PLLC vs PC for Physicians: Which Entity Is Right for Your Practice?

You finished residency to practice medicine, not to decode entity statutes. Yet one of the first decisions a new practice owner or 1099 physician faces is which legal entity to form, and the paperwork usually arrives with a confident recommendation and no explanation of what it costs you at tax time. PLLC or PC? The honest answer is that the entity name matters less than most people think. What actually moves your tax bill is the tax election you put on top of it. This guide walks through both, in plain terms, so you can have a sharper conversation with your tax team before anything gets filed.

What is the difference between a PLLC and a PC?

A PLLC is a professional limited liability company: the LLC form, restricted to licensed professionals. A PC is a professional corporation: the corporate form, again restricted to licensed professionals. Both are created under state law, and most states reserve them for licensed fields like medicine.

Here is the part the formation websites skip. Your legal entity and your tax classification are two separate questions. The entity is what you register with the state. The tax classification is how the IRS decides to tax that entity, and you often get to choose it. A physician can run the exact same practice as a PLLC or a PC and end up taxed in very different ways depending on the elections made. So when someone asks "PLLC or PC," the more useful question is "how do you want this taxed."

Keep that split in mind for everything below.

How is each entity actually taxed?

This is where the real money is, so it is worth slowing down.

A PLLC follows the default LLC rules. According to the IRS, "an LLC with only one member is treated as an entity disregarded as separate from its owner," and "a domestic LLC with at least two members is classified as a partnership for federal income tax purposes unless it files Form 8832 and affirmatively elects to be treated as a corporation." In plain terms: a one-physician PLLC is taxed on your own return, and a multi-owner PLLC is taxed as a partnership, unless you elect something else.

A PC is a corporation. For federal income tax, the IRS treats a corporation as "a separate taxpaying entity," which means by default a PC is a C corporation and files its own corporate return.

The C-corp default trap

Here is the trap that catches physicians who form a PC and stop there. A C corporation is taxed twice. As the IRS puts it, "the profit of a corporation is taxed to the corporation when earned, and then is taxed to the shareholders when distributed as dividends. This creates a double tax." The corporation pays a flat 21% federal rate on its profit under current law (Internal Revenue Code section 11(b): "the amount of the tax imposed by subsection (a) shall be 21 percent of taxable income"), and then you pay tax again when you take that money out as a dividend.

One historical footnote that still causes confusion: years ago, a "personal service corporation" like a medical PC faced a special, higher flat rate. The 2017 tax law removed that, so a physician PC taxed as a C corporation now pays the same flat 21% as any other C corporation. The double tax, not a penalty rate, is the issue to watch.

The election that changes the math

Either entity can ask to be taxed as an S corporation. An S corporation passes its income through to the owners and, in the IRS's words, "allows S corporations to avoid double taxation on the corporate income." That single election is usually what a physician actually wants, and it is available whether you started as a PLLC or a PC. We cover the S-corp decision in depth in our guide to the S-corp election for physicians.

So the practical hierarchy is: pick an entity your state allows, then choose the tax treatment that fits your income. The label on the door is the smaller decision.

PLLC vs PC: which should a physician choose?

For most solo physicians, the simpler entity is the PLLC, with an S-corp election added once the income justifies the payroll and bookkeeping it requires. A few things to weigh:

• State law first. Some states will not let a physician use a PLLC and require a professional corporation instead, and a handful do not recognize PLLCs at all. Your options may be narrower than this guide, so confirm what your state allows before you commit.

• Administrative load. A PC carries more corporate formality: bylaws, a board, minutes, annual meetings. A PLLC is generally lighter to maintain.

• Tax flexibility. Both can elect S-corp status, so neither locks you out of the most common physician tax move. The difference is mostly the upkeep around it.

• Ownership plans. If you expect partners, a group, or outside structure later, that can tilt the choice. Multi-owner physician groups have their own considerations, which we cover in Multi-Member LLC for Physicians. Some physicians also layer a physician holding company over the practice entity.

Does the right entity change by state?

Yes, and this is where national advice falls apart. Medicine is governed by a state-level idea called the corporate practice of medicine, which limits who may own a medical practice and in what form. The result is that the same physician could be required to use a professional corporation in one state, be free to use a PLLC in another, and find that a third does not offer a PLLC at all.

Because these rules are set by each state's corporate and licensing authorities rather than the IRS, we are not going to assert specifics for your state in a national guide. The pattern to take away is simple: confirm your entity options with your state before you assume the federal tax treatment is even available to you.

What does a PLLC or PC actually protect you from?

A common reason physicians form an entity is liability protection, so it is worth being precise about what the entity does and does not do.

An entity can shield you from business and contract liabilities: an office lease, a vendor dispute, debts the practice takes on. What it does not do is shield you from your own clinical malpractice. If a patient sues you for your own professional negligence, the entity is not a wall around your personal liability. That is exactly why physicians carry malpractice insurance regardless of whether they practice through a PLLC, a PC, or nothing at all.

