- 5 - e.g., James v. United States, 970 F.2d 750, 753 n.6 (10th Cir. 1992); United States v. Neff, 954 F.2d 698, 699 (11th Cir. 1992); Freas v. Commissioner, T.C. Memo. 1993-552; Andreas v. Commissioner, T.C. Memo. 1993-551. Petitioner argues that he is not obligated to pay Federal income tax because (1) the Internal Revenue Code does not assign a value to the “exempt amount”, (2) the “exempt amount” appears in IRS publications and instructions “ex post facto”, and (3) he is not required “to comply with a law ‘ex post facto’”. Petitioner’s argument is incomprehensible. If petitioner means to assert that the taxation of income in excess of the exempt amount is an ex post facto law in violation of Article I of the Constitution, that argument has no merit. The constitutional prohibition against ex post facto laws applies only to penal legislation that imposes or increases criminal punishment for conduct predating its enactment. Harisiades v. Shaughnessy, 342 U.S. 580, 594 (1952). The Ex Post Facto Clause is not applicable in a civil context. Johannessen v. United States, 225 U.S. 227, 242 (1912). The Federal income tax imposed under the Internal Revenue Code is not penal legislation and does not impose or increase criminal punishment. Accordingly, imposition of Federal income tax on income in excess of the exempt amount does not violate the Ex Post Facto Clause of the U.S. Constitution. See Karpa v. Commissioner, 909 F.2d 784 (4th Cir. 1990) (retroactivePage: Previous 1 2 3 4 5 6 7 8 9 Next
