Yes, retail properties are strong candidates for cost segregation. Strip centers, net lease buildings, pharmacies, quick-service restaurants and standalone storefronts carry parking lots, curbing, site lighting, landscaping, pylon signs, specialty electrical and tenant build-out items that can be examined as 5-year, 7-year and 15-year property instead of sitting on 39 years. With 100 percent bonus depreciation restored for property acquired and placed in service after January 19, 2025, those assets can generally be deducted in the first year. The catch is that retail income is usually passive, so the real question is who can use the deduction and when. Your CPA should confirm how these rules apply to your facts.
The default is to depreciate everything except land over 39 years, straight-line, mid-month convention. On a $4 million shopping center with a $3.2 million building basis, that produces roughly $82,000 a year, and it treats a parking lot, a storefront sign and a structural steel frame as if they all wear out at the same speed. The tax code does not require you to pretend that they do.
A fully engineered and accounted cost segregation study separates a property's cost into its components and assigns each one to the correct recovery class. The IRS describes the method in its own Cost Segregation Audit Techniques Guide. For background on how the IRS views the practice, our posts on what the IRS thinks about cost segregation and the IRS audit technique guide cover it in depth.
Retail produces favorable results for three reasons. It sits on large sites, so paving, drainage, site utilities, lighting, landscaping and signage are a bigger share of cost than in an apartment building or office tower, and most of that is 15-year land improvement property. Retail interiors are built for a specific business, so storefront treatments, millwork, specialty lighting and dedicated electrical often qualify as personal property. And retail turns over tenants, and each new tenant brings build-out costs that may be eligible for faster recovery.
39-year property. The structural shell, roof structure, foundation, load-bearing walls, standard building systems that serve the structure as a whole, and common finishes. A study does not make this bucket disappear. In most retail studies it remains the largest category.
5-year and 7-year property. Tangible personal property: decorative lighting, trade fixtures, specialty millwork, removable flooring tied to the retail business, dedicated electrical for equipment and signage, security and data cabling, and plumbing that serves specific equipment. Retail trade assets are often analyzed under Asset Guideline Class 57.0, a 5-year class. The line between personal property and structural components is drawn under the six-factor test from Whiteco Industries v. Commissioner, unpacked in our post on the Whiteco six-factor test.
15-year property. Land improvements under Asset Guideline Class 00.3: paving, parking lots, curbs, sidewalks, fencing, outdoor lighting, landscaping and irrigation, freestanding retaining walls and site drainage. Qualified improvement property, discussed below, is a separate 15-year category.
Land. Never depreciable. Retail parcels often carry a high land allocation; see our guide to land value allocation.
Property with a recovery period of 20 years or less is eligible for bonus depreciation, which covers everything a study moves into the 5-, 7- and 15-year classes. Bonus had been phasing down, to 80 percent for 2023, 60 percent for 2024 and 40 percent for 2025. The One Big Beautiful Bill Act, signed July 4, 2025, restored 100 percent bonus permanently for qualifying property acquired and placed in service after January 19, 2025.
The acquisition date controls, and a binding contract signed before January 20, 2025 that closed afterward stays at the prior rate. Our post on IRS Notice 2026-11 and your acquisition date explains the guidance, and the post on 100 percent bonus depreciation under the OBBBA gives the broader picture. Bonus is automatic; you can elect out by class of property if a slower schedule suits your situation, which is a decision to make with your CPA before filing.
The numbers below are illustrative, at a 37 percent federal rate. Actual reclassification varies with the property, the cost data and the site work.
Reggie is a dentist in Odessa, Texas, who buys a 14,000-square-foot neighborhood strip center for $4,000,000 in April 2025, fully leased and in service the day he closes. The appraisal puts 20 percent of the value on land, so his depreciable basis is $3,200,000. Without a study, he depreciates that over 39 years: $58,208 in 2025 at the April mid-month table rate of 1.819 percent, then about $82,000 a year.
An engineered study reviews the plans and cost data and finds about $330,000 of 5- and 7-year personal property (specialty lighting, millwork, dedicated electrical, signage-related items) and about $470,000 of 15-year land improvements (the parking field, curbing, sidewalks, site lighting, drainage and landscaping). The remaining $2,400,000 stays in 39-year property. The reclassified total is $800,000, or 25 percent of building basis.
With 100 percent bonus, Reggie has an $800,000 deduction on the reclassified property in year one, with no proration, plus $43,656 on the remaining $2,400,000 at the April rate, for $843,656 in all. That is $785,448 more than the $58,208 no-study baseline. At 37 percent, the extra deduction is worth about $290,600 if the loss can be used currently, which is the logic behind our post on when a study pays for itself.
Reggie has a problem many professionals share. His income comes from his practice, and he is not a real estate professional. The strip center is passive, so the loss cannot offset his dental income; it offsets other passive income, and the rest carries forward suspended. He and his wife file jointly, and the Section 461(l) cap of $626,000 for 2025 joint filers ($313,000 single, adjusted annually) would let most of the loss through if it were nonpassive, but the passive rules stop it first.
