Clarification on ISA Accumulate Balance Limit

Dear HMRC Admin Team, I am writing to seek clarification regarding the Individual Savings Account (ISA) accumulate balance limit. I understand that there is no limit to the total amount of money that can be held within an ISA. However, I would like to confirm if there is a limit on the total cumulative balance that can be accumulated over multiple tax years. To illustrate my query, please consider the following scenario: Year 1: I contribute the maximum annual allowance of £20,000 to my ISA. Year 2: I continue to contribute the maximum annual allowance of £20,000. In this scenario, my total ISA balance at the end of Year 2 would be £40,000. 1. Is there a restriction on the total cumulative balance that can be held within an ISA over multiple tax years? 2. Additionally, I would like to know if it is necessary to withdraw the entire ISA balance and re-open a new ISA every year to avoid any potential limitations on the cumulative balance. Thank you for your time and assistance in clarifying this matter. I look forward to your prompt response. Sincerely,
