Cost Segregation in 2026: What Property Owners Need to Know

If you own income-producing real estate, you already know your property depreciates over time. But there's another question worth asking:

Are you recovering that depreciation on the right timeline?

Without a detailed analysis, much of a property's depreciable basis may remain assigned to the building's standard recovery period, generally 27.5 years for residential rental property or 39 years for nonresidential real property.

A cost segregation study takes a closer look at what is actually inside the building. And for many property owners, that closer look can reveal an opportunity to access eligible depreciation sooner.

What Is Cost Segregation?

A building may look like one asset. From an engineering perspective, it isn't. It contains flooring, electrical systems, lighting, millwork, equipment, exterior improvements, specialized systems and many other individual components.

A cost segregation study analyzes those components to determine whether certain assets can appropriately be classified into shorter depreciation recovery periods, such as 5, 7 or 15 years, rather than remaining entirely within the building's 27.5- or 39-year recovery period.

The goal isn't to create new depreciation. It's to identify when eligible depreciation can properly be recovered.

Why Does Timing Matter?

Imagine that a portion of the depreciable basis currently sitting inside a 39-year building classification can properly be identified as shorter-life property. Instead of recovering that portion gradually over decades, eligible deductions may become available earlier.

Earlier deductions → Lower near-term taxable income → More capital available sooner

For a property owner or investor, capital available today could potentially be used to:

• Reinvest in the portfolio
• Fund improvements
• Reduce debt
• Support operations
• Pursue another acquisition

The specific tax impact varies by property and taxpayer, but the underlying idea is simple:

Same property. Same underlying depreciable basis. Different timing.

Why Is Cost Segregation Relevant in 2026?

2026 is an important year for property owners to revisit their depreciation strategy. Changes enacted in 2025 restored 100% bonus depreciation for certain qualified property acquired after January 19, 2025, subject to applicable requirements. That can make the classification of eligible shorter-life assets particularly relevant.

But there's an important distinction: cost segregation ≠ bonus depreciation. Cost segregation identifies and classifies the components of a property. Bonus depreciation is a separate tax provision that may allow certain qualifying assets to be depreciated more rapidly. Not every component identified through cost segregation automatically qualifies for 100% bonus depreciation.

What Properties May Be Good Candidates?

Cost segregation can potentially apply across many types of income-producing real estate, including:

• Multifamily
• Office
• Retail
• Hotels
• Restaurants
• Medical Facilities
• Industrial Properties
• Warehouses
• Self-Storage
• Short-Term Rentals

But property type alone doesn't determine whether a study makes sense. Factors such as the property's depreciable basis, acquisition or construction date, improvements, asset composition and tax circumstances can all affect the potential opportunity.

That's why we believe the better question isn't “Does my type of property qualify?” It's “Is my specific property worth analyzing?”

How Does a Cost Segregation Study Work?

At SegPoint Engineers, the process begins with the property — not with assumptions.

1. 1
   Property Review

   We review key property information and determine whether there appears to be a meaningful opportunity.

2. 2
   Engineering Analysis

   Our team analyzes the property's components, available documentation and relevant costs.

3. 3
   Asset Classification

   Eligible components are identified and assigned to the appropriate recovery periods based on applicable depreciation rules.

4. 4
   Cost Allocation

   The property's depreciable basis is allocated among the appropriate asset categories.

5. 5
   Final Report

   The findings are documented in a detailed cost segregation study that the property's CPA can evaluate for tax implementation.

SegPoint Engineers handles the engineering analysis and documentation. Your CPA determines the taxpayer-specific tax treatment and implementation.

When Should You Consider Cost Segregation?

There are several moments when it may be worth reviewing a property:

• You recently purchased a property.
• You completed new construction.
• You made significant renovations or improvements.
• You're expanding your real estate portfolio.
• You own a property that has never had a cost segregation study.

And that last one matters. Purchasing a property several years ago does not necessarily mean the opportunity is gone. There are circumstances where a look-back cost segregation study may be possible — something we'll cover separately in the Learning Hub.

So, Is Cost Segregation Worth It in 2026?

The answer shouldn't automatically be yes. A good cost segregation provider should first determine whether the potential opportunity appears meaningful enough to justify a full study. Because cost segregation isn't about generating the biggest possible number.

It's about properly identifying what's inside the property and understanding when eligible depreciation can be recovered. And in 2026, that is a question worth asking.
