(1)Post-cessation trade relief is not available for an amount for which relief is given, or is available, under any other provision of the Income Tax Acts.
(2)For this purpose—
(a)relief available under section 254 of ITTOIA 2005 (allowable deductions against post-cessation receipts) is treated as given for other amounts before any amount for which post-cessation trade relief is available, and
(b)relief under that section is treated as available if it would have been available but for the fact that the post-cessation receipts (against which the deductions would have been allowed) are exempt under section 524 of this Act.
