Financial Analysis and Forensic Accounting
Financial Analysis and Forensic Accounting
This domain tests the indirect methods used to prove income when records are unreliable, and the forensic discipline needed to get that reconstruction into evidence and make it intelligible to a jury.
Indirect methods
- Net worth: increase in net worth + personal expenditures − nontaxable receipts = taxable income. The opening net worth must be established with precision, and the agent must show a likely source of income and negate nontaxable sources (Holland v. United States).
- Expenditures method: apply nontaxable funds first, then treat the excess of expenditures over reported income as unreported receipts.
- Bank deposits / cash T-account: total deposits − nontaxable items − transfers = gross receipts.
- Specific items: prove discrete understatements when records are adequate.
Forensic presentation
- Maintain chain of custody for seized and produced records; authenticate under FRE 901 and use FRE 803(6) for business records.
- Summary exhibits under FRE 1006 must be supported by available underlying documents.
- Corroborate admissions and the reconstructed figures; uncorroborated net-worth assertions are insufficient (Smith v. United States).
Worked example
Bank-deposit reconstruction: total deposits $512,000. Documented exclusions are a $90,000 loan (note and repayments), $40,000 in gifts (donor statements, gift tax return), and $22,000 in transfers between the taxpayer's own accounts. Gross receipts = $512,000 − $90,000 − $40,000 − $22,000 = $360,000. Reported receipts were $300,000, so the understatement is $60,000. Reasoning: every exclusion must be independently documented; an undocumented exclusion moves the entire computation back toward the taxpayer's position at trial.
Traps that cost marks
- Failing to negate the cash-hoard or nontaxable-source defense at the opening net worth.
- Double counting transfers between accounts.
- Building a net worth computation on inconsistent asset valuations across years.
- Offering a summary exhibit without the underlying records or a sponsoring witness.
