Cost segregation
Cost segregation studies.
Move deductions forward.
Transform one slow depreciation schedule into a component-level strategy engineered around how your property was actually built.
39years→5years
What a cost segregation study actually does.
When you buy or build a commercial or rental property, the tax code treats the whole thing as one asset and lets you deduct its cost slowly: over 39 years for commercial buildings, 27.5 for residential rentals. Land is never deductible.
But a building is not one thing. Inside the purchase price are carpets, cabinetry, specialty lighting, dedicated electrical for equipment, decorative finishes, parking lots, fencing and landscaping. The tax code already allows those items to be depreciated over 5, 7 or 15 years. They are simply buried in the single building number on your depreciation schedule.
A cost segregation study is an engineering-based analysis that finds those components, assigns each a supportable cost, and documents why it belongs in a shorter recovery period. Your CPA then depreciates each class on its own schedule. The result is a larger deduction in the early years of ownership, which lowers taxable income now and frees cash for the next investment.
It does not create new deductions out of thin air. It changes when you take deductions you were always entitled to, which is why the timing of your purchase, your tax rate and your plans for the property all matter.
What gets reclassified
Four buckets instead of one.
- Office furniture and fixtures
- Certain telecommunications and data systems
- Specialty process or trade equipment
- Some agricultural and industrial assets
- Parking lots, curbs and sidewalks
- Site lighting and signage foundations
- Fencing, retaining walls and gates
- Landscaping, irrigation and drainage
- RV pads, utility pedestals and site utilities
- Swimming pools and outdoor amenities
- Structure, roof, foundation and exterior walls
- Base HVAC, electrical, plumbing and fire protection
- Elevators, stairs, windows and doors
- Everything that was not pulled into the shorter classes
Classification follows the applicable asset guidelines and case law; what qualifies depends on function and use, not just the item’s name. Bonus depreciation may apply to the 5-, 7- and 15-year classes when eligibility rules are met.
What the numbers look like.
A hypothetical $1,000,000 multifamily purchase, placed in service this year, with $200,000 allocated to land. The same assumptions as our online calculator.
| Scenario | Depreciable basis | Short-life allocation | First-year deduction |
|---|---|---|---|
| Straight-line only (27.5 years) | $800,000 | 0% | ≈ $29,000 |
| With a cost segregation study | $800,000 | 25% ($200,000) | ≈ $226,000 |
| Additional first-year deduction | ≈ $197,000 | ||
| Potential federal tax effect at a 32% rate | ≈ $63,000 |
The study moved a quarter of the building cost into 5-, 7- and 15-year property. With 100% bonus depreciation available for qualifying property acquired after January 19, 2025, that reclassified cost can be deducted in the first year rather than over decades. The “tax effect” is the deferral an owner could realize if the deduction is fully usable against income taxed at that rate.
Illustrative only. Actual allocations come from the engineering analysis of your property; usable deductions depend on basis, passive activity, at-risk and excess business loss limits, and your CPA’s review. A study is not a tax opinion.
Where studies tend to find the most.
Properties with more finishes, equipment and site work reclassify more. These ranges reflect common industry experience, not a promise for your building.
Pads, pedestals, roads, pools and site utilities are mostly land improvements.
Kitchens, décor, specialty lighting and extensive finishes.
Dedicated plumbing, gas, electrical and cabinetry for equipment.
Unit finishes, appliances, parking, landscaping and amenities.
Fixtures, signage, lighting and site improvements.
Finishes, millwork and tenant-specific systems.
Process power, specialty equipment and yard improvements.
Site work, security, gates and partitions.
When it may fit
You purchased an investment or commercial property recently—or years ago and never completed a study. Prior years can often be caught up through an accounting method change.
You completed ground-up construction and have detailed costs ready to be analyzed.
You renovated, expanded, or replaced major components and need the old and new assets properly treated, including a review under the tangible property regulations.
You are designing a new project and want tax and energy strategy considered before decisions are locked in.
Evidence over estimates.
We connect tax classification to construction facts.
- 01Feasibility
Review basis, land, placed-in-service timing, tax posture, and available records.
- 02Engineering analysis
Examine drawings, cost data, property condition, systems, finishes, and site improvements.
- 03Tax classification
Map components to applicable recovery periods and document methodology and authority.
- 04Implementation
Deliver schedules and workpapers designed for coordination with your CPA, including prior-year method-change needs where applicable.
Innovate Real Estate Tax Strategies does not provide legal advice. Final tax positions should be evaluated with your independent tax advisor.
The practical questions, answered up front.
Most studies are delivered four to eight weeks after we receive your documents, depending on property complexity and whether a site visit is needed. Tell us your filing date and we schedule around it.
Your free proposal includes a written, fixed fee for the study, quoted before you commit. The fee reflects the property’s size, complexity and available records, and it never changes based on the result. A feasibility review is always free.
Closing statement or construction cost detail, your current depreciation schedule, a supported land allocation, placed-in-service date, and any plans, appraisals or renovation invoices you have. We identify the gaps.
An engineering report with methodology and photos, component-level asset schedules by recovery period, the workpapers your CPA needs to implement, and support if questions arise later.
