Limited liability partnership (LLP): What it is, how it works, and how to start one


Key takeaways

  • An LLP mixes partnership flexibility with limited liability, shielding partners from personal responsibility for each other's professional errors.
  • Primarily for licensed professionals, LLP eligibility, rules, and protections differ significantly from state to state.
  • LLPs offer pass-through taxation (avoiding corporate taxes) but require specific state registration and compliance steps to form.


The question isn't if you'll start a business, but how you'll structure it. With 54% of aspiring entrepreneurs eyeing a business launch this year, according to QuickBooks' Entrepreneurship in 2025 report, making the right choice is critical. 

This guide will unpack everything you need to know about LLPs, from understanding how they blend partnership flexibility with corporate-level liability protection to navigating the steps of formation.

What is an LLP

A Limited Liability Partnership (LLP) is a business structure that combines the operational flexibility of a traditional partnership with the limited liability protection typically associated with corporations. It is particularly well-suited for licensed professionals like lawyers, accountants, architects, and doctors who wish to collaborate while mitigating personal financial risk.

How does an LLP work? 

The magic of an LLP lies being flexible like a traditional partnership while offering limited liability. 

Gives you limited liability

An LLP allows professionals to collaborate and run a business together, but with an important difference—partners are not typically held personally liable for the mistakes or negligence of their fellow partners. This means if one partner makes a costly error, the others are usually protected, shielding their personal assets from potential lawsuits or debts.

Unlike a general partnership where all partners are jointly and severally liable, in an LLP, liability is generally limited to each partner's actions and investments. This protection is a major draw for professionals like lawyers, accountants, and doctors.

Has the structure of a partnership

Operationally, an LLP functions much like a general partnership. Partners agree on how to run the business, share profits and losses, and make decisions together. This is usually formalized in a partnership agreement, which outlines the roles, responsibilities, and profit-sharing arrangements of each partner.

Is a pass through entity

From a tax perspective, LLPs are typically pass-through entities. This means the business itself doesn't pay income tax. Instead, profits and losses are distributed to the partners, who then report them on their individual tax returns. This avoids the double taxation that corporations often face.

Limited liability partnership requirements

Establishing and operating an LLP involves meeting several specific legal, administrative, and professional prerequisites. These requirements primarily ensure legal recognition, regulatory compliance, and operational clarity for the partnership structure.

Here are the key requirements for forming and maintaining an LLP:

  • Meet state-specific eligibility criteria and file registration documents.
  • Ensure all partners possess the necessary professional licenses.
  • Appoint and maintain an in-state registered agent.
  • Register a unique business name compliant with state LLP naming rules.
  • Create a detailed partnership agreement for internal operations.
  • Obtain a federal EIN and any required state tax IDs.
  • Secure all necessary business licenses and permits (federal, state, local).
  • Acquire legally required insurance (liability, workers' compensation, etc.).
  • Comply with ongoing state requirements like annual reports and fees.

Fulfilling these requirements is crucial for establishing the LLP structure correctly and maintaining its limited liability protections. Because regulations vary significantly, thorough research of your specific state's laws and consultation with legal or business advisors is strongly advised.

LLP vs LP

While both LLPs and limited partnerships (LPs) are partnership structures, they diverge significantly in their liability distribution and management roles, catering to distinct business objectives.

Limited liability partnership (LLP)

In an LLP, all partners benefit from limited liability. This means each partner is primarily liable for their actions and is generally shielded from the negligence or misconduct of other partners, as well as the partnership's overall debts. 

This structure is particularly advantageous for professional service firms, such as legal or accounting practices, where partners seek to collaborate while mitigating individual financial risk.

Limited partnership (LP) 

Conversely, an LP features two tiers of partners: general partners and limited partners. General partners assume active management responsibilities and bear unlimited personal liability for the partnership's obligations. 

Limited partners, on the other hand, are passive investors who contribute capital but do not participate in management. Their liability is limited to their investment. This structure is commonly employed in investment vehicles, including real estate and venture capital funds.

LLP vs LLC

LLPs and limited liability companies (LLCs) are both popular business structures that offer limited liability, but they cater to different needs and have distinct characteristics.

Limited liability partnership (LLP)

An LLP is primarily designed for professionals, such as lawyers, accountants, or architects, who want to operate as a partnership while limiting their personal liability for the misconduct of their partners. In an LLP, partners are generally liable for their own actions and the actions of those they directly supervise, but not for the negligence or malpractice of other partners. This structure emphasizes professional collaboration and shared management among partners.

Limited liability company (LLC)

An LLC, on the other hand, is a more versatile business structure that can be used by a wide range of businesses, not just professional service firms.

