Kimberly Green | 2025-05-11

Dental overhead averages 62% of collections (ADA 2024). A niche CPA can cut taxes and free cash for hygiene staff. Five biggest levers: Section 179 timing, practice buy-in structure, S-corp wages, retirement layering, and AR management. Ready to upgrade?

Associate-to-partner buy-ins create goodwill vs. asset-allocation puzzles. Hygienist wage inflation squeezes margins. Five Services a Dental CPA Delivers 1. Section 179 & Bonus Depreciation on Equipment 80% bonus depreciation drops to 60% in 2025 (IRC 168(k)); timing a CBCT or chair package write-off matters. Example: A Dentist wrote off $240K in Year 1, freeing $75K to hire a second hygienist and boost production. 2. Practice Buy-In Structuring Seller-financed notes allocate price to goodwill (15-yr amortization) vs. hard assets (bonus depreciation). Example: Splitting $900K sale price 60% goodwill / 40% equipment saved the buyer $31K in first-year taxes. 3. Reasonable S-Corp Wages IRS looks at ADA total-comp studies; dropping owner W-2 from $300K to $210K saved $18K payroll tax while staying within safe harbor. Example: Section 199A deduction preserved an extra $22K. 4. Retirement Plan Layering 401(k) Safe Harbor plus cash-balance lets an owner-operator over 50 shelter up to $285K (IRS Notice 2020-62 tables). Example: Cash-balance credit formula mirrors hygienist payroll to avoid nondiscrimination testing. 5. AR Management & 13-Week Cash-Flow Forecast Dentrix/Open Dental exports feed collections forecasts and insurance-aging dashboards. Example: CPA-automated weekly follow-ups cut 60-day receivables by $110K in six months for a pediatric practice. Frequently Asked Questions What does a dental CPA cost? $5K–$12K per year plus bookkeeping if needed. Multi-location groups may pay $25K+ retainer for CFO-level forecasting . Can I deduct new operatories immediately? Yes—179 or bonus depreciation; cost segregation accelerates build-out. IRS Form 4562 attaches the election; a cost-seg report supports bonus claims. Is goodwill on a practice purchase deductible? Yes—15-year straight-line amortization (IRC197). Accelerating asset portion via bonus lowers first-year tax but raises basis. Should dentists use cash or accrual accounting? Cash until gross receipts exceed $25M; accrual gives truer profit. Many stay cash under $10M to defer insurance receivable income. Red Flags • “Dental?
