For all parents or guardians, there’s nothing more rewarding than saving for your child’s future. With the introduction of the Junior ISA (JISA) in 2011, saving for your child’s future can not only set them up for adulthood, but it can also equip them with a valuable tax-free windfall when they turn 18.
HMRC data shows that more families than ever are using JISAs to set their children up for the future, with as many as 70,550 accounts reaching their maximum annual allowance for the 2022/2023 tax year. These figures represent a 45% increase compared to the year prior, and underline the value that Junior ISAs can hold for parents.
Crucially, Junior ISA holders will not pay tax on interest on the cash that’s saved, and any dividends that are paid out within a JISA are also entirely tax-free.
The tax-efficient credentials of the JISA are subject to an annual allowance that resets each year. But how much can you save in your JISA allowance for the 2025/2026 tax year? Let’s take a deeper look at how Junior ISAs work and how much you can contribute:
What are Junior ISAs?
Firstly, let’s look at what a Junior ISA actually is. JISAs can take one of two forms: a Cash JISA or a Stocks and Shares JISA.
While a Cash JISA focuses on allowing parents and guardians to save for their children in a similar way to a fixed-rate savings account with predictable returns, a Stocks and Shares JISA represents a stock market investment and will grow in value provided that your investments do as well.
There are a few rules to opening a Junior ISA before you get started. Firstly, your child must be under 18 years of age and living in the UK (although some exceptions apply if you’re a Crown servant).
You also can’t have both a JISA and a Child Trust Fund, but any pre-existing Child Trust Funds can be transferred into a Junior ISA.
The great thing about opening a Junior ISA is that anyone can contribute to saving for your child’s future. Whether their grandparents want to make a deposit as a birthday gift or friends are generous enough to get in on the act, a JISA can become a communal effort to brighten the future of a loved one.
As for ownership, a JISA must be managed by the child’s parent or legal guardian, but as soon as they turn 16, they’ll be able to take control over the account if the provider facilitates it. Despite this, they won’t be able to withdraw money until they turn 18.
How Much Can I Save in a JISA?
So, what is the annual allowance for a Junior ISA? For the 2025/2026 tax year, you can invest £9,000 toward your child’s future in a JISA.
Although the total amount that you can save in your Junior ISA allowance can change over time, it has historically been increasing. The government has also confirmed that it will freeze the £9,000 annual JISA allowance until 2030.
When Junior ISAs were first introduced in 2011, the annual limit was fixed at £3,600, but this was increased to £4,368 before becoming a £9,000 allowance for the 2019/2020 tax year and is still in place today.
Crucially, this allowance applies to each child you have, which can help to build significant savings for your kids as they approach adulthood.
Because you don’t have to pay any tax on the money your child earns through their JISA, it’s possible to consolidate interest earned to build an even larger nest egg for the future.
Does a JISA Affect Parental Tax Obligations?
There are plenty of reasons why opening a JISA for your child can actually improve your own tax efficiency as a parent.
Firstly, it’s important to confirm that Junior ISA allowances are in no way linked to your own ISA allowance if you have an individual savings account. This means that the £20,000 annual ISA allowance parents have won’t be reduced by saving into a JISA as well.
But even better is that Junior ISAs can serve as an excellent way to lower the amount of Inheritance Tax (IHT) that would be incurred by passing your assets down to your children or grandchildren.
By regularly saving into a Junior ISA, you can create a tax-free means of generating wealth for your loved ones while helping to ensure that your own assets stay below that all-important IHT threshold of £325,000.
Building a Nest Egg on Your Terms
The great thing about a Junior ISA is that it’s a very flexible way to save for the future of your children or grandchildren. The £9,000 tax-free allowance resets each tax year, meaning that you can create a steady stream of money to build your loved ones’ wealth ahead of turning 18, and there are no limits to who can contribute.
Crucially, there are also very few limits on how little you can contribute, too. This means that everybody can save on their terms. Whether you can hit the £9,000 allowance each year or are better suited to saving spare change, the compounding effect of saving or investing the money over many years means that even smaller deposits can make a big difference later down the line.
The Junior ISA is an excellent product to build a future for your loved ones and can help to give them the best start to their adult life without having to share their wealth with the taxman once they turn 18.
