What happens to Junior ISA when my child turns 18?

When your child reaches 18, their Junior ISA will automatically convert into an adult Stocks & Shares ISA with Moneybox.

We’ll get in touch with you a few weeks before your child’s birthday to confirm their details, then will reach out to them to help set up their new Moneybox account. Once your child’s 18th birthday has passed, their JISA balance will be transferred across to a Stocks & Shares ISA in their name, which they can access via their own Moneybox account.
