Should a Dental Associate Be 1099 or W-2? NJ and NY Rules

By Spiro Leunes, CPA | CEO, MRL Advisory Group, New Jersey and New York Dental CPAs

Reviewed September 2026. Worker classification rules change frequently, and the rules described below may not be the rules in effect when you read this.

This is one of the questions I am asked most often, by practice owners and by associates. Should the associate be a 1099 contractor or a W-2 employee?

The honest answer is that it is not a choice either party gets to make. Classification is determined by how the practice and the dentist actually work together. A practice does not create contractor status by putting the words "independent contractor" into an agreement, and a dentist does not become one by forming an entity or by being paid on collections.

That surprises people, because the decision usually gets made for practical reasons. The owner wants to hold down payroll cost. The associate has heard that 1099 income comes with better write-offs. Both instincts are reasonable. Neither one answers the question.

When the classification is wrong, the cost arrives all at once: back payroll taxes, penalties and interest, unemployment and workers compensation assessments, and potential wage claims. On the associate's side it arrives as a tax bill nobody planned for.

One thing I want to be clear about before we go further. Classification itself is a legal determination, and I am a CPA, not an attorney. What I can tell you is what the tests look at, what the arrangements I see in New Jersey and New York actually look like, and what each option costs in real dollars. The determination belongs with your employment counsel.

1. What the Two Labels Actually Mean

A W-2 employee is on the practice's payroll. The practice withholds income and payroll taxes, pays its share of payroll taxes, and generally carries unemployment and workers compensation.

A 1099 contractor is running a business. That dentist handles quarterly estimated taxes, self-employment tax, professional expenses, and the financial risk that comes with working independently.

How someone is paid does not decide which one they are. A W-2 associate can earn a salary, a daily guarantee, a percentage of collections, or a production bonus. A contractor can be paid the same ways. I covered the design of those models in how to structure dental associate compensation and what associate dentists should actually be paid.

The entity does not decide it either. An LLC or professional corporation may make good sense for a dentist genuinely running an independent business, and either can elect S corporation treatment, which I compared in S corporation versus LLC for dental practices. If you practice in both states, note that New Jersey dentists commonly use an LLC while New York requires a PLLC or professional corporation. Either way, forming the entity does not change the classification.

2. There Is More Than One Test

Most owners think of this as one determination. It is really several, applied by different agencies, and they do not always reach the same answer.

Who is looking	What they apply	What it affects
IRS	Behavioral control, financial control, and the overall relationship	Federal withholding, FICA, FUTA
U.S. Department of Labor	Whether the worker is economically dependent on the practice	Minimum wage and overtime, which matters more for staff than for associate dentists
New Jersey Department of Labor	The ABC test	Unemployment, temporary disability, and state wage claims
New York Department of Labor	Direction and control	Unemployment insurance and related obligations

An arrangement can clear the federal test and still fail in New Jersey. That is the part practices miss most often, and it is why "my accountant said it was fine" and "the state disagreed" can both be true statements about the same associate.

3. What the IRS Actually Looks At

The IRS looks at the whole relationship rather than the paperwork. The question underneath it is simple. Is this dentist running an independent business, or working inside the practice's business?

Points toward employee	Points toward contractor
The practice sets the days, hours and schedule	The dentist works for several unrelated practices and markets to the public
The practice assigns patients, operatories, staff and workflow	The dentist can make or lose money on his or her own business decisions
The associate uses the practice's facilities, equipment, supplies, front desk and billing	The dentist has real money invested and carries real business expenses
The arrangement is ongoing and part of normal patient care	The engagement is defined, limited, or genuinely independent
The practice directs how the work gets done day to day	The dentist controls the business side and is not dependent on one office

No single factor decides it, and it is not a matter of counting boxes. But in the typical associate arrangement I see, with set days, the practice's patients, the practice's team and equipment, and the associate built into the schedule, the facts line up on the employee side.

4. Clinical Independence Is Not the Same as Running a Business

This is the point that trips up more dentists than any other, and I hear it in almost every one of these conversations.

Every licensed dentist exercises clinical judgment. That is what practicing dentistry is. But deciding how to treat a patient is a different thing from running a business. An associate can have complete clinical discretion while working in an office that controls the schedule, the patient flow, the staff, the equipment, the fees and the billing.

If clinical autonomy by itself made someone a contractor, almost no licensed professional anywhere would ever be an employee.

5. The Explanations I Hear Most Often

"The agreement says independent contractor." The agreement is one document among many. When the day to day facts look like employment, the label generally does not carry the day.

"We pay 30 percent of collections." That is a compensation model, and it is one of the most common in dentistry. Employees are paid that way every day.

"The associate has an LLC." That affects the associate's own filings. It does not answer the classification question.

"It is only two days a week." Part-time employees are employees.

"We do not offer benefits." One fact among many, and rarely the deciding one.

"The associate asked for 1099." Preference does not control it. A dentist can agree to 1099 treatment in the spring and file for unemployment in the fall, and the state will reach its own conclusion regardless of what either party wanted.

