Dental Practice Asset Sale vs. Stock Sale: Taxes (2026)

Selling the assets instead of the practice costs a dentist about $33,000 more on a $1.5 million sale. Buyers ask for it anyway, and usually get it.

Three things decide how much of that gap you actually pay:

• What lands on your equipment. Chairs and scanners you already wrote off get taxed like wages, not like a sale.
• Who owns your reputation. Some of what they are buying may be yours personally, not the practice’s. That part is taxed once.
• Your entity. A C corporation changes the answer completely, and most dentists do not know which one they have.

The Two Ways to Sell

You can sell the things, or you can sell the company that owns them.

• An asset sale. The buyer takes your chairs, your patient list and your name. Your corporation stays with you, and so does its history. Every item gets its own price, on IRS Form 8594.
• A stock sale. The buyer takes the whole company. One price, one line, and your old problems go with it.

Why Buyers Want the Assets

Two reasons, and both are worth real money to them.

• They get to write it off. Goodwill bought in a practice sale is deducted over 15 years. Buy your stock instead and they deduct nothing.
• They leave your history behind. A malpractice claim from 2019, an unpaid payroll tax, a lease dispute. In an asset sale those stay yours.

Their lawyers say the same thing. Buyers prefer an asset sale because they can take depreciation and amortization deductions that lower their taxable income.

Why It Costs You More

Because your equipment gets taxed twice as hard as everything else.

• Dental is equipment heavy. Chairs, the scanner, the CBCT, the mill.
• Most of it is already deducted. You took the write-off in the year you bought it.
• So the buyer’s price on it is taxed like income. Not at the lower rate a sale usually gets. IRS Publication 544 sets out how.

The rest of the price, mostly your name and your patient list, is taxed at the lower rate either way. On top of both sits the 3.8% investment income tax.

The Math on a $1.5 Million Practice

Take a $1.5M sale. You put in $150,000 originally, you run an S corporation, and you are in the 20% bracket.

If they buy the company

• Your gain is $1.35M, all at the lower rate.
• Federal tax: $270,000.
• Investment income tax: $51,000.
• Total: about $321,000.

If they buy the assets

• Say $250,000 lands on equipment you already wrote off.
• That piece is taxed like wages: $92,500.
• The other $1.25M, less what you put in: $220,000.
• Investment income tax: $42,000.
• Total: about $354,000, or $33,000 more.

Move $100,000 of that allocation off the equipment and onto the patient list and you keep roughly $17,000 of it. That single line is worth more than most of what you will argue about.

The Goodwill Argument Only Dentists Can Make

Some of what a buyer is paying for is not the practice. It is you.

• The specialists who send you cases.
• The families who have seen you for twenty years.
• The reputation attached to your name, not the sign.

Tax law calls that personal goodwill. In the right structure you sell it directly, rather than through your corporation.

Two things have to be true. It has to genuinely be yours, not something you already signed over. And you cannot have an employment agreement or non-compete with your own practice that hands it to the company.

Check that second one before you do anything else. Many dentists signed exactly such an agreement when they incorporated, and it quietly gives the argument away.

If You Are a C Corporation, Read This Twice

An asset sale inside a C corporation is taxed at the company, and taxed again when the money reaches you.

This is where personal goodwill stops being a nice extra and starts being the whole game. Anything you sell personally never enters the corporation, so it is taxed once rather than twice.

• Ask your accountant now. S corporation, C corporation, or something else.
• Do it before you take an offer. Not after the letter of intent is signed.
• Assuming costs real money. Dentists who assume S and turn out to be C lose more on that one fact than on any other line.

Your Credentials Do Not Come With the Practice

This surprises people, so it is worth stating plainly. Structure changes almost nothing here.

• Your DEA registration is yours. The buyer applies for their own.
• So is your state controlled substances permit. Same answer either way.
• Credentialing follows the provider, not the building. Re-credentialing a buyer runs 60 to 120 days, and the standard most plans are accredited against caps the verification at 120.

Start that clock at the offer, not at closing. It is the one part of a dental sale that no amount of structuring makes faster.

Where You Practice Changes the Total

State tax sits on top of all of this, and the two states differ sharply.

• Pennsylvania: a flat 3.07% on the gain.
• New Jersey: no separate rate for a sale. It is ordinary income, at rates reaching 10.75%.

On a $1.5M practice that difference is larger than the asset-versus-stock gap itself.

Settle This Before You Sign

The allocation is decided in the letter of intent, not at closing. By the time a purchase agreement is drafted, the numbers are usually treated as settled.

1. Ask your accountant which entity you have, today.
2. Pull your equipment schedule and see how much you have already deducted.
3. Read your own employment agreement with your practice, if one exists.
4. Put a personal goodwill number in the letter of intent, not after it.
