Update of NI number for employee for P11D that has already been submitted

Hi, I have submitted our P11D for all our staff members for the tax year 2022-23 and for some staff members, their NI numbers were not known at the time of the P11D submission. I now have their NI number but how can I update this on the P11D that I have submitted via the HMRC website? Thanks

Hi Emily Kim,

A NI number is not a requirement for HMRC, as long as the name, address and Date of Birth are correct our system should be able to locate the correct record.

Thank you.
