There is an assumption that offshore funds are not involved.
Unit holders in authorised unit trusts, and shareholders in open-ended investment companies, may receive income as an interest distribution or a dividend distribution.
The CTC will make it clear whether the receipt is an interest or a dividend distribution.
Dividend distributions received are treated in the same way as any other UK dividend for income tax purposes.
The equalisation payment is not income and it should not be treated as a capital distribution. It is a return of the initial price paid and it should therefore be deducted from the price paid when computing the chargeable gain on eventual disposal.
