Wound Care Practice Legal Structure: LLC vs S-Corp vs PC
Entity selection is one of the first decisions you'll make when starting a wound care practice, and one of the most consequential. Get it right and you protect your personal assets, optimize your tax position, and avoid credentialing complications. Get it wrong and you're re-filing paperwork, re-credentialing with payers, and explaining to an attorney why you've been operating under the wrong structure for two years.
Most entity guides are written for general businesses. Healthcare practices operate under different rules -- some states require specific entity types for clinical businesses, payer enrollment asks about your corporate structure, and the liability exposure in wound care makes this more than a tax exercise.

Why Entity Selection Matters for Healthcare
Healthcare businesses face four pressures that general businesses don't.
Liability protection is clinical, not just commercial. In wound care, you're managing chronic conditions where a missed assessment or documentation gap creates malpractice exposure. Your entity structure determines whether that exposure stays at the practice level or reaches your personal assets.
Tax treatment drives take-home pay. The difference between pass-through and corporate taxation can mean $10,000-$30,000 per year in a practice generating $200,000-$500,000 in net revenue.
State healthcare regulations restrict your options. Many states require healthcare providers to form professional entities -- PLLCs or PCs -- rather than standard LLCs. Form the wrong entity and you'll discover the problem when a payer rejects your credentialing application.
Payer credentialing depends on your entity type. Medicare enrollment (CMS-855B) asks for your business structure. Commercial payers verify it. If your entity type doesn't match state requirements, credentialing stalls -- and every day you can't bill is lost revenue.
LLC / PLLC: The Most Common Starting Point
The Limited Liability Company is where most wound care practices begin. Simple to form, flexible on taxation, and it provides the liability separation you need between personal and practice assets.
Standard LLC vs PLLC. In roughly half of US states, healthcare providers must form a Professional LLC (PLLC) rather than a standard LLC. The formation process is nearly identical, but a PLLC requires that all members hold the relevant professional license -- you can't have a non-clinician spouse as co-owner. New York, Texas, California, and Michigan are among the states requiring PLLCs. Check your state's requirements before filing.
Pass-through taxation by default. Practice income passes through to your personal return. No corporate tax return, no double taxation. The simplest structure and the right starting point for most new practices.
Flexibility to elect S-Corp taxation later. File Form 2553 with the IRS and your LLC is taxed as an S-Corp while retaining its LLC legal structure. No new entity needed. Start simple, optimize when income justifies the complexity.
Liability protection. An LLC separates your personal assets from practice liabilities. Important caveat: it does not protect you from your own clinical malpractice -- that's what malpractice insurance is for. The LLC protects you from business liabilities: vendor disputes, lease obligations, and partner liabilities.
Pros: Simple formation ($500-$1,500 with attorney-drafted operating agreement), low compliance burden, flexible ownership, and the S-Corp option when the math works.
Cons: Some payers take PLLCs less seriously than PCs (perception, not substance), and multi-provider practices may outgrow the structure in corporate practice of medicine states.
S-Corporation Election: When the Math Works
An S-Corp is not a separate entity type. It's a tax election on your existing LLC or corporation. This is the most misunderstood concept in small business structure.
How it works. As a standard LLC, all practice income is subject to self-employment tax (15.3% on the first $160,200 for 2026, 2.9% above that). With an S-Corp election, you pay yourself a reasonable salary (subject to payroll taxes), and remaining profit is distributed to you as an owner -- those distributions avoid self-employment tax.
When it makes sense. The savings become meaningful when net profit exceeds roughly $50,000-$60,000 after paying yourself a reasonable salary. Below that, payroll administration costs ($1,000-$3,000/year) eat into the savings.
Reasonable compensation is non-negotiable. The IRS scrutinizes S-Corp owner salaries, and healthcare professionals face higher scrutiny than most. You can't pay yourself $40,000 when wound care NPs in your market earn $110,000. Set your salary at a defensible market rate and document how you determined it.
