How does third-party data verification support risk assessment?

• A. It replaces all self-reported information
• B. It provides independent income/withholding data to validate taxpayer information and identify discrepancies
• C. It is only used for large corporations
• D. It is optional and rarely used

Answer: (B)

Third-party data verification strengthens risk assessment by bringing in independent income and withholding information from employers, banks, and other payers. This external data is used to validate what taxpayers report on returns and to spot discrepancies between self-reported figures and the data those payers already have on file. When mismatches appear, the risk assessment can flag higher risk and trigger targeted reviews, helping ensure accuracy and focus enforcement where noncompliance is more likely. This verification complements self-reported information rather than replacing it, and it is widely used across taxpayers to improve the quality of risk scoring.
