The £2 million ISA is emerging as a new milestone for UK investors, with Bowmore Wealth Group's research, featured in IFA Magazine, The Times, FT Adviser and The Armchair Trader, highlighting a potential shift in long-term wealth outcomes.
Analysis of HMRC data (obtained from a freedom of information request) shows that 270 individuals held more than £2 million in their ISA accounts last year, underlining the impact of consistent, tax-efficient investing.
The findings suggest that what was once considered an exceptional milestone, becoming an ISA millionaire, is now being surpassed by a growing number of disciplined investors. By investing the full annual allowance of £20,000 and achieving an average annual return of 7%, investors could build a £2 million tax-free portfolio in around 31 years.
However, behaviour remains a key factor. Holding too much in cash or making early withdrawals can significantly reduce the benefits of compounding.
John Clamp, Chartered Financial Planner at Bowmore, said:
"ISA millionaires are becoming increasingly common — but the next milestone is already within reach for many investors who take a long-term view."
"The real difference comes down to behaviour. Consistently investing the full allowance and allowing returns to compound over time can turn what seems ambitious into something achievable."
The findings reinforce the importance of long-term thinking, consistency, and making full use of available tax allowances.
