Tax legislation is not a promise, and a taxpayer has no vested right in the Internal Revenue Code. Justice Stone explained in Welch v. Henry, 305 U.S., at 146-147: “Taxation is neither a penalty imposed on the taxpayer nor a liability which he assumes by con- tract.

Since no citizen enjoys immunity from that burden, its retroactive imposition does not necessarily infringe due process ....” Moreover, the detrimental reliance principle is not limited to retroactive legislation. An entirely pro- spective change in the law may disturb the relied-upon expectations of individuals, but such a change would not be deemed therefore to be violative of due process. Id. at 33-34.
