1099 vs. W-2 in Dentistry: How to Classify Dentists and Hygienists Correctly
A hygienist finishes a temp shift and asks to return directly, bypass the staffing agency, and be paid on a 1099. An associate dentist is offered 35 percent of production plus a signing bonus, but the contract calls the dentist an independent contractor. A traveling specialist works in several offices through a separate company. All three may be called 1099 arrangements, yet they can represent very different legal and economic relationships.
The first mistake is treating W-2 and 1099 as two payment options. They are not. Worker classification comes first, and the tax form follows. The IRS examines behavioral control, financial control, and the nature of the relationship. The Department of Labor applies a separate economic reality analysis, and states can impose additional rules. A contract can call someone an independent contractor, but the label does not override how the relationship actually works.
For a dental practice, the fastest reality test is to ignore the labels and describe the workday. Who supplies the patients? Who sets the fees? Who schedules appointments? Who owns the chairs, imaging equipment, software, supplies, and instruments? Who provides the assistants and front office team? Who bills and collects? Who decides when and where the clinician works? Who bears meaningful business expenses and the possibility of profit or loss? The more those answers point back to the practice, the more the relationship begins to resemble employment.
Consider the conventional hygienist. The practice provides the operatory, equipment, sterilization system, records, software, supplies, schedule, billing, and patients. The hygienist exercises independent clinical judgment, but clinical autonomy is not the same as business independence. A licensed professional can make treatment decisions and still be an employee. The same principle applies to associate dentists.
That is why familiar shortcuts are unreliable. Working one day a week does not automatically create contractor status. Neither does working for several offices, owning instruments, forming an LLC, being paid a percentage of production, or simply asking to receive a 1099. Even a carefully drafted independent contractor agreement cannot transform an employee style relationship into an independent business.
A genuine contractor looks different. Picture a traveling periodontist who operates through a separate company, markets services to several unrelated practices, negotiates compensation, chooses which engagements to accept, carries professional liability insurance, controls meaningful aspects of scheduling, pays substantial business expenses, and has a real opportunity for profit or loss. That begins to look like one business selling services to another. The American Dental Association describes independent contractor dentists in similarly entrepreneurial terms, with meaningful control over schedule, fees, appointments, treatment planning, taxes, insurance, and business expenses.
Associate dentists occupy a grayer area than front office employees or conventional hygienists. A full time associate working a fixed schedule at offices chosen by the employer, treating patients supplied by the organization, using its staff, equipment, software, and supplies, receiving a large signing bonus, and accepting a long term commitment has many employee characteristics. Dentists can be legitimate independent contractors, but professional licensure and clinical judgment alone do not make them one. The question is whether the dentist is actually operating an independent business.
Money complicates the issue because both sides can prefer 1099 treatment. For the worker, a larger check with nothing withheld feels better than a smaller W-2 paycheck. Independent contractors may also have legitimate deductions, retirement planning opportunities, and sometimes useful S corporation strategies. But an S corporation is not a tax magic trick. The IRS requires shareholder employees to receive reasonable compensation for the services they perform.
The economics of an associate offer therefore deserve a wider lens. Thirty five percent as a W-2 employee and 35 percent as a 1099 contractor are not equivalent. The real comparison includes payroll taxes, health benefits, retirement contributions, malpractice coverage, continuing education, workers compensation, unemployment protection, accounting costs, administrative burden, and legitimate business deductions. A contractor assuming more cost and risk may reasonably expect higher compensation, but higher compensation cannot cure improper classification.
Practice owners have incentives too. Contractors can appear cheaper because the practice may avoid payroll taxes, unemployment taxes, workers compensation costs, benefits, and payroll administration. That financial incentive is one reason classification receives scrutiny. Regulators are not asking which arrangement is easier or less expensive. They are asking what the relationship really is.
Temporary staffing adds another layer. A hygienist may choose individual shifts through an app and still be an employee. Temporary work and independent contracting are different concepts. If a temp worker asks to bypass the agency, the practice should also review its staffing agreement for conversion fees or other restrictions. That is a contract issue, not evidence of contractor status.
California shows how quickly the analysis becomes state specific. For many workers, California begins with a presumption of employee status and applies its ABC test. The hiring entity generally must show that the worker is free from its control, performs work outside the usual course of the hiring business, and already operates an independently established business of the same nature. That second requirement creates an obvious challenge for conventional hygiene because hygiene is part of the ordinary business of a dental practice. Certain licensed dentists are instead evaluated under California’s more flexible Borello test. Dental hygienists are not included in that dentist specific exemption.
Federal policy is also moving. In February 2026, the Department of Labor proposed replacing its 2024 independent contractor rule with a streamlined economic reality approach emphasizing control and opportunity for profit or loss. As of August 2026, that proposal has not become final. The details may change, but the practical question remains remarkably stable. Is the clinician genuinely operating a business, or working economically inside someone else’s?
Malpractice adds another complication. Independent contractor status is not a liability shield. In the 2026 New York case Verbridge v. Deol, an endodontist’s independence was supported by control over scheduling and clinical care and little supervision from the practice owner. The court found the owner was not vicariously liable under those circumstances. In Nilsen v. Franklin Dental Health, however, a jury found the treating dentist was an independent contractor, yet the appellate court concluded the dental organization could still potentially face liability under an apparent agency theory because the patient sought care from the clinic and was assigned a dentist there. Tax classification, employment status, and malpractice liability are related, but they are not the same question.
Professional liability coverage therefore needs its own review. Regardless of W-2 or 1099 status, the practice should know whose policy covers the clinician, the limits, whether coverage is occurrence or claims made, who is responsible for tail coverage, and whether licensing board proceedings are included.
When someone says, “I want to be 1099,” resist answering the tax question first. Describe the relationship. If the practice supplies nearly everything, assigns the patients, collects the revenue, determines the fees, establishes the working hours, and expects an ongoing relationship, employee classification deserves serious consideration. If the clinician truly operates a separate enterprise, markets services broadly, negotiates engagements, invests in the business, bears meaningful expenses and risk, and retains substantial control, contractor treatment may be defensible.
When the facts are unclear, have an employment attorney familiar with the state’s law evaluate the arrangement and a CPA analyze the tax consequences. The IRS also provides Form SS-8 for requesting a federal worker status determination. Temp arrangements require review of the staffing contract, and malpractice questions belong with the carrier.
The simplest mental model is also the most useful. A legitimate independent contractor should look like another business doing business with your practice. If the only visible difference between your contractor and your employee is that one paycheck has taxes withheld and the other does not, the distinction may exist more on paper than in reality.
If the tax form disappeared, would the person working in your office still look like an independent business?
