What is Cost Segregation?
Cost Segregation is a strategic approach to accelerate depreciation and enhance your property's tax benefits through engineering analysis. We do this by analyzing the costs of a commercial or income-producing property and putting them into specific asset categories.Ā
In traditional methods, an entire commercial building or income-producing property would be treated as one individual long-term asset that depreciates over several years. Commercial buildings depreciate over 39 years and other income-producing properties, 27.5.Ā
A Cost Segregation Study identifies separate components that have the ability to be depreciated within much shorter time frames. Typically, these components can be depreciated at 5, 7, or 15 years.

Strategic Tax Planning
Cost segregationĀ is a strategic federal income tax tool that enhances near-term cash flow byĀ accelerating depreciation deductionsĀ and deferring taxes. By identifying and reclassifying building components, property owners can maximize tax savings in the early years of ownership, often achievingĀ $50,000 to $1M+ in first-year tax savings.

The Ultimate Tax Saving Strategy

Invest Smarter: How Deferred and ETS Are Simplifying the 1031...

Tax Plan IQ Power Hour - Cost Segregation
Apr 2025
Bonus Depreciation Is Back at 100%
Bonus depreciation has been fully restored! This creates one of the most powerful tax opportunities available to real estate investors and business owners.
You can once again deduct 100% of the cost of qualifying property in the same year itās placed in service. That means faster write-offs, stronger cash flow, and more capital to reinvest into your business.
What It Means for You
Non-structural interior improvements
Furniture, fixtures, and equipment (FF&E)
Land improvements such as parking lots and landscaping
Why it Matters
This restoration lets investors accelerate depreciation and fully deduct qualifying assets, creating immediate tax savings and cash for reinvestment.
Timing is Key
100% bonus depreciation applies to property acquired after January 19, 2025, and placed in service before 2030. Now the ideal time to act during this five-year window.

Frequently Asked Questions
What is included in cost segregation?
A cost segregation study surveys your building's subcomponents, like lighting fixtures, heating and air conditioning systems, and other components that deteriorate over time. It assigns five- or 15-year lifespans to these subcomponents. Then the study assesses how much in taxes you can write off because of your financial loss from these aging subcomponents.
How much should a cost segregation study cost?
It should cost between $3,000-$12,000. However, the capital outlay is more than worth it, considering you can save hundreds of thousands, if not millions, in taxes by commissioning a study. The ROI is amazing.
What is the best time of the year to do a cost segregation study?
Anytimeāas long as you commission your cost segregation study before a construction rehab. Because cost segregation sets a baseline for the original purchase, it's easier for us and the IRS to set that baseline by performing the study before the rehab, with an engineer documenting the reclassification, before the improvements are made.
Are cost segregation studies worth it?
Definitely! The 2025 One Big Beautiful Bill Act allows for an immediate deduction for the full costs in the first year. If you own a property with a class life of 27 years, you might be eligible for a sizeable bonus depreciation in year one by reallocating some of your building's assets to a five- or 15-year lifespan.
What types of properties qualify for cost segregation?
Most commercial and investment properties qualify, including office buildings, retail spaces, industrial facilities, apartments, hotels, medical facilities, and warehouses. Properties must have been built, purchased, or substantially renovated after 1986 to qualify.
How long does a cost segregation study take?
The typical timeline is 4-6 weeks from start to finish. This includes the initial property inspection, engineering analysis, and final report preparation. Larger or more complex properties may require additional time.
Can I do a cost segregation study on a property I've owned for several years?
Yes, through a 'look-back' study. You can claim missed depreciation from prior years without amending tax returns by filing Form 3115. This allows you to take advantage of accelerated depreciation even on properties owned for several years.
What documentation is needed for a cost segregation study?
Typically, we need property purchase documents, construction drawings if available, depreciation schedules, and renovation records. However, our engineering-based approach can still deliver results even with limited documentation.
How does bonus depreciation affect cost segregation benefits?
Bonus depreciation allows for immediate expensing of qualified property. Through 2023, 80% bonus depreciation is available, phasing down to 60% in 2024, 40% in 2025, and 20% in 2026. This significantly enhances the benefits of cost segregation studies.
Will a cost segregation study trigger an IRS audit?
No, a properly conducted cost segregation study should not trigger an audit. Our engineering-based approach follows IRS guidelines and provides thorough documentation to support all classifications and calculations in case of an audit.
