I am not an attorney, and this is not legal advice. This article is for general educational purposes only. Entity rules for licensed professionals vary by state, by profession, and sometimes by ownership structure. Before forming your business, you should confirm the rules with your state licensing board, your attorney, and your CPA. For tax elections like S-corp treatment, you should also get individualized tax advice before deciding what makes

sense for your practice.

If you are launching a solo private practice, one of the first questions you will run into is this:

Should I form an LLC, a PLLC, or an S-corp?

And unfortunately, this is one of those topics where the internet loves to sound very confident while leaving out the part that actually matters.

Here is the first thing to know:

LLC and PLLC are legal entity types. S-corp is a tax election.

That means you are not really choosing between three equal things. You are choosing:

what legal structure you are allowed or advised to form, and
whether that entity should later elect S-corp taxation.

That distinction matters more than people think, especially for licensed solo providers.

What is an LLC?

An LLC, or limited liability company, is a legal business structure that can help separate the business from the owner personally.

In plain English: it is often the basic, flexible structure people think of when they start a business. For many business owners, it feels simple and straightforward, which is exactly why people gravitate toward it.

But for licensed professionals, that does not automatically mean it is the right choice.

What is a PLLC?

A PLLC, or professional limited liability company, is a special type of LLC used for licensed professions in states that allow it.

This is where things start getting more specific. If you are a therapist, psychologist, PT, OT, SLP, physician, NP, or another licensed provider, your state may expect you to form a professional entity rather than a standard LLC.

That is why this conversation is not just about preference. It is about compliance.

What is an S-corp?

An S-corp is not a type of company you form with your state. It is a tax election.

This is the part people get mixed up constantly. A provider might form an LLC or PLLC under state law, then later elect S-corp taxation for federal tax purposes.

So in real life, many solo providers are deciding between things like:

PLLC taxed in the default way, or
PLLC with S-corp taxation later.

That is a very different question than “Should I form an S-corp?”

Your State May Make This Decision for You

One of the biggest mistakes new solo providers make is assuming entity choice is mostly about taxes or personal preference. It usually is not.

For licensed professionals, state law often narrows the menu before you ever get to the tax conversation. Some states recognize the PLLC structure. Others do not. And even within the same state, the answer may depend on your profession and licensing board.

A practical way to think about it is this:

States that recognize PLLCs

If you are forming in one of the states below, your state recognizes the PLLC structure. That does not automatically mean every licensed provider must use one, but it does mean PLLC is part of the conversation and may be the appropriate route for some licensed solo practices.

PLLC-recognition states:

Arizona

Arkansas

Colorado

Florida

Idaho

Iowa

Kentucky

Maine

Massachusetts

Michigan

Minnesota

Mississippi

Montana

Nevada

New Hampshire

New York

North Carolina

North Dakota

Oklahoma

Pennsylvania

South Dakota

Tennessee

Texas

Utah

Vermont

Virginia

Washington

West Virginia

If you are in one of these states, the real-world question is often not “LLC or S-corp?” It is more like:

Should I form the PLLC now, then decide later whether an S-corp election makes sense?

That is a much smarter sequence.

States that generally do not recognize PLLCs

If your state is not on the PLLC list, that usually means PLLC is not a formation option there. In those states, licensed providers are more often looking at a professional corporation, another profession-specific entity, or in some cases a regular LLC if their profession and state rules allow it.

States that generally do not recognize PLLCs:

Alabama

Alaska

California

Connecticut

Delaware

Georgia

Hawaii

Illinois

Indiana

Kansas

Louisiana

Maryland

Missouri

Nebraska

New Jersey

New Mexico

Ohio

Oregon

Rhode Island

South Carolina

Wisconsin

Wyoming

If you are in one of these states, the better question is usually:

What professional entity does my state and licensing board expect me to use instead?

That may be a professional corporation, professional association, or another state-specific option.

States where the rules are especially profession-specific

And then there is the extra-fun category: states where the answer can vary a lot depending on the profession involved.

