I don't think they can legally make people file taxes for seven years after leaving a state, maybe rich people who didn't pay and owe them taxes in some arrangement to pay arrears. I don't think that stands a chance holding up in the SC. No one can just go into your bank account and take your money without a legally binding judgement against you. A large out of state bank once did that to me, they took a check I wrote them and ran it through my account twice using two different routing numbers. They refused to give it back. I got a lawyer and I ended up getting, after paying the lawyer, about ten times the amount that check was written for.
