The 5-Year Audit Defense Standard: How WeCostSeg Defends Every Study

Every WeCostSeg study includes five years of written audit defense covering methodology, asset classifications, and engineering conclusions, aligned to the thirteen Principal Elements of a Quality Cost Segregation Study in IRS Publication 5653.

The decision logic

Each report ships with all 13 Principal Elements addressed in writing. Each engagement carries five years of post-delivery defense without an additional fee.

How the framework breaks down

• Elements 1-4: Engineer qualifications, on-site inspection or virtual equivalent, written methodology, documented assumptions
• Elements 5-9: Asset classifications per Section 1245/1250, recovery period justification, allocation methods, cost detail
• Elements 10-13: Photo documentation, source documentation, computation accuracy, supporting case law citations

Worked examples

• Engineer CV included with every study.
• Photo log archived for every property.
• Form 3115 prep included when a Section 481(a) adjustment is required.
