What you'll need

Your National Insurance number – you'll find this on your National Insurance card, a benefit letter, payslip or P60.

Your child’s details – including their National Insurance number, if they have one.

Details of any Child Trust Fund (CTF) or existing Junior ISA you're transferring.

Before you apply, just remember:

• To apply for a Junior ISA for a child, you must be their parent or legal guardian.
• Once you open the Junior ISA, you'll be the 'registered contact', responsible for choosing investments and managing the account until they turn 18.
• If you’re transferring a Child Trust Fund (CTF) to the Junior ISA, you'll need to be the CTF's registered contact too.
• You’ll need to fund your account with either a Direct Debit from as little as £25, a one off payment of £250 or a transfer from another Junior ISA or Child Trust Fund.
• The value of investments can go down as well as up, and you could lose money for the child as well as make it.
• ISA and tax rules can change, and the benefits of an account depend on personal circumstances.
• We’ll use your data in line with our privacy policy. This explains what data we collect, how we use, share, and store it – including the potential impacts of third parties using your data.

What you need to know about Junior ISAs

• Once money is in a Junior ISA, it can’t normally be accessed until the child turns 18.
• Once the child turns 18, the JISA will turn into a Stocks and shares ISA in the child’s name.
• A child can only have one Stocks and shares Junior ISA or Child Trust Fund open at any one time. Do they have a Stocks and shares Junior ISA or CTF elsewhere? You’ll need to transfer it as part of this application.
• Once you’ve completed the application, it’ll take a few days for the Junior ISA to be set up. During this time, you won’t be able to pay money into the account – but we’ll let you know when it’s set up and ready to go.
