What is a Junior ISA?

A Junior ISA (JISA or child ISA) is a tax-efficient account set up by a parent or guardian for children under the age of 18. The parent or guardian will contribute to the account but only the child can access the money – and only after they turn 18. 

At Nutmeg, you can only open a Junior ISA for a child who is under 16 years old, but it makes sense to open a Junior ISA from the day they are born. The full 18 years means they can benefit from compounding and afford to take more investment risk. And with tax-free returns, the money you invest has the potential for further growth.

Tax treatment depends on your individual circumstances and may be subject to change in the future.

Past performance and allocation

Track Record

Explore our full 10-year track record for each of our 10 risk-based, fully managed portfolios and see how our results compare against our competitors.

The past performance shown represents a composite of asset-weighted average returns for Nutmeg client portfolios, net of all fees. A composite return represents the average return of all client accounts for a given risk level on a given day, weighted by assets. Past performance is not a reliable indicator of future performance.

Nutmeg monthly returns shown in blue. Peers monthly returns for portfolios 3-10 shown in orange.

*The annualised figure is the return since inception expressed as a compound annual rate. For example, a portfolio with an annualised return of 6% corresponds to an actual return of 19.1% over three years (rather than 18% as you might expect) due to the effect of compounding.

Capital at risk. JISA rules apply.

Tax treatment depends on your individual circumstances and may be subject to change in the future.

Most people ask us

As of the 2022/23 tax year, the annual tax allowance or limit for a JISA is £9,000. For any contributions over the limit, the excess is held in a savings account in trust for the child.  

Your JISA allowance resets at the start of each tax year. The tax year starts on 6th April and your allowance, or any unused portion of it, doesn’t carry over to the next tax year.  

Find out if a junior ISA is right for you.

Only a parent or legal guardian residing in the UK can open a Nutmeg stocks and shares JISA on behalf of their child. Only the ‘registered contact’ can manage the account. 

The registered contact is the only person who can: 

  • change the account, e.g. adjust risk levels 
  • change the account provider 
  • report changes of circumstances, e.g. change of address 

For children who live outside of the UK, you can only become a registered contact if you are a crown servant (in the UK's armed forces, diplomatic service or overseas civil services, for example) and the child depends on you for care. Both criteria must apply. 

To open a Nutmeg JISA, the account holder must contribute a minimum of £100. Note, you must have an existing account* with Nutmeg to open a JISA.  

*If you’re opening a new Nutmeg account for the purpose of opening a JISA, the account can remain unfunded. 

The money in a JISA belongs to the child in all but exceptional circumstances. Please see the HMRC website for more details.

Once the child becomes 18 years old the Junior ISA is converted into a normal stocks and shares ISA in their name. 

There are two types of JISA: 

  • In a cash Junior ISA, you do not pay tax on interest. Although cash is guaranteed not to fall in value, annual inflation will have an adverse impact on its value. 
  • In a stocks and shares Junior ISA, you pay no tax on capital growth or dividends. Investments are riskier but may mean growth is potentially greater than a cash product. However, unlike cash, the value of a stocks and shares Junior ISA can go up or down. 

A child can have a cash JISA, a stocks and shares JISA, or both. 

With Nutmeg, you may only open one pot per stocks and shares JISA, but a parent or guardian may open multiple JISAs for different children. One JISA for each child.

In most cases, anyone, including parents, friends and family, can contribute on behalf of the child, provided total contributions fall below the JISA limit.

Any contributions to a JISA are not factored into your annual ISA allowance.* Nor do they count towards your Lifetime ISA limit.

*Tax treatment depends on your individual circumstances and may be subject to change in the future.

A registered contact may transfer either a JISA or Child Trust Fund from another provider to Nutmeg.

The child can access the money after they turn 18.

You cannot have a JISA as well as a Child Trust Fund (CTF). If you want to open a JISA you must transfer the CTF in.  

A Child Trust Fund is a long-term tax-free savings account for children. The CTF scheme is now closed, so you cannot apply for a new one. But people with existing CTFs can continue to contribute £9,000 a year into them.
