§301.6112-1 Material advisors of reportable transactions must keep lists of advisees, etc.
(a) In general. Each material advisor, as defined in §301.6111-3(b), with respect to any reportable transaction, as
defined in §1.6011-4(b) of this chapter, shall prepare and maintain a list in accordance with paragraph (b) of this section
and shall furnish such list to the Internal Revenue Service (IRS) in accordance with paragraph (e) of this section.
(b) Preparation and maintenance of lists—(1) In general. A separate list must be prepared and maintained for each
reportable transaction. However, one list must be maintained for substantially similar transactions. A material advisor will
have 30 calendar days from the date the list maintenance requirement first arises (see §301.6111-3(b)(4) and paragraph (a)
of this section) with respect to a reportable transaction to prepare the list that must be maintained under this section with
respect to that transaction. The Commissioner in his discretion also may provide in published guidance designating a
transaction as a reportable transaction a list preparation time period greater than 30 calendar days. If a list is requested
under this section during the list preparation time period, the request for the list will be treated as having been made on the
day after the list preparation time period ends. A list must be maintained in a form that enables the IRS to determine without
undue delay or difficulty the information required in paragraph (b)(3) of this section. The Commissioner in his discretion may
provide in published guidance a form or method for maintaining or furnishing the list.
(2) Persons required to be included on lists. A material advisor is required to maintain a list identifying each person with
respect to whom the advisor acted as a material advisor with respect to the reportable transaction. However, a material
advisor is not required to identify a person on the list if the person entered into a listed transaction or a transaction of
interest more than 6 years before the transaction was identified in published guidance as a listed transaction or a
transaction of interest.
(3) Contents. Each list must include the three components described in paragraph (b)(3)(i), (ii), and (iii) of this section.
(i) Statement. An itemized statement containing the following information—
(A) The name of each reportable transaction, the citation to the published guidance number identifying the transaction
if the transaction is a listed transaction or a transaction of interest, and the reportable transaction number obtained under
section 6111;
(B) The name, address, and TIN of each person required to be included on the list;
(C) The date on which each person required to be included on the list entered into each reportable transaction, if
known by the material advisor;
(D) The amount invested in each reportable transaction by each person required to be included on the list, if known by
the material advisor;
(E) A summary or schedule of the tax treatment that each person is intended or expected to derive from participation in
each reportable transaction; and
(F) The name of each other material advisor to the transaction, if known by the material advisor.
(ii) Description of the transaction. A detailed description of each reportable transaction that describes both the tax
structure of the transaction and the purported tax treatment of the transaction.
(iii) Documents. The following documents—
(A) A copy of any designation agreement (as described in paragraph (f) of this section) to which the material advisor is
a party; and
(B) Copies of any additional written materials, including tax analyses or opinions, relating to each reportable transaction
that are material to an understanding of the purported tax treatment or tax structure of the transaction that have been
shown or provided to any person who acquired or may acquire an interest in the transactions, or to their representatives,
tax advisors, or agents, by the material advisor or any related party or agent of the material advisor. However, a material
advisor is not required to retain earlier drafts of a document provided the material advisor retains a copy of the final
document (or, if there is no final document, the most recent draft of the document) and the final document (or most recent
draft) contains all the information in the earlier drafts of such document that is material to an understanding of the purported
tax treatment or the tax structure of the transaction.
(c) Definitions. For purposes of this section, the following terms are defined as:
(1) Material advisor. The term material advisor is defined in §301.6111-3(b).
(2) Reportable transaction. The term reportable transaction is defined in §1.6011-4(b)(1) of this chapter.

(5) Person. The term person is defined in §301.6111-3(c)(4).
(6) Related party. A person is a related party with respect to another person if such person bears a relationship to such
other person described in section 267(b) or 707(b).
(7) Tax. The term tax is defined in §301.6111-3(c)(6).

(12) Transaction of interest. The term transaction of interest is defined in §1.6011-4(b)(6) of this chapter. See also
§§20.6011-4(a), 25.6011-4(a), 26.6011-4, 31.6011-4(a), 53.6011-4(a), 54.6011-4(a), or 56.6011-4(a) of this chapter.