LLCs offer limited liability to their members, protecting their personal assets from business debts and obligations. LLCs provide flexibility in management structure, allowing members to choose between member-managed or manager-managed operations. Furthermore, LLCs offer flexibility in taxation, allowing members to choose how they want the business to be taxed.



note icon If you anticipate needing external investment or a public offering, an LLC's flexibility in membership and ownership structure may be more advantageous than an LLP's strictly partnership-focused model.


5 advantages of limited liability partnerships

Forming a limited liability partnership (LLP) offers several compelling advantages, particularly for professionals seeking to collaborate while mitigating personal risk. Here's a look at the key benefits:

1. Protection through limited liability

One of the primary draws of an LLP is the significant liability protection it offers. Partners are generally shielded from personal responsibility for the business's debts and, crucially, for the negligence, malpractice, or misconduct of other partners. This shields their personal assets (like homes, cars, and savings) from lawsuits or creditor claims arising from their colleagues' actions or overall business liabilities they didn't directly cause. Liability is typically confined to a partner's own actions and their investment in the firm.

2. Simplified pass-through taxation

LLPs are typically treated as "pass-through" entities for tax purposes, which simplifies tax obligations considerably. The business itself does not pay corporate income tax. Instead, the partnership's profits and losses are "passed through" directly to the individual partners, who then report their share on their personal income tax returns and pay taxes at their individual rates. This structure avoids the "double taxation" often faced by traditional C corporations, where profits are taxed first at the corporate level and again when distributed to owners as dividends.

3. Collaborative management flexibility

Unlike some other business structures, an LLP allows for significant flexibility in how the business is managed. Generally, all partners in an LLP have the right to participate actively in the management and decision-making processes of the business. This facilitates collaborative control and a shared approach to running the firm, contrasting sharply with limited partnerships (LPs) where limited partners are typically passive investors with no management rights.

4. Enhanced professional credibility

Operating as an LLP can enhance a firm's professional image and credibility, especially in fields like law, accounting, architecture, and medicine where this structure is common and well-regarded. Adopting the LLP structure can signal a commitment to professional standards and stability, potentially building greater trust with clients, suppliers, and financial institutions. In some jurisdictions or professions, it may even be the standard or preferred entity type.

5. Customizable internal structure

LLPs offer partners considerable freedom in defining their internal operating rules and governance. Through a comprehensive partnership agreement, partners can tailor the structure to their specific needs. This agreement can precisely outline capital contributions, profit and loss distribution methods, partner responsibilities, voting rights, procedures for admitting new partners, and protocols for partner departures or dispute resolution, creating a bespoke operational framework.

Disadvantages of a limited liability partnership

While LLPs offer significant advantages, particularly for professionals, potential drawbacks and limitations should be considered before choosing this structure. 

Here are some potential disadvantages associated with LLPs:

  • State-specific restrictions and complexity: LLP formation rules, eligibility criteria, fees, and ongoing compliance requirements can vary significantly from state to state, potentially adding complexity, especially for firms operating in multiple jurisdictions.
  • Formation process and costs: Setting up an LLP involves administrative steps, mandatory state filing fees, potential costs associated with drafting a comprehensive partnership agreement, and, in some states (like New York), potentially expensive public notification requirements.
  • Partners remain liable for own actions: The key liability protection in an LLP shields partners from the professional errors or negligence of other partners. However, partners generally remain personally liable for their own malpractice or negligence, as well as potentially for business debts they have personally guaranteed.
  • Potential difficulties in raising capital: Compared to corporate structures or LLCs, the inherent partnership nature of an LLP may present challenges or be less appealing when seeking significant external equity investment.
  • Requirement for detailed partnership agreement: While allowing customization, the need for a thorough partnership agreement requires careful negotiation, drafting, and agreement among all partners on critical issues like governance, profit distribution, and exit strategies to prevent future disputes, often necessitating legal counsel.

Carefully weighing these potential disadvantages against the benefits, particularly in the context of your specific state's regulations and the long-term goals of the partnership, is essential. Consulting with legal and financial professionals is recommended to navigate these potential challenges effectively.

Examples of limited liability partnerships

Limited Liability Partnerships are typically utilized by businesses that provide licensed professional services, where collaboration among peers is common. The structure allows these professionals to operate as partners while managing the personal risk associated with the actions of other partners.

