How do I know my Company Tax Return has been received?
If you stay online after submitting your Company Tax Return your software should display a 'Submission successful' page which confirms that HM Revenue and Customs (HMRC) has received your return. If you've provided an email address HMRC will also send you an email confirming they've received your return.
At busy times there may be a delay in notifying you that the submission has been successful, so it's a good idea to provide an email address. You can update or add an email address to your details by logging in to the HMRC online services and following the 'Change details' link on the 'Your account' page.
