I noticed a lot of digital nomads have to take a pay cut or have money saved up. Is it even possible to be a US citizen and have a remote job with good pay? I say this because if I want to live in a foreign country for say 3-6 months and then return back the US I don’t want to be making only 30k a year.
One part is definitely the host country. Some countries are stricter about it than others.
The other part is state laws usually. E.g your employer is in California where you used to live but you put your family address in Washington because you don’t have a physical address in CA anymore. CA can come after you for lying about your address to try to avoid taxation. Your visitor visas aren’t proof that you don’t live in California. You’ve just committed tax fraud.
The state thing is not a big deal if you move to another state and wrap up your relationship with the high tax state first. If you go abroad directly, then like you said it might be more difficult for you to prove that you moved to the low tax state.
I’m doing something similar and I have family in a zero income tax state which I lived in briefly before going abroad.
