Moving ISA funds within same tax year

Hello I opened an ISA earlier on in the 23/24 tax year (May), with an investment of the full ISA allowance of funds (£20,000) along with funds from an ISA transfer from previous tax years. Since the interest rates have now increased significantly, I would like to transfer the entirety of the funds in the May ISA into a new ISA with a different provider via an ISA transfer. This would result in the closure of the account opened in May. The wording in the standard ISA terms and conditions, as well as the gov.uk articles on the matter seem a little ambiguous and suggest that only a single ISA can be opened in a tax year. However I would be closing the previous account, and while I would have 'opened' 2 ISAs within the tax year, only one ISA opened in this tax year would be open at any one time. Can I confirm that this is allowed under the ISA legislation before I go ahead with the transfer? Kind Regards

Hi

You can transfer it as long as it is done by the bank/building society - take a look at the link here Individual Savings Accounts (ISAs)

Thank you
