The question this page answers
What does signing and filing steps establish in this file, and what additional fact could change the next step? A buyer asks for a lookback review covering several years and entities.
Distinguish the recommendation from completed implementation
Identify the approved decision, responsible professional and expected completion record. Keep draft work, approved work and filed or posted work separately. A conversation about a change is not evidence that the final system or return reflects it.
Apply the check to the situation
A planning proposal includes a prior-year review but the buyer assumes three amended returns are already included.
For this check, identify the document that supports signing and filing steps. Compare it with client document duties before treating the two records as consistent. A difference may indicate separate events, incomplete history or a correction that has not yet reached every system.
Compare sources before accepting the result
Compare the accepted instruction with the actual filing, schedule or posting. Record the version, reporting period and any unresolved dependency. Where another professional must act, obtain their acknowledgement of the assigned responsibility.
Handle an incomplete or conflicting file
If the implementation record differs from the accepted decision, ask the responsible professional to explain the difference before declaring completion. Keep any corrected version and the reason for correction with the source evidence.
| Evidence state | Action for this check |
|---|---|
| Supported and consistent | Record the source version and exactly what it establishes about signing and filing steps. Leave the tax conclusion to the responsible reviewer. |
| Missing | Request the underlying evidence and assign a follow-up owner. Identify whether the missing item prevents review or only delays implementation. |
| Conflicting | Keep both sources, describe the difference and request an explanation. Do not silently choose the source producing a preferred outcome. |
| Estimated | Explain the reconstruction method, uncertainty and reviewer approval required before using the estimate. |
| Proposed not applicable | Record why this question does not apply and obtain confirmation where the decision depends on that exclusion. |
The focused reviewer handoff
Submit the source reference, the finding about signing and filing steps, the unresolved difference and the requested decision. If the reviewer approves an action, ask what proves its completion. Continue with agency follow-up terms to check the connected part of the file.
