PLLC vs PC for Doctors: Which Entity Structure Saves You More?

Most physicians get this question answered by their attorney, not their CPA. That’s a problem. Attorneys know how to form entities. They don’t always know how each one gets taxed — and for physicians, that distinction can mean $10,000 or more per year.

Here’s the short answer: for federal taxes, a PLLC and a PC are identical. Both can elect S-Corp status. Both split income between salary and distributions. The real differences are state law, liability nuance, and ownership flexibility. If you’re choosing between the two for your medical practice, check your state rules first, then worry about taxes second. This physician tax planning guide explains the broader picture.

The PLLC vs PC decision for doctors comes down to where you practice — not which one saves more money.

What’s the difference between a PLLC and a PC for doctors?

A PLLC (Professional Limited Liability Company) and a PC (Professional Corporation) are both entity types designed for licensed professionals like physicians. The tax difference? There isn’t one. Both can elect S-Corp status with the IRS, which means the same salary/distribution split and the same potential for FICA savings on income above your reasonable salary. The real differences are liability protection, state formation rules, and ownership flexibility. About half of states require physicians to use a PC; the rest allow PLLCs.

Key Takeaways

• For tax purposes, PLLC and PC are identical — Both can elect S-Corp or be taxed as a disregarded entity, producing the same federal tax outcomes
• State law determines which you can form — About 20–25 states require physicians to use a PC; Texas allows a PLLC or Professional Association (PA)
• Liability protection differs slightly — PLLCs generally offer stronger protection for non-malpractice claims like contract disputes and business debts
• The S-Corp election is what actually saves money — the entity type is the wrapper; the tax election is the engine
• Switching entity types later is possible — but it triggers tax events, so getting it right at formation matters

PLLC vs PC — Side-by-Side Comparison

Formation cost is similar between the two, with PC filing fees running slightly higher in some states. Ownership is the same — both typically require all owners to hold the same professional license as the business. Governance is where they diverge: PLLCs use an Operating Agreement, PCs use Bylaws and a Shareholder Agreement. PCs require more corporate formalities, including annual meetings and minutes, which adds a small ongoing compliance burden. Tax treatment at the default level differs — PLLCs default to pass-through taxation, while PCs default to C-Corp taxation (a major problem if you don’t elect out of it). Both correct this with a Form 2553 S-Corp election.

Which States Require a PC for Physicians?

State law governs professional entities. About 20–25 states require physicians to form a PC rather than a PLLC. The rest allow PLLCs, though terminology varies.

States that generally require a PC for physicians: California, Florida (PA), Georgia, Illinois, Michigan, New Jersey, New York, Ohio, Pennsylvania, Virginia

States that generally allow a PLLC for physicians: Arizona, Colorado, Delaware, Indiana, Minnesota, Nevada, North Carolina, Oregon, Washington, Wisconsin

Texas — its own category: Texas doesn’t use the term “PLLC” for licensed professionals in the traditional sense. Physicians in Texas can form either a Professional Association (PA) — which functions like a PC — or a Professional Limited Liability Company (PLLC) under the Texas Business Organizations Code. Both are valid. Both can elect S-Corp status.

This list is representative, not exhaustive. State medical boards update these rules, and multi-state practices add complexity. Always verify with your state’s medical licensing board before forming an entity.

SDO works with physicians in Texas and across multiple states — so we’re familiar with the variations that catch people off guard.

How the S-Corp Election Makes the Entity Type Irrelevant for Taxes

The entity type (PLLC or PC) is the legal wrapper. The S-Corp election is the engine.

What Form 2553 does: It tells the IRS to tax your entity as an S-Corporation instead of as a C-Corp (for PCs) or as a sole proprietorship/partnership (for PLLCs). With S-Corp status, your practice’s net income splits into two categories:

1. W-2 salary — subject to full FICA taxes (15.3% on the first $184,500 in 2026, then 2.9% Medicare above that)
2. Distributions — not subject to FICA taxes

The deadline: You must file Form 2553 within 75 days of entity formation for it to apply in the current tax year. For an existing entity, you file by March 15 to take effect for that calendar year.

Illustrative math: A physician earns $400,000 in net practice income. She sets a reasonable W-2 salary of $150,000 and takes $250,000 as S-Corp distributions. The $250,000 in distributions avoids FICA taxes entirely.

For a physician in this range, the S-Corp election can reduce FICA taxes by $10,000–$20,000+ annually depending on income level and salary determination. These are illustrative numbers — actual results depend on your specific income, reasonable compensation analysis, and state taxes.

The S-Corp tax calculator shows how these numbers work for different income levels. See the full LLC vs S-Corp comparison for a deeper breakdown.

