YSK that if Americans live outside of the US for more than 330 days a year, they don't have to pay taxes on $125,000 of their income that year
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).
But if you earn over the threshold, you're expected to pay taxes to the US government, no matter where you're actually living or working, no matter if you're also paying taxes wherever you currently are. The US is the only country in the world to assert that it has the right to tax its citizens remotely in this manner. It's not normal.
The US has double taxation treaties with over 60 countries. When you pay taxes somewhere else, you deduct all of that tax from your US taxes above the $125k.
Though I definitely agree the IRS shouldn't need these treaties, because if you're not living there, why should you even need to file?
"over the threshold, you're expected to pay taxes"
sort of, that's the "up to 125k" limit part of the FEIE(readjusted for inflation every year).
you still don't pay taxes on the first 125k.
earning more than 125k is not a problem most people have.
The problem most people have is not knowing that the feie exists in the first place and there are legal, straightforward ways to avoid paying income tax while saving money traveling.
"no matter if you're also paying taxes wherever you currently are..."
this is very iffy and depends on a lot of factors.
again, for most regular people, foreign income tax credits will erase most financial duties to the US.
Double taxation treaties are very common. What I've been told by US coworkers makes the US stand out is that you still need to file your taxes with the IRS, even when living abroad. No idea if that's actually the case.
I have lived outside my native country for a while and only had to file taxes in my country of residence (neither of which is the US), because there's a DTAA in place between the two.
Further, not doing so could impact things like voter registration depending upon the state. The whole system of US voting is a mess since it's all at the state level.
It’s not the only country. I’ve lived in another country that was just like that. I bet other countries have the same rule to avoid some tax loophole. Or just because they can.
