Is it against the law to not file your taxes, and how did the 16th amendment pass anyways? ?

If the 16th amendment wasn't even ratified by the appropriate number of states how did it pass? Is there any law that says we actually have to file our taxes anyways?

Yes, it is against the law to not file your taxes.

The 16th amendment was properly ratified. The people who believe it wasn't properly ratified are wrong. The following link is to a court case explaining it. http://bulk.resource.org/courts.gov/c/F2...
Bill Benson claims to have researched the issue for over a year for his book. It took me all of five minutes to find that he misinterpreted the Tennessee State Constitution as it was written in 1909.

The current income tax laws are codified as Title 26 of the U.S. Code. You can read it at http://www4.law.cornell.edu/uscode/26/ or at http://www.access.gpo.gov/uscode/title26...
Section 1, 61, 62, 63, 3402, 6001, 6011, 6012 and a few others apply to most people. Section 7203 is the specific section making it a crime to willfully fail to file a tax return.

The argument that you are making is pointless. It has been rejected over and over. You must pay your taxes whether you approve or not.
The 16th amendment exists regardless of the method by which it was adopted.

I don't like it either, but I pay my taxes and I stay out of jail.

Yes, there is. The hair-splitting is whether you do your taxes yourself, or have them calculated by an accountant or the IRS. Failure to file taxes is classed as tax evasion and can have severe penalties.

Go ahead and believe the propaganda and do not pay your taxes, see what will happen next esp trying that defense in front of a judge while you are sitting in jail

Just pay them and stop trying to find loopholes. The majority of people can manage that very well.
