I am a foreigner working full-time in the UK and studying part time at Uni. I want to study full time. In my old country, I used to draw and fix computers to earn some extra money.
What should I do if I want to become self-employed and keep my full time job? I don't want to sell any items or produce anything. I want to sell services only (Little things like painting a picture according to the clients idea, printing photos, fixing issues with computers). I predict my income to be about £50 per month or less on average.
I know about self-assessment form. But is it that simple? Is it the only thing I need to apply for? Do I need to pay any fees regularly like national insurance?
