The choice between an LP and an LLC comes down to one question: does your business need to separate passive investors from an active manager, or do all the owners want both liability protection and a say in operations? A limited partnership splits owners into a fully liable general partner and shielded, hands-off limited partners. A limited liability company gives every member a liability shield regardless of how involved they are. Everything else — taxes, transferability, formation — follows from that structural difference.
Who Is Personally on the Hook
In an LLC, every member has limited liability. A home, savings, and outside investments stay out of reach of business creditors, and that protection applies whether the member runs daily operations or never shows up. The shield doesn’t depend on staying passive.
A limited partnership divides owners into two very different classes. The general partner runs the business and carries unlimited personal liability for partnership debts. If the LP can’t pay a creditor, the general partner’s personal wealth is exposed. Limited partners risk only what they put in. Beyond that capital contribution, their personal assets are protected.
One older rule deserves an update. Under the Revised Uniform Limited Partnership Act of 2001, which most states have adopted, a limited partner is not personally liable for partnership obligations “solely by reason of being a limited partner, even if the limited partner participates in the management and control of the limited partnership.” The old “control rule” that stripped protection from any limited partner who got involved in management has been eliminated in most jurisdictions. A handful of states still follow older versions, so check your state’s adoption before assuming you can roll up your sleeves without consequence.
Who Runs the Business
An LLC can be member-managed, where all owners participate in decisions, or manager-managed, where designated individuals or outside managers handle operations. The operating agreement sets voting rights, approval thresholds, and authority. Capital and control are completely decoupled: a member who contributed 10% of the capital can hold 50% of the voting power if the agreement says so.
The LP is far more rigid. The general partner holds all operational authority and makes strategic decisions. Limited partners have no voice in daily management. That isn’t tradition, it’s the structural premise of the LP. Whoever shoulders the liability also controls execution. For investors who want to write a check and stay uninvolved, the separation is a feature.
The general partner owes fiduciary duties to the limited partners: a duty of loyalty (no self-dealing, no competing with the partnership, no diverting partnership opportunities) and a duty of care (no grossly negligent or reckless conduct). Those duties give limited partners legal recourse if the general partner mismanages the business. An LLC’s fiduciary obligations depend on the operating agreement and state law, but managers and managing members generally owe similar duties to the other members.
How the Owners Are Taxed
Both structures default to pass-through taxation. The entity files an informational return but pays no federal income tax itself. Profits and losses flow through to each owner’s personal return on Schedule K-1 and are taxed at the owner’s individual rate.1Internal Revenue Service. About Form 1065, U.S. Return of Partnership Income
A multi-member LLC defaults to partnership taxation, and a single-member LLC is a disregarded entity reported on Schedule C. LLCs can elect different treatment: Form 8832 to be taxed as a C-corporation, or Form 2553 to elect S-corporation status if the entity meets the eligibility requirements (no more than 100 shareholders, one class of stock, no nonresident alien shareholders, among others).2Internal Revenue Service.

Self-Employment Tax Is Where the Real Money Moves
Self-employment tax funds Social Security and Medicare. In 2026, the combined rate is 15.3%: 12.4% for Social Security on earnings up to $184,500, plus 2.9% for Medicare on all earnings.5Social Security Administration. Contribution and Benefit Base On a $200,000 distributive share, that’s roughly $28,000 before any income tax.
General partners pay self-employment tax on their distributive share because they actively manage the business.6Internal Revenue Service. Entities Limited partners get an explicit statutory carve-out. Under 26 U.S.C. § 1402(a)(13), a limited partner’s distributive share is excluded from self-employment tax. The only exception is guaranteed payments received for services actually rendered to the partnership.7Office of the Law Revision Counsel. 26 U.S. Code 1402 – Definitions
For LLC members the picture is murkier. The IRS proposed regulations in 1997 that would have clarified when an LLC member qualifies as a “limited partner” for self-employment tax purposes, but they were never finalized and remain in limbo.8Internal Revenue Service. Definition of Limited Partner for Self-Employment Tax Purposes Active LLC members generally pay self-employment tax on their distributive share. Passive LLC members sit in a gray zone where the answer depends on the facts, the state, and how aggressively you’re willing to file.
One common workaround: an LLC elects S-corporation treatment, pays active members a reasonable salary (subject to payroll tax), and distributes remaining profits as dividends free of self-employment tax. It works, but it adds payroll administration, W-2 filings, and IRS scrutiny of what counts as “reasonable” compensation. The LP delivers the self-employment tax exclusion to its limited partners without any of that machinery.
Moving Ownership In and Out
LLC membership interests are typically hard to transfer. Most operating agreements require majority or unanimous consent before a new person can become a full member with voting and management rights. An outsider who receives a transferred interest usually gets only distribution rights, not operational say. That protects co-owners from waking up in business with a stranger.
Limited partner interests are designed to be transferable. Because they carry no management rights, bringing in a new limited partner doesn’t change who runs the business. That transferability is one reason LPs dominate the investment fund world, where investors need the ability to sell or assign their stakes.
Continuity also plays out differently. An LLC generally survives the departure, death, or bankruptcy of a member without disruption, as long as the operating agreement includes continuation provisions. An LP’s continuity hinges on the general partner. Losing the general partner can trigger dissolution under many state statutes unless the partnership agreement names a successor or gives the limited partners a mechanism to appoint one.
Forming and Maintaining Each Entity
Forming an LLC means filing articles of organization (sometimes called a certificate of organization or certificate of formation) with the state’s filing office, typically the Secretary of State. The operating agreement, which governs internal operations, isn’t filed publicly but is the most important document for the business. It sets profit sharing, voting rights, capital contributions, buyout terms, and dispute resolution.
Forming an LP means filing a certificate of limited partnership with the state. That certificate is a public document naming the general partner and providing basic identifying information. The partnership agreement handles everything else: profit and loss allocation, fiduciary duties, restrictions on limited partners, and succession planning for the general partner.
Both entities must maintain a registered agent in their state of formation. The registered agent is the official contact point for lawsuits and government notices and must keep a physical address available during business hours. Commercial providers offer the service in every state.
Filing fees vary significantly, generally running from about $50 to $500 for initial formation. Many states also require annual or biennial reports and charge recurring fees to keep the entity in good standing. Some impose franchise taxes or minimum taxes regardless of income. These ongoing costs apply to both LLCs and LPs, though specific amounts differ by jurisdiction.
Which One Fits Your Business
The LP is built for situations where passive capital needs a clean boundary from active management. Private equity funds, venture capital vehicles, real estate syndications, and family investment partnerships gravitate toward it because the structure gives investors a defined role, transferable interests, and a statutory self-employment tax exclusion. The general partner controls strategy; the limited partners invest without operational entanglement. When a professional manager wants to raise money from outside investors while keeping full control, the LP is the natural fit.
The LLC works better when all or most owners want a hand in running the business. It’s the default for operating companies, professional practices, joint ventures among active participants, and smaller real estate holdings where the owners manage the property themselves. The flexibility of the operating agreement means an LLC can be shaped into almost any governance structure the owners negotiate, without the rigid general partner / limited partner divide.
Neither structure is universally better. The real question is whether your business separates capital from management or integrates them. If investors and operators are different people with different roles, the LP gives the passive side a proven framework with real tax benefits. If everyone at the table wants both a voice and a shield, the LLC delivers both without forcing anyone into a second-class seat.
