NEWMAN, Circuit Judge.
The appellants are nineteen individual taxpayers who were partners of the Denver-based Dillon Oil Technology Partnership in tax years 1983 and 1984. In 2003, after over a decade of litigation, the IRS assessed penalties in accordance with now repealed I.R.C. § 6621(c), which penalizes “substantial” underpayments of tax “attributable to tax motivated transactions” (“TMTs”). The appellants paid the tax and penalties in 2004, and, in 2006, initiated a refund suit in the United States Court of Federal Claims. The court dismissed the appellants’ suit for lack of subject matter jurisdiction under the Tax Equity and Fiscal Responsibility Act (“TEFRA”),
I.R.C. § 7422(h), which provides that individual partners may not bring tax challenges relating to subject matter “attributable to a partnership item.” Rather, such claims must be brought in a partnership-level suit by the partnership representative or Tax Matters Partner (“TMP”). On this ground, we affirm the dismissal. The appellants’ claim is an impermissible collateral attack.
BACKGROUND
In tax years 1983 and 1984, the Dillon Oil partnership reported significant losses on its oil and gas technology investments. These losses were passed through to the partners including appellants, who claimed the losses as deductions on their personal income tax returns.
In 1987 and 1988, the IRS determined, with respect to the partnership tax returns, that most of the Dillon Oil losses claimed in 1983 and 1984 were not deductible, and issued Final Partnership Administrative Adjustments (“FPAAs”) stating several reasons for its decision, including:
(a) It has not been established that the underlying events, transactions and expenditures occurred in fact or in substance;
(b) It has not been established that the claimed deductions originated in a trade or business or in a transaction entered into for profit;
(e) It has not been established that the notes executed by the partners in favor of the partnership are not non-recourse, are not contingent, are not speculative and have economic substance;
In the event the transactions are substantiated as to amount and nature of the item and it is held that the transactions have economic-substance, it is determined that the partners are not at risk within the meaning of Internal Revenue Code Section 465 for any amounts in excess of those actually paid in cash to the partnership, and thus said losses are in excess of the partners adjusted basis.

1983 FPAA ¶ 1, J.A. 67-68;
see also
1984 FPAA ¶ 1, J.A. 162-63 (stating similar reasons).
The IRS also sent FPAAs to other similarly situated Denver-based partnerships. Dillon Oil, along with these partnerships,
filed consolidated Tax Court suits for each tax year under the caption
Vulcan Oil Technology Partners v. Commissioner.
The petitions alleged a number of errors by the IRS, including that “the Commissioner has erroneously proposed an addition to tax under Code Section 6621(c), ...” Tax Court Petition ¶ 4(B), No. 21530-87 (July 2, 1987);

Dillon Oil’s Tax Court cases were stayed pending resolution of
Krause v. Commissioner,
a test case for over 2,000 related cases.
Krause
involved oil and gas transactions, primarily trades in debt obligations and license fees, claimed as losses on partners’ tax returns. After a fifteen week trial, the
Krause
court found that these transactions lacked “profit objective” as required of deductible losses under I.R.C. § 183, and disallowed the losses.
Krause v. C.I.R.,
99 T.C. 132, 176 (1992). The court also affirmed the IRS’s imposition of TMT penalty interest under § 6621(c) based on the transactions, stating that
By regulation, among the types of transactions that are considered to be tax-motivated transactions within the meaning of section 6621(c) are those with respect to which the related tax deductions are disallowed under section 183 for lack of profit objective. In light of our findings as to the lack of profit objective, petitioners are liable for increased interest under section 6621(c).

The
Krause
decision had a predictable effect on the
Vulcan Oil
suits. In 1998, several
Vulcan Oil
partnerships moved the Tax Court to require the IRS to settle on
pre-Krause
terms.
See Vulcan Oil Tech. Partners v. C.I.R.,
110 T.C. 153 (1998). The terms the partnerships sought would have permitted tax deductions
for the amount of cash that investors had invested in the [ ] tax shelters and no additions to tax or penalties ... other than increased interest under section 6621(c) or its predecessor section 6621(d).
Id.

Id.
at 164. The Tax Court held that the partners who had not settled their cases with the IRS prior to the decision in Krause “were to be bound by the opinion in

Vulcan Oil
suits for lack of prosecution. The motions stated that the IRS would make adjustments to Dillon Oil’s FPAA in accordance with
Krause.
