You only need to report to HMRC if you have been issued with a paper P11D(b), an electronic notice to file a P11D(b) or a reminder to file a P11D(b) letter. This would happen if you have filed P11Ds previously.
If you have been asked to submit a P11D(b) to HMRC but have nothing to report then you will need to tell them this is the case, because if not they will issue penalties as they will assume you are just late.
However, you can click here to inform HMRC that you have nothing to report.
P11Ds only have to be submitted to HMRC for each employee that you have provided benefits or expenses to.
The filing deadline for forms P11D and P11D(b) is 6 July following the tax year and penalties will be issued if the forms are filed late.
