What is the junior ISA allowance?
There is a limit to how much you can pay into a child's junior ISA (JISA) each tax year. This is called your JISA allowance and it’s a fixed amount set by the government that doesn’t vary between providers.
JISA allowances reset every tax year end, just like with other ISAs.
Current junior ISA annual allowance
The maximum amount you can put into a JISA in the 2024/2025 tax year is £9,000. This has stayed the same since the 2020/2021 tax year, but may change in the future.
The tax year is the 12-month period that the government uses to calculate taxes and organise finances and accounts. In the UK, the tax year ends on 5 April, with the new tax year starting on 6 April.
Previous junior ISA annual allowances
The last time the JISA annual allowance changed was in April 2020, when it went from £4,368 in the 2019/2020 tax year to the £9,000 that’s still active today.
Previously, the allowance had been increasing steadily each year from £3,600 in 2011, when JISAs were first introduced.
Managing the junior ISA allowance
It is important to be aware of the JISA annual allowance as you could be fined by HMRC if you go over it. Therefore, you need to keep an eye on who is paying money in.
Although you have to have parental responsibility to open a JISA for a child, anyone can pay into it. This is especially relevant around birthdays, Christmas and events like graduations.
If you want to pay into a JISA for someone else’s child, make sure you check with their parent or guardian first so you don’t accidentally max-out their allowance.
You can pay into a JISA as often and as much as you like, but you must stay within the yearly £9,000 allowance.
Regular payments, like a monthly Direct Debit, can be useful to help you build your child’s savings over time, though one-off payments can be just as effective and a great gift idea. The minimum amount you can pay into a JISA at a time is £10.
If your child has both a stocks and shares junior ISA and a cash junior ISA, the £9,000 annual allowance is shared between both accounts.

Our Junior ISA invests in stocks and shares. The value is therefore likely to go up and down over time.
This is normal for this type on investment, but it means there is a risk your child could get back less than has been paid in if they withdraw at a time when the value is lower.
