Short answer: most dentists operate their practice through a professional entity — a professional corporation (PC) or professional LLC (PLLC), depending on state law — often with an S-corporation tax election layered on top for tax efficiency. The entity does two jobs: it helps separate business liability from your personal assets, and it shapes how you’re taxed. The right structure is state-specific, so it’s a decision to make with a CPA and attorney, not from a template.
What entity options do dentists have?
Because dentistry is a licensed profession, most states require practice ownership through a professional entity — commonly a professional corporation (PC) or professional limited liability company (PLLC) — rather than a plain LLC. On top of the legal entity sits a tax election: many practices elect S-corporation treatment for its payroll-tax advantages. The legal form and the tax election are two separate choices that work together.
| Structure | Nature | Note for dentists |
|---|---|---|
| Sole proprietor | No separate entity | Simplest; least separation of liability |
| PC / PLLC | Professional legal entity | Often required; separates business liability |
| S-corp election | A tax status, not an entity | Can cut payroll tax on profit above salary |
| C-corp | Separate taxpaying entity | Rare for practices; specific situations only |
How does entity choice affect taxes?
The biggest lever for many owners is the S-corp election. It lets profit above a reasonable salary pass through as distributions that generally avoid Social Security and Medicare tax. That can save meaningfully — but only if profit is high enough to outweigh the added payroll and compliance costs, and only with a defensible salary. We compare the trade-offs in S-corp vs. sole proprietor.

How does the practice building fit in?
Many owners hold real estate in a separate entity from the practice, so the property and the operating business aren’t exposed to each other’s risks — and so the building can be handled independently at a sale. That separation is a core reason entity planning and real-estate planning go hand in hand.
When should you revisit your structure?
Entity structure isn’t “set and forget.” Revisit it when profit grows, when you add partners or associates, when you buy real estate or a second location, or when tax law changes. Each of those can change whether your current structure is still optimal.
Frequently asked questions
For most dentists, a professional entity (PC or PLLC, depending on state law) with an S-corporation tax election is common, because it separates business liability and can reduce payroll taxes on profit above a reasonable salary. The best choice depends on your state, profit level, and goals, so decide it with a CPA and attorney.
No. A professional entity can help separate business liabilities from your personal assets, but it does not shield you from personal responsibility for your own clinical malpractice. That risk is addressed with malpractice (professional liability) insurance, not entity structure.
Often, once profit is high enough that the payroll-tax savings on distributions exceed the added costs and you can support a reasonable salary. It’s not automatically right for everyone — coordinate the decision with your CPA, and weigh how it interacts with retirement-plan contributions.
