Sale of Partnership Interest: Section 751, Rates, and Reporting

When you sell a partnership interest, the tax treatment splits your gain into two pieces: an ordinary-income slice tied to the partnership’s “hot assets” and a capital-gain remainder that usually qualifies for long-term rates. The ordinary piece can be taxed at rates up to 37% for 2026, while the capital piece runs at 0%, 15%, or 20% depending on your income, with a 3.8% surtax and two special rate buckets that may apply on top. Getting the number right means tracing both your own investment in the interest and the partnership’s internal asset values.

Figuring Your Gain or Loss

The formula is amount realized minus adjusted basis. Both sides have quirks worth understanding before you plug in numbers.

Amount Realized Includes Debt Relief

Your amount realized is not just what the buyer pays you. Under Section 752, any reduction in your share of partnership liabilities counts as a deemed cash distribution and gets added to the purchase price.¹ If a buyer hands you $100,000 in cash and the sale relieves you of a $50,000 share of partnership debt, your amount realized is $150,000. Sellers in leveraged real estate or private equity partnerships often discover a much larger taxable gain than expected once debt relief is folded in.

Your Outside Basis

Your adjusted basis in the interest, called your outside basis, starts with what you paid or contributed. It goes up with additional contributions and your cumulative share of partnership income, and down with distributions and your cumulative share of losses. Your share of partnership liabilities is also part of outside basis, which is why the debt drop on the sale date washes against the debt bump in your amount realized.

Before running the gain formula, account for your share of partnership income or loss from the start of the tax year through the sale date. If the partnership earned $10,000 in profit while you still held the interest, your basis goes up by your share of that profit first. That step keeps you from being taxed twice on the same dollars — once through the K-1 and again through the sale.

Holding Period

If you held the interest more than one year, the capital portion is long-term. If you built the interest through multiple contributions or purchases, you may have a split holding period, and the regulations allocate each portion based on its fair market value at acquisition.² So part of your gain can be long-term while another part is short-term. A capital asset you contributed years earlier hands its long holding period to the piece of your interest traceable to it; the cash you added later starts a new clock.

How Section 751 Carves Out Ordinary Income

Section 741 gives you the default: gain from selling a partnership interest is capital.³ Section 751 then pulls the ordinary-income piece back out before the default applies.⁴ The policy is simple: Congress did not want partners converting ordinary income into capital gain just by selling the wrapper rather than waiting for the partnership to sell its assets.

The assets Section 751 targets are called hot assets, and they come in two categories.

Unrealized Receivables

The label is misleading. Unrealized receivables sweep in far more than unpaid invoices. The definition captures any depreciation recapture built into partnership property. Equipment with Section 1245 recapture, real property with Section 1250 recapture, prior Section 1231 losses subject to the five-year lookback, and mining property all get pulled in.⁵ The practical effect is that nearly every dollar of built-in ordinary income inside the partnership comes out when you sell.

Inventory Items

Inventory items include goods held for sale plus any other property that would generate ordinary income if the partnership sold it directly. There is no “substantially appreciated” threshold on a sale of an interest — even modest appreciation triggers ordinary treatment on your share.

A Worked Example

Say your total gain is $80,000. The partnership calculates that your share of the built-in gain on hot assets is $30,000. That $30,000 is taxed as ordinary income. The remaining $50,000 is capital gain, long-term if you held the interest more than a year. You end up reporting what amounts to two transactions: one ordinary, one capital. The partnership supplies the internal data that lets you make the split.

The Rates That Actually Apply

Depending on what the partnership owns and your income, your gain can be taxed at as many as five different rates. A sale that looks like a 20% capital gains event on the surface can carry a much higher blended rate.

Ordinary Rates on Hot Assets

The Section 751 portion is taxed at your regular marginal rate, reaching 37% for 2026 for single filers with taxable income above $640,600 (or $768,700 for married couples filing jointly).⁶ A partnership with significant depreciation recapture or receivables can push this piece well past half of your total gain.