The key point: this FICA savings opportunity is available to both PLLCs and PCs. The entity type doesn’t change the math.

When to Choose PLLC Over PC (and Vice Versa)

Choose a PC if: – Your state requires it for physicians (check first — this ends the decision) – You’re forming in a state where PLLCs for licensed professionals aren’t clearly authorized – Your practice will eventually seek outside investment from a VC or investor who prefers corporate structure

Choose a PLLC if: – Your state permits it and you want lighter governance requirements – You want maximum flexibility in allocating profits and losses among owners – You’re a solo physician without plans to bring on non-physician investors

Multi-state practices: This gets complicated fast. Each state where you practice has its own rules. A PLLC formed in Texas may need to register as a foreign entity in other states — and some states won’t recognize a foreign PLLC for professional services. A PC may face the same friction. Get state-specific advice before expanding across state lines.

Converting later: A PLLC can convert to a PC and vice versa. But the conversion is treated as a liquidation of the old entity and formation of a new one for tax purposes. That means potential recognition of built-up gains. Getting the structure right at formation is cheaper than fixing it later.

Formation Checklist for Medical PLLCs and PCs

Use this list when forming your medical entity. It applies to both PLLCs and PCs — with notes where they differ.

1. Choose entity type based on your state’s requirements. Confirm with your state’s Secretary of State and medical licensing board.
2. File Articles of Organization (PLLC) or Articles of Incorporation (PC) with your Secretary of State. Filing fees range from $50–$800 depending on state.
3. Obtain your EIN from the IRS. Apply at IRS.gov — takes about 15 minutes and you get it immediately.
4. Draft your Operating Agreement (PLLC) or Bylaws and Shareholder Agreement (PC). Don’t skip this step — it governs how decisions get made and what happens if an owner exits.
5. File Form 2553 for S-Corp election within 75 days of formation. Miss this window and you wait until next year. See the full S-Corp election guide for instructions.
6. Open a dedicated business bank account. Keep practice money strictly separate from personal finances.
7. Set up payroll. S-Corp owners must pay themselves a reasonable W-2 salary. No payroll means the IRS can reclassify distributions as wages and assess back taxes and penalties.
8. Register with your state medical licensing board if required. Some states require professional entities to register separately from the business formation filing.
9. Get a Certificate of Authority for any state you practice in outside your home state. Every state where you earn professional income may require foreign qualification.

Frequently Asked Questions

Can a PLLC and a PC both elect S-Corp status?

Yes. The S-Corp election via Form 2553 is available to both entity types. Once elected, both are taxed identically at the federal level — salary plus distributions, with FICA applying only to the salary portion.

Can non-physicians own a medical PLLC or PC?

Generally, no. Most states require all owners of a professional entity to hold the same license as the business’s profession. Some states allow a small percentage of non-professional ownership, but this varies. Check your state’s specific rules before bringing on any non-physician investors or business partners.

Which is cheaper to maintain — a PLLC or a PC?

PLLCs tend to run slightly cheaper over time. PCs require more formal governance: annual shareholder meetings, meeting minutes, and resolutions. Both require annual state report filings. The cost difference is modest — typically a few hundred dollars annually — but PLLCs have less administrative overhead.

Can I convert from a PC to a PLLC later?

Yes, but it’s not free. The IRS treats a conversion as a liquidation of the old entity and formation of a new one. That can trigger recognition of any built-up gains in the business. It’s doable, but the tax event makes it more expensive than getting the structure right at formation.

Does a PLLC protect me from malpractice lawsuits?

No entity fully shields you from professional malpractice liability. A PLLC and a PC both protect you from other owners’ malpractice claims, but not your own. Your personal assets remain exposed for your own clinical negligence. Malpractice insurance — not entity structure — is the real protection here. Entity structure does protect you from non-malpractice claims like business debts and contract disputes.

Can doctors operate as sole proprietors without an entity?

Yes, legally. But it leaves you personally liable for all business obligations, and you lose the S-Corp election opportunity. As a sole proprietor, all net income is subject to self-employment tax. For physicians earning $200,000 or more, this typically costs $10,000–$25,000+ more in self-employment taxes annually compared to an S-Corp. The entity and the election together create the tax savings.

Get Your Entity Structure Right from Day One

The PLLC vs PC decision is one part of a larger picture. SDO analyzes physician entity structures for practices in Texas and across multiple states — from initial formation to S-Corp election setup and ongoing S-Corp tax services.

Getting the structure wrong at formation means paying to fix it later. Getting the S-Corp election wrong means overpaying in FICA taxes every year until you correct it.

If you’re starting a practice, converting from a sole proprietorship, or unsure whether your current structure is optimized, we can help you assess the numbers.
