A limited partnership interest is an ownership stake in a limited partnership that entitles you to a share of the profits and losses without any role in running the business. It shows up most often in private equity funds, venture capital vehicles, hedge funds, and large real estate deals, where a professional manager operates the fund and outside investors put up the capital. The core trade-off is simple. Your liability is capped at what you invested or committed to invest, and in exchange you give up any say in how the money is deployed.
What You Get and What You Give Up
A limited partnership needs at least two kinds of partners. The general partner makes every management decision and carries full personal liability for the partnership’s debts. The limited partner puts in capital, holds an ownership interest, and has no personal exposure beyond that investment.1Legal Information Institute. Limited Partnership That split is what makes the structure useful for pooled investing: one professional runs the shop, and many passive investors share the economics.
As a limited partner, you have defined rights even without a management role. Under most states’ partnership laws, you can inspect the books and request relevant financial information, and fund agreements typically require annual audited financials plus periodic unaudited reports. You can also vote on a narrow set of extraordinary matters — selling substantially all of the fund’s assets, extending the partnership’s term, or removing the general partner for cause. Outside those events, you have no vote on investment decisions.
The rule that holds all of this together is that you cannot participate in management. A limited partner who crosses into actively controlling operations risks losing liability protection and being treated as a general partner under state law. Federal tax law reinforces the passive posture by generally treating limited partnership interests as passive investments regardless of what the partner actually does.2Office of the Law Revision Counsel. 26 U.S.C. 469 – Passive Activity Losses and Credits Limited Reviewing reports and asking questions is fine. Directing the general partner’s investment choices is not.
The document that governs everything specific to your fund is the partnership agreement. It sets profit splits, transfer restrictions, reporting obligations, and the conditions for removing the general partner. Read it before you sign.
Who Is Allowed To Buy One
Limited partnership interests are securities under federal law, so they cannot be sold to the public without SEC registration or an exemption. Nearly all private funds rely on Regulation D, most often Rule 506(b), which allows unlimited fundraising from an unlimited number of accredited investors, no public advertising, and no more than 35 non-accredited investors.3U.S. Securities and Exchange Commission. Private Placements – Rule 506(b)
You are an accredited investor if you meet at least one of these:
- Net worth above $1 million, individually or jointly with a spouse, excluding the value of your primary residence.4eCFR. 17 CFR 230.501 – Definitions and Terms Used in Regulation D
- Individual income above $200,000 in each of the two most recent years, or $300,000 jointly with a spouse, with a reasonable expectation of the same level in the current year.4eCFR. 17 CFR 230.501 – Definitions and Terms Used in Regulation D
- An active Series 7, Series 65, or Series 82 license, regardless of income or net worth.
A fund using Rule 506(c) can advertise publicly, but every investor has to be accredited and the fund must verify each one. Either way, expect a qualification check before you are offered an interest.
How the Money Flows
The economic relationship starts with a capital commitment. You rarely hand over the full amount on day one. Instead, you commit a total, and the general partner draws that down through capital calls as deals arise. Missing a capital call is a serious breach and can trigger penalties in the partnership agreement, up to forfeiture of part of your interest.
The partnership keeps a capital account for you that tracks contributions, allocated profits and losses, and distributions. That account is your running scorecard.
The Distribution Waterfall
When the fund generates cash, distributions follow a priority order called a waterfall. A typical sequence:
- Return of capital. Limited partners first receive back the money they invested.
- Preferred return. Limited partners then receive a minimum annual return on invested capital, often 7% to 8%. Until this hurdle clears, the general partner receives nothing beyond its management fee.
- Catch-up. Once limited partners have received their preferred return, the general partner takes a disproportionate share of the next dollars until it reaches its agreed profit percentage.
- Carried interest split. Remaining profits split between the general partner and limited partners, commonly 20% and 80%.
The general partner’s 20% share is carried interest, the primary performance pay for fund managers. Under federal tax law, carried interest must be held more than three years to qualify for long-term capital gains rates; gains on interests held three years or less are taxed as short-term capital gains.5Internal Revenue Service. Section 1061 Reporting Guidance FAQs
Management Fees
Separate from the profit split, the general partner charges an annual management fee, typically around 2% of committed capital during the investment period and sometimes stepping down to a percentage of invested capital afterward. The fee gets paid whether the fund makes money or not. That is where “2 and 20” comes from: 2% annually for management, 20% of profits above the hurdle.
How the Income Is Taxed
Limited partnerships are pass-through entities for federal tax purposes. The partnership itself pays no income tax. Instead, every item of income, gain, loss, deduction, and credit flows through to the individual partners, who report their shares on their own returns.6Office of the Law Revision Counsel. 26 U.S.C. 702 – Income and Credits of Partner That avoids the double taxation that hits C corporations.
