Opinion of the Court by
announced by
The problem of the federal income tax consequences of intra-family assignments of income is brought into focus again by this case.
The stipulated facts concern the taxable years 1937 to 1941, inclusive, and may be summarized as follows:
The respondent taxpayer was an inventor-patentee and the president of the Sunnen Products Company, a corporation engaged in the manufacture and sale of patented grinding machines and other tools. He held 89% or 1,780 out of a total of 2,000 shares of the outstanding stock of the corporation. His wife held 200 shares, the vice-president held 18 shares and two others connected with the corporatiоn held one share each. The corporation’s board of directors consisted of five members, including the taxpayer and his wife. This board was elected annually by the stockholders. A vote-of three directors was required to take binding action.
The taxpayer had entered into several non-exclusive agreements whereby the corporation was licensed to manufacture and sell various devices on which he had applied *594 for patents. 1 In return, the corporation agreed to pay to the taxpayer a royalty equal to 10% of the gross sales price of the devices. These agreements did not require the corporation to manufacture and sell any particular number of devices; nor did they specify a minimum amount of royalties. Each party had the right to cancel the licenses, without liability, by giving the other party written notice of either six months or a year. 2 In the absence of cancellation, the agreements were to continue in force for ten years. The board of directors authorized the corporation to execute each of these contracts. No notices of cancellation were given. Two of the agreements were in effect throughout the taxable years 1937- *595 1941, while the other two were in existence at all pertinent times after June 20,1939.
The taxpayer at various times assigned to his wife all his right, title and interest in the various license contracts. 3 She Was given exclusive title and power over the royalties accruing under these contracts. All the assignments were without consideration and were made as gifts to the wife, those occurring after 1932 being reported by the taxpayer for gift tax purposes. The corporation was notified of each assignment.
In 1937 the corporation, pursuant to this arrangement, paid the wife royalties in the amount of $4,881.35 on the license contract made in 1928; no other royalties on that contract were paid during the taxable years in question. The wife received royalties from other contracts totaling $15,518.68 in 1937, $17,318.80 in 1938, $25,243.77 in 1939, $50,492.50 in 1940, and $149,002.78 in 1941. She included all these payments in her income tax returns for those years, and the taxes she paid thereon have not been refunded.

Relying upon its own prior decision in
Estate of Dodson
v.
Commissioner,
The Tax Court’s decision was affirmed in part and reversed in part by the Eighth Circuit Court of Appeals.
If the doctrine of res judicata is properly applicable so that all the royalty payments made during 1937-1941 are governed by the prior decision of the Board of Tax Appeals, the case may be disposed of without reaching the merits of the controversy. We accordingly cast our attention initially on that possibility, one that has been explored by the Tax Court and that has been fully argued by the parties before us.
It is first necessary to understand something of the recognized meaning and scope of
res judicata,
a doctrine judicial in origin. The general rule of
res judicata
applies to repetitious suits involving the same cause of action. It rests upon considerations of economy of judicial time and public policy favoring the establishment of certainty in legal relations. The rule provides that 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 аny other admissible matter which might have been offered for that purpose.”
Cromwell
v.
County of Sac,
But where the second action between the same parties is upon a different cause or demand, the principle of
*598
res judicata
is applied much more narrowly. In this situation, the judgment in the prior action operates as an estoppel, not as to matters which might have been litigated and determined, but “only as to those matters in issue or points controverted, upon the determination of which the finding or verdict was rendered.”
Cromwell
v.
County of Sac, supra,
353. And see
Russell
v.
Place,
These same concepts are applicable in the federal income tax field. Income taxes are levied on an annual basis. Each year is the origin of a new liability and of a separate cause of action. Thus if a claim of liability or non-liability relating to a particular tax year is litigated, a judgment on the merits is
res judicata
as to any subsequent proceeding involving the same claim and the same tax year. But if the later proceeding is concerned with a similar or unlike claim relating to a diffеrent tax year, the prior judgment acts as a collateral estoppel only as to those matters in the second proceeding which were actually presented and determined in the first suit. Col
*599
lateral estoppel operates, in other words, to relieve the government and the taxpayer of “redundant litigation of the identical question of the statute’s application to the taxpayer’s status.”
Tail
v.
Western Md. R. Co.,
But collateral estoppel is a doctrine capable of being applied so as to avoid an undue disparity in the impact of income tax liability. A taxpayer may secure a judicial determination of a particular tax matter, a matter which may recur without substantial variation for some years thereafter. But a subsequent modification of the significant facts or a change or development in the controlling legal principles may make that determination obsolete or erroneous, at least for future purposes. If such a determination is then perpetuated each succeeding year as to the taxpayer involved in the original litigation, he is accorded a tax treatment different from that given to other taxpayers of the same class. As a result, there are inequalities in the administration of the revenue laws, discriminatory distinctions in tax liability, and a fertile basis for litigious confusion. Compare
United States
v.
