Yes, you do have the right to question the IRS. I do it all the time. The IRS is a non-government entity of foreign source that has no lawful jurisidiction in the United States of America. There is also no law reported in the Federal Register that states that one is personally liable to file income tax "returns". All that is ever stated to citizens is some Title 26 U.S.C. which is private law and has no lawful force unless it is recorded in the FR. Noone is obligated to testify against themselves to "perjure" themselves on some bogus "return". To do so, that individual waives their constitutional rights. I question the law when it involves "voluntarying" my hard earned money and my personal rights under the Fifth Amendment. As much as citizens are expected to abide by the laws so are government officials. As for the IRS, they are outside the law. In fact, they are outlaws which need to be investigated under the RICO statute!
