It would not be possible to re-submit the P11D and P11D(b) file as HMRC only allow one submission per PAYE reference. However, HMRC will allow for another to be sent on a case-by-case basis. You would need to contact HMRC and they would advise accordingly.
You can also check this link which describes how to correct an issue in the P11D file.
HMRC no longer accepts any paper amendments to previously submitted forms P11D and P11D(b).
