As the year winds down, dental practice owners face a familiar challenge: balancing patient care, staff goals, and the pressing question of how to minimize their tax bill.
This year, the opportunity is particularly significant. With new provisions under the One Big Beautiful Bill Act now in effect and Tax Cuts and Jobs Act elements made permanent, dentists have a genuine opportunity to strengthen both their immediate tax position and long-term financial planning.
Think Beyond Year-End Tactics
Many practice owners equate tax planning with pushing income forward or prepaying expenses in December. True tax planning goes much deeper.
The most effective approach examines your entire financial picture—business income, payroll structure, retirement contributions, and investment strategy—to create a cohesive plan that builds wealth throughout the year. Year-end planning is important, but it’s most powerful when built on a foundation of intentional, ongoing strategy.
Review Entity-Level Tax Opportunities
If your practice operates as an S-Corporation or Partnership, explore whether your state allows a Pass-Through Entity (PTE) tax election. This strategy enables you to pay certain state income taxes at the business level, converting what would normally be a nondeductible personal expense into a deductible business deduction.
Because most PTE deadlines fall on December 31, this is an urgent conversation to have with your CPA before year-end. The potential savings can be substantial, depending on your income level and state regulations.
Optimize Owner Compensation and QBI Planning
The Qualified Business Income (QBI) deduction—now permanent under recent legislation—allows eligible business owners to deduct up to 20% of qualified business income. However, the way you compensate yourself directly impacts this deduction.
The balance between W-2 wages and K-1 distributions affects both your QBI deduction eligibility and your payroll tax exposure. Year-end is the ideal time to review this ratio with your CPA and adjust before your final payroll runs for the year.
Maximize Retirement Contributions
The final quarter often brings strong cash flow—making it an excellent time to evaluate your retirement savings strategy. For 2025, 401(k) limits are $23,500, or $31,000 if you’re age 50 or older.
If you’ve already maximized standard plans and have additional funds to invest, consider a cash balance or defined benefit plan to defer more income while accelerating long-term retirement savings. The Secure Act 2.0 continues to offer tax credits for practices establishing new retirement plans, so this may be the right moment to explore that option.
Make Intentional Equipment and Expense Decisions
December often triggers impulse equipment purchases for tax write-offs. Before making that investment, pause and consider the bigger picture.
Tax deductions are only worthwhile when they also improve profitability or operational efficiency. If an equipment purchase will genuinely increase production capacity or practice efficiency, buying before year-end makes sense—especially since favorable depreciation rules remain in place. Remember that equipment must be placed in service (installed and ready for use) by December 31 to qualify for a 2025 deduction.
Evaluate Expense Timing
If you’re planning supplies, continuing education, or business travel for early 2026, paying for these before December 31 reduces your current-year taxable income. However, if your income is projected to increase significantly next year, deferring some deductions might provide greater overall benefit.
A year-end tax projection can clarify which timing strategy serves you best.
Don’t Overlook Personal Tax Moves
A few often-missed opportunities include backdoor Roth contributions (complete both steps before year-end), charitable giving strategies, and confirming adequate tax payments to avoid penalties. If you use your home for legitimate business purposes like client meetings or professional retreats, document this carefully—the tax benefits can be meaningful when properly recorded.
Plan for the Road Ahead
Some of today’s strong tax benefits are scheduled to change or phase out after 2026. Your year-end review should include a forward-looking assessment to help your practice adapt as the rules evolve.
The Bottom Line
Year-end tax planning for dentists isn’t just about reducing this year’s bill, it’s about building a financial system that supports sustainable growth and long-term security. By taking time now to evaluate your entity structure, compensation strategy, retirement planning, and expense timing, you’ll enter 2026 with clarity and confidence.
