When you own a Texas multifamily property, your depreciation schedule can make the building look like a single asset; however, tax rules can treat individual components differently. A detailed study examines those components, so you can see which costs fit shorter recovery periods.
That distinction matters because residential rental property generally uses a 27.5-year recovery period under the Modified Accelerated Cost Recovery System. Qualifying assets can fall into five-year or 15-year categories, so separating eligible costs can accelerate deductions connected with your investment.
For a multifamily owner, the process can feel technical, but the underlying idea is practical. You are looking at what you purchased, how each component functions and which tax classification fits. The analysis can give your tax adviser useful depreciation documentation.
What a study reclassifies
Cost segregation in Texas applies federal tax rules to specific assets within your property. The analysis does not create a special Texas depreciation system. Instead, it identifies portions of your depreciable basis that qualify for shorter recovery periods under MACRS.
For a residential rental property, the building generally falls into the 27.5-year category, while appliances, carpeting, furniture, site improvements and other qualifying assets have shorter recovery periods. IRS guidance lists appliances, carpeting and furniture used in residential rentals as five-year property.
The potential benefit comes from timing, so a larger deduction earlier in ownership can affect taxable income, cash flow and investment planning. Current federal law also provides a 100% additional first-year depreciation deduction for qualifying property acquired and placed in service after January 19, 2025, subject to the applicable requirements.
Consider a Texas investor who acquires a residential rental property for $3,150,000, of which $450,000 is allocated to land, leaving a depreciable building basis of $2,700,000. The investor separately purchases $65,000 of furniture, fixtures and equipment. The property is placed in service in January. Without a cost segregation study, the building is depreciated over 27.5 years and the first-year deduction under the mid-month convention is $94,095; the separately purchased FF&E receives 100% bonus depreciation of $65,000 whether or not a study is performed, for a total of $159,095. With a study, $378,000 is reclassified to five-year personal property and $243,000 to 15-year land improvements, giving $621,000 of accelerated basis eligible for 100% bonus depreciation. The remaining $2,079,000 stays on the 27.5-year schedule and produces $72,453 in year one. Adding the $65,000 of FF&E, the first-year deduction is $758,453. The study’s incremental contribution is $599,358, which at a 37% marginal federal rate defers roughly $221,762 of tax.
Land improvements around a multifamily property
Land improvements deserve close attention because land itself is not depreciable, while qualifying improvements attached to or associated with the site can be depreciable. For an apartment community, those costs can include roads, sidewalks, fences, landscaping and similar site features.
The IRS classifies certain improvements made directly to land or added to it as 15-year property under GDS. That classification can create a difference when your property contains extensive parking areas, pedestrian routes, fencing, landscaping or other site infrastructure supporting residents.
An engineering-based study examines actual components, so classification reflects your property’s construction details rather than a broad estimate. Your report can connect costs to specific assets, giving your tax professional better documentation for depreciation treatment reported on your tax return.
Five-year property inside multifamily buildings
Five-year property can represent an important category within multifamily projects because residential rental activities can include appliances, carpeting and furniture that receive a five-year recovery period. Those items can appear throughout individual units, common areas, leasing offices or operational spaces.
The classification depends on applicable tax rules and the nature of the asset, so you cannot assume that every item inside an apartment receives a five-year life. An engineering review helps distinguish personal property from building components that fit longer-lived classifications.
This distinction can become useful when you acquire an existing apartment complex with substantial interior finishes or equipment, so the purchase price contains costs connected with different assets. A detailed study can identify those costs and assign them to defensible recovery categories.
What an engineering-based study examines
An engineering-based study goes deeper than applying a percentage to the purchase price, so the process can involve construction documents, plans, invoices, specifications, photographs, inspections and records. The IRS describes cost segregation as fact-intensive, involving tax law and engineering analysis.
Engineers can examine how a component was installed, its function, where it sits inside the property and how it relates to the building structure. Those details matter because tax classification depends on the property’s facts, so physical inspection can strengthen the analysis.
The IRS also recognizes that some cost segregation examinations require specialists with engineering, construction, industry or specialized training. For you as an owner, that means analysis quality matters; your depreciation position should connect each reclassified asset with supporting evidence.
Building systems that require careful classification
Multifamily properties contain electrical, plumbing, heating, cooling, fire protection, security and telecommunications systems, so classification can become complicated. Some components can qualify for shorter recovery periods, while structural elements and core building systems generally remain in longer-lived property categories.
A study therefore examines function as well as location, so two components within the same area can receive different treatment. For example, removable property serving an apartment’s occupants can have a different recovery period from materials forming part of the building structure.
That level of detail matters when your property has been renovated, expanded or constructed with specialized features; underlying costs can span several different tax asset categories. Good supporting records help you understand why each component received its assigned tax classification.
Passive activity limits and the timing of deductions
The tax benefit from accelerated depreciation depends on whether you can actually use the resulting deductions. The passive activity rules can limit that benefit, so the classification analysis needs to be considered alongside your broader tax position.
These deductions are not automatically usable. Under IRC Sec. 469, rental real estate is generally a passive activity, and passive losses offset only passive income; unused losses are suspended and carried forward until the taxpayer has passive income or disposes of the activity in a fully taxable transaction. A taxpayer who qualifies as a real estate professional under Sec. 469(c)(7) and materially participates may treat the losses as non-passive. Separately, a rental with an average guest stay of seven days or less is not a rental activity under Reg. Sec. 1.469-1T(e)(3)(ii)(A), so material participation alone can make the losses non-passive without real estate professional status.
These rules mean the size of a first-year deduction does not necessarily equal the immediate tax saving. Your income, participation, property use and other circumstances can affect when the deduction becomes usable.
Depreciation recapture and current law
Accelerated depreciation also needs to be considered alongside the tax consequences of a future sale. The shorter recovery period can move deductions into earlier years, but some of that benefit can be reflected in the treatment of gain when you dispose of the property.
Accelerated depreciation is a deferral, not forgiveness. On a taxable sale, depreciation claimed on the five- and 15-year property a study reclassifies is recaptured under IRC Sec. 1245 as ordinary income to the extent of depreciation taken, potentially at rates up to 37%, rather than the 25% maximum applying to unrecaptured Sec. 1250 gain on the building itself. A study therefore shifts part of future gain from Sec. 1250 to Sec. 1245 treatment. The net benefit depends on the time value of the deferral and the expected holding period, and is generally weaker for property expected to be sold within a few years.
The timing of bonus depreciation also changed under recent federal legislation.
The One Big Beautiful Bill Act (P.L. 119-21), signed July 4, 2025, made the 100% first-year bonus depreciation rate under IRC Sec. 168(k) permanent for qualifying property acquired and placed in service on or after January 20, 2025. Before that change, the rate was phasing down on a fixed schedule of 80%, 60%, 40%, 20% and then 0%. Property acquired before January 20, 2025 remains subject to the phase-down percentage in effect at the time of acquisition.
For a Texas multifamily owner, that makes the date of acquisition and placement in service important when assessing the potential value of reclassification. A study can identify eligible shorter-lived property, but the applicable bonus depreciation rules and your individual tax circumstances determine how much of that basis can generate an accelerated deduction.
A supported study therefore gives you more than shorter recovery periods; it creates a documented connection between construction costs, asset classifications and depreciation rules. For a Texas multifamily property, that detail can help you make informed current tax decisions.
