Recommendations

The Deputy Commissioner for Services and Enforcement should establish systemic controls in the RTS to revoke ITINs determined to be issued in error after the three-day quality review period (i.e., the system should not accept a reject action).

The Commissioner, Wage and Investment Division, should review the 95,928 ITINs TIGTA identified that were issued with a rejected application and take the actions necessary to revoke the ITINs if appropriate.

The Deputy Commissioner for Services and Enforcement should: Review the 44,532 ITINs we identified that were issued to individuals using the same **************2************* and the 10,924 ITINs we identified that were issued to individuals who used duplicate supporting documents to determine the validity of the ITINs and take the actions necessary to revoke those ITINs that are determined to be invalid.

The Commissioner, Wage and Investment Division, should review the 8,110 ITINs identified with a revoked status in the RTS but still valid on the IMF and take necessary action to change the ITINs to invalid.

The Commissioner, Wage and Investment Division, should review the 1,237 ITINs identified with a revoked status in the RTS but still active on the NAP and take necessary action to remove the ITIN from the NAP.
