Operating Agreement vs LP Agreement: When You Get Which and Why It Matters

Sponsors talk about "limited partnership" deals and circulate operating agreements. They use the words GP and LP and run an LLC. The terminology is loose because the structures are functionally similar. The legal differences are smaller than they sound, but the ones that exist matter for tax, liability, and governance.

The Structural Difference

A limited partnership is a state-law entity formed under a state's Uniform Limited Partnership Act. It has at least one general partner with management authority and unlimited liability for partnership obligations, and one or more limited partners who provide capital and have liability limited to their investment.

A limited liability company is a state-law entity formed under a state's LLC Act. It has members (the equity owners) and is managed either by all members (member-managed) or by designated managers (manager-managed). Liability is limited for all members, regardless of role.

The structural difference is who bears unlimited liability. In an LP, the GP bears it. In an LLC, no one does. That is why modern syndications almost always use LLCs even when they call the structure a "limited partnership."

Why Most Modern Syndications Use LLCs

The shift to LLCs accelerated in the late 1990s and is now near-universal in real estate syndication. The reasons:

• Liability shield for the sponsor. A natural-person GP in an LP structure has unlimited personal liability for partnership debts. To solve this, sponsors form a corporate or LLC GP. That works but adds an entity. An LLC structure with a manager is simpler and provides the same shield directly.
• Drafting flexibility. LLC statutes are more permissive than LP statutes. The operating agreement can customize almost anything. Some LP statutes are more rigid, particularly on voting, withdrawal, and distribution.
• Familiarity. Real estate operators are used to LLCs from their property-level entities. Using LLCs at the syndication level matches the rest of the operating stack.
• Tax neutrality. Both LPs and multi-member LLCs are taxed as partnerships by default. There is no tax advantage to either form for most real estate deals.

Sponsors often retain the partnership terminology even when using an LLC because the language is familiar to investors. A document called the "Limited Partnership Agreement of [Sponsor] Real Estate Fund I, LLC" is not unusual. The entity is an LLC. The agreement uses LP terminology. Both are common.

Member vs Limited Partner Terminology

The terminology maps roughly as follows:

Some operating agreements use a hybrid vocabulary: "Manager" alongside "Limited Partner," or "Sponsor" alongside "Investor Member." The labels are cosmetic. The substantive rights are determined by the document, not the term used.

Manager vs General Partner Authority

The scope of authority granted to the GP or Manager is functionally identical in most modern syndications. Both documents grant broad day-to-day authority subject to a list of "Major Decisions" that require investor consent.

The technical difference is in default authority under state law. Under most LP statutes, the GP has plenary authority over partnership affairs unless the LPA restricts it. Under most LLC statutes, the default in a manager-managed LLC is similar but the operating agreement is more often the operative source of authority. In both cases, the document controls.

The substantive question for an LP or Member is the list of Major Decisions, not whether the entity is an LLC or LP. The carve-outs requiring investor consent matter regardless of the form.

Voting Thresholds and Consent Rights

Voting mechanics differ slightly between LPs and LLCs in default state law, but practical drafting eliminates most of the difference.

Under Delaware LP law, limited partners cannot participate in management without risking loss of limited liability. The "control rule" is mostly defanged in modern statutes (Delaware's safe-harbor provisions list 17 categories of LP activity that do not constitute control), but it lingers as a drafting concern.

Under Delaware LLC law, there is no equivalent rule. Members can participate in management as the operating agreement permits, without affecting their liability shield. This makes LLCs more flexible for governance structures that grant LPs material consent rights.

In practice, both documents end up with similar voting thresholds:

• Major decisions: 50.1% to 75% of capital interests
• Document amendments: 75% or higher
• Manager/GP removal for cause: 66.7% to 75%

Tax Treatment

Both LPs and multi-member LLCs are taxed as partnerships by default. Income, gain, loss, and deduction flow through to the equity owners' personal returns. Both file Form 1065 and issue K-1s.

The one substantive tax difference involves self-employment tax. A general partner in an LP is treated as a self-employed individual for SE tax purposes on their share of partnership ordinary income. A managing member of an LLC is in a more complex position. The IRS has long-standing proposed regulations (issued 1997, never finalized) treating member-managers similarly to general partners for SE tax. The practical answer depends on facts and circumstances.

For passive LPs and Investor Members, the SE tax issue rarely matters. Real estate rental income is generally exempt from SE tax under Section 1402(a)(1) regardless of the entity form. The SE tax exposure is on the GP/Manager side of the deal.

Liability Shield Differences

This is where the structures genuinely diverge.

In an LP, the GP has unlimited liability for partnership obligations. The limited partners are protected as long as they do not participate in management beyond the statutory safe harbors. If you are an LP and you sign a guaranty, vote on operational matters outside the safe harbor, or hold yourself out as a general partner, you can lose limited liability protection.

In an LLC, all members are protected by the limited liability shield regardless of their role. A member-manager who actively manages the company has the same liability protection as a passive member who has never visited the office. The shield can be pierced for the same reasons it can be pierced in a corporation: undercapitalization, commingling, fraud. But the default is full protection for everyone.

For passive investors, this difference is theoretical. You are not signing guarantees. You are not active in management. The LP liability shield protects you in either form. The difference matters more for the sponsor side and for joint ventures where investors take active operational roles.

What to Look for in Either Document

The substantive review is identical regardless of form. The questions to answer:

• What is the waterfall and how is each tier defined?
• What capital calls can the GP/Manager make beyond the original commitment?
• What are the consequences of a missed capital call?
• What decisions require investor consent?
• What information rights do investors have?
• Under what circumstances can the GP/Manager be removed?
• What is the indemnification scope and are the standard carve-outs included?
• Is the push-out election under the BBA audit rules mandatory?
• What confidentiality restrictions apply to investor communications?

If the document is an operating agreement, mentally substitute "Manager" for "GP" and "Member" for "LP" while reading. The substantive analysis does not change. If a clause would concern you in an LP context, it should concern you in an LLC context as well.
