The IRS Audit Technique Guide (ATG) defines a quality Cost Seg report by six primary hallmarks that ensure the study is credible, reliable, and able to withstand scrutiny, focusing heavily on the preparer's expertise, documentation, and methodology. A top-tier study not only accelerates your tax benefits but also stands up confidently under an IRS audit because it follows these comprehensive standards.
The key requirements include having qualified preparers (engineers, CPAs, or specialists with relevant expertise), clear and detailed methodology explaining the step-by-step classification, and comprehensive documentation (blueprints, construction documents) to create a transparent audit trail. Furthermore, the report must include citations to legal authority (IRS rulings, regulations), utilize consistent and logical allocation methods, and provide a reconciliation of costs to trace every dollar from the original basis to its final assigned category.
IRS Quality Hallmarks: The 6 ATG Requirements
- Qualified Preparers: The study must be prepared by knowledgeable professionals (engineers, CPAs, or specialists) demonstrating relevant expertise, credentials, and experience in construction, tax law, and depreciation rules.
- Clear & Detailed Methodology: The report must provide a step-by-step narrative explaining how each component was identified, classified (e.g., into 5, 7, or 15-year property), and valued.
- Comprehensive Documentation: Includes blueprints, construction documents, architectural plans, and other tangible evidence supporting the allocations to create a transparent audit trail.
- Citations to Legal Authority: The study must reference authoritative guidance such as IRS rulings, Treasury regulations, and court cases, providing a solid legal foundation for classifications.
- Consistent & Logical Allocation Methods: The report must show rational, justifiable techniques for assigning costs and demonstrate consistency across similar properties.
- Reconciliation of Costs: A quality study reconciles total project cost to the final allocations, ensuring every dollar is traceable and leaving no unexplained amounts or gaps.
