Question: is a htb isa a cash isa?
Answer: Help to Buy Isas count as a type of cash Isa, and you are only allowed to pay into one of these accounts in any tax year. So paying into a Help to Buy Isa (at a maximum of £200 per month) means you cannot save any of the remaining portion of your total £15,240 Isa allowance into a cash Isa in the same year.
