State tax filing

Thank you for the question TomD8. As I currently live and work in NV as a permanent, exempt,  full time employee, I would say my NV address is the place I intend to return after temporary absences. My main confusion here is that there are no concrete guidelines I have found online that classify someone as a resident, part-year resident, or non resident in CA or NV. I understand there are complex cases and factors for classification include location of living, location of financial assets, drivers license, and location of purchases. In addition to what I said in my post, I do still have bank accounts in CA, but have worked and earned income exclusively in NV for 2020, albeit for the later part of the year. This is why I believe I may qualify as a NV resident with limited connections to CA, and not file a state income tax return.
