Cost segregation studies: Incomplete source records

Determine what cleanup or reconstruction sits outside the quoted work. Compare the property facts, methodology, report detail and return-preparer coordination.

Published by AE Tax Advisors. This is an AE-owned proposal comparison resource, not an independent rating or customer review.

What this file should establish

Identify missing books, schedules, invoices and ownership records. Ask who reconstructs the file, what alternatives are acceptable and how uncertainty is documented. A fixed fee does not guarantee that incomplete inputs support a conclusion.

Compare the property facts, methodology, report detail and return-preparer coordination.

A situation to work through

Two providers quote different cost pools for the same property.

For this situation, start with property basis. 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

Standardize the facts and distinguish the report from implementation.

The provider quotes from preliminary figures without defining missing-record work.

Question for the reviewer

Which missing records change the scope, cost or ability to complete the analysis?

Expected handoff

A source-gap and reconstruction scope file.

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.

Source and review boundaries

Use the following primary guidance to frame the questions. The worksheet organizes facts; it does not replace analysis of the relevant year, ownership, elections or state treatment. Record the applicable period, confirm the source version and retain the preparer's written conclusions with the supporting documents.
