BIM72320 - Partnerships: Computation & assessment: Investment Business: Partners Basis Period

You compute the taxed and untaxed income of a partnership that does not carry on a trade or profession as if the partnership was an individual, and then allocate it according to the sharing arrangements in force for the relevant accounting period.

But there is no special basis of assessment rules for any such shares of income. Instead an actual (6 April to 5 April) basis of assessment applies as for individuals (ICTA88/S111 (2) and ICTA88/S111 (3)) (as applied by ICTA88/S111 (10)).
