Your CGT return is now in progress

Thanks for providing your details.
A chartered accountant will now review your documents and prepare your Capital Gains Tax return.


Next Steps: HMRC Authorisation

✅ Already provided us with your UK Property Account Number: 
  • We’ll now submit a CGT agent authorisation request via HMRC.
  • You’ll receive a notification in your Government Gateway account, or via email if set up.
  • Please log into your UK Property Account and approve the request — we can’t start work on your return until this is complete.
  • We’ll email you separately when this request has been submitted.
❓Not provided us with your UK Property Account Number: 
  • You’ll need to set up a UK Property Account with HMRC to proceed.
  • Once your account is set up:
    1. Log in and find your UK Property Account Number
    2. Email it to us or reply to your confirmation email
    3. We’ll then request agent authorisation via HMRC
    Only after you’ve approved that request can we begin work on your return.

What happens next

  1. We’ll review your documents and details. A UK chartered accountant will check everything you’ve submitted for completeness and accuracy.
  2. We’ll be in touch within 1 working day. We’ll email you if we need anything else or to confirm your submission is in progress.
  3. You’ll receive a draft for approval. Based on the information provided, we will complete all the calculations including Private Residence Relief and Lettings Relief and  send across draft calculations showing the CGT due.
  4. We’ll file your return within 3 working days. Once approved, we’ll submit your CGT return to HMRC and send you a confirmation receipt.
