Partnership vs LLC: Which Structure Saves You More in Taxes

When two or more people start a business together, one of the first decisions they face is how to structure it. The choice between a general partnership, limited partnership, LLC, or LLP has real consequences for how much you pay in taxes, how much personal liability you carry, and how flexible you can be in dividing profits and losses. The wrong choice can cost you tens of thousands of dollars a year in unnecessary taxes or leave your personal assets exposed to business lawsuits.

In this guide, we compare the four most common multi-owner structures side by side -- looking at default tax treatment, liability protection, self-employment tax exposure, and the specific situations where each structure makes the most sense.

The Four Structures at a Glance

General Partnership (GP): The Default Nobody Should Accept

A general partnership is the simplest multi-owner structure -- and the most dangerous. It exists automatically whenever two or more people go into business together, even without a written agreement. There is no state filing, no formation cost, and no liability protection. Every general partner is personally liable for all partnership debts and obligations, including the negligence of the other partners.

From a tax perspective, a GP is a pass-through entity. The partnership files Form 1065 and issues K-1s to each partner. All income is subject to self-employment tax for all partners. On $300,000 of partnership income split 50/50, each partner owes self-employment tax of approximately $11,478 (the 2.9% Medicare tax on the full $150,000, plus 12.4% Social Security tax on income up to the wage base of $176,100 for 2026).

There is almost no situation where a general partnership is the right choice. The only advantage -- simplicity -- is not worth the unlimited personal liability.

Limited Partnership (LP): Protecting Passive Investors

A limited partnership has two classes of partners: general partners (who manage the business and have unlimited liability) and limited partners (who invest capital and have liability limited to their investment). Limited partners cannot participate in the day-to-day management of the business without risking their limited liability status.

The Tax Advantage of Limited Partnerships

Here is where LPs get interesting from a tax perspective. Under IRC Section 1402(a)(13), limited partners are generally excluded from self-employment tax on their distributive share of partnership income. Only guaranteed payments for services are subject to SE tax.

The trade-off is that the general partner carries unlimited personal liability. Many LP structures solve this by making the general partner an LLC itself, creating a layer of protection.

LLC: The Most Flexible Option

The LLC (limited liability company) is the most popular choice for new multi-owner businesses, and for good reason. Every member gets liability protection regardless of their role in management. There is no requirement to have a "passive" class of owners. And the operating agreement can be structured with almost unlimited flexibility in terms of profit sharing, voting rights, and management authority.

Default Tax Treatment

A multi-member LLC is taxed as a partnership by default. It files Form 1065, issues K-1s, and all the partnership tax rules apply -- including the ability to make special allocations, the Section 754 election, and the at-risk and passive activity loss rules.

The Self-Employment Tax Question

The SE tax treatment of LLC members is one of the most debated areas in tax law. Unlike limited partners in an LP, there is no clear statutory exclusion for LLC members. The IRS proposed regulations in 1997 that would have clarified the rules, but those regulations were never finalized. In practice, most tax advisors treat LLC members who are not active in management as exempt from SE tax -- similar to limited partners -- but this position carries some audit risk.

For members who are active in management, the full distributive share is generally subject to SE tax, just like a general partner.

The S Corp Election: An LLC Taxed as an S Corporation

An LLC can elect to be taxed as an S corporation by filing Form 2553. This is one of the most powerful tax planning strategies available to active business owners. When an LLC is taxed as an S corp, the owner-employees pay themselves a reasonable salary (subject to payroll taxes) and take the remaining profits as distributions (not subject to SE tax).

The S corp election makes the most sense when the business generates significantly more income than the owners' reasonable salaries. For a detailed analysis of when the S corp election is worth it, see The S Corp Tax Book.

However, electing S corp status means you lose the ability to make special allocations -- all S corp income must be allocated pro rata by ownership. If special allocations are important to your deal structure, stay with partnership taxation.

LLP: For Professional Firms

A limited liability partnership (LLP) is a variation designed primarily for professional service firms -- law firms, accounting firms, medical practices. In an LLP, each partner is protected from the malpractice or negligence of the other partners, but not from their own. All partners can participate in management without losing liability protection.

From a tax perspective, an LLP is treated identically to a general partnership. All partners' distributive shares are subject to self-employment tax. The advantage is purely on the liability side -- it provides a layer of protection between partners without requiring anyone to be a "limited" partner who cannot participate in management.

Not all states allow LLPs for all professions, so this option depends on state law.

Charging Order Protection: A Hidden Benefit of LPs and LLCs

Beyond taxes, LPs and LLCs offer an asset protection feature that general partnerships do not: charging order protection. If a partner is sued personally (for a car accident, personal debt, or other non-business claim), a creditor cannot seize the partner's interest in the LP or LLC. Instead, the creditor can only obtain a "charging order" -- a lien on any distributions the partnership makes to that partner. The creditor cannot force a distribution, cannot vote on partnership matters, and cannot access partnership assets.

In a general partnership, by contrast, a creditor can reach the partner's interest directly -- including forcing a liquidation of the partnership in some states. This distinction alone makes LLCs and LPs far superior to general partnerships for asset protection.

Which Structure Is Best for Your Situation?

• Active business with equal partners: Multi-member LLC (consider S corp election if income exceeds reasonable salaries by a significant margin)
• Real estate with passive investors: Limited partnership (LP) with an LLC as the general partner -- limited partners avoid SE tax on their share
• Professional services firm: LLP (if available in your state) or professional LLC
• Venture with special allocations needed: LLC taxed as partnership or LP -- do not elect S corp status if you need allocation flexibility
• General partnership: Convert to an LLC as soon as possible -- the liability exposure is not worth the simplicity

Making the Right Choice

Entity selection is not a one-size-fits-all decision. The right structure depends on the nature of the business, the number and type of owners, the expected income levels, whether special allocations are needed, and the importance of liability protection. The wrong choice can mean paying thousands more in SE tax every year or leaving personal assets exposed to business claims.
