Hi, my boyfriend just received a letter from revenue re his tax returns for 2006 to 2008 saying that there were no provisions for addbacks/adjustments and kindly state the reason or send them any computations. He is a contractor and the only addbacks/adjustments he had were deprectation and capital allowances and they are both included on the CT1's. Can anyone help me as to what I should do here? Does this mean he is getting a revenue audit?? Any help would be greatly appreciated...thanks..
