Cost Segregation for Dental Practices: Tax Savings for Buildouts, Renovations, and Acquisitions

Key Takeaways

• A cost segregation study can create $30,000 to $200,000 in federal tax benefits for every $1 million a dental practice spends on new space, renovation, or new construction.
• Renovations tend to unlock the largest share of accelerated depreciation because so much of the work touches shorter-lived building components, such as dental chairs, medical gas lines, and specialty electric systems.
• Leased space qualifies too, not just owned buildings. A dentist who leases space and builds out the interior can often depreciate those improvements as 15-year qualified improvement property, which is generally eligible for 100% bonus depreciation.

Why Dental Practices Should Consider Cost Segregation

A dentist who signs a new lease, buys an existing practice, or renovates an operatory rarely thinks about depreciation schedules in the same breath as dental chairs and sterilization equipment. But that oversight can be costly. Cost segregation, an engineering-based analysis that identifies and reclassifies building components into shorter-lived tax categories, can turn a routine buildout into a substantial source of near-term cash flow.

With the One Big Beautiful Bill Act making 100% bonus depreciation permanent for qualifying property acquired after January 19, 2025, cost segregation can give dental practices significant upfront benefits. Reclassified components can be deducted in the year the practice spends the cash, which helps ease the cash flow strain of a buildout or acquisition.

How Cost Segregation Helps Dental Offices Accelerate Depreciation

Cost segregation works by breaking a building down into its individual components and reclassifying the ones that qualify into five-year, 15-year, or Qualified Improvement Property (QIP) categories instead of the standard 39-year schedule for commercial real estate. Front-loading depreciation this way puts the time value of money to work for the practice rather than the IRS.

For dental offices specifically, engineers commonly move the following into shorter-lived categories:

• Dental chairs
• Hydraulic, medical vacuum, and air piping to dental chairs
• Medical gas installation
• Specialty electric and wiring
• Carpet and vinyl flooring
• Wallpaper and window treatments
• Crown molding and custom millwork
• Counters and cabinets
• Decorative lighting
• Fire extinguishers
• Security systems

Land improvements, such as landscaping, paved parking lots, sidewalks, and exterior decorative lighting, may also qualify for shorter depreciable lives.

A cost segregation study can also open the door to related strategies. When a project involves a fit-out or renovation, bonus-eligible QIP often comes into play. The Tangible Property Regulations may apply in renovation scenarios, and energy-efficient construction or retrofits may qualify for deductions under IRC Sec. 179D.

Cost Segregation Tax Savings Examples for Dental Offices

The scale of the opportunity depends heavily on the type of project. Three recent examples illustrate the range:

Dental office tenant space, acquisition. A tenant space in a plaza, including dental bays, consultation rooms, and a waiting room, was placed in service in October 2025 with a depreciable basis of $821,087. Engineers moved 30.4% of assets to the five-year category and 19.0% to the 15-year category, producing first-year tax savings of $143,310.

Pediatric dental office, new construction. A single-story, wood-framed building housing exam rooms, office space, breakrooms, and parking was placed in service in May 2026 with a depreciable basis of $1,890,645. Engineers moved 8.7% of assets to the five-year category and 25.4% to the 15-year category, producing first-year tax savings of $220,921.

Oral surgery center, renovation. A full renovation covering the reception area, offices, operatory suites, sterilization areas, and locker rooms was placed in service in August 2026 with a depreciable basis of $2,571,290. Engineers moved 54.8% of assets to the five-year category, 1.1% to the 15-year category, and 42.0% to QIP, producing first-year tax savings of $870,051.

The renovation example moved nearly ten times the share of assets into QIP compared with the other two, which is consistent with a broader pattern: acquisitions of existing space typically land on the lower end of the 15% to 30% range engineers generally see, while renovations often reach 40% to 80%.

When Dental Practices Should Get a Cost Segregation Study

The timing of a cost segregation study can affect how much benefit a practice sees. A practice that’s open for only part of the year, or that’s still operating at a loss, may not have enough income to absorb a large first-year deduction. In that case, it may make sense to adjust when the deductions are claimed. Whatever the timing, keep construction invoices, plans, and lease terms organized from the start. A study is easiest to complete when documentation is current, though it can often still be done after the fact.
