A caller who has already been notified of an IRS data breach via Letter 4281C may indicate he or she is already a victim of identity theft as a result of the IRS data breach and would like the IRS to assist him or her in dealing with the identity theft.

AM CSRs will:

Apologize to the caller for any inconvenience.

Research the taxpayer's TIN thoroughly to see if there is a tax related issue related to the ID theft as defined in IRM 25.23.2.3.5, Identity Theft Research.

If a tax related issue is involved, see IRM 25.23.12.4, Tax-Related Identity Theft.

Input an Identity Theft Tracking Indicator as directed in IRM 25.23.2.4.4, Initial Allegation or Suspicion of Tax-Related identity Theft - IMF Identity Theft Indicators.

If the taxpayer is threatening litigation or legal action because the IRS data breach resulted in identity theft, in addition to the above actions, prepare a Form 4442, Inquiry Referral, to alert the IM Office of the possible litigation or legal action. See the referral procedures in IRM 10.5.4.4.7.6, Referrals to PGLD’s Incident Management Office.
