I don’t know anyone who likes to pay taxes. But, you won’t win with these arguments:
Filing tax returns are voluntary: Filing tax returns are not voluntary. The IRS uses the word voluntary to mean that you determine your own initial tax liability by filing your own tax returns, and not have the government determine your liability for you. Actually, if you do not file a tax return, the IRS will give you notice, and may eventually file a “substitute for return” and assess a tax liability. This is fairly common.
Filing tax returns are not constitutional: All you need to do is read the sixteenth amendment. Actually, it is not a bad idea to read the constitution every so often anyway. There are many court cases that support this.
The Internal Revenue Service is not an agency of the United States: The Secretary of the Treasury has full authority to administer and enforce the internal revenue laws and has the power to create an agency to enforce such laws.
If you want to minimize your tax liability, there are many legal ways, otherwise there are penalties and possible criminal prosecution if you try to make these arguments.
