What is a junior ISA?
A junior ISA is an individual savings account specifically for anyone in the UK who is under 18. A junior ISA works in the same way as a normal ISA, as it is a tax-free savings account with a limit of how much can be saved in it each year. The allowance is slightly different for a junior ISA at £9,000 compared with £20,000.
Parents or legal guardians can pay into a junior ISA, and when the child turns 18 it automatically converts to an adult ISA. This retains its tax-free status as well as any interest you’ve built up throughout the years. On the child’s 18th birthday the money can then be accessed by them and spent as they wish.
The junior ISA allowance is currently £9,000."
Why should I open a junior ISA for my child?
A junior ISA is a great way to start saving money for your child’s future. The money is locked away until they turn 18, so view this account as a long-term saving plan. Therefore, it could be used as a way to pay for university or a deposit for their first house.
However, the fact they can't access the money until they turn 18 might mean it isn't suitable for your child. The good news is there are other children's savings accounts available.

The pros and cons of junior ISAs
Pros
Cons
Types of junior ISA explained
There are two types of junior ISAs available for you to choose from. Bear in mind that you can only open one junior cash ISA and one junior stocks and shares ISA each year.
1. Junior cash ISAs
These are cash-based deposit savings accounts. Any money you save for your child is protected against dropping in value. In comparison to the junior stocks and shares ISA, this offers variable interest rates. Your child's money will always grow in value as long as the interest rate is above 0%.
2. Junior stocks and shares ISA
This offers the potential for a greater return, but your child's money could also fall in value, so there is some risk attached. It also doesn’t offer variable or fixed interest rates. Instead, it offers you a return based on current stock market performance.
How do I set up a junior ISA account?
You can open a junior ISA account with your bank, building society or via an investment platform, but the best way to ensure you are getting the top rate is to compare deals from different providers.
It's a good idea to open a junior ISA for your child as soon as you can, as the earlier you start to save for your child, the longer the money has to grow.

Junior ISAs FAQs
How does Uswitch choose its editor’s picks?
We know that the best savings accounts are always changing, so the editorial team at Uswitch regularly checks the rates on this page and updates them at least fortnightly. To find the best deals we compare products by taking various factors into consideration, including the interest rate (AER), the balance needed to get the highest interest rate, minimum initial deposit, withdrawal conditions, and the term of the account. These factors change subject to the category of account.
We use this system for the whole of the market covering nearly all account providers, so you can get an overview of what is available and compare savings accounts in the UK. All the banks featured are FSCS protected, so you can be reassured that your money is safe, provided it’s within the defined limits and regulations. To find out more about how FSCS looks after your money, visit fscs.org.uk.
Can I withdraw money from my child’s junior ISA?
Unfortunately not. The account will not be accessible until your child turns 18 and then it becomes a standard ISA in their name and the money can be withdrawn.
Can I save for more than one child in a single junior ISA?
You can only open a junior ISA on behalf of one child.
Can I open a junior ISA for one of my friend’s children?
No, only a parent or legal guardian can open a junior ISA on behalf of their child. However, anyone can pay into a junior ISA if they wish to contribute to your child's future.
What is the difference between a junior ISA and Child Trust Fund?
All children born between September 2002 and January 2011 had a Child Trust Fund (CTF) opened for them on their behalf with £250 added by the government. A CTF works differently from an ISA as the allowance runs from the child’s birthday to the next, rather than the tax year. The fees were also higher and the government topped up the parental contribution in a CTF, but they don’t do this for an ISA.
Can I have a junior ISA and a Child Trust Fund?
You can’t have both for your child, so if you would like an ISA instead you’ll need to transfer the existing CTF. In general, a junior ISA offers greater flexibility and there are lower charges.
Can I have more than one junior ISA in a year?
You are only allowed to open one junior cash ISA and one junior stocks and shares ISA each year.
