Portrait of Harlan F. Stone Harlan F. Stone Welch v. Henry — Opinion of the Court

Taxation is neither a penalty imposed on the taxpayer nor a liability which he assumes by contract. It is but a way of apportioning the cost of government among those who in some measure are privileged to enjoy its benefits and must bear its burdens. Since no citizen enjoys immunity from that burden, its retroactive imposition does not necessarily infringe due process, and to challenge the present tax it is not enough to point out that the taxable event, the receipt of income, antedated the statute.

The bare fact that the present tax is imposed at different rates and with different deductions from those applied to other types of income does not establish unconstitutionality. It is a commonplace that the equal protection clause does not require a state to maintain rigid rules of equal taxation, to resort to close distinctions, or to maintain a precise scientific uniformity. Possible differences in tax burdens, not shown to be substantial, or which are based on discrimination not shown to be arbitrary or capricious, do not fall within the constitutional prohibition.

Nor is the tax any more a denial of equal protection because retroactive. If the 1933 dividends differed sufficiently from other classes of income to admit of the taxation, in that year, of one without the other, lapse of time did not remove that difference so as to compel equality of treatment when the income was taxed at a later date. Selection then of the dividends for the new taxation can hardly be thought to be hostile or invidious when the basis of selection is the fact that the taxed income is of the class which has borne no tax burden.
