A tax-free savings account for children up to the age of 18.
A parent or guardian can manage this ISA for a child while they’re under 16. Once the child reaches 16, they can manage their account online.
You cannot make withdrawals from a Junior ISA until the child’s 18th birthday. On this date, the Junior ISA ends and we’ll automatically transfer the money into an adult cash ISA provided by NS&I. We’ll contact the person who manages the account about a month before this happens.
Pay by bank transfer or standing order
Anyone can top up a child’s Junior ISA by bank transfer. All deposits must be from a UK bank account.
Any deposits that would exceed the annual subscription limit will be automatically refunded in full to your bank account, so you may want to check before making the deposit.
Your money will take up to five working days to reach your account. This is because NS&I is not a bank, so we can’t receive payments directly into individual NS&I accounts – they have to go through our clearing bank first.
To cancel, please contact your bank: not NS&I.
Prefer to top up by debit card?
Only the person who manages the Junior ISA can top it up by debit card. Make sure to use your own UK debit card.
It can take up to 26 days for your previous provider to send the money. As soon as we receive it, we’ll update your balance.
When the child reaches 16, they can manage their savings until their 18th birthday, when the Junior ISA ends. They’ll need to download and print a registration form - this is because we need their signature.

If you’re the parent or guardian and you’re still looking after the Junior ISA, please make sure you let your child know what’s going to happen to their account on their 18th birthday. They’ll need to register online to access and manage their new ISA.

Before we can open the Junior ISA, we’ll need confirmation of the child’s identity, and we may also need you as the parent or guardian to confirm your identity and address.
We’ve tried to make this as easy as possible – instead of having to send us documents by post, you can just take a photo of each document we ask for and upload it to our secure website.
Shortly after we receive your application to open an account, we’ll email you to ask you to upload your document photo(s).
You can open a Junior ISA as a parent/guardian on behalf of your child under 18. You can also open a Junior ISA for yourself if you are 16 or 17.
