  "heading": "Section 535A: use of pre-April 2019 residual business losses or deficits",
  "text": "(1) In determining the amount of a gain accruing to a company which is not to be a chargeable gain as a result of section 535A, any pre-April 2019 residual business losses or deficits which—\n(a) have not been deducted from (or taken into account in calculating) other profits or gains (of any kind) of the company or any other person, and\n(b) have not previously been deducted under this subsection,\nmay be deducted from the gain.\n(2) For this purpose “pre-April 2019 residual business losses or deficits” means—\n(a) allowable losses accruing on disposals made before 6 April 2019, or\n(b) deficits or other losses for accounting periods ending before that date,\nwhich would otherwise have been deducted from (or taken into account in calculating) profits or gains (of any kind) accruing to residual business of the company.\n(3) If an accounting period (a “straddling period”) begins before and ends on or after 6 April 2019—\n(a) so much of the straddling period as falls before that date, and so much of it as falls on or after that date, are to be treated as separate accounting periods, and\n(b) if it is necessary to apportion an amount for the straddling period to the two separate accounting periods, it is to be apportioned—\n(i) on a time basis according to the respective length of the separate accounting periods, or\n(ii) if that would produce a result that is unjust or unreasonable, on a just and reasonable basis.\n(4) In determining, for the purposes of subsection (2)(a), the amount of allowable losses accruing on disposals made before 6 April 2019 which would otherwise have been deducted from gains accruing to residual business of the company, section 269ZBA (restriction on deductions) is to be ignored.",
