If you want to give a child a financial leg-up — towards university, a first car, or simply a sensible start — a Junior ISA is one of the most efficient ways to do it. It is the children's version of an ISA, and it shares the same tax-free appeal.
How it works
A Junior ISA, or JISA, can be opened by a parent or guardian for any child under 18. Anyone can pay in — grandparents, family, friends — up to a generous annual limit. The money grows free of income tax and capital gains tax, and the child cannot touch it until they turn 18, when it becomes a normal adult ISA in their name.
Cash or stocks and shares?
- Cash JISA — safe and predictable, like a savings account.
- Stocks and shares JISA — invests the money for potential long-term growth.
Because the money is locked away for years, often a decade or more, time is firmly on your side. Over such a long horizon, an invested JISA has historically tended to outgrow cash, riding out the bumps along the way. The long lock-in is exactly the condition under which investing makes most sense.
The catch at 18
The one thing to be aware of is that at 18 the money becomes the child's, to do with as they please. There is no way to keep control beyond that point. For most families that is the whole idea, but it is worth a conversation as the child grows, so the pot is used wisely rather than spent in a weekend.
Getting started
Even small, regular contributions add up impressively over eighteen years thanks to compounding. Set up a modest monthly payment when a child is young, and you give them a genuinely valuable head start.
