When you sell your partnership interest, Internal Revenue Code Section 741 treats the transaction as the sale of a single capital asset, so most of your gain qualifies for long-term capital gains rates if you held the interest for more than a year. The catch is Section 751, which forces you to peel off any gain tied to the partnership’s ordinary-income assets and pay tax on that slice at your regular income rates. Several other layers can push the bill higher still. Here is how the pieces fit together for a seller.
The Default Rule Under Section 741
Section 741 sets a clean starting point: gain or loss from selling a partnership interest is gain or loss from the sale of a capital asset.1Office of the Law Revision Counsel. 26 U.S.C. 741 – Recognition and Character of Gain or Loss on Sale or Exchange Your stake is treated as one intangible property right, separate from the buildings, equipment, receivables, and inventory sitting inside the partnership. You do not have to allocate the sale price across each underlying asset the way you would if you sold a sole proprietorship. One asset, one calculation.
If you held the interest more than a year, gain taxed under Section 741 falls into the long-term capital gains brackets of 0%, 15%, or 20%, depending on your taxable income.2Internal Revenue Service. Topic No. 409, Capital Gains and Losses For 2026, the 0% rate reaches taxable income up to $49,450 for single filers and $98,900 for joint filers; the 20% rate begins above $545,500 single and $613,700 joint. Holding periods of a year or less produce short-term gain, taxed at ordinary rates.
That is the default. Section 751 and the look-through rules can reclassify part of the gain, and the calculation itself has partnership-specific traps before you ever apply a rate.
Calculating Your Gain or Loss
The formula is amount realized minus adjusted basis. Both numbers have wrinkles that catch experienced taxpayers.
Amount Realized (Don’t Forget the Debt)
Amount realized includes the cash you receive, the fair market value of any property the buyer gives you, and your share of partnership liabilities the buyer takes over. That last piece is the one sellers miss. Under Section 752, when you leave the partnership, the reduction in your share of partnership debt is treated as a deemed cash distribution.3eCFR. 26 CFR 1.752-1 – Treatment of Partnership Liabilities That deemed distribution increases your amount realized.
If a buyer pays you $200,000 in cash and assumes your $80,000 share of the partnership’s mortgage, your amount realized is $280,000, not $200,000. Ignoring the debt relief understates gain and invites IRS scrutiny. Your Schedule K-1 tells you your share of recourse and nonrecourse debt.
Selling expenses you pay directly, such as legal fees and brokerage commissions, reduce your amount realized rather than being deductible separately.4Internal Revenue Service. Sale of Partnership Interest If the partnership pays them for you, the treatment is the same.
Adjusted Basis (Your Outside Basis)
The number you subtract is your outside basis, your personal tax investment in the partnership.5Internal Revenue Service. Partner’s Outside Basis This is not the partnership’s inside basis in its own assets. You need outside basis to compute your gain.
Outside basis starts with what you contributed: cash plus the adjusted basis of any property you put in. From there it moves every year. It goes up for your share of partnership taxable income, tax-exempt income, and any increase in your share of partnership liabilities. It goes down for distributions, your share of losses and deductions, and any decrease in your share of partnership liabilities.
The partnership’s Schedule K-1 (Form 1065) reflects most of these adjustments in your capital account.6Internal Revenue Service. Partner’s Instructions for Schedule K-1 (Form 1065) (2025) Your outside basis usually differs from that capital account, though, because the K-1 capital account is calculated without regard to your share of partnership liabilities. If you sell mid-year, you also need to pick up income, losses, and distributions between the last K-1 date and the sale date. Pull these figures from the partnership before you close. Reconstructing them later is painful.
The Section 751 Carve-Out for Hot Assets
Section 751 overrides the capital gain default for any part of your gain traceable to the partnership’s ordinary-income-producing assets, informally called hot assets.7Office of the Law Revision Counsel. 26 U.S.C. 751 – Unrealized Receivables and Inventory Items The logic: if the partnership had sold those assets and passed you the profits, you would have reported ordinary income on your K-1. Selling your interest instead should not convert that income into capital gain. The rule is mandatory. There is no election out.
