CIRD12610 | Core computational rules: deductible debits: general matters and adjustments for tax purposes: disallowance of expenditure: criminal payments
From HM Revenue & Customs · Corporate Intangibles Research and Development Manual
CTA09/PART8/S865 (3)(c)
Exceptionally, debits otherwise deductible under CTA09/PART8 may arise in respect of expenditure within CTA09/S1304. That is expenditure:
in making a payment which constitutes a criminal offence, or
in making a payment induced by blackmail or extortion.
S865(3)(c) ensures that debits of this nature are disallowed. The guidance at BIM43100 onwards should be applied in identifying these payments.
