A private equity partnership is a pooled investment vehicle in which a management firm and a group of investors join to buy, improve, and sell private companies. The structure has two roles. A general partner runs the fund and makes the investment decisions. Limited partners put up most of the capital and stay hands-off. That division shapes everything else: who is liable, who gets paid first, and how the tax bill is split. The economics most funds run on are commonly summarized as “2 and 20,” a 2% annual management fee plus 20% of profits above a performance threshold.
Legal Structure and Liability
Nearly all private equity funds are organized as limited partnerships under Delaware law, even when the manager’s offices and the target companies sit elsewhere. Delaware’s statute gives drafters wide latitude and its courts have produced a deep body of decisions, which makes outcomes more predictable when a dispute arises.
The general partner handles day-to-day operations: sourcing deals, negotiating acquisitions, managing portfolio companies, and choosing when to sell. That authority carries a cost. Under limited partnership law, the general partner has unlimited personal liability for the fund’s obligations. To contain that risk, the general partner entity is itself usually a limited liability company, so the individuals behind the firm are not personally exposed when a deal goes badly.
Limited partners sit at the opposite end. They commit capital and receive reports, but they don’t run the business. In exchange for that passive role their exposure is capped at what they’ve committed. A limited partner who commits $10 million can lose $10 million; creditors cannot reach the partner’s other assets. The protection holds only while the limited partner stays passive. Under Delaware’s statute, a limited partner who participates in controlling the business can become liable to people who dealt with the fund reasonably believing that partner was a general partner.
Who Can Invest
Private equity funds are not open to the public. They rely on exemptions from the Investment Company Act of 1940 that let them operate without registering, and those exemptions dictate who can put money in.
3(c)(1) Funds and Accredited Investors
The most common exemption, Section 3(c)(1), caps the fund at 100 beneficial owners and bars any public offering of its securities.1Office of the Law Revision Counsel. 15 USC 80a-3 Definition of Investment Company Funds using it typically require investors to be accredited under SEC rules. An individual qualifies with net worth above $1 million (excluding a primary residence) or annual income above $200,000 individually or $300,000 jointly with a spouse, in each of the two most recent years, with a reasonable expectation of the same level in the current year.2U.S. Securities and Exchange Commission. Accredited Investors
3(c)(7) Funds and Qualified Purchasers
Larger funds often use Section 3(c)(7), which has no statutory cap on the number of investors but requires each one to be a qualified purchaser.1Office of the Law Revision Counsel. 15 USC 80a-3 Definition of Investment Company The threshold is higher: an individual must own at least $5 million in investments (excluding a primary residence and personal-use property), and an institution acting on a discretionary basis must own and invest at least $25 million.3Office of the Law Revision Counsel. 15 USC 80a-2 Definitions Separate securities registration rules create a practical ceiling of roughly 2,000 investors before further regulatory obligations kick in.
Regulation D Offerings
Either exemption is usually paired with an offering under Rule 506(b) of Regulation D, which prohibits general solicitation and advertising and limits the fund to no more than 35 non-accredited investors.4U.S. Securities and Exchange Commission. Private Placements – Rule 506(b) The fund must file a Form D notice with the SEC within 15 days of the first sale.5U.S. Securities and Exchange Commission. Filing a Form D Notice Most states add their own notice filings and fees.
What the Partnership Agreement Controls
The limited partnership agreement governs every meaningful aspect of the fund’s life: the investment mandate, the fund’s term, how fees work, what rights limited partners hold, and how disputes get resolved. Negotiating this document is where institutional investors spend the most time before committing capital.
Fund Term
Most funds are set at ten years, with one or two extension years that let the general partner finish selling remaining companies. Extensions typically require limited partner consent or, at minimum, approval from the advisory committee. The fixed lifespan is what distinguishes private equity from open-ended vehicles like hedge funds, and it puts every deployment and exit on a clock.
Management Fees and Offsets
The management fee is commonly around 2% of committed capital per year during the investment period. It funds the firm’s operating costs: salaries, office, travel, and the diligence work behind evaluating acquisitions. Many agreements shift the fee base from committed capital to invested capital once the investment period ends, which reduces the dollar amount as companies are sold.
Sophisticated limited partners negotiate hard on the fee offset. General partners often collect transaction fees at acquisition and monitoring fees from portfolio companies they control. A fee offset clause credits 50% to 100% of those amounts against the management fee owed by investors. A 100% offset means every dollar the manager pulls from a portfolio company reduces the management fee by a dollar, which prevents double charging for the same involvement.
Governance and the Advisory Committee
Institutional-quality funds create a Limited Partner Advisory Committee, usually made up of the largest investors. The committee reviews conflicts, such as manager co-investments alongside the fund or transactions involving affiliated companies. It also weighs in on term extensions and on transactions that fall outside the stated mandate. Members don’t manage the fund, but they check the general partner’s discretion where the manager’s interests could diverge from investors’.
The agreement also sets the voting thresholds for major actions: removing the general partner for cause or without cause, changing strategy, or dissolving the fund early. Investors provide tax documentation, including Form W-9 for U.S. persons or Form W-8BEN for foreign individuals, to meet federal reporting and withholding rules.6Internal Revenue Service.

Capital Calls and Defaults
Limited partners don’t wire their full commitment upfront. The general partner draws it down through formal capital call notices as investments come up. Each notice states the amount due, wire instructions, and the purpose, whether an acquisition, expenses, or fees. Investors keep uncalled capital working elsewhere until it’s needed.
