CIS - Amend CIS returns before submitting
It would be very useful to be able to amend CIS returns on Xero before final submission (as it is possible with VAT returns).

Thank you for raising this idea about the ability to amend CIS returns before submitting them. As per HMRC requirements, the CIS deduction is an event that is legally tied to the cash transaction of a payment being made. Because of this, the final return is based on these completed cash transactions, and any changes must be made through HMRC's official amendment process. Therefore, the ability to edit the return before submission is outside of Xero's control as we must adhere to the strict requirements set by HMRC for the CIS scheme. While we understand this isn't the answer you were hoping for, we want to be transparent about why this is not something we can build. We will continue to explore any potential solutions that may align with HMRC's future requirements, but for now, we must follow their strict compliance rules ✨
