Am I a non-resident of MO while living overseas?

Question about state residency status.

I currently live in Europe, and work for the U.S. federal government.

I lived in Missouri previously, maintain my voter registration there, and still have a MO drivers license. I use a friend's mailing address for the above.

Based on Missouri's residency rules, I think I qualify as a non-resident for 2025. I don't have any property in the state, nor did I spend any time there last year.

Does anyone have any experience with needing to pay state taxes in a similar situation?

The MO tax website has a flow chart, but it is still unclear.

Thanks!
