A limited partnership is a business owned by two classes of partners: at least one general partner, who runs the operation and is personally on the hook for its debts, and at least one limited partner, who puts up money, shares in the profits, and can lose only what they invested. That division between control and capital is the whole point of the structure. It lets investors fund a business with a capped downside while the operators keep full authority over how the business is run.
The Two Partner Roles
The framework for most limited partnerships comes from the Uniform Limited Partnership Act, which most states have adopted in some form. The Act draws a hard line between the two classes, and everything else flows from that line.
General partners run the business. They sign contracts, hire, manage the money, set strategy, and make every operational call. A general partner is an agent of the partnership and can bind it to obligations, with roughly the same authority a sole owner would have.
Limited partners are passive investors. They contribute cash or property and take a share of the profits, but they have no voice in day-to-day operations. The law treats them more like shareholders in a corporation than co-owners of a business. If a limited partner starts making management decisions, they risk being reclassified and losing the liability shield that made the role attractive in the first place.1H2O: Business Associations. Limited Partnerships
A limited partnership must always have at least one partner of each type. If it drops below that minimum because someone leaves, the partnership has 90 days to fill the gap or face dissolution.1H2O: Business Associations. Limited Partnerships
Who Is Liable for What
The liability split is the defining feature of the structure and the main reason people choose it over a general partnership.
General partners carry unlimited personal liability for the partnership’s debts and judgments. If the business can’t cover what it owes, creditors can reach the general partner’s personal bank accounts, real estate, and other assets. Many general partners soften that exposure by putting an LLC or corporation in the general partner slot rather than serving personally.
Limited partners can lose only what they contributed. A limited partner who put in $50,000 cannot be forced to pay more if the business faces a million-dollar judgment. That protection holds as long as the limited partner stays out of management.
The Control Rule
Limited partners lose their shield when they cross into active management. Under older versions of the Uniform Limited Partnership Act, even consulting with general partners on strategy could be risky. Modern versions are more permissive and list activities that don’t count as “participating in control,” such as voting on whether to sell the business, admit new partners, or amend the partnership agreement. The safe harbor is broad, but the underlying rule hasn’t changed: limited partners who behave like general partners get treated like general partners.
Personal Guarantees
Whatever the statute says about liability, lenders routinely ask general partners to sign personal guarantees on business loans. A personal guarantee is a separate contract that makes the signer responsible for the full debt if the partnership defaults. An unlimited, joint-and-several guarantee, the type lenders prefer, lets the lender pursue any guarantor for the entire outstanding balance.2NCUA Examiner’s Guide. Personal Guarantees
How a Limited Partnership Is Taxed
A limited partnership doesn’t pay income tax at the entity level. It files an informational return on IRS Form 1065 and issues a Schedule K-1 to each partner reporting their share of income, deductions, and credits. Each partner then reports those items on their own return and pays tax at their personal rate.3Internal Revenue Service. About Form 1065, U.S. Return of Partnership Income
The character of each item carries through. Capital gains at the partnership stay capital gains on the partner’s return, and ordinary losses stay ordinary losses. This pass-through treatment avoids the double taxation that hits C corporations, where the company pays tax on profits and shareholders pay again on dividends.4Office of the Law Revision Counsel. 26 U.S. Code 702 – Income and Credits of Partner
Self-Employment Tax
The biggest tax benefit of being a limited partner is the self-employment tax exclusion. A limited partner’s share of partnership income is generally excluded from Social Security and Medicare taxes, with an exception for guaranteed payments received for services actually rendered to the partnership.5Office of the Law Revision Counsel. 26 U.S. Code 1402 – Definitions
General partners owe self-employment tax on their entire distributive share. For a profitable partnership, the gap can run into thousands of dollars a year, and it’s one reason the LP structure has held on for investment vehicles even as LLCs have taken over for operating businesses.
The QBI Deduction
Partners in a limited partnership have also been eligible for the Section 199A qualified business income deduction, which allows a deduction of up to 20 percent of qualified income from a pass-through entity.6Internal Revenue Service. Qualified Business Income Deduction Guaranteed payments for services don’t count toward QBI. The deduction was originally set to expire at the end of 2025, but proposed legislation in the One Big Beautiful Bill Act would make it permanent and raise the rate to 23 percent starting in 2026. Confirm the current status with a tax professional, since the final terms may have shifted during the legislative process.
The Partnership Agreement
Filing with the state creates the legal entity, but the partnership agreement is what actually governs the relationship between the partners. It’s the internal operating manual. A workable agreement covers at minimum:
- Each partner’s ownership percentage and how it was earned, whether through cash, property, or services.
