Summary Box

Account name

Smart Junior ISA

What is the interest rate?

3.25% AER/tax-free (variable)

Interest is calculated daily on each whole pound and paid into the Smart Junior ISA annually on 31 October and on closure.

Can Nationwide change the interest rate?

Yes, the interest rate is variable. This means we have the ability to change the interest rate. Please see the ‘Interest’ section of the Savings General Terms and Conditions (and from 1 May 2018, the ‘Variation of your interest rate and other account terms’ and ‘How we will tell you about interest rate changes?’ sections of the new Cash ISA General Terms and Conditions) which sets out when we can vary the interest rate and how and when we’ll notify you if this happens.

What would the estimated balance be after 12 months based on a £1,000 deposit?

The balance on an initial deposit of £1,000 with an interest rate of 3.25% AER/tax-free (variable) after 12 months would be £1,032.50.

This estimated balance is for illustration only and assumes that:

  • the account was opened on 1 November
  • interest is paid into the account
  • no further deposits or withdrawals are made
  • there is no change to the interest rate
  • individual circumstances do not change.

How do I open and manage my account?

To open this account:

A parent or legal guardian can open the ISA on behalf of the child, or if the child is aged 16 or 17 years old they can open the Smart Junior ISA themselves:

  • The child must be under 18 years old and a UK resident. Please note, the account can’t be closed until the child is 18.
  • You can open the account with a minimum of £1, up to the annual Junior ISA allowance (currently £4,260 for the tax year 2018/19).

Please note:

  • You can only have one Junior ISA or Child Trust Fund account at any one time with Nationwide or another provider. If you already have one of these, you’ll need to request a transfer pack to open and move your existing Junior ISA or Child Trust Fund account.

You can open this account:

  • using the 'Start application' button below this Summary Box

  • in branch.

Please note: On opening, you can only add funds from a Nationwide current account or instant access savings account. Once opened, you can add funds from other accounts.

You can manage your account:

Please note:

  • There is no maximum balance you can hold as long as you stay within your Junior ISA allowance each tax year. You can make unlimited deposits up to the annual Junior ISA allowance each tax year.
  • You can transfer your account to another provider at any time.

It’s easy to move your savings between your existing Nationwide savings accounts or to open a new savings account with us. Simply go to, use our Banking app or visit one of our branches.

Can I withdraw money?

No, withdrawals aren’t allowed until the child’s 18th birthday.

Upon reaching 18 only the child, and no one else, can withdraw the money.