Agreements typically require funding within ten business days of the notice. The remedies for missing that deadline are deliberately harsh: penalty interest on the late amount, forfeiture of part of the existing interest, forced sale of the interest at a steep discount, or in extreme cases loss of the entire stake. These consequences exist because one investor’s failure to fund can sink a time-sensitive deal. The general partner can also call the missing amount from non-defaulting investors, provided no one is pushed past their total commitment.
Selling on the Secondary Market
A limited partner who needs liquidity before the fund’s term ends can sell their interest to another investor on the secondary market. The buyer takes both the existing stake and any unfunded commitment. These trades are more complex than selling public securities: there is no exchange, each interest requires individual valuation, and the general partner almost always holds a right to approve or block the transfer. Sellers frequently accept a discount to net asset value, particularly in a market downturn or early in the fund’s life while the portfolio is still being built.
The Distribution Waterfall
When the fund sells a portfolio company, the proceeds don’t split evenly. They flow through a multi-stage hierarchy, the distribution waterfall, that fixes who gets paid and in what order.
Return of Capital and Preferred Return
The first dollars out go to limited partners until they’ve recovered 100% of the capital they contributed. Until investors are whole on a dollar-for-dollar basis, the general partner receives nothing beyond the management fee already collected. Next comes the preferred return, a minimum annual return that limited partners must earn before the manager shares in profits. The industry standard is 8% per year, compounded on invested capital. If the fund’s investments don’t clear that hurdle, the general partner earns no performance compensation.
Catch-Up and Carried Interest
Once limited partners have received their capital plus the preferred return, the general partner enters the catch-up phase. The manager receives a disproportionate share of the next dollars, often 100%, until the general partner’s cumulative share of total profits reaches the agreed percentage. The catch-up ensures that once the hurdle is cleared, the overall split reflects the target ratio rather than leaving the manager permanently behind.
After the catch-up is satisfied, remaining profits are split under the carried interest provision. The standard is 20% to the general partner and 80% to the limited partners. That 20% carry is the primary economic incentive for the management team.
Clawback
Most agreements include a clawback provision that guards against the general partner keeping more carry than the fund’s overall performance ultimately justifies. The issue is most acute in funds that calculate carry deal-by-deal rather than across the whole portfolio: the manager may collect on early winners and then run into losses later. The clawback requires the general partner to return the excess, usually calculated at the end of the fund’s life. Enforcement can be difficult if the individuals who received the distributions have already spent or reinvested the money, which is why some agreements require the manager to escrow a portion of the carry as it’s paid.
Tax Treatment
The partnership form is a tax choice as much as an organizational one. A limited partnership is a pass-through entity: the fund itself pays no federal income tax, and all income, gains, losses, deductions, and credits flow through to the partners, who report them on their own returns.7Office of the Law Revision Counsel. 26 USC 701 Partners, Not Partnership, Subject to Tax That avoids the double taxation corporations face on distributed profits.
K-1 Reporting
Each year the partnership files Form 1065 with the IRS and issues a Schedule K-1 to every partner showing that partner’s share of the fund’s income, deductions, and credits.8Internal Revenue Service. About Form 1065 U.S. Return of Partnership Income K-1s from private equity funds tend to arrive late, sometimes well past the April individual filing deadline, which is why many limited partners file extensions as a matter of routine. The character of each item also passes through. A long-term capital gain at the fund level is a long-term capital gain to the partner; ordinary income remains ordinary income.
Carried Interest and the Three-Year Hold
Under Section 1061 of the Internal Revenue Code, the general partner’s 20% profit share qualifies for long-term capital gains rates only if the fund held the underlying investment for at least three years. If a portfolio company is sold in less than three years, the carry tied to that deal is taxed at short-term capital gain rates, which are the same as ordinary income rates. The rule pushes fund managers toward longer holding periods.
UBTI for Tax-Exempt Investors
Pension funds, endowments, and other tax-exempt organizations are major limited partners. Their tax-exempt status does not fully protect them when investing through a partnership. If the fund’s activities generate unrelated business taxable income, the tax-exempt partner owes tax on its share.9Office of the Law Revision Counsel. 26 USC 512 Unrelated Business Taxable Income The most common trigger is debt-financed income. When a fund uses leverage to buy a company, the portion of the gain attributable to borrowed money can create UBTI for tax-exempt partners.10Internal Revenue Service. UBIT Special Rules for Partnerships Some funds address this by offering parallel investment vehicles, sometimes structured as corporations that absorb the entity-level tax but keep the tax-exempt investor clear of UBTI reporting.
Distributions and Basis
When the fund distributes cash, the tax result depends on the partner’s adjusted basis in the interest. A partner generally does not recognize gain on a distribution unless the cash exceeds basis; anything above basis is treated as gain from the sale of the partnership interest.11Office of the Law Revision Counsel. 26 USC 731 Extent of Recognition of Gain or Loss on Distribution Capital calls, income allocations, and prior distributions all change basis, so tracking it accurately over a ten-year life is an ongoing exercise most limited partners hand to their tax advisors.
Regulation of the Manager
The fund itself avoids registration through the Investment Company Act exemptions above, but the manager faces its own rules. An investment adviser managing more than $150 million in private fund assets generally must register with the SEC under the Investment Advisers Act of 1940, with a narrower exemption for advisers to venture capital funds. Registered advisers are subject to SEC examination, recordkeeping, and fiduciary obligations to clients.
In 2023 the SEC adopted rules that would have required quarterly performance reporting, mandatory annual audits, and restrictions on preferential side-letter terms. The Fifth Circuit vacated those rules in June 2024, holding that the SEC lacked authority to adopt them. The pre-2023 framework remains in place, and private fund advisers continue to operate under the existing registration and disclosure requirements.
