Joseph Stack's views on taxation follow a long line of protesters who believe tax laws don't apply to them.
Stack is the man accused of ramming a plane into an Internal Revenue Service building in Austin, Texas, last week.
A 3,000-word manifesto posted on a Web site registered in Stack's name accuses the IRS of ruining his life.
Experts say the number of tax protesters isn't large, but their arguments are so enticing that the IRS has published a guide to debunk their claims.
In 2008, the Justice Department was concerned enough to start the "National Tax Defier Initiative" to better coordinate prosecutions.
Stack's writings suggest he was part of a loosely organized movement that stretches back to at least the 1950s.
