- The median Austin STR generates ~$43,000 in Year-1 federal tax savings on a $625K purchase price at the 37% bracket with 100% bonus depreciation under OBBBA (2025+). Engine-truth reclassification: 27% of depreciable basis into 5/7/15-year MACRS classes.
- Austin land allocation runs 18%–42% depending on neighborhood, per Travis County TCAD assessor records. Coastal-equivalent premium (Westlake / Tarrytown) hits 42%; inland Austin runs ~25%; condo-dense Downtown / Rainey runs ~26%.
- Austin produces above-national-average cost-seg ROI due to three structural factors: Texas has no state income tax (federal benefit is the whole benefit); event-driven STR market (SXSW, F1, ACL, UT) drives premium FF&E density; East Austin / Mueller / South Congress 2010–2019 builds are sweet-spot construction era for reclassification.
Cost segregation is a 25-year-old US tax strategy with most of its industry data locked behind paid reports or major-firm marketing claims. Austin's high-volume short-term rental market and large 2018–2024 build-out create a particularly clean dataset: a city with consistent property-type composition (event-driven STRs, Mueller / East Austin redevelopment, North Loop infill multifamily, Downtown condo) and well-documented Travis County assessor records.
This page publishes Austin-specific cost-segregation benchmarks as an open dataset. Numbers are engine-truth outputs from the Cost Seg Smart cost segregation engine, calibrated against RSMeans 2024 construction cost data, MACRS classification per Rev. Proc. 87-56, and the IRS Cost Segregation Audit Techniques Guide (Pub 5653). Land allocation reflects Travis County Appraisal District (TCAD) typical ratios. CC-BY 4.0; cite with attribution.
Austin cost segregation at a glance
Methodology & data sources
The numbers on this page are produced by the Cost Seg Smart cost segregation engine, applying RSMeans 2024 cost data + MACRS classification per Rev. Proc. 87-56 + the IRS ATG framework to representative Austin property profiles. The data sources, in priority order:
- RSMeans 2024 Building Construction Cost Data — primary $/SF cost basis for component classification, with regional cost multipliers calibrated to the Austin / Central Texas market.
- Travis County Appraisal District (TCAD) — assessor records for land allocation methodology, used as the primary source for land/improvement split where reliable.
- IRS Pub 946 (How To Depreciate Property) — depreciation rules, MACRS conventions, recovery-period tables.
- Rev. Proc. 87-56 — asset class lives. Authoritative source for which components classify as 5-, 7-, 15-, 27.5-, or 39-year property.
- IRS Pub 5653 (Cost Segregation ATG) — the 13-element quality framework that defines what a defensible cost-seg study contains.
- BLS Producer Price Index (Construction) — time-index cost adjustment so RSMeans 2024 baseline reflects the year-of-acquisition dollars.
- OpenStreetMap / Overpass API — cross-verification of building type, footprint, and land-use classification.
Per-property-type accelerated allocation percentages are calibrated against thousands of cost segregation studies across all major US property types. Austin-specific neighborhood land allocations are TCAD-typical and reflect 2024–2026 assessor records.
Reclassification percentage by Austin property type
The headline number for cost segregation is the accelerated reclassification percentage — what share of the depreciable basis (purchase price minus land value) gets moved from 27.5-year (residential) or 39-year (commercial) recovery periods into shorter 5-, 7-, or 15-year MACRS classes. Higher reclassification = larger Year-1 deduction.
| Property type | Median accel % | 5-year % | 15-year % | Notes |
|---|---|---|---|---|
| Short-term rental (STR / Airbnb) | 27.2% | ~19% | ~7% | Higher than national STR median (29.8%) tempered slightly by typical Austin land allocation |
| Single-family rental (LTR) | 18.7% | ~9% | ~9% | Standard suburban SFR profile |
| Condo (Downtown / Rainey) | 14.4% | ~13% | ~1% | Lower 15-year due to shared site improvements |
| Duplex / triplex / fourplex | 19.5–20.0% | ~12% | ~8% | Slightly above SFR due to per-unit FF&E + shared mechanical |
| Office (Downtown / Rainey, Mueller, North Burnet) | 27.0% | ~17% | ~10% | Commercial site work + 5-year fixtures drive higher accel |
| Retail / restaurant (East 6th, SoCo, Rainey) | 30.5% | ~22% | ~8% | Storefront fixtures + commercial finishes elevate 5-year share |

Land allocation by Austin neighborhood
Land is non-depreciable, so the share of purchase price allocated to land directly determines what's available to reclassify. Austin runs a wide range — coastal-equivalent premium markets like Westlake / Tarrytown push above 40%; inland workforce markets stay below 25%. These ratios are TCAD-typical based on 2024–2026 assessor records:
| Neighborhood / area | Typical land % | Notes |
|---|---|---|
| East Austin (78702) | 31% | Urban core, dense lots, redevelopment-heavy |
| South Congress (78704) | 36% | Premium walkable, event-adjacent |
| Zilker (78704) | 36% | Premium central, lake-adjacent |
| Mueller (78723) | 30% | Master-planned redevelopment, modern build |
| Westlake / Tarrytown (78703 / 78746) | 42% | Luxury, large lots, ultra-premium land |
| North Loop (78751) | 28% | Urban infill, mixed condition |
| Downtown / Rainey (78701) | 26% | Condo-heavy, smaller per-unit land share |
| Other Austin (general inland) | 25% | Suburban / workforce baseline |

