Long time reader, first time poster. Fairly new to practice but not the profession.
I know this is similar to the query about the small income but it is slightly different as HMRC will have the missing info.
Lovely client denied existence of P45 before we submitted his SA (he does sporadic work) and now he has given it to us (bless). He has paid his tax and there is no additional payment required (ie no loss to HMRC).
Should we let HMRC know or resubmit? I wouldn't bother normally but they will have the P60 and it is not on the return ie return is incomplete. Are HMRC going to notice I wonder, it is £500 tax and his total income is pretty low.
