Do I need to file a return if I got an extension but don't owe anything?
I've lived abroad ever since I became a taxpayer. My current country and the US have an agreement to avoid double-taxation. Since I only work local jobs and pay the local country's taxes, and earn way below the US's required amount for filing, I was under the impression that I didn't need to file in the US. I haven't for these past few years and nothing's happened.
This year I thought I should, just to be in the system, and also because I wasn't clear as to whether I'd get a stimulus check. The process turned out to be far more complicated than I expected, and I applied for an extension because I simply didn't have time to figure it all out. However, now I'm not sure whether I needed to bother after all. But since I got the extension, does that now obligate me to file a return, even though I owe nothing? One reason why I'm wondering is that I didn't get a stimulus check, and have learned that I could've submitted a form saying that I'm a non-filer, but it's not recommended that you do this if you file a 2019 return.