Lorraine buys a single-tenant pharmacy under a 15-year triple-net lease for $6,500,000 in June 2025, tenant in place. Land is allocated at 35 percent because the corner is valuable, leaving a $4,225,000 depreciable basis.
Net lease buildings often reclassify a smaller share because the interior is simpler and the tenant owns its fixtures, but the site work is substantial: a drive-through lane with canopy, a large parking field, lighting, signage and landscaping. Suppose the study reclassifies 20 percent of basis, $845,000, mostly 15-year land improvements with a smaller amount of 5-year property. With 100 percent bonus, that is an $845,000 first-year deduction, and the $3,380,000 that stays on 39 years takes $47,016 at the June table rate of 1.391 percent, for $892,016 in all. Without the study, the first year would have been $58,770.
Lorraine is a real estate professional who materially participates, with the aggregation election in place, so the loss is nonpassive. She and her husband file jointly. The pharmacy's net rent of about $400,000 turns into a net loss of about $492,000 after the study, under the $626,000 Section 461(l) cap for 2025 joint filers, so all of it is usable that year; at 37 percent, the extra $833,246 of depreciation is worth about $308,300. She also has to read the lease. If the tenant built and paid for certain improvements, Lorraine has no depreciable basis in them.
Darnell is a developer who builds a 9,000-square-foot retail building on a pad site for $3,100,000, including $600,000 of land, so his depreciable basis is $2,500,000. Significant physical work began in March 2025, which sets the acquisition date for self-constructed property, and the building was ready for its tenant in September 2025. Because Darnell built it, he has pay applications, schedules of values and invoices, and a study built on actual cost records is the approach the IRS guide calls the most methodical and accurate; see our post on ground-up development and construction cost records.
Darnell's study reclassifies $740,000, about 30 percent of basis, because a new pad site includes extensive paving, utilities, site lighting, signage and a specialized storefront and interior package. All of it takes 100 percent bonus. The $1,760,000 that stays on 39 years takes $13,182 at the September table rate of 0.749 percent, so first-year depreciation is $753,182 against $18,725 without a study, a difference of $734,457. Darnell and his wife file jointly; he is a real estate professional through the development business and materially participates in the rental, and his development company's income absorbs the loss, so the Section 461(l) cap does not come into play; at 37 percent the extra deduction is worth about $271,700.
Retail buildings change tenants constantly, and each change brings build-out costs. Qualified improvement property is an improvement made by the taxpayer to the interior of a nonresidential building after the building was first placed in service, excluding enlargements, elevators and escalators, and the internal structural framework. QIP has a 15-year recovery period and is eligible for bonus. Two details matter. The improvement must be made by the taxpayer, so a finished interior you bought from the prior owner is not QIP in your hands; the study examines that interior for components that qualify on other grounds. And when you as landlord fund a tenant improvement allowance, the landlord-funded interior work may qualify as QIP. Our post on tenant improvements and cost segregation covers who depreciates what.
When a tenant leaves and improvements are torn out, a partial asset disposition election lets you write off the remaining basis of the removed property. We cover the mechanics in our partial asset disposition guide.
Separate from bonus, Section 179(e) allows an immediate expense election for roofs, HVAC, fire protection and alarm systems, and security systems installed after the building was first placed in service. The limit is $2.5 million for 2025, indexed afterward. Section 179 has a taxable income limitation bonus does not, so have your CPA run both paths where they overlap.
Rental real estate is passive regardless of how much time you spend on it, unless you qualify as a real estate professional. Passive losses offset only passive income. With no passive income, the loss is suspended and carried forward, released against future passive income or when you dispose of your entire interest in a fully taxable transaction.
The $25,000 allowance for landlords who actively participate phases out between $100,000 and $150,000 of modified adjusted gross income, so most retail investors get little from it.
The real estate professional route, covered in our post on real estate professional status and cost segregation, changes the picture. The individual must perform more than 750 hours in real property trades or businesses during the year, more than half of all personal services performed, and then must materially participate in the rental activity itself, or in a group of activities under an aggregation election. We explain the tests in our material participation guide and the election in our grouping election guide.
Retail adds a wrinkle. Many investors hold net leased property because they want hands-off ownership, and that makes material participation hard to show. An owner who handles leasing, tenant relations and construction oversight on a multi-tenant center has a stronger case than the owner of a bank branch on a 20-year net lease.
Even for real estate professionals, the excess business loss limitation caps the net business loss usable against non-business income in a year; our post on the 2026 excess business loss limit walks through the numbers. If the property is owned through a partnership or S corporation, basis and at-risk limits apply at the owner level as well; see entity structure and deduction usability and syndications and K-1 losses. Know which situation you are in before you commission a study.
