SUBJECT CATEGORY: Disclosure of Return Information by Certain Officers and Employees for Investigative Purposes
DOCUMENT SUMMARY: This document contains temporary regulations relating to the
disclosure of return information pursuant to section 6103(k)(6) of the
Internal Revenue Code. The temporary regulations describe the
circumstances under which officers or employees of the IRS, the IRS
Office of Chief Counsel, and the Office of Treasury Inspector General
for Tax Administration (TIGTA), in connection with official duties
relating to any examination, administrative appeal, collection
activity, administrative, civil, or criminal investigation, enforcement
activity, ruling, negotiated agreement, prefiling activity, or other
proceeding or offense under the internal revenue laws or related
statutes, or in preparation for any proceeding described in section
6103(h)(2) (or investigation which may result in such a proceeding),
may disclose return information to the extent necessary to obtain
information relating to such official duties or to accomplish properly any activity connected with
[[Page 41074]]
such official duties. The temporary regulations amend the existing
regulations to clarify and elaborate on the facts and circumstances in
which disclosure pursuant to section 6103(k)(6) is authorized. The
temporary regulations clarify that IRS and TIGTA officers and employees
make the determination, based on the facts and circumstances, at the
time of the disclosure, whether a disclosure is necessary to obtain the
information sought, and that section 6103(k)(6) does not affect the
authority or decision of IRS and TIGTA officers and employees to
initiate, or to conduct, an investigation, or to determine the nature
of the investigation. The temporary regulations clarify that the return
information of any taxpayer, not only the taxpayer under investigation,
may be disclosed when necessary to obtain the information sought in an
investigation. The temporary regulations clarify that section
6103(k)(6) permits IRS and TIGTA officers and employees to identify
themselves, their organizational affiliation with the IRS (e.g.,
Criminal Investigation (CI)) or TIGTA (e.g., Office of Investigations
(OI)), and the nature of their investigation when making oral, written,
or electronic contacts with third party witnesses. The text of the
temporary regulations also serves as the text of the proposed
regulations set forth in the notice of proposed rulemaking on this
subject in the Proposed Rules section in this issue of the Federal
Register.
SUMMARY: Return information disclosure by officers and employees for investigative purposes,
Under section 6103(a), returns and return information are confidential unless the Code authorizes disclosure. Section 6103(k)(6) authorizes an internal revenue officer or employee and an officer or employee of TIGTA, in connection with official duties relating to any audit, collection activity, civil or criminal tax investigation, or offense under the internal revenue laws or related statutes, to disclose return information to a person other than the taxpayer to whom such return information relates (or his or her representative) to the extent that such disclosure is necessary to obtain information not otherwise reasonably available with respect to the correct determination of tax, liability for tax, or the amount to be collected, or with respect to the enforcement of any other provision of the Code or related statutes. Disclosure is subject to situations and conditions prescribed by regulation.
The temporary regulations amend the existing regulations to reflect a recent legislative amendment to section 6103(k)(6). The Consolidated Appropriations Act, 2001, Public Law 106554 (114 Stat. 2763), was signed into law on December 21, 2000. Section 1 of that Act enacted into law H.R. 5662, the Community Renewal Tax Relief Act of 2000. Section 313(c) of the Community Renewal Tax Relief Act of 2000 amended section 6103(k)(6) to clarify that officers or employees of TIGTA are among those persons authorized to make disclosures under section 6103(k)(6).
The temporary regulations also clarify the standard used in determining whether disclosures are authorized under section 6103(k)(6). Recent litigation indicates that there is some confusion as to the authority of IRS (and now TIGTA) officers and employees to make disclosures in certain situations under section 6103(k)(6). The temporary regulations seek to address these issues. In particular, the temporary regulations address the issues surrounding the disclosures that occur when IRS or TIGTA officers and employees introduce themselves to third party witnesses or communicate in writing using, e.g., official letterhead that reveals affiliation with IRS or TIGTA. The temporary regulations also clarify that section 6103(k)(6) does not limit IRS or TIGTA officers and employees with respect to the initiation or conduct of an investigation. Finally, the temporary regulations clarify that section 6103 does not require IRS and TIGTA officers or employees to contact a taxpayer for information before contacting third party witnesses.
