What is a Junior ISA?
A Junior ISA (Individual Savings Account) is a long-term savings or investment account opened by a parent or legal guardian to save for their child’s future. It comes with tax benefits, which means any interest earned or growth in value is free from UK Income Tax and Capital Gains Tax.
The account is held in the child’s name but managed by the parent or guardian until they turn 18* (*Or at age 16 if the child chooses to become the registered contact on the account).
When they turn 18, the funds become fully accessible, and the child can use the money however they choose, for example, to help cover university costs, save for a first home, or continue growing their savings.
What types of Junior ISA are available?
There are two types of Junior ISA to choose from. You can have one cash Junior ISA and one stocks and shares Junior ISA for a child, but the annual contribution limit applies across both accounts combined.
- Cash Junior ISA: Works like a standard savings account, where money is kept as cash and earns tax-free interest.
- Stocks and shares Junior ISA*: Any money deposited is invested in the stock market, offering the potential for higher growth over time, but with the risk that the value of your investments can go down as well as up.
*Capital at risk.
What's the difference between a cash Junior ISA and a stocks and shares Junior ISA?
When choosing a Junior ISA for your child, it’s important to understand the differences between a cash Junior ISA and a stocks and shares junior ISA to make sure you're saving in a way that suits you and your family.
The table below highlights the main features, risks, and benefits of each type to help you decide which option best suits your savings goals.
| Feature | Cash Junior ISA | Stocks and shares Junior ISA |
| Risk | Low: your capital is safe, although the interest earned may not always keep up with rising prices (inflation) | Medium: the value of your investment can go down as well as up |
| Potential returns | Limited to the interest rate offered by the bank | Potential for higher long-term growth depending on market performance |
| Tax benefits | Interest is tax-free | Any investment growth is tax-free |
| Access | Locked until age 18 | Locked until age 18 |
| May suit | Parents who want safety and certainty | Parents aiming for the potential of higher long-term growth and comfortable with the level of risk |
| Contribution limit | £9,000 per tax year across both Junior ISA types combined | £9,000 per tax year across both Junior ISA types combined |
Note: You can transfer a Junior ISA between providers, or move between a cash Junior ISA and a stocks and shares Junior ISA. Some parents transfer to seek greater growth potential, while others prefer the certainty of cash.
Junior ISA vs Child Trust Fund
If your child was born between 1 September 2002 and 2 January 2011, they may have a Child Trust Fund (CTF) in their name. Child Trust Funds are no longer available to open, and Junior ISAs (JISAs) have largely taken their place as the main tax-free savings and investment option for children.
Here's a comparison of how the two accounts differ:
| Feature | Child Trust Fund | Junior ISA |
| Open to new accounts | No, closed to new applicants | Yes |
| Who can hold one | Children born between Sept 2002 and Jan 2011 | Any child under 18, UK resident |
| Tax benefits | Tax-free interest or investment growth | Tax-free interest or investment growth |
| Access to funds | Not available until the child turns 18 | Not available until the child turns 18 |
| Can a child hold both CTF and Junior ISA at once | No | No |
| Contribution allowance | Up to £9,000 birthday to birthday | Up to £9,000 per tax year |
A child cannot hold a Child Trust Fund and a Junior ISA at the same time. If your child has a Child Trust Fund, you have the option to transfer it into a Junior ISA using the new provider's transfer process. Once the transfer is complete, the Child Trust Fund will close and future contributions can be made to the Junior ISA instead.
Who can open a Junior ISA?
A Junior ISA can only be opened by a parent or legal guardian of the child. This person becomes the "registered contact" and is responsible for managing the account until the child turns 18. To be eligible for a Junior ISA, the child must:
- Be under 18 years old
- Be a UK resident (or the dependent of a Crown servant)
- Not already have a Child Trust Fund (CTF) or Junior ISA of the same type (although you can transfer an existing CTF or switch Junior ISA providers)
Anyone can contribute to the Junior ISA once it's open, up to the £9,000 annual allowance.
How much can you save in a Junior ISA?
You can contribute up to £9,000 per tax year across all Junior ISAs held in a child’s name. This is the total amount that can be contributed, regardless of who makes the payments.
