SELF-EMPLOYMENT CATEGORY:
The documents state 'Original payment booklet as proof of registration with HMRC', which I do not have any more (everything dealt with online nowadays), and they are no longer available from HMRC.
They are sending me a letter with proof of the next 2 items it mentions in the guidance (Proof of PAYE ref number, and Accounts Office ref number), so am wondering if this will suffice.
Thanks
