Junior ISA Allowance

Junior ISA

Junior ISA explained

What the 2020-21 rules mean for your Junior ISA.

How much can you pay into a Junior ISA (JISA)?

The JISA allowance for the 2020-21 tax year is £9,000. The tax year runs from 6 April 2020 to 5 April 2021.

The allowance cannot be carried over if you do not contribute the full amount in one tax year. A Junior ISA must be opened by a parent or guardian, but after that, anyone can contribute to a JISA, whether they have parental responsibility or not. Contributing to a JISA will not affect your personal ISA allowance.

In a slight quirk of the Junior ISA system, 16 and 17-year-olds currently get two ISA allowances - £9,000 for a Junior ISA and £20,000 they can invest into an adult Cash ISA. Your child can open a Junior ISA if they do not have a Child Trust Fund (CTF) and are under the age of 18. 

Junior ISAs and Child Trust Funds

You cannot have both a Child Trust Fund (CTF) and Junior ISA - but the rules do allow you to transfer your child's CTF into a Junior ISA. If you have made the decision to transfer your child's CTF into a Junior ISA you can open a Junior Stocks and Shares ISA, but you will need to fill out and complete the relevant transfer forms immediately.

The value of any investment can go down as well as up and your child might not get back what was originally invested. The tax treatment of a junior ISA depends on individual circumstances and tax rules may change. If you’re unsure about the suitability of a junior ISA or any investment please speak to a suitably qualified financial adviser.
