LLC vs LLP: Which Structure Is Right?

Understanding the Difference

An LLC (Limited Liability Company) and an LLP (Limited Liability Partnership) are both business structures that provide liability protection to their owners, but they are designed for different situations and operate under different rules. The choice between them depends on your business type, your profession, your state's laws, and how you want to manage your business.

An LLC is the most versatile business structure in the United States. It can be formed by one or more individuals (called members), can operate in virtually any industry, and offers maximum flexibility in management structure, profit distribution, and taxation. More than 2.5 million LLCs are formed each year, making it the most popular choice for new businesses across all industries.

An LLP is a specialized form of partnership designed primarily for licensed professionals — lawyers, accountants, architects, engineers, doctors, and other professionals who are typically required by their state licensing board to practice through a partnership rather than a corporation or LLC. LLPs are a relatively newer structure and are not available for all business types in all states.

Liability Protection

Both LLCs and LLPs provide some form of liability protection, but the scope of that protection differs significantly. In an LLC, all members receive full liability protection. Personal assets are shielded from business debts, lawsuits, and obligations. If the LLC is sued, only the LLC's assets are at risk — members' personal homes, cars, savings, and retirement accounts are generally protected (assuming the LLC is properly maintained and the corporate veil is intact).

In an LLP, partners are protected from the negligence and misconduct of other partners, but the extent of protection varies by state. In most states, each partner in an LLP is still personally liable for their own negligence, malpractice, or wrongful acts. The LLP protects you from claims arising from your partners' mistakes, but not from your own. Some states offer "full shield" LLP protection (similar to LLC protection), while others offer only "partial shield" protection (protecting only against claims arising from other partners' actions).

This distinction is critical for professional service firms. If you are a partner in a law firm structured as an LLP and your partner commits malpractice, you are generally not personally liable for that claim. But if you commit malpractice, your personal assets are exposed. In an LLC (in states that allow professionals to form LLCs), all members receive full liability protection regardless of who caused the claim.

Formation and Availability

LLC formation is straightforward and available in all 50 states for virtually any type of business. You file Articles of Organization with the Secretary of State, pay the filing fee, and your LLC exists. There are no restrictions on who can form an LLC or what industries can use the structure (with the exception of certain professions in certain states that require a Professional LLC or PLLC).

LLP formation is more restrictive. Not all states allow LLPs, and those that do often limit them to specific professions. Some states (like California) allow LLPs only for licensed professionals such as lawyers, accountants, and architects. Other states allow LLPs for any type of business. To form an LLP, you file a registration statement with the Secretary of State — similar to LLC formation but specific to partnerships.

A key difference: you need at least two partners to form an LLP (it is a partnership, after all), while an LLC can be formed by a single member. If you are a solo professional, an LLC (or PLLC) is your only option — you cannot form a one-person LLP.

Taxation

Both LLCs and LLPs offer pass-through taxation by default, meaning profits and losses pass through to the owners' personal tax returns without being taxed at the entity level. This avoids the double taxation that affects C-Corporations.

Single-member LLCs are taxed as sole proprietorships. Multi-member LLCs are taxed as partnerships. Both can elect S-Corporation taxation if beneficial. LLPs are always taxed as partnerships — each partner reports their share of profits and losses on their personal tax return.

The S-Corp election is a significant advantage for LLCs. Once your net profits exceed approximately $40,000-$50,000, electing S-Corp taxation allows you to pay yourself a reasonable salary (subject to payroll taxes) and take remaining profits as distributions (not subject to self-employment tax). This can save thousands of dollars per year in self-employment taxes. LLPs generally cannot make this election as easily — the S-Corp election for a partnership requires conversion to a different entity type.

Management Structure

LLCs offer maximum flexibility in management. You can choose member-managed (all members participate in management decisions) or manager-managed (one or more designated managers run the business while other members are passive investors). The operating agreement can create any management structure you want — committees, voting thresholds, delegation of authority, and so on.

LLPs operate under partnership rules. All partners typically have equal management rights and authority unless the partnership agreement says otherwise. Decisions are made by majority vote of partners in most cases. While you can customize the management structure through the partnership agreement, the default rules favor equal participation by all partners.

When to Choose an LLC

Choose an LLC if you are starting a business in any industry (not limited to professional services), you want maximum flexibility in management and profit distribution, you want the option to elect S-Corp taxation as your income grows, you are a solo entrepreneur (single-member LLC), you want the strongest possible liability protection, or your state does not allow your profession to form an LLP.

When to Choose an LLP

Choose an LLP if you are a licensed professional (lawyer, accountant, architect, engineer) in a state that allows or requires LLP formation for your profession, you are forming a partnership with other licensed professionals, your state licensing board requires partnership structure (some state bar associations and accountancy boards mandate partnerships rather than LLCs), or you and your partners prefer traditional partnership governance.

The Bottom Line

For the vast majority of businesses, an LLC is the superior choice. It offers stronger liability protection, more flexibility, broader availability, and the S-Corp tax election option. LLPs serve a narrower purpose — they are designed for multi-partner professional service firms where partnership structure is preferred or required by state licensing rules.
