Hi
As this is a life insurace policy, tax would only be payable on obtaining maturity or early surrender.
IPTM1560 (
Outline of the chargeable events regime: tax charged) advises "A chargeable event gain is deemed to form part of the chargeable person’s income.
In the case of a full surrender, assignment, death or maturity the gain will be assessed for the chargeable period, tax year or accounting period, in which the event happened.
Special rules apply to part surrenders or assignments, involving the concept of an ’insurance year’ at whose end the gain is treated as arising."
Thankyou.
