What this site is
austinairbnbtax.com is a free calculator for Austin short-term rental owners — answer five questions, get a specific year-one federal tax savings range under cost segregation plus the STR loophole. The math behind the calculator is the same engine used in Cost Seg Smart's paid IRS-defensible reports.
Who operates it
Cost Seg Smart LLC operates this site along with costsegsmart.com (the flagship paid product) and a network of related cost-segregation research sites. We are not affiliated with the IRS or any government agency. Recommendations to "order a study" route to costsegsmart.com — we disclose this upfront.
How content is reviewed
Every page across the network goes through a five-stage review:
- Source verification — claims cross-checked against IRS Pub 946, Treasury Reg §1.168, Treas. Reg. §1.469-1T (the STR loophole regulation), Rev. Proc. 87-56, and the IRS Cost Segregation Audit Techniques Guide.
- Methodology check — engineering claims reviewed against ASCSP cost-segregation methodology.
- Engine calibration — example numbers run through our engine, validated against a 260-property golden batch.
- QC validation — 16-check QC validator flags outside-band results.
- Compliance review — disclosure language and "tax advice vs. educational" boundaries.
What we don't claim
We don't list individual reviewers because the work is split across automated calibration, methodology check, and compliance sign-off. We don't claim every page is reviewed by a CPA or ASCSP-credentialed engineer. We claim our content is reviewed against IRS Pub 946, Treasury Reg §1.168, and ASCSP standards, and our engine implements those standards.
Calculator outputs are conservative ranges modeled from comparable engagements; your actual study will differ. This site is informational. Whether to apply a strategy to your situation is a question for your CPA.