- The formula for allocating profits and losses, which doesn’t have to match ownership percentages.
- Which decisions the general partner can make alone and which require a vote, such as selling the business, taking on major debt, or admitting new partners.
- How a partner exits, whether interests can be sold or assigned, and any transfer restrictions.
- The order in which creditors get paid and how remaining assets are divided if the partnership winds down.
Without clear language on these points, partners often end up in court arguing over what they thought they had agreed to. The agreement is a private contract and typically doesn’t get filed with the state, but every partner should hold a signed copy.
Buy-Sell Provisions
The buy-sell clause is one of the most important provisions and the one partners most often skip or draft poorly. It specifies what happens to a partner’s interest on a triggering event such as death, disability, retirement, or bankruptcy, and it locks in a valuation method so no one is fighting over what the interest is worth during an already hard transition. Common approaches include an EBITDA multiple, a book-value formula with adjustments, or an independent appraisal at the time of the event. The best agreements have partners revisit and update the valuation annually so it doesn’t go stale.
Forming and Maintaining the Entity
Creating a limited partnership starts with filing a certificate of limited partnership with the state. This is a public document and usually asks for:
- The partnership’s name, which must include a designator like “L.P.” or “Limited Partnership.”
- The name and address of a registered agent to receive legal documents.
- The principal office address.
- The full legal names and addresses of every general partner.
Some states also want a brief description of the business purpose or a set dissolution date. The form is normally available through the Secretary of State’s website or the equivalent commercial filing office. After filing, the partnership should get a federal Employer Identification Number from the IRS (free) and open a business bank account to keep partnership funds separate from personal ones.
Filing fees vary a lot by state, from under $100 in some places to several hundred dollars in others, with a few outliers considerably higher.
Doing Business in Another State
If a limited partnership operates in a state other than the one where it was formed, it generally has to register there through foreign qualification. That usually means filing a certificate of authority with the second state’s filing office and appointing a registered agent there. States consider you to be doing business locally if you maintain a physical location, employ people, or regularly enter into contracts in their jurisdiction. Skipping this step can trigger penalties and leave you unable to enforce contracts in that state’s courts.
Annual Reports and Good Standing
Forming the partnership isn’t a one-time task. Most states require limited partnerships to file periodic reports, usually annually or biennially, updating the state on the current address, registered agent, and general partner information. Fees for these reports commonly run from $20 to $500.
Missing these filings or letting the registered agent lapse can lead to administrative dissolution, where the state revokes the partnership’s authority to do business. Reinstatement is usually possible but involves back fees and paperwork. During a lapse, the partnership may lose the ability to sue in state court, and in some states the general partner can become personally liable for obligations incurred while the entity is dissolved.
LP Interests Are Usually Securities
One point that catches new organizers off guard: limited partnership interests are generally treated as securities under federal law. The Supreme Court’s investment contract test in SEC v. Howey asks whether someone invested money in a common enterprise with an expectation of profits from the efforts of others. LP interests check every box, since limited partners contribute capital, pool it in a shared venture, expect returns, and rely on the general partner to produce them.7SEC.gov. Framework for Investment Contract Analysis of Digital Assets
Selling LP interests to outside investors therefore usually requires either registering the offering with the SEC or fitting within an exemption, such as Regulation D for private placements. Getting this wrong can expose the general partner to securities fraud liability. If you’re raising capital from passive investors through an LP, plan on having a securities attorney involved from the start.
LP vs. LLC, and the LLLP Option
The limited liability company has largely displaced the limited partnership as the default choice for new businesses. In an LLC, every member gets liability protection by default, no one has to accept unlimited personal exposure, and members can take part in management without losing their shield. An LLC can also be run by all its members or by appointed managers, giving it flexibility the LP’s two-class structure doesn’t allow.
Where the limited partnership still holds an edge is tax planning. The self-employment tax exclusion for limited partners under IRC Section 1402(a)(13) is well-established and has been upheld by federal courts.5Office of the Law Revision Counsel. 26 U.S. Code 1402 – Definitions LLC members active in management generally owe self-employment tax on their full share of profits, and the IRS has never issued final regulations clarifying which LLC members qualify for a comparable exclusion. For investment funds, family estate planning vehicles, and real estate syndications, that gap keeps the LP structure in play.
A limited liability limited partnership, or LLLP, is a newer variation available in some states. It works like a standard LP except the general partner also gets limited liability protection, which removes the biggest downside of the traditional structure. In states that authorize LLLPs, the format pairs the tax advantages of an LP with the liability protection of an LLC for every partner. States that don’t recognize the LLLP simply don’t offer the option, so the state of formation matters.
