I know there are lot of these threads and I apologies for asking this question again but I couldn't fin a answer or find any resolved issues. So here's my story: I got letter from HMRC today saying: Your tax credit awards for 2011-12 as a single person. We have selected your award for checks because you have claimed as a single person and the information we hold about you shows Mr xxxxx might be living with you. if they are your partner you should have claimed tax credits as a couple. I Have tried calling citizens advice the helpline gave me no help and I cannot get in touch with my local office but it is constantly busy. I originally started claiming JSA and Child Tax Credits as a single person because my partner wasn't living with us and when he moved in he was waiting for a claim for student finance to be processed to I continued to claim. When his student finance was processed I was worried that we wouldn't have enough money for food, bills ect. so i have continued to claim. Now the girls are in nursery I have been looking for work but to no avail so far. I have no idea what to do.Do I wait to try and get hold of CAB or just phone HMRC and be honest. I am scared of what will happen to me. will this have a knock on effect with the other benefits. Could someone please give me some advice of what to do? Many Thanks in advance