6. When W-2 Fits

Picture the arrangement I see most often. The associate works Monday through Thursday, treats patients the office schedules, uses the practice's chairs and assistants, is paid on collections, follows the office's systems, and is expected to stay. That dentist may have wide clinical latitude and still be working inside someone else's business.

W-2 status works perfectly well with collections-based pay. You can still build incentives around production, collections, new patients or specialty procedures, and I would argue the plan is easier to administer on payroll than off it.

Whether the practice can support an associate at all is a separate calculation, and it comes first. I walked through the capacity, collections and overhead questions in when to hire a dental associate.

7. When 1099 Can Work

Contractor treatment is more likely to hold up where the dentist is genuinely running an independent business. Temporary coverage for a defined stretch. A specialist who independently serves several offices. A clinician who controls the business terms and has real exposure to profit and loss.

Where practices do use 1099 treatment, the facts that tend to support it are built while the arrangement is running, not reconstructed after a notice arrives. A defined scope and dates rather than an open-ended arrangement. The dentist invoicing the practice rather than being run on a payroll-style cycle. The dentist's own malpractice coverage, with the certificate on file. Evidence the dentist works elsewhere. Forms 1099-NEC filed every year without gaps. No participation in the practice's benefit plans. And consistent treatment of clinicians doing the same work, which is the one practices most often get wrong.

A regular associate position with the payroll obligations simply moved onto the dentist does not tend to survive any of the tests.

8. Run the Numbers Before Anyone Signs

This is the part I can actually help with, and in my experience it changes the conversation more than the legal analysis does.

Associates hear a higher percentage and assume a 1099 is worth more. Owners hear payroll tax savings and assume the same thing in reverse. Both are looking at one line of a longer calculation.

Take an associate collecting $600,000 a year, offered 30 percent as a W-2 or 35 percent as a 1099. That five-point spread looks decisive until you finish the math.

	W-2 at 30%	1099 at 35%
Gross compensation	$180,000	$210,000
Employment taxes paid by the dentist	Roughly $13,800	Roughly $28,500
Malpractice coverage	Typically the practice	Roughly $8,000
Approximate net before income tax	About $166,200	About $173,500

The numbers are illustrative and they move every year with the Social Security wage base, the associate's other income and what the practice actually provides. But the shape holds. A five-point premium narrows to something much smaller once the full self-employment tax and unreimbursed expenses come out, and that is before retirement contributions, health coverage and unpaid time off.

One item surprises nearly every associate I explain it to. Dentistry is a specified service business for the qualified business income deduction, and that deduction phases out completely above the income thresholds. A well-paid associate counting on 20 percent off the top for going 1099 may get nothing at all. I covered the related planning in how dentists should pay themselves.

On the practice side there is a second cost almost nobody prices. Retirement plan coverage and nondiscrimination testing depend on an accurate count of who your employees are. If a dentist treated as a contractor is later determined to be an employee, the plan can fail testing for those years. That correction can cost considerably more than the payroll taxes that were avoided, and several plan rules changed for 2026, which I covered in 2026 dental tax planning.

One more item to raise with counsel before the agreement is signed. Many associate agreements deduct lab fees, remakes or chargebacks from compensation. Both states restrict what may be taken out of an employee's wages, so a term that is routine in a contractor arrangement may not work the same way on payroll.

9. New Jersey Is the Stricter State

New Jersey starts from the assumption that a worker is an employee. To treat a dentist as a contractor, the practice has to satisfy all three parts of what the state calls the ABC test.

A. The dentist is free from the practice's control and direction, on paper and in practice.

B. The services are outside the usual course of the practice's business, or performed somewhere other than the practice's locations.

C. The dentist is genuinely engaged in an independently established business.

All three. Missing any one of them generally means employee treatment for the New Jersey programs that use the test.

For a normal associate, B is the hard one, and I would not expect most arrangements to get past it. Treating patients is what the practice does, and it happens in the practice's office. Calling the dentist a contractor, paying on collections, or paying an LLC does not change either of those facts.

The test also reaches past unemployment. New Jersey courts have applied it to state wage claims as well, which means a classification chosen for payroll reasons can resurface later as a wage dispute. The state has also sharpened enforcement over the last several years, adding stop-work authority, penalties aimed specifically at misclassification, public listing of violators, and in some circumstances liability that reaches owners personally.

None of that means every New Jersey dentist paid on a 1099 is misclassified. A truly independent specialist or a temporary clinician can present very different facts.

10. New York Asks a Different Question

New York does not use the ABC test as its general standard, so a practice operating on both sides of the river cannot assume the analysis travels.

For New York unemployment purposes the question is how much direction and control the practice exercises. The state looks at the whole picture. Who sets the schedule. Who assigns patients. Whether the practice's facilities and staff must be used. Who controls billing and fees. Who sets office procedures and supervises the work. New York draws a line between controlling the result and controlling how the work gets done, and some incidental control does not by itself create employment. But an office controlling scheduling, patient assignment, fees and billing is controlling a great deal more than the result.