The temporary regulations amend the existing regulations to clarify that there is a single, objective standard for all disclosures under section 6103(k)(6). This standard is embodied in the definitions of the terms disclosure of return information to the extent necessary and information not otherwise reasonably available.
The definition of disclosure of return information to the extent necessary is a disclosure of return information that an IRS or TIGTA officer or employee, based on the facts and circumstances known to the officer or employee at the time of the disclosure, reasonably believes is necessary to obtain information to perform properly the official duties described by the temporary regulations, or to accomplish properly the activities connected with carrying out those official duties. The term necessary in this context does not mean essential or indispensable, but rather appropriate and helpful in obtaining the information sought.
The definition of information not otherwise reasonably available is information that an IRS or TIGTA officer or employee reasonably believes, under the facts and circumstances known to the officer or employee at the time of a disclosure, cannot be obtained in a sufficiently accurate or probative form, or in a timely manner, and without impairing the proper performance of the official duties described by the temporary regulations, without making the disclosure. Corroboration of information provided by, or concerning, a taxpayer is, by definition, information not otherwise reasonably available from the taxpayer. In criminal cases, corroboration of information provided by the taxpayer is essential. See Smith v. United States, 348 U.S. 147 (1954).
The temporary regulations clarify that section 6103(k)(6) does not
alter or affect the authority of IRS and TIGTA officers or employees to
decide whether or how to conduct an investigation. For example, in an
action for wrongful disclosure under section 7431, the inquiry is
whether the particular disclosure at issue was consistent with section
6103(k)(6), not the necessity of conducting an investigation or the
appropriateness of the means or methods chosen to conduct the
investigation. Thus, the temporary regulations remove the term
necessary from several places in the existing regulations where the
term may have implied a requirement, under section 6103(k)(6), that the
information sought be necessary to or for an investigation (e.g., Sec. 301.6103(k)(6)1(a)(``disclose * * * to obtain necessary
information'')). Removal of the term necessary in these instances
clarifies that the standard is whether disclosure is necessary to
obtain the information sought, not whether the information sought is
necessary for the investigation. See Barrett v. United States, 795 F.2d 446 (5th Cir. 1986).
The temporary regulations also address certain issues that have
arisen in criminal investigations, although similar issues may arise in
civil investigations. Criminal investigations typically involve
obtaining evidence and verifying taxpayersupplied information through
contacts with third party witnesses. A disclosure that a taxpayer is
under criminal investigation may occur by various means including, but
not limited to, direct oral, written, or electronic disclosure, or indirect
[[Page 41075]]
disclosure by the introduction of the special agent through the
presentation of a CI or OI badge, credential, or business card, or
through the use of information document requests, summonses, or
correspondence, about an identified taxpayer, on CI or OI letterhead or
that bears a CI or OI return address or signature block. In litigation,
taxpayers have asserted that CI special agents, by various means,
wrongfully disclosed the criminal nature of the investigation of the
taxpayers in the course of conducting third party witness interviews or
inquiries. See, e.g., Comyns v. United States, 155 F. Supp. 2d 1344
(S.D. Fla. 2001), aff'd, 287 F.3d 1034 (11th Cir. 2002); Payne v.
United States, 91 F. Supp. 2d 1014 (S.D. Tex. 1999), rev'd, 289 F.3d
377 (5th Cir. 2002); Gandy v. United States, 991 U.S. Tax Cas. (CCH)
para. 50,237 (E.D. Tex. 1999), aff'd, 234 F.3d 281 (5th Cir. 2000);
Rhodes v. United States, 903 F. Supp. 819 (M.D. Pa. 1995); Diamond v. United States, 944 F.2d 431 (8th Cir. 1991).
