What is a junior ISA (JISA)?

A OneFamily Junior ISA (JISA) is an investment account for children under the age of 16. It can be opened by the child's parent or legal guardian but anyone can pay money in. The child will be able to access it when they turn 18 without paying tax on any money they withdraw.

OneFamily’s Junior ISA is an investment JISA. That means the money that you pay in is invested on your behalf. It therefore has good potential to outgrow inflation, but the value is likely to go up and down over time. If the child withdraws money when the value is low, they could get back less than has been paid in.

That’s why at OneFamily, we give you a simple choice of three funds so you can choose the risk level you're comfortable with.

Our minimum investment is just £10 a month by direct debit or a lump sum starting from £100.
