If you own Texas rental property, depreciation can become one of your most valuable tax deductions, yet the standard timeline can feel frustratingly slow. Residential rental buildings generally follow a 27.5-year recovery period under MACRS, so a substantial portion of your investment gets deducted gradually over many tax years. That long recovery period can limit the size of your early deductions, which is where cost segregation can become particularly valuable.
A cost segregation study can change the timing for qualifying components because it separates certain shorter-lived assets from the building itself. When those assets qualify for accelerated depreciation, you can potentially claim much larger deductions during the early years of ownership, potentially improving your federal tax position when you need the cash flow most.
What a cost segregation study examines
A Texas cost segregation study examines the components that make up your rental property, then classifies qualifying costs according to their appropriate federal depreciation periods. A qualified study typically considers construction records, invoices, property plans and the physical characteristics of the building, so the resulting allocation has a defensible basis.
Certain appliances, carpeting and furniture used in residential rentals generally fall into a five-year class, while qualifying roads, fences and shrubbery can fall into a 15-year class. Your building itself generally remains on the 27.5-year schedule, so the study focuses on identifying costs that legitimately qualify for faster recovery.
How accelerated depreciation works
The benefit comes from recovering qualifying costs over shorter periods, moving deductions closer to the year when you purchase or improve the property. Those costs follow their respective MACRS schedules rather than remaining part of the building’s 27.5-year recovery period. The distinction matters for rental property tax planning, since earlier deductions can reduce taxable income during the initial ownership period. Your actual deduction depends on the property’s basis, classification, placed-in-service date and your broader tax circumstances.
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.
Passive activity limits can affect the benefit
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.
For the underlying statutory framework, the Internal Revenue Code’s passive-activity rules provide the relevant definitions and limitations.
What bonus depreciation means under current law
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.
That change matters for cost segregation because qualifying five-year and 15-year property can fall within the category of tangible MACRS property eligible for the additional first-year depreciation deduction. The result can be a substantial first-year deduction when qualifying components are identified and the applicable requirements are met.
For certain eligible property placed in service during the first tax year ending after January 19, 2025, a taxpayer can make a one-time election to deduct 40% instead of the 100% additional first-year depreciation deduction. The applicable rules also provide a 60% rate for certain longer-production-period property and certain aircraft. IRS Notice 2026-11 provides interim guidance on this election and the amended bonus depreciation rules.
The relevant legislation is Public Law 119-21, which amended Section 168(k).
Depreciation recapture needs to be considered
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.
For the underlying recapture provisions, see IRC Sec. 1245 and IRC Sec. 1250.
This means the value of a study cannot be judged solely by the size of the first-year deduction. You also need to consider how the accelerated deductions interact with your expected holding period, future taxable income and eventual disposition.
Why Texas owners should consider the bigger picture
Texas has no individual state income tax, so the immediate benefit of cost segregation for many individual rental owners comes primarily through federal taxation. That makes federal depreciation planning particularly relevant when you acquire a property with substantial qualifying components.
You should still consider how your ownership structure affects the outcome, since an individual owner, partnership or corporation can face different tax considerations. Passive activity limitations, material participation, depreciation recapture and your ability to use the resulting deductions can all affect the actual value of accelerating depreciation.
When a cost segregation study makes sense
A cost segregation study can deserve serious consideration when you have purchased a higher-value rental property, completed substantial improvements or expect enough taxable income to benefit from accelerated deductions. The strategy does not create additional economic value in your property, since it changes the timing of deductions for qualifying assets.
You also need a properly supported analysis, since an aggressive allocation can create problems if the classifications cannot withstand IRS scrutiny. If your property and tax position fit the strategy, a study can bring substantial deductions forward, so you can potentially retain more cash during the early years of ownership and make your rental investment tax profile more efficient.
