One of my clients is a healthcare group expanding its footprint with a new 40,000-square-foot specialty clinic. The CFO had done his homework on 179 deductions and depreciation schedules, but when I brought up cost segregation, he admitted he hadn’t considered it. 

I got to work, and within two weeks, we had identified over $1.3 million in assets that could be reclassified and depreciated in the first year.

In the healthcare sector, where facilities are complex, capital-intensive, and heavily regulated, cost segregation is often overlooked. With 100% bonus depreciation restored for property acquired and placed in service after January 19, 2025, it’s worth evaluating for healthcare property owners and operators.

In this article, I’ll break down how cost segregation applies to healthcare facilities and what to expect from a study.

What Cost Segregation Means for Healthcare Facilities

Cost segregation is a method of accelerating depreciation on parts of a building that wear out more quickly than the building itself. Instead of writing off the entire building over 39 years (the default for commercial property), you break out certain components, like flooring, lighting, plumbing, and specialized equipment, and depreciate them over 5, 7, or 15 years.

Medical buildings are not like standard office buildings. They’re filled with highly specialized equipment, custom wiring, modular partitions, sterilization units, and patient-focused infrastructure. All of that may qualify for shorter depreciation periods if properly identified through a cost segregation study.

Accelerating those write-offs can reduce taxable income in the early years, if the owner can use the deductions. Owners who lease the building to their own practice through a separate entity should check the self-rental rules first.

What Can Be Reclassified? A Look Inside the Walls

In a healthcare facility, many assets can be reclassified. Here’s what typically qualifies:

• Medical equipment: MRI machines, imaging suites, surgical lighting, autoclaves, and lab installations
• Specialized electrical and plumbing: Think about lead-lined walls, oxygen piping, or electrical circuits for radiology
• Interior finishes: Vinyl flooring in exam rooms, wall paneling, cabinetry, nurse stations, and even waiting room fixtures
• Tenant improvements: Custom build-outs for leased spaces (e.g., outpatient clinics or dental offices)
• Site work: Parking lots, sidewalks, signage, lighting, and landscaping often qualify for 15-year depreciation

These elements are foundational to how a medical facility operates, and they depreciate far faster than concrete walls or steel framing.

When to Consider a Cost Segregation Study

Timing affects how easily a study can be done and when the deductions land. In healthcare, that depends on what stage you’re at with your facility. Whether you’re breaking ground, buying an existing building, or retrofitting an aging space, accelerated depreciation may be available; the stage you’re at decides when to run the study.

Here are the best moments to consider a study:

• Right after new construction is completed
  If you’ve just built a new hospital, clinic, or outpatient center, a cost segregation study allows you to break out the assets immediately, before the first tax return is filed.
• When acquiring an existing medical property
  Buying a building? Even if it’s not new, you can analyze the purchase price and reallocate portions of it (e.g., electrical systems, finishes, site improvements) to shorter depreciation schedules.
• After major renovations or build-outs
  Healthcare facilities constantly evolve. If you’ve invested significantly in updated equipment, tenant improvements, or medical-specific infrastructure, those updates may be depreciated faster through a study.
• If your project is still in design or under construction
  By involving a cost segregation provider early, you can track and separate costs properly, ensuring that things like gas lines, custom lighting, and specialty flooring don’t get lumped into the 39-year bucket.
• Even years after the building is already in use
  Haven’t done a study yet? You’re not out of luck. The IRS allows retroactive cost segregation through a change in accounting method (Form 3115). You can claim missed depreciation from previous years without amending past returns.

Real-World Financial Impact: A Hypothetical Case Study

Let’s say you’re building a $5 million outpatient surgical center. You’ve got imaging rooms, lead-lined walls, dedicated HVAC zones, specialty plumbing, lab space, and high-end interior finishes. Most of this falls into the category of assets that wear out far faster than the shell of the building, and that’s where cost segregation comes in.

Assume the full $5 million is depreciable building cost, and a study reclassifies 35% of it into 5-, 7-, or 15-year property, inside the typical 27–42% range for medical buildings. That’s $1.75 million you don’t have to stretch out over four decades.

Under 100% bonus depreciation, for property acquired and placed in service after January 19, 2025 (for a new build, generally when construction begins), you could write off that $1.75 million in full in Year One. At a 37% rate, that’s about $648,000 of federal tax, or about $368,000 at the 21% corporate rate, if you can use the loss.

If your facility is already built, a look-back study can capture the missed depreciation this year without amending prior returns. The catch-up uses the bonus rate from the year the property was originally placed in service, so it may be smaller than a 100% deduction.

Final Thoughts: Work with a Partner Who Knows Healthcare

Cost segregation moves depreciation into earlier years, which can lower taxes when owners can use the deductions. With 100% bonus depreciation restored, it’s worth evaluating for any healthcare property you’ve built, bought, or renovated.
