Invest in your child’s future
A Junior ISA (JISA) is a tax-free investment account for children under the age of 18. It is opened and managed by a parent or guardian and only the child can access the money, when they turn 18.
You can invest up to £9,000 each tax year – it won’t affect your personal annual ISA allowance of £20,000 and all your gains will be free from UK taxes.
Plus, earn 2.50% AER (variable) on any money held as cash in your Moneybox Junior ISA, before investing it.

JISA FAQs
If you have any questions, please chat to us in the app or email us via support@moneyboxapp.com.
What is a Junior ISA?
A Junior ISA (JISA) is a savings and investment account for children up to the age of 18. JISAs are an efficient way to save or invest as, like ISAs, they are free from any income or capital gains tax.
There are two types of Junior ISA – Cash and Stocks & Shares. Moneybox offers a Stocks & Shares Junior ISA, which allows you to invest in a range of tracker funds.
The JISA is opened and managed by a parent/guardian and you can pay in up to £9,000 per tax year, which does not count towards your own ISA allowance of £20,000. With a Moneybox Junior ISA, you can also receive gifted deposits from friends and family!
Once the child turns 18, the account matures into a standard Stocks & Shares ISA which they can access and manage.
What happens to my Child’s Junior ISA when they turn 18?
When your child reaches 18, their Junior ISA will automatically convert into a standard Stocks & Shares ISA with Moneybox.
We’ll get in touch with you three months before your child’s birthday to confirm their details, and further payments into the JISA will be frozen one month before your child’s birthday, ready for us to move their full balance over to their new ISA.
On your child’s 18th birthday we’ll reach out to them to help them access their new Moneybox account. Their JISA balance will be transferred across to a Stocks & Shares ISA in their name, which they can access via their own Moneybox account.
How can I open a Junior ISA with Moneybox?
Please note that new Junior ISAs are currently only available to existing Moneybox customers.
If you’re an existing Moneybox customer and you’re on the latest version of the app, you can open a JISA in the Wealth tab. Just tap on Junior ISA in the list of accounts, and you’ll be good to go!
To open the account you’ll need to provide:
The child’s name
The child’s date of birth
The child’s residential address
Contributions to the child’s Junior ISA will be made from your linked bank account, which you can check in Settings > Tap your name > Bank accounts.
How do I transfer a Junior ISA to Moneybox?
Once you have opened a Junior ISA, you can request a transfer in form in Settings > Transfer in an existing ISA. Please note that we are unable to accept partial JISA transfers at this time.
All transfers are processed digitally, so you’ll need to return any completed transfer forms either via the in-app chat, or by email. Once we’ve received your completed form, most transfers are typically complete within 3 weeks.
When transferring a Junior ISA to us, please ensure that the registered contact for both the existing JISA and the Moneybox JISA are the same.
