The recently introduced One Big Beautiful Bill Act (OBBBA) is packed with tax law changes that could significantly impact small businesses, investors, and practice owners. While it’s a dense piece of legislation, several provisions stand out as especially relevant for dentists and healthcare entrepreneurs who are balancing growth, tax planning, and long-term financial strategies.
Below are 10 highlights worth understanding, along with insights on how they may affect dental practices and other closely held businesses.
1. Expanded Qualified Small Business Stock (QSBS) Rules
For owners considering a future practice sale or partnership exit, the updated Section 1202 rules are important. The OBBBA increases the per-taxpayer exclusion for gains on qualified small business stock from $10 million to $15 million (per issuer), with inflation adjustments beginning in 2027.
The law also introduces a tiered exclusion system:
- 50% gain exclusion after three years,
- 75% after four years, and
- 100% after five years.
This flexibility allows practice owners and investors to plan exits more strategically while avoiding alternative minimum tax complications.
2. Full Expensing for U.S.-Based Research and Development
Dental practices investing in new technology, clinical research, or process improvements could benefit from permanent 100% expensing of U.S.-based research and experimentation costs. Previously, these expenses had to be spread over several years. Now, they may be deducted immediately, providing a valuable cash flow advantage.
Smaller practices with less than $31 million in annual receipts may also have opportunities to apply these changes retroactively through amended filings, which could result in refunds.
3. Adjustments to International Tax Rules
While most dental practices won’t be directly affected by international tax provisions, larger dental groups with overseas investments or suppliers should be aware of reduced deductions for foreign-derived intangible income and slight increases in anti-abuse tax rates. These changes emphasize a continued push toward domestic investment.
4. Business Interest Deduction Relief
Debt financing is common in dentistry, particularly for startups, acquisitions, or expansions. The OBBBA modifies Section 163(j) to once again include depreciation and amortization in adjusted taxable income when calculating deductible business interest. This means practices carrying debt may be able to deduct more of their interest expense, improving after-tax profitability.
5. Permanent Paid Family Leave Credit & Enhanced Meal Deductions
To help with recruitment and retention, the legislation makes the paid family and medical leave credit permanent. This gives practice owners a stable incentive to provide meaningful employee benefits.
In addition, the Act temporarily restores the 100% deduction for certain business meals purchased from restaurants between 2025 and 2027. While this isn’t a core tax saver for most dentists, it’s a helpful benefit for team-building or professional development meetings.
6. Higher SALT Deduction Caps & PTET Workarounds
State and local tax (SALT) deduction limits have been a point of frustration for many high-earning professionals. Beginning in 2026, the OBBBA raises the SALT cap to $40,000 ($20,000 if married filing separately) with annual inflation adjustments. However, this relief is temporary and phases out after 2030.
Pass-through entity tax (PTET) elections remain an important workaround for dentists operating as S corporations or partnerships in high-tax states.
7. Section 199A Deduction Becomes Permanent
The 20% qualified business income (QBI) deduction, a major tax savings tool for practice owners structured as S corporations, partnerships, or sole proprietorships, is now permanent. This certainty makes entity structure decisions clearer and continues to provide long-term benefits to dental business owners.
8. Long-Term Community Investment Incentives
The OBBBA solidifies programs like the Low-Income Housing Tax Credit, New Markets Tax Credit, and Opportunity Zones. While these provisions aren’t directly tied to dental practices, investors and dental entrepreneurs who diversify into real estate or community development projects may see new opportunities.
9. Bonus Depreciation and New Deduction for Production Property
The Act permanently extends 100% bonus depreciation for qualifying property with a recovery period of 20 years or less, such as dental equipment, technology, and office improvements.
Additionally, a new deduction (Section 168(n)) applies to businesses that produce or construct property for their own use. For dental practices building out custom facilities, this provision could accelerate deductions and reduce taxable income in the year of investment.
10. Temporary Deductions for Tips and Overtime
Although not directly aimed at dental practices, the Act introduces deductions for tip income and overtime pay. For practices with hourly staff or employees working extended schedules, these changes may provide modest benefits at the individual level.
Why This Matters for Dental Practice Owners
The OBBBA reshapes several key areas of tax planning, from entity structure decisions to equipment purchases, employee benefits, and long-term exit strategies. For dentists, it highlights the importance of strategic tax planning before making major financial moves such as expanding, selling, or investing in new technology.
While the Act offers valuable opportunities, the details are nuanced. Some provisions apply immediately, others retroactively, and many are temporary. Aligning your practice’s financial strategy with these changes can unlock significant savings and help you position for long-term growth.
