JISA rules

Annual ISA allowance

For the tax year 6 April 2024 - 5 April 2025, your allowance is £9,000

You can choose how to split your annual allowance as you wish. For example, all cash, or all stocks and shares, or split between the two.

  • Individual Savings Accounts (ISAs) were introduced in 1999 to replace old-style tax free savings. They allow you to invest up to a set allowance each tax year (6 April to 5 April) on which you will pay no tax on any interest you earn. A JISA is a type of ISA available to eligible children. There are two types of JISA – Cash and Stocks and Shares. You can hold one of each type until the age of 18. Once you have invested the full subscription for the year, you cannot make additional investments. The current annual ISA allowance is shown above.
  • Your yearly allowance does not roll over, so if you do not use it, it will not be added to the next year’s allowance. If you pay in to the account up to the maximum allowance, you cannot pay any more in, your allowance has been used up.
  • A JISA may only be held by an investor in his or her sole name. Joint accounts are not allowed. You must be under 18 years of age to invest in a JISA.
  • All JISA investments will be and must remain in the beneficial ownership of the child. Any rights in respect of your JISA may not be assigned and those rights may not be used as security for a loan.
  • All subscriptions to the JISA are a gift to the child, and as such cannot be repaid to the subscriber if at a later date the subscriber changes their mind.
  • A JISA may not be transferred from one investor to another.
  • The start of the JISA is the date of the first deposit.
  • On the instructions of the registered contact a JISA with all rights and obligations shall be transferred to another ISA manager within five working days.
  • You must not subscribe more than the overall subscription amount in total to a Cash JISA and Stocks and Shares JISA in the same tax year. Once the limit has been reached for the tax year you cannot make further subscriptions.
  • In the event of death of the child, the JISA must cease on the date of death. Interest will be paid gross up to the date of closure. Interest arising after the date of death will be subject to deduction of income tax at the appropriate rate and should be declared to HMRC as part of the deceased tax liabilities.
  • For a period of 30 days after opening the JISA the registered contact may instruct us that they have changed their mind and we will return the deposit to the child, subject to cheque clearance, with any accrued interest. The 30 day cancellation period starts on the day you open your Cash ISA and ends at close of business on the 30th calendar day. To cancel the JISA you can either visit or write to your local branch, enclosing your passbook. No administration charges will be made.
