Flexible ISAs allow tax-free withdrawals and repayments within the same tax year, aiding effective money management.

Flexible ISAs provide a tax-beating savings feature, allowing users to withdraw money without affecting their annual allowance, as long as it's repaid within the same tax year. This can help adjust financial behavior and prevent loss of interest from easy-access tax savings. Simon Lambert recommends these accounts as a crucial component of effective money management, especially for those with large cash reserves and the capacity to fill their ISA.
