We've just received a 2018/19 Class 1A payment notice addressed to one of our clients P30B(CL1A Inter).
Nothing odd about that, except we don't do their payroll or P11D and never have - everything goes straight to the client. The sub heading on the page is a completely different company. None of the employer references, accounts office etc., relate to our client. I assume they are for the other company.
HMRC just say 'if it doesn't relate to our client - send it back'. But I'm wondering if this is a one off or if HMRC have a bigger mix up on their hands. GDPR nightmare! Anyone else had similar correspondence or just me?
