Nearly 80,000 Junior ISAs (JISAs) hit the full £9,000 annual allowance last year - a rise of 41 per cent in just three years, according to HMRC data.
The surge suggests more parents are thinking about wealth planning far earlier than previous generations.
Rather than simply saving birthday cash, families are increasingly treating JISAs as long-term investment vehicles designed to give children a financial head start when they turn 18.
But as more families pile into these tax-free accounts, questions are emerging about whether the trend is widening the wealth gap between children who receive large financial gifts and those who do not.
Why parents are turning to Junior ISAs
Junior ISAs allow parents, relatives and friends to save or invest up to £9,000 a year for a child, with all growth and income free from tax. The money is locked away until the child turns 18.
Zoe Brett, financial planner at EQ Investors, says the rise reflects growing concern about the financial pressures facing young adults.
“Rising awareness of long-term planning is driving record JISA contributions,” she says. “JISAs are becoming ever more popular as a way for parents to future proof their children’s financial stability.”
She points to the rising cost of major life milestones. “University fees tripled in 2004 and then again in 2012 and are now linked to inflation,” she says. “Student loans have historically been predatory with high interest rates and being given out like candy to children who don’t understand the burden of carrying debt.”
Meanwhile, property has become significantly harder to afford. “Over the last 20 years, house prices have increased by up to 94 per cent according to Savills, leading to significantly higher deposit requirements,” Brett adds. “With the rising costs of education and buying a first home, it’s no wonder that parents are looking for ways to lend a helping hand.”
The power of starting early
One reason JISAs are appealing is the potential power of long-term investing.
Clare Stinton, senior personal finance analyst at Hargreaves Lansdown, says tax efficiency is part of the attraction.
“With taxes at an all time high, contributing to a JISA offers a valuable way to keep more money out of the taxman’s reach - while also giving parents the opportunity to give their child a financial leg up in life,” she says.
Money in a JISA can be invested in the stock market, giving it the potential to grow over time.
“There’s another major advantage to giving early - money in a JISA can be invested, giving the gift the potential to benefit from compound growth over the lifespan of the account, it’s the gift that keeps on giving,” Stinton says.
According to calculations from Hargreaves Lansdown, investing the full £9,000 allowance every year from birth - equivalent to £750 a month - could build a pot of around £260,000 by age 18.
EQ Investors estimates that under similar assumptions, the figure could reach about £327,000.
“For those that can afford it, investing for children early can mean children enter adulthood with no student loans and a healthy deposit for their first home,” Brett says.
But smaller sums still make a difference
Perhaps comparatively few families can afford to invest £9,000 every year, but smaller contributions can still grow into meaningful amounts.
Stinton says contributing £150 a month - £1,800 a year - from birth could build a pot of around £52,000 by age 18.
Even starting later can help: £150 a month from age 13 could grow to roughly £10,200 by adulthood. “Discipline, consistency and time are powerful tools when it comes to achieving financial goals,” Stinton says.
That is compounding in action.
Does the trend widen inequality?
While the compounding effect is powerful, it also highlights a growing divide.
Brett warns that the ability to fund a JISA is far from evenly spread.
“This is a big contrast to children from lower income families that are not afforded the same luxury and often come out of university with tens of thousands in student debt so don’t even get to start from zero, they start in the minus,” she says.
Even modest savings can illustrate the gap. Brett calculates that saving £50 a month into a JISA could build a pot of about £20,399 by age 18.
“This widens the wealth divide and unintentionally creates greater inequality,” she says.
Passing wealth earlier
The rising popularity of JISAs also reflects a broader shift in how families think about passing wealth between generations.
“A JISA doesn’t have to be a solo effort from parents either,” Stinton says.

“Once it’s open, friends and family can contribute too, including grandparents.”
“For those worried about upcoming changes to inheritance tax, gifting money during their lifetime can be a practical way to support loved ones while also reducing the value of their estate and any potential tax liability.”
Stinton says involving children in conversations about their investments can also help build financial understanding.
“You can talk to them about the companies they are invested in and how they are performing,” she says.
“They can learn valuable lessons around market volatility and taking a long term approach that can lead to a lifelong investment habit.”
For many families, learning that saving consistently over time can build something meaningful may be just as valuable as the money itself.
When investing, your capital is at risk and you may get back less than invested. Past performance doesn’t guarantee future results.
