Does it matter? Do you think that if you haven't heard about paying income tax, you wouldn't have to pay it? Help me out here.
You would find out that you need to file taxes when you receive tax forms from either your employer or other source of income. When you are filing out your tax forms you will realize that you need to pay taxes on your income
You understand this is circular logic right? You employer doesn't have the right to tax you. You say you find out you owe the tax while filling out the tax form? That form is called a tax return. You ever wonder why they call it a return? It is called a return because tax agents went out to each tax payer and filled out the form for them by asking the questions on the form. The agent would then return the form to the IRS. The income tax violates the Fourth and Fifth amendments. We have a right to be secure in our persons and free from unreasonable searches and we cannot be forced to testify against ourselves.
