Product
Accounts are able to participate but cannot exceed the annual ISA subscription limit. If it were to exceed the subscription limit, the shares should be transferred to a non-ISA account.
They can be transferred to your linked General Investment Account that is created when opening an MEXEM Stocks & Shares ISA account.
Margin trading is not permitted within a Stocks and Shares ISA.
HMRC rules require that all investments held within an ISA must be fully paid for using available cash in the account. Borrowing to invest (also known as leverage or margin) is not allowed under ISA regulations.
This ensures your ISA remains compliant with the UK’s tax-free savings rules.
For the 2025/26 tax year, the Junior ISA annual allowance is £9,000.
This limit applies across all Junior ISAs your child may hold, including both cash and stocks & shares accounts.
Parent or legal guardian:
Opens the account and acts as the registered contact.
Ownership:
All contributions belong to the child.
Access:
Funds remain locked until the child turns 18, at which point the Junior ISA automatically converts into an adult Stocks & Shares ISA.
A Junior ISA (JISA) is a tax-free savings and investment account designed to help you build a secure financial future for your child. Any money you invest grows free from Income Tax and Capital Gains Tax, making it one of the most efficient ways to save for their future.
There are two types of Junior ISAs available in the UK:
Junior Cash ISA – earns tax-free interest.
Junior Stocks & Shares ISA – lets you invest in a wide range of qualifying investments such as shares, ETFs, funds, and bonds.
At MEXEM, we will soon offer a Junior Stocks & Shares ISA that gives you access to 150+ global markets, 33 countries, and 23 currencies, all through our powerful trading platforms.
