Is ISA flexible or not?

Agree in principle, but as users could potentially switch between Cash & S&S ISA, it will come. We think itā€™s simple, but it needs to total up deposits + withdrawals from 2 products, reset logic every tax year, and work for however many thousands of users. The implications of it were to falter is meh :face_with_diagonal_mouth:

Minimum data points would be:

  • Deposit Date, Deposit Amount, Deposit Account, Account ID
  • Withdrawal Date, Withdrawal Amount, Withdrawal Account, Account ID
  • LISA Allowance / start date / end date
  • ISA Allowance / start date / end date

14 data points, so a simple calculation can start to get more complicated.

For LISA available deposit, itā€™s LISA Allowance less deposits in period plus withdrawals in period.

For ISA available deposit itā€™s ISA Allowance less LISA allowance plus LISA available deposit, less ISA deposits plus ISA withdrawals in period.

Not saying we will get LISA, but the calculation needs stacked and tested.
