I had a client get about their THIRD letter demanding payment of tax NOT owed - they filed about a week before the UI exclusion. They've actually paid the small amount of tax that was really due, but keep getting auto-letters demanding a lot more, that is NOT owed, and every time they get a new letter they call me in a panic. And I tell them, *again*, that the letters are being sent out by computer and that they don't owe $2K.
I am SO sick of this. And there is nothing anyone can do.
