You can use RTI Corrections to amend and resubmit corrections of Employment Payment Summary (EPS) files to HMRC. Once you have amended/created the EPS files, you can send them to HMRC via the FBI Mailbox. You can resubmit an EPS to HMRC any time.

Select the document EPS
Select the desired Known PAYE Scheme. OK

Note: If there is a payment to be made to HMRC you need to make this adjustment on your next EPS submission.
