Junior ISA Allowance 2024/2025

The Junior ISA allowance this tax year is £9,000

Each child has their own Junior ISA allowance which is separate from their parents’ or guardians’ own ISA allowances.

This means that parents and guardians can save or invest up to £9,000 per year in a Junior ISA for a child under the age of 18.

The Junior ISA allowance is the same for both cash and stocks and shares Junior ISAs. You can split the allowance between the two types of accounts, but you cannot exceed the overall limit of £9,000.

For example, you could save £4,000 in a Junior Cash ISA and £5,000 in a Junior Stocks and Shares ISA in the same tax year.

A child can only have a maximum of one Junior Cash ISA and one Junior Stocks and Shares ISA at any one time. And they can’t access the money until they turn 18.

The tax year runs from 6 April to 5 April, and the deadline to add money to a Junior ISA in the 2024/2025 tax year is 11:59pm on 5 April.

Junior ISA tax rules can change, and their benefits depend on individual circumstances.

Child trust fund allowance

Children born between 1 September 2002 and 2 January 2011 could have a Child Trust Fund. A Child Trust Fund has its own separate annual allowance of up to £9,000. If you transfer a Child Trust Fund to a Junior ISA, the child will get their full Junior ISA allowance of £9,000 regardless of how much Child Trust Fund allowance has been used.

This means you could add up to £9,000 to a Child Trust Fund, transfer it to a Junior ISA and then add up to a further £9,000 after the transfer is complete, meaning up to £18,000 could be added to their tax-efficient account in the same year. It would need to be done in this order as a child cannot have a Junior ISA and Child Trust fund at the same time.
