Tax treatment of carried interest: current state of play

Carried interest is structured as a partnership profits interest rather than as a fee. Because a profits interest carries no right to existing partnership capital at grant, its receipt for services is generally not a taxable event, and the holder's return is a distributive share of partnership income that retains that income's character as it flows through. That flow-through of character is the whole mechanism; everything else in this area is a qualification of it.

The line between a profits interest and a capital interest is drawn by a hypothetical test. A capital interest would give its holder a share of proceeds on a hypothetical sale of all partnership assets at fair market value followed by complete liquidation, tested at receipt. A profits interest is any interest that is not — zero liquidation value at grant, entitling the holder only to future profits and appreciation above a threshold. Receipt of a capital interest for services produces ordinary compensation income equal to fair market value; receipt of a qualifying profits interest does not.

One anti-abuse provision sits underneath the base case and is easy to miss on a sale rather than a distribution. The hot-asset rules treat the portion of the amount realised on a sale or exchange of a partnership interest attributable to unrealised receivables and inventory items as ordinary income, with a look-through for tiered partnerships. A sale of carry can therefore produce ordinary income under those rules and short-term capital gain under the three-year overlay at the same time, from different parts of the same transaction.

Section 1061 recharacterises as short-term capital gain the portion of a partner's net long-term capital gain allocable to an applicable partnership interest that would not be long-term if a three-year holding period applied. The computation is stated in the statute as a subtraction: net long-term capital gain computed normally, minus the same computation substituting three years for one year, with the excess treated as short-term. It was enacted in December 2017 and applies to taxable years beginning after 31 December 2017.

An applicable partnership interest is any partnership interest transferred to or held by the taxpayer, directly or indirectly, in connection with the performance of substantial services by the taxpayer or a related person in an applicable trade or business. Under the final regulations, once an interest is an applicable partnership interest it remains one unless an enumerated exception applies — status survives retirement and survives the cessation of services.

An applicable trade or business is an activity conducted on a regular, continuous and substantial basis consisting in whole or part of raising or returning capital and, additionally, either investing in or disposing of specified assets, identifying specified assets for such investing or disposition, or developing them. The final regulations implement this as a test requiring both categories of action, tested cumulatively, and expressly permit the actions to be performed by related persons or agents in different entities and different taxable years. The practical consequence is direct: separating capital-raising into a different entity from the investment team does not defeat the status.

Two boundaries are worth stating with the same precision as the rule. The corporate exception removes interests held by C corporations from applicable-partnership-interest status, but S corporations and passive foreign investment companies with a qualified electing fund election are carved out of that exception and remain inside the rule. And on applicability dates, the regulation's own text governs: the provisions apply to taxable years of owner taxpayers and passthrough entities beginning on or after 19 January 2021, with an election available to apply them to a taxable year beginning after 31 December 2017 if applied in their entirety and consistently.

The exclusion list is where most of the planning value sits, and it is regulatory rather than inferred. Excluded from both the one-year and three-year distributive share amounts are gain and loss under the trade-or-business property rules, gain and loss under the section 1256 mark-to-market regime, qualified dividend income, gain or loss characterised as long-term or short-term without regard to the ordinary holding period rules including certain mixed straddles, capital interest gains and losses, and amounts otherwise excluded by the regulations.

The first of those is the one that changes real outcomes. Trade-or-business property gain is expressly excluded from the computation, so a promote characterised as such gain sits outside the three-year rule even though it is long-term — which is why the character question in a real-asset structure is worth more attention than the holding period question. Note that the anti-avoidance look-through rule does not carve out that category, so the two rules interact and should be read together rather than separately.

The capital interest exception excludes gain and loss allocated with respect to a partner's invested capital, and the regulatory conditions are specific: allocations based on relative capital account balances, determined and calculated in a similar manner to allocations to unrelated non-service partners, with rights reasonably consistent with those partners' rights as to amount, timing, rate of return, type and level of risk, and liquidation and distribution rights; unrelated non-service partners holding five per cent or more of aggregate contributed capital when the allocations are made; and the partnership agreement and books clearly demonstrating compliance separately from applicable-partnership-interest allocations. The final regulations relaxed a proposed same-manner standard to similar manner, permit investment-by-investment and class-by-class testing, and confirm that subordination, the absence of a management fee, and tax-distribution advances do not by themselves disqualify.

Two further boundaries close the section. The overlay produces short-term capital gain rather than ordinary income and imposes no self-employment tax. And the related-person transfer rule is narrower than its reputation: as finalised, a transfer means a sale or exchange in which gain is recognised, so gifts and tax-free contributions are not triggering events — the interest simply remains an applicable partnership interest in the transferee's hands. That is why transferring carry for estate-planning purposes does not force recognition.

