Section 751 Hot Assets on an LLC Interest Sale: The Ordinary Income Split.
A 30% member sells for $1,500,000 expecting $1,200,000 of capital gain. Section 751 hands him $420,000 of ordinary income instead, sized off the LLC's balance sheet rather than the purchase agreement. In 2026 that carve-out costs $71,400.

A minority owner of an engineering firm agrees to sell his 30% LLC interest to his two partners for $1,500,000. His outside basis is $300,000, so he pencils in $1,200,000 of long-term capital gain and budgets 20% for it. Then the closing package comes back with a number nobody raised: $420,000 of that price is ordinary income. Nothing about the deal changed. Section 751 hot assets on an LLC interest sale split one check into two characters, and neither side gets a vote.
Section 751 hot assets turn part of an LLC interest sale into ordinary income.
Section 741 is the general rule and it is one sentence: gain on the sale of a partnership interest is capital, except as provided in §751. Section 751(a) is that exception, and money received for the interest that is attributable to the partnership's unrealized receivables or inventory items is treated as realized from property that is not a capital asset. Ordinary income, at ordinary rates.
The measurement is a fiction with a precise recipe. Treas. Reg. §1.751-1(a)(2) sets your §751 income at the ordinary income that would have been allocated to you if the partnership had sold all of its property for cash at fair market value immediately before you transferred the interest. The reg then does the subtraction: whatever capital gain you would have had without §751, minus that ordinary amount, is your capital gain. Total gain never moves. Only the character does, and the character is where the 17 points live. The purchase agreement does not control that split. The balance sheet on the closing date does.
Unrealized receivables under §751(c), inventory items under §751(d).
Unrealized receivables in §751(c) means rights to payment for goods delivered or services rendered that have not yet hit income. For a cash-basis firm that is every open invoice and every unbilled hour at zero basis, usually the largest hot asset on the page. The subsection also pulls in the recapture potential under §1245 and §1250, plus §617, §1252, §1253 and §1254, measured as the gain that would be recapture if the property were sold at fair market value that day. Equipment written to zero by bonus depreciation is a hot asset equal to its whole value.
Inventory items in §751(d) is broader than the word sounds. It covers stock in trade under §1221(a)(1) and any other partnership property that would throw off gain that is neither capital nor §1231, which is where accrual-basis receivables land. There is no appreciation threshold to hide behind, either. Section 1062 of the Taxpayer Relief Act of 1997 struck the substantial appreciation requirement out of §751(a), and the 120% test survives only for disproportionate distributions under §751(b).
What is not hot matters just as much. Self-created goodwill is not, which is why a service business with a thin balance sheet still delivers mostly capital gain. Neither is §1231 gain. A building depreciated straight line generates no §1250(a) recapture, so a real estate partnership's biggest asset is usually not §751 property at all. That is a smaller win than it looks. Treas. Reg. §1.1(h)-1 looks through to the partnership's assets anyway and taxes your share as unrecaptured §1250 gain at 25% instead of 20%, and the five-, seven-, and fifteen-year property a cost segregation study broke out is §1245, all of it hot.

Tax year 2026, single filer, with other income high enough that the ordinary portion sits above the $640,600 start of the 37% bracket and the capital portion above the $545,500 start of the 20% rate, both from Rev. Proc. 2025-32. The interest was held more than a year. The seller bought his 30% several years ago for $300,000 and the LLC has no §754 election, so his outside basis exceeds his $60,000 share of inside basis; §751 is still computed on the partnership's basis, which is what makes the ordinary slice this large. The 3.8% tax under §1411 is left out because §1411(c)(4) counts gain on a partnership interest only to the extent of net gain on property that would produce net investment income if the entity sold it, and the seller materially participates. State tax excluded.
One statement you file, one form the LLC files, and a deadline that moved in 2026.
Your obligation comes first. Treas. Reg. §1.751-1(a)(3) requires a statement with your return for the year of sale showing the date, the gain or loss attributable to §751 property, and the capital gain or loss. The ordinary piece goes on Form 4797, Part II, and the capital piece runs through Form 8949 to Schedule D. You also have a deadline almost nobody meets: Treas. Reg. §1.6050K-1(d) makes the seller notify the partnership of the exchange in writing within 30 days, or by January 15 of the following year if that comes first.
The LLC then files Form 8308 with its Form 1065 and furnishes a statement to both parties by the later of January 31 of the following year or 30 days after it receives your notice. What changed this year is what that January statement must contain. T.D. 10048, published May 20, 2026, removed Treas. Reg. §1.6050K-1(c)(2) and rewrote (c)(1), so the §751(a) ordinary income in Part IV of Form 8308 no longer has to be furnished by January 31. It arrives on the Schedule K-1 instead, in box 20 under code AB. The rules finalize REG-108822-25, proposed August 19, 2025, without change, and apply to returns for tax years ending on or after May 20, 2026.
So the number that decides your April estimate arrives with a K-1 that may not be issued until September. Do not wait for it. Ask for the depreciation schedule and the receivables aging as of the closing date and run the hypothetical sale yourself.
Section 751 changes what your gain is called, not what you sold.
That distinction is worth money in two places. In Rawat v. Commissioner, No. 23-1142, decided July 23, 2024, a nonresident sold a 29.2% interest in a US LLC for $438,000,000, $6,500,000 of it inventory gain. The Tax Court taxed her as though she had sold the inventory itself, which made the gain US-source. The D.C. Circuit reversed: §751(a) recharacterizes the gain, it does not convert the deal into a sale of the underlying assets, so the gain stayed foreign-source and untaxed.
The second place is state sourcing. California's Legal Ruling 2022-02, issued July 14, 2022, takes the opposite view: it looks through to the hot assets and treats a nonresident partner's §751 income as business income California can source and tax. If you live in Texas or Nevada and are selling an interest in an LLC with California operations, price that fight into the deal. Rawat is the strongest argument on your side, and the FTB's position is not settled law.
Entity type changes the analysis. There is no §751 in a sale of S corporation stock, where character turns instead on stock sale versus asset sale, which is what an F reorganization before selling an S corp controls. A C corporation owner has other exits, including selling the company to an ESOP. The LLC seller is the one handed an ordinary income problem by his own balance sheet.
