I'm an EU national, currently resident in the UK and employed full time, paying tax through PAYE and NI. I already know that I could make additional £50 per month on average doing small jobs (IT help, printing images and painting pictures). I suppose they would all classify as services, not trading items. So I want to become self-employed alongside working full time as an employee.
So far I've learned that my predicted income would be too low to pay any national insurance, so the only thing I need to do is to register for self-assessment. (Please correct me if I'm wrong)
Should I register for a business tax, too? Or is self-assessment alone enough?
And do I need to register as a sole trader?
