Junior ISAs: How To Give Your Kids a Head Start on Saving

Launched in 2011, the Junior ISA (JISA) has quickly become one of the most effective ways for parents to build a nest egg for their children as they grow up. With a wide range of tax-free earnings to unlock later in life, it’s clear to see why the Junior Individual Savings Account boom isn’t slowing down any time soon. 

Working similarly to a typical adult ISA, around 1.25 million Junior ISA accounts were subscribed to for the tax year 2022 to 2023. According to Moneyweek data, many savers have used JISAs to build a considerable pot of savings. 

Figures show that in the 2021 to 2022 tax year, 370 children held Junior ISA accounts worth more than £200,000. Furthermore, the top 50 JISA accounts from the same period in the UK averaged a sizeable £761,000, meaning that the holders were well on course to become millionaires by their 20s. 

Junior Individual Savings Accounts come in two traditional forms, Cash JISAs and Stocks and Shares JISAs. With no taxation on earnings like Capital Gains Tax, Junior ISAs are proving highly lucrative for families with the resources to save for their children’s future. 

Additionally, Junior ISAs are available to anybody under 18 years of age provided they live in the United Kingdom. However, it’s still possible for your child to obtain a JISA if you’re a Crown servant (in the UK’s armed forces or on diplomatic service) overseas or if they depend on your care. 

But how exactly do Junior ISAs differ from their adult counterparts? And in what ways can parents maximise their children’s savings using a JISA? Let’s take a deeper look at one of the United Kingdom’s most effective investment strategies for youngsters: 

Why are JISAs so Effective? 

Junior ISAs allow you to invest and build a savings pot on behalf of your children without being taxed on the interest or gains made over time. 

This is especially important for parents because, if an alternative saving method generates over £500 in interest over a year, it would be taxed at the parent’s tax rate for all the interest, not only the part that’s over £500. 

Instead, a Junior ISA allows all interest and gains to go tax-free, meaning that your children will see all of the savings account’s returns. 

Crucially, these profits can also be reinvested within the Junior ISA account in a process known as compounding, which can help to generate far more effective profits over time while leveraging faster growth. 

Although you’re able to open a Junior ISA even before your child is born, an annual allowance of £9,000 each tax year means that you’ll be limited in how much you can add to the savings pot. 

The tax-free savings allowance of £9,000 is in place for the tax year 2024 to 2025 and is liable to change from year to year. 

If your child holds a Cash ISA and a Stocks and Shares ISA, the £9,000 allowance is a combined total for the tax year. This means that you can save £6,000 in a cash JISA and £3,000 in a stocks and shares JISA but you couldn’t save £9,000 in both Junior ISAs, for instance.

This allowance doesn’t carry over, so you’ll need to hit your £9,000 allowance between April 6th and April 5th each tax year to ensure that you’re saving as much as possible.

Theoretically, saving £9,000 each tax year until your child is 18 would build a pot of £162,000 even before accounting for interest, earnings, and other variables that could help to boost your child’s savings. 

However, to maximise your child’s Junior ISA allowance each year involves significant savings stored away into an account that can’t be touched for many years, so it’s important to only ever add money that you’re comfortable parting with for the foreseeable future. 

Who Can Add to a Junior ISA? 

The great thing about Junior ISAs is that anyone can contribute. Whether you’re a parent aiming to build a nest egg for your child’s future, or are an auntie, cousin, grandparent, or even family friend, building a JISA can be a fully collaborative investment strategy. 

As a parent, you’ll also have full control over your child’s Junior ISA until they turn 16, at which point, they’re free to manage their savings as they wish. However, the funds will be unavailable to withdraw until your child turns 18. At this point, they can either take the money out, convert their account into a traditional adult ISA, or reinvest it in any way they like. 

Are Junior ISAs Safe? 

The cash you contribute to a Junior ISA provided by UK banks or building societies is protected by the Financial Services Compensation Scheme (FSCS). This provides a savings protection limit of £85,000 per authorised firm. 

Despite this, it’s always worth conducting some research regarding how your chosen JISA provider will invest your savings, and assessing their track record when it comes to Stocks and Shares JISAs. 

With the right level of due diligence, you can open an effective savings account that will grow tax-free to provide a nest egg for your child’s future. With many youngsters throughout the UK already benefiting from saving with a Junior ISA, there’s no time like the present to set your child up for adulthood.
