sorry my English maybe is not good enough in (I am not English 😂) , I meant if the DTV is for 6 months, and after that you can extend it another 6 months, how is it possible you need to extend it already if you got it in July? You should do it after 6 months right? Maybe there is something I did not understand.
The common rule, as I said before , is pay taxes where you live more than 180+ days a tax year, but THERE ARE EXCEPTIONS, I am not an accountant, and I do not know all the exceptions, I just tell my personal experience working as a permanent in the UK, and paying my taxes in Thailand, that's it 😎
