Hi Jade Wong,
You opened a cash ISA on 28/03/23 (22/23 tax year) 10/05/23 (23/24) & 23/03/24 (23/24).
As you have opened two cash ISAs in the same tax year, you will need to close one of them.
You should discuss this with your ISA providers.
Any interest arising from the closed ISA, will be taxable and should be declared to HMRC.
Individual Savings Accounts (ISAs).
Thank you.