When CI special agents disclose to third party witnesses that a
taxpayer is under criminal investigation, there is a risk that the
disclosure may adversely affect the taxpayer's reputation, particularly
if the third party witnesses have no prior independent knowledge of the
investigation. The government and third party witnesses have equally
important interests at stake: The CI special agents' authority to
accurately identify themselves so as not to mislead third party
witnesses, and the third party witnesses' interest in knowing that the
inquiry involves a criminal investigation to fairly assess the
situation and protect their own interests. See Roebuck v. United
States, 83 A.F.T.R.2d (RIA) para. 992947 (E.D.N.C. 1999), aff'd, 84
A.F.T.R.2d (RIA) para. 997051 (4th Cir. 1999). This issue has
concerned the Department of the Treasury and the Staff of the Joint
Committee on Taxation, both of which have recommended legislation to
clarify that CI special agents may identify themselves as CI special
agents when contacting third party witnesses in the course of a criminal investigation. See Study of PresentLaw Taxpayer
Confidentiality and Disclosure Provisions as Required by Section 3802
of the Internal Revenue Service Restructuring and Reform Act of 1998,
Vol. I: Study of General Disclosure Provisions (JCS100), at 20811,
Joint Committee on Taxation, January 28, 2000; Report to the Congress
on Scope and Use of Taxpayer Confidentiality and Disclosure Provisions,
Vol. I: Study of General Provisions, at 5152, Office of Tax Policy,
Department of the Treasury, October 2000. The temporary regulations
clarify that section 6103(k)(6) permits, but does not require, IRS or
TIGTA officers or employees, including CI or OI special agents, to
identify themselves, their organizational affiliation with the IRS or
TIGTA, and the nature of the investigation, when making oral, written, or electronic contacts with third party witnesses.
Moreover, the temporary regulations do not require IRS or TIGTA officers or employees to contact a taxpayer for information before contacting a third party witness. The temporary regulations clarify that, if an IRS or TIGTA officer or employee reasonably believes, under the facts and circumstances, at the time of a disclosure, that information cannot be obtained from a taxpayer in a sufficiently accurate or probative form, or in a timely manner, without impairing the proper performance of official duties, then the officer or employee may disclose taxpayer identity or other return information in seeking information from a third party. For example, a taxpayer may be a reasonable source of routine business records, but not of records detailing alleged illegal transactions or sources of income. The facts and circumstances will help determine the necessity of the disclosures, but IRS and TIGTA officers or employees have wide latitude to determine whether the taxpayer is a reasonable source of information. The temporary regulations clarify that disclosures are authorized to verify independently, or to corroborate, from third party sources, information obtained from or concerning the taxpayer.
The temporary regulations expand upon the list of official duties relating to tax administration for which disclosure, pursuant to section 6103(k)(6), is authorized, and clarify that this list is not exhaustive. Finally, the temporary regulations retain the authority for IRS and TIGTA officers or employees to make section 6103(k)(6) disclosures in certain personnel or claimant representative matters. Special Analyses
It has been determined that this Treasury decision is not a significant regulatory action as defined in Executive Order 12866. Therefore, a regulatory assessment is not required. It has also been determined that 5 U.S.C. 553(b), the Administrative Procedure Act, does not apply to these regulations, and because the regulation does not impose a collection of information on small entities, the Regulatory Flexibility Act (5 U.S.C. chapter 6) does not apply. Pursuant to section 7805(f), these temporary regulations will be submitted to the Chief Counsel for Advocacy of the Small Business Administration for comment on its impact on small business.

administrative appeals process and any ruling, negotiated agreement, or prefiling process.
(2) Disclosure of return information for the purpose of obtaining
information to carry out properly the official duties described by this
paragraph, or any activity connected with the official duties, is
authorized only if the internal revenue or TIGTA employee reasonably
believes, under the facts and circumstances, at the time of a
disclosure, the information is not otherwise reasonably available, or
if the activity connected with the official duties cannot occur properly without the disclosure.
(3) Internal revenue and TIGTA employees may identify themselves,
their organizational affiliation with the Internal Revenue Service
(IRS) (e.g., Criminal Investigation (CI)) or TIGTA (e.g., Office of
Investigations (OI)), and the nature of their investigation, when
making an oral, written, or electronic contact with a third party
witness through the use and presentation of any identification media
(including, but not limited to, an IRS or TIGTA badge, credential, or
business card) or through the use of an information document request,
summons, or correspondence on IRS or TIGTA letterhead or which bears a
return address or signature block that reveals affiliation with the IRS or TIGTA.
(4) This section does not address or affect the requirements under section 7602(c) (relating to contact of third parties).
