‘‘(B) a partnership does not make such an
election but in filing its return for any partner-
ship taxable year fails to take fully into account
any partnership adjustment as required under
paragraph (1), or

reduction in a credit which exceeds the
amount of such credit determined for the
partnership taxable year in which the adjust-

117

taken into account under this subsection for any
partnership taxable year shall continue to be treated

‘‘(b) PARTNERSHIP LIABLE
FOR INTEREST
AND
PENALTIES.—
‘‘(1) IN
GENERAL.—If a partnership adjust-
ment takes effect during any partnership taxable
year and such adjustment results in an imputed
underpayment for the adjusted year, the partner-
ship—
‘‘(A) shall pay to the Secretary interest
computed under paragraph (2), and
‘‘(B) shall be liable for any penalty, addi-
tion to tax, or additional amount as provided in
paragraph (3).
‘‘(2) DETERMINATION OF AMOUNT OF INTER-
EST.—The interest computed under this paragraph
with respect to any partnership adjustment is the in-
terest which would be determined under chapter
67—
118
‘‘(A) on the imputed underpayment deter-
mined under paragraph (4) with respect to such
adjustment,
‘‘(B) for the period beginning on the day
after the return due date for the adjusted year
and ending on the return due date for the part-
nership taxable year in which such adjustment
takes effect (or, if earlier, in the case of any ad-
justment to which subsection (a)(2) applies, the
date on which the payment under subsection
(a)(2) is made).
Proper adjustments in the amount determined under
the preceding sentence shall be made for adjust-
ments required for partnership taxable years after
the adjusted year and before the year in which the
partnership adjustment takes effect by reason of
such partnership adjustment.
‘‘(3) PENALTIES.—A partnership shall be liable
for any penalty, addition to tax, or additional
amount for which it would have been liable if such
partnership had been an individual subject to tax
under chapter 1 for the adjusted year and the im-
puted underpayment determined under paragraph
(4) were an actual underpayment (or understate-
ment) for such year.
119
‘‘(4) IMPUTED UNDERPAYMENT.—For purposes
of this subsection, the imputed underpayment deter-
mined under this paragraph with respect to any
partnership adjustment is the underpayment (if any)
which would result—
‘‘(A) by netting all adjustments to items of
income, gain, loss, or deduction and by treating
any net increase in income as an underpayment
equal to the amount of such net increase multi-
plied by the highest rate of tax in effect under
section 1 or 11 for the adjusted year, and
‘‘(B) by taking adjustments to credits into
account as increases or decreases (whichever is
appropriate) in the amount of tax.
For purposes of the preceding sentence, any net de-
crease in a loss shall be treated as an increase in in-
come and a similar rule shall apply to a net increase
in a loss.
‘‘(c) ADMINISTRATIVE PROVISIONS.—
‘‘(1) IN GENERAL.—Any payment required by
subsection (a)(2) or (b)(1)(A)—
‘‘(A) shall be assessed and collected in the
same manner as if it were a tax imposed by
subtitle C, and
120
‘‘(B) shall be paid on or before the return
due date for the partnership taxable year in
which the partnership adjustment takes effect.
‘‘(2) INTEREST.—For purposes of determining
interest, any payment required by subsection (a)(2)
or (b)(1)(A) shall be treated as an underpayment
of tax.
‘‘(3) PENALTIES.—
‘‘(A) IN
GENERAL.—In the case of any
failure by any partnership to pay on the date
prescribed therefor any amount required by
subsection (a)(2) or (b)(1)(A), there is hereby
imposed on such partnership a penalty of 10
percent of the underpayment. For purposes of
the 
preceding 
sentence, 
the 
term
‘underpayment’ means the excess of any pay-
ment required under this section over the
amount (if any) paid on or before the date pre-
scribed therefor.
‘‘(B) ACCURACY-RELATED
AND
FRAUD
PENALTIES MADE APPLICABLE.—For purposes
of part II of subchapter A of chapter 68, any
payment required by subsection (a)(2) shall be
