I'm writing a work of fiction that involves some criminal activity, and I'm having a hard time understanding how that would affect the accountant in this situation. The work is set in the US, in the 1980s.
Bob and some friends decide to go "off the grid" for an extended time (ie several decades). These people intend to form their own private community and withdraw themselves from modern society. There are definitely laws that this would break (see my older question here), from taxes to hunting and fishing to child education and so on. None of these are violent crimes and they aren't trying to hurt anyone, but this is definitely not legal.
To try to prevent their discovery, Bob plans ahead and secures the help of an accountant, Alice. He has a large endowment, and from it Alice draws a stipend and pays Bob's taxes for him. Bob figures if he pays his taxes, no one will ever come looking and see what they're up to. The endowment is sufficient to pay Bob's taxes and Alice's salary indefinitely.
Here's the question. Alice knows that Bob is probably breaking the law even if she's no legal expert. And she's willingly helping him. But her accounting work is all legal. She pays the taxes due in Bob's name legally and faithfully. And she isn't technically helping him hide or break those other laws just by serving as an accountant. Is Alice criminally liable? If so, is her liability any more severe because she is an accountant? Or is her liability no different than an average person who knows what Bob is up to and helps him here and there?
