So much for your garbage about wages and salaries being in the Internal Revenue Code and applying to Mrs. Kuglin. And even if some regulation mentions wages and salaries (not mentioned by USC 26 itself), it obviously is a benign regulation. That's part of the reason the IRS would not answer Mrs. Kuglin's simple request(s).
As for your question about "fees and compensation for services," a corporation can receive fees and compensation for services; a wage worker such as Mrs. Kuglin does not!
Given your extensive knowledge of collectivists and Bolsheviks, I'm surprised at your lack of knowledge of the tax system. While the basic law is contained in Title 26 of the US Code, the IRS has ample regulatory authority which for tax payers has the effect of law. Such are the Internal Revenue Code, 26CFR, Treasury Regulations, Treasury rulings, IRS rulings and decisions, and thousands of court decisions. If you had a half way open mind, the many posts you have read on this thread would have at least prompted you to try civility rather than crass name calling. I assume that's your way of telling those of us you disagree with that you really don't have an argument....but you want one.
But hey! Talk is cheap. Put your money where your mouth is and refuse to pay any taxes. I really don't give a $hit. As for your hero Kuglin, I put her in the same category as that other famous tax evader...Big Al. To believe is that "Income from whatever source derived" doesn't include salaries and wages is akin to that other famous saying....Well, that depends on what the meaning of sex is..."
