The IRC controls the maintenance, use, and disclosure of tax return information. We
                  also must comply with the Privacy Act when maintaining, using, and disclosing tax
                  return information. We may use and disclose tax return information only as authorized
                  by the IRC, the Social Security Act, or the IRS.
               
               Sometimes we obtain wage and employment information from a source other than the wage
                  reporting process, i.e., other than a tax return or schedule filed with IRS or with
                  us. For example, a person may give the field office a copy of their W-2 or 1040 tax
                  return as proof of employment in a claims situation. Because the information was received
                  directly from the person, it is not considered tax return information subject to the
                  restrictions in the IRC (see second bullet GN 03320.001D.2).
               
               If we receive wage or employment information directly from a person and use the information
                  to create or amend the person’s official earnings record, the newly created or amended
                  earnings record is tax return information controlled by the IRC. This situation could
                  occur when we do not receive a W-2 wage report from the employer or self-employed
                  person and we use the information provided by the wage earner to create or amend their
                  earnings record. We provide the definition and examples of earnings or wage information
                  that does not constitute tax return information in GN 03320.001D.2.