Stone & Downer Co.,
And so where two cases involve income taxes in different taxable years, collateral estoppel must be used with its limitations carefully in mind so as to аvoid injustice. It must be confined to situations where the matter raised in the second suit is identical in all respects with that
*600
decided in the first proceeding and where the controlling facts and applicable legal rules remain unchanged.
Tait
v.
Western Md. R. Co., supra.
If the legal matters determined in the earlier case differ from those raised in the second case, collateral estoppel has no bearing on the situation. See
Travelers Ins. Co.
v.
Commissioner,
Of course, where a question of fact essential to the judgment is actually litigated and determined in the first tax proceeding, the parties are bound by that determination in a subsequent proceeding even though the cause of action is different. See
The Evergreens
v.
Nunan,
It is readily apparent in this case that the royalty payments growing out of the license cоntracts which were not involved in the earlier action before the Board of Tax Appeals and which concerned different tax years are free from the effects of the collateral estoppel doctrine. That is true even though those contracts are identical in all important respects with the 1928 contract, the only one that was before the Board, and even though the issue as to those contracts is the same as that raised by the 1928 contract. For income tax purposes, what is decided as to one contract is not conclusive as to any other contract which is not then in issue, however similar or identical it may bе. In this respect, the instant case thus differs vitally from Tait v. Western Md. R. Co., supra, where the two proceedings involved the same instruments and the same surrounding facts.
A more difficult problem is posed as to the $4,881.35 in royalties paid to the taxpayer’s wife in 1937 under the 1928 contract. Here there is complete identity of facts, issues and parties as between the earlier Board proceeding and the instant one. The Commissioner claims, however, that legal principles developed in various intervening decisions of this Court have made plain the error of the Board’s conclusion in the earlier proceeding, thus creating a situation like that involved in
Blair
v.
Commissioner, supra.
This change in the legal picture is said tо have been brought about by such cases as
Helvering
v.
*603
Clifford,
Had the taxpayer retained the various license contracts and assigned to his wife the right to receive the royalty
*604
payments accruing thereunder, such payments would clearly have been taxable income to him. It has long been established that the mere assignment of the right to reсeive income is not enough to insulate the assignor from income tax liability.
Lucas
v.
Earl,
It is the taxpayer’s contention that the license contracts rather than the patents and the patent applications were the ultimate source of the royalty payments and constituted income-producing property, the assignment of which freed the taxpayer from further income tax liability. We deem it unnecessary, however, to meet that contention in this case. It is not enough to trace income to the property which is its true source, a matter which may become more metaphysical than legal. Nor is the tax problem with which we are concerned necessarily answered by the fact that such property, if it can be properly identified, has been assigned. The crucial question remains whether the assignor retains sufficient power and control over the assigned property or over receipt of the income to make it reasonable to treat him as the recipient of the income for tax purposes. As was said in
Corliss
v.
Bowers,
It is in the realm of intra-family assignments and transfers that the
Clifford-Horst
line of cases has peculiar applicability. While specifically relating to short-term family trusts, the
Clifford
case makes clear that where the parties to a transfer are members of the same family group, special scrutiny is necessary “lest what is in reality but one economic unit be multiplied into two or more by devices which, though valid under state law, are not conclusive so far as § 22 (a) is cоncerned.”
In
Harrison
v.
Schaffner, supra,
682, it was again emphasized that “one vested with the right to receive income did not escape the tax by any kind of anticipatory arrangement, however skillfully devised, by which he procures payment of it to another, since, by the exercise of his power to command the income, he enjoys the benefit of the income on which the tax is laid.” And it was also noted that “Even though the gift of income be in form accomplished by the temporary disposition of the donor’s property which produces the income, the donor retaining every other substantial interest in it, we have not allowed the form to obscure the reality.”
The principles which have thus been recognized and developed by the Clifford and Horst cases, and those following them, are directly applicable to the transfer of patent license contracts between members of the same family. They are guideposts for those who seek to determine in a particular instance whether such an assignor retains sufficient control over the assigned contracts or over the receiрt of income by the assignee to make it fair to impose income tax liability on him.
