When this guide is useful
A buyer expects ongoing support for notices after a return is filed.
The distinction that matters
Distinguish explanation of a notice, payment-credit reconciliation and formal representation. Confirm which return periods and types of notices are included.
A worked situation to investigate
A client receives an agency notice and discovers that their annual package covers only the originally prepared return.
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.
