Choosing the right entity structure for a med spa is more complicated than for most businesses — and the stakes are higher. Between corporate practice of medicine laws, medical director requirements, and the high profit margins that make tax optimization critical, getting the entity wrong can cost you $20,000–$80,000 per year in unnecessary taxes or, worse, put your license and business at legal risk. Here's how to think through the decision.
Why Med Spas Are Different
Most businesses can choose an entity structure based purely on tax efficiency. Med spas can't. In most states, the corporate practice of medicine doctrine restricts who can own a business that provides medical services. This means a non-physician entrepreneur can't simply form an LLC and start offering Botox, laser treatments, and IV therapy — even if they hire a medical director.
The rules vary dramatically by state. Some states (like California and Texas) strictly enforce the doctrine. Others (like Florida and Nevada) are more permissive. Your entity structure must comply with your state's rules, or you risk losing your license, facing fines, or having contracts voided.
The Three Common Structures
1. Physician-Owned Professional Corporation (PC) or PLLC
In strict corporate practice of medicine states, the medical services must be provided through an entity owned by a licensed physician. This is typically a Professional Corporation (PC) or Professional Limited Liability Company (PLLC).
How it works: The physician owns the PC/PLLC, which employs or contracts with other providers (NPs, PAs, RNs, aestheticians). All medical revenue flows through this entity.
Tax treatment: The PC can elect S-Corp taxation to avoid double taxation and optimize self-employment tax.
Limitation: Only licensed physicians can be owners — so if the business is a partnership between a physician and a non-physician entrepreneur, this structure alone won't work.
2. Management Company Model (MSO + PC)
This is the most common structure for med spas with non-physician investors or operators. It involves two entities:
Professional Corporation (PC): Owned by the physician, provides all medical services, and employs medical staff.
Management Services Organization (MSO): Owned by the non-physician entrepreneur (or jointly), provides all non-medical services — marketing, billing, HR, facilities, equipment, and administrative management. The MSO charges the PC a management fee (typically 15–30% of revenue or a flat monthly fee).
| PC (Physician-Owned) | MSO (Entrepreneur-Owned) | |
|---|---|---|
| Owns | Medical practice, provider relationships | Equipment, lease, brand, marketing |
| Revenue | Medical service fees | Management fees from PC |
| Employees | Physicians, NPs, PAs, medical staff | Front desk, admin, marketing, billing |
| Tax election | S-Corp recommended | S-Corp or LLC (depends on structure) |
| Key compliance | State medical board, practice of medicine laws | Arms-length management fee, no fee-splitting |
Critical compliance point: The management fee between the MSO and PC must be at arm's length — meaning it reflects fair market value for the services provided. Fee-splitting (where the MSO's fee is based on a percentage of medical revenue) is prohibited in many states. Structure the management agreement carefully with legal counsel who understands your state's rules.
3. Simple LLC or S-Corp (Permissive States)
In states that don't strictly enforce the corporate practice of medicine doctrine (or that have exceptions for certain aesthetic services), a med spa can sometimes operate as a single LLC or S-Corp — even if the owner isn't a physician. The medical director is hired or contracted, and all services flow through one entity.
This is simpler and cheaper to maintain, but it only works in permissive states and for services that fall outside strict medical practice definitions. Always confirm with a healthcare attorney before relying on this approach.
S-Corp Election: The Tax Multiplier
Regardless of which structural model you use, the S-Corp election is almost always beneficial for med spa owners with net income above $80,000. And for high-revenue med spas — which can easily generate $500K–$2M+ in owner profit — the savings are substantial.
Consider a med spa owner (physician or entrepreneur through the MSO) earning $600,000 in net income through the entity:
In the MSO model, both entities should generally be S-Corps — the physician's PC and the entrepreneur's MSO. This maximizes the salary-to-distribution split on both sides of the structure.
Multi-Location Considerations
Med spas expanding to multiple locations face additional complexity. Each new location may need its own PC (if the medical director is different) or can operate under the same PC if the same physician oversees all locations. The MSO can typically manage multiple locations under one entity.
From a tax perspective, multi-location med spas should evaluate:
Separate LLCs per location for liability isolation (similar to the restaurant holding company model).
Cost segregation studies on each buildout — leasehold improvements, medical equipment, and treatment room finishes all qualify for accelerated depreciation.
State tax nexus — if you operate in multiple states, you may have filing obligations in each state where you have a physical presence.
Common Mistakes
Ignoring corporate practice of medicine laws. The most dangerous mistake. Operating without proper structure in a strict state can result in loss of licensure, voided contracts, and criminal penalties. Always involve a healthcare attorney.
Setting management fees too high. If the MSO charges the PC 85% of revenue as a management fee, the IRS (and state medical boards) will see it as disguised profit-sharing. Keep fees reasonable and well-documented.
Skipping the S-Corp election. Med spa profits are high enough that the FICA savings from S-Corp taxation are substantial — often $20,000–$40,000+ per year.
Using one entity when you need two. Non-physician owners in strict states who try to run everything through a single LLC are creating legal risk, even if it "works" initially.

Med spa entity structure requires balancing three priorities: state regulatory compliance, liability protection, and tax efficiency. The right answer depends on your state's corporate practice of medicine rules, whether the owner is a physician, and how many locations you're operating. Get this decision right with proper legal and tax guidance upfront — restructuring later is expensive, disruptive, and sometimes not possible without closing and reopening entities.
