If you earn a W-2 in San Antonio, your combined marginal rate runs federal 37% + NIIT 3.8% = ~40.8% combined with Texas’s 0% state income tax. That’s a lower wedge than coastal high-bracket metros, but it’s stacked against the highest disposable-income velocity per dollar of W-2 in the Sunbelt, and San Antonio’s investor pool has unusually short driving access to premium Hill Country, Broken Bow, and Gulf Coast STR markets.
- $122,000 Accelerated Depreciation (typical STR worked example)
- $50,000 Est. Year-1 Tax Savings (federal + NIIT, no state)
- 63x Return on Study Cost

Who are San Antonio cost segregation investors?
San Antonio’s W-2 investor pool clusters around four archetypes distinct from Austin and Dallas:
- USAA Home Office: USAA’s campus in Northwest San Antonio employs ~19,000, one of the largest single-employer concentrations in the country. Senior product, engineering, claims, and investment leadership. Comp generally $250K–$700K + RSU equivalents.
- Valero + energy (Valero Energy HQ, NuStar Energy, Andeavor legacy): senior refining, finance, and trading leadership. $300K–$1M+.
- Joint Base San Antonio (military): JBSA-Randolph + JBSA-Lackland + JBSA-Fort Sam Houston (Brooke Army Medical Center). Senior officer corps (O-5+), BAMC attending physicians, military medical research leadership. Base pay plus medical specialty pay, BAH, and concurrent receipt for retired officers; many also hold concurrent civilian/contractor roles.
- HEB + senior corporate: HEB executive ranks (privately held; senior comp competitive with public-co peers), plus senior Whataburger HQ, plus Bill Miller’s Bar-B-Q ownership tier. $300K–$1.5M+.
The combined marginal-rate stack:
- Federal: 37% (top bracket)
- NIIT: 3.8%
- Texas state: 0%
- Combined: ~40.8%
The Texas wedge is lower than coastal high-bracket metros (NYC 51.5%, CA 50.3%, DC 51.5%), but San Antonio’s structural advantage is proximity-to-STR-market rather than wedge-amplification. The 100-hour material participation test under Reg. §1.469-1T(e)(3)(ii) is meaningfully easier to meet when the STR is a 2-hour drive away vs a flight.
Verify with your CPA. Combined-rate math depends on filing status, AGI thresholds for NIIT, and whether your deduction offsets active vs passive income.
Why cost seg pays for San Antonio investors
A typical $400K–$800K out-of-state STR reclassifies 24–32% of basis under permanent 100% bonus depreciation. At the San Antonio combined bracket (~40.8%), every $1 of accelerated depreciation is worth ~$0.408 in Year-1 cash savings.
The San Antonio-specific feature: monthly drive-to material participation. The STR exception under Reg. §1.469-1T(e)(3)(ii) requires 100+ hours of material participation per year. For NYC or Bay Area investors, that means flying to the property, manageable but expensive. For San Antonio investors, Fredericksburg (90 min), New Braunfels (45 min), Wimberley (90 min), and even Hochatown OK (4 hours) all support monthly weekend visits within the 100-hour threshold without flights. Active remote management plus 2–3 days/month on-site clears the test for most investors.