These reviews almost always start the same way. An associate leaves, files for unemployment, and the inquiry that follows ends up covering everyone else in the office who was treated the same way.

11. If You Have Already Been Paying an Associate on a 1099

Most owners reading this are not deciding in the abstract. They have an arrangement in place and are now uneasy about it. A few federal programs exist, and they are worth knowing about before anything changes.

Section 530 relief. A business may be relieved of federal employment tax liability for workers treated as contractors if it had a reasonable basis for that treatment, treated all similar workers the same way, and filed all required 1099s. That last condition is unforgiving. Practices that never issued the 1099s generally cannot use it. It is also federal only and does nothing for New Jersey or New York.

Form SS-8. Either side can ask the IRS to determine a worker's status. It is slow, and determinations often come back as employee.

The Voluntary Classification Settlement Program. Eligible employers can reclassify workers going forward at reduced cost, subject to conditions around prior 1099 filings and not being under examination.

Timing matters with all three, and federal relief does not resolve the state side, which gets assessed separately. This is a conversation to have with your CPA and your employment counsel together, before anything changes on payroll.

12. This Is Not Only About Associates

Hygienists, temps, specialists rotating between offices and clinicians booked through staffing apps all run through the same tests. A short engagement does not make someone a contractor. An office that controls a temp hygienist's schedule, patients, operatory and protocols is exercising the same control it exercises over its own team. The hiring market driving a lot of this is covered in how to find a dental hygienist when no one is applying and how to structure staff pay and bonus plans.

It also comes up in transactions. Buyers look closely at how a seller classified associates and staff, because unpaid employment taxes can follow the practice depending on how the deal is structured. I see it during due diligence regularly, and it can affect what a buyer is willing to pay when the practice is valued. Across multiple locations the exposure multiplies, which is part of why structure matters so much in a DSO management services agreement and in scaling into a multi-office group.

When the associate is also your eventual buyer, classification runs straight into buy-in timing, which I wrote about in when your succession plan no longer fits your associate.

The Questions Worth Answering Before You Sign

Question	Why it matters
Who controls the days, hours, patients, fees and workflow?	Goes to control under every test
Does the dentist work mainly for one office?	Goes to independent business and economic dependence
Who provides the operatories, equipment, staff, billing and patients?	Goes to investment and financial control
Is the arrangement ongoing and central to the practice?	Goes to the nature of the relationship
Does the agreement match what actually happens?	The facts control, not the document
In New Jersey, can you satisfy all three prongs, including B?	One failed prong means employee treatment
In New York, how much direction and control is really exercised?	The central question in that state
Are clinicians doing the same work treated the same way?	Inconsistency is difficult to defend
Have 1099s been filed for every contractor, every year?	Required for Section 530 relief

Classification Is a Determination, Not a Preference

The practices that get into trouble here are almost never the ones that thought carefully and reached a defensible answer. They are the ones where nobody asked the question. An associate came on two days a week. Somebody suggested a 1099 would be simpler. The agreement got signed, the arrangement quietly became full time, and four years later the associate left and filed for unemployment.

The better sequence is not complicated. Determine the classification first, with counsel, based on how the two of you will actually work. Then design compensation that works for both sides, and run the after-tax numbers so the associate knows what the offer is really worth and you know what it really costs.

That matters today, and it matters at the exit. Employment tax exposure is one of the things a sophisticated buyer looks for, and it is a poor reason to lose value in a practice you spent a career building.

At MRL Advisory Group, we work with dental practice owners and associates across New Jersey and New York on the financial side of these arrangements through our advisory services: compensation modeling, fully loaded payroll cost, collection targets, overhead impact and retirement plan design. We keep the numbers accurate through accounting and bookkeeping, handle the planning through tax services, and address the associate-to-owner path through transition advisory. Because classification is a legal determination, we work alongside your employment counsel on that piece rather than in place of it. If you are hiring an associate, renegotiating an agreement, or uneasy about how a current 1099 arrangement would hold up, schedule a free consultation and let's look at the numbers together.

Please note: The rules described in this article are very likely to change. Worker classification standards shift with new legislation, new regulations, agency enforcement priorities and court decisions, and they have changed repeatedly at both the federal and state level in recent years. This article reflects the general landscape as of the review date at the top and is not updated automatically.

This article is provided for general educational purposes only. It is not legal advice, tax advice or accounting advice, and reading it does not create a client or attorney-client relationship of any kind. Nothing in it should be relied on in deciding how to classify a worker or how to structure, change or end any working arrangement.

Every situation is unique. Worker classification turns entirely on the specific facts of a specific relationship, and two arrangements that look similar on paper can produce different results under federal law, New Jersey law and New York law. Readers must obtain their own counsel. Anyone classifying a worker, signing an associate agreement, or considering a change to an existing arrangement should consult a qualified employment attorney and their own tax adviser about their particular circumstances before taking any action.
