I requested balancing statement at end of 2006, due some tax back for medical expenses, bins taxes etc. I had changed employment during the year, and had been out of work for a little while so I wasn't clear on my tax situation. Got a p21 statement very quickly showing a large overpayment of tax on my part and a cheque attaching. I cross checked some of the maths, all looked ok and gratefully took and accepted it. Today got an amended p21 statement showing that I had underpaid tax by almost the full amount refunded to me above and looking for a cheque in settlement. I don't have the money to repay it (long since spent). I genuinely thought it was mine, never occurred to me that they would pay the money out unless the tax office were sure too. What are my next steps. Will revenue accept a payment over a period of time, will they accept some sort of reduced settlement. I do understand errors can happen, but no apology, explanation, no meet you half way on this, nothing. Anybody had this happen to them before?
