What this file should establish
Describe what happens without the proposed action, including costs and timing. Compare the same facts and period for both options. A proposed deduction does not by itself identify incremental financial benefit.
An illustrative business owner is considering a change in tax classification while the operating model is changing.
A situation to work through
The business has stable sales but the owner has not documented duties or recurring administration costs.
For this situation, start with ownership records. Identify the period and legal owner before combining it with the other records. Keep the original source and explain any adjustments in a separate reconciliation.
Review point
A modeled advantage is a starting question, not evidence that the election is appropriate.
The headline compares a full proposed benefit with no baseline.
Question for the reviewer
What is the supported alternative and which assumptions differ?
Expected handoff
A like-for-like alternative comparison.
Separate facts supported by documents from estimates and unresolved assumptions. Assign each missing item to a responsible person and a date. Send the reconciliation alongside the source references so the reviewer can trace each conclusion.
