CG sale of property

I reported and paid CG on sale of property in Dec 22. I had to estimate my income for 22/23 because of 60 day rule. I have overestimated my income by c £1200, so have overpaid. . I am now completing my SA for 22/23. Do I need to complete the CG section on SA form, when I’ve already submitted and paid CG? Or should I amend my original CG submission with the correct income for 22/23. How will the overpayment be returned?

Hi 

You complete the CG section of the return and show that you have already declares/paid this. this then confirms any refund that will be due for the tax already paid.
Once submitted, please allow 72 hours to contact us for the repayment to be issued - it is different systems so is not done automatically.

Thank you
