Seems like I remember one story from a while back about a lady who got in the same trouble for routinely making deposits right under $10,000, and the IRS grabbed everything.
Turns out the reason she was doing this is that her insurance company only insured her for amounts of cash under $10,000.
I know a guy that owns a C-store that is 35 miles from the nearest bank. He used to make his deposit weekly and was often over the $10,000. The IRS and the Secret Service showed up one day and wanted to see his books. They found nothing wrong but it infuriated him. Now he goes out on Friday with two armed guards and pays his bills in cash. Annoys the beer distributors but tough cookie.
