Help your child’s savings work harder

A Junior ISA (JISA) is a great way to invest in your child’s future. It’s a tax-free investment account for children under the age of 18, which is opened and managed by a parent or guardian – but 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 income and capital gains tax.

Plus, earn 3.25% AER* (variable) on any money held as cash in your Moneybox Junior ISA, before investing it.

Tax treatment depends on individual circumstances and may be subject to change in the future.

Moneybox makes it easy

With Moneybox, you have access to plenty of tools and features that make it easy to manage your JISA – all within the app. Including:

  • Instant bank transfers
  • Open JISAs for multiple children
  • Transfer in other JISAs to Moneybox
  • Get help from our dedicated support team
  • Receive gifted deposits from family and friends with Junior ISA Gifts

Who can open a Moneybox JISA?

To open a Moneybox Junior ISA you need to be a UK resident aged 18 or over and be the parent or guardian of a child under 18 years old. You must also already be a Moneybox customer.

The child must be a UK resident and they can’t already have a Child Trust Fund. If your child already has a Junior Stocks & Shares ISA you can transfer it into a Moneybox Junior ISA, free of charge.

It's important you know

Capital at risk. All investing should be for the longer term. The value of your investments can go up and down, and you may get back less than you invest. Tax treatment depends on individual circumstances and may be subject to change in the future.

A 25% government penalty applies if you withdraw money from a Lifetime ISA for any reason other than buying your first home (up to £450,000) or for retirement, and you may get back less than you paid into your Lifetime ISA.

Your home may be repossessed if you do not keep up repayments on your mortgage.

Payments you make into your pension won’t be accessible until the minimum pension age (currently 55, increasing to age 57 from 2028). Tax treatment depends on individual circumstances and may be subject to change in the future.