Here are common examples of businesses that frequently operate as LLPs:

  • Law firms: Perhaps the most classic example, where multiple attorneys practice together, sharing resources and profits while limiting personal liability for each other's legal advice or actions.
  • Accounting firms: Practices involving Certified Public Accountants (CPAs) offering services like auditing, tax preparation, and financial consulting often form LLPs.
  • Architectural practices: Firms where licensed architects collaborate on design projects frequently use the LLP structure.
  • Medical or dental groups: In states where permitted, groups of physicians, dentists, or other licensed healthcare providers may form LLPs to run their joint practices.
  • Other professional services: Depending on specific state laws regarding eligibility, other professional groups such as engineering firms, consulting agencies, or veterinary practices might also structure themselves as LLPs.

Essentially, any professional service group where partners hold individual licenses and want partnership flexibility combined with liability protection might consider the LLP structure. The key factor often depends on whether state statutes permit that specific profession to form an LLP.

Considerations for the limited liability partnership structure

While a limited liability partnership (LLP) offers numerous benefits, it's essential to carefully consider several factors before deciding if this structure is right for your business. 

Forming an LLP involves specific legal and operational requirements that you should thoroughly understand, including: 

  • State regulations: LLP laws vary significantly from state to state. You must research and comply with the specific regulations in the state where you plan to operate. This includes understanding filing requirements, fees, and ongoing compliance obligations.
  • Professional licensing: Some professions, such as law, accounting, and medicine, have specific licensing requirements for LLPs. Ensure that all partners meet the necessary licensing and regulatory standards.
  • Partnership agreement: A comprehensive partnership agreement is crucial. This document outlines the rights, responsibilities, and profit-sharing arrangements of each partner. It also addresses potential disputes, dissolution procedures, and other important aspects of the partnership.
  • Liability insurance: While LLPs offer limited liability, it's still advisable to obtain professional liability insurance. This can provide additional protection against potential lawsuits or claims.
  • Tax implications: Understand the tax implications of operating as an LLP. While LLPs offer pass-through taxation, it's essential to consult with a tax professional to ensure compliance with all applicable tax laws.
  • Business purpose: LLPs are typically best suited for professional service firms. Evaluate whether an LLP aligns with your business's specific purpose and goals.

While an LLP offers substantial benefits, it's imperative to conduct thorough research and seek professional advice before making a decision. 

Limited liability partnership taxes in detail 

LLP taxation in the U.S. centers on pass-through treatment, meaning income is taxed at the partner level, not within the LLP entity itself. This approach contrasts sharply with traditional C corporations.

Here's a brief overview:

  • Pass-through federal taxes: The LLP itself typically pays no federal income tax. All profits, losses, and deductions are passed directly to the partners.
  • Partner-level income tax: Partners include their share of the LLP's income on their personal tax returns (Form 1040) and pay taxes at their individual rates.
  • Self-employment taxes: Partners are generally liable for self-employment taxes (Social Security and Medicare) on their share of LLP earnings.
  • Avoids double taxation: Unlike C corporations, LLP income is usually taxed only once at the partner level, avoiding potential double taxation.
  • Comparison with S corps/LLCs: While S corps also pass-through income, rules regarding self-employment tax often differ. LLCs offer more tax flexibility, as they can sometimes elect corporate tax status, an option generally unavailable to LLPs.
  • State and local taxes: Remember that state and local income, franchise, or other business taxes also apply and vary by location.

In essence, LLPs offer simplified federal taxation compared to C corps, but partners must manage their individual income and self-employment tax obligations. Given the complexities, consulting a tax professional is strongly advised.

How to start an limited liability partnership in 10 steps

Forming a limited liability partnership (LLP) requires careful attention to specific steps to ensure legal compliance. Here's a guide to help you through the process.

Flow chart showing how to start an LLP

1. Verify qualification status

Some states limit the type of businesses that can form a limited liability partnership (LLP). For instance, states such as California, Nevada, and New York generally only permit specific licensed professionals, like attorneys, accountants, or architects, to establish LLPs. 

Other potential state limitations might dictate that all partners must be licensed in the same profession within that state. Because rules vary widely and can change, verify the current, specific limitations and eligibility requirements for LLPs in your state, usually through the Secretary of State's office, before spending valuable time and resources applying for LLP status.

2. Pick a name

If you decide to name your business anything other than your name, your state and/or county may require you to register a “Doing Business As” (DBA) name.

Your proposed business name must be distinguishable from other businesses in your state. Search your state’s Secretary of State office’s database to see the availability of your proposed business name. Some states also restrict certain words from being in your name. A list of these words can be also obtained through your Secretary of State office.

Be sure to check with the U.S. Patent and Trademark Office to make sure your name doesn’t violate any registered trademarks.

Some states may allow you to reserve a name during processing and before the adoption of a proposed name. Reservation terms vary from state to state, and the terms can be verified by your local Secretary of State office.

