(1) Tax Division Central Classification Cards, Index Docket Cards, and Associated Records - Criminal Tax Cases (JUSTICE/TAX-001) - Limited Access.

(2) These exemptions apply to the extent that information in these systems is subject to exemption pursuant to 5 U.S.C. 552a(j)(2).

(1) (c)(3). The release of the disclosure accounting, for disclosures made pursuant to subsection (b) of the Act, including those permitted under the routine uses published for those systems of records, would enable the subject of an investigation of an actual or potential criminal tax case to determine whether he or she is the subject of investigation, to obtain valuable information concerning the nature of that investigation and the information obtained, and to determine the identity of witnesses or informants. Such access to investigative information would, accordingly, present a serious impediment to law enforcement. In addition, disclosure of the accounting would constitute notice to the individual of the existence of a record even though such notice requirement under subsection (f)(1) is specifically exempted for these systems of records.

(2) (c)(4). Since an exemption is being claimed for subsection (d) of the Act (Access to Records) this subsection is inapplicable to the extent that these systems of records are exempted from subsection (d).

(3) (d)(1); (d)(2); (d)(3); (d)(4). Access to the records contained in these systems would inform the subject of an actual or potential criminal tax investigation of the existence of that investigation, of the nature and scope of the information and evidence obtained as to his or her activities, and of the identity of witnesses or informants. Such access would, accordingly, provide information that could enable the subject to avoid detection, apprehension and prosecution. This result, therefore, would constitute a serious impediment to effective law enforcement not only because it would prevent the successful completion of the investigation but also because it could endanger the physical safety of witnesses or informants, lead to the improper influencing of witnesses, the destruction of evidence, or the fabrication of testimony.

(4) (e)(1). The notices for these systems of records published in the Federal Register, set forth the basic statutory or related authority for maintenance of these systems. However, in the course of criminal tax and related law enforcement investigations, cases, and matters, the Tax Division will occasionally obtain information concerning actual or potential violations of law that may not be technically within its statutory or other authority or may compile information in the course of an investigation which may not be relevant to a specific prosecution. In the interests of effective law enforcement, it is necessary to retain some or all of such information in these systems of records since it can aid in establishing patterns of criminal activity and can provide valuable leads for Federal and other law enforcement agencies.

(5) (e)(2). In a criminal tax investigation or prosecution, the requirement that information be collected to the greatest extent practicable from the subject individual would present a serious impediment to law enforcement because the subject of the investigation or prosecution would be placed on notice as to the existence of the investigation and would therefore be able to avoid detection or apprehension, influence witnesses improperly, destroy evidence, or fabricate testimony.

(6) (e)(3). The requirement that individuals supplying information be provided with a form stating the requirements of subsection (e)(3) would constitute a serious impediment to law enforcement in that it could compromise the existence of a confidential investigation or reveal the identity of witnesses or confidential informants.

(7) (e)(4) (G) and (H). Since an exemption is being claimed for subsections (f) (Agency Rules) and (d) (Access to Records) of the Act these subsections are inapplicable to the extent that these systems of records are exempted from subsection (f) and (d).

(8) (e)(4)(I). The categories of sources of the records in the systems have been published in the Federal Register in broad generic terms in the belief that this is all that subsection (e)(4)(I) of the Act requires. In the event, however, that this subsection should be interpreted to require more detail as to the identity of sources of the records in these systems, exemption from this provision is necessary in order to protect the confidentiality of the sources of criminal tax and related law enforcement information. Such exemption is further necessary to protect the privacy and physical safety of witnesses and informants.

(9) (e)(5). In the collection of information for criminal tax enforcement purposes it is impossible to determine in advance what information is accurate, relevant, timely, and complete. With the passage of time, seemingly irrelevant or untimely information may acquire new significance as further investigation brings new details to light. Furthermore, the accuracy of such information can often only be determined in a court of law. The restrictions of subsection (e)(5) would restrict the ability of government attorneys in exercising their judgment in reporting on information and investigations and impede the development of criminal tax information and related data necessary for effective law enforcement.

(10) (e)(8). The individual notice requirements of subsection (e)(8) could present a serious impediment to law enforcement as this could interfere with the ability to issue warrants or subpoenas and could reveal investigative techniques, procedures, or evidence.

(11) (f). Procedures for notice to an individual pursuant to subsection (f)(1) as to the existence of records pertaining to him dealing with an actual or potential criminal tax, civil tax, or regulatory investigation or prosecution must be exempted because such notice to an individual would be detrimental to the successful conduct and/or completion or an investigation or prosecution pending or future. In addition, mere notice of the fact of an investigation could inform the subject or others that their activities are under or may become the subject of an investigation and could enable the subjects to avoid detection or apprehension, to influence witnesses improperly, to destroy evidence, or to fabricate testimony.

