As an expat living/working abroad with no income earned in my previous state of residence (Wisconsin in 2021), do I have to file Wisconsin state taxes? Or just Federal?

I moved from Wisconsin to South Korea in 2021 and have been paying to file both my federal and state taxes since then.  It has come to my attention that I might not have to file and pay for my Wisconsin state taxes form since I'm not a resident of Wisconsin anymore, and none of my income earned was in WI or in the USA for that matter.  Is this correct?  Am I only obligated to fill out and pay for my federal tax form? Or do I have to continue filling out and paying for the Wisconsin state form too?

A non-resident of Wisconsin with no Wisconsin-source income has no income tax obligation to the State of Wisconsin.

Thank you! Does this mean I should be okay to only file a federal return and not file a state return at all?

Correct - unless you have income sourced to another state.
