Hi I am looking for work currently, and am noticing that there are a lot of opportunities for me in helping to train AI models for $30 - $50 dollars an hour (e.g. Outlier/Data Annotation). However, they are payed directly to PayPal in USD, and therefore I'd need to ensure I am paying the correct tax on this income if I were to earn enough. I understand that I can earn approximately £1000 in any given year on this income before paying tax, but then my understanding ends. If I were to start some of these jobs, and the pay comes in, what is the process? As far as I can tell I fill out a Self Assessment form, but I wanted to be clear on this before I go on and potentially start earning. For example would this work be considered self-employed, or would it be foreign income? Any help would be appreciated - especially anyway who has dealt with this before? Cheers, Callum.
