BIM90135 | Post-cessation receipts and expenses: carry forward of unrelieved post-cessation expenses
From HM Revenue & Customs · Business Income Manual
Carrying forward to set against post-cessation receipts is the last possible mechanism of relief for post-cessation expenses
As discussed in BIM90090, once all other methods of relief have been applied the only way of setting off any remaining post-cessation expenses is to carry them forward to set against post-cessation receipts of the same trade.
