You won't go to jail, unless your obviously trying to defraud them, and even then it's very rare.
You submit stuff, they say "actually we think it is this, prove that it's not", then you send what the actually amount is.
It's only bad when they just take your word and then send actually it's this amount, five years later... then they want all those years worth of difference with whatever the fed interest rate tacked on.
If they just tell you, than that's fine I guess. The problem is, what of those other things happen.
