. Negotiate this hard. A shorter survival period is a smaller tail of risk. If the agreement is silent, the state’s default statute of limitations for breach of contract fills the gap, which can be three years or more.