Most states require the inclusion of “Limited Liability Partnership,” “LLP” or another related abbreviation at the end of your fictitious business name.


note icon Don’t forget to check for available web domain names and social media handles— securing these assets now prevents future headaches and ensures consistent branding as your business grows.


3. Draft a limited liability partnership agreement

While not mandatory in all states, a limited liability partnership agreement is highly recommended. This agreement should define each partner’s role and responsibilities. It should detail the partners’ assets and liability limitations. The agreement should also outline capital contributions, distribution of profits and losses, buyout agreements, and rules for the addition of new partners.

4. Designate a registered agent

Most states require all business entities to maintain a registered agent in the state. The registered agent must be an individual or company authorized to conduct business in the state in which you applied for LLP status. The agent must have a physical address in the state.

If your business is physically located in the state to which you’re applying, the company may act as its own agent.


note icon When choosing your registered agent, consider a service that provides digital document management—his ensures you have instant, organized access to legal notices.


5. File a Certificate of Limited Liability Partnership

Whereas the drafting of an LLP agreement is optional, filing for a Certificate of Limited Liability Partnership (sometimes called a Certificate of Registration as a Limited Liability Partnership) is mandatory.

The Certificate of Limited Liability Partnership is a more generalized form than a Limited Liability Partnership Agreement. The application for the certificate requires the listing of your business name and address, the names and contact info of your partners, information on your registered agent, etc.

Filing fees range anywhere from $50 to $100.

6. Register for an Employer Identification Number

An Employer Identification Number (EIN) is a nine-digit number issued by the IRS to classify a business for tax purposes. Sometimes referred to as a “Federal Tax Identification Number,” an EIN is required to open business banking accounts, to hire employees, or to make business transactions.

To apply for an EIN, file an IRS Form SS-4.

7. Obtain a state ID number

In addition to an EIN, some states also require a state ID number.

Like the EIN, the state ID number helps classify a business for tax purposes. If required, they are available through your state’s Department of Revenue.

8. Obtain required licenses and permits

Federal, state, and local authorities require permits and/or licenses for specific companies to lawfully operate. These include occupational and trade licenses, zoning and health permits, as well as other requirements.

The U.S. Small Business Administration has a useful database with lists of federal and state business licenses and permits on its website. Information on required county and town permits can be found at your local County Business License Office or City Hall.


note icon When researching required permits, don't overlook "silent" regulations. Some local zoning ordinances, for example, might restrict client traffic or signage in unexpected ways.


9. Purchase required insurance

Some states require Limited Liability Partnerships to purchase specific insurance plans.

Some states require workers’ compensation insurance for all businesses applying for a limited liability partnership. Other states also require malpractice liability insurance for LLPs to satisfy potential claims. Proof of adequate assets to cover this liability may be substituted for insurance in select states.

For more information on insurance requirements for your state, contact your local Secretary of State office, or Department of Industrial Relations. The offices can also help you locate insurance providers in your state.

10. Manage publication requirements

A small number of states require businesses to publicize LLP formation. An example of this is New York’s publication requirement.

The state of New York requires a detailed notice of formation to be published in two newspapers in the county in which the LLP is located. The notice must detail your business’ name, formation date, location, its registered agent, and business description.

An Affidavit of Publication must then be acquired from the newspaper and sent to the Department of State office.

While this can be expensive and may sound arbitrary, keep in mind that failure to comply with your state’s publication requirement may result in the loss of liability protection.

Your Secretary of State office can inform you of any publication requirements in your state, and your local county clerk can direct you to the publications needed to fulfill this requirement.


Feel confident from day one

You're never too small, and it's never too soon to know you're on track for success.

Tools and resources to move forward with an LLP

The formation of a limited liability partnership (LLP) presents a valuable opportunity for professionals to collaborate and benefit from liability protection. 

However, navigating the complexities of state-level regulations and ensuring your business is set up correctly requires access to reliable tools and resources. To help you on this journey, consider the following:

  • State Secretary of State Office: The primary source for state-specific LLP regulations, filing requirements, and forms—each state has its own rules. 
  • Business formation attorneys: A legal professional specializing in business formation can provide personalized guidance.
  • Internal Revenue Service (IRS): The IRS website offers extensive information on LLPs' tax obligations, including how to obtain an Employer Identification Number (EIN)
  • U.S. Small Business Administration (SBA): The SBA provides resources on business licensing, permits, and general business guidance. 
  • U.S. Patent and Trademark Office (USPTO): If you are creating a unique business name, checking for trademark violations is important. w
  • Your local county business license office or City Hall: For local permits or zoning information.
