Here you go. If you think you need to go cash only, here is a great reason why: Law Lets I.R.S. Seize Accounts on Suspicion, No Crime Required. In this case, if you consistently deposit less than $10,000 in cash into your bank account, the IRS can take the money. Period. No charges, because you haven't done anything wrong.
The real kick in the guts is, you have to prove a negative, i.e. you are innocent to get it back. And it can take most, if not more of the money that was seized to get it back. Now I am a self-admitted old "fuddy-duddy" who actually reads the Constitution, which, the last time I looked, the 5th Amendment reads, "...nor be deprived of life, liberty or property, without due process of law;" This most assuredly a deprivation of both life and property. You lose your livelihood by being unable to sustain your business, and that cash is your property. Your government at work, folks.
