When this guide is useful
This fictional case concerns a projected deduction that may not currently reduce other income.
The distinction that matters
The example distinguishes the existence of a depreciation deduction from whether a taxpayer can use the resulting loss. Separate limitation analyses can apply.
A worked situation to investigate
A fictional owner receives a cost segregation estimate before supplying basis, financing and activity participation records.
The example is illustrative. Begin with the underlying event and its source documents, then separate missing facts from disagreements about their treatment. Work through the checks below in the order that matches your file, rather than treating a completed checklist as a tax conclusion.
Build a traceable handoff
Identify the affected person, entity or property and the relevant period. Keep original evidence, corrections and the reviewer's written conclusion connected. If the facts change after review, preserve the earlier version and ask whether the change affects implementation.
