Hello Dila, if you wish to transfer your full ISA from Vanguard to us, you will need to select ‘Yes, transfer current tax year ISA’ and input the amount of money that was contributed on/after April 6th 2024 as this will be the total current tax year contributions. Then for previous years, you will need to provide the value held in the account before April 6th 2024. We understand the final amount will be different to what we may receive in the transfer, this will not the affect the transfer. I hope this helps.
