My DH has had three jobs in the past 6 or so years. He is an account manager and gets paid a salary, and sometimes bonuses but rarely in the last 2-3 years. He pays PAYE tax. He received a letter from HMRC saying that they had no record of receiving a response to the previous two letters they sent and that he owes £400 in unpaid tax from four years ago. There were no previous two letters at all (I open the post). He rang them up and they confirmed this, and told him they would sent out a letter explaining the shortfall and how it was worked out. About a month later, he received a letter from HMRC stating he owes £2,000 in unpaid tax from the last year. No letter regarding the four year ago 'debt'. What the flying fuck?! This is two different employers, both global firms, and we never noticed any additional pay in his salary. I am at a loss - has this ever hapenee to anyone else? I am not sure what to do now. The call centre was less than helpful and I am stressing out! I thought the whole point of PAYE was to avoid this happening? I too work and have never had this happen to me. Any advice greatly appreciated.
