HMRC only accept one electronic P11D submission for each PAYE reference from your software.

This means you can't re-submit a P11D submisson from your software if your initial submission contains any incorrect processing.

 NOTE: If you need to amend 2021/2022 or before, follow the amend a P11D submission for the 2021/2022 tax year and before article.  

Before you can send HMRC any amendments, you need to correct your employees' benefits correctly in Sage 50 P11D:

1. Take a backup of your data. For help with doing this, follow the how to back up and restore your data article.
    NOTE: Taking a backup now is useful if you ever need to refer back to the values you submitted initially.
2. Make the relevant corrections.
3. Check the affected employees' P11D forms and the P11D(b) declaration are correct.
4. Provide the affected employees with a new copy of their P11D form.
5. Print the amended P11D and P11D(b) forms:
   • Print your employee P11D forms
   • Print your Employers P11D(b) Declaration

You've corrected your P11D software and printed forms that include the changes. Next, enter the information from the corrected forms into HMRC's online form.
