why: so the government won’t be able to use your money for whatever the fuck they’re planning for the next 4 years.
as a traveler, none of my money has been funding Israel, for example.
one-step method: you basically fill out one extra tax form called FEIE while you’re doing your taxes, write down the dates you were outside of the country, and then since you aren’t in the country and are not receiving any services from the US, you don’t have to pay income tax up to a certain amount (it’s a little over 125k this year).
do you mean “another option to avoid paying taxes is renouncing your citizenship?”
in which case, yeah, extreme and still an option.
but the FEIE is way simpler and you can keep the few perks US citizenship still affords its rabble.
