In most states, a dentist cannot use a standard LLC to run a practice. The answer to whether a dentist can use an LLC is almost always no: you need a Professional Limited Liability Company (PLLC) or a Professional Corporation (PC), depending on the state. Roughly 30 states authorize PLLCs; the rest require a PC, allow a regular LLC, or use a different professional entity structure. Filing the wrong type will usually get bounced by the Secretary of State before your practice ever opens.
Why a Regular LLC Doesn’t Work for Dentistry
The reason sits in a legal principle called the corporate practice of dentistry doctrine. A business entity cannot hold a dental license, so most states refuse to let one practice dentistry or employ dentists in a way that lets business interests override clinical judgment.1U.S. House of Representatives Oversight Committee. Survey of State Laws Governing the Corporate Practice of Dentistry The concern is an outside investor prioritizing revenue over patient care.
In practice, this means your state will likely require every owner of a dental practice entity to hold an active dental license in that state. A standard LLC does not enforce that restriction. PLLCs and PCs do, which is why the law channels dentists into them. Try to form a plain LLC for dental services and the filing office will usually reject the application.
What a Dental PLLC Actually Protects You From
A PLLC is not a full shield. It protects you from two things: your business partner’s malpractice claims, and ordinary business debts like equipment leases or vendor contracts. If your associate is sued for a botched procedure, creditors cannot reach your personal assets to satisfy that judgment.
What it does not protect you from is your own clinical negligence. If you personally commit malpractice, the PLLC does nothing to insulate your house, savings, or other personal property from the claim. The same goes for any business loan you personally guaranteed. States demand that trade-off in exchange for letting professionals form liability-shielding entities. You stay personally on the hook for your own professional conduct, which is why malpractice insurance matters, and why many state dental boards require or strongly encourage it as a condition of licensure.
Who Can Own a Dental PLLC
The corporate practice doctrine does more than dictate entity type. It shapes who can hold equity, who can sit on the governing board, and who makes clinical decisions. In most doctrine states, non-dentist family members, outside investors, and management companies cannot hold ownership interests or voting shares in a dental PLLC.2Internal Revenue Service. Corporate Practice of Medicine The rules typically extend to board members and managers, who must also be licensed dentists in the state.
Penalties for violating these ownership restrictions vary by jurisdiction but can include substantial civil fines, revocation of the practice’s permit, and in some states, criminal prosecution for the unauthorized practice of dentistry. Even well-intentioned arrangements, like giving a spouse a small ownership stake for estate-planning reasons, can run afoul of these rules. If your state follows the doctrine, every equity holder needs a valid dental license. No exceptions.
What About DSOs?
Dental Service Organizations are the recognized workaround for investors who want economic exposure to dental practices without owning them. A licensed dentist owns the PLLC or PC that provides clinical care, and the DSO signs a management agreement to handle non-clinical functions like billing, marketing, staffing, and lease negotiations. The DSO earns a management fee rather than holding equity in the practice.
The line between a compliant DSO and an illegal one is clinical control. The DSO cannot dictate treatment plans, set patient volume quotas, choose diagnostic equipment, or interfere with clinical judgment. Some states prohibit percentage-based management fees because they create an incentive to push volume over quality. If you are considering a DSO arrangement, the management agreement needs careful legal review before signing.
How to Form a Dental PLLC
Formation runs on two tracks: state business filings and professional board registration. Skipping either leaves the entity incomplete.
Articles of Organization
You start by filing Articles of Organization, or a Certificate of Formation depending on your state’s terminology, with the Secretary of State. The document requires a professional purpose statement explicitly limiting the entity to the practice of dentistry. Most states also require you to list the names and license numbers of all founding members so the office can verify eligibility. You will need to designate a registered agent in your state to accept legal documents during business hours.
The practice name must include a professional designation, typically “Professional Limited Liability Company” or “PLLC.” Using an unauthorized abbreviation or omitting the designation will get your paperwork rejected. Filing fees generally range from $100 to $500, with online submission usually processing faster than mail. Turnaround times vary by state, from days to weeks.
