Tax resistance in the United States has been practiced at least since colonial times, and has played important parts in American history.
Tax resistance is the refusal to pay a tax, usually by means that bypass established legal norms, as a means of protest, nonviolent resistance, or conscientious objection. It was a core tactic of the American Revolution and has played a role in many struggles in America from colonial times to the present day.
In addition, the philosophy of tax resistance, from the "no taxation without representation" axiom that served as a foundation of the Revolution to the assertion of individual conscience in Henry David Thoreau's Civil Disobedience, has been an important plank of American political philosophy.
