Not so long ago I went through a nearly full year-long IRS audit that went through several of my businesses (several years' business worth of each) and all my personal earnings/filings...literally camped out at my CPA's offices with a desk and room of their own going through record boxes stacked to the ceiling... After all that, the IRS audit's conclusion was that I owed them $0.00 dollars.

You would think I would have been happy & relieved over that.
NO.

My CPA charged me by the hour, so by the time that near year-long audit was finished I had to pay his firm over $60,000+ in fees. (Might have been $80K made me so mad that I forget.) An entire year's salary ++ out the window.

And no, my CPA who was considered one of the best around NEVER told me that the IRS was founded as a Private Trust in Puerto Rico, that the 16th Amendment was never properly ratified, NOR that payment of Federal Income Tax was totally VOLUNTARY.
Not a PEEP. 😡
