Do I submit anything on the HMRC portal to complete the year-end process for payroll? for example P60, P11D or P32 submissions. or is everything submitted via QB to HMRC?

Hello Adele@finovate.c, thanks for posting on the Community page, the FPs sends the P60 you dont send the P32 to hmrc   and if on advanced you can submit the P11 d via qboap. You may need to check with HMRC, as we can't advise since each company is different, they will be able to tell you if you need to submit anything to them or not through the portal.
