Legal, Tax, and Lease Issues When Selling a Dental Practice

Most dentists sell a practice only once. Buyers, lenders, attorneys, brokers, DSOs, and transition advisors may go through the process repeatedly.

That experience gap matters.

A dentist may look at a sale and think, “The buyer agreed to the price, so the hard part is done.” In reality, the purchase price is only one part of the transaction. The sale still has to move through legal review, due diligence, tax planning, lease assignment, financing, document negotiation, and closing.

Problems often appear when these issues are handled too late.

A buyer may be ready to close, but the landlord has not approved the lease assignment. A seller may accept an offer, then realize the after-tax proceeds are lower than expected. A purchase agreement may include restrictive covenants or post-sale obligations that were not discussed clearly during negotiations. Accounts receivable may be treated differently than the seller assumed.

None of these issues are unusual. But they are easier to manage before the sale is under pressure.

A good sale is not just the highest offer. It is a deal you can close, understand, and keep more of after taxes, lease issues, and legal obligations are handled correctly.

The dental practice purchase agreement is one of the most important documents in the sale.

This agreement defines what is being sold, how the buyer will pay, what happens before closing, what obligations continue afterward, and what protections each side has if something goes wrong.

It may address purchase price, payment terms, assets included in the sale, excluded assets, liabilities, accounts receivable, patient records, employee matters, closing conditions, representations and warranties, non-compete terms, confidentiality, transition responsibilities, and dispute resolution.

Do not treat this document as a formality.

By the time a purchase agreement is drafted, you may feel emotionally committed to the deal. You may already be imagining retirement, a transition period, or life after ownership. That is exactly why the agreement needs careful review.

A dental practice sale can include details that a general business attorney may not see every day. Patient records, goodwill, restrictive covenants, treatment obligations, accounts receivable, equipment leases, insurance participation, and staff transition issues can all matter.

Work with a dental practice attorney or attorney experienced in dental transactions before signing. The goal is not to create friction. The goal is to make sure the agreement reflects the business deal you believe you accepted.

One early legal question is what is actually being sold.

Many dental practice transactions are structured as asset sales. In an asset sale, the buyer purchases specific assets of the practice rather than buying the legal entity itself.

Those assets may include equipment, furniture, supplies, patient records, goodwill, phone numbers, websites, trade names, and certain assignable contracts.

In some cases, a transaction may be structured as a stock sale or equity sale. That means the buyer purchases ownership of the legal entity that owns the practice.

Each structure has different legal and tax implications. Buyers and sellers may prefer different structures for different reasons. Liability, contracts, taxes, entity type, financing, and deal complexity can all affect the decision.

Do not assume the structure is a minor technicality. It can affect taxes, risk, and what obligations transfer to the buyer.

Your attorney and dental CPA should review the proposed structure before you agree to final terms.

The purchase agreement should be reviewed as a whole, not just for the purchase price.

Pay attention to how the agreement handles assets, liabilities, accounts receivable, patient records, transition duties, employee matters, warranties, restrictive covenants, and closing conditions.

For example, accounts receivable can be handled several ways. The seller may keep AR, the buyer may purchase it, or the parties may agree to a collection arrangement. If this is not clear, it can create disputes after closing.

Patient records also require careful handling. The buyer needs access to continue care, but records must be transferred or made available in a way that complies with legal and ethical requirements.

Restrictive covenants matter as well. A non-compete, non-solicitation, or non-disparagement provision can affect what you can do after closing. If you plan to continue practicing, teach, consult, relocate, or remain active in dentistry, these terms need to be understood before signing.

Representations and warranties are another area sellers often overlook. These are statements you make about the practice, its records, its obligations, and its operations. If they are inaccurate, they can create post-closing exposure.

This is why legal review matters before you sign, not after.

Taxes can significantly affect what you keep from the sale.

The sale price and your net proceeds are not the same. Your actual outcome may depend on deal structure, purchase price allocation, entity type, state and federal tax rules, debt payoff, transaction costs, installment payments, earnouts, and whether any equity is involved.

This is why dental practice sale taxes should be discussed before the deal is finalized.

If you wait until closing to ask tax questions, your options may be limited. By then, the purchase agreement may already define the structure, allocation, and timing of payments.

A dental CPA can help estimate your after-tax proceeds and compare how different structures may affect your outcome. That does not mean every tax issue can be avoided. It means you should know what to expect before signing.

This is especially important if your deal includes seller financing, an earnout, rollover equity, real estate, or a post-sale employment arrangement. Each can affect timing, taxation, risk, and planning.

The question is not just, “What is the buyer offering?”

The better question is, “What will I actually keep, when will I receive it, and what obligations remain after closing?”

Purchase price allocation is one of the most important tax issues in a dental practice sale.

In many transactions, the purchase price is divided among different asset categories. These may include equipment, furniture and fixtures, supplies, goodwill, patient records, restrictive covenants, and other intangible assets.

Those allocations can affect taxes for both buyer and seller.

The buyer and seller may not have the same preferred allocation. One allocation may be more favorable to the buyer’s depreciation or amortization goals. Another may be more favorable to the seller’s tax outcome.

Because the allocation can affect what you keep after taxes, it should not be treated as a last-minute detail. Your dental CPA should review the proposed allocation before the agreement is finalized.

