IRS ATG Compliance
IRS Publication 5653 (Cost Segregation Audit Techniques Guide) establishes the quality elements every defensible study must contain. Every CaliberSeg report is engineered to meet all 13.
Study prepared by a Specialized Tax Engineer with construction-engineering or cost-estimation credentials.
Documented scope of work, purpose, and the engineering methodology applied.
High-resolution photographic documentation of interior and exterior components, keyed to every classification.
Costs verified against closing statement, invoices, and our 197-line-item cost reference database.
Every dollar of depreciable basis reconciled to the original purchase price — to the penny.
Components grouped by MACRS recovery period (5, 7, 15, 27.5, 39-year) with authority citation for each.
Every classification carries its Rev. Proc. 87-56 asset class, ATG section reference, or Tax Court precedent.
Where new construction, RSMeans-grade engineering estimates applied — never free-form guesses.
Proper allocation between land (non-depreciable), §1245 personal property, and §1250 realty.
Soft costs, fees, and indirects allocated across asset classes in proportion to direct cost.
Parking, landscaping, fencing, signage, and utilities correctly identified as 15-year §1250 land improvements.
Whiteco six-factor test applied to every contested component — personal property vs. structural realty.
Complete asset schedule, depreciation projection, evidence chain, and Specialized Tax Engineer certification — ready for your CPA.
Every study is Signed & Certified by a Specialized Tax Engineer — your Audit-Defense Lead of record. Their credentials and signature appear on every page of the final report.
