I see reading comprehension is not your strong suit. I cited specifically the 16th Amendment, but if you want to go further back, you need look no further than Article I, Section 8. Specifically the first line of it which states, "The Congress shall have power to lay and collect taxes, duties, imposts and excises,"
Now go fetch your ****in shine box.
I see you conveniently left out the section in the Constitution that directly addresses the direct taxes:
'... direct Taxes shall be apportioned among the several States which may be included within this Union, according to their respective Numbers ...' (from section 2 of Article I)
'... No Capitation, or other direct, Tax shall be laid, unless in proportion to the Census or Enumeration ...' (from section 9 of Article I)
The direct taxes are laid upon the States to pay, not the inhabitants of the States.
Also, the sixteenth amendment federal income tax that you had mentioned is, as we all know — well almost all of us — in the indirect tax category, an excise tax:
Chief Justice Edward D. White, delivering the opinion of the Supreme Court of the United States, and quoting from a previous case, stated: "In the matter of taxation, the Constitution recognizes the two great classes of direct and indirect taxes, and lays down two rules by which their imposition must be governed, namely: The rule of apportionment as to direct taxes, and the rule of uniformity as to duties, imposts and excises." Mr. Justice William R. Day, delivering the opinion of the United States Supreme Court, explained what an excise tax is: "Excises are "taxes laid upon the manufacture, sale, or consumption of commodities within the country, upon licenses to pursue certain occupations, and upon corporate privileges." Cooley, Const. Lim. 7th ed. 680 ...the requirement to pay such taxes involves the exercise of privileges,..."
The Supreme Court has declared that "the provisions of the 16th Amendment conferred no new power of taxation". The tax must be in either one category or the other. It can't be both.
