GIM10240 | Non-resident insurers: other taxation issues: taxation of non- residents generally
From HM Revenue & Customs · General Insurance Manual
The taxation of UK permanent establishments of foreign general insurers resembles in most respects the taxation of other non-resident companies trading in the UK. For ways in which the corporation tax system applies differently to non-resident companies trading in the UK see, in particular:
CTM56305+ and CFM6300+ - loan relationships: imported losses
CTM56710, CFM6214 and CFM13611 - loan relationships and derivative contracts: unallowable purposes where debits not connected with UK activities
CFM10521 - accounting in currency other than sterling
CG42000 onwards - chargeable gains.
This general alignment of treatment between general insurers and non-resident companies as a whole means that the treatment of non-resident general insurers and that of overseas life insurance companies can sometimes be different. The Life Assurance Manual (LAM) gives details of the treatment of overseas life assurance companies.
