The Congress shall have power to lay and collect taxes on incomes, from whatever source derived, without apportionment among the several States, and without regard to any census or enumeration.
Is it your contention that after this was passed, Congress never followed up and passed an income tax? Just trying to understand your position.
And of course you have not read relevant Supreme Court rulings that say the 16th Amendment did not give to the Government a third way of taxation nor did it increase the Government’s taxation authority.
If there is no statute and there is no law passed by Congress, then the rulings of any court stating that one must pay tax of one’s income are completely spurious.
Quoting cases doesn’t do it.
Show me the law passed by the Congress of the United States of America that says one must pay a federal tax upon one’s income.
