I got a letter of tax credits the other day saying they were looking back into our award from 2003- 2005. They said it shouldn't affect our award now and they are only looking into a small amount of awards because of an administration error. Hopefully they will owe us some money cos they were only paying us something like £10 a month and we were only earning £15000. Doubt it though! Anyone else had this letter or had their past awards looked into?
