Good news — your CT600 was accepted by HMRC. Here is what happened:

Your submission went through successfully on your third attempt (at 16:19 BST). The "unsuccessful submission" email from HMRC is about one of the two earlier attempts that were rejected before the successful one came through — HMRC sends those notifications separately and they can arrive a few minutes after the event.

Our records confirm your CT600 for MINNA'S CHILDREN [SCIO] for the period ending 31 March 2026 has status Accepted. The return is on file with HMRC and there is nothing further you need to do.

If you would like to download your accepted CT600 and tax computation, log in to your TinyTax dashboard, find the company, and click the green Accepted badge.
