How to Start a Professional Limited Liability Company (PLLC)

If you're a licensed professional, a standard LLC might not be an option for you. Instead, many states require doctors, attorneys, architects, engineers, accountants, and therapists to form a professional limited liability company (PLLC). A PLLC is not the same as a standard LLC, and that distinction matters both legally and for maintaining licensing compliance. Knowing how to start a PLLC correctly from the beginning keeps you compliant with your licensing board, protects your business operations, and sets you up for the right tax treatment.

This guide walks you through everything you need to know, from understanding what a PLLC is to completing each step of the formation process.

What Is a PLLC?

A PLLC is a state-authorized business structure that gives licensed professionals the liability protection of an LLC while also meeting profession-specific regulatory requirements. It functions similarly to a standard LLC in most ways, but the key difference lies in membership. In a PLLC, all or most members must hold the relevant professional license in the state where the business operates.

Common professions that form PLLCs include physicians, attorneys, dentists, architects, engineers, accountants, and therapists. If your profession requires a state license and you want to operate as an LLC, your state may require you to form a PLLC rather than a standard LLC.

But not all states use the PLLC designation. Some use terms like PC or professional limited liability partnership (PLLP). Before you file anything, check what your state specifically allows for your profession. The SBA business structure guide is a solid starting point for understanding how different entity types affect your liability and taxes.

PLLC vs. LLC: What's the Difference?

This table breaks down the core differences between a standard LLC and a PLLC across four key dimensions.

One common misconception is that forming a PLLC fully shields you from malpractice claims for your professional services. It does not. A PLLC generally protects you from liability caused by another member's professional errors, but you remain personally liable for your own malpractice. That is why malpractice insurance and other liability insurance remain essential regardless of your entity type.

If you are not a licensed professional and are simply looking for personal asset protection, you don't need a PLLC. See how to register a traditional LLC for a straightforward overview of the standard LLC formation process.

Do All States Allow PLLCs?

PLLC availability varies significantly by state, and the rules are not uniform. Some states, like California, do not recognize PLLCs at all, while others, like New York, allow PLLCs but impose specific requirements for certain professions. Other states may permit PLLCs for some licensed professions but require a professional corporation for others.

Before you file any formation documents, confirm two things: whether your state recognizes PLLCs, and whether your specific profession qualifies for a PLLC structure. Your Secretary of State's website and your professional licensing board are the right places for licensed individuals to check.

Before filing anything, confirm your state recognizes PLLCs for your profession.

Skipping this step can result in filing the wrong business entity type, which creates compliance problems down the road and may require you to dissolve and reform under the correct structure. Certain licensed professionals may not be able to form a PLLC in their home state.

How to Start a PLLC: Step-by-Step

The PLLC formation process involves more steps than a standard LLC, primarily due to the licensing requirements layered on top of the standard filing process. Here is what to expect; it's best to follow these steps in order.

Step 1: Confirm your state allows PLLCs for your profession. Check your state's Secretary of State website and your professional licensing board. Some states restrict certain professions to other entity types entirely.

Step 2: Verify pre-approval PLLC state requirements. Several states require you to obtain approval from your professional licensing board before you can file formation documents. This step varies widely, so contact your board directly to find out what is required of you upfront.

Step 3: Choose a compliant business name. Most states require a PLLC name to include "PLLC" or "Professional Limited Liability Company" in the official name. Your chosen name also cannot conflict with any existing registered business. Use your state's business name database to check availability before you commit to a name.

Step 4: Appoint a registered agent. A registered agent receives official legal documents on behalf of your business. The agent must have a physical street address in the state where you are forming your PLLC, not a P. O. box. You can serve as your own registered agent, hire a registered agent service, or designate another individual as long as they qualify.

Step 5: File articles of organization. This is the formal document that establishes your PLLC with your state. Filing fees typically range from $50 to $500, depending on where you file, and some states charge additional fees for PLLCs compared to standard LLCs. For a broader look at what formation costs to expect, see this LLC costs breakdown. Some states also require supplemental documentation specific to PLLCs, such as a certificate of good standing from your licensing board.

Step 6: Draft an operating agreement. Not every state legally requires a PLLC to have an operating agreement, but it's a best practice to draft one. A well-drafted operating agreement defines ownership percentages, member roles, internal rules, profit distribution, and what happens if a member loses their professional license. That last point is especially important for PLLCs, since a member losing their license can affect the entire entity's standing.

Step 7: Obtain an Employer Identification Number (EIN). An EIN is required to open a business bank account, hire employees, and file your business taxes. You can apply for an EIN through the IRS website at no cost, and the process is simple.

Step 8: Register with your professional licensing board. After your state formation is complete, most professionals must register with the relevant board to complete the PLLC application process. Ongoing license renewals for all members are typically required to maintain your PLLC's limited liability status, so build those renewal dates into your calendar from day one for tax purposes.

PLLC Tax Treatment: What to Expect

By default, a single-member PLLC is taxed as a sole proprietorship, and a multi-member PLLC is taxed as a partnership. Both are pass-through structures, meaning income flows to members' personal tax returns rather than being taxed at the entity level. Members also pay the 15.3% self-employment tax on their share of profits. The IRS guidance on LLC tax classification covers the default rules and available elections in detail.

PLLC members can elect to be taxed as an S corp or C corp using IRS Form 2553, Election by a Small Business Corporation, or IRS Form 8832, Entity Classification Election. Depending on your income level, an S corp election can, in particular, reduce your self-employment tax burden. To understand how those two structures compare, this article on LLC vs. S corp taxes breaks it down.

The right tax election depends on your net income, how you pay yourself, and your long-term financial goals. A tax professional can help you evaluate which option makes sense before your PLLC files its first return. 1-800Accountant's tax advisory team handles this kind of planning so you're covered throughout the year, not just at filing time.

Ongoing Compliance After Formation

The PLLC formation steps are just the beginning. Staying in good standing requires consistent attention to several recurring obligations:

• Annual reports: Most states require professional LLCs to file annual or biennial reports with the Secretary of State. Deadlines and fees vary, so it's essential to confirm your state's requirements.

• Professional license renewals: Every member must keep their individual license current. A lapsed license can jeopardize the entire PLLC's standing.

• Registered agent maintenance: Your registered agent must remain active and reachable at a valid in-state address.

• Operating agreement updates: If membership changes or a member loses their license, your PPLC operating agreement should be updated to reflect the new situation.

• Separate business banking and financial records: Commingling personal and business funds is one of the fastest ways to lose liability protection.

Failing to meet these obligations can result in your PLLC losing good standing or being administratively dissolved by the state. For a detailed look at ongoing entity compliance, see this article.

Keeping clean financial records from day one also makes tax filing significantly easier. Many licensed professionals underestimate how quickly bookkeeping falls behind in the early months of a new practice. 1-800Accountant's bookkeeping support is built for exactly that situation, giving you a clear financial picture without pulling you away from your clients.

Getting Your PLLC Off to the Right Start

Starting a PLLC involves more steps than a standard LLC, but for licensed professionals, it is often the right structure for both regulatory compliance and liability protection. Knowing how to start a PLLC correctly means understanding your state's rules, your licensing board's requirements, and your tax obligations from the beginning.
