8.5 Once your tax return has been submitted to HMRC, no refund will be available as the Service has been fully performed.

9. Submission and HMRC

9.1 Before we submit your tax return, we will provide you with your Self Assessment tax return and a summary for your review and approval. You must check this carefully. By approving your return, you confirm that the information is accurate and complete to the best of your knowledge.
