The Basics
What Cost Segregation Does for Houston Property Owners
A cost segregation study identifies building components — HVAC systems, specialty flooring, parking surfaces, interior finishes, exterior lighting — that qualify for accelerated depreciation on 5-, 7-, or 15-year schedules rather than the default 27.5-year (residential rental) or 39-year (commercial) building schedule. Front-loading those deductions increases first-year cash flow and lowers current-year federal taxable income.
In Houston, that effect is straightforward at the state income-tax level: Texas has no state individual or corporate income tax, so the federal 100% bonus depreciation restored by the One Big Beautiful Bill (OBBBA, P.L. 119-21) — for qualified property placed in service after January 19, 2025 — flows through to Houston property owners with zero state income-tax adjustment. Federal Year 1 economics drop straight to the taxpayer’s federal savings. At the Texas franchise (margin) tax level, a major change took effect with 2026 reports: Texas now allows businesses to elect full deduction of qualifying fixed assets acquired after January 19, 2025 — meaning cost segregation now delivers a state-level franchise tax benefit for the first time (previously Texas conformed to 2007 IRC for depreciation, disallowing federal bonus depreciation for franchise tax purposes). For Houston’s dense concentration of energy operators, TMC medical facilities, and Ship Channel petrochemical operations, this new franchise tax election is a meaningful state-level lever.
No State Income Tax + New 2026 Franchise Tax Bonus Depreciation Election
Houston’s Tax Landscape — Why Cost Segregation Delivers Full Federal Stacking Here
State Individual Income Tax
None. Texas is one of nine states with no personal income tax.
State Corporate Income Tax
None. Texas has no state corporate income tax on business net income.
Franchise (Margin) Tax
Texas imposes a franchise tax on entities with annualized total revenue above the no-tax-due threshold ($2,650,000 for 2026 report year). Rates: 0.75% standard, 0.375% for entities primarily engaged in retailing or wholesaling, and 0.331% EZ computation for qualifying entities. Franchise tax is calculated on taxable margin (the lowest of 70% of total revenue, revenue minus COGS, revenue minus compensation, or revenue minus $1M).
NEW for 2026 Franchise Tax Reports
Texas allows businesses to elect full deduction of qualifying fixed assets (machinery, equipment, furnishings) acquired after January 19, 2025 — meaning cost segregation now delivers state franchise tax benefit for the first time. This is a significant break from Texas’s historical 2007 IRC conformity for depreciation.
Bonus Depreciation Conformity (Income Tax)
Not applicable at income-tax level — Texas has no state income tax that would require a bonus depreciation adjustment.
§179 Expensing
Federal §179 (2026 cap $2.56M, indexed from OBBBA’s $2.5M) applies at the federal level; state-level treatment now available through the 2026 franchise tax election.
Property Tax — Harris County Has the Country’s Most Layered Structure
~1.60% effective statewide (Tax Foundation); Harris County combined rate typically 2.0–2.5% depending on jurisdiction. But Houston’s property tax layering is uniquely complex: in addition to Harris County, City of Houston (or applicable municipality), and school district, most Houston-area properties fall within a Municipal Utility District (MUD) that adds a separate levy, plus the Harris County Flood Control District, Harris Health System (hospital district), and Port of Houston Authority. HCAD (Harris Central Appraisal District) manages roughly 1.9 million property accounts — the largest appraisal district in Texas, covering Houston, Pasadena, Baytown, and hundreds of smaller municipalities. Fort Bend, Montgomery, and other surrounding-metro counties share similar MUD structures. A separate lever from income tax — but a major cost driver for Houston commercial property.
Business Personal Property Rendition
Reported to HCAD by April 15 (automatic extension to May 15 on written request).
Sales Tax
State 6.25% + local up to 2% = combined 8.25% in Houston.
§481(a) Catch-Up
For Houston properties owned more than a year without a study, an automatic accounting-method change (Form 3115 under Rev. Proc. 2015-13 and its updates) captures all missed depreciation into the current tax year at the federal level — no amended returns required.

Real Numbers
What First-Year Savings Might Look Like in Houston
Results depend on property type, cost basis, construction year, and applicable depreciation rates — and we run a free benefit analysis before you commit to a study so you can see projected numbers first.
As a reference point, an Ambrose Group engagement on a $2.9M commercial property delivered $657,692 in first-year depreciation increase and $230,192 in first-year tax savings. In Houston specifically, all federal Year 1 savings apply directly — Texas has no state income tax adjustment. The new 2026 Texas franchise tax bonus depreciation election adds a state-level benefit for entities above the $2.65M franchise tax threshold that use the COGS or margin-minus-$1M computation methods — particularly relevant for Houston’s dense concentration of energy majors, Ship Channel petrochemical operators, and TMC medical operators.

Cost Segregation in Houston — Common Questions
Frequently Asked Questions
You’re headquartered in Jersey Village — does that mean better service for Houston properties?
Yes — practically speaking. Cost segregation methodology is federal, so the technical work is identical whether the provider is in Houston or across the country. But being headquartered in Jersey Village (Greater Houston) means our engineer conducts in-person Houston-metro site visits without travel cost or scheduling delay. It also means 30+ years of accumulated familiarity with Houston property types — TMC medical, Ship Channel petrochemical, Energy Corridor office, Uptown Class A, downtown corporate, plus the specific multifamily and industrial submarkets of the Inner Loop, Galleria, Cypress, Katy, and Sugar Land.
