§ 6227. Administrative adjustment requests
(a) General rule
A partner may file a request for an administrative adjustment of partnership items for any partnership taxable year at any time which is—
(1) within 3 years after the later of—
(A) the date on which the partnership return for such year is filed, or
(B) the last day for filing the partnership return for such year (determined without regard to extensions), and
(2) before the mailing to the tax matters partner of a notice of final partnership administrative adjustment with respect to such taxable year.
(b) Special rule in case of extension of period of limitations under section 6229
The period prescribed by subsection (a)(1) for filing of a request for an administrative adjustment shall be extended—

(2) for 6 months thereafter.
(c) Requests by tax matters partner on behalf of partnership
(1) Substituted return
If the tax matters partner—
(A) files a request for an administrative adjustment, and
(B) asks that the treatment shown on the request be substituted for the treatment of partnership items on the partnership return to which the request relates,
the Secretary may treat the changes shown on such request as corrections of mathematical or clerical errors appearing on the partnership return.
(2) Requests not treated as substituted returns
(A) In general
If the tax matters partner files an administrative adjustment request on behalf of the partnership which is not treated as a substituted return under paragraph (1), the Secretary may, with respect to all or any part of the requested adjustments—
(i) without conducting any proceeding, allow or make to all partners the credits or refunds arising from the requested adjustments,
(ii) conduct a partnership proceeding under this subchapter, or
(iii) take no action on the request.
(B) Exceptions
Clause (i) of subparagraph (A) shall not apply with respect to a partner after the day on which the partnership items become nonpartnership items by reason of 1 or more of the events described in subsection (b) of section 6231.
(3) Request must show effect on distributive shares
The tax matters partner shall furnish with any administrative adjustment request on behalf of the partnership revised schedules showing the effect of such request on the distributive shares of the partners and such other information as may be required under regulations.
(d) Other requests
If any partner files a request for an administrative adjustment (other than a request described in subsection (c)), the Secretary may—
(1) process the request in the same manner as a claim for credit or refund with respect to items which are not partnership items,
(2) assess any additional tax that would result from the requested adjustments,
(3) mail to the partner, under subparagraph (A) of section 6231(b)(1) (relating to items becoming nonpartnership items), a notice that all partnership items of the partner for the partnership taxable year to which such request relates shall be treated as nonpartnership items, or
(4) conduct a partnership proceeding.
(e) Requests with respect to bad debts or worthless securities
In the case of that portion of any request for an administrative adjustment which relates to the deductibility by the partnership under section 166 of a debt as a debt which became worthless, or under section 165(g) of a loss from worthlessness of a security, the period prescribed in subsection (a)(1) shall be 7 years from the last day for filing the partnership return for the year with respect to which such request is made (determined without regard to extensions).
