If you own commercial property — the building, not the lease — cost segregation can recover meaningful cash by accelerating depreciation on qualifying components. Jim is a CSSI National Account Executive. CSSI is the national leader: 60,000-plus studies, $55-plus billion in client tax savings, and a methodology that has never triggered an IRS audit when properly executed.
Standard depreciation: an entire building is depreciated over 27.5 years (residential rental) or 39 years (commercial). Cost segregation: an engineering team identifies and reclassifies qualifying components into 5, 7, or 15 year buckets. The reclassified components depreciate faster — meaning bigger deductions in the early years and recovered cash in your hands instead of the IRS's.
Carpeting, decorative lighting, specialty cabinetry, removable flooring, telecom wiring, computer-related equipment.
Office equipment and furniture, certain machinery, signage, decorative trim — the components a business genuinely uses up faster than the building shell.
Parking-lot striping, sidewalks, landscaping, fencing, exterior lighting, retaining walls, drainage.
In a typical study, 20% to 40% of a building's cost basis reclassifies into accelerated buckets. On a $1 million building that can mean $200K to $400K of accelerated deductions, much of it usable in the first year.
CSSI is the national leader in engineering-based cost segregation. The "engineering-based" part matters: an engineering study is the IRS preferred methodology and the methodology that holds up under audit. Estimates and rule-of-thumb percentages do not. CSSI studies have never triggered an IRS audit when properly executed.
More than any other firm in the United States. Two decades of methodology refinement.

Commercial real estate normally depreciates over 27.5 years (residential rental) or 39 years (commercial). That's a slow tax recovery on a property that may have a million-plus dollars of basis. An engineering-based cost segregation study reclassifies specific building components into 5, 7, and 15-year depreciation categories, which accelerates the deduction substantially in the early years of ownership.
Typical cost-segregation studies on a $1M-$5M commercial property reclassify 20-40% of basis into the shorter-life categories. The exact mix depends on building type, vintage, and use.
The savings depend on your marginal tax rate, your property's basis, and how much of the basis gets reclassified. A rough working number: on a $2M commercial property with 30% of basis reclassified into 5- and 15-year categories, accelerating depreciation can pull $150K-$300K of deduction into the first 5 years that would otherwise have been spread over 39. At a 30% combined federal/state rate, that's $45K-$90K of cash flow accelerated. Bonus depreciation rules can change these numbers materially.
You don't have to perform a cost-segregation study in the year you acquired the property. The IRS allows look-back studies via Form 3115 (Change of Accounting Method) that capture all the missed accelerated depreciation since acquisition in a single catch-up year. This can be a substantial one-time tax event for a property held 5-15 years without prior segregation.
CSSI is one of the older national cost-segregation firms — over 60,000 engineering-based studies completed since 2003, more than $55 billion in client tax savings delivered. Engineering-based studies (vs. rule-of-thumb estimates) survive IRS audits better and produce IRS-compliant documentation. CSSI's methodology has never triggered an IRS audit when properly executed. Jim is a CSSI National Account Executive, which means engagements run through him directly — not through a 1-800 line.

The CSSI engineering network also performs two adjacent federal tax services that frequently apply to the same property owners and businesses Jim serves through Steele Solutions. If you own commercial property or run a research-and-development-driven business, these can layer on top of cost segregation without conflict.
Section 179D of the Internal Revenue Code allows owners of qualifying commercial buildings to claim a deduction of up to $5.81 per square foot in 2026 (adjusted annually) for energy-efficient improvements to three building systems: interior lighting, HVAC and hot water, and the building envelope. The deduction is available for new construction, substantial renovations, and certain qualifying retrofits — and was made permanent and substantially expanded by the Inflation Reduction Act.
On a 50,000 square foot retail building with LED lighting, modern HVAC, and a tight envelope, 179D can deliver $100,000-$250,000 of first-year deduction. The study fee is dwarfed by the deduction.
The federal Research and Development tax credit (IRC §41) is a dollar-for-dollar reduction in federal income tax for qualifying research activities. Most businesses that engage in product development, software development, process engineering, prototyping, formulation work, or design iteration qualify — and most of them never claim it. Industry estimates suggest that businesses miss roughly 40% of their eligible R&D credits.
Industries that routinely qualify but rarely claim: small to mid-size manufacturers, custom fabricators, breweries and distilleries developing new products, software development shops, civil engineering firms, biotech and lab work, food and beverage formulation, and any business iterating on internal-use software with measurable technical uncertainty.