States where provider type really matters:California

Illinois

New Jersey

Ohio

Oregon

Georgia

Maryland

Missouri

Wisconsin

South Carolina

In these states, broad online advice gets even less useful. A structure that may work for one licensed profession may not be the best fit for another. That is why solo providers should be very careful about taking one-size-fits-all business advice from someone who does not understand professional practice setup.

What this means in real life

Here is the practical takeaway:

In PLLC states, solo providers often compare PLLC now versus PLLC plus S-corp election later.
In non-PLLC states, solo providers are often deciding between a professional corporation or other board-approved structure, with S-corp treatment considered separately if the tax math supports it.
In every state, profession-specific rules still matter.

Bottom line: for licensed providers, entity choice is usually a compliance decision first and a tax decision second.

Why people get excited about S-corp taxation

The reason S-corp comes up so much is taxes.

With a default single-member LLC setup, business income typically flows through to the owner personally. With S-corp taxation, the owner who works in the business generally must be paid wages, and additional profit may be taken as distributions instead of having everything treated the same way for employment-tax purposes.

That is where the potential tax savings conversation comes from.

But this is where people start acting like S-corp is a magic wand. It is not.

S-corp taxation can create savings in the right scenario, but it also creates more payroll, more compliance, more accounting complexity, and more administrative responsibility. So no, it is not automatically the best move the second you hang your shingle.

Why S-corp is not automatically the best move on day one

S-corp taxation can absolutely make sense in the right setup. But it also adds work.

For a lot of brand-new solo providers, especially those who are still getting licensed, credentialed, paneled, and paid consistently, the real answer is often:

Start with the right legal entity first. Revisit S-corp later when the profit is there and the admin is worth it.

That is not the flashy answer. It is just usually the sane one.

Too many providers get distracted by tax optimization before they have even built a clean business foundation. That is backwards.

A practical framework for new solo providers

If you are trying to make this decision without spiraling into a midnight Google rabbit hole, here is the practical order of operations.

1. Figure out what your state allows for your profession

Before anything else, confirm whether your state recognizes PLLCs and whether your profession can or must use one. If not, find out what your state requires instead.

2. Form the correct legal entity

This is the state-law step. You are choosing the structure that is compliant for your profession and location.

3. Build clean financial systems from the beginning

Open the business bank account. Keep bookkeeping clean. Do not treat the business like a weird side pocket of your personal checking account. That road leads to confusion, accountant irritation, and preventable mess.

4. Revisit S-corp when the numbers justify it

Once your revenue is stable and profits are high enough to justify extra payroll and accounting complexity, that is when it makes sense to ask your CPA whether an S-corp election is worth considering.

My practical take

For many brand-new solo providers, the best path is usually this:

Choose the correct entity for your profession and state first. Then look at S-corp later if and when the numbers justify it.

That means:

If your state recognizes PLLCs and your profession should use one, start there.
If your state does not recognize PLLCs, figure out the right professional entity alternative.
If your practice becomes consistently profitable, talk to your CPA about whether S-corp taxation is worth the extra compliance load.

This is one of those areas where “simple” advice online gets people in trouble. The cleanest answer is usually the least sexy one:

Be compliant first, then optimize.

Bottom line

If you are a new solo provider, here is the simplest cheat sheet:

LLC = legal entity
PLLC = professional legal entity available in some states for licensed professions
S-corp = tax election, not a state-formed entity

So no, you probably do not need to panic and form an S-corp on day one.

You do need to make sure you are using the right structure for your profession and your state, and you should absolutely get individualized legal and tax advice before finalizing anything.

Final thought

A lot of solo providers want the “best” structure right away. I get it. You want to set it up right from the beginning and avoid expensive mistakes.

But in most cases, the smartest path is not the fanciest one. It is the one that keeps you compliant, keeps your admin manageable, and gives you room to grow without creating unnecessary complexity too early.

That is usually the better long game.

Starting a private practice comes with a lot of administrative decisions, and entity setup is only one piece of the puzzle.
