[[Page 240]]

means any tax imposed by subsection (b) of section 4941, 4942, 4943, 
4944, 4945, 4951, 4952, 4955, 4958, 4971, or 4975. A second tier tax may 
also be referred to as an ``additional tax'' in parts 53 and 54.
    (c) Taxable event. For purposes of this subpart K, the term taxable 
event means any act, or failure to act, giving rise to liability for tax 
under section 4941, 4942, 4943, 4944, 4945, 4951, 4952, 4955, 4958, 
4971, or 4975.
    (d) Correct--(1) In general. Except as provided in subparagraph (2), 
the term correct has the same meaning for purposes of this subpart K as 
in the section which imposes the second tier tax or the regulations 
thereunder.
    (2) Special rules. The term correct means--
    (i) For a second tier tax imposed by section 4942(b), reducing the 
amount of the undistributed income to zero,
    (ii) For a second tier tax imposed by section 4943(b), reducing the 
amount of the excess business holdings to zero, and
    (iii) For a second tier tax imposed by section 4944(b), removing the 
investment from jeopardy.
    (e) Correction period--(1) In general. The correction period with 
respect to any taxable event shall begin with the date on which the 
taxable event occurs and shall end 90 days after the date of mailing of 
a notice of deficiency under section 6212 with respect to the second 
tier tax imposed with respect to the taxable event.
    (2) Extensions of correction period. The correction period referred 
to in subparagraph (1) of this paragraph shall be extended by any period 
in which a deficiency cannot be assessed under section 6213(a). In 
addition, the correction period referred to in subparagraph (1) of this 
paragraph (e) shall be extended in accordance with subparagraph (3), 
(4), and (5) of this paragraph except that subparagraph (4), or (5) 
shall not operate to extend a correction period with respect to which a 
taxpayer has filed a petition with the United States Tax Court for 
redetermination of a deficiency within the time prescribed by section 
6213(a).
    (3) Extensions by Commissioner. The correction period referred to in 
subparagraph (1) of this paragraph may be extended by any period which 
the Commissioner determines is reasonable and necessary to bring about 
correction (including, for taxes imposed by section 4975, equitable 
relief sought by the Secretary of Labor) of the taxable event. The 
Commissioner ordinarily will not extend the correction period unless the 
following factors are present.
    (i) The taxpayer on whom the second tier tax is imposed, the 
Secretary of Labor (for taxes imposed by section 4975), or an 
appropriate State officer (as defined in section 6104(c)(2)) is actively 
seeking in good faith to correct the taxable event;
    (ii) Adequate corrective action cannot reasonably be expected to 
result during the unextended correction period;
    (iii) For taxes imposed by section 4975, the Secretary of Labor 
requests the extension because subdivision (ii) applies; and
    (iv) For taxes imposed by chapter 42 (other than taxes imposed by 
section 4940), the taxable event appears to have been an isolated 
occurrence so that it appears unlikely that similar taxable events will 
occur in the future.
    (4) Extension for payment of first tier tax. If, within the 
unexpected correction period, the taxpayer pays the full amount of the 
first tier tax imposed with respect to the taxable event the 
Commissioner shall extend the correction period to the later of--
    (i) Ninety days after the payment of the first tier tax, or
    (ii) The last day of the correction period determined without regard 
to this paragraph.
    (5) Extensions for filing claim for refund or refund suit. If prior 
to the expiration of the correction period (including extensions) a 
claim for refund is filed with respect to payment of the full amount of 
the first tier tax imposed with respect to the taxable event, the 
Commissioner shall extend the correction period during the pendency of 
the claim plus an additional 90 days. If within that time a suit or 
proceeding referred to in section 7422(g) with respect to the claim is 
filed, the Commissioner shall extend the correction period until the 
determination in the suit for refund (determined without regard to a 
supplemental proceeding under

[[Page 241]]

section 4861(b)) is final, determined under Sec. 301.7422-2(a).
    (6) End of correction period if waiver accepted. If the notice of 
deficiency referred to in paragraph (1) is not mailed because there is a 
waiver of the restrictions on assessment and collection of the 
deficiency or because the deficiency is paid, the correction period will 
end with the end of the collection prohibition period described in Sec. 
53.4961-2(e)(5).
    (7) Date on which taxable event occurs. For purposes of subparagraph 
(1), the taxable event shall be treated as occurring--
    (i) Under section 4942, on the first day of the taxable year for 
which there is undistributed income,
    (ii) Under section 4943, on the first day on which there are excess 
business holdings,
    (iii) Under section 4971, on the last day of the plan year in which 
there is an accumulated funding deficiency, and
    (iv) In all other cases, the date on which the event occurred.
    (f) Effective date. The provisions of this subpart K are effective 
with respect to second tier taxes assessed after December 24, 1980. The 
preceding sentence shall not be construed to permit the assessment of a 
tax in a case to which, on December 24, 1980, the doctrine of res 
judicata applied.
