Adding Remittance Charges Basis for tax year 2022/23

Hello, I only came to the UK in 2021. I have already reported and paid the capital gain tax earned outside the UK for more than £2,000. However I did not remit any of them to the UK, so I think I can claim for the remittance charges basis to waive this part of the tax. Am I correct on this ? If so, can you advise me on how to correct my self-assessment to add the remittance charge basis ? Thanks.

Hi,

Thank you.
