311 U.S. 189 (1940)
HELVERING, COMMISSIONER OF INTERNAL REVENUE,
v.
JANNEY ET UX.[*]
No. 36.
Supreme Court of United States.
Argued November 18, 1940.
Decided December 9, 1940.
CERTIORARI TO THE CIRCUIT COURT OF APPEALS FOR THE THIRD CIRCUIT.
Mr. Thomas E. Harris, with whom Attorney General Jackson, Assistant Attorney General Clark, and Messrs. Sewall Key, Maurice J. Mahoney, and Miss Helen R. *190 Carloss were on the brief, for the Commissioner of Internal Revenue.
Mr. Bernhard Knollenberg, with whom Mr. Harry J. Rudick was on the brief, for respondents in No. 36. Mr. Frederick Baum, with whom Mr. Frank E. Karelsen, Jr. was on the brief, for petitioners in No. 113.
MR. CHIEF JUSTICE HUGHES delivered the opinion of the Court.
These cases present the same question, that is, whether under the Revenue Act of 1934, in the case of a joint return by husband and wife, the capital losses of one spouse may be deducted from the capital gains of the other.
In Helvering v. Janney, the wife realized net gains from the sale of capital assets during 1934, and the husband realized net losses from the sale of capital assets during the same year. They filed a joint income tax return reporting the capital gain, which represented the difference between the wife's adjusted capital gains and the husband's adjusted capital losses. The Commissioner ruled that the husband's losses could not be applied to reduce the gains realized by his wife and accordingly determined a deficiency. The Board of Tax Appeals sustained the Commissioner (39 B.T.A. 240) but the Circuit Court of Appeals for the Third Circuit reversed. 108 F.2d 564.
In Gaines v. Helvering, the husband realized a net gain from the sale of capital assets during 1934, while his wife sustained a net loss from the sale of capital assets. They filed a joint return reporting a capital loss, which represented the difference between the husband's net capital gain and his wife's net capital loss. The Commissioner, as in the Janney case, decided against this adjustment and the Board of Tax Appeals affirmed. The Circuit *191 Court of Appeals for the Second Circuit affirmed the decision of the Board. 111 F.2d 144.
In view of the conflict between these decisions, we granted certiorari. No. 36, 310 U.S. 617; No. 113, October 14, 1940.
Section 51 (b) of the Revenue Act of 1934[1] with respect to the returns of husband and wife provided:
"(b) Husband and Wife.  If a husband and wife living together have an aggregate net income for the taxable year of $2,500 or over, or an aggregate gross income for such year of $5,000 or over 
"(1) Each shall make such a return, or
"(2) The income of each shall be included in a single joint return, in which case the tax shall be computed on the aggregate income."
The same provision in substance is found in the earlier Revenue Acts from that of 1921.[2]
The "aggregate income," to which paragraph 2 of § 51 (b) refers, is clearly the aggregate net income as it is the aggregate income on which "the tax is to be computed." In that view the deductions to which either spouse would be entitled would be taken in the case of a joint return, from the aggregate gross income.
That was the construction placed upon the provision for a joint return in the Revenue Act of 1918 by the Solicitor of Internal Revenue in an opinion rendered in *192 1921.[3] After considering the terms of the statute and the reasonable inference as to the intent of Congress, the Solicitor concluded:
"From the foregoing it follows that the proper construction of the Revenue Act of 1918 permits a husband and wife living together, at their option, to file separate returns or a single joint return. If a single joint return is filed it is treated as the return of a taxable unit and the net income disclosed by the return is subject to both normal and surtax as though the return were that of a single individual. In cases, therefore, in which the husband or wife has allowable deductions in excess of his or her gross income, such excess may, if joint return is filed, be deducted from the net income of the other for the purpose of computing both the normal and surtax."
The terms of the Revenue Act of 1921 made this view even clearer.[4] Treasury Regulations 62, Article 401, promulgated under the Revenue Act of 1921, apparently followed the same view. That article provided as to joint returns of husband and wife, 
"Where the income of each is included in a single joint return, the tax is computed on the aggregate income and all deductions and credits to which either is entitled shall be taken from such aggregate income."[5]
*193 The question as to deductions for losses on sales or exchanges of securities arose under § 23 (r) (1) of the Revenue Act of 1932.[6] That provided that losses as there described should be allowed only to the extent of gains derived from such sales or exchanges. Nothing was said in this section which in any way affected the provision of the statute as to joint returns by husband and wife. The question in that relation, that is, as to deduction for losses on sales of securities, was submitted to the Commissioner of Internal Revenue and was answered by him on December 29, 1932, as follows:
"The specific question presented is whether the loss sustained by the husband may be applied to offset the same amount of gain realized by the wife in rendering joint income tax return for the year. In reply you are advised that, in the case of a husband and wife living together who file a joint income tax return, the tax liability is computed on the aggregate income as provided by section 51 (b) (2) of the Revenue Act of 1932, and such joint return is treated as if it was the return of a single individual. The aggregate income in such case would of course embrace the gains as well as the allowable deductions of each spouse. If it is correctly understood from your letter that the gains and losses in the illustration presented are from transactions falling within the same class within the meaning of the statute such as sales of securities not held for a period of more than two years, the loss sustained by the husband would offset the same amount of gain realized by the wife from such source."[7]
*194 This statement by the Commissioner applied the same principle which had previously been followed with respect to deductions in the joint returns of husband and wife, there having been no indication by Congress of any different purpose.
Treasury Regulations No. 77, promulgated under the Act of 1932, contained nothing to the contrary and the regulation theretofore obtaining as to such joint returns was left unchanged. Art. 381.
The Revenue Act of 1934 continued the prior statutory provisions as to joint returns of husband and wife, and § 117 (d) of that Act, as to capital losses, did not purport to alter the rule as to the right of the spouses to deductions in their joint return. Section 117 (d) merely limited the amount of losses which could be deducted, as follows:
"(d) Limitation on Capital Losses.  Losses from sales or exchanges of capital assets shall be allowed only to the extent of $2,000 plus the gains from such sales or exchanges."
The conclusion of the Commissioner with respect to the Act of 1932, in the opinion above mentioned, was equally applicable to the new Act.
It was not until 1935 that the Treasury Department by Article 117-5 of Regulations 86 undertook to provide that "the allowance of losses of one spouse from sales or exchanges of capital assets is in all cases to be computed without regard to gains and losses of the other spouse upon sales or exchanges of capital assets."[8]
We are of the opinion that under the provision of the Act of 1934 as to joint returns of husband and wife, which embodied a policy set forth in substantially the same terms for many years, Congress intended to provide *195 for a tax on the aggregate net income and that the losses of one spouse might be deducted from the gains of the other; and that this applied as well to deductions for capital losses as to other deductions. This, we think, was the meaning of the provision of the Revenue Act of 1934 when it was enacted, and it was subject to change only by Congress, and not by the Department.
In No. 36, the judgment of the Circuit Court of Appeals is affirmed.
In No. 113, the judgment of the Circuit Court of Appeals is reversed and the cause is remanded for further proceedings in conformity with this opinion.
No. 36, affirmed.
No. 113, reversed.
MR. JUSTICE ROBERTS took no part in the consideration and decision of this case.