When you sell, depreciation claimed on 5- and 7-year personal property is recaptured as ordinary income under Section 1245, up to the amount taken. Land improvements and the building are Section 1250 property: straight-line depreciation comes back as unrecaptured Section 1250 gain at a maximum 25 percent federal rate, and any depreciation above straight-line is ordinary recapture.
A dollar deducted today is worth more than a dollar of tax owed years from now, and many investors never trigger recapture because they exchange under Section 1031, hold for decades, or pass the property to heirs at a stepped-up basis. We examine this in what happens when you sell, the 1031 exchange post, and the guide to inherited property and stepped-up basis. Model the exit before you commit.
If you acquired or built a retail property in a prior year, you can perform a study now and take the catch-up in the current year through Form 3115, as a Section 481(a) adjustment, with no amended returns. Cost Seg America prepares the Section 481(a) computation and, for a separate fee, the Form 3115 itself; your CPA files it. See look-back studies and missed depreciation, Form 3115, and the Section 481(a) adjustment.
The bonus rate on a look-back is set by when the property was placed in service, never by when you do the study.
The IRS Cost Segregation Audit Techniques Guide describes six common approaches. A fully engineered and accounted study works under the first two: detailed engineering from actual cost records, or engineering with documented estimates reconciled to actual cost. On a shopping center that means the electrical distribution, the decorative fixtures, the site utilities and the freestanding signs are each identified from the plans and from a proper inspection by an in-house analyst on larger properties, or a live video walkthrough, or a guided photo and video checklist the team reviews frame by frame. Each item is costed from contractor records where they exist and documented estimates where they do not, tied to a recovery period, a stated rationale and the authority behind it, with the lease read so landlord-owned and tenant-owned improvements are separated. The result is a component schedule your CPA imports and an examiner can trace line by line, signed by credentialed professionals, and defended for as long as you own the building. The estimated study hands your CPA a percentage, and a percentage cannot tell an examiner which improvements the tenant paid for.
This is the Reggie problem. A paper loss from a strip center does not touch wages or practice income unless the owner is a real estate professional who materially participates. Model usability before you commit.
In a net lease, tenants often build and pay for their own improvements, and the lease determines ownership. A study that classifies tenant-paid improvements as landlord property overstates basis and creates exposure.
Use a documented method, an appraisal, a county assessor ratio or a land-sales comparison, and stay consistent with your closing documents.
A retail building is placed in service when it is ready and available for its specific use, which is not always the closing date; finishing out a vacant shell shifts it. We explain the concept in what "placed in service" actually means.
Parking lot resurfacing, roof repairs and storefront refreshes may be deductible repairs or capitalized improvements under the tangible property regulations. Our post on repairs versus improvements goes through the framework.
If the depreciable basis after land is under $180,000, the fee eats the benefit. If you plan to sell within a couple of years with no exchange, recapture can outweigh the time value of the deduction. If you are a passive owner with no passive income and no path to nonpassive treatment, the loss sits suspended and the cash benefit arrives late; across a portfolio, the order you run studies in matters, as our post on portfolio timing strategy shows. We discuss these situations candidly in when not to do cost segregation.
Multi-tenant strip and neighborhood centers carry large parking fields and frequent turnover, so expect significant 15-year site work and a steady stream of QIP and partial disposition opportunities. Single-tenant net lease buildings (pharmacies, banks, auto parts, dollar stores, quick-service restaurants) carry meaningful site work and a smaller interior, and the lease decides what is yours. Restaurants push higher because kitchen plumbing, ventilation and electrical are examined closely. A mixed-use building with ground-floor retail sits on one schedule, 27.5 or 39 years, decided by the 80 percent gross rental income test; it is never split. Big-box and anchored centers can produce large dollar reclassifications even at a moderate percentage.
Yes. Retail properties often contain substantial land improvements, signage, specialty electrical and lighting, trade fixtures and tenant build-out items that can be examined as 5-year, 7-year or 15-year property. The share varies by property, and an engineered study is the way to measure it.
Yes, as long as you own depreciable basis. The study has to separate what the landlord owns from what the tenant owns under the lease. You cannot depreciate improvements you did not pay for.
Most retail lands within the 20 to 35 percent of depreciable basis range, which is $200,000 to $450,000 per $1 million of depreciable basis. Large paved sites and specialized interiors push toward the top; simple single-tenant boxes sit lower.
Only if you can use the loss under the passive activity rules, basis and at-risk limits, and the excess business loss limitation. Real estate professionals who materially participate generally can, subject to those limits. Other investors carry the loss forward.
Yes. A look-back study with Form 3115 takes the missed depreciation as a Section 481(a) adjustment on the current return, at the bonus rate that applied when the property was placed in service, with no amended returns.
The IRS has described the methodology in its own audit guide. The risk comes from poor studies, rule-of-thumb percentages and unsupported classifications. A documented engineered study that follows the guide's quality elements is the best protection, and nobody can promise what an examiner will pick.
