SAIM2430 - Interest: taxation of interest: children's accounts
Accounts held by unmarried minor children
Interest arising on an account held by an unmarried person under 18 is treated as income of his or her parent if
- the money in the account was a gift from the parent, and
- the interest exceeds £100.
The gift constitutes a settlement and ITTOIA05/S629 (1) applies to treat the interest as income of the settlor. There is more detailed guidance, with examples, at TSEM4310.