In other words, treat the entity as a tax and business structure, not a malpractice shield. The liability questions, including how creditor protection differs between an LLC and a corporation in your state, are legal questions worth running by counsel rather than settling from a blog.

Picked the wrong entity? Here is How Physicians Fix It

Plenty of physicians come to us having already formed something that no longer fits. The good news is that the wrong entity is usually fixable, and the fix is often a tax election rather than a teardown.

• Elect S-corp status on what you already have. If the problem is the double tax inside a C-corp PC, or self employment tax on a sole proprietor PLLC, an S-corp election often solves it without changing your legal entity at all.

• Convert the entity. Where state law allows, a PLLC and a PC can be converted from one to the other. The availability and the steps are state specific, so check yours before you start.

• Mind the tax cost of unwinding a C corporation. Switching a profitable C-corp PC out of C-corp status is not free. An S corporation can owe tax at the entity level on "certain built in gains," and liquidating a C corporation can trigger its own tax. This is fact specific, so model it with your tax team before you move.

• Missed the S-election deadline? You may still qualify for relief. The S-corp election is generally due within 2 months and 15 days of the start of the tax year it should take effect. If you missed it, the IRS allows late election relief under Revenue Procedure 2013-30 when "less than 3 years and 75 days have passed since the effective date of the election" and you meet the other conditions, such as reasonable cause and consistent reporting. It is not automatic, but it rescues a lot of physicians who filed late.

  
  

The theme: do not panic and dissolve anything. Most wrong entity situations are repaired with a form, not a funeral.

A worked example: Dr. Park runs the numbers

Numbers make this concrete. Meet Dr. Elena Park, a hospitalist who earns $320,000 of net practice income as a 1099 physician. The figures below are illustrative for the 2026 tax year, and a physician's actual result depends on their own facts.

As a sole proprietor (a single member PLLC with no election), her net earnings are subject to self employment tax. The self employment tax rate is 15.3%, made up of 12.4% for Social Security and 2.9% for Medicare. The 12.4% Social Security portion only applies up to the 2026 wage base of $184,500, and there is an extra 0.9% Medicare tax on earnings above $200,000 for a single filer. Roughly:

• Social Security: 12.4% of $184,500 = about $22,878

• Medicare: 2.9% of her net SE earnings = about $8,570

• Additional Medicare: 0.9% on earnings above $200,000 = about $860

• Total: about $32,300 (half of the regular portion is deductible for income tax)

  
  

Now suppose her tax team has her elect S-corp status on the same PLLC and sets a reasonable salary of, for illustration, $200,000, with the remaining $120,000 taken as a distribution. Payroll taxes apply to the salary, not the distribution:

• Social Security: 12.4% capped at $184,500 = about $22,878

• Medicare: 2.9% of $200,000 = about $5,800

• The $120,000 distribution: no Social Security or Medicare tax

• Total: about $28,678

  
  

Here is the physician specific insight that generalist advice misses. Once Dr. Park is earning above the $184,500 Social Security cap, the Social Security tax is the same either way, because both stop at the cap. The S-corp's advantage at her income is the 2.9% (plus 0.9%) Medicare tax she avoids on the distribution, which is real but is closer to a few thousand dollars than the "cut your taxes in half" claims you see online. That saving also has to cover the cost of running payroll and the extra return, and her salary has to hold up as reasonable compensation, which is a facts and circumstances judgment, not a number you pick to minimize tax. The IRS is explicit that an S corporation "must pay reasonable compensation to a shareholder employee in return for services that the employee provides to the corporation before non-wage distributions may be made."

One more thing the entity choice does not fix: the qualified business income (QBI) deduction. Medicine is what the regulations call a specified service trade or business, "the provision of medical services by individuals such as physicians." For 2026, that deduction phases out across an income range and disappears entirely once taxable income passes the top of it: $553,500 for joint filers (the phase out starts at $403,500) or $276,750 for other filers (starting at $201,750). At $320,000, Dr. Park is above the line, so she gets no QBI deduction whether she is a PLLC or a PC. The entity label does not change that, because the limit follows the activity, not the structure.

FAQs

Is a PLLC the same as a PC?

 No. A PLLC is the LLC form for licensed professionals, and a PC is the corporate form. They are taxed differently by default, and either can elect S-corp status.

What are the disadvantages of a PLLC?

Mainly that some states restrict or do not offer it for physicians, and that without an S-corp election a profitable single member PLLC pays full self employment tax on all of its earnings.

Is a PC or an LLC better for a doctor?

 Neither is universally better. The right answer depends on your state's rules and the tax election you plan to make. For many solo physicians it is a PLLC with an S-corp election once income supports it.

Can you switch from a PC to a PLLC?

Often yes, where your state allows the conversion, but unwinding a C corporation can have tax consequences, so model it with your tax team first.