Since an exemption is being claimed for subsection (d) of the Act (Access to Records) the rules required pursuant to subsection (f) (2) through (5) are inapplicable to these systems of records to the extent that these systems of records are exempted from subsection (d).

(12) (g). Since an exemption is being claimed for subsections (d) (Access to Records) and (f) (Agency Rules) this section is inapplicable, and is exempted for the reasons set forth for those subsections, to the extent that these systems of records are exempted from subsections (d) and (f).

(1) Tax Division Central Classification Cards, Index Docket Cards, and Associated Records - Civil Tax Cases (JUSTICE/TAX-002) - Limited Access.

These exemptions apply to the extent that information in this system is subject to exemption pursuant to 5 U.S.C. 552a(k)(2).

(1) (c)(3). The release of the disclosure accounting, for disclosures made pursuant to subsection (b) of the Act, including those permitted under the routine uses published for this system of records, would enable the subject of an investigation of an actual or potential civil tax case to determine whether he or she is the subject of investigation, to obtain valuable information concerning the nature of that investigation and the information obtained, and to determine the identity of witnesses or informants. Such access to investigative information would, accordingly, present a serious impediment to law enforcement. In addition, disclosure of the accounting would constitute notice to the individual of the existence of a record even though such notice requirement under subsection (f)(1) is specifically exempted for this system of records.

(2) (d)(1); (d)(2); (d)(3); (d)(4). Access to the records contained in this system would inform the subject of an actual or potential civil tax investigation of the existence of that investigation, of the nature and scope of the information and evidence obtained as to his or her activities and of the identity of witnesses or informants. Such access would, accordingly, provide information that could enable the subject to avoid detection. This result, therefore, would constitute a serious impediment to effective law enforcement not only because it would prevent the successful completion of the investigation but also because it could endanger the physical safety of witnesses or informants, lead to the improper influencing of witnesses, the destruction of evidence, or the fabrication of testimony.

(3) (e)(1). The notices for this system of records published in the Federal Register set forth the basic statutory or related authority for maintenance of this system. However, in the course of civil tax and related law enforcement investigations, cases and matters, the Tax Division will occasionally obtain information concerning actual or potential violations of law that are not strictly or technically within its statutory or other authority or may compile information in the course of an investigation which may not be relevant to a specific case. In the interests of effective law enforcement, it is necessary to retain some or all of such information in this system of records since it can aid in establishing patterns of tax compliance and can provide valuable leads for Federal and other law enforcement agencies.

(4) (e)(4) (G) and (H). Since an exemption is being claimed for subsections (f) (Agency Rules) and (d) (Access to Records) of the Act these subsections are inapplicable to the extent that this system of records is exempted from subsection (f) and (d).

(5) (e)(4)(I). The categories of sources of the records in this system have been published in the Federal Register in broad generic terms in the belief that this is all that subsection (e)(4)(I) of the Act requires. In the event, however, that this subsection should be interpreted to require more detail as to the identity of sources of the records in this system, exemption from this provision is necessary in order to protect the confidentiality of the sources of civil tax and related law enforcement information. Such exemption is further necessary to protect the privacy and physical safety of witnesses and informants.

(6) (f). Procedures for notice to an individual pursuant to subsection (f)(1) as to existence of records pertaining to the individual dealing with an actual or potential criminal tax, civil tax, or regulatory investigation or prosecution must be exempted because such notice to an individual would be detrimental to the successful conduct and/or completion of an investigation or case, pending or future. In addition, mere notice of the fact of an investigation could inform the subject or others that their activities are under or may become the subject of an investigation and could enable the subjects to avoid detection, to influence witnesses improperly, to destroy evidence, or to fabricate testimony.

Since an exemption is being claimed for subsection (d) of the Act (Access to Records) the rules required pursuant to subsection (f) (2) through (5) are inapplicable to this system of records to the extent that this system of records is exempted from subsection (d).

(1) From subsection (c)(3) because an accounting could reveal the identity of confidential sources and result in an unwarranted invasion of the privacy of others. Many persons are contacted who, without an assurance of anonymity, refuse to provide information concerning an applicant for a position with the Tax Division. Disclosure of an accounting could reveal the identity of a source of information and constitutes a breach of the promise of confidentiality by the Tax Division. This would result in the reduction in the free flow of information vital to a determination of an applicant's qualifications and suitability for federal employment.

(2) From subsection (d)(1) because disclosure of records in the system could reveal the identity of confidential sources and result in an unwarranted invasion of the privacy of others. Many persons are contacted who, without an assurance of anonymity, refuse to provide information concerning an applicant for a Tax Division position. Access could reveal the identity of the source of the information and constitute a breach of the promise of confidentiality on the part of the Tax Division. Such breaches ultimately would restrict the free flow of information vital to a determination of an applicant's qualifications and suitability.