Moreover, the clarification and growth of these principles through the Clifford-Horst line of cases constitute, in our opinion, a sufficient change in the legal climate to render inapplicable, in the instant proceeding, the doctrine of collateral estoppel relative to the assignment of *607 the 1928 contract. True, these cases did not originate the concept that an assignor is taxable if he retains control over the assigned property or power to defeat the receipt of income by the assignee. But they gave much added emphasis and substance to that concept, making it more suited to meet the “attenuated subtleties” created by taxpayers. So substantial was the amplification of this concept as to justify a reconsideration of earlier Tax Court decisions reached without the benefit of the expanded notions, decisions which are now sought to be perpetuated regardless of their present correctness. Thus in the earlier litigation in 1935, the Board of Tax Appeals was unable to bring to bear on the assignment of the 1928 contract the full breadth of the ideas enunciated in the Clifford-Horst series of cases. And, as we shall see, a proper application оf the principles as there developed might well have produced a different result, such as was reached by the Tax Court in this case in regard to the assignments of the other contracts. Under those circumstances collateral estoppel should not have been used by the Tax Court in the instant proceeding to perpetuate the 1935 viewpoint of the assignment.
The initial determination of whether the assignment of the various contracts rendered the taxpayer immune from income tax liability was one to be made by the Tax Court. That is the agency designated by law ta find and examine the facts and to draw conclusions as to whether a particulаr assignment left the assignor with substantial control over the assigned property or the income which accrues to the assignee. And it is well established that its decision is to be respected on appeal if firmly grounded in the evidence and if consistent with the law.
Commissioner
v.
Scottish American Co.,
The facts relative to the assignments of the contracts are undisputed. As to the legal foundation of the Tax Court’s judgment on the tax consequences of the assignments, we are unable to say that its inferences and conclusions from those facts are unreasonable in the light of the pertinent statutory or administrative provisions or that they are inconsistent with any of the principles enunciated in the Clifford-Horst line of cases. Indeed, due regard for those principles leads one inescapably to the Tax Court’s result. The taxpayer’s purported assignment to his wife of the various license contracts may properly be said to have left him with something more than a memory. He retained very substantial interests in the contracts themselves, as well as power to control the payment of royalties to his wife, thereby satisfying the various criteria of taxability set forth in the Cliff ord-Horst group of cases. That fact is demonstrated by the following considerations :
(1) As president, director and owner of 89% of the stock of the corporation, the taxpayer remained in a position to exercise extensive control over the license contracts after assigning them to his wife. The contracts all provided that either party might cancel without liability upon giving the required notice. This gave the taxpayer, in his dominant position in the corporation, power to procure the cancellation of the contracts in their entirety. That power was nonetheless substantial because the taxpayer had but one of the three directors’ votes necessary to sanction such action by thе corporation. Should a majority of the directors prove unamenable to his desires, the frustration would last no longer than the date of the next annual election of directors by the stockholders, an election which the taxpayer could control by *609 reason of his extensive stock holdings. The wife, as as-signee and as a party to contracts expressly terminable by the corporation without liability, could not prevent cancellation provided that the necessary notice was given.
And it is not necessary to assume that such cancellation would amount to a fraud on the corporation, a fraud which could be enjoined or otherwise prevented. Cancellation conceivably could occur because the taxpayer and his corporation were ready to make new license contracts on terms more favorable to the corporation, in which case no fraud would necessarily be present. All that we are concerned with here is the power to procure cancellation, not with the possibility that such power might be abused. And once it is evident that such power exists, the conclusion is unavoidable that the taxpayer retained a substantial interest in the license contracts which he assigned.
(2) The taxpayer’s controlling position in the corporation also permitted him to regulate the amount of royalties payable to his wife. The contracts specified no minimum royalties and did not bind the corporation to manufacture and sell any particular number of devices. Hence, by controlling the production and sales policies of the corporation, the taxpayer was able to increase or lower the royalties; or he could stop those royalties completely by eliminating the manufacture of the devices covered by the royalties without cancelling the contracts.
(3) The taxpayer remained the owner of the patents and the patent applications. Since the licenses which he gave the corporation were non-exclusive in nature, there was nothing to prevent him from licensing other firms to exploit his patents, thereby diverting some or all of the royalties from his wife.
(4) There is absent any indication that the transfer of the contracts effected any substantial change in the tax *610 payer’s economic status. Despite the assignments, the license contracts and the royalty payments accruing thereunder remained within the taxpayer’s intimate family group. He was able to enjoy, at least indirectly, the benefits received by his wife. And when that fact is added to the legal controls which he retained over the contracts and the royalties, it can fairly be said that the taxpayer retained the substance of all the rights which he had prior to the assignments. See Helvering v. Clifford, supra, 335-336.