Long-Term Capital Gains Rates

The capital portion is taxed at 0% on 2026 taxable income up to $49,450 for single filers ($98,900 joint), 15% above that, and 20% once taxable income exceeds $545,500 single ($613,700 joint).⁶

The 25% and 28% Buckets

Two extra rate categories can apply. Your share of gain attributable to previously claimed straight-line depreciation on partnership real property is taxed at a maximum 25% (unrecaptured Section 1250 gain). Your share of appreciation on partnership collectibles like artwork or precious metals is taxed at a maximum 28%.⁷ Both sit between ordinary and standard long-term capital gains rates, and they apply before the remainder qualifies for 15% or 20%.

The 3.8% Net Investment Income Tax

On top of the rates above, a 3.8% surtax on net investment income may apply if your modified adjusted gross income exceeds $250,000 joint or $200,000 single.⁸ For a partnership interest sale, the surtax applies to the portion of gain that would have been net investment income had the partnership sold all its assets at fair market value right before your sale. Gain from a passive partnership activity is almost always subject to the surtax. Gain from a partnership in which you materially participated is generally exempt, though the portion tied to assets not used in the active trade or business can still be caught.

Installment Sales Do Not Defer the Hot-Asset Piece

If the buyer pays you over several years, you might expect to spread the gain out. The capital portion works that way. The Section 751 ordinary income does not. Courts and the IRS treat unrealized receivables and inventory as ineligible for installment reporting, so you owe tax on the full hot-asset gain in year one even if you haven’t collected most of the purchase price. That creates a real cash-flow problem: tax on income the buyer owes you but hasn’t paid. If an installment sale is on the table, model the Section 751 portion separately so you know how much cash you need at closing.

Suspended passive activity losses on an installment sale come out proportionally. Each year, you deduct the fraction of your suspended losses that matches the fraction of total gain recognized that year.⁹

Selling Releases Suspended Passive Losses

Partners in passive activities often have years of suspended losses piled up — losses the partnership reported that you couldn’t deduct because of the passive activity rules. Selling your entire interest in a fully taxable transaction to an unrelated buyer frees all of them at once. Under Section 469(g), the released losses first offset any gain from the sale, then offset income from other passive activities, and any excess becomes a nonpassive loss you can use against wages, business income, or other ordinary income.⁹

You must dispose of your entire interest, and the transaction must be fully taxable. A sale to a related party under Section 267 or Section 707 does not release the losses until that buyer resells to someone unrelated. A gift, a like-kind exchange, or a contribution to another entity does not qualify either. If you die holding the interest, the losses are deductible only to the extent they exceed the step-up in basis the heir receives.

How You Report the Sale

The capital gain or loss portion goes on Schedule D of your Form 1040.⁷ The ordinary-income portion from hot assets goes on Form 4797, Part II.¹⁰ Any unrecaptured Section 1250 gain or collectibles gain flows through specific lines on the Schedule D worksheet. Keep the partnership’s hot-asset allocation in your files; the IRS can ask for it years later.

The partnership has its own filings. It must attach Form 8308 to its Form 1065 for the year of the sale to report the Section 751 exchange, and send a copy to both the seller and the buyer.¹¹ It also issues you a final Schedule K-1 reflecting your share of income, deductions, and credits through the sale date.¹² The partnership either prorates the annual income or does an interim closing of the books to determine your share.

A Note on Section 754 and Buyer Negotiations

Section 754 is primarily the buyer’s issue: it lets the partnership adjust the inside basis of its assets to match the buyer’s purchase price, giving the buyer higher depreciation and lower future gain. It doesn’t change your tax bill as the seller. But it can change your price. A buyer who can’t get a 754 election in place may discount their offer to compensate for the lost tax shield, so expect the election to come up in negotiation even though the tax consequences of the election itself sit on the other side of the table.

If You Are a Foreign Seller

If you are not a U.S. person, the buyer must withhold 10% of your total amount realized — not 10% of the gain, the entire purchase price including debt relief. Section 1446(f) triggers this whenever any portion of the gain would be effectively connected with a U.S. trade or business.¹³ On a $500,000 sale with $200,000 of debt relief, the amount realized is $700,000 and withholding is $70,000. If the buyer fails to withhold, the partnership itself must deduct the missing amount plus interest from future distributions to the buyer, so proper certification at closing matters. Narrow exceptions exist for certain publicly traded partnership interests and where the seller documents that no effectively connected gain results, but the mechanics typically call for tax counsel.
