By now I am sure you are familiar with the rules
From 27 October 2021, you must report and pay within 60 days of completion of conveyance.
For example, if you complete the disposal on 1 November you must report and pay your Capital Gains Tax by 31 December.
If the completion date was between 6 April 2020 and 26 October 2021 you must report and pay within 30 days of completion of conveyance.
You may have to pay interest and a penalty if you do not report and pay on time.
You report the gains using this link Report and pay your Capital Gains Tax: If you have other capital gains to report – GOV.UK (www.gov.uk)
If you need a tax agent to help you you have to start the process get and X reference, give that to you tax agent/accountant, they then sent the client a link to become their agent.
You also have to report the information again on your self assessment return.
What happens if you over pay the the CGT?
You would think that doing the self assessment would generate a refund, but thats not the case, very frustrating!
The only way to recover or offset the overpaid CGT is to follow a new workaround shared by HMRC at the end of June.
The workaround suggests either:
(a) amending the UK Property Return before submitting the self-assessment return for the year to recover the overpayment that way; or
(b) submitting the self-assessment return and then calling HMRC to ask for a manual transfer to be made of the payments showing on the property account against the self-assessment account so it can then be offset against the total self-assessment bill.
