EIM32590 | Other expenses: entertainment expenses: disallowance under section 356 ITEPA 2003: employer not liable to UK tax
From HM Revenue & Customs · Employment Income Manual
Sections 356 and 357 ITEPA 2003
Employees of concerns within section 356 ITEPA 2003 (see EIM32575) are not able to claim a deduction for entertaining expenses unless those expenses fall to be disallowed in computing the employer’s taxable profits (see EIM32585). However, you will sometimes come across employees of concerns that, for one reason or another, are not chargeable to UK tax on their profits. The way in which section 356 applies to those employees depends on the reason why the employer is not chargeable.
