How will I know HM Revenue and Customs (HMRC) has received the RCSL?
Once you have submitted the declaration an 'Acknowledgement' screen will be displayed showing an Acknowledgement number. Please print this page and give a copy to your client. If you don't see the 'Acknowledgement' screen you can make sure the return has been received by checking the 'Completed periods' table on the main RCSL menu screen.