A few things worth knowing:
The allowance resets each tax year: The tax year runs from April 6 to April 5, and any unused allowance doesn't carry over. The £9,000 allowance then resets, and any new contributions count towards the new tax year allowance.
Transferring a Child Trust Fund doesn’t count towards the limit: If you're transferring an existing Child Trust Fund into a Junior ISA, that transfer doesn't use up any of the £9,000 Junior ISA allowance†. Only new contributions made into the Junior ISA after the transfer will count.
The money belongs to the child: Regardless of who contributes, the savings belong to the child, and they can't access the funds until they turn 18.
†Transferring a Junior ISA does not affect the annual Junior ISA allowance. Any contributions already made during the tax year will count towards the £9,000 limit, so the remaining allowance stays the same after the transfer.
Exemptions to Junior ISAs: Access, transfers, and special circumstances
While Junior ISAs are designed to be long-term savings accounts, there are a few exemptions where withdrawals or special arrangements are allowed:
Transfers between providers: While not a withdrawal, you can move a Junior ISA from one provider to another.
Child Trust Fund transfers: Existing Child Trust Funds can be transferred into a Junior ISA, which does not count as a new contribution and won’t impact the Junior ISA allowance.
Child’s death or terminal illness: Special provisions apply in these circumstances. If this affects you, we will provide support and guidance throughout the process.
What are the benefits of a Junior ISA?
A Junior ISA offers several advantages for parents and guardians looking to save for their child’s future:
Tax-free growth: Any investment growth is tax-free.
Long-term savings: The money is locked away until the child turns 18, helping you build a financial head start for them.
Ownership by the child: The account is held in the child's name, and only they can access the funds once they turn 18 (special exemptions apply).
Choice of accounts: You can choose between a cash Junior ISA for stability, or a stocks and shares Junior ISA for the potential of higher long-term growth (capital at risk).

Is a Junior ISA right for my child?
A Junior ISA can be a great way to save or invest for your child’s future, but it may not suit every family. Consider opening one if you:
- Hope to build your child’s savings in a tax-smart way.
- Understand that the funds can only be accessed by your child once they reach 18.
- Wish to involve family and friends in contributing to your child’s savings.
- You may need access to the funds in the future.
- Prefer a more flexible short-term savings option.
If you are unsure if a Junior ISA is right for your family, it may be worth seeking independent financial advice. You can find regulated advisers at unbiased.co.uk, but advice may come with a fee.

Frequently Asked Questions
No. Money held in a Junior ISA cannot normally be withdrawn until the child turns 18 and takes control of the account. In exceptional circumstances, such as a child's terminal illness or death, earlier access to the funds may be possible. If you are affected by either of these situations, please contact us and we will be here to support you.
Yes. Junior ISAs can be transferred between providers at any time. Using the official transfer process ensures the funds stay within a Junior ISA and the move doesn’t count towards the annual Junior ISA allowance.
A child can hold one Junior cash ISA and one Junior stocks and shares ISA at the same time. However, the £9,000 annual allowance is shared between the two, so contributions across both accounts can't exceed this combined limit in a tax year.
No. While 16 and 17 year olds can hold and manage their own Junior ISAs, they can’t open an adult ISA, including a Lifetime ISA, until they are 18.
No, contributions aren't required each year. You're free to contribute when it suits you, whether that's regularly or as a one-off payment.
If you don't use the full £9,000 Junior ISA allowance in a tax year, any unused amount will be lost. However, the allowance resets each tax year, giving you a fresh £9,000 allowance.
When your child turns 18, they gain full access to the money and take control of the account. Some providers will automatically convert the Junior ISA into an adult ISA product, while others may wait for your child to confirm how they would like the account to be managed going forward.
Unity Mutual will write out to you and your child in the weeks before their 18th birthday to make them aware of their options. If we don't receive an instruction, we'll mature the Junior ISA into our Stocks and Shares Flexible ISA, which is invested in the same fund.
A grandparent can't open a Junior ISA on a grandchild's behalf, but they can contribute money to the account, subject to the £9,000 annual Junior ISA allowance.
Opening the account, and any ongoing decisions about it, are the responsibility of the child's parent or legal guardian.
