what is a junior isa and how do they work Junior ISAs were first introduced in November 2011 and provided a replacement to the short-lived Child Trust Fund.

The Junior ISA celebrates its 8-year anniversary on 1st November 2019 and based on the maximum contribution limits, had you opened an account back in November 2011, you could have saved £31,552 of tax-free cash. This, however, could have been slightly more or less based on the type of Junior ISA you opened.

What is a Junior ISA

A Junior ISA is a tax-efficient way of building a savings pot for your child. There are two types of Junior ISAs, a Junior Cash ISA or a Junior Stocks and Shares ISA. The lump-sum accrued over time can be accessed by your child at the age of 18.

Junior ISA features:

  • In the 2019/20 tax year, a maximum of £4,368 per child can be invested in a Junior ISA and rises to £9,000 in 2020/21 (any unused allowance cannot be carried forward)
  • A Junior ISA can only be opened by parents or legal guardians of the child
  • Anybody can contribute to a Junior ISA once it is opened
  • A child can have both a cash Junior ISA and a Stocks and Shares Junior ISA but the annual allowance must be spread between the two accounts
  • Once your child turns 18 they can access the money or they can transfer it into an adult ISA
