Hello, I am under similar situation. I first registered self-assessment for some non-PAYE miscellaneous incomes in 2021, this source of income ended in 2023, with the last transaction dated 25th April. I have now included in my 23/24 file. The question is, I would like to register as a sole trader, and GOV.UK website says, I quote, 'If you have registered for Self Assessment for another reason, you will need to register again.' As my initial registration was for miscellaneous income, not as sole trader, does that mean I'll have to re-register a new one and remove my old one? Thank you
