CTM34270 - Residence: non-resident companies: distributions received
UK company distributions received by non-resident companies do not constitute franked investment income (see CTM34230) and are specifically excluded from the income of a branch or agency (see (b) of CTM34210). In principle, they are within the charge to IT but ITTOIA05/S399 (2) - qualifying distributions received by persons not entitled to tax credits, and ITTOIA05/S400 - non qualifying distributions, provide that income tax is treated as having been paid at the dividend ordinary rate and hence there is no liability
