Why fees matter.

Not all Junior ISAs are created equal. Over 18 years, fees add up.
IG’s commission-free investing and no account fees make a huge difference to your child’s portfolio.

FAQs

Your questions, answered.

Who can open a Junior ISA?

An IG Junior ISA (JISA) can be opened by a parent or legal guardian for a child under 14 who is a UK resident.

Is there a minimum monthly or lump sum contribution?

No, there’s no minimum monthly or lump sum requirement to open a Junior ISA with IG. You have complete flexibility to invest as much, as often as you want, up to £9,000 per year, tax-free.

Can I change or stop contributions at any time?

Absolutely. Contributions are flexible, meaning you can increase, decrease, pause, or stop them whenever you need.

Can I withdraw money from a Junior ISA?

No, a Junior ISA is locked until the child turns 18. This ensures the money stays invested for their future.

What happens to a Junior ISA when my child turns 18? 

When your child turns 18, the Junior ISA automatically becomes an adult ISA in their name. They then have full control over the account and can withdraw or continue investing as they choose.
