>>78372808> how the fuck is that even allowed?Who do you think would be "disallowing" America from making rules about its own citizens? America is pretty inarguably either the most powerful or second most powerful country in the world. You want to sue the IRS? The state department?
> why would you pay taxes on a country you don't live in anymore? do you need to renounce your nationality or something?Ostensibly yes. Having an American passport is extremely valuable around the world and if you want to stop paying taxes you need to stop being American. Renouncing citizenship arguably has more detriments than benefits though. Most people do not do it, even if they intend on leaving the country permanently.
