Few days ago I did submit my new client`s Tax Return. After checking agents portal, I`ve noticed that HMRC calculations were missing Class 2 NI. After talking to HMRC, such a helpful person, bless him, I was told, that my client hasnt been registered for NI.... Registration were done and next week tax calc will be updated. But such a small thing - this person has been selfemployed since 15/16. Good luck to me telling him to expect letter from HMRC with all the backdated NI.
Have a good weekend peeps!