The Tax Court sent Orders to Show Cause to the Dillon Oil partners, asking “why this case should not be dismissed for failure properly to prosecute and that there are adjustments to partnership items [consistent with
Krause].”
Show Cause Order 2. The Dillon Oil partners did not respond, and on June 13, 2002, the
Vulcan Oil
suits were dismissed.

Following the
Vulcan Oil
dismissal, the IRS sent Form 4549A to the Dillon Oil partners.
The Form stated that the part
ners would be assessed enhanced penalty interest under I.R.C. § 6621(c) for tax years 1983 and 1984. It identified the amount of underpayment subject to TMT penalty interest, and stated that TMT penalty interest would be assessed at “120%”.
Appellants paid the penalty interest in 2004, with the last payment made no later than October 18, 2004.

Appellants paid the penalty interest in 2004, with the last payment made no later than October 18, 2004.
On April 5, 2006, the appellants initiated this lawsuit in the Court of Federal Claims. The complaint alleged that
Krause
“was wrong as a matter of law,” and that the Dillon Oil partners “are not bound by [its] outcome.” Compl. ¶¶ 21(j), 32(j). The government moved to dismiss for lack of jurisdiction, citing this court’s decisions in
Keener v. United States,
551 F.3d 1358 (Fed.Cir.2009), and
Prati v. United States,
603 F.3d 1301 (Fed.Cir.2010). The government also stated that “the substantive question of whether the Dillon Oil partnership entered into a tax-motivated transaction has already been answered” in the
Vulcan Oil
suit. Gov’t Mot. to Dismiss 12, ECF No. 28. The appellants countered that because
Krause
was wrongly decided, “no TMT determinations were ever made.” Taxpayers’ Opp. 4, 15-16, ECF No. 37. The appellants argued that in
Keener,
this court stated that dismissal is not proper “‘when no partnership-level determination has been made that the transactions were tax motivated.’ ”
Id.
3-4 (quoting 551 F.3d at 1367).
The Court of Federal Claims granted the government’s motion to dismiss, explaining that “it is clear that the
Vulcan Oil
court understood that the Dillon Oil partnership would be bound by the
Krause
decision, including the imposition of TMT penalties under § 183.” 101 Fed.Cl. 791, 797 n. 9. The court further explained that
The
Vulcan Oil
court had previously held that
Krause
would apply to non-settling partners like the plaintiffs. The Dillon Oil partnership TMP had an opportunity to challenge those calculations at the partnership level by objecting to the show cause order, but elected not to object. At its core, the plaintiffs’ objection is to the IRS’s and
Vulcan Oil
court’s application of
Krause
to the Dillon Oil partnership, a partnership-level issue.
... The plaintiffs’ arguments regarding the
Krause
decision and the
Krause
court’s misapplication of § 183 plainly would require this court to examine the Dillon Oil partnership transactions to determine if the transactions identified in the modified calculations are not covered by § 183.
Id.
at 798. The appellants timely appealed.
Discussion
A dismissal for lack of subject matter jurisdiction is a ruling of law, and receives plenary determination.
Ferreiro v. United States,
350 F.3d 1318, 1324 (Fed.Cir.2003). As the party seeking the exercise of jurisdiction, the appellants have the
burden of establishing that jurisdiction exists.
Keener,
551 F.3d at 1361.
TEFRA statute I.R.C. § 7422(h) bars partner-level suits “attributable to partnership items ... except as provided in section 6228(b) or section 6230(c).”
See also Schell v. United States,
589 F.3d 1378, 1382 (Fed.Cir.2009) (“TEFRA limits a partner’s ability to seek a refund based on adjustments made to the partnership’s return by depriving all courts of jurisdiction to hear partner refund claims where the refund is ‘attributable to partnership items’ ”).
Under TEFRA, the term “ ‘partnership item’ generally encompasses items ‘required to be taken into account for the partnership’s taxable year,’ and those ‘more appropriately determined at the partnership level than at the partner level.’ ”
Schell,
589 F.3d at 1381 (quoting I.R.C. § 6231(a)(3)). A tax item is “attributable to” a partnership item if it is “due to, caused by, or generated by” a partnership item.
