Choosing how to structure your private practice is one of those decisions that feels more complicated than it should be.
If you’re weighing LLC vs. C corp for private practice in California, you’re not looking for a one-size-fits-all answer. The right structure depends on your income level, your growth plans, and how much administrative overhead you’re willing to take on. Here’s what actually matters.
What is the Difference Between an LLC and a C Corp for a Therapy Practice?
An LLC (limited liability company) and a C corporation are both legal entities that separate your personal assets from your business, but they’re taxed very differently.
An LLC is a pass-through entity by default, meaning profits flow to your personal tax return and you pay taxes once. A C corp is a separate taxable entity – it pays corporate income tax on its profits, and then you pay personal income tax again when you take money out as salary or dividends. That double layer of taxation is the central reason most solo and small-group practice therapists don’t use a C corp structure.
The federal corporate tax rate is currently 21%, and California adds an 8.84% state corporate tax on top of that, with a minimum franchise tax of $800 per year regardless of revenue.
Can Therapists in California Even Form a Standard LLC or Corporation?
California has specific rules for licensed professionals, and therapists are included. Under California law, licensed mental health professionals – LCSWs, LPCs, MFTs, psychologists – cannot own a standard LLC or C corporation to deliver clinical services.
Instead, California requires licensed therapists to form a Professional Corporation (PC), specifically a Psychological Corporation or a Professional Psychotherapy Corporation, depending on license type. This is a critical distinction.
If you’re operating as a sole proprietor and want a formal business entity, your path leads to a professional corporation, not a general C corp or standard LLC. The California Secretary of State and your licensing board (the BBS for LCSWs, LPCs, and MFTs, or the BOP for psychologists) govern which structure you’re allowed to use.
How is a Professional Corporation Taxed in California Compared to an LLC?
A professional corporation in California is taxed at the same 8.84% state rate as a regular C corp, with the same $800 annual minimum franchise tax.
At the federal level, personal service corporations (which is the IRS classification most therapy professional corporations fall under) are taxed at a flat 21% rate with no graduated brackets. That flat rate is a meaningful disadvantage for small practices – a sole proprietor or single-member LLC taxed as a pass-through pays federal income tax at marginal rates that can be lower than 21% at moderate income levels.
For a therapist clearing $80,000 to $150,000 in net practice income, the pass-through structure of a sole proprietorship or LLC taxed as an S corporation typically produces a lower overall tax bill than a professional corporation taxed as a C corp.
What are the Tax Advantages of an LLC for a California Therapy Practice?
An LLC that elects to be taxed as an S corporation is the structure many private practice therapists use once their net income reaches a meaningful threshold – typically around $80,000 to $100,000 in annual net profit.
The S-corp election allows you to split income between a W-2 salary and distributions. Only the salary portion is subject to self-employment tax (15.3% on the first $176,100 of wages in 2025, then 2.9% above that).
Distributions skip self-employment tax entirely, which is where the savings come from. For a therapist netting $120,000 a year, paying yourself a reasonable salary of $70,000 and taking $50,000 as a distribution could save $7,000 to $9,000 in self-employment taxes annually, depending on your specific situation. California also charges an LLC a gross receipts fee on top of the $800 minimum franchise tax once revenue exceeds $250,000, so factor that in if your practice is growing quickly.
Running the numbers on your specific income is essential before electing S-corp status – you can use the S-corporation tax calculator to get a real estimate for your practice.
When Does a C Corp Structure Actually Make Sense for a Therapist?
A C corporation structure makes sense in a narrow set of circumstances that most private practice therapists don’t fit.
The situations where a C corp has genuine advantages include practices intending to raise outside investor capital (investors often require C corp structure), practices planning to offer equity-based compensation to employees or future partners, and high-revenue group practices where retaining earnings inside the entity at the 21% corporate rate is strategically preferable to distributing them and paying personal income tax at higher marginal rates.
For the vast majority of California therapists running solo or small group practices with income in the $80,000 to $400,000 range, a C corp or professional corporation taxed as a C corp is the more expensive, more administratively burdensome choice. Double taxation, California’s 8.84% corporate rate, and the $800 annual minimum franchise tax stack up fast.
What are the Liability Protections of an LLC vs a Professional Corporation for Therapists?
Both an LLC and a professional corporation offer personal liability protection for general business debts, meaning creditors typically can’t come after your personal assets for practice-related obligations. However, neither entity shields you from personal liability for your own professional malpractice.
As a licensed clinician, you remain personally liable for your clinical work regardless of business structure. That’s why malpractice insurance remains essential no matter which entity you form.
In California, a professional corporation adds a layer of protection by limiting the liability of one shareholder-clinician for the malpractice of another clinician in the same practice, which matters more as your group grows. An LLC does not provide that same shield between co-owners in a therapy context.
How Much Does it Cost to Maintain an LLC vs a Professional Corporation in California?
Both structures carry California’s $800 annual minimum franchise tax. An LLC also pays the gross receipts fee starting at $900 for revenue between $250,000 and $499,999, scaling up from there. A professional corporation pays the 8.84% state corporate tax rate rather than a gross receipts fee, which can be higher or lower depending on the practice’s profit margin.
On the federal side, an LLC taxed as an S corporation files Form 1120-S; a C corp or professional corporation taxed as a C corp files Form 1120. S-corp returns typically cost $700 to $1,500 to prepare; C-corp returns are generally more complex and run $1,200 to $3,000 or more annually.
Add payroll processing, annual statement of information filings, and registered agent fees, and the real annual cost of maintaining any formal entity in California is typically $1,500 to $4,000+, depending on structure and complexity.
What Structure do Most California Therapists Use in Private Practice?
Most California therapists in solo or small group private practice operate either as sole proprietors, as single-member LLCs (taxed as disregarded entities or S corporations), or as professional corporations taxed as S corporations once required by licensing rules. The professional corporation taxed as an S corp is effectively the therapist’s equivalent of the LLC S-corp election – it gets you liability separation, pass-through taxation, and the self-employment tax savings from a salary-plus-distribution split, while staying compliant with California’s professional licensing requirements.
If you’re earlier in your practice and not yet netting enough to justify entity costs, a sole proprietorship with solid malpractice insurance is a legitimate starting point. The decision to form a formal entity and elect S-corp status is usually worth revisiting annually as your income grows.
