Accidental ISA Exceed - next steps?

Hi, Just replying to this: "Hi, Any excess over the ISA limit will not have the protection and any interest will be classed as taxable income. Also as a non resident you cannot pay into an ISA so any interest earned in this period will also not be exempt. You can contact us with details to tell you if any tax is due to be paid. Thank you." I have tried, I was told to call my ISA provider, who also do not know the answer...

Hi,
 

HMRC will contact you in due course to confirm that any excess will be taxable income . Thank you .

Hi, I have just found out the year allowance of across all ISAs is limited to £20000, and it seems I have made a mistake. From June 2023 to March 2024 I have paid £4000 into my lifetime ISA, while I have opened a cash ISA at September 2024 and put 20,000 into it. Please tell me what to do to rectify the problem. Thank you very much in advance.

Hi, I am terribly sorry for the typo. They are from the same year. From June 2023 to March 2024 I have paid £4000 into my lifetime ISA, and £20,000 into a cash ISA at September 2023. I therefore exceeded the amount by £4000, if I am not wrong. Sorry for the inconvenience caused. CKLee

Hi CKLee,
HMRC will contact you in due course as one of the ISA'S interest will now be taxable.
Thank you.
