Build two maps
One map should show legal ownership and control. Another should show the tax treatment of the entities and their relationships. The two may differ: a legally separate entity may be disregarded for particular federal tax purposes. That does not erase contracts, state-law obligations, or every tax responsibility. Label the purpose of each diagram so readers do not confuse them.
Obtain evidence for each classification
Collect formation and conversion documents, elections, acceptance notices, returns, ownership changes, and prior transaction files. An accountant’s shorthand description may be correct, but diligence should identify the supporting record. If the business lacks a document, list the gap and decide who will investigate it. Do not replace a missing election with a confident label in the chart.
Trace guarantees and intercompany balances
Ownership is only part of the economic story. A subsidiary may depend on a parent guarantee, shared employees, intellectual property, or an intercompany loan. Those arrangements can affect valuation and transaction planning. Reconcile balances to records and determine whether agreements reflect how the business actually operates.
Explain what a discrepancy changes
A useful diligence report connects the problem to a decision: revised price, delayed closing, specialist advice, additional representation, indemnity, or a corrective filing. Not every discrepancy is fatal. But unresolved uncertainty should be visible to the people negotiating the transaction. The report should not bury the only material risk in an appendix of routine certificates.
A practical comparison
| Issue | What to examine | Practical safeguard |
|---|---|---|
| Legal ownership | Formation and transfer records | Verify current interests |
| Tax treatment | Elections and returns | Identify supporting evidence |
| Economic dependency | Loans and guarantees | Assess obligations beyond shares |
| Remedy | Risk and proposed action | Assign an owner and deadline |

Resolve material gaps
An explanatory workflow, not a prediction of an individual result.
A worked example
Hypothetical: a valuation assumes an LLC is a partnership because it has two names on an internal chart. Records show a prior corporate classification election. The team must revisit the tax assumptions and determine which calculations change rather than merely relabel the illustration.
Questions to resolve before acting
Does an LLC label tell me its federal tax classification?
No. The IRS explains that treatment can depend on ownership and elections. Review the actual records.
Use the comparison above to identify the records and unanswered questions that will affect the next decision. Keep the original documents, note where each important fact came from, and distinguish an assumption from something independently verified. A short, accurate explanation of the problem is more useful than a large collection of unorganized material.
