Dental Equipment Tax Depreciation

Dental practices are equipment-intensive businesses. Between operatory chairs, digital X-ray systems, CBCT scanners, CAD/CAM machines, and sterilization equipment, a typical practice has hundreds of thousands of dollars in depreciable assets. The question is how — and how fast — you depreciate them.

Section 179 for Dental Equipment

Section 179 allows you to deduct the full purchase price of qualifying equipment in the year you buy it, rather than depreciating it over 5 to 7 years. For dental practices, qualifying equipment includes:

• Operatory equipment: Dental chairs, delivery systems, curing lights, handpieces
• Imaging systems: Digital X-ray sensors, panoramic units, CBCT scanners, intraoral cameras
• CAD/CAM systems: CEREC machines, 3D printers, milling units
• Sterilization equipment: Autoclaves, ultrasonic cleaners, instrument management systems
• Practice technology: Computers, servers, practice management software, patient communication systems
• Office furniture: Reception furniture, operatory cabinetry, lab workstations

Section 179 vs. Bonus Depreciation

Both provisions allow first-year expensing, but they work differently:

• Section 179 has an annual deduction limit (currently $1,220,000) and can't create a tax loss — it's limited to your business income
• Bonus depreciation has no dollar limit and can create a net operating loss that carries forward
• For most dental practices, Section 179 is sufficient. Bonus depreciation becomes valuable when making very large equipment purchases or when you want to create a loss for strategic tax planning

Timing Your Equipment Purchases

Strategic timing of equipment purchases is one of the most effective tax planning tools for dentists:

1. Year-end acceleration: Buying equipment before December 31 lets you take the full deduction in the current year
2. High-income years: When you have a year with unusually high income, equipment purchases can offset the spike
3. Pre-sale planning: If you're planning to sell your practice, accelerating equipment purchases beforehand can reduce your tax burden in the years leading up to the sale

Don't Forget the Office Build-Out

Beyond movable equipment, your office build-out may qualify for accelerated depreciation through a cost segregation study. Specialized plumbing, cabinetry, flooring, and electrical systems can be reclassified from 39-year to 5- or 15-year property.
