As December winds down, dental practice owners have a limited window to implement strategies that can meaningfully reduce their 2025 tax liability. Recent tax law changes create both new opportunities and considerations that make year-end planning particularly important this year.
Here are the key strategies every practice owner should evaluate before the calendar turns.
Take Advantage of Enhanced Equipment Deductions
Year-end equipment purchases have always been a popular tax strategy for dentists, and recent changes make this approach even more attractive.
Bonus depreciation has been restored to 100% and made permanent for qualifying assets. This means if you purchase and place dental equipment in service before December 31, you can potentially deduct the full cost this year rather than depreciating it over time.
Section 179 expensing limits have also increased significantly to $2.5 million with a $4 million phase-out threshold. What makes Section 179 particularly valuable is its flexibility—you can apply it selectively to specific assets rather than entire categories.
Section 179 also covers improvements that bonus depreciation doesn’t, including building systems like HVAC, roofing, security systems, and fire protection. For practice owners who’ve been putting off facility improvements, this creates a compelling tax incentive.
Keep in mind that assets must be purchased and placed in service by year-end to qualify. Simply ordering equipment isn’t enough—it needs to be delivered, installed, and ready for use in your practice.
Review Your Pass-Through Entity Tax Election
Many dental practices structured as S-corporations or partnerships use state-level Pass-Through Entity Tax (PTET) elections to work around federal limitations on state and local tax deductions.
Recent federal changes have temporarily increased the SALT cap to $40,000, but this benefit phases out at higher income levels. This means PTET elections may still provide advantages, particularly if:
- Your income exceeds the phase-out thresholds
- You typically take the standard deduction
- Reducing your pass-through income helps you manage other tax obligations
However, PTET elections can also affect your Qualified Business Income deduction, so these decisions require coordinated planning. If your state offers PTET and you haven’t evaluated whether it makes sense for your situation, now is the time to analyze the numbers.
Optimize Your Qualified Business Income Deduction
Pass-through dental practices may qualify for a 20% deduction on qualified business income—a significant tax benefit that’s directly tied to how you manage your practice finances.
Because dental practices are classified as specified service businesses, your income level determines whether you qualify for the full deduction, a partial deduction, or no deduction at all. This makes income management particularly important.
Year-end strategies to maximize this deduction include:
- Increasing W-2 wages paid by your practice if you’re limited by the wage-based calculation
- Purchasing qualifying equipment before year-end
- Accelerating deductible expenses into 2025
- Evaluating whether to defer income into the following year
The interplay between income levels, wages, and equipment purchases creates planning opportunities that are unique to each practice’s situation.
Consider Research and Experimental Expense Treatment
Recent changes provide new options for deducting research and experimental expenses, which may apply to practices investing in:
- Digital workflow systems
- Custom software development
- Clinical process improvements
- Structured training programs
Domestic research expenses can now be amortized over five years rather than the longer periods previously required. Additionally, qualifying small businesses may be able to claim deductions retroactively for expenses incurred in prior years.
If your practice has made these types of investments, reviewing how they’ve been treated for tax purposes could reveal opportunities.
Time-Tested Strategies Still Apply
Beyond the newer provisions, traditional year-end tax strategies remain valuable:
- Maximizing retirement contributions (or establishing a plan if you haven’t already)
- Timing income and expense recognition based on your expected tax situation
- Reviewing estimated tax payments to avoid penalties
- Implementing charitable giving strategies
- Ensuring S-corporation owner compensation is properly documented
