How it works

Easy to set up

Parents or legal guardians can set up a regular Direct Debit from £10 per month or pay in a lump sum of £100 or more. Or transfer in from an existing Junior ISA or Child Trust Fund.

Anyone can pay in

Once the account’s open, anyone can contribute by Direct Debit, bank transfer or cheque.

You can invest up to £9,000 per tax year.

Available when they turn 18

The child named on the account can access their tax-efficient lump sum at the start of their adult life, at 18 years old.

Important information

Please bear in mind the value of stocks and shares can fall as well as rise and the child could get back less than has been paid in.

The tax advantages of Junior ISA depend on you and your child's individual circumstances and the tax treatment of Junior ISAs may change in the future.

There’s an annual management charge of 1.5%.

Only the child can access the money and only after they turn 18.

Is this the account for you?

Our Junior ISA may be right for you if:

  • You’re putting money away for a child for 10 years or more

  • You want to invest in stocks and shares for potentially higher returns

  • You want to open with a regular Direct Debit from as little as £10 per month or a lump sum of £100 or more

Our Junior ISA may not be right for you if:

  • You want your child to have access to the money before the age of 18

  • You want a guaranteed return on your investment

  • The Post Office Junior ISA is a stocks and shares Junior ISA provided by OneFamily. It’s one of two types of Junior ISA available on the market.

    • Cash Junior ISA: like a bank or building society savings account, except your child won’t pay tax on the interest they earn on their savings
    • Junior stocks and shares ISA: investments are made in stocks and shares on the financial markets, in a variety of ways. Effectively the money invested will be put into things like businesses, equities (shares) and commodities (products, such as coffee)

    An eligible child can have one or both types of ISA. But they can hold no more than one cash account and one stocks and shares account at any one time.

    Please note: Post Office and OneFamily cannot provide advice on this product. If you’re not sure if it suits you, please get independent financial advice.

  • A Post Office Junior ISA can only be opened.

    • by someone aged 16 or over.
    • for an eligible child aged under 16.
    • if you have parental responsibility for them.

    The person who opens the account will be the ‘Registered Contact’. They are the only person instructions will be accepted from.

    When the child turns 16, they can decide if they want to become the Registered Contact of the account.

  • Anyone can pay into a Junior ISA if the total doesn’t exceed the tax-free allowance each year. For example, if you’re a parent investing for your son or daughter, grandparents, uncles and aunts and friends can all make deposits after the account’s been opened.

  • The child named on the account will be able to access the money invested for them once they’re 18 years old.

  • The Post Office Junior ISA is invested in the Family Balanced International Fund. This is a sub-fund of an ICVC.

    The fund aims to achieve long-term growth. It does this by investing mainly in UK and overseas shares, along with fixed interest investments.

    What is an ICVC?

    ICVC stands for Investment Company with Variable Capital. It’s a type of company or fund created to invest in other companies and other investments.

    ICVCs usually have one or more sub-funds in which investors can buy shares to create a pool of money. This pool is then managed by an experienced investment advisor on their behalf. These experts use the money to buy investments such as stocks and shares. By doing this, an individual's money can be invested across a wide range of assets, helping spread the risks associated with investing in stock market linked investments.

    Remember, the value of stocks and shares can fall as well as rise. The child could get back less than has been paid in.
