A good few months ago I was over paid UC as my boss didn't declare my earnings. I called HMRC up the same day and they said not to worry and they would just sort it out and deduct. I haven't had any UC payments for a while now as I got promoted and earn too much to receive it so theres been nothing to deduct from. I've heard nothing else about paying the overpayment back and I'm not sure what to do now?