(b) Disclosure of return information in connection with certain
personnel or claimant representative matters. In connection with
official duties relating to any investigation concerned with
enforcement of any provision of the Internal Revenue Code, including
enforcement of any rule, or directive prescribed by the Secretary or
the Commissioner of Internal Revenue under any provision of the
Internal Revenue Code, or the enforcement of any provision related to
tax administration under the jurisdiction of the IRS or TIGTA, that
affects or may affect the personnel or employment rights or status, or
civil or criminal liability, of any former, current, or prospective
employee of the Treasury Department or the rights of any person who is,
or may be, a party to an administrative action or proceeding pursuant
to 31 U.S.C. 330 (relating to practice before the Treasury Department),
an internal revenue or TIGTA employee is authorized to disclose return
information for the purpose of obtaining, verifying, or establishing
other information which is or may be relevant and material to the investigation.
(c) Definitions. The following definitions apply to this section
(1) Disclosure of return information to the extent necessary means
a disclosure of return information which an internal revenue or TIGTA
employee, based on the facts and circumstances, at the time of the
disclosure, reasonably believes is necessary to obtain information to
perform properly the official duties described by this section, or to
accomplish properly the activities connected with carrying out those
official duties. The term necessary in this context does not mean
essential or indispensable, but rather appropriate and helpful in
obtaining the information sought. Nor does necessary in this context
refer to the necessity of conducting an investigation or the
appropriateness of the means or methods chosen to conduct the
investigation. Section 6103(k)(6) does not limit or prescribe IRS or
TIGTA officers and employees with respect to the decision to initiate
or how to conduct an investigation. Disclosures under this
subparagraph, however, may not be made indiscriminately or solely for
the benefit of the recipient or as part of a negotiated quid pro quo
arrangement. This paragraph (c)(1) is illustrated by the following examples:
Example 1. A revenue agent contacts a taxpayer's customer
regarding the customer's purchases made from the taxpayer during the
year under investigation. The revenue agent is able to obtain the
purchase information only by disclosing the taxpayer's identity and the fact of the investigation. Depending on the facts and
circumstances known to the revenue agent at the time of the
disclosure, such as the way the customer maintains his records, it
also may be necessary for the revenue agent to inform the customer
of the date of the purchases and the types of merchandise involved for the customer to find the purchase information.
Example 2. A revenue agent contacts a third party witness to obtain copies of invoices of sales made to a taxpayer under examination. The third party witness provides copies of the sales invoices in question and then asks the revenue agent for the current address of the taxpayer because the taxpayer still owes money to the third party witness. The revenue agent may not disclose that current address because this disclosure would be only for the benefit of the third party witness and not necessary to obtain information for the examination.
Example 3. A revenue agent contacts a third party witness to
obtain copies of invoices of sales made to a taxpayer under
examination. The third party witness agrees to provide copies of the
sales invoices in question only if the revenue agent provides him
with the current address of the taxpayer because the taxpayer still
owes money to the third party witness. The revenue agent may not
disclose that current address because this disclosure would be a negotiated quid pro quo arrangement.
(2) Disclosure of return information to accomplish properly an
activity connected with official duties means a disclosure of return
information to carry out a function associated with official duties
generally consistent with established practices and procedures. [[Page 41077]]
This paragraph (c)(2) is illustrated by the following example:
Example. A taxpayer failed to file an income tax return and pay the taxes owed. After the taxes were assessed and the taxpayer was notified of the deficiencies, a revenue officer filed a notice of federal tax lien and then served a notice of levy on the taxpayer's bank. The notices of lien and levy contained the taxpayer's name, social security number, amount of outstanding liability, and the tax period and type of tax involved. The taxpayer's assets were levied to satisfy the tax debt, but it was determined that, prior to the levy, the revenue officer failed to issue the taxpayer a notice of right to hearing before the levy, as required by section 6330. The disclosure of the taxpayer's return information in the notice of levy is authorized by section 6103(k)(6) despite the revenue officer's failure to issue the notice of right to hearing. The ultimate validity of the underlying levy is irrelevant to the issue of whether the disclosure was authorized by section 6103(k)(6). (3) Information not otherwise reasonably available means information that an internal revenue or TIGTA employee reasonably believes, under the facts and circumstances, at the time of a disclosure, cannot be obtained in a sufficiently accurate or probative form, or in a timely manner, and without impairing the proper performance of the official duties described by this section, without making the disclosure. This definition does not require or create the presumption or expectation that an internal revenue or TIGTA employee must seek information from a taxpayer or authorized representative prior to contacting a third party witness in an investigation. Moreover, an internal revenue or TIGTA employee may make a disclosure to a third party witness to corroborate information provided by a taxpayer. This paragraph (c)(3) is illustrated by the following examples:
Example 1. A revenue agent is conducting an examination of a taxpayer. The taxpayer refuses to cooperate or provide any information to the revenue agent. Information relating to the taxpayer's examination would be information not otherwise reasonably available because of the taxpayer's refusal to cooperate and supply any information to the revenue agent. Therefore, the revenue agent may seek information from a third party witness. Neither the Internal Revenue Code, IRS procedures, nor these regulations require repeated contacting of an uncooperative taxpayer.
