Summary

Joseph McKenna Magoun v. Illinois Trust Savings Bank…

An inheritance tax is not one on property, but one on the succession; (2) the right to take property by devise or descent is the creature of the law, and not a natural right,-a privilege,-and therefore the authority which confers it may impose conditions upon it. From these principles it is deduced that the states may tax the privilege, discriminate between relatives, and between these and strangers, and grant exemptions, and are not precluded from this power by the provisions of the respective state constitutions requiring uniformity and equality of taxation.

Joseph McKenna Magoun v. Illinois Trust Savings Bank…

A tax which affects the property within a specific class is uniform as to the class, and there is no provision of the constitution which precludes legislative action from assessing tax on that particular class. By this act of the legislature six classes of property are created, heretofore absolutely unknown. It is those classes of property depending upon the estate owned by one dying possessed thereof which the state may regulate as to its descent and the right to devise.

Joseph McKenna Magoun v. Illinois Trust Savings Bank…

The members of each class are treated alike; that is to say, all who inherit $10,000 are treated alike,-all who inherit any other sum are treated alike. There is equality, therefore, within the classes. If there is inequality, it must be because the members of a class are arbitrarily made such, and burdened as such, upon no distinctions justifying it. This is claimed. It is said that the tax is not in proportion to the amount but yaries with the amounts arbitrarily fixed, and hence that an inheritance of $10,000 or less pays 3 per cent., and that one over $10,000 pays, not 3 per cent.
