If you send your P11D submission then find there's an error to correct, you can't send this correction to HMRC using your software.

This is because HMRC only accept one electronic P11D submission per PAYE reference. 

 NOTE: If you need to amend 2022/2023 or after, follow the how do I amend P11D or P11D(b) submission article instead.

Your first step is to make any corrections required to your employees benefits in Sage 50 P11D. After this, print the P11D or P11D(b) forms as required and post these to HMRC.

1. Take a backup of your data. For help with this, visit our how to back up and restore your data article.
    NOTE: This is useful if you need to refer back to the values you submitted initially for any reason.
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
6. Post these to HMRC.
