Always remember that investments can go down as well as up in value, so your child could get back less than you put in. Money in a Junior ISA belongs to the child, not the parent, and can only be accessed when the child turns 18. ISA rules apply, and tax rules can change.

What Is a Junior ISA?

A Junior ISA is a tax-free savings or investment account for children under the age of 18 residing in the UK.

The Junior ISA allowance for this tax year is £9,000, and both friends and family can pay into the ISA on behalf of the child. Children aged between 16 and 18 can hold both a junior and a standard Cash ISA.

Junior ISA Rules

The following are the Junior ISA rules:

  1. Your child must be a UK resident and younger than 18 years old.
  2. If your child does not live in the UK, you must be a Crown servant (for example, in diplomatic or overseas civil service), and they must depend on you for care.
  3. At all times, the money in a Junior ISA belongs to the child, and it cannot be withdrawn by anyone except your child once they turn 18.

How Does a Junior ISA Work?

When a parent or guardian opens a Junior ISA, they can invest up to £9,000 for that tax year in regular monthly payments or by a lump sum at any time.

They can also encourage family members such as grandparents, aunties, uncles and even friends to contribute up to the total allowance. These funds may accumulate interest and returns that do not count towards the allowance and are effectively tax-free.

When your child turns 18, they can withdraw the money or the Junior ISA rolls into a standard adult ISA.

Advantages of a Junior ISA

Here are some of the advantages of a Junior ISA:

  1. You can deposit up to £9,000 for your child, which doesn’t impact your own £20,000 ISA allowance. 
  2. Junior ISAs are tax-efficient. The income or investment returns generated by a Junior ISA do not count towards the £9,000 allowance, so all interest and gains are tax-free.
  3. Gifting money by depositing it in a Junior ISA can help reduce your inheritance tax bill.
  4. Family and friends can also contribute to the ISA, up to the £9,000 allowance.
  5. The money always belongs to the child, and they can only access it when they turn 18, which can be a significant boost when they reach adulthood.

Disadvantages of a Junior ISA

Here are some of the disadvantages of a Junior ISA:

  1. The main disadvantage of a Junior ISA is the inability to withdraw money until the child turns 18. If there are ever emergencies or expenses while the child is under 18, the savings cannot be accessed.
  2. When your child turns 18, they can spend the funds as they wish, which may not align with what you hoped the funds would go towards when you were saving.

  1. Bestinvest - Low cost; Lots of investment options; Beginner-friendly
  2. AJ Bell - Mid-price range; Lots of investment options

  6. Hargreaves Lansdown - Mid-price range; Lots of investment options

2. Who can open a Junior ISA?

The parents or guardians with legal responsibility for a child under 16 can open a Junior ISA and manage the account. A child aged 16 or 17 can open and manage their own Junior ISA as well as an adult Cash ISA. At all times, regardless of who opened the Junior ISA or who is managing the account, the savings belongs to the child, but they cannot withdraw any money until they turn 18.


3. Are Junior ISAs a good idea?

Yes, Junior ISAs are a good idea. A Junior ISA can be a great way to save long-term for your child and to provide them with the best financial start in life. You do not have to pay capital gains tax if the investment grows, and no UK income tax on any dividends or interest payments, which can help grow savings significantly. A Junior ISA is especially beneficial if you have exceeded the £20,000 allowance of your own ISAs and want to avoid any inheritance tax.


4. Can parents withdraw money from a Junior ISA?

A parent cannot withdraw money from a Junior ISA unless in the following circumstances:

  • The Junior ISA is being closed.
  • A terminal illness claim made on behalf of the child has been agreed upon.
  • To meet certain provider management charges. These will be set out in the terms of your management agreement.


5. Can a grandparent open a Junior ISA?

A grandparent can only open a Junior ISA if they are the legally responsible guardian for the child. Only a parent or a guardian with legal responsibility can open a Junior ISA. A grandparent can make contributions to a Junior ISA if they wish.


6. Does the government contribute to Junior ISAs?

No, the government does not contribute to Junior ISAs. Junior ISAs have replaced Child Trust Funds (CTF). When a parent opened a CTF, the government used to pay in £500. However, the drawbacks of Child Trust Funds were high investment charges and poor interest rates. A Junior ISA is now a comparably better option to save for your child, and if you have an existing CTF for a child under 18, you can transfer these savings to a Junior ISA.

7. How can a grandparent save for a grandchild?

A grandparent can pay into their grandchild’s Junior ISA set up by a parent or legal guardian. All they need is the account number of the Junior ISA they want to put money in and the child’s date of birth. All deposits must be made from a UK bank account and cannot exceed the £9,000 per year allowance.


8. How much can I put into a Junior ISA?

You can deposit as little or as much money as you want into a Junior ISA up to a maximum of £9,000 in one tax year. 


9. Can my child have two Junior ISAs?

Yes, your child can have two Junior ISAs in the form of a Junior Cash ISA and a Junior Stocks and Shares ISA. You must then split the £9,000 ISA allowance between both Junior ISAs in one tax year. You can only have one Junior Cash ISA and one Junior Stocks and Shares ISA open at any time. If your child is over the age of 16, they can hold both a Junior ISA and a standard Cash ISA.


10. Can I buy shares for my child in the UK?

Children under the age of 18 cannot hold company shares in their own name, but they can invest through a Junior Stocks and Shares ISA. Just like a regular adult ISA, the money deposited into the Junior ISA can be invested in equities, bonds, cash and even property shares, and you do not have to pay income tax or capital gains tax on any returns.
