The 16th ammenendment is a farce, We have been lied to by the IRS ever since it was passed. There is no code or law that says an American citizen must fill out a W4 form. The W4 form is for foreign workers. It is voluntary for a US citizen. Look it up in the IRS laws. Your employer can not make you fill one out to get a job, it is fraud by your employer and the IRS. If you work for a living and have no investment income and dont own a business there is no law or code requiring you to file a tax return.