Two categories of hot assets apply to a sale under Section 751(a): unrealized receivables and inventory items.
Unrealized Receivables
Unrealized receivables are amounts the partnership has earned but not yet reported under its accounting method, most obviously accounts receivable of a cash-method partnership. The definition reaches further. It also captures depreciation recapture that would be triggered if the partnership sold certain property at fair market value.
Recapture under Section 1245 (equipment and personal property) and Section 1250 (real property) is treated as an unrealized receivable equal to the ordinary income the partnership would recognize if it sold that property for current fair market value.8Internal Revenue Service, Treasury. 26 CFR 1.751-1 – Unrealized Receivables and Inventory Items For partnerships that own significant depreciable property, this is often the largest hot-asset piece, and it sits silently on the balance sheet until a sale.
Inventory Items
Inventory items are defined broadly as any partnership property that would not produce capital gain or Section 1231 gain if the partnership sold it. Merchandise, raw materials, work in process, and any other asset that would generate ordinary income on disposition all qualify.
One point causes frequent errors. For a sale of a partnership interest under Section 751(a), all inventory is a hot asset regardless of appreciation. The “substantially appreciated” (120%) test you may see referenced applies only to partnership distributions under Section 751(b), not to sales. The American Jobs Creation Act of 2004 removed the appreciation requirement for sales. If the partnership holds inventory, the gain allocable to it is ordinary income on your sale, full stop.
How the Bifurcation Works
The sale splits into two hypothetical transactions. First, you are treated as having sold your proportional share of the hot assets at their fair market value. The difference between that value and your share of the partnership’s basis in those assets is your ordinary income or loss. Second, the leftover amount realized minus the leftover basis is your capital gain or loss under Section 741. The total across both pieces equals your total gain. The bifurcation changes character, not amount.
The partnership is required to give you a statement showing the fair market value and adjusted basis of all hot assets so you can run this calculation. Reporting the ordinary piece as capital gain is a reliable audit trigger.
Special Rates on Look-Through Assets
Even the portion that stays capital gain is not always taxed at 0/15/20%. A look-through rule pulls out certain assets and taxes the gain attributable to them at higher rates.
Unrecaptured Section 1250 Gain (Up to 25%)
If the partnership owns depreciable real property, the gain attributable to prior depreciation, to the extent it was not already picked up as a Section 751 unrealized receivable, is taxed at a maximum rate of 25%.9eCFR. 26 CFR 1.453-12 – Allocation of Unrecaptured Section 1250 Gain Reported on the Installment Method A partner exiting a real estate partnership will often see a slice of gain taxed at this rate for depreciation the partnership previously claimed on its buildings.
Collectibles Gain (Up to 28%)
If the partnership owns collectibles (art, antiques, precious metals, coins), the gain attributable to those assets is taxed at a maximum rate of 28%.10eCFR. 26 CFR 1.1(h)-1 – Capital Gains Look-Through Rule for Sales or Exchanges of Interests in a Partnership, S Corporation, or Trust You calculate it the same way as the hot-asset bifurcation: figure the gain that would have been allocated to you if the partnership had sold all its collectibles at fair market value right before your sale. That is your collectibles gain. The character of the underlying asset follows through to you, even if you held the partnership interest for decades.
The 3.8% Net Investment Income Tax
On top of the capital gains rate and any ordinary income tax, your gain may also be subject to the 3.8% Net Investment Income Tax. NIIT applies to individuals whose modified adjusted gross income exceeds $200,000 for single filers, $250,000 for joint filers, or $125,000 for married filing separately.11Internal Revenue Service. Topic No. 559, Net Investment Income Tax These thresholds are not indexed and have not changed since the tax took effect in 2013.
