I was just reading that (in the UK) you can only pay into one of your owned ISAs per year.

I have a Help To Buy ISA and a separate Stocks & Shares ISA. I pay the maximum contribution of £200 into my Help To Buy ISA each month.

Given these rolling payments, when can I pay into my other ISA? And by extension, a new ISA?

You can only pay into one ISA of the same type in a (tax) year. Otherwise it's fairly flexible on how you divide your contribution, keeping to the overall limit (£20 000 in 2018-19).

There is no bar making contributions to a Help to Buy and Stocks and Shares ISA in one year. It is, however, treated as a cash ISA, so you can't have another one of those.


The help to buy ISA is also unusual in that: you can have only one of them, you have to drop feed money into it monthly, and it persists from year to year.

  • Right, that makes sense. Just to clarify, are you saying that I can only ever have 1 instance of a specific ISA ever? E.g.: I can't open a cash ISA this year and then a new one next year and then another one the following year etc...? (ignoring ISA wrappers)

  • @Petar No, it's normally by tax year but the Help to Buy ISA is the odd one out. You can pay the full £20 000 into a stocks and shares ISA on the last day of the tax year, and £20 000 the next into another stocks and shares ISA with a different provider. Obviously you'ld want to be very careful with deadlines if you were rash enough to attempt this.
