. delivered the opinion of the Court.
In computing its net taxable income for 1933 and 1934, respondent took a deduction of 3%% of the reserves it had set aside with respect to its combined policies of' life, health, and accident insurance. Section 203 (a) (2)
Legislative history discloses that a deduction similar to that allowed by § 203 (a) (2) first appeared in the Revenue Act of 1921,[5] and has reappeared in every revenue measure since, including that of 1939.[6] Prior to 1921, insurancé companies had not been allowed such a deduction, but had been subject to the same tax plan as corporations generally; the 1921 Act, however, wholly exempted insurance companies from the general scheme

2 The opinion is not officially reported; the Board relied on its earlier decisions in Equitable Life Assurance Society v. Commissioner, 33 B. T. A. 708 ; Monarch Life Ins. Co. v. Commissioner, 38 B. T. A. 716 ; and Pan-American Life Ins. Co. v. Commissioner, 38 B. T. A. 1430 .

As entirely new and separate tax provisions relating only to life insurance companies were thus enacted, it became necessary specifically to define what constituted a “life insurance company” within the meaning of the Act. Therefore, it was declared in the 1921 Act and all its successors that “when used in this title the term 'life insurance company’ means an-insurance company engaged in the business of issuing life insurance and annuity contracts (including contracts of combined life, health, and accident, insurance), the reserve funds of which held for the fulfillment of such contracts comprise more than 50 per centum of its total reserve funds.”[10]
7 The history of this legislation is set out in National Life Ins. Co. v. United States, 277 U. S. 508 , 523-524.

9 E. g., § 244 (a), Act of 1921, 42 Stat. 261 ; § 202 (a), Act of 1939, 53 Stat. 71 .
10 E. g., § 242, Act of 1921, 42 Stat. 261 ; § 201, Act of 1939, 53. Stat. 71. The government contends that the determinative ratio under this section is death reserves to total reserves; the insurance companies contend that the ratio is all reserves on the enumerated *270 types of policies to total reserves. Since ’ Oregon Mutual is admittedly a “life insurance company” regardless of which .of these contentions is correct, this question is not before us.

It is the Government’s contention that the change in the regulations was particularly appropriate because induced by judicial decision.[15] And it is true that this Court has held that reserves set aside by life insurance companies to protect payment of policy investment purchases cannot be used as the basis for deductions.[16] But those decisions rested upon the conclusion that the investment fund features had no relation to the insurance,, risks. Here, in the combined life and health and accident policies, the health and accident reserves are based upon contingencies of the commencement and continuance of disability. They have a direct and inseparable relationship to the very insurance contracts which bring respondent under a special tax scheme.[17] Nor is there a distinction, as petitioner urges, between that part of the reserve set aside to protect policy holders not yet disabled and that part set aside to protect those already disabled. The liability to those who have incurred disability is not a fixed sum, but remains a contingency, still uncertain in

14 In support of the Commissioner’s right to change the regulations under this supposed state of facts, the government cites Manhattan General Equipment Co. v. Commissioner, 297 U. S. 129 , 134-135, and Murphy Oil Co. v. Burnet, 287 U. S. 299 .
15 Cf. Morrissey v. Commissioner, 296 U. S. 344 , 355. The judicial decisions relied on are those cited in the following footnote.
16 Helvering v. Inter-Mountain Life Ins. Co., 294 U. S. 686 ; Helvering v. Illinois Life Ins. Co., 299 U. S. 88 .
17 Cf. Rhine v. New York Life Ins. Co., 273 N. Y. 1 ; 6 N. E. 2d 74 ; Rubin v. Metropolitan Life Ins. Co., 278 N. Y. 625 ; 16 N. E. 2d 293 .
We find it unnecessary to discuss the extent to which such a regulation might, under different circumstances, be given retroactive effect by virtue of the statutory power of the Commissioner.[18] Nor do we find it necessary to discuss the argument that the policy behind the special treatment afforded life insurance companies does not warrant allowing this deduction. For it is our conclusion that by § 203 (a) (2) of the 1932 and 1934 Acts, Congress has granted life insurance companies a deduction for disability reserves which only Congress can take away.[19]
Affirmed.
18 For the Commissioner’s power to promulgate retroactive regulations, petitioner relies on § 506 of the Revenue Act of 1934, which amended § 1108 (a) of the 1926 Act.
