Selling a dental practice is one of the most significant financial events in a dentist’s career. While maximizing the sale price is important, the way the transaction is structured can have an even greater impact on how much you keep after taxes.
Proper tax planning—done well before the sale—is essential to preserving your wealth and minimizing unnecessary tax exposure.
1. Understand the Current Tax Landscape
For higher-income dentists, the 3.8% Net Investment Income Tax (NIIT) often applies to gains from the sale of a practice, depending on how the transaction is structured. Additional state-level taxes can also increase the overall tax burden, making timing and structure crucial.
Because tax laws can shift with new legislation, it’s important to model multiple sale scenarios before finalizing a deal. A proactive approach allows you to plan for both current rules and potential changes.
2. Qualified Small Business Stock (Section 1202)
Under IRC Section 1202, owners of Qualified Small Business Stock (QSBS) may exclude a portion or all of the gain on a sale if strict requirements are met. Recent legislation has expanded these benefits for stock issued after July 4, 2025. The business must be organized as a C corporation, held for the required period (three years minimum for new stock), and meet certain asset thresholds.
However, professional service fields—including dental practices—are generally excluded from QSBS benefits. While most traditional dental practices won’t qualify, related ventures such as dental labs, dental equipment companies, or dental software businesses may be eligible if they meet all requirements and don’t primarily provide professional health services.
3. Use Installment Sales to Manage Tax Liability
An installment sale allows sellers to recognize gain over time as payments are received, rather than all in one year. This approach can spread income across multiple tax years, reduce exposure to higher tax brackets, and improve post-sale cash flow.
Not every sale qualifies for installment treatment. Sales of inventory cannot be reported on the installment method, and depreciation recapture must be recognized in the year of sale regardless of when payments are received. Proper documentation and compliance are essential.
4. Incomplete Gift Non-Grantor (ING) Trusts
For dentists in high-tax states, ING trusts (such as NING or DING trusts) may offer state tax planning opportunities. In general, an owner transfers practice ownership to a non-grantor trust in a state with no income tax. The trust then sells the practice, and depending on state law, proceeds may avoid state income tax.
This approach must be set up well before a buyer is identified and requires specialized legal and tax guidance. Several states including New York, California, and Connecticut have enacted legislation to close this planning opportunity. The effectiveness of an ING trust depends heavily on the specific laws of both the state where the trust is established and the state where the grantor resides.
5. Charitable Remainder Trusts (CRTs)
A Charitable Remainder Trust (CRT) can allow a dentist to defer capital gains tax on the sale of a practice, receive income for life or a set term, and support a charitable cause.
When appreciated practice assets are transferred to a CRT, the sale can occur inside the trust without immediate recognition of gain. The donor receives both an income stream and a charitable deduction, with the remainder ultimately benefiting charity. CRTs typically make sense only for larger practice sales where the tax benefits and charitable goals align with the owner’s long-term objectives.
6. Stock vs. Asset Sales
How a dental practice sale is structured—stock sale vs. asset sale—has major tax consequences. Stock sales usually result in long-term capital gains, often taxed at favorable rates. Asset sales can trigger ordinary income on certain components, such as equipment or goodwill, and may cause double taxation for C corporations if proceeds are distributed to shareholders.
S corporations may provide greater flexibility, but liquidation and basis adjustments must be managed carefully. Determining the optimal structure early can maximize after-tax proceeds and reduce audit risk.
7. Purchase Price Allocation
In an asset sale, the purchase price allocation among categories such as equipment, inventory, and goodwill determines how much of the gain is taxed as ordinary income vs. capital gains. Both buyer and seller must report consistent allocations on IRS Form 8594. Strategic allocation can materially affect the seller’s final tax bill, making it an important part of negotiation.
