It has recently come to my attention that I was incorrectly paid in the years 2002 and 2003. The company in question has agreed to pay me the arrears as it was not my fault but an error on their part. The sums in question were approx. €3500 per year (ie.€7000 in total). I got a cheque that taxed these amounts at 41%, even though in first year, my salary didnt even reach this tax bracket (I havent cashed this cheque yet). They have not issued me with any revised P60's for those years or updated my pension to reflect this underpayment and are refusing to do so as they say that they no longer have me on their system. Am I entitled to these? What are my rights? I have no idea. Also, a friend suggested that I should have asked for interest on the amount due. I reckon its too late now in any case.