Where do San Antonio investors buy property?
San Antonio investors flow capital to STR markets within a 2–4 hour drive or short flight:
- Fredericksburg, TX (Hill Country wine-country STR): 90 min drive; $400K–$900K cottages, premium ADR during weekends.
- Broken Bow, OK — Hochatown: Beavers Bend log-cabin STR, 4-hour drive. TX-resident investors get the full 40.8% federal-only benefit since OK has no state-tax interaction for non-resident owners.
- Pigeon Forge / Gatlinburg, TN — Smokies: Tennessee 0% state tax, cabin STR, direct San Antonio→Knoxville flights.
- 30A / Destin, FL: Florida 0% state tax, premium beachfront, direct San Antonio→VPS flights.
- Joshua Tree, CA: Desert STR; CA-side property has 13.3% state-tax exposure for CA-resident owners, but TX-resident investors only owe federal.
Worked Example — San Antonio
A USAA senior product manager earning $385K base + $90K performance equity, residing in Stone Oak, buys a 3BR Fredericksburg cottage (Texas Hill Country wine-country STR market) for $525K with $20K immediate FF&E (hot tub, smart locks, theater seating). After $115K in land, the $410K adjusted basis includes $48K in 5-year assets (appliances, hot tub, smart-home, theater equipment, decorative lighting), $18K in 7-year assets (custom guest-room furnishings, ranch-decor built-ins), and $56K in 15-year property (limestone patio, fencing, drought-tolerant landscape, outdoor lighting).
That’s $122K reclassified into accelerated depreciation in Year 1. At the San Antonio combined bracket (~40.8%), federal + NIIT savings come to roughly $50,000, about 63x the cost of the study.
Who doesn’t qualify for cost segregation in San Antonio?
REPS (Real Estate Professional Status, 750+ hours + >50% personal services in real estate) is structurally impossible for a full-time USAA / Valero / HEB executive or a full-time active-duty officer. The STR exception under Reg. §1.469-1T(e)(3)(ii) (7-day average stay + 100+ hours material participation) is the path.
Military edge case: Retired O-5+ officers with concurrent receipt who run real estate full-time can credibly claim REPS in the retirement year. Active-duty officers with 14-hour days plus deployments cannot. Coordinate with a CPA familiar with the §469 regulations for military filers.
Frequently Asked Questions
How much does a cost segregation study cost in San Antonio? For a representative $525,000 San Antonio investment property, a Cost Seg Smart study runs $895. Full pricing: $495 (under $300K), $895 ($300K–$700K), $995 ($700K–$1M), $1,295 ($1M–$1.5M), $1,595 ($1.5M–$2M), $1,995 ($2M–$3M), $2,495 ($3M–$4M), $3,995 ($4M–$6M), $5,995 ($6M–$8M), $7,995 ($8M–$10M). Commercial and 5+ unit multifamily studies start at $1,995; 2–4 unit multifamily from $795. All studies delivered in under one hour with the CPA-Ready Guarantee: full refund if your CPA can’t use the report.
Does Texas conform to federal bonus depreciation? Texas has no state income tax, so the federal Year-1 bonus depreciation deduction (100% under OBBBA §168(k) for property placed in service after January 19, 2025) is the full benefit. No state-level conformity question: no Form TX-equivalent adjustment, no state recapture.
Can active-duty officers stationed at JBSA use cost segregation? Yes. Cost segregation is a federal income tax election; military pay is federally taxable income. The Reg. §1.469-1T(e)(3)(ii) STR material participation test is income-tax-based, not employment-based. The practical bottleneck is the 100-hour material participation requirement: deployment cycles and ops tempo can make this difficult to meet in a calendar year. Plan with a CPA familiar with military filers.
Why are USAA + Valero senior employees a good fit for cost seg? USAA and Valero senior employees generally have $300K–$1M comp + RSU/equivalent equity vesting, locking them into the top federal bracket. Texas’s 0% state tax means every reclassified dollar saves the full federal 40.8% with no state-level deferral or modification. Combined with strong Hill Country STR feeder markets (Fredericksburg, Wimberley, New Braunfels) within 90 minutes, San Antonio is one of the cleanest cost-seg setups in the Sunbelt.
What’s the difference between San Antonio and Austin for cost seg? Federal math is identical (TX 0% state). Differences: (1) San Antonio investors generally buy slightly cheaper STRs in Hill Country wine country or Hochatown ($350K–$700K) vs Austin investors who skew toward higher-priced Lake Travis / 30A / Aspen ($600K–$1.5M); (2) JBSA medical/officer profile is unique to San Antonio; (3) Austin’s tech-RSU profile pushes deeper into commercial cost-seg (office condo conversions, mixed-use), which San Antonio investors do less often.

Tax law current as of July 2026. Federal: OBBBA restored 100% bonus depreciation under §168(k), permanent for property both acquired and placed in service after January 19, 2025 (property acquired or placed in service on or before that date remains under the prior 40% phase-down); 2026+ stays 100%. State conformity varies; verify with your CPA.
CPA use note: These figures estimate the size of the depreciation deduction. Whether the loss is usable in the current year depends on passive-activity rules, STR material participation, REPS status, entity structure, depreciable basis, and state conformity. Your CPA decides how and when it is applied. Specialty and site components (equipment, casework, docks, pools, arenas, tenant improvements, and similar) are only classified when you own them and they are included in the depreciable basis being studied.
How should San Antonio, TX investors choose a cost segregation provider?
For a San Antonio, TX investor buying a property in the $525,000 range, the choice of provider is a major controllable variable in the return. The IRS Audit Techniques Guide sets the quality characteristics an engineering-based study should meet — industry-standard construction cost data, MACRS classification, and component-level documentation — but it does not make every provider's work identical; rigor, cost, and turnaround still vary.
Traditional engineering studies often run several thousand dollars and can take several weeks, because they include on-site inspections, sales discovery calls, and scheduling overhead. The IRS Cost Segregation Audit Techniques Guide does not prescribe an on-site inspection as a standalone requirement; it sets out the quality characteristics of an engineering-based study — component-level classification, a documented and supportable cost derivation, and a clear audit trail — and describes how a physical inspection can contribute to meeting them.
Modern automated providers (such as Cost Seg Smart) deliver an engineering-based, IRS ATG-aligned study using property records, documents, photos, and recognized construction-cost data, typically from $495 and often the same day. For a San Antonio, TX investor at a high combined bracket, that cost and speed difference is meaningful. The CPA-Ready Guarantee (full refund if the report can't be used by your CPA) plus the 60-day money-back policy makes the decision essentially risk-free on the report itself.
The automated path is best-fit for owners who can provide closing documents and property photos online (no in-person visit required) and want the report in time to file the current year's return rather than the next one.
All Cost Seg Smart studies include the CPA-Ready Guarantee (full refund if your CPA can't use the report) plus a 60-day money-back policy. Straightforward residential studies are often delivered the same day and completed remotely; larger or more complex commercial studies take longer and may include an on-site observation.
