*50 In a decision which has become final, this Court determined that P had an overpayment of Federal income tax for the taxable year 1987, due to a foreign tax carryback from 1989. Prior to the application of the carryback, P had a deficiency for 1987. P filed a timely motion to redetermine interest under
*267 OPINION
TANNENWALD, JUDGE: On January 28, 1997, the Court entered a decision in the instant case, which became final within the meaning of *53
Petitioner is a corporation whose principal offices were in Kansas City, Missouri, at the time its petition was filed. The Court's decision, pursuant to the stipulation of the parties, determined that there were overpayments for each of the taxable years 1987 and 1988. According to the stipulation, the overpayment for 1987 was due to a foreign tax carryback from 1989. The amount of the carryback exceeded the amount of the deficiency (as shown in the*54 stipulation) computed without taking such foreign tax carryback into effect. Petitioner has paid the unreduced deficiency and the interest thereon. Respondent has refunded the 1987 overpayment resulting from the carryback, a portion of overpayment interest thereon, and a portion of previously assessed deficiency interest for that year.
*268 Petitioner's motion to redetermine interest alleges that respondent erred in computing interest on that portion of the previously existing deficiency that was satisfied by the application of the foreign tax carryback. Respondent computed interest on such deficiency during the period beginning with the due date for petitioner's 1987 tax return and ending with the due date of the 1989 return, March 15, 1990. It is petitioner's position that, in any event, interest on the deficiency should stop accruing as of December 31, 1989, the end of the taxable year in which the carryback arose. Petitioner's position on these issues is identical to that of the taxpayer in
Petitioner adopts an indecisive approach*55 to support its motion to withdraw. Thus, it does not directly seek to persuade us to decide that we do not have jurisdiction, apparently assuming that we would decide the issue unfavorably to petitioner, see
At the outset, we are constrained to observe that we cannot accept petitioner's invitation to leave open the question of our jurisdiction of its motion to redetermine interest under
We turn first to the scope of
(c) Jurisdiction Over Interest Determinations. --
(1) In general. -- Notwithstanding subsection (a), if, within 1 year after the date the decision of the Tax Court becomes final under subsection (a) in a case to which this subsection applies, the taxpayer files a motion in the Tax Court for a redetermination of the amount of interest involved, then the Tax Court may reopen the case solely to determine whether the taxpayer has made an overpayment of such interest or the Secretary has made an underpayment of such interest and the amount thereof.
(2) Cases to which this subsection applies. -- This subsection shall apply where --
(A)(i) an assessment has been made by the Secretary under
(ii) the taxpayer has paid the entire amount of the deficiency plus interest claimed by the Secretary, and
(B) the Tax Court finds under
(3) Special rules. -- If the Tax Court determines under this subsection*58 that the taxpayer has made an overpayment of interest or that the Secretary has made an underpayment of interest, then that determination shall be treated under
(1) an assessment has been made by the Secretary under
(2) the taxpayer has paid the entire amount of the deficiency plus interest claimed by the Secretary, and
(3) within 1 year after the date the decision of the Tax Court becomes final under subsection (a), the taxpayer files a petition in the Tax Court for a determination that the amount of interest claimed by the Secretary exceeds the amount of interest imposed by this title,
then*59 the Tax Court may reopen the case solely to determine whether the taxpayer has made an overpayment of such interest and the amount of any such overpayment. * * *
Specifically, petitioner argues that, since the decision in this case became final under
As indicated, the amendment has an effective date of August 5, 1997. Unlike some statutory amendments, the effective date is not tied to a specific event. 3 Although the decision in this case became final under
Aside from the effective date issue, we do not share petitioner's concern as to our jurisdiction because no deficiency was determined by this Court and assessed pursuant to
*271
(a) General Rule. -- If the taxpayer files a petition with the Tax Court, the entire amount redetermined as the deficiency by the decision of the Tax Court which has become final shall be assessed and shall be paid upon notice and demand * * *
It cannot be gainsaid that, on its face, our decision*61 herein did not determine a deficiency for 1987 and that consequently no deficiency as determined by the Court was assessed. In this narrow context, it can be argued that the literal language of
Having decided that we have jurisdiction over petitioner's*62 motion to redetermine interest, we turn to the question whether to grant or deny petitioner's motion to withdraw such motion. Respondent argues that, if our jurisdiction attaches, we must exercise that jurisdiction and cannot grant petitioner's motion to withdraw.
During the pendency of a case in this Court, our jurisdiction is exclusive and, with a few exceptions, another proceeding may not be commenced or, if already commenced, is stayed.
The question before us is the extent to which the foregoing *63 principles should apply to a motion to redetermine interest under
If the Secretary has mailed to the taxpayer a notice of deficiency under
We think it significant that Congress, in enacting
As stated above, the issues are the same as those involved in
Petitioner's*65 motion to withdraw its motion to redetermine interest and its motion for such redetermination will be denied.
An appropriate order will be entered.
