If you are structuring GP compensation for a US fund, Section 1061 of the Internal Revenue Code is the provision that will shape how your carried interest is taxed. It was added by the Tax Cuts and Jobs Act in 2017, and the core rule is simple: carried interest held for less than three years is taxed as short-term capital gains at ordinary income rates, not at the lower long-term rate. That is a federal rate difference of roughly 17 percentage points. On a $10 million carry distribution, that is about $1.7 million in additional tax [1].
I see first-time managers underestimate this. They assume carried interest automatically gets long-term treatment because the underlying fund investments are held for years. That is not how it works. The three-year clock runs on the interest itself, not on the portfolio companies. And if you get the structuring wrong at formation, you cannot fix it retroactively.
What counts as an applicable partnership interest
Section 1061 applies to "applicable partnership interests" (APIs). An API is any interest in a partnership that is transferred to or held by someone in connection with the performance of substantial services in an investment business [2]. If you are a GP receiving carry for managing a fund, your carry is almost certainly an API. There are narrow exceptions for interests tied to future capital contributions and for passive investors who perform no services, but these do not apply to most fund managers [3].
The related-party rules matter here too. If your spouse or a family member performs services for the fund and holds an interest, both interests can be treated as APIs. This trips up managers who involve family members in the management company without thinking through the aggregation consequences [2].
The three-year holding period
The holding period starts when the partnership interest is transferred to the service provider. Not when the fund starts investing. Not when the first close happens. When the interest is formally transferred [1]. If a GP joins mid-stream and receives an interest in an existing fund, the clock starts at that date. If you roll carry from one vehicle to another, the transfer can reset the three-year period [2].
For a fund with a typical 10-year life, the practical impact is this: distributions from exits in years one and two are taxed at ordinary income rates (up to 37% federal plus 3.8% net investment income tax). From year three onward, those distributions can qualify for long-term capital gains treatment (up to 20% plus 3.8% NIIT) [1]. The difference is real money.
Profits interest versus capital interest
This is the single most important structuring decision for carried interest, and most managers get it wrong or do not think about it at all.
A profits interest represents a share of future profits only. It has zero liquidation value at grant. A capital interest represents a share of partnership capital, including the right to assets in liquidation [4]. The distinction matters because Section 1061 applies different rules to each.
For a profits interest, the three-year holding period is straightforward: it runs on the interest itself. Hold it three years and your distributions get long-term treatment. For a capital interest, there is a look-through rule. The tax treatment depends on how long the underlying fund assets have been held, not just how long you have held the interest [4]. If the fund sells a portfolio company after 18 months, your share of the gain is short-term even if you have held the capital interest for five years.
For emerging managers with shorter expected hold periods, structuring carry as a profits interest avoids the look-through complexity entirely. This is the right answer for most first funds.
How different fund strategies are affected
The three-year holding period hits different strategies differently. Buyout and growth equity funds that hold portfolio companies for four to seven years usually clear the three-year threshold without difficulty, assuming the carry interest was transferred at fund formation. Venture capital funds are more exposed. Early-stage exits happen, and secondaries in years two and three are increasingly common. Every exit inside the three-year window is taxed at ordinary rates [1].
Credit and hedge fund strategies add another layer. If the manager holds a capital interest subject to the look-through rule, shorter-duration portfolio positions mean the gains will frequently be short-term regardless of how long the carry has been held [4]. This is why profits interest structuring matters even more for managers running strategies with higher turnover.
Separating carry from co-investment
Many GPs invest their own capital alongside the fund. That co-investment capital is not an API if it is a genuine capital contribution rather than compensation for services [5]. But you have to keep the two separate. If you combine carry and co-investment in a single partnership interest, the entire position can be subject to API rules, and your co-investment capital may be taxed at short-term rates unnecessarily [5].
Use separate vehicles or clearly segregated accounts for carry and co-investment. Define this at the LP agreement stage. Trying to separate them after the fact is messy and may not hold up under audit.
Common structuring mistakes
I see the same errors repeatedly with emerging managers:
- Starting the clock wrong. Managers assume the three-year period begins when the fund starts investing or when the management company is formed. It begins when the interest is formally transferred to the GP. Document the exact date [2].
- Defaulting to capital interest treatment. If your fund strategy involves shorter holds, a capital interest with look-through creates worse tax outcomes than a profits interest. Model both scenarios before your first close [4].
- Skipping the Section 754 election. Filing a 754 election with the partnership tax return allows basis adjustments that can reduce unnecessary capital gains taxes on distributions. Miss the filing deadline and you lose the benefit [2].
- Ignoring state taxes. The federal rate differential is the headline number, but state treatment varies. New York taxes both short-term and long-term gains at ordinary rates, so the federal planning matters more there. California's 13.3% rate applies to all gains but long-term treatment provides federal relief [5].
Schedule K-1 reporting
Carried interest gains flow through to the GP on Schedule K-1 from the fund partnership. Short-term gains appear on Line 6, long-term gains on Line 5 [6]. Many fund partnerships use supplemental schedules to identify which portions relate to APIs, which helps the GP and their CPA track the three-year holding period correctly.
If the GP holds carry through a holding company or blocker corporation, the K-1 items cascade through multiple levels. The short-term versus long-term classification must be preserved at each step. Get this wrong and your personal return will be incorrect [6]. The GP should report API gains on Form 8949, segregating short-term and long-term transactions, with the holding period analysis documented in workpapers [7].
Choosing the GP entity structure
How you hold the carried interest matters too. The simplest option is holding it in the GP's individual name. An S-corp can provide FICA tax savings but adds complexity to the Section 1061 analysis. A C-corp blocker may be useful if you expect later fund mergers or want to defer recognition, but it introduces a second layer of tax [2]. For most Fund I managers, the individual or single-member LLC approach is the cleanest starting point. You can always add structural layers for Fund II once the economics justify the complexity.
Planning ahead
The most important thing you can do is make structuring decisions before your first close, not during it. Decide whether your carry will be a profits interest or capital interest based on your expected fund hold periods. Document the transfer date precisely. Segregate carry from co-investment. File the 754 election with your first partnership tax return. And make sure your CPA actually understands Section 1061. Many are still getting up to speed [1].
If you expect major realizations in year four or later, transfer interests at or before the initial closing to maximize the three-year window. For Fund II, consider making transfers early to build holding period ahead of anticipated exits.
