Consider a hypothetical dental group that has just finished building a new clinic. They’ve put capital into everything: custom cabinetry, lead-lined imaging rooms, specialized plumbing, the works.
But the full buildout was being depreciated over 39 years, treated as standard commercial real estate. Asked why they hadn’t done a cost segregation study, the answer was typical: “We didn’t think dental clinics qualified.”
That assumption could have cost them. A detailed engineering-based study might reclassify roughly 30% of a buildout like this into 5- and 15-year property, moving a large share of the deductions into the first year. The worked example below shows the math.
Dental clinics are often good candidates for cost segregation because they contain a high volume of short-lived building components. If you’ve built, renovated, or purchased clinic space, it’s worth checking whether a study makes sense.
Here’s how cost segregation works, and why it often fits dental practices.
Key Components in Dental Clinics That Drive Depreciation Acceleration
What makes a dental clinic a good fit for cost segregation is the density of short-lived components built into the property. Unlike a typical office building, dental clinics require extensive customization, much of which can be separated from the building’s core structure and depreciated over shorter timeframes.
Common reclassifiable components include:
- Specialty electrical and plumbing: Operatories, sterilization centers, and imaging rooms often require dedicated electrical circuits and plumbing serving specific equipment. These improvements are often eligible for 5- or 15-year depreciation.
- Interior buildouts: Millwork, cabinetry, lead-lined walls, removable specialty flooring, and decorative or accent lighting are good candidates for accelerated treatment.
- Tenant improvements: Many dental clinics lease their space and pay for the buildout. Interior improvements may qualify as qualified improvement property (QIP), which is 15-year property eligible for bonus depreciation, and a study can separate shorter-life components.
- Dental equipment: Exam chairs, delivery units, imaging systems, vacuum pumps, and X-ray machines are the practice’s equipment. They’re depreciated separately on their own schedules rather than reclassified out of the building, so a study focuses on the building and its improvements.
In a well-documented study, reclassified components typically comprise 27% to 42% of the depreciable basis on a medical or dental office property, which can produce large first-year deductions. The lower end is the baseline result and the upper end is what an optimized study produces on a clinic with a heavy specialty buildout. For benchmarks across other property types, see our guide to typical reclassification percentages.
Tax Rules and Bonus Depreciation Relevant for Dental Clinics
Dental practice owners can take advantage of several accelerated depreciation tools, especially in light of recent legislative changes.
- Modified accelerated cost recovery system (MACRS) classification: Assets like equipment, custom finishes, and land improvements can be depreciated over 5, 7, or 15 years, far shorter than the standard 39-year schedule.
- 100% bonus depreciation: Under the One Big Beautiful Bill Act, 100% bonus depreciation is permanent for qualifying property acquired and placed in service after January 19, 2025. This allows clinics to deduct 100% of eligible costs, such as 5- and 15-year building components and qualifying interior improvements, in the first year.
- Section 179: Clinics can also expense up to $2.5 million of qualifying purchases for 2025 (indexed for inflation after that), a useful complement to bonus depreciation for smaller investments.
- Grouping elections and self-rental: For dentists who lease their building to their own practice, proper structuring can preserve cost segregation benefits. Done incorrectly, the self-rental rules can leave the losses trapped as passive.
- Catch-up depreciation: Clinics that missed opportunities in prior years may still benefit through a one-time adjustment, often without needing to amend past returns.
What Reclassification Can Look Like in Practice
When a dental clinic invests in building or renovating a facility, the potential for accelerated depreciation can be substantial. Take, for example, a 4,800-square-foot clinic in a medical plaza with $1.6 million of depreciable building cost, excluding land and the practice’s movable equipment.
A cost segregation analysis might identify roughly $430,000 to $670,000 of that cost (27% to 42%) as 5- and 15-year property. These often include items like cabinetry, millwork, dedicated electrical and plumbing for equipment, accent lighting, and site improvements.
If the clinic was acquired and placed in service after January 19, 2025 (for a new build, generally when construction begins), it could deduct 100% of those costs in the first year. At a 37% rate, that’s roughly $160,000 to $249,000 in tax savings, if the deduction can be used. Those savings could go toward hiring, expanding services, or paying down debt.
The result depends on the details: each component’s classification determines how much of the cost moves into shorter recovery periods.
Risks, Costs, and What to Watch Out For
Cost segregation offers real tax benefits, but like any strategy, it comes with considerations:
- Study cost: A fully engineered study starts at $2,730 for commercial property and $2,320 for residential, with a Rapid Report option from $950. Larger clinics, multi-site practices, and buildings with specialized systems price above those starting points. Against the baseline savings in the example above, that’s roughly 58 times the $2,730 starting fee.
- Audit risk: Cost segregation is an accepted method, documented in the IRS Cost Segregation Audit Techniques Guide, but aggressive classification without documentation can lead to scrutiny. Working with credentialed professionals who document their methodology is key.
- Depreciation recapture: On future sale, accelerated depreciation may increase the recapture tax owed. However, the time value of money generally still favors early deductions, especially if reinvested effectively.
- Suitability: Clinics with minimal buildouts or leased equipment may not see meaningful gains. A brief feasibility analysis can quickly determine ROI potential.
How to Implement Cost Segregation in Your Dental Clinic
A successful study begins with planning. Here’s how to approach it:
- Engage early: Ideally, start the process during construction or just after purchase. But retroactive studies can also be valuable.
- Provide documentation: Blueprints, contractor invoices, depreciation schedules, and equipment lists are crucial inputs.
- Choose the right team: Look for firms that combine tax expertise with engineering acumen. Avoid firms that rely solely on templates or rule-of-thumb calculations.
- Evaluate the numbers: Many reputable providers offer free feasibility assessments that are helpful for gauging whether savings will meaningfully outweigh the study cost.
How Tax Savings Translate Into Operational Growth
The value of cost segregation isn’t just in the tax deduction; it’s in what that deduction enables. By accelerating depreciation, dental clinics can increase first-year deductions and, if they can use them, improve cash flow.
Practices commonly use the savings for:
- Adding operatories or expanding to additional locations
- Upgrading diagnostic imaging and sterilization systems
- Increasing compensation or hiring clinical support staff
- Paying down equipment loans or lines of credit faster
Beyond the upfront cash, there’s also a planning benefit: more accurate asset tracking allows for better forecasting of future capital needs, replacements, and tax positioning. For growing clinics, that kind of clarity can be as important as the savings themselves.
Final Thoughts on Whether Cost Segregation Is Right for Your Clinic
For dental clinics with meaningful investment in property and buildouts, cost segregation can be a valuable tax strategy. The key is knowing when the numbers pencil out and having the right professionals guide the process.
If you’re considering cost segregation for a dental clinic, it’s worth speaking to a firm that specializes in this work. R.E. Cost Seg provides engineering-based studies for healthcare and dental properties, starting with a feasibility analysis of whether a study makes sense for your clinic.
