I have got a sole trader client who has made a loss for 2011 - 2012, and I want to set this against profits of 2010 - 2011. I have entered the figure in box 78 of self-employment pages together with the adjusted profit figure for 2010 - 2011 in box 102.
Do I need to do anything else - like write to HMRC?? Or will the mere fact that there is an entry in box 78 trigger the necessary adjustments from their end?
Thank you for your help - it is only Monday and my brain seems fried already :-)