Self-employment tax on carry is the most unsettled area in this taxonomy. The statutory exclusion covers the distributive share of any item of income or loss of a limited partner, as such, other than guaranteed payments. Whether that turns on state-law limited partner status or on a functional analysis of the partner's role is now the subject of a split between the Tax Court and a circuit. The Tax Court held in 2023 that a functional analysis is required, reaffirmed it in a 2024 memorandum decision, and in May 2025 found on the merits that particular limited partners were limited partners in name only. In January 2026 a circuit reversed the Tax Court two to one, rejecting the functional analysis and holding that the exclusion turns on state-law limited partner status even where the partner actively participates. The government petitioned for rehearing en banc on 1 April 2026 and a separate appeal was argued the same year.

The only honest publication of that is as unsettled, with a jurisdictional caveat. There is no single national rule to state as of the date of this page, and any treatment that gives one is either out of date or overreaching.

The net investment income tax is the near-complement. It applies at three point eight per cent on the lesser of net investment income or the excess of modified adjusted gross income over a threshold. To the extent a manager's distributive share is income from a trade or business in which the manager materially participates, it is generally outside that tax; a passive or investment-character allocation is inside it. So the two questions push in opposite directions and both should be answered before either is relied on.

On the legislative pipeline, the load-bearing fact for 2026 is a negative one and it is the fact most often reported wrongly: the July 2025 reconciliation act did not amend the carried interest provision. Carried interest was excluded from the final legislation and the three-year period and the final regulations remain in force unchanged. That act did substantially change the small business stock provision, which is the source of the confusion. Two repeal bills are live in concept — one introduced in February 2025 that would replace the provision with an ordinary-rate regime plus self-employment tax, and a later bill built on annual deemed compensation — and neither is enacted. Cite the non-partisan congressional analyses rather than press coverage for the policy framing.

One elective structure belongs here because it addresses the holding-period problem directly and is routinely confused with a different arrangement. A carry waiver is a voluntary mechanism under which the general partner forgoes carried interest allocations on gains from investments held three years or less, in exchange for dollar-for-dollar catch-up rights against future eligible long-term gains. It is not a management fee waiver, and the two carry entirely different tax analyses.

Reporting is a two-sided regime. A passthrough entity furnishes each interest holder the information needed to apply the rule — the one-year and three-year distributive share amounts, the capital gains and losses excluded, capital interest gains and losses, and on request the disposition information including the look-through and related-person amounts. The owner taxpayer computes and reports its own recharacterisation amount.

The mechanics are specific and worth getting right, because the failure mode is severe. For returns filed after 31 December 2021 the passthrough attaches a worksheet to each holder's schedule, delivered through a named box and code on the partnership schedule. The owner taxpayer attaches its own worksheet plus two tables. On the disposition schedules, all gains and losses are reported as if the rule did not apply, and then a single adjustment line is entered in the short-term part with proceeds equal to the recharacterisation amount and an offsetting long-term entry with basis equal to that amount. Failure to report has a defined consequence: the one-year amount is not reduced by the exclusions and all items are treated as failing the three-year test, which is a full-recharacterisation default.

The small business stock exclusion interacts with carry in two places and is misdescribed in both. The exclusion lets a non-corporate taxpayer exclude a percentage of gain on stock acquired at original issuance from a qualifying domestic C corporation. The July 2025 act changed three things prospectively for stock acquired after 4 July 2025: a tiered exclusion of fifty per cent at three years, seventy-five per cent at four and one hundred per cent at five or more; a per-issuer cap raised to fifteen million dollars; and an aggregate gross assets ceiling raised to seventy-five million dollars. Stock acquired on or before that date stays permanently on the legacy rules.

The rate arithmetic on the partial tiers is where the published treatments go wrong, and the correction below states it. The non-excluded portion of that gain is twenty-eight per cent rate gain, not twenty per cent rate gain, which makes the effective rates on the partial tiers fourteen per cent at the fifty per cent tier and seven per cent at the seventy-five per cent tier before the three point eight per cent investment income tax, and fifteen point nine and seven point nine five per cent with it.

One load-bearing open question closes the section, and it must not be stated flatly in either direction. The pass-through of the exclusion to a partner requires the partner's share to be attributable to an interest held on the date the partnership acquired the stock and at all times thereafter. The likely reading of interest in that provision is an interest in partnership capital rather than in future profits — which would mean a typical carried interest with no stated capital at the acquisition date supports no exclusion for that holder. That is an interpretive position, not settled law, and it is the single most consequential open item for a manager expecting the exclusion to flow through carry.
