s 87 Ring fence trades
(1) This section applies if— (a) a person makes a loss in a tax year carrying on oil-related activities (within the meaning of section 16 of ITTOIA 2005), (b) those activities are treated under that section as a separate trade for the tax year or a subsequent tax year, (c) the person makes profits in a subsequent tax year from other activities, and (d) the other activities and the oil-related activities would, but for that section, together form a single trade. (2) For the purposes of carry-forward trade loss relief for the loss, the person may treat profits from the other activities in a subsequent tax year as if they were profits of the separate trade (despite section 16 of ITTOIA 2005).
