Link : excerpts from Aaron Russos's "America: Freedom to Fascism" dealing with the IRS and income taxation.
Of interest, numerous former IRS agents (Joe Bannister among them) have gotten away with not filing US income taxes for many years based on their research of US law, and suggest that it is only through fraud and intimidation that the IRS gets less aware Americans (read: almost everyone) to pay income taxes. Many of those who have looked into the matter in depth say that there is no clear legal obligation for US citizens to pay income tax.
Related, it appears as though the 16th ammendment to the US Constitution (which allowed the IRS and income tax) may not have been not properly (read: legally) ratified, as per http://www.libertyforlife.com/constitution/us-16th-failed-ratification.htm and related links...
Let's go. :)
