(a) General. Section 269 is designed to prevent in the instances specified therein the use of the sections of the Internal Revenue Code providing deductions, credits, or allowances in evading or avoiding Federal income tax. See Sec. 1.269-3.
(b) Disallowance of deduction, credit, or other allowance. Under the Code, an amount otherwise constituting a deduction, credit, or other allowance becomes unavailable as such under certain circumstances. Characteristic of such circumstances are those in which the effect of the deduction, credit, or other allowance would be to distort the liability of the particular taxpayer when the essential nature of the transaction or situation is examined in the light of the basic purpose or plan which the deduction, credit, or other allowance was designed by the Congress to effectuate. The distortion may be evidenced, for example, by the fact that the transaction was not undertaken for reasons germane to the conduct of the business of the taxpayer, by the unreal nature of the transaction such as its sham character, or by the unreal or unreasonable relation which the deduction, credit, or other allowance bears to the transaction. The principle of law making an amount unavailable as a deduction, credit, or other allowance in cases in which the effect of making an amount so available would be to distort the liability of the taxpayer, has been judicially recognized and applied in several cases. Included in these cases are Gregory v. Helvering (1935) (293 U.S. 465; Ct. D. 911, C.B. XIV-1, 193); Griffiths v. Helvering (1939) (308 U.S. 355; Ct. D. 1431, C.B. 1940-1, 136); Higgins v. Smith (1940) (308 U.S. 473; Ct. D. 1434, C.B. 1940-1, 127); and J. D. & A. B. Spreckles Co. v. Commissioner (1940) (41 B.T.A. 370). In order to give effect to such principle, but not in limitation thereof, several provisions of the Code, for example, section 267 and section 270, specify with some particularity instances in which disallowance of the deduction, credit, or other allowance is required. Section 269 is also included in such provisions of the Code. The principle of law and the particular sections of the Code are not mutually exclusive and in appropriate circumstances they may operate together or they may operate separately. See, for example, Sec. 1.269-6. [T.D. 6595, 27 FR 3596, Apr. 14, 1962]
