And now, in 2012, Justice Roberts has confirmed that there are no limits to regulatory taxation as long as the revenue is deposited in the U.S. Treasury.
Are there any other limits? Article I, Section 2 says that “direct taxes shall be apportioned among the states” according to population. This is repeated in Article I, Section 9, which says that “no capitation, or other direct tax, shall be laid,” unless apportioned.
The Supreme Court struck down income taxes in 1895 (Pollock v. Farmers’ Loan & Trust Co.), on the ground that they were “direct” taxes but not apportioned by population. Apportioning an income tax would defeat the purpose of the relatively poorer Southern and Western states, who wanted the relatively richer states of the Northeast to pay the bulk of the tax. The 16th Amendment gave Congress the power to tax incomes without apportionment.
Other direct taxes should presumably have to be apportioned according to the Constitution. Justice Roberts quickly dismissed the notion that the individual mandate penalty-tax is not a direct tax “under this Court’s precedents.” To any sentient adult, it looks like a “capitation” or head tax, imposed upon individuals directly. Unfortunately, having plenty of other reasons to object to ObamaCare, the four dissenting justices in NFIB v. Sebelius did not explore this point.
Some conservatives have cheered that part of Justice Roberts’s decision that limits Congress’s Commerce Clause power. But an unlimited taxing power is equally dangerous to constitutional government.