Keener,
551 F.3d at 1365. A “nonpartnership item” is “an item which is (or is treated as) not a partnership item.” I.R.C. § 6231(a)(4). “The tax treatment of nonpartnership items requires partner-specific determinations that must be made at the individual partner level.”
Duffie v. United States,
600 F.3d 362, 366 (5th Cir.2010). In certain instances, partnership items “cease to be partnership items” and become nonpartnership items, such as when the Secretary provides notice to a partner that an item shall be treated as a nonpartnership item, or when the Secretary enters into a settlement agreement with the partner with respect to such items. I.R.C. § 6231(b).
I.
Appellants state that although Dillon Oil and its partners were bound by the opinion in
Krause,
the IRS had no authority to impose TMT penalty interest following
Vulcan Oil
because “no partnership-level TMT was ever made” in
Krause.
Appellants’ Br. 28. Appellants state that they “do not seek to relitigate
Krause,”
because
Krause
was a “non-TMT determination” and they had no reason to appeal it. Reply Br. 3. For support, appellants rely on
Copeland v. Commissioner,
290 F.3d 326 (5th Cir.2002), wherein the Fifth Circuit held that
Krause
erred in imposing § 6621(c) penalty interest “under § 183.”
Id.
The government states that “[s]ince both the FPAAs and
Krause
determined that the transactions in issue were tax-motivated, the effect of the dismissal of Dillon Oil’s petition [in
Vulcan Oil
] was to make final the determination that the partnership transactions were tax-motivated.” Gov’t Br. 11. According to the government, this case is not materially different from this court’s dismissals in
Keener
and
Prati,
because there is no meaningful difference between dismissal for failure to prosecute as compared to a settlement between the IRS and an individual partner, such as in
Prati,
603 F.3d at 1308, and
Keener,
551 F.3d at 1360. Gov’t Br. 14. We address the parties’ various arguments in turn.
II.
The appellants’ representation that they are not attempting to relitigate
Krause
is not accurate. The Court of Federal Claims correctly noted that the appellants’ complaint in this ease specifically stated that
Krause
“was wrong as a matter of law.”
Bush,
101 Fed.Cl. at 794 n. 6. Moreover, despite the appellants’ attempts to recharacterize
Krause
as a “non-TMT determination,” it is inescapable that “[t]he
Krause
Court ... expressly imposed enhanced interest under § 6621(c)” as the Court of Federal Claims found.
Id.
at 794 (citing
Krause,
99 T.C. at 180).
The question that remains is whether the appellants were bound by all of
Krause,
including its conclusion that “petitioners are liable for increased interest under section 6621(c),” or whether the appellants can potentially escape the
Krause
TMT finding if it was incorrectly decided. The Court of Federal Claims held that
Krause
was binding in all respects, “including the imposition of TMT penalties under § 183,” and that plaintiffs’ arguments regarding the
Krause
decision would require re-examination of Dillon Oil partnership transactions “to determine if the transactions identified in the modified calculations are not covered by § 183.” 101 Fed.Cl. at 798.
We agree with the Court of Federal Claims. The
Vulcan Oil
court held that Dillon Oil was bound by “the opinion” in Krause—not merely a portion of the opinion as now interpreted by the appellants. The appellants’ opportunity to challenge
Krause
passed when
Vulcan Oil
was dismissed. “When a court of competent jurisdiction has entered a final judgment on the merits of a cause of action, the parties to the suit and their privies are thereafter bound not only as to every matter which was offered and received to sustain or defeat the claim or demand, but as to any other admissible matter which might have been offered for that purpose.”
C.I.R. v. Sunnen,
333 U.S. 591, 597, 68 S.Ct. 715, 92 L.Ed. 898 (1948). This rule applies “even if obtained upon a default.”
Riehle v. Margolies,
279 U.S. 218, 225, 49 S.Ct. 310, 73 L.Ed. 669 (1929).
Copeland
is of no assistance to appellants. In
Copeland,
the taxpayers stipulated that
Krause
generally “controlled,” but specifically carved out an exception for “the conclusion that I.R.C. § 6621(c) applies” and adjudicated that issue separately. 290 F.3d at 328-29. The taxpayers then litigated § 6621(c) to the Court of Appeals for the Fifth Circuit without ever failing to prosecute or having their case dismissed.