Each year the partnership files Form 1065 as an informational return and issues a Schedule K-1 to each partner showing their allocated share of the tax items.7Internal Revenue Service. About Form 1065, U.S. Return of Partnership Income The K-1 is what you need for your personal return. A practical warning: K-1s from private funds frequently arrive late, sometimes past the April deadline, so limited partners often file extensions.
Passive Income and Losses
Income allocated on an LP interest is generally treated as passive because the tax code presumes limited partners do not materially participate.2Office of the Law Revision Counsel. 26 U.S.C. 469 – Passive Activity Losses and Credits Limited That matters most on the loss side. Passive losses can only offset passive income. They cannot reduce your wages or portfolio income like dividends and interest.8Internal Revenue Service. Publication 925 – Passive Activity and At-Risk Rules Unused passive losses carry forward until you have passive income to absorb them or you fully dispose of your interest.
Three Hurdles Before a Loss Is Deductible
Before any share of partnership losses actually reduces your tax bill, the losses have to clear three separate limitations, in this order:
- Basis limitation. You can deduct losses only up to your adjusted tax basis in the interest. Basis starts with your capital contributions, increases with allocated income and certain partnership debt, and decreases with distributions and losses. Losses exceeding basis are suspended and carry forward until basis is restored.9Office of the Law Revision Counsel. 26 U.S.C. 704 – Partner’s Distributive Share
- At-risk limitation. Even with basis, you can deduct losses only to the extent you are economically at risk. Your at-risk amount generally includes money you contributed and amounts borrowed for which you are personally liable. It does not include amounts protected by nonrecourse financing, guarantees, or stop-loss arrangements. For most limited partners, the at-risk amount is the actual cash invested, because limited partners rarely guarantee partnership debt.10Office of the Law Revision Counsel. 26 U.S.C. 465 – Deductions Limited to Amount at Risk
- Passive activity limitation. Losses that survive the first two hurdles still cannot offset non-passive income.2Office of the Law Revision Counsel. 26 U.S.C. 469 – Passive Activity Losses and Credits Limited
Losses blocked at any stage carry forward. A large paper loss on a K-1 does not automatically become a deduction.
Self-Employment Tax
A limited partner’s distributive share of partnership income is excluded from self-employment tax, so the 15.3% Social Security and Medicare hit does not apply to your allocated profits.11Office of the Law Revision Counsel. 26 U.S.C. 1402 – Definitions The exception is guaranteed payments for services you personally render to the partnership, which are subject to self-employment tax like ordinary earned income.
Section 199A
The qualified business income deduction has allowed eligible taxpayers to deduct up to 20% of qualified business income received through a partnership.12Internal Revenue Service. Qualified Business Income Deduction It was enacted in the 2017 Tax Cuts and Jobs Act and was scheduled to expire after December 31, 2025. If you hold an LP interest that generates business income, check whether Congress has extended or modified the deduction for 2026 before you count on it.
The Retirement Account Trap
You can hold a limited partnership interest inside an IRA, but doing so creates a tax problem many investors miss. If the partnership uses debt financing, your IRA can owe unrelated business income tax on the income tied to that leverage.
When an IRA’s gross unrelated business taxable income reaches $1,000 or more, the trustee or custodian must file Form 990-T and pay the tax from the account’s assets.13Internal Revenue Service. Instructions for Form 990-T (2025) The tax code provides a $1,000 specific deduction against this income, so small amounts may not produce an actual tax bill, but the filing obligation still exists.14Office of the Law Revision Counsel. 26 U.S.C. 512 – Unrelated Business Taxable Income Each IRA is evaluated separately, so multiple IRAs holding LP interests are looked at independently.
The problem shows up most often with master limited partnerships and leveraged real estate funds bought inside an IRA under the assumption that everything will be tax-deferred. When the K-1 arrives with debt-financed income, the supposedly sheltered account has generated a tax bill. Before you place an LP interest in a retirement account, find out whether the partnership uses leverage and how much UBTI it has historically produced.
Getting Out Again
LP interests are illiquid. There is no exchange where you click to sell. The partnership agreement almost always requires the general partner’s written consent before you can transfer, and the general partner has broad discretion to refuse.
Even where transfers are allowed, agreements add hurdles. A right of first refusal lets the partnership or existing partners match a third-party offer and take the interest themselves. A right of first offer requires you to offer the interest to existing partners before shopping it outside.
Most agreements also separate the economic rights from full partner status. You may be able to assign the right to receive future distributions and capital returns without the general partner’s consent, but the assignee does not become a partner. They receive the cash flow without voting rights, information access, or the legal status of a limited partner. A full transfer, carrying all rights and obligations, virtually always requires the general partner’s approval.
Because of these restrictions, LP interests trade on the secondary market at a discount to net asset value. Discounts of 5% to 15% are common for high-quality funds and run steeper for funds with poor performance or long remaining lock-ups. A secondary market with specialized brokers does exist, but liquidity is limited and transaction costs are meaningful. If you might need your capital on short notice, a limited partnership interest is the wrong place for it.
