I am trying to file a CT return using HMRC's own software. Company made a charitable donation and there's a box in the Tax Comp to write it back as a non-trading expense. But I can't find any facility for then re-charging it in the 'Charges Paid' box of the CT600 (box 35), so no relief is given in the calculation. The software won't let me do this manually and there's nothing in the Tax Comp part of the package that permits it. Anyone managed to do this? Thanks.