Why Austin produces above-national-average cost-seg ROI
Three structural factors push Austin's cost-seg numbers above the national median:
- No Texas state income tax. Federal cost-seg savings are the entire Year-1 benefit. No decoupling math, no state addback, no parallel state depreciation schedule. Compared to California, where state-level §168(k) decoupling requires a parallel state schedule on the full straight-line basis, Texas is the cleanest STR cost-seg jurisdiction in the country.
- Event-driven STR market. SXSW (March), Formula 1 USGP (October), Austin City Limits (October), University of Texas football (fall). Premium FF&E loadouts compete on event-week pricing — themed bedrooms, bachelorette-friendly layouts, premium furnishings — all 5-year personal property under MACRS. Austin STR FF&E density typically runs $30,000–$60,000 per property.
- Sweet-spot construction era. East Austin redevelopment 2010–2019, Mueller master-planned community 2008–2022, South Congress / Zilker infill 2014–2024. Modern construction with HVAC, electrical, and finishes built to current code — these systems classify as 5/7-year property (vs. 27.5-year structural shell), driving accelerated reclassification above national STR median.
- Material-participation friendly. The §469 short-term-rental loophole (7-day average stay) fits Austin's event-heavy STR pattern naturally. Self-managing owners almost certainly clear the 100-hour material-participation bar, making losses non-passive without requiring Real Estate Professional Status.
Texas tax context
Texas has no state personal income tax. The federal Year-1 cost-seg deduction is the entire Year-1 tax benefit — there's no parallel state schedule to maintain. Property tax (Travis County / City of Austin) is among the highest in the US (effective 1.8%–2.2% of market value for residential), but that's a separate consideration from cost seg, which works off federal basis (acquisition cost minus land plus capital improvements). Property-tax level doesn't change federal depreciable basis.
Compared to California: Austin's no-state-tax structure is the cleanest cost-seg jurisdiction. Compared to Florida: similar (no state tax), but FL effective property tax is materially lower than Texas. Compared to Tennessee: similar in tax simplicity.

Frequently asked
What's the typical Year-1 federal tax savings on a $500K Austin short-term rental?
Approximately $36,500 at a 37% federal bracket with 100% bonus depreciation under OBBBA (2025+). The math: $500K × 75% (after typical 25% Austin land allocation) = $375K depreciable basis × 27% accelerated reclassification (STR median per the engine) = $101K reclassified into 5/7/15-year MACRS classes × 100% bonus × 37% bracket = $37,370. Rounding to median: ~$36,500. Actual results vary by neighborhood — East Austin and South Congress run higher accel ratios due to FF&E density, while inland markets run lower.
What's the average land allocation in Austin for cost segregation?
Land allocation in Austin runs 18% to 42% depending on neighborhood, per Travis County TCAD assessor records. East Austin: ~31%. South Congress / Zilker: ~36%. Mueller: ~30%. Westlake / Tarrytown: ~42% (luxury, large lots). North Loop: ~28%. Downtown / Rainey: ~26% (condo-heavy, smaller land share). Inland Austin median: ~25%. Land is non-depreciable, so higher land allocation produces a smaller depreciable basis but typically reflects premium $/SF construction quality on the structure side.
How much does a cost segregation study cost in Austin in 2026?
Austin cost segregation pricing tiers for residential property: $495 (under $300K basis), $795 ($300K–$700K), $895 ($700K–$1M), $1,295 ($1M–$2M), $1,595 ($2M–$5M), $1,895 ($5M–$15M). Multifamily 2–4 unit: $995–$1,995 depending on basis. Commercial: $995–$2,995. Most Austin residential rentals land in the $795 or $895 tier. Traditional engineering firms quote $5,000–$15,000 for the same property — the methodology (RSMeans 2024 + MACRS per Rev. Proc. 87-56 + IRS ATG framework) is identical; the labor model differs.
Why does Austin produce above-average cost-seg savings?
Three structural factors: (1) Texas has no state income tax, so federal cost-seg savings are the entire benefit — no state-level decoupling complexity; (2) Austin's event-driven STR market (SXSW, F1, ACL, UT football) drives premium FF&E density, pushing 5-year personal property reclassification above national STR averages; (3) East Austin / Mueller / South Congress builds 2010–2019 are sweet-spot construction era for cost-seg reclassification because modern systems (HVAC, electrical, finishes) classify as 5/7-year property rather than 27.5-year structural.
What's the typical accelerated reclassification % for Austin properties?
By property type: STR ~27% of depreciable basis; SFR ~19%; condo ~14%; duplex/triplex/fourplex ~20%; office ~27%; retail ~31%. STRs run materially higher than long-term rentals because furnished rentals carry significant 5-year personal property (furniture, fixtures, appliances) that LTRs don't. Austin's STR concentration in event-heavy neighborhoods (East Austin, Zilker, Westlake) typically produces the upper end of the STR range, in the 28–32% accelerated allocation territory.
Does Travis County reassessment affect cost segregation?
No. Travis County reassessments affect property tax (your TCAD bill), not the IRS basis for federal cost segregation. Your cost-seg basis is your acquisition cost from the closing disclosure plus subsequent capital improvements minus land value — not the assessor's market value. The assessor's land/improvement split is one input to the cost-seg study's land allocation methodology, but reassessments of total property value don't change federal depreciable basis once placed in service.
