Suppose I've opened a cash ISA this tax year, and I top it up every month. It's not yet reached the yearly maximum of £15,240.
As I understand it, I can't open a second cash ISA this tax year, but I can open a stocks and shares ISA, so long as I don't invest more than £15,240 between the two.
Can I open a Help To Buy aka First Time Buyer's ISA? (obviously assuming I meet the first time buyer's criteria) I'm not sure if they count as Cash, or a third type, or if some are Cash and some are Stocks & Shares.
