What is a Junior ISA?
ISA stands for Individual Savings Account. A Junior ISA is a tax-free savings account for an eligible child under 18. The money belongs to the child, even when an adult opens or manages the account.
A cash Junior ISA holds savings; a stocks and shares Junior ISA invests the money, so its value can fall as well as rise. A child can have both types, but contributions share one annual limit.
The rules to understand before paying in
- In the 2026–27 tax year, the combined Junior ISA contribution limit is £9,000. It is a limit for the child, not a separate allowance for each parent or grandparent.
- A parent or guardian with parental responsibility can open and manage an account.
- The child can take control at 16 and can normally withdraw the money at 18. Parents cannot simply take it back after separation.
- A child cannot hold a Child Trust Fund and a Junior ISA at the same time. Ask the provider about a transfer if there is an existing Child Trust Fund.
Separate today’s costs from long-term savings
If you need money available for shoes, a school trip or a replacement laptop, keep that planning separate from savings locked away until adulthood. Also keep a maintenance payment separate: putting money into savings does not automatically meet an obligation to pay regular maintenance.
There is no need for identical contributions if your incomes differ. A voluntary savings plan can use amounts each parent can sustain. It should not leave the child’s current essentials unpaid.
Agree how the account will be managed
- Find out whether an account already exists, who manages it and how much has been contributed this tax year.
- Ask the provider how statements, contributions and any change of registered contact are handled.
- Write down how you will coordinate contributions from both households and relatives.
- Decide when to review the amount you can afford, especially after an income change.
- Keep account details securely, without sharing personal banking passwords.
What if the savings are in an adult’s name?
Do not treat every account labelled “for the child” as a Junior ISA. An adult-owned account and money legally owned by the child have different consequences for access and control. Ask the provider what kind of account it is before moving money or promising how it will be used.
If control of an existing account is disputed, the provider can explain its procedures. The ownership question may need individual advice; the label on a household spreadsheet does not settle it.
This guide explains general rules and services. It does not assess your individual case.
