Corporate & Accounting Fraud Scheme Taxonomy
A systematic, ledger-level breakdown of how financial statement manipulation occurs. Fraudulent schemes are categorized into five core families based on the primary accounts affected: Revenue Recognition, Expenses and Reserves, Balance Sheet and Assets, Disclosure and Controls, and Auditor Conduct.
TAXONOMY BENCHMARKS
- The Corporate Fraud Library catalogues 32 standardized accounting fraud schemes across 5 families.
- Revenue recognition abuses account for the majority of early-stage financial statement restatements.
- Balance sheet schemes (such as fake cash and off-balance-sheet entities) generate the largest cumulative shareholder losses.
- Every scheme is linked to historical enforcement cases and mathematical red-flag formulas.
