Before You Hand an Associate the Keys: Tax & Structure Questions First

The agreement looks clean, the associate is talented, and everyone is excited to move forward. That is exactly when practices make the most expensive structural mistakes, because the legal documents get signed before anyone has run the tax math.

This piece is not about which choice is right for your practice. It is about the questions you must answer, and the sequence in which to answer them, before a single line of an agreement gets drafted.

The Classification Question Is Not Optional

Every dental practice that brings on an associate has to take a position on one threshold question: is this person an employee or an independent contractor? Many owners treat this as a preference. The IRS and most state agencies treat it as a legal determination, and they have enforcement tools to back that up.

The classification hinges on the degree of behavioral control, financial control, and the nature of the relationship. In a dental context, the more the practice controls when the associate works, which patients they see, what equipment they use, and how they perform procedures, the stronger the argument for employee status. A true independent contractor relationship typically involves the contractor operating with meaningful autonomy, carrying their own malpractice insurance, potentially working for multiple practices, and bearing real economic risk.

The practical problem is that many dental associate arrangements look and feel like employment, but get papered as independent contractor relationships to reduce payroll costs and administrative complexity. That gap creates real exposure:

• Misclassified workers can trigger payroll tax liability for the practice, sometimes retroactively over multiple years
• State agencies often apply their own, sometimes stricter, tests independently of the federal standard
• The associate themselves may later file for unemployment or workers' compensation, which initiates a review
• Employee benefits that were never provided, including retirement plan contributions, may become a point of negotiation or dispute

None of this means independent contractor arrangements are wrong for dental associates. Some are entirely defensible. But the structure has to actually match the facts on the ground, and those facts need to be reviewed by a CPA and employment attorney before the relationship starts, not after a complaint is filed.

The Associate Entity Question Is Separate, and It Matters

Assume for a moment that the associate qualifies as an independent contractor. A related question immediately follows: should the associate form their own entity, and does the practice have a preference?

Some practices require associates to contract through a professional corporation or LLC rather than as individuals. This is common in states that permit or require it, and it can have implications for both parties. For the associate, operating through an entity may create opportunities for retirement plan contributions, health insurance deductions, and S-corporation salary planning that a W-2 relationship forecloses. For the practice, it may shift certain compliance obligations.

For the hiring practice owner, the key point is that the structure of the associate relationship affects your own entity's tax position, too. If your practice is an S-corporation, the compensation structure you build for an associate (whether payroll, a production split, or a guaranteed draw) has to work within the framework of your existing entity without creating unintended tax consequences.

This is a conversation for your CPA before the term sheet goes out.

Buy-In Structure Determines Tax Outcome for Both Sides

When an associate moves toward ownership, the tax conversation becomes substantially more consequential. How the buy-in is structured determines how each party is taxed on the transaction, and the interests of buyer and seller are not automatically aligned.

Consider an anonymized composite. A solo owner, practicing for fifteen years, agrees to sell a fifty-percent interest to a longtime associate. They shake hands on a number. Then they each hire their own attorneys, who draft documents, and they sign. Eighteen months later, during a routine review, a CPA points out that the allocation of purchase price between assets and goodwill was never formally agreed upon and documented. The result is a dispute about how the transaction gets reported, and both parties end up with worse tax outcomes than either would have accepted had the question been answered in advance.

The core tension in any dental practice buy-in involves what is actually being sold. Dental practice value is often concentrated in goodwill, which can be personal goodwill (attached to the selling dentist's relationships and reputation) or practice goodwill (attached to the business itself). How that goodwill is characterized, and how the purchase price is allocated across tangible assets, equipment, non-competes, and goodwill categories, affects whether the seller recognizes ordinary income or capital gains, and whether the buyer gets a basis they can depreciate or amortize.

For the buyer, amortizable intangibles and deductible purchase components are more valuable than a lump allocation to goodwill that produces slow recovery. For the seller, capital gains treatment is typically preferred over ordinary income. These interests can conflict, and resolving them requires a CPA who understands both positions before the purchase price allocation is locked in.

Additional structure questions that affect tax treatment:

• Installment sale versus lump sum. An installment arrangement spreads the seller's gain recognition over time, which can be valuable depending on the seller's other income in the year of sale. It also extends the buyer's cash commitment.
• Entity type at the time of sale. An S-corporation sale can be structured as a stock sale or an asset sale, and the tax treatment differs significantly. A dental practice operating as a sole proprietorship has no stock to sell.
• Earnouts and contingent consideration. Production-based earnout structures are common in dental transitions but introduce complexity around when and how the seller recognizes income.
• Non-compete agreements. Amounts allocated to a non-compete are ordinary income to the seller and amortizable over fifteen years for the buyer under current law. The allocation matters.

The CPA Conversation Belongs at the Beginning

The single most consistent pattern in practice transitions that go sideways is sequence. The owners negotiate, the attorneys draft, the documents get signed, and then the CPA is handed the paperwork and asked to make it work. At that point, the options narrow considerably.

Involving a CPA before the letter of intent is far more valuable than involving one after the purchase agreement is signed. The pre-agreement stage is where entity structure can still be adjusted, where purchase price allocation can be negotiated on terms that serve both parties, where payroll setup can be designed correctly from day one, and where retirement plan implications can be modeled before commitments are made.

A few questions worth bringing to that early conversation:

• Does our current entity structure accommodate a new owner, or does it need to be restructured first?
• What is the most tax-efficient way to structure the buy-in given each party's current income situation?
• If we are doing an installment sale, what are the interest and income recognition implications?
• How does the associate's compensation structure during the transition period affect both parties' tax positions?
• What retirement plan opportunities exist, and does the new structure change them?

Bringing an associate into ownership is one of the most significant financial events in a practice owner's career. The tax outcomes are not fixed by the market or the economy. They are determined by the structure, and the structure is determined by decisions made before the documents are signed.

FAQ

Can I pay an associate as an independent contractor and also control their schedule? Generally, no. Control over schedule is one of the behavioral control factors that points toward employee classification. The facts of the arrangement determine the classification, not the label on the contract.

Does the associate need their own CPA for a buy-in? Yes. The buyer and seller have different tax interests, and each party benefits from independent advice. A single advisor cannot fully represent both sides.

When is the best time to restructure the practice entity before a buy-in? Typically well before the transaction closes. Some restructuring steps have holding period or tax implications that make last-minute changes costly or ineffective.

What is personal goodwill, and why does it matter? Personal goodwill is value attributed to the individual dentist's relationships, skills, and reputation rather than to the practice as a business. Its characterization in a sale can affect how the proceeds are taxed for the seller and how the buyer recovers costs.