Whether NIIT reaches your gain depends on your involvement in the business. If you were a passive investor who did not materially participate in operations, the gain is generally net investment income and the 3.8% applies.12Internal Revenue Service. Questions and Answers on the Net Investment Income Tax If you materially participated, the gain is generally excluded. The characterization is made as of the time of sale, and partners who were active in some years and passive in others face a more involved analysis.
Carried Interests: Three Years, Not One
Partners in private equity, venture capital, and hedge funds face an extra rule under Section 1061. If you received your partnership interest in connection with performing services (a “carried interest” or “profits interest”), you must hold it more than three years, not just one year, for the gain to qualify as long-term capital gain.13Office of the Law Revision Counsel. 26 U.S.C. 1061 – Partnership Interests Held in Connection With Performance of Services Gain that would be long-term under the normal one-year test but falls short of three years is recharacterized as short-term and taxed at ordinary rates.
The rule targets fund managers who received their interest as compensation. It does not reach partners who acquired their interest through a capital contribution, and certain real property trade or business interests are also excluded. If you are selling a carried interest, watch the three-year clock, not the one-year clock.
Installment Sales: You Can’t Defer the Hot-Asset Tax
If the buyer pays you over several years, the installment method under Section 453 can spread the capital gain portion of the tax across those years. The hot-asset portion does not get that treatment. Gain from unrealized receivables and depreciation recapture must be recognized in full in the year of sale, regardless of how much cash you actually collected.14Internal Revenue Service. Publication 537 (2025), Installment Sales
The statute is explicit: ordinary income tied to Sections 1245 and 1250 recapture, and the portion of Section 751 gain related to those amounts, is reported entirely in the year of disposition.15Office of the Law Revision Counsel. 26 U.S.C. 453 – Installment Method Only capital gain in excess of the recapture can be deferred. Gain allocable to inventory also cannot go on the installment method.
The cash-flow result is uncomfortable. You owe ordinary income tax up front, but you may be collecting small installments over five or ten years. If your hot-asset component is large, negotiate a larger year-one payment to cover the immediate tax.
Suspended Passive Losses Come Free on Exit
If the partnership was a passive activity for you and you accumulated losses that the passive activity rules kept you from deducting, selling your entire interest unlocks them. Under Section 469(g), a fully taxable sale of your entire interest lets you deduct all previously suspended passive losses against any income, not just passive income.16Office of the Law Revision Counsel. 26 U.S.C. 469 – Passive Activity Losses and Credits Limited
The condition is that all gain or loss on the sale must be recognized; a tax-deferred exchange won’t work. Released losses first offset net income from your other passive activities, and anything left over offsets nonpassive income such as wages or active business income. Suspended passive activity tax credits, unlike losses, are not released. A partner with $100,000 of suspended losses gets to use all of it on the same return that reports the sale gain, which meaningfully reduces the net tax cost of exiting.
How to Report the Sale
Reporting means splitting the gain and putting each piece on the right form. Your inputs are the partnership’s final Schedule K-1 for your last year as a partner and the Section 751 statement the partnership is required to furnish.
The capital gain or loss goes on Form 8949, Sales and Other Dispositions of Capital Assets, which flows to Schedule D of your Form 1040.17IRS. 2025 Instructions for Form 8949 – Sales and Other Dispositions of Capital Assets Short-term or long-term placement depends on your holding period.
The ordinary income from the Section 751 bifurcation goes on Form 4797, Sales of Business Property, in Part II.18Internal Revenue Service. Form 4797 Sales of Business Property Unrecaptured Section 1250 gain and collectibles gain are computed on the Unrecaptured Section 1250 Gain Worksheet in the Schedule D instructions. Attach the partnership’s Section 751 statement to your return.
The partnership will also file Form 8308 with the IRS reporting your sale, and the IRS matches the ordinary income figure to what you report. If the numbers do not line up, expect a notice. Ask the partnership for its Section 751 statement well before your filing deadline; you need it to file, and reconstructing the hot-asset figures on your own is not a workable substitute.
