Which of the following is considered a red flag for identity theft under the FACT Act?

The identification of red flags for identity theft is critical for compliance with the Fair and Accurate Credit Transactions Act (FACT Act). One of the most significant indicators is when income documents appear significantly altered. This alteration can suggest that someone may be using someone else's information or that the documents are fraudulent. When income documents are not authentic or have been modified, it raises the suspicion that the individual associated with those documents may not be the actual person entitled to the tax return or refund, pointing to a higher risk of identity theft.

In contrast, confusion on the part of the taxpayer may not necessarily indicate identity theft but could simply reflect a lack of understanding regarding the process or documentation required. Having an identification document that is consistent with the person presenting it is typically a positive sign indicating validity and authenticity. Similarly, the timing of a refund request, including whether it is made "too early," does not inherently signal identity theft, as there may be legitimate reasons for a taxpayer to request a refund more quickly than usual. Therefore, the identification of altered income documents directly ties into detecting potential identity theft, making it the most relevant red flag in the context of this question.
