Yes it's true that Steve Miller, former Director of the Internal Revenue Service (IRS ) admitted at a Congressional hearing that the taxes collected by the IRS are not mandatory – but voluntary. When questioned at the House Ways and Means Committee (WMC) hearing, Miller told House Representative Devin Nunes that “America’s tax system is ‘voluntary’”. When Nunes remarked for clarification that the US tax code is a “voluntary system”, Miller said, “Agreed.”
That is NOT to say, "don't file income taxes" because if one has received ANY INCOME through the SSN/Person they are liable for taxes. Payments through a Social Security Number will result in a "federal employee" classification, thus the [probably correct] assumption that one has an obligation of taxes. The US government and it's courts will see statements such as "the tax system is voluntary" as "tax protester arguments" and throw the book at that individual. The truth is, taxes are 100% legal and lawful and 99.99% of people reading this are liable for income taxes because they indorse the use of private credit (FRNs). Do not expect to get a "fair trial" when facing the US government as a tax protester!
Furthermore, one cannot just "donate all their money" to an FBO Trust and have it be tax-deductible. Not only will this set-off red flags within the IRS's automated system, it will most likely land one in hot water.
NOTE: If one wishes to file a Form 4361 with the IRS, we suggest seeking a professional (CPA, attorney, tax professional) before making any decisions.
