A limited partnership interest is an ownership stake in a limited partnership that pays you a share of the profits and losses without giving you any role in running the business. You’ll see these interests most often in private equity funds, venture capital vehicles, hedge funds, and large real estate deals, where a managing partner runs operations and passive investors put up capital. The trade-off is direct: your liability generally cannot exceed what you invested or committed to invest, but you give up control over how that money is deployed.
How the Structure Works
A limited partnership needs at least two kinds of partners. The general partner handles all management decisions and carries full personal liability for the partnership’s debts. The limited partner puts up capital, receives an ownership interest, and has no authority over operations and no personal exposure beyond the investment.1Legal Information Institute. Limited Partnership
That split between management and capital is what makes the structure work for investment funds. A professional firm serves as general partner and makes every buying, selling, and operating decision. Dozens or hundreds of limited partners pool their money into the fund, each holding an interest that represents their slice. The terms governing the whole relationship live in the partnership agreement, which is the single most important document you’ll sign as a limited partner. It covers profit splits, transfer restrictions, and how, if ever, the general partner can be removed.
What Rights Come with the Interest
Limited partners hold a defined set of protective rights, even without a say in daily operations. Under the partnership laws adopted in most states, you can inspect the partnership’s books and records and get relevant financial information. Partnership agreements typically require the general partner to deliver annual audited financial statements plus periodic unaudited reports, though frequency and detail vary by fund.
You can also vote on a narrow set of decisions that would fundamentally change the partnership. Those votes usually cover selling all or substantially all of the fund’s assets, extending the partnership’s term beyond its original expiration, or removing the general partner for cause. Outside those extraordinary events, limited partners have no vote and no veto over investment decisions.
The restriction holding the whole structure together is the ban on participating in management. A limited partner who crosses into actively controlling operations risks losing liability protection entirely and being treated as a general partner under state law. The federal tax code reinforces this 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 Where the line sits between permissible oversight and impermissible control is a state-law question and not always intuitive. Asking questions and reviewing reports is fine. Telling the general partner which investments to make is not.
Who Can Buy an LP Interest
Limited partnership interests are securities under federal law. That means they cannot be sold to the public unless they are registered with the SEC or qualify for an exemption. Nearly all private funds rely on Regulation D, most commonly Rule 506(b), which lets a fund raise unlimited money from an unlimited number of accredited investors without registering the offering.3U.S. Securities and Exchange Commission. Private Placements – Rule 506(b) The cost of that exemption is that the fund cannot publicly advertise the offering and can accept no more than 35 non-accredited investors.
To count as an accredited investor, you need to clear at least one of these thresholds:
- More than $1 million in net worth (individually or jointly with a spouse), excluding your primary residence.4eCFR. 17 CFR 230.501 – Definitions and Terms Used in Regulation D
- Individual income above $200,000 in each of the last two years, or $300,000 jointly with a spouse, with a reasonable expectation of the same 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.
Funds using Rule 506(c) can advertise publicly, but every investor must be accredited, and the fund must take reasonable steps to verify each one. In practice, when someone approaches you about an LP interest, a qualification check is the first thing that happens. Miss the thresholds and you won’t be offered the interest.
How the Money Moves
The financial relationship starts with a capital commitment. You rarely wire the full amount on day one. Instead, you commit a total, and the general partner draws down that commitment through capital calls as investments arise. Missing a capital call is a serious breach and can trigger penalties written into the partnership agreement, including forfeiture of part of your interest.
The partnership keeps a capital account for each limited partner, tracking contributions, allocated profits and losses, and distributions. That account is your running economic scorecard.
The Distribution Waterfall
When the fund generates cash from selling investments or receiving income, distributions follow a priority order called a waterfall. The typical sequence:
- Limited partners get their invested capital back first.
- Limited partners then receive a preferred return, often 7% to 8% annually on invested capital. Until that hurdle clears, the general partner receives nothing beyond its management fee.
- The general partner receives a catch-up, a disproportionate share of the next dollars, until it reaches its agreed profit percentage.
- Remaining profits split, commonly 20% to the general partner and 80% to limited partners.
That 20% profit share is carried interest, and it’s the main way fund managers get paid for performance. Under federal tax law, carried interest must be held for 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
Separately from the profit split, the general partner charges an annual management fee. This is typically around 2% of committed capital during the investment period and sometimes steps down to a percentage of invested capital afterward. The fee covers salaries, operating costs, and overhead, and it’s paid whether or not the fund makes money. That’s the private equity fee structure people describe as “2 and 20”: 2% each year for management, plus 20% of profits above the hurdle.
