Or your perceived knowledge. One would assume that if you wrote a book titled Cracking the Code: The Fascinating Truth About Taxation In America, that you would be very familiar with this:

That’s the code. Four thousand some-odd pages of pure ecstasy.
Tax Update Blog tells us about Peter Hendrickson who is the author of Cracking the Code and his problems doing just that:
DOJ press release via TUB:

The 10-count indictment charged that for the calendar years 2000, 2002,2003, 2004, 2005 and 2006 Hendrickson filed IRS Form 1040 (income tax returns) and/or IRS Form 4852 (Substitute for Form W-2) stating under penalties of perjury that he had received no wages in those years. The indictment indicated that he had in fact received wages in those years in varying amounts. The evidence produced at trial established that Hendrickson had in fact received taxable wages and that his claims to the contrary were knowingly false. In reaching the verdicts, the jury rejected Hendrickson’s defense that he had a good faith belief that his statements regarding his lack of wages were true.

Followed by Joe Kristan’s thoughts:

The tax code is an awful mess, and Congress never passes up a chance to make it worse. That doesn’t mean there is a secret formula from the Illuminati that you can invoke to make it part for you like the Red Sea did for Moses.

Or that you can’t publish a book that probably cites said formula.
