Why Dental Practice Owners Overpay Taxes
Dentists earning $300K-$700K from practice ownership face a unique combination of high self-employment income, substantial equipment depreciation opportunities, and practice real estate that most generalist accountants fail to optimize. The average dental practice owner overpays by $54,000 to $81,000 annually due to suboptimal entity structure, missed depreciation elections, and underutilized retirement plan capacity.
Dental practices are capital-intensive businesses. CBCT scanners ($100,000-$250,000), CAD/CAM systems ($150,000+), digital impression units, and practice buildouts create substantial Section 179 and bonus depreciation opportunities under IRC Section 168(k). A single equipment purchase year can generate $200,000+ in accelerated deductions worth $74,000+ at the 37% marginal rate.
S-Corporation Optimization for Dental Practices
A dental practice generating $450,000 in net income should operate as an S-Corporation with reasonable compensation benchmarked against ADA Health Policy Institute surveys. General dentists document reasonable compensation of $180,000-$220,000; specialists (oral surgeons, periodontists, endodontists) support $280,000-$400,000. The spread between net income and reasonable salary flows as distributions exempt from the 15.3% self-employment tax, saving $15,750+ annually.
For multi-location dental practices or DSO-affiliated dentists, the entity structure becomes more complex. Separating clinical income (personal services corporation or S-Corp) from real estate holdings (LLC) and management entities creates multiple layers of tax optimization under IRC Sections 199A, 1231, and 469.
Equipment and Technology Depreciation Strategy
Dental practices should time major equipment purchases strategically. Under IRC Section 179, a dental practice can expense up to $1,220,000 of qualifying equipment in the year placed in service. Combined with 60% bonus depreciation under Section 168(k) (2025 rate), a $500,000 operatory buildout generates first-year deductions of $500,000, worth $185,000 in immediate tax savings.
Strategic timing means clustering purchases in high-income years, accelerating planned acquisitions into years with extraordinary income (partnership buyouts, associate buy-ins, insurance payouts), and deferring purchases from low-income years. A 5-year equipment replacement plan coordinated with tax projections can save $30,000-$60,000 in present-value taxes through timing alone.
Practice Real Estate Tax Planning
Over 60% of dental practice owners also own their practice real estate. This creates opportunities for cost segregation studies (reclassifying 20-40% of building cost to 5-7-15 year property), Section 1031 exchanges when upgrading facilities, and below-market lease arrangements between related entities. A dental office building worth $800,000-$1,500,000 typically generates $60,000-$150,000 in accelerated first-year deductions through cost segregation.

How much can dentists save with entity restructuring?
Dentists earning $300K-$700K typically save $36,000 to $81,000 annually through S-Corporation optimization, Section 199A planning, and multi-entity structuring. Savings compound over a career to $2M-$5M+.
What entity structure is best for dentists?
Most dentists benefit from S-Corporation election for active practice or business income, with separate LLCs for investment activities. The optimal structure depends on income level, state taxation, number of employees, and whether the Section 199A QBI deduction applies.
When should dentists implement tax planning?
The ideal time is January of the current tax year, allowing 12 months of strategic implementation. However, mid-year planning still captures 50-75% of annual savings. Entity elections (Form 2553) can be filed retroactively within 75 days of the tax year or with reasonable cause relief.
