HMRC have updated users on a new delay when filing a company's CT600. Some taxpayers may be experiencing a delay in receiving the online return submission response.

  • HMRC issued the update on 17 August via their 'Corporation Tax: service availability and issues' guidance.
  • Some customers have noticed a delay in the submission acknowledgement when filing their Corporation Tax self-assessment return (CT600).
  • The delay is worse around month end.
  • HMRC are working to resolve the issue but have asked those experiencing delays to wait 48 hours before contacting HMRC for an update.
  • In the meantime, they advise using the software to keep asking for a response.

With this in mind, it is strongly recommended not to leave filing CT600s until the last minute, especially at a month-end. With a potential delay in the response, it will be difficult to know whether the return has been actually submitted on time or not.
