You are only allowed to fund one Stocks & Shares ISA in any given tax year. If you have already funded a Stocks & Shares ISA elsewhere this tax year, you won’t be able to fund another one with us.
If you have opened an ISA with us and have already contributed to a Stocks & Shares ISA elsewhere this tax year, please let us know as we’ll need to close it.
You can deposit cash in multiple different types of ISA. For example, if you have already opened and funded a Cash ISA, you’ll be able to deposit cash in a Stocks & Shares ISA in the same tax year.
For more information, you can take a look at the Government website.
