What is the 2025/26 Junior ISA allowance?
The Junior ISA (JISA) allowance for the 2025/26 tax year is £9,000. The tax year runs from 6 April 2025 to 5 April 2026.
The allowance cannot be carried over if you do not contribute the full amount in one tax year.
Anyone can contribute to a JISA, whether they have parental responsibility or not. However, the Junior ISA must be opened by a parent or guardian.
Contributing to a JISA will not affect your personal ISA allowance.
How do I open a Junior ISA?
New customers will need to open a Stocks and Shares ISA or Trading Account on our Investor or Super Investor plans before adding a Junior ISA at no extra cost. Junior ISAs are not available on our Investor Essentials plan. Read our Junior ISA Fees and charges for more.
- You can open a Stocks and Shares Junior ISA simply by logging into your account and clicking 'add an account' from the top right-hand menu.
- Children can hold a maximum of one Cash Junior ISA and one Stocks and Shares Junior ISA. They must be aged under 18, at which point the account becomes a regular ISA.
- A Junior ISA is a tax-efficient way to invest in your child's future, but remember that investments can fall in value as well as rise, so your child could get back less than you put in.
What is the Child Trust Fund annual allowance?
Both Child Trust Funds (CTF) and Junior ISAs (JISA) enjoy a tax-free allowance of £9,000 for the current tax year (2025/26).