See Copeland v. C.I.R.,
79 T.C.M. (CCH) 2127 (T.C.2000), aff'd in part, rev’d in part, 290 F.3d 326 (5th Cir.2002). Unlike the taxpayers in
Copeland,
the Dillon Oil partners did not challenge or appeal any aspect of the Krause decision in the then pending
Vulcan Oil
suit. When
Vulcan Oil
was dismissed, the TMT finding in
Krause
became binding on Dillon Oil at the partnership-level, just as the taxpayers in Copeland would have been bound had they not appealed.
Copeland
also serves to undermine the appellants’ argument that
Krause
was a “non-TMT determination.” If that were true, the taxpayers in
Copeland
would not have separately litigated the imposition of § 6621(c) penalty interest and appealed to the Fifth Circuit. The Copeland taxpayers knew
Krause
was a TMT determination and challenged it accordingly.
For these reasons, we agree with the Court of Federal Claims that in order to set aside the IRS’s imposition of TMT penalty interest, it would be necessary to relitigate the
Vulcan Oil
court’s decision to bind Dillon Oil to “the opinion of
Krause.”
101 Fed.Cl. at 798. That is a partnership level issue; it affects the entire partnership, and there are no “partner-specific determinations that must be made at the individual partner level.”
Duffie,
600 F.3d at 366. Simply put, the appellants’ claim is “ ‘more appropriately determined at the partnership level than at the partner level.’ ”
Schell,
589 F.3d at 1381 (quoting I.R.C. § 6231(a)(3)). TEFRA contemplates “one proceeding” for the adjudication of partnership adjustments.
AD Global Fund, LLC ex rel. N. Hills Holding, Inc. v. United States,
481 F.3d 1351, 1355 (Fed.Cir.2007).
III.
The Court of Federal Claims held that our decisions in
Keener
and
Prati
are not meaningfully distinguishable from the present case, and we agree.
In
Prati,
we held that a partner-level suit claiming a refund for § 6621(c) interest was barred by TEFRA § 7422(h) because it fundamentally sought to relitigate issues settled in a prior partnership-level suit. 603 F.3d at 1308. The
Prati
litigants argued—much like the appellants here—that they were not directly challenging whether their transactions were tax motivated; rather they claimed only to challenge the IRS’s
application
of Treasury Regulation § 301.6621-2T, A-5.
Id.
We concluded that this regulation-based argument was “disingenuous” because, if successful, it would “invalidate” the IRS’s FPAA determination that the partnership’s transactions were tax motivated— which was not a part of the settlement agreement.
Id.
In other words, we held that the IRS’s finding of a TMT could not be challenged at the partner-level based on the argument that the IRS misapplied a rule or statute following a partnership-level settlement that was silent on that issue.
Likewise, in
Keener,
we held that a partner-level suit seeking refund
of
§ 6621(c) penalty interest was barred under § 7422(h) because the IRS issued FPAAs stating that the partnership engaged in sham transactions, and the taxpayers entered into settlements which did not alter that finding. 551 F.3d at 1367. The taxpayers argued that no partnership-level determination was actually made because the settlement agreements were silent on the TMT issue, but we rejected that argument on the basis that the FPAAs characterized the partnership transactions as “a series of sham transactions,” wherein sham transactions are clearly TMTs under § 6621(c)(3)(A)(v).
Id.
Here, the Court of Federal Claims found
Prati
and
Keener
unavoidable on the basis that a challenge to a § 6621(c) penalty interest assessment is “inherently” a dispute over the proper characterization of the partnerships’ transactions, and barred by § 7422(h). 101 Fed.Cl. at 797 (citing
Prati,
603 F.3d at 1308).
To the extent that the Court of Federal Claims held that a challenge to the imposition of § 6621(c) penalty interest is
always
inherently a dispute over the proper characterization of the partnerships’ transactions, we disagree. In
Keener,
we explicitly declined to “decide whether § 7422(h) precludes jurisdiction over every claim for a refund of penalty interest imposed pursuant to § 6621(c).” 551 F.3d at 1366 n. 7. In
Prati
and
Keener,
the FPAAs stated that the taxpayers’ transactions were “shams,” and therefore TMTs by statute. If that were not the case, it may have been necessary to point to some other TMT determination to resolve the jurisdictional question.