These factors make reasonable the Tax Court’s conclusion that the assignments of the license contracts merely involved a transfer of the right to receive income rather than a complete disposition of all the taxpayer’s interest in the contracts and the royalties. The existence of the taxpayer’s power to terminate those contracts and to regulate the amount of the royalties rendered ineffective for tax purposes his аttempt to dispose of the contracts and royalties. The transactions were simply a reallocation of income within the family group, a reallocation which did not shift the incidence of income tax liability.
The judgment below must therefore be reversed and the case remanded for such further proceedings as may be necessary in light of this opinion.
Reversed.
Notes
The various devices involved were as follows:
(1) A cylinder grinder. The taxpayer applied for a patent on Nov. 17, 1927, and was issued one on Dec. 4, 1934. The royalty agreement to mаnufacture and sell this device was dated Jan. 10, 1928. This agreement expired on Jan. 10,1938; a renewal agreement in substantially the same terms was then executed for the balance of the life of the patent, which ends on Dec. 4,1951.
(2) A pinhole grinder. The taxpayer applied for a patent on Dec. 4, 1931, and was issued one on June 13, 1933. The royalty agreement to manufacture and sell this device was dated Dec. 5, 1931.
(3) A crankshaft grinder. The taxpayer applied for a patent on May 22, 1939, and was issued one on May 6, 1941. The royalty agreement to manufacture and sell this device was dated June 20, 1939.
(4) Another crankshaft grinder. The taxpayer applied for a patent on Dec. 29, 1939. He assigned this application to his wife on Dec. 29, 1942, and she was issued a patent on Jan. 26, 1943. The royalty agreement to manufacture and sell this device was dated June 20,1939.
The taxpayer remained the owner of the first three patents throughout the year 1941, and he remained the owner of the patent application on the fourth device throughout that year.
Six months’ notice was provided in the agreement dated Jan. 10, 1928, covering the cylinder grinder. The other three agreements provided for one year’s notice of cancellation.
On Jan. 8, 1929, the taxpayer assigned to his wife “all my rights title and interest in and to the Royalty which shall accrue hereаfter to me” upon the royalty contract of Jan. 10, 1928, with respect to the cylinder grinder device. Since the Commissioner of Internal Revenue raised some question as to the sufficiency and completeness of this assignment, the taxpayer executed a further assignment on Dec. 21, 1931. This second assignment confirmed the first one and stated further that his wife was assigned “all of my right, title and interest in and to said royalty contract of January 10, 1928 .... And I hereby state that the royalties accruing under said royalty contract have heretofore been and are hereafter the sole and exclusive property of the said Cornelia Sunnen [his wife], and hereby declare that said rоyalties shall be paid to the said Cornelia Sunnen or to her order, and that she shall have the sole right to collect, receive, receipt for, retain or sue for said royalties.”
Assignments similar in form and substance to the assignment of Dec. 21,1931, were made as to the other three royalty contracts.
In the Dodson case, Dodson owned 51% of the stock of a corporation and his wife owned the other 49%. He was the owner of a formula and trade mark. Pursuant to a contract which he made with the corporation, the corporation was given the exclusive use of the formula and trade mark for 5 years, renewable for a like period. Dodson was to receive in return a royalty measured by a certain percentage of the net sales. He then assigned a one-half interest in the contract to his wife, retaining his full interest in the formula and trade mark. The Tax Court held that his dominant stock position permitted him to cancel or modify the contract at any time, thus rendering him taxable on the income flowing from his wife’s share in the contract.

The pertinent statutory provisions are of little help to the matter in issue. Section 22 (a) of the Revenue Act of 1936, 49 Stat. 1648, and § 22 (a) of the Revenue Act of 1938, 52 Stat. 447, cover the taxable years in question. Those sections, which are identical with the current § 22 (a) of the Internal Revenue Codе, define “gross income” to include “gains, profits, and income derived from salaries, wages, or compensation for personal service, of whatever kind and in whatever form paid, or from professions, vocations, trades, businesses, commerce, or sales, or dealings in property, whether real or personal, growing out of the ownership or use of or interest in such property; also from interest, rent, dividends, securities, or the trans *604 action of any business carried on for gain or profit, or gains or profits and income derived from any source whatever.” See also Art. 22 (a) — 1 of Treasury Regulations 94, promulgated under the 1936 Act; Art. 22 (a)-l of Treasury Regulations 101, promulgated under the 1938 Act; and § 19.22 (a) — 1 of Treasury Regulations 103, promulgated under the Internal Revenue Code.
