@qbteachmt Most people know they will be pursued, but they may have a different idea on how to use the money rather than paying it to the government.  For example, at the time most of these taxes were assessed in 2013, Intuit was selling for about $60 a share.  If they had invested in tax software instead of paying IRS, their shares today would be worth more than $650.  

These taxpayers instead chose to invest in a nutritional supplement company.  We don't know how much it's worth because it's not publicly traded.  But for now, I picture them laughing all the way to the bank.
