What Is A Junior Stocks & Shares ISA (JISA)?

A junior stocks and shares ISAs is an investment account for your children where you can invest up to £9,000 a year. Profits from JISAs are tax-free and can only be accessed by your child when they turn 18.

Junior ISAs are based on the same principle as its adult peers. It’s a government-sponsored tax-free savings vehicle, within which up to a predetermined sum of money can be invested and not be subject to income or capital gains taxes while it remains in the shelter.

It is important to note that, unlike an adult investment ISA, you can only have one junior investment ISA account rather than multiple plans with different providers. However, you can transfer funds between providers.

Junior stocks and shares ISAs offer better potential returns than cash ISAs as they are investment accounts rather than savings accounts. However, it’s important to remember that the stock market can go up as well as down.

Pros & Cons Of Junior Stocks & Shares ISAs (JISAs)

Fun fact: The majority of junior ISAs at Hargreaves Lansdown still have money invested a year later, and almost four in five remain with it to the age of 24.

Pros

  • Tax-free-profits: Any profits made in a Junior Investment ISA over its 18-year term are completely tax-free, offering a huge advantage over standard accounts. That would be very difficult to achieve outside of the vehicle
  • Money for MilestonesJISAs are designed for saving to give kids a lump sum at 18, perfect for university, a car, or other big goals. Funds stay locked until then, so there’s no early temptation
  • Better potential returns: JISAs offer more investment flexibility than savings accounts, making them ideal for long-term capital growth

Cons

  • Poor performance: JISA investments can go down as well as up, so there’s a chance of losing money instead of growing it
  • Account fees: Unlike cash ISAs, Junior Investment ISAs come with account fees, which can eat into returns
  • Money locked away: Money in the JISA stays locked until the child turns 18, so you can’t access it in case of emergencies

How Much Could A JISA Be Worth At 18?

Hargreaves Lansdown (which offers a free JISA) recently calculated that by investing as little £25 a month for 18 years this could result in a JISA of £10,831, assuming an annual return of 7%. This would be a huge boost for when your child goes to university, travels the world on a gap year, or starts full-time work.

Junior Stocks & Shares ISA Fees

Here’s a quick breakdown of the main fees you’ll encounter and how much of an impact they will have on your children’s investments:

Account fees

This is how much an investment platform will charge to hold your investments in a JISA. At the moment, Hargreaves Lansdown is the cheapest investment JISA as they do not charge an account fee. Some providers, like Wealthify, charge quite a lot for a JISA. Their JISA fees are 0.75%, which means if you put in £10,000, you will be charged £75 a year for the account.

Dealing charges

This is the fee for every time you buy and sell investments. Again HL’s JISA does not have dealing charges, but others like ii give you one free trade a month. Otherwise it can cost as much as £3.99 when you add investments.

Other charges

  • Exit fees: a penalty some investment providers levy for leaving their platform (you should avoid these companies)
  • Phone dealing charges: Some firms like AJ Bell charge an additional fee for buying and selling investments over the phone
  • Withdrawal charges: for some times of withdrawals (like CHAPS payments) investment providers can charge an additional admin fee.

What Can You Invest In Through A Junior Stocks & Shares ISA?

Unlike a cash ISA, the junior investment ISA has much more freedom to invest and indeed it’s specifically designed to allow parents to invest in:

  • Stocks and shares
  • Managed funds
  • ETFs
  • Bonds
  • Gilts
  • Pre-made portfolios

The full list of instruments you can invest in on behalf of your child or loved one will vary from provider to provider. It’s definitely worth checking out what is and isn’t permissible with a particular manager before you apply for a Junior Investment ISA. That helps ensure the type of investments you have in mind are covered by that provider.

For example, Hargreaves Lansdown offers Junior Investment ISA accounts access to 3000 funds, UK and overseas shares and a range of investment trusts and ETFs. Whilst Nutmeg is more suitable for those not confident enough to pick their own investments by offering Junior Investment ISA accounts a choice of pre-built managed funds with varying risk profiles to invest in.

Which is better – a junior cash ISA or a junior stocks and shares ISA?

A stocks and shares junior ISA can provide better returns.

There are almost one million children’s ISAs in the UK, and only around  30% of them are invested in the stock market as opposed to 70% which are invested in cash savings accounts.

Historically the stock market has provided much better returns that cash savings accounts, but there are risks involved. Here are the key differences between cash and investment junior ISAs.

With a junior cash ISA money is held in a savings account and you receive interest. With a Junior stocks and shares ISA your money is invested in the stock market. This can result in better returns, but also comes with risk and you may get less back than you put in if the market underperforms.

Personally, the three junior ISAs I have for my children and main invested in the stock market, as these are longer-term investments over five years and I’m prepared to take on the risk of the market dips.

Ultimately, though, the stock market can go down, so with a cash JISA you are guaranteed to get back at least what you put in. If your money is invested in the stock market you can get back less than you originally invested.

JISA Alternatives:

There are a few alternative ways to invest for your children as opposed to junior stocks and shares ISAs including:

  • GIA: a general investment account lets you invest as much as you want, and funds can be withdrawn at any time – although there are no tax benefits
  • Junior SIPP: if you want to invest some money for when your children return because you are worried about them wasting it when they turn 18, you can open a junior SIPP (self-invested personal pension). Here your children can only access the money when they hit retirement age. There are also considerable tax benefits
  • Cash ISA: If you are worried about the stock market going down and your children’s investments potentially losing money, there are some very good interest rates in savings accounts for cash ISAs at the moment. Although there is a limit on the tax free benefits.

Junior ISA Allowance (2025)

The annual Junior ISA allowance for the 2025/26 tax year is £9,000. This is the total amount that can be contributed across both Junior Stocks & Shares ISAs and Junior Cash ISAs combined.

The allowance can be split between the two types in any proportion, for example, £6,000 into a Stocks & Shares ISA and £3,000 into a Junior Cash ISA.

However, a child can only hold one active Junior Cash ISA and one active Junior Stocks & Shares ISA at any one time. Funds can be transferred between providers or from one type to another without using up the allowance.

It’s also important to note that the allowance cannot be rolled over. If it’s not used during the tax year (ending 5 April), it is lost.

What About Child Trust Funds (CTFs)?

Children born between 1 September 2002 and 2 January 2011 may already have a Child Trust Fund (CTF). A child cannot hold both a CTF and a Junior ISA simultaneously.

However, CTFs can be transferred to Junior ISAs—a move many parents choose to make because Junior ISAs often offer better investment choices, lower fees, or higher interest rates.

The transfer must be done in full; partial transfers are not allowed. Once transferred, the CTF is permanently closed, and the Junior ISA becomes the child’s tax-free savings wrapper going forward.

Junior Stocks & Shares ISA FAQs:

Yes. The FSCS or Financial Services Compensation Scheme was set up by Parliament and is funded by the financial services industry. It can compensate eligible investors in the event of fraud or insolvency. Under current legislation, the scheme can pay out up to £85,000 for savings accounts and £50,000 on investment accounts. A junior investment ISA would fall into the latter category, so in the event of the provider of the ISA or the custodian of the assets becoming insolvent, the FSCS would step in.

The implicit guarantee provided by the fund and the tax-free benefits of the shelter certainly helps to make the junior socks and shares ISA an attractive proposition when considering investment for the next generation.

It’s important to remember that past performance is not an indication of how well a stock and shares ISA account will do in the future. One way to ensure you get the right performance for you is by using a DIY JISA where you pick and choose exactly what investments you want for your children.
