Junior Stocks and Shares ISA

A Junior ISA is a tax-efficient way to save and invest on behalf of your child.

Payments into a Junior ISA are different from adult ISAs, because the money you put in belongs to your child. Once you put money in, you can’t take it out again, except in exceptional circumstances, and your child can only get access to their money when they turn 18.

There are two types of Junior ISA:

• Junior Cash ISAs: earn interest like a savings account. The interest rate is fixed and typically based on the rate set by the Bank of England.
• Junior Stocks & Shares ISAs: (Also known as Junior Investment ISAs), these invest in financial markets with the aim of earning returns for investors that are greater than those you would get in a Junior Cash ISA. Returns are not guaranteed, and the value of your investments can go down as well as up.

Your child can have one or both types of Junior ISA and you can deposit up to the annual limit of £9,000 into them in any combination you like.

For example, you could pay £3,000 into a Junior Cash ISA and up to £6,000 into a Junior Stocks and Shares ISA, or vice versa. You can split the allowance however you want to between the two accounts.

The benefit of a Junior ISA is that you or your child won’t pay tax on any interest, returns or dividends they receive.  

Wealthify only offers a Junior Stocks and Shares ISA.  Any money paid into a Junior ISA will belong to the child, but they cannot access it until their 18^th birthday.

Junior ISAs allow your child to keep more of their money by protecting any positive returns they receive from income tax and capital gains tax.

Only a child’s parent or legal guardian can open a Junior ISA account on their behalf.

Your child can have one Junior Cash ISA and/or a Junior Stocks and Shares ISA at any time, into which you can currently contribute a maximum of £9,000 per tax year, per eligible child. You can split the amount however you choose between a Junior Cash ISA and a Junior Stocks and Shares ISA as long as the combined amount doesn’t exceed the annual limit.

You don’t need to use the same provider for your child’s Junior Cash ISA and Junior Stocks and Shares ISA, so you’ve got flexibility to choose the best option for you and your child.

At the start of each new tax year, on 6 April, the child’s annual Junior ISA allowance re-sets and you can start another year of tax-efficient saving for each child.

Your child will only be able to access the money within their Junior ISA when they turn 18.

When they turn 18, the Junior ISA is automatically changed into an adult ISA. At this point, they can choose to keep saving or investing, or they can withdraw some or all of the balance to help pay for things like university, or a new car.

If you want to build an investment pot for your child that neither you or they can touch until your child turns 18, then a Junior ISA could be the answer. Any money paid into a Junior ISA belongs to the child and cannot be withdrawn by anyone other than the child when they turn 18.  

Junior ISAs are available to children who:

• Are under the age of 18
• Are residents of the UK, or are dependants of a crown employee (e.g. army employee based overseas)
• And don’t already have a Child Trust Fund (CTF).

You can transfer your Child Trust Fund over to a Wealthify Junior ISA, but your child cannot have a CTF and a Junior ISA at the same time. When transferring a CTF to a Junior ISA, the full balance must be transferred.   

Junior ISAs can only be opened by the parent or legal guardian of a child under the age of 18 who fits the eligibility criteria. Once opened the parent/guardian will become the registered contact for the account.

As the registered contact for a Junior ISA, you are the only person authorised to make decisions about the management of the account. You’ll also need to keep Wealthify informed if the child’s personal details change; e.g. if they change their name, address, contact number, or get married. 

When the child turns 18, they will become the registered contact and their Wealthify Junior ISA will change into an adult ISA. They can either keep investing, move it somewhere else, or withdraw some or all of it e.g. to help pay for university, or a car.

The money in a Junior ISA will never belong to the parent/guardian. It belongs to the child, but they won’t be able to access it until their 18^th birthday.

The following initial minimum deposits apply to each of our investment products.

Yes, you can invite anyone to be a contributor. That could be your parents, siblings, cousins, friends, neighbours… the list goes on. Once they’ve accepted the invite, and passed verification, they’ll be able to add to your child’s ISA whenever they want.

The only caveat to this is that they’ll need to live in the UK and be a UK tax resident, aged over 18.

You can invite someone to pay into your Wealthify Junior ISA by using our 'Friends and Family' feature. You can find out more about this here: Junior ISA family friends.

Money added to a Junior ISA belongs to the child. The parent or guardian who opened the Junior ISA acts as the registered contact, but they can’t access the money once it has been deposited, unless there are exceptional circumstances. When the child turns 18, account ownership is transferred to them.