Board of Dentistry Registration
After the Secretary of State approves your formation, most states require you to file a copy of the approved articles with the state Board of Dentistry or equivalent licensing authority. Some boards charge a separate registration fee. Skipping this step can lead to holds on license renewals or complications proving your practice’s legal status to insurers and hospital credentialing committees.
Employer Identification Number
Every dental PLLC needs an EIN from the IRS, even with no employees. Banks require it to open a business account, and you need it for tax filings. The fastest route is the IRS online application, which is free and issues the number immediately. You can also fax Form SS-4 and get the EIN back in about four business days, or mail it and wait roughly four weeks.3Internal Revenue Service. Employer Identification Number
How a PLLC Gets Taxed
The IRS does not recognize “LLC” or “PLLC” as a tax classification. It drops your entity into a default bucket based on membership. A single-member PLLC is a disregarded entity, with income and expenses flowing onto your personal Form 1040, usually on Schedule C. A multi-member PLLC is treated as a partnership, filing Form 1065 and issuing each member a Schedule K-1.4Internal Revenue Service. Limited Liability Company (LLC)
You can override the default. Filing Form 8832 elects C corporation treatment.5Internal Revenue Service. About Form 8832, Entity Classification Election Filing Form 2553 elects S corporation treatment, which is the more common move for a profitable dental practice.
The S Corporation Election
Under default pass-through treatment, every dollar of net profit is subject to self-employment tax at 15.3%, broken down as 12.4% Social Security on earnings up to $184,500 in 2026 and 2.9% Medicare on all earnings.6Social Security Administration. Contribution and Benefit Base An S-Corp election splits your take into two streams: a reasonable salary subject to payroll taxes, and a distribution that is not subject to self-employment tax. On a $300,000 practice with a $150,000 salary, only the salary portion gets hit with payroll taxes.
The IRS expects that salary to reflect what comparable dentists actually earn in similar roles and geographic areas.7Internal Revenue Service. S Corporation Employees, Shareholders and Corporate Officers Setting it artificially low to maximize distributions is a common audit trigger. The savings typically start making sense once profits exceed roughly $100,000, below which the cost of running payroll and filing a corporate return may wash out the benefit.
File Form 2553 no later than two months and 15 days after the beginning of the tax year you want the election to take effect. The entity must have no more than 100 shareholders, all shareholders must be individuals or certain qualifying trusts and tax-exempt organizations, and the entity can have only one class of stock.8Office of the Law Revision Counsel. 26 USC 1361 – S Corporation Defined A typical dental PLLC meets these easily.
The 199A Deduction
Pass-through dental practices, whether on default treatment or an S-Corp election, may qualify for the Section 199A qualified business income deduction of up to 20% of qualified business income. Dentistry is a “specified service trade or business” under the statute because it involves health services.9Office of the Law Revision Counsel. 26 USC 199A – Qualified Business Income That label triggers an income-based phase-out: once taxable income exceeds a threshold (originally $157,500 for single filers and $315,000 for joint filers, adjusted annually), the deduction shrinks and eventually disappears. Section 199A was originally scheduled to expire after 2025, so check with a tax advisor on whether it still applies for your tax year.
Keeping the PLLC in Good Standing
Forming the PLLC is the start of your compliance obligations, not the end. Most states require annual or biennial reports confirming the entity is still active and the contact information is current. Fees range from about $20 to over $500. Falling behind does not just generate late fees. It can lead to administrative dissolution, where the state revokes your entity’s legal existence.
Dissolution is a serious problem. Your liability shield evaporates the moment the entity stops existing, exposing personal assets to business liabilities. Financial institutions may freeze business accounts or demand personal guarantees on existing credit lines. Reinstatement usually requires paying all back fees, filing every missed report, and paying penalties that can run into the thousands.
Keep your dental board registration current too. Many boards require notification of changes to ownership structure, office locations, or entity name. Your professional license renewal and your entity’s good standing run on separate tracks, and letting either lapse can cascade into problems with the other. A compliance calendar that tracks both sets of deadlines is worth building before you need it.