How does cost segregation work for Houston energy industry properties (upstream, midstream, downstream)?
Every segment of the energy value chain has distinct property profiles. Upstream E&P (exploration and production) facilities involve specialty industrial equipment, well site infrastructure, and processing facilities. Midstream (pipeline gathering, compression, storage) involves specialty piping, compressor stations, and tank farms. Downstream refining and petrochemical (Ship Channel corridor — LyondellBasell, Dow, INEOS, ExxonMobil Baytown, Shell Deer Park, Phillips 66) is among the country’s most equipment-intensive property types. Our engineer scopes each segment individually — the reclassification profile of an upstream well-site facility is very different from a midstream compressor station or a downstream refinery.
Is Texas Medical Center property particularly valuable for cost segregation?
Yes — very. TMC medical facilities are among the highest-reclassification-content property types in commercial real estate. Imaging suites (MRI, CT, PET), specialty surgical infrastructure, lab and research space, HVAC filtration for infection control, back-up power systems, medical gas infrastructure, and specialty mechanical systems all qualify for accelerated depreciation. TMC studies routinely reclassify 35-50% or more of building basis to shorter-life categories, well above the 22-35% typical range for standard commercial property.
Do you serve the entire Houston metro or just Harris County?
The entire Houston metro. Houston is a 9-county metro spanning Harris, Fort Bend, Montgomery, Brazoria, Galveston, Chambers, Liberty, Waller, and Austin counties — one of the largest metros by county count in the country. HCAD serves Harris County; Fort Bend (FBCAD), Montgomery, Brazoria, and Galveston have their own appraisal districts. Cost segregation is federal, so methodology is identical across counties. Metro operators with facilities across multiple Houston-metro counties (common for energy operators with Katy/Cypress office plus Ship Channel/Deer Park industrial) get single-engagement portfolio treatment.
How does Harris County’s uniquely layered property tax structure affect cost seg planning?
Harris County has the most layered property tax structure in Texas. In addition to county, city, and school district levies, most Harris County properties fall within a Municipal Utility District (MUD) with separate infrastructure taxes, plus the Harris County Flood Control District, Harris Health System (hospital district), and Port of Houston Authority. Combined rates typically run 2.0-2.5%. Cost segregation reduces federal income tax through accelerated depreciation — property tax planning (protest, ARB, arbitration) is a separate lever. Both operate independently but both matter for Houston commercial owners.
How does hurricane-damage rebuild interact with cost segregation and insurable value planning?
Houston is the only major U.S. metro with regular major-hurricane risk (Harvey 2017, Ike 2008, plus multiple named storm impacts). Hurricane-damage rebuild creates a specific cost seg opportunity: newly constructed replacement improvements are placed in service at the rebuild date, and cost seg on the rebuild captures maximum accelerated depreciation on the new components. Coordination with an insurable value appraisal is important — the same engineering-based analysis that supports cost seg also supports appropriate insurable value for the rebuilt property. Post-Harvey rebuilds specifically remain within the §481(a) look-back window for property owners who didn’t do cost seg at the time.
How does refinery and petrochemical plant turnaround timing affect cost segregation?
Ship Channel refineries and petrochemical plants (LyondellBasell, Dow, INEOS, ExxonMobil Baytown, Shell Deer Park, Phillips 66) periodically undergo “turnaround” — major planned maintenance shutdowns that often include significant capital improvements (new catalyst units, replacement heat exchangers, new specialty piping, control system upgrades). Turnaround-related capital work is generally placed in service at the completion of the turnaround, making it eligible for cost segregation. Refinery/petrochemical plant cost seg is a specialty niche — the equipment involved (§1245 process equipment, specialty piping, control systems) has distinct depreciation classification that requires engineering expertise.
Does cost segregation apply to Houston-based offshore oil and gas services operators?
Yes for the operators’ Houston-based facilities. Offshore services companies (Halliburton, Baker Hughes, Schlumberger/SLB, Weatherford, plus specialty operators) headquartered or with major operations in Houston depreciate their onshore facilities normally. This includes Houston-based specialty engineering offices, R&D labs, testing facilities, warehousing for offshore equipment, and specialty machining/repair shops. Offshore-deployed equipment itself (rigs, subsea equipment) has its own specialty depreciation treatment separate from the Houston real estate.
What about NASA Johnson Space Center-adjacent aerospace property in the Clear Lake / Nassau Bay corridor?
NASA Johnson Space Center itself is government-owned and doesn’t depreciate — but the extensive private aerospace ecosystem around it does. Boeing, Lockheed Martin, and specialty aerospace contractors operate private facilities in the Clear Lake / Nassau Bay / League City corridor with specialty content — clean rooms, specialty test facilities, aerospace-grade specialty electrical and HVAC infrastructure, and unusual security-required construction. These are strong cost seg candidates with atypical reclassification profiles.
What about The Woodlands and Spring master-planned Class A commercial (ExxonMobil Spring campus, HP Inc. Houston)?
Master-planned corporate campuses in The Woodlands and Spring — the ExxonMobil Spring campus (one of the largest single corporate campuses in the world), HP Inc. Houston operations, plus other master-planned corporate developments — have unusual reclassification profiles compared to urban Class A office. Master-planned campuses typically involve extensive land improvements (landscaping, entry drives, parking structures, plaza work), specialty central-plant infrastructure serving multiple buildings, campus-wide fiber and utility infrastructure, and executive amenity spaces. The specialty land improvement content is particularly reclassifiable to 15-year categories.
