When this guide is useful
The company repays money described as an owner loan after several years of losses.

Identify the actual debt and any prior basis reductions. A payment described as principal may require analysis beyond a bank transfer memo.
A worked situation to investigate
An owner advances operating cash, uses debt basis in earlier years and later receives a partial repayment.
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.