(d) Retention of lists. Each material advisor must maintain each component of the list described in paragraph (b)(3) of
this section in a readily accessible form for seven years following the earlier of the date on which the material advisor last
made a tax statement relating to the transaction, or the date the transaction was last entered into, if known. If the material
advisor required to prepare, maintain, and furnish the list is a corporation, partnership, or other entity (entity) that has
dissolved or liquidated before completion of the seven-year period, the person responsible under state law for winding up
the affairs of the entity must prepare, maintain and furnish each component of the list on behalf of the entity, unless the
entity submits the list to the Office of Tax Shelter Analysis (OTSA) within 60 days after the dissolution or liquidation. If state
law does not specify any person as responsible for winding up the affairs, then each of the directors of the corporation, the
general partners of the partnership, or the trustees, owners, or members of the entity are responsible for preparing,
maintaining and furnishing each component of the list on behalf of the entity, unless the entity submits the list to the OTSA
within 60 days after the dissolution or liquidation. The responsible person must also provide notice to OTSA of such
dissolution or liquidation within 60 days after the dissolution or liquidation. The list and the notice provided to OTSA must be
sent to: Internal Revenue Service, OTSA Mail Stop 4915, 1973 North Rulon White Blvd., Ogden, Utah 84404, or to such
other address as provided by the Commissioner.
(e) Furnishing of lists—(1) In general. Each material advisor responsible for maintaining a list must, upon written
request by the IRS, make each component of the list described in paragraph (b)(3) of this section available to the IRS. Each
component of the list must be furnished to the IRS in a form that enables the IRS to determine without undue delay or
difficulty the information required in paragraph (b)(3) of this section. If any component of the list is not in a form that enables
the IRS to determine without undue delay or difficulty the information required in paragraph (b)(3) of this section, the
material advisor will not be considered to have complied with the list maintenance provisions in section 6112 and this
section. A material advisor must make the list or each component of the list available to the IRS within the period prescribed
in section 6708 or published guidance relating to section 6708.
(2) Claims of privilege. Each material advisor who is required to maintain a list with respect to a reportable transaction,
must still maintain the list pursuant to the requirements of this section even if a person asserts a claim of privilege with
respect to the information specified in paragraph (b)(3)(iii)(B) of this section.
(f) Designation agreements. If more than one material advisor is required to maintain a list of persons for a reportable
transaction, in accordance with paragraph (b) of this section, the material advisors may designate by written agreement a
single material advisor (the designated material advisor) to maintain the list or a portion of the list. A designation agreement
does not relieve material advisors from their obligation to maintain a list in accordance with paragraph (b) of this section or
to furnish their list to the IRS in accordance with paragraph (e)(1) of this section, but a designation agreement may allow
one material advisor to maintain a list on behalf of the other material advisors who are a party to the designation
agreement. A material advisor is not relieved from the requirement of this section because a material advisor is unable to
obtain the list from any designated material advisor, any designated material advisor did not maintain a list, or the list
maintained by any designated material advisor is not complete. The existence of a designation agreement does not affect
the ability of the IRS to request a list from any party to the designation agreement. The IRS may request a list from any
party to the designation agreement, and the party receiving the request must furnish their list to the IRS in accordance with
paragraph (e)(1) of this section, regardless of whether their list was maintained by another party pursuant to the terms of a
designation agreement.
(g) Effective/applicability date. In general, this section applies to transactions with respect to which a material advisor
makes a tax statement under §301.6111-3 on or after August 3, 2007. However, this section applies to transactions of
interest entered into on or after November 2, 2006, with respect to which a material advisor makes a tax statement under
§301.6111-3 on or after November 2, 2006. Paragraphs (b)(1), (c)(3), (c)(12), and (f) of this section apply to transactions
with respect to which a material advisor makes a tax statement under §301.6111-3 after November 14, 2011. Otherwise,
