How much can I pay into a Junior ISA?
The maximum amount you can pay into a JISA in the current tax year is £9,000 per JISA. Contributions into a JISA don’t count towards your own ISA allowance of £20,000 per tax year.
The minimum amount you can pay into a Moneybox Junior ISA is £1. If you are making an instant bank transfer or receiving a Junior ISA Gift, the minimum payment is £100.
Please note that any contributions into a Junior ISA can only be withdrawn by the child once they turn 18, and so cannot be repaid.
