a transaction ... does not lose its immunity, because it is actuated by a desire to avoid, or, if one choose, to evade, taxation. Anyone may so arrange his affairs that his taxes shall be as low as possible; he is not bound to choose that pattern which will best pay the Treasury; there is not even a patriotic duty to increase one's taxes.

...

Nevertheless, it does not follow that Congress meant to cover such a transaction, not even though the facts answer the dictionary definitions of each term used in the statutory definition. ... the meaning of a sentence may be more than that of the separate words, ... and no degree of particularity can ever obviate recourse to the setting in which all appear, and which all collectively create.

...

The purpose of the section is plain enough, men engaged in enterprises ... might wish to consolidate ... their holdings. ... But the underlying presupposition is plain that the readjustment shall be undertaken for reasons germane to the conduct of the venture in hand. ... To dodge the shareholders' taxes is not one of the transactions contemplated as corporate "reorganizations."

It is earnestly contended on behalf of the taxpayer that since every element required by [the statute] is to be found in what was done, a statutory reorganization was effected; and that the motive of the taxpayer thereby to escape payment of a tax will not alter the result or make unlawful what the statute allows. It is quite true that if a reorganization in reality was effected within the meaning of [the statute], the ulterior purpose mentioned will be disregarded. The legal right of a taxpayer to decrease the amount of what otherwise would be his [or her] taxes, or altogether avoid them, by means which the law permits, cannot be doubted. ... But the question for determination is whether what was done, apart from the tax motive, was the thing which the statute intended. The reasoning of the court below [i.e., the reasoning of the Court of Appeals] in justification of a negative answer leaves little to be said.

When [the statute] speaks of a transfer of assets by one corporation to another, it means a transfer made 'in pursuance of a plan of reorganization' ... of corporate business; and not a transfer of assets by one corporation to another in pursuance of a plan having no relation to the business of either, as plainly is the case here. Putting aside, then, the question of motive in respect of taxation altogether, and fixing the character of the proceeding by what actually occurred, what do we find? Simply an operation having no business or corporate purpose-a mere device which put on the form of a corporate reorganization as a disguise for concealing its real character, and the sole object and accomplishment of which was the consummation of a preconceived plan, not to reorganize a business or any part of a business, but to transfer a parcel of corporate shares to the petitioner. No doubt, a new and valid corporation was created. But that corporation was nothing more than a contrivance to the end last described. It was brought into existence for no other purpose; it performed, as it was intended from the beginning it should perform, no other function. When that limited function had been exercised, it immediately was put to death.

In these circumstances, the facts speak for themselves and are susceptible of but one interpretation. The whole undertaking, though conducted according to the terms of [the statute], was in fact an elaborate and devious form of conveyance masquerading as a corporate reorganization, and nothing else. ... [T]he transaction upon its face lies outside the plain intent of the statute. To hold otherwise would be to exalt artifice above reality and to deprive the statutory provision in question of all serious purpose.
