Important information - investment value can go up or down and you could get back less than you invest. If you're in any doubt about the suitability of a Stocks & Shares ISA, you should seek independent financial advice. The tax treatment of this product depends on your individual circumstances and may change in future. If you are uncertain about the tax treatment of the product you should contact HMRC or seek independent tax advice.

What is a Junior Stocks and Shares ISA?

A Junior Stocks and Shares ISA, also known as a JISA, is a tax-efficient savings and investment account for under 18s. 

Junior ISAs can only be opened by the child's parent or guardian, but anyone can pay into it after that. It is the parent or guardian’s responsibility to manage the funds in the account on the child’s behalf. 

A Junior Stocks and Shares ISA could give you better returns than cash savings – but this is not guaranteed. If you are unsure about whether you should invest, then seek independent advice.
