When this guide is useful
A proposal combines tax planning with discussion of retirement contributions.
The distinction that matters
Clarify the roles of the tax adviser, plan administrator and investment professional. A tax projection does not replace plan design or eligibility testing.
A worked situation to investigate
A business owner expects a large contribution while the administrator has not reviewed the employee census.
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.
