or a listed transaction, as those terms are defined in such section or
regulations, must attach a duplicate of such disclosure statement to the
return or report required to be filed by such taxpayer or person for the
taxable year under article nine, nine-A, twenty-two or thirty-three of

other form of published guidance.

any material aid, assistance, or advice with respect to organizing,
managing, promoting, selling, implementing, or carrying out any
reportable transaction.

(2) Such duplicate statement or return must be filed within sixty days
of the later of:

this subdivision first applies, or

(C) ninety days after the enactment of this section.

(c) Every person who is required to maintain a list of persons
pursuant to section six thousand one hundred twelve of the internal
revenue code, or the regulations promulgated thereunder, must maintain a
duplicate of such list if any of the conditions described in paragraph
one of subdivision (b) of this section applies to such person and must
furnish a copy thereof to the commissioner within twenty days after
written request is made for such list by the commissioner.

(d) Every person required by this section to disclose any transaction,
file any duplicate return, or maintain any list shall retain all
relevant correspondence, memoranda, notes, valuation studies, meeting
minutes, spreadsheets, models, opinions, records required to be retained
pursuant to section six thousand eleven of the internal revenue code, or
the regulations promulgated thereunder, and all other records or
documents related to the disclosure, filing and list maintenance
requirements of this section for six years and must make such
information available for inspection by the commissioner in connection
with any examination.

(e) The filing, disclosure and retention requirements of this section
shall be in addition to any other filing, disclosure or retention
requirements, general or specific, provided by law. The commissioner may
require electronic filing or disclosure of any or all submissions
required under this section, shall have the authority to prescribe
whether a signature, including an electronic signature, is required on
any or all filings or disclosures under this section. If an electronic
signature is so required, it shall be in a form consistent with the
provisions of the electronic signatures and records act of the state
technology law.
