The number of ISA millionaires in the UK has surged to a record high, surpassing 5,000 for the first time.
A freedom of information (FOI) request from money platform Plum showed that HMRC recorded 5,070 ISA millionaires at the end of the 2022-23 period – the latest figures available – which represents a 5 per cent gain on the year before, meaning there are likely to be even more now.
