Hi,
I too have the same problem. I am a UK national living in spain for the past 15 years and currently have a job here. But I also want to setup my own online business doing freelance graphic design work (for global customers using paypal). But becoming autonomo and paying the 250 a month here is spain is crazy if I will only be getting a income of 100 or so a month to start with before business takes of. I would like to know if it is possible to register as a sole trader in the UK (and the taxes from income will be paid there) while I do the work living here in spain. Would it be wise to open a UK bank account and maybe even register the company in a relative who is already living there (how would this affect them if they are already working)?

thanks