Example 2. A special agent is conducting a criminal
investigation of a taxpayer. The special agent has acquired certain
information from the taxpayer. Although the special agent has no
specific reason to disbelieve the taxpayer's information, the
special agent contacts several third party witnesses to confirm the
information. The special agent may contact third party witnesses to
verify the correctness of the information provided by the taxpayer
because the IRS is not required to rely solely on information
provided by a taxpayer, and a special agent may take appropriate
steps, including disclosures to third party witnesses under section
6103(k)(6), to verify independently or corroborate information obtained from a taxpayer.
(4) Internal revenue employee means, for purposes of this section,
an officer or employee of the IRS or Office of Chief Counsel for the IRS.
(5) TIGTA employee means an officer or employee of the Office of Treasury Inspector General for Tax Administration.
(d) Examples. The following examples illustrate the application of this section:
Example 1. A revenue agent is conducting an examination of a taxpayer. The taxpayer has been very cooperative and has supplied copies of invoices as requested. Some of the taxpayer's invoices show purchases that seem excessive in comparison to the size of the taxpayer's business. The revenue agent contacts the taxpayer's suppliers for the purpose of corroborating the invoices the taxpayer provided. In contacting the suppliers, the revenue agent discloses the taxpayer's name, the dates of purchase, and the type of merchandise at issue. These disclosures are permissible under section 6103(k)(6) because, under the facts and circumstances known to the revenue agent at the time of the disclosures, the disclosures were necessary to obtain information (corroboration of invoices) not otherwise reasonably available because suppliers would be the only source available for corroboration of this information.
Example 2. A revenue agent is conducting an examination of a taxpayer. The revenue agent asks the taxpayer for business records to document the deduction of the cost of goods sold shown on Schedule C of the taxpayer's return. The taxpayer will not provide the business records to the revenue agent, who contacts a third party witness for verification of the amount on the Schedule C. In the course of the contact, the revenue agent shows the Schedule C to the third party witness. This disclosure is not authorized under section 6103(k)(6). Section 6103(k)(6) permits disclosure only of return information, not the return (including schedules and attachments) itself. If necessary, a revenue agent may disclose return information extracted from a return when questioning a third party witness. Thus, the revenue agent could have extracted the amount of cost of goods sold from the Schedule C and disclosed that amount to the third party witness.
Example 3. A special agent is conducting a criminal investigation of a taxpayer, a doctor, for tax evasion.
Notwithstanding the records provided by the taxpayer and the
taxpayer's bank, the special agent decided to obtain information
from the taxpayer's patients to verify amounts paid to the taxpayer
for his services. Accordingly, the special agent sent letters to the
taxpayer's patients to verify these amounts. In the letters, the
agent disclosed that he was a special agent with IRSCI and that he
was conducting a criminal investigation of the taxpayer. Section
6103(k)(6) permits these disclosures to confirm the taxpayer's
income. The decision of whether to verify information already
obtained is a matter of investigative judgment and is not limited by section 6103(k)(6).
Example 4. Corporation A requests a private letter ruling (PLR)
as to the taxability of a merger with Corporation B. Corporation A
has submitted insufficient information about Corporation B to
consider properly the tax consequences of the proposed merger.
Accordingly, information is needed from Corporation B. Under section
6103(k)(6), the IRS may disclose Corporation A's return information
to Corporation B to the extent necessary to obtain information from
Corporation B for the purpose of properly considering the tax
consequences of the proposed merger that is the subject of the PLR.
(e) Effective date. This section is applicable on July 10, 2003. Robert E. Wenzel,
Deputy Commissioner of Internal Revenue.
