Commentary on Sections Overview Overview Section 233: Restrictions on section 232 expenses: the additional calculation rule
857.This section supplements section 232’s application to a taxed receipt where a lease premium receipt is also reduced by reference to that taxed receipt. It is based on sections 37(5) and (7) and 37A of ICTA. The corresponding provision for income tax is in section 293 of ITTOIA.
858.Subsections (2) and (3) provide for a tenant to be treated as incurring an expense for a qualifying day under section 232 only to the extent that the “daily amount of the taxed receipt” exceeds the “daily reduction of the lease premium receipt”. This prevents relief being lost in certain cases where more than one taxed receipt has been used to reduce the lease premium receipt to nil. See Change 13 in Annex 1.
859.The daily amount of the taxed receipt and the daily reduction of the lease premium receipt are calculated according to the formulas in subsection (6):
	the formula for calculating the daily amount of the taxed receipt is the same formula used in section 232(4) to calculate the amount of the expense which the tenant is treated as incurring for each qualifying day; and
	the formula for calculating the daily reduction of the lease premium receipt spreads the reduction calculated under section 228 or the corresponding section in ITTOIA evenly over the receipt period of the lease premium receipt.
860.Subsection (5) deals with the case where for a qualifying day a taxed receipt reduces more than one lease premium receipt. In such a case, the tenant is treated as incurring an expense for that day under section 232 only to the extent that the daily amount of the taxed receipt exceeds the total of the daily reductions of each of the lease premium receipts. See Change 13 in Annex 1.