In this case, the FPAAs did not use the term “sham” to characterize Dillon Oil’s transactions. The FPAAs stated that the
transactions lacked “profit-motive” and “economic substance,” and possibly lacked “risk within the meaning of Internal Revenue Code Section 465.” Thus, it was necessary for the Court of Federal Claims to point to a TMT determination other than the “sham” language of
Keener
and
Prati
The court did so in finding it “clear that the
Vulcan Oil
court understood that the Dillon Oil partnership would be bound by the
Krause
decision, including the imposition of TMT penalties under § 183.” 101 Fed.Cl. at 797 n. 9.
We decline to address, in the first instance, whether the Dillon Oil FPAAs support an independent TMT finding akin to the “sham” transactions of
Keener
and
Prati
Dillon Oil’s Tax Court petitions certainly suggest that such a finding might be found, since the petitions expressly stated that the Commissioner “erroneously proposed an addition to tax under Code Section 6621(c).” But we need not decide this issue because, unlike in
Keener
and
Prati
the appellants here were bound by the determination of
Krause
as incorporated into
Vulcan Oil.
On this record, it is irrelevant whether
Krause
was rightly or wrongly decided. Dillon Oil’s partners did not appeal the dismissal of their partnership-level suit in
Vulcan Oil.
Although appellants argue that “[t]here was no reason” to appeal the
Vulcan Oil
dismissal because “there was no deteirmination in that dismissal of a TMT,” we are not persuaded.
See
Oral Argument 11:00-11:18, available at http:// www.cafc.uscourts.gov/oral-argument-reeordings/all/bush.html. The
Krause
decision unambiguously imposed TMT penalty interest.
See
99 T.C. at 180 (“In light of our findings as to the lack of profit objective, petitioners are liable for increased interest under section 6621(c)”). Indeed, that specific portion of
Krause
was appealed in no fewer than three circuits.
Hildebrand,
28 F.3d 1024;
Hill v. C.I.R.,
204 F.3d 1214 (9th Cir.2000);
Copeland,
290 F.3d 326. It is' not reasonable to read
Krause
as a “non-TMT determination” as appellants urge.
IV.
To the extent the Court of Federal Claims stated that it does not have
jurisdiction
to determine whether “there was ever a finding supporting TMT penalty interest,” we conclude that the court misspoke. A court always has jurisdiction to determine whether it has jurisdiction.
See Reynolds v. Army & Air Force Exch. Serv.,
846 F.2d 746, 747 (Fed.Cir.1988) (“If a motion to dismiss for lack of subject matter jurisdiction [ ] challenges the truth of the jurisdictional facts alleged in the complaint, the district court may consider relevant evidence in order to resolve the factual dispute.”). The court itself stated that “in considering a motion to dismiss for lack of subject matter jurisdiction, a court may look beyond the pleadings and ‘inquire into jurisdictional facts’ to determine whether jurisdiction exists.” 101 Fed.Cl. at 796 (citing
Rocovich v. United States,
933 F.2d 991, 993 (Fed.Cir.1991)).
Here, the court made several findings relating to the jurisdictional question of whether a TMT determination was ever made. The court found that the appellants were bound by
Krause,
and found that
Krause
expressly imposed § 6621(c) penalty interest under § 183. Based on these findings, the court concluded that this case was not materially different from
Keener
and
Prati
and dismissed. 101 Fed.Cl. at 797-98 (“the present case involves a partnership-level determination one step removed from the determinations made in
Prati
and
Keener.
However, this difference does not alter the outcome.”). We affirm on these grounds.
Precedent does not, as the Court of Federal Claims stated, preclude the court from examining whether a TMT finding was made. To the contrary, in both
Keener
and
Prati,
this court relied on TMT findings of “sham” transactions in order to affirm the dismissal of partner-level suits under § 7422(h). Here, the relevant TMT finding was made in
Krause
and became binding on appellants through
Vulcan Oil,
as the Court of Federal Claims found.
Conclusion
The appellants’ refund claims were properly dismissed under § 7422(h). The appellants cannot collaterally attack
Krause
or
Vulcan Oil
at this stage.
AFFIRMED
