2020 Back US Taxes (2019 income)

Hello everyone. American expat here. Is there a way to file my 2020 back taxes online for free?

If not, which forms should I be printing to mail by hand? Just a teacher’s salary, nothing fancy.


Sure, you can do it online with your NHI card.

I mean my U.S. back taxes. It’s America’s plutocratic tax quagmire that requires deft navigation, not Taiwan’s… =)
