You're asking how you opt out of taxes. You don't.

And everything you earn isn't rightfully yours. It's supported by an infrastructure of national defense, courts, police, building regulations, and so forth. You get many years of public school for free. Etc. etc. You didn't do this solo.

So the cost of all the benefits you get as a citizen is to contribute your rightful share, that share being decided democratically in which you have a vote.
