Hello, I have a fixed rate cash isa account set up in tax year 2023-2024, say 500 pounds. After it matured, it was then transfer to a non isa account by the provider to a nos isa account. In this case, i fail to transfer it to other cash isa account with the isa transfer service, because it is no longer a isa account. My questions are: 1. do the interests incurred from the saving plan still tax free? 2. if I move this money to a new isa account manually, does it using my current year(2024-2025) isa allowance?
