Investing with a Junior ISA

A Junior ISA, or a junior individual savings account, is a tax-efficient wrapper that allows parents, grandparents and family friends to save into cash and/or invest on behalf of a child.

Junior ISAs must be opened by a parent or guardian but are held in the child’s name. The person opening the Junior ISA will be making all the decisions about where to invest until the child reaches 16, at which point the child can choose to become involved.

The money cannot be accessed by anyone until the child’s 18th birthday, at which point the Junior ISA becomes a standard ISA, the property of the child and fully accessible.

Who is eligible?

A Junior ISA is available to any child who is a resident in the UK. If a child already has a Child Trust Fund (CTF), it can be transferred into a Junior ISA.

Child Trust Funds were the previous long-term tax-efficient accounts designed to help parents save. They have now been superseded by Junior ISAs and it is no longer possible to open a CTF, although if you already have one you can continue to contribute.

How much can you invest?

The current annual limit to invest into a Junior ISA is £9,000*. You can contribute an annual lump sum; regular, monthly savings; or ad hoc payments.

Contributions can either be made into a cash account or a stocks and shares account, where they would be invested into assets like funds, individual stocks and bonds. Because of the potential long-term nature of the Junior ISA (up to 18 years), investing could be an excellent way to significantly boost your returns, as the two examples below show:

  • £50 a month saved into a cash account with an interest rate of 2.5% over 18 years would give your child £13,650 on their 18th birthday¹
  • £50 a month invested with an average rate of return of 6% over 18 years would give your child £19,465 on their 18th birthday².

Note that the total annual limit is £9,000* across both cash and stocks and shares accounts (not £9,000* for each account).

How can you open a Junior ISA?

Cash Junior ISAs can be opened via most major banks or building societies. Be sure to shop around for a good rate and be aware of any temporary interest bonuses.

Stocks and shares Junior ISAs can be purchased through a funds supermarket platform, a broker, an advisor or direct from a fund provider. Some are also available at major banks.

You’re not locked in to your existing Junior ISA provider. For example, if you have a cash savings account and you find a provider with a better rate, you can move the money. You can also change the funds or other assets in which you are invested or change from cash to stocks and shares and back again.

You can invest in a Junior ISA online, by phone and by post. Charges and options may vary.

What should you invest in?

Choosing a Junior ISA cash account can be fairly simple. The main considerations are the interest rate paid and the length of time the interest rate is valid.

Choosing investments for your Junior ISA stocks and shares account can be tougher, but getting it right (or wrong!) can have a huge impact on the value of your investment.

However, the knowledge that professional analysts have analysed a fund or trust in depth before assigning them a rating can be a valuable additional filter for anyone looking to make their own decisions. Past performance is not a reliable guide to future returns. Market and exchange-rate movements may cause the value of investments to go down as well as up. Yields will fluctuate and so income from investments is variable and not guaranteed. You may not get back the amount originally invested. Tax treatment depends of your individual circumstances and may be subject to change in the future. If you are unsure about the suitability of any investment you should seek professional advice.