How LP Interests Are Taxed
Limited partnerships are pass-through entities for federal tax purposes. The partnership itself pays no income tax. Every item of income, gain, loss, deduction, and credit flows through to the 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’s what avoids the double taxation that hits C corporation shareholders.
Each year the partnership files Form 1065 as an informational return and sends each partner a Schedule K-1 showing their allocated share of income, deductions, and credits.7Internal Revenue Service. About Form 1065, U.S. Return of Partnership Income You need the K-1 to complete your own return. One practical headache: K-1s from private funds frequently arrive past the April filing deadline, so limited partners often file extensions.
Passive Activity Classification
Income from a limited partnership interest is generally passive, because the tax code assumes limited partners do not materially participate in the business.2Office of the Law Revision Counsel. 26 U.S.C. 469 – Passive Activity Losses and Credits Limited That classification matters most when the partnership generates losses. Passive losses can only offset passive income from the same or other passive investments. They cannot reduce your wages, salary, or portfolio income like dividends and interest.8Internal Revenue Service. Publication 925 – Passive Activity and At-Risk Rules Unused passive losses carry forward and can be used later when you have passive income to offset, or when you fully dispose of your interest.
Three Loss Limitations, Applied in Order
Before any share of partnership losses becomes deductible, it has to clear three hurdles in this order:
- Basis. You can only deduct losses up to your adjusted tax basis in the interest. Basis starts with your capital contributions, increases with your share of partnership income and certain partnership debt, and decreases with distributions and losses. Losses above basis are suspended and carry forward until additional contributions or income allocations restore it.9Office of the Law Revision Counsel. 26 U.S.C. 704 – Partner’s Distributive Share
- At-risk. Even with basis, you can only deduct losses to the extent you are economically at risk. Your at-risk amount generally includes money you contributed and amounts you borrowed for which you are personally liable, but not amounts protected by nonrecourse financing, guarantees, or stop-loss arrangements. For most limited partners, the at-risk amount equals actual cash invested, since 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. Losses that survive the first two hurdles still cannot offset non-passive income like wages or portfolio 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. This is where limited partners often get surprised at tax time: a large paper loss on the K-1 does not automatically produce a tax deduction.
Self-Employment Tax
One real advantage of limited partnership interests is that a limited partner’s distributive share is excluded from self-employment tax. You won’t owe the 15.3% self-employment tax on 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 taxed like ordinary earned income.
Qualified Business Income Deduction
Section 199A allowed eligible taxpayers to deduct up to 20% of qualified business income received through a partnership.12Internal Revenue Service. Qualified Business Income Deduction The deduction was enacted in the 2017 Tax Cuts and Jobs Act and was scheduled to expire after December 31, 2025. If you hold LP interests generating business income, check whether Congress has extended or modified the provision for 2026, because its availability directly affects your after-tax return.
Holding an LP Interest Inside an IRA
You can hold a limited partnership interest inside an IRA or other tax-advantaged retirement account, but that setup creates a tax trap. If the partnership uses debt financing, your retirement account may owe unrelated business income tax on the income that leverage produces.
When an IRA’s gross unrelated business taxable income reaches $1,000 or more, the IRA 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 allows a $1,000 specific deduction against this income, so small amounts of UBTI 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 treated separately for this purpose, so multiple IRAs each get their own UBTI calculation.
Many investors buy LP interests inside their IRAs, particularly master limited partnerships and leveraged real estate funds, assuming all income will be tax-deferred. When the K-1 arrives showing debt-financed income, they find out their supposedly sheltered account has produced a tax bill. Before placing any LP interest in a retirement account, find out whether the partnership uses leverage and how much UBTI it has historically thrown off.
Getting Out: Transfers and Assignments
LP interests are illiquid. There is no exchange where you can sell at the click of a button. 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 when transfers are allowed, additional hurdles usually apply. A right of first refusal lets the partnership or existing partners buy your interest on the same terms a third party has offered, which effectively blocks an outside sale by matching the price. Some agreements instead use a right of first offer, which requires you to offer the interest to existing partners before shopping it externally.
Most partnership agreements also draw a line between assigning your economic rights and transferring your full partnership 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 doesn’t become a partner. They get the cash flow, not the voting rights, information rights, or legal status. A full transfer, carrying all rights and obligations, virtually always needs the general partner’s approval.
The combined effect is that LP interests trade at a discount to net asset value on the secondary market. Discounts of 5% to 15% are common for high-quality funds and can run much steeper for weaker funds or those with long remaining lock-up periods. A secondary market does exist, with specialized brokers matching buyers and sellers, but liquidity is limited and transaction costs are meaningful. If you might need your capital on short notice, an LP interest is the wrong place for it.