Administrative overhead. Running payroll, quarterly tax returns, corporate minutes, and a separate S-Corp return (Form 1120-S). Budget $2,000-$5,000/year for a CPA who understands healthcare practice taxation.
Bottom line: Net $150,000+ after expenses and the S-Corp election likely saves $8,000-$15,000/year. Netting $40,000 in year one? Stick with the straight LLC and revisit when revenue grows.
Professional Corporation (PC)
A Professional Corporation is designed specifically for licensed professionals. In some states, it's the only option for physician-owned clinical practices.
When a PC is required. States with strong corporate practice of medicine doctrines -- California, New York, Texas, Illinois -- restrict non-physicians from owning entities that deliver medical services. Physician-owned wound care practices in these states typically must form as a PC. NP-owned practices usually form as PLLCs instead.
Liability protection specifics. A PC protects shareholders from business liabilities but does not shield you from your own malpractice. It does protect you from the malpractice of another provider in the practice.
Tax treatment. PCs can be taxed as C-Corps (double taxation -- avoid this) or elect S-Corp taxation. Most small wound care PCs elect S-Corp immediately.
Sole Proprietorship: Don't Do This
If you start seeing patients without forming an entity, you're operating as a sole proprietor whether you realize it or not.
Zero liability protection. Your house, savings, and retirement accounts are fully exposed to practice liabilities. Any business claim can reach everything you own.
The only acceptable timeline is zero. The moment you see your first patient, you should already have an LLC or PLLC in place. Formation takes days and costs $500-$1,500. There is no financial argument for delaying this.
State-Specific Considerations
Healthcare entity law is state law. Federal tax treatment is uniform, but the entity types available to you depend on your state's professional corporation statutes and scope of practice regulations.
Corporate practice of medicine doctrine. About a dozen states prohibit non-physician ownership of entities that deliver medical services. In strong CPOM states (California, Texas, New York), a non-physician cannot own a medical practice. NPs can still own wound care practices in these states, but the entity structure requires careful legal analysis.
Collaborating physician as co-owner. Your collaborating physician is not automatically a co-owner -- and in most cases, shouldn't be. The collaboration agreement and business ownership are separate legal relationships. Mixing them creates complications if the collaboration ends.
Multi-state practices. Treating patients across state lines requires registering as a foreign entity in each additional state. Treating patients in an unregistered state creates licensing and liability exposure.
Practical Decision Framework
The decision tree for most wound care practices is straightforward:
Solo NP or PA: PLLC (or LLC where your state allows it), pass-through taxation, elect S-Corp when net income exceeds $50,000-$60,000 after reasonable salary. This is the right structure for 80% of new wound care practices.
Physician-owned: PC in corporate practice of medicine states, LLC/PLLC in states without. Elect S-Corp from year one if you expect meaningful net income.
Multi-provider: LLC or PLLC with a detailed operating agreement covering profit distribution, management authority, buy-sell provisions, and departure terms. Confirm your state allows mixed-license ownership.

When to Bring in a Healthcare Attorney
A general business attorney can file your LLC. A healthcare attorney can tell you whether that LLC will survive its first payer audit.
Entity formation. Re-forming under a different entity type means new credentialing applications, new tax IDs, and new payer contracts. Budget $1,000-$2,500 for formation with a healthcare-specific attorney.
Collaborative practice agreements. If you're an NP in a collaborative practice state, your CPA defines your scope of practice and your supervising physician's obligations. This needs to reflect your actual practice model, not a downloaded template.
Anti-kickback safe harbor structure. Wound care referral relationships with SNFs, home health agencies, and physician offices must comply with the Anti-Kickback Statute and Stark Law. Fair market value compensation, written agreements, and compliant referral arrangements are federal requirements.
Partnership and operating agreements. Generic templates don't cover healthcare-specific issues like license loss provisions, malpractice claim allocation, or payer contract assignment rights. If you have co-owners, invest in a proper operating agreement.
Your entity structure is the foundation everything else builds on. Spend the money to get it right at formation -- the cost of fixing it later is always higher.
