Going to climb up on my soapbox for a minute. These penalties are asinine beyond belief, and the authorities should be thoroughly ashamed of this. Totally inexcusable. I don't object to "reasonable" penalties for compliance failures, and to be a little bit fair (although it pains me) the IRS is usually pretty reasonable if good faith efforts have been made. But the assumption of guilty until proven innocent just frosts me, particularly when the penalties are all out of proportion to the severity/effects of the violation.
Climbing down now. A long, steep climb...
