I wondered if anyone else had anything to add as I too will probably be taking a UK contract working out of London from Monday to Friday, travelling back to Switzerland just at weekends. As will be paid in sterling, UK contract and more than 180 days a year in the UK, I will be taxed at source. I presume however that if Im coming back most weekends to Switzerland where I am currently resident, I will continue to be resident as this will be more than 90 days a year? Is the only thing I can do use the double taxation treaty to avoid having to pay Swiss tax on my UK income that I have already had taxed at source in the UK? Would it benefit me to not come back to Switzerland and leave the country permanently? Any advice gratefully received. Many thanks.