This is also a reason to avoid evaluating offers by purchase price alone. Two offers with the same headline price can produce different after-tax outcomes depending on how the transaction is structured and allocated.

If you lease your office, the lease may be one of the most important documents in the entire sale.

A profitable practice can still run into trouble if the buyer cannot continue operating from the same location. Buyers and lenders usually want confidence that the practice location is secure after closing.

This is where dental practice lease assignment becomes important.

A lease assignment is the process of transferring the seller’s lease rights and obligations to the buyer, usually with landlord approval. Some leases allow assignment with consent. Others contain restrictions, notice requirements, personal guarantee provisions, or terms that can complicate the transaction.

Before going to market, review the lease for remaining term, renewal options, assignment language, landlord consent requirements, rent increases, exclusivity provisions, relocation clauses, and personal guarantees.

If the lease expires soon, the buyer may worry about location security. If the lease cannot be assigned without landlord consent, the closing may depend on landlord cooperation. If the seller remains personally liable after assignment, that needs to be understood and negotiated.

Lease issues are especially frustrating because they can delay a sale even when the buyer and seller agree on price.

Do not wait until the final weeks before closing to discover that the lease creates a problem. Review it early with your attorney or lease advisor.

If you own the building, the transaction has an additional layer.

You need to decide whether to sell the real estate with the practice, lease the space to the buyer, or keep the real estate as a separate investment.

Each path has different financial, tax, and lifestyle implications.

Selling the building may create liquidity and simplify your exit, but it may also trigger tax consequences and remove future rental income. Leasing the building to the buyer may create ongoing cash flow, but it also means you remain a landlord after selling the practice. Keeping the real estate can be attractive, but only if the lease terms, tenant quality, and long-term plan make sense.

The real estate decision should be modeled with your CPA, attorney, financial planner, and real estate advisor when relevant. It should not be treated as an afterthought.

Selling a dental practice involves legal, tax, financial, operational, and transition decisions. No single advisor covers all of them.

A strong advisory team may include a dental attorney, dental CPA, transition advisor or dental practice broker, financial planner, and lease or real estate advisor.

A dental practice attorney helps review and negotiate legal documents, including the letter of intent, purchase agreement, employment agreement, lease assignment, restrictive covenants, and post-sale obligations.

A dental practice CPA helps estimate after-tax proceeds, review purchase price allocation, evaluate deal structure, identify add-backs, and plan around tax consequences.

A transition advisor or broker may help with valuation, buyer screening, confidentiality, negotiations, and deal coordination.

A financial planner helps connect the sale to your retirement plan, investment strategy, debt payoff, estate planning, and post-sale income needs.

A lease advisor or real estate professional may be useful if the lease, building, or landlord negotiation is material to the transaction.

The key is not just having advisors. It is having advisors who understand dental practice sales and communicate with each other.

Your CPA’s tax guidance may affect legal terms. Your attorney’s contract changes may affect deal structure. Your broker’s negotiation strategy may need input from both. If your advisors work in silos, important issues can fall through the cracks.

Many dental practice sales close without major legal problems. But certain issues regularly create delays.

Lease assignment problems are among the most common. If landlord consent, renewal terms, or personal guarantees are not addressed early, closing can stall.

Missing corporate records can also create problems. Buyers and attorneys may need entity documents, ownership records, licenses, permits, tax identification information, or authority documents to confirm who can sell the practice.

Unclear contracts can slow the process as well. Equipment leases, vendor contracts, software agreements, associate agreements, independent contractor agreements, and service contracts may need to be reviewed before closing.

Accounts receivable disputes can also create friction. If the parties do not agree on who owns AR, who collects it, how credits are handled, or how old balances are treated, the issue can become contentious.

Other delays may come from unresolved legal claims, expired permits, missing employment records, unclear equipment ownership, or incomplete due diligence materials.

Most of these issues are manageable. The problem is timing. If they surface late, they become closing problems. If they are identified early, they can usually be addressed before they threaten the transaction.

The first common mistake is waiting too long to involve advisors.

Many dentists wait until after accepting an offer to call an attorney or CPA. By then, important business terms may already be set. It is much easier to shape a deal before documents are signed than to fix unfavorable terms afterward.

Another mistake is using general advisors without dental transaction experience. A general attorney or CPA may be competent, but dental practice sales include issues that are specific to the profession. Patient records, goodwill, restrictive covenants, insurance participation, AR, treatment continuity, and practice transition terms all require context.

Ignoring the lease is another major mistake. The practice location is often central to value. If the buyer cannot secure lease assignment or enough remaining term, financing and closing may become more difficult.

Sellers also overfocus on the gross purchase price. A larger offer does not automatically mean a better outcome if taxes, debt payoff, seller financing, earnouts, equity, or legal obligations reduce certainty.

Finally, some dentists sign documents they do not fully understand because they feel pressure to keep the deal moving. That is risky. If a provision affects your money, your ability to practice, your liability, or your post-sale obligations, slow down and get advice before signing.

Legal, tax, and lease issues can affect whether your sale closes, how much you keep, and what obligations remain after closing.

The earlier you review these issues, the more control you usually have. Before buyers, attorneys, CPAs, and lenders start asking for documents, organize your records, review your lease, understand your likely tax outcome, and make sure your advisor team is in place.
