delivered the opinion of the Court.
Respondent, a Missouri corporation, owns a leasehold of a plot of ground together with an office building erected on it. In 1942 the Commissioner assessed deficiencies against respondent for the taxable years 1933, 1938, and 1939, determining that it had claimed an excessive value as its basis for depreciating the property. These deficiencies were predicated on a basis of $385,000 amortized over the life of the lease. Respondent, who claimed a base of $860,000 amortized over a shorter period, filed petitions for review with the Tax Court. Meanwhile respondent filed a petition under ch. X of the Bankruptcy Act which ended in a confirmed plan of reorganization. Although the Collector filed proof of claim for the deficiencies in those proceedings, he later withdrew the claim under a stipulation that the withdrawal was "without prejudice” and did not constitute a determination of or prejudice the rights of the United States to any taxes with respect to any year other than those involved in the claim. Shortly thereafter respondent and the Commissioner filed stipulations in the pending Tax Court proceedings stating that "there is no deficiency in Federal income tax due” from respondent for the taxable years in question, that the tax liability for each of the years was nil, and that the jeopardy assess

ment was abated.
*
The Tax Court, pursuant to the stipulation, entered formal decisions that there were no deficiencies for the taxable years in question. The Tax Court, however, held no hearing; no stipulations of fact were entered into; no briefs were filed or argument had. The issue as to the correctness of the basis of depreciation used by respondent was, however, the basis of its appeal to the Tax Court. And so, when the Commissioner in 1948 ■ assessed deficiencies for the years 1943, 1944, and 1945, challenging once more the correctness of the basis of depreciation, respondent paid the deficiencies and brought this suit to recover, alleging
inter alia
that the decisions of the Tax Court for the years 1933, 1938, and 1939 were
res judicata
of the fact that the basis for depreciation was $860,000. The District Court held against respondent.
The governing principle is stated in
Cromwell
v.
County of Sac,
“But where the second action between the same parties is upon a different claim or demand, the *505 judgment in the prior action operates as an estoppel only as to those matters in issue or points controverted, upon the determination of which the finding or verdict was rendered. In all cases, therefore, where it is sought to apply the estoppel of a judgment rendered upon one cause of action to matters arising in a suit upon a different cause of action, the inquiry must always be as to the point or question actually litigated and determined in the original action, not what might have been thus litigated and determined. Only upon such matters is the judgment conclusive in another action.”
And see
Tait
v.
Western Md. R. Co.,
We conclude that the decisions entered by the Tax Court for the years 1933, 1938, and 1939 were only a
pro forma
acceptance by the Tax Court of an agreement between the parties to settle their controversy for reasons undisclosed. There is no showing either in the record or by extrinsic evidence (see
Russell
v.
Place,
Reversed.
Notes
The stipulation for the year 1933, which is typical, reads as follows:
“It is hereby stipulated that there is no deficiency in Federal income tax due from the petitioner for the taxable year 1933 and that the following statement shows the petitioner’s Federal income tax liability for the taxable year 1933:
“Tax liability. None
“Assessment (Jeopardy):
“January 23, 1942 (not paid). $2,188.12
“Assessment to be abated. $2,188.12”
